-# Complex numbers
-# ---------------
-
-# [Now that Python has a complex data type built-in, this is not very
-# useful, but it's still a nice example class]
-
-# This module represents complex numbers as instances of the class Complex.
-# A Complex instance z has two data attribues, z.re (the real part) and z.im
-# (the imaginary part).  In fact, z.re and z.im can have any value -- all
-# arithmetic operators work regardless of the type of z.re and z.im (as long
-# as they support numerical operations).
-#
-# The following functions exist (Complex is actually a class):
-# Complex([re [,im]) -> creates a complex number from a real and an imaginary part
-# IsComplex(z) -> true iff z is a complex number (== has .re and .im attributes)
-# ToComplex(z) -> a complex number equal to z; z itself if IsComplex(z) is true
-#                 if z is a tuple(re, im) it will also be converted
-# PolarToComplex([r [,phi [,fullcircle]]]) ->
-#       the complex number z for which r == z.radius() and phi == z.angle(fullcircle)
-#       (r and phi default to 0)
-# exp(z) -> returns the complex exponential of z. Equivalent to pow(math.e,z).
-#
-# Complex numbers have the following methods:
-# z.abs() -> absolute value of z
-# z.radius() == z.abs()
-# z.angle([fullcircle]) -> angle from positive X axis; fullcircle gives units
-# z.phi([fullcircle]) == z.angle(fullcircle)
-#
-# These standard functions and unary operators accept complex arguments:
-# abs(z)
-# -z
-# +z
-# not z
-# repr(z) == `z`
-# str(z)
-# hash(z) -> a combination of hash(z.re) and hash(z.im) such that if z.im is zero
-#            the result equals hash(z.re)
-# Note that hex(z) and oct(z) are not defined.
-#
-# These conversions accept complex arguments only if their imaginary part is zero:
-# int(z)
-# float(z)
-#
-# The following operators accept two complex numbers, or one complex number
-# and one real number (int, long or float):
-# z1 + z2
-# z1 - z2
-# z1 * z2
-# z1 / z2
-# pow(z1, z2)
-# cmp(z1, z2)
-# Note that z1 % z2 and divmod(z1, z2) are not defined,
-# nor are shift and mask operations.
-#
-# The standard module math does not support complex numbers.
-# The cmath modules should be used instead.
-#
-# Idea:
-# add a class Polar(r, phi) and mixed-mode arithmetic which
-# chooses the most appropriate type for the result:
-# Complex for +,-,cmp
-# Polar   for *,/,pow

-# Class Date supplies date objects that support date arithmetic.
-#
-# Date(month,day,year) returns a Date object.  An instance prints as,
-# e.g., 'Mon 16 Aug 1993'.
-#
-# Addition, subtraction, comparison operators, min, max, and sorting
-# all work as expected for date objects:  int+date or date+int returns
-# the date `int' days from `date'; date+date raises an exception;
-# date-int returns the date `int' days before `date'; date2-date1 returns
-# an integer, the number of days from date1 to date2; int-date raises an
-# exception; date1 < date2 is true iff date1 occurs before date2 (&
-# similarly for other comparisons); min(date1,date2) is the earlier of
-# the two dates and max(date1,date2) the later; and date objects can be
-# used as dictionary keys.
-#
-# Date objects support one visible method, date.weekday().  This returns
-# the day of the week the date falls on, as a string.
-#
-# Date objects also have 4 read-only data attributes:
-#   .month  in 1..12
-#   .day    in 1..31
-#   .year   int or long int
-#   .ord    the ordinal of the date relative to an arbitrary staring point
-#
-# The Dates module also supplies function today(), which returns the
-# current date as a date object.
-#
-# Those entranced by calendar trivia will be disappointed, as no attempt
-# has been made to accommodate the Julian (etc) system.  On the other
-# hand, at least this package knows that 2000 is a leap year but 2100
-# isn't, and works fine for years with a hundred decimal digits <wink>.

-'''
-A class which presents the reverse of a sequence without duplicating it.
-From: "Steven D. Majewski" <sdm7g@elvis.med.virginia.edu>
-
-It works on mutable or inmutable sequences.
-
->>> chars = list(Rev('Hello World!'))
->>> print ''.join(chars)
-!dlroW olleH
-
-The .forw is so you can use anonymous sequences in __init__, and still
-keep a reference the forward sequence. )
-If you give it a non-anonymous mutable sequence, the reverse sequence
-will track the updated values. ( but not reassignment! - another
-good reason to use anonymous values in creating the sequence to avoid
-confusion. Maybe it should be change to copy input sequence to break
-the connection completely ? )

-Subject: Re: What language would you use?
-From: Tom Christiansen <tchrist@mox.perl.com>
-Date: 6 Nov 1994 15:14:51 GMT
-Newsgroups: comp.lang.python,comp.lang.tcl,comp.lang.scheme,comp.lang.misc,comp.lang.perl
-Message-Id: <39irtb$3t4@csnews.cs.Colorado.EDU>
-References: <39b7ha$j9v@zeno.nscf.org> <39hhjp$lgn@csnews.cs.Colorado.EDU> <39hvsu$dus@mathserv.mps.ohio-state.edu>

-[...]
-If you're really into benchmarks, I'd love it if someone were to code up
-the following problems in tcl, python, and scheme (and whatever else you'd
-like).  Separate versions (one optimized for speed, one for beauty :-) are
-ok.  Post your code so we can time it on our own systems.
-
-0)  Factorial Test  (numerics and function calls)
-
-        (we did this already)
-
-1)  Regular Expressions Test
-
-    Read a file of (extended per egrep) regular expressions (one per line), 
-    and apply those to all files whose names are listed on the command line.
-    Basically, an 'egrep -f' simulator.  Test it with 20 "vt100" patterns
-    against a five /etc/termcap files.  Tests using more elaborate patters
-    would also be interesting.  Your code should not break if given hundreds
-    of regular expressions or binary files to scan.  
-
-2)  Sorting Test
-
-    Sort an input file that consists of lines like this
-
-        var1=23 other=14 ditto=23 fred=2
-
-    such that each output line is sorted WRT to the number.  Order
-    of output lines does not change.  Resolve collisions using the
-    variable name.   e.g.
-
-        fred=2 other=14 ditto=23 var1=23 
-
-    Lines may be up to several kilobytes in length and contain
-    zillions of variables.
-
-3)  System Test
-
-    Given a list of directories, report any bogus symbolic links contained
-    anywhere in those subtrees.  A bogus symbolic link is one that cannot
-    be resolved because it points to a nonexistent or otherwise
-    unresolvable file.  Do *not* use an external find executable.
-    Directories may be very very deep.  Print a warning immediately if the
-    system you're running on doesn't support symbolic links.
-
-
-I'll post perl solutions if people post the others.

-ncurses demos
-=============

-These demos are converted from the C versions in the ncurses
-distribution, and were contributed by Thomas Gellekum <tg@FreeBSD.org>
-I didn't strive for a `pythonic' style, but bluntly copied the
-originals. I won't attempt to `beautify' the program anytime soon, but
-I wouldn't mind someone else making an effort in that direction, of
-course.

-rain.py         -- raindrops keep falling on my desktop
-tclock.py       -- ASCII clock, by Howard Jones
-xmas.py         -- I'm dreaming of an ASCII christmas
-
-Please submit bugfixes and new contributions to the Python bug tracker.

-"""repeat [-i SECONDS] <shell-command>

-This simple program repeatedly (at 1-second intervals) executes the
-shell command given on the command line and displays the output (or as
-much of it as fits on the screen).  It uses curses to paint each new
-output on top of the old output, so that if nothing changes, the
-screen doesn't change.  This is handy to watch for changes in e.g. a
-directory or process listing.
-
-The -i option lets you override the sleep time between executions.

-To end, hit Control-C.

-This directory show how to embed the Python interpreter in your own
-application.  The file demo.c shows you all that is needed in your C
-code.
-
-To build it, you may have to edit the Makefile:
-
-1) set blddir to the directory where you built Python, if it isn't in
-the source directory (../..)
-
-2) change the variables that together define the list of libraries
-(MODLIBS, LIBS, SYSLIBS) to link with, to match their definitions in
-$(blddir)/Modules/Makefile
-
-An additional test program, loop.c, is used to experiment with memory
-leakage caused by repeated initialization and finalization of the
-interpreter.  It can be build by saying "make loop" and tested with
-"make looptest".  Command line usage is "./loop <python-command>",
-e.g. "./loop 'print 2+2'" should spit out an endless number of lines
-containing the number 4.

-Filesystem, RCS and CVS client and server classes
-=================================================
-
-*** See the security warning at the end of this file! ***
-
-This directory contains various modules and classes that support
-remote file system operations.
-
-CVS stuff
----------
-
-rcvs			Script to put in your bin directory
-rcvs.py			Remote CVS client command line interface
-
-cvslib.py		CVS admin files classes (used by rrcs)
-cvslock.py		CVS locking algorithms
-
-RCS stuff
----------
-
-rrcs			Script to put in your bin directory
-rrcs.py			Remote RCS client command line interface
-
-rcsclient.py		Return an RCSProxyClient instance
-			(has reasonable default server/port/directory)
-
-RCSProxy.py		RCS proxy and server classes (on top of rcslib.py)
-
-rcslib.py		Local-only RCS base class (affects stdout &
-			local work files)
-
-FSProxy stuff
--------------
-
-sumtree.py		Old demo for FSProxy
-cmptree.py		First FSProxy client (used to sync from the Mac)
-FSProxy.py		Filesystem interface classes
-
-Generic client/server stuff
----------------------------
-
-client.py		Client class
-server.py		Server class
-
-security.py		Security mix-in class (not very secure I think)
-
-Other generic stuff
--------------------
-
-cmdfw.py		CommandFrameWork class
-			(used by rcvs, should be used by rrcs as well)
-
-
-Client/Server operation
------------------------
-
-The Client and Server classes implement a simple-minded RPC protocol,
-using Python's pickle module to transfer arguments, return values and
-exceptions with the most generality.  The Server class is instantiated
-with a port number on which it should listen for requests; the Client
-class is instantiated with a host name and a port number where it
-should connect to.  Once a client is connected, a TCP connection is
-maintained between client and server.
-
-The Server class currently handles only one connection at a time;
-however it could be rewritten to allow various modes of operations,
-using multiple threads or processes or the select() system call as
-desired to serve multiple clients simultaneously (when using select(),
-still handling one request at a time).  This would not require
-rewriting of the Client class.  It may also be possible to adapt the
-code to use UDP instead of TCP, but then both classes will have to be
-rewritten (and unless extensive acknowlegements and request serial
-numbers are used, the server should handle duplicate requests, so its
-semantics should be idempotent -- shrudder).
-
-Even though the FSProxy and RCSProxy modules define client classes,
-the client class is fully generic -- what methods it supports is
-determined entirely by the server.  The server class, however, must be
-derived from.  This is generally done as follows:
-
-	from server import Server
-	from client import Client
-
-	# Define a class that performs the operations locally
-	class MyClassLocal:
-		def __init__(self): ...
-		def _close(self): ...
-
-	# Derive a server class using multiple inheritance
-	class MyClassServer(MyClassLocal, Server):
-		def __init__(self, address):
-			# Must initialize MyClassLocal as well as Server
-			MyClassLocal.__init__(self)
-			Server.__init__(self, address)
-		def _close(self):
-			Server._close()
-			MyClassLocal._close()
-
-	# A dummy client class
-	class MyClassClient(Client): pass
-
-Note that because MyClassLocal isn't used in the definition of
-MyClassClient, it would actually be better to place it in a separate
-module so the definition of MyClassLocal isn't executed when we only
-instantiate a client.
-
-The modules client and server should probably be renamed to Client and
-Server in order to match the class names.
-
-
-*** Security warning: this version requires that you have a file
-$HOME/.python_keyfile at the server and client side containing two
-comma- separated numbers.  The security system at the moment makes no
-guarantees of actuallng being secure -- however it requires that the
-key file exists and contains the same numbers at both ends for this to
-work.  (You can specify an alternative keyfile in $PYTHON_KEYFILE).
-Have a look at the Security class in security.py for details;
-basically, if the key file contains (x, y), then the security server
-class chooses a random number z (the challenge) in the range
-10..100000 and the client must be able to produce pow(z, x, y)
-(i.e. z**x mod y).

-"""CVS locking algorithm.

-CVS locking strategy
-====================
-
-As reverse engineered from the CVS 1.3 sources (file lock.c):
-
-- Locking is done on a per repository basis (but a process can hold
-write locks for multiple directories); all lock files are placed in
-the repository and have names beginning with "#cvs.".
-
-- Before even attempting to lock, a file "#cvs.tfl.<pid>" is created
-(and removed again), to test that we can write the repository.  [The
-algorithm can still be fooled (1) if the repository's mode is changed
-while attempting to lock; (2) if this file exists and is writable but
-the directory is not.]
-
-- While creating the actual read/write lock files (which may exist for
-a long time), a "meta-lock" is held.  The meta-lock is a directory
-named "#cvs.lock" in the repository.  The meta-lock is also held while
-a write lock is held.
-
-- To set a read lock:
-
-        - acquire the meta-lock
-        - create the file "#cvs.rfl.<pid>"
-        - release the meta-lock
-
-- To set a write lock:
-
-        - acquire the meta-lock
-        - check that there are no files called "#cvs.rfl.*"
-                - if there are, release the meta-lock, sleep, try again
-        - create the file "#cvs.wfl.<pid>"
-
-- To release a write lock:
-
-        - remove the file "#cvs.wfl.<pid>"
-        - rmdir the meta-lock
-
-- To release a read lock:
-
-        - remove the file "#cvs.rfl.<pid>"
-
-
-Additional notes
-----------------
-
-- A process should read-lock at most one repository at a time.
-
-- A process may write-lock as many repositories as it wishes (to avoid
-deadlocks, I presume it should always lock them top-down in the
-directory hierarchy).
-
-- A process should make sure it removes all its lock files and
-directories when it crashes.
-
-- Limitation: one user id should not be committing files into the same
-repository at the same time.
-
-
-Turn this into Python code

-This is a Python interface to Sun RPC, designed and implemented mostly
-by reading the Internet RFCs about the subject.
-
-*** NOTE: xdr.py has evolved into the standard module xdrlib.py ***
-
-There are two library modules, xdr.py and rpc.py, and several example
-clients: mountclient.py, nfsclient.py, and rnusersclient.py,
-implementing the NFS Mount protocol, (part of) the NFS protocol, and
-the "rnusers" protocol (used by rusers(1)), respectively.  The latter
-demonstrates the use of broadcast via the Port mapper's CALLIT
-procedure.
-
-There is also a way to create servers in Python.
-
-To test the nfs client, run it from the shell with something like this:
-
-  python -c 'import nfsclient; nfsclient.test()' [hostname [filesystemname]]
-
-When called without a filesystemname, it lists the filesystems at the
-host; default host is the local machine.
-
-Other clients are tested similarly.
-
-For hostname, use e.g. wuarchive.wustl.edu or gatekeeper.dec.com (two
-hosts that are known to export NFS filesystems with little restrictions).
-
-There are now two different RPC compilers:
-
-1) Wim Lewis rpcgen.py found on http://www.omnigroup.com/~wiml/soft/stale-index.html#python. 
-
-2) Peter Åstrands rpcgen.py, which is part of "pynfs" (http://www.cendio.se/~peter/pynfs/).

-# Fix Python source files to use the new equality test operator, i.e.,
-#       if x = y: ...
-# is changed to
-#       if x == y: ...
-# The script correctly tokenizes the Python program to reliably
-# distinguish between assignments and equality tests.
-#
-# Command line arguments are files or directories to be processed.
-# Directories are searched recursively for files whose name looks
-# like a python module.
-# Symbolic links are always ignored (except as explicit directory
-# arguments).  Of course, the original file is kept as a back-up
-# (with a "~" attached to its name).
-# It complains about binaries (files containing null bytes)
-# and about files that are ostensibly not Python files: if the first
-# line starts with '#!' and does not contain the string 'python'.
-#
-# Changes made are reported to stdout in a diff-like format.
-#
-# Undoubtedly you can do this using find and sed or perl, but this is
-# a nice example of Python code that recurses down a directory tree
-# and uses regular expressions.  Also note several subtleties like
-# preserving the file's mode and avoiding to even write a temp file
-# when no changes are needed for a file.
-#
-# NB: by changing only the function fixline() you can turn this
-# into a program for a different change to Python programs...

-                             NEWSLIST
-                             ========    
-            A program to assist HTTP browsing of newsgroups
-            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-WWW browsers such as NCSA Mosaic allow the user to read newsgroup
-articles by specifying the group name in a URL eg 'news:comp.answers'.
-
-To browse through many groups, though, (and there are several thousand
-of them) you really need a page or pages containing links to all the
-groups. There are some good ones out there, for example,
-
-    http://info.cern.ch/hypertext/DataSources/News/Groups/Overview.html
-
-is the standard one at CERN, but it only shows the groups available there,
-which may be rather different from those available on your machine.
-
-Newslist is a program which creates a hierarchy of pages for you based
-on the groups available from YOUR server. It is written in python - a
-splendid interpreted object-oriented language which I suggest you get
-right now from the directory /pub/python at ftp.cwi.nl, if you haven't
-already got it.
-
-You should be able to see some sample output by looking at:
-   http://pelican.cl.cam.ac.uk/newspage/root.html
-
-Descriptions of newsgroups can be added from a file with one group
-per line. eg:
-
-	alt.foo   Articles about foo
-	comp.bar  Programming in 'bar' and related languages
-
-A suitable list detailing most groups can be found at ftp.uu.net in
-/uunet-info/newsgroups.gz.
-
-Make sure you read the information at the beginning of the program source and
-configure the variables before running.
-
-In addition to python, you need:
-
-	An NNTP-based news feed.
-	A directory in which to put the pages.
-
-The programming is not very beautiful, but it works!  It comes with no
-warranty, express or implied, but with the hope that some others may
-find it useful.
-
-Comments, improvements & suggestions welcomed.

-# Newslist  $Revision$
-#
-# Syntax:
-#    newslist [ -a ]
-#
-# This is a program to create a directory full of HTML pages
-# which between them contain links to all the newsgroups available
-# on your server.
-#
-# The -a option causes a complete list of all groups to be read from
-# the server rather than just the ones which have appeared since last
-# execution. This recreates the local list from scratch. Use this on
-# the first invocation of the program, and from time to time thereafter.
-#   When new groups are first created they may appear on your server as
-# empty groups. By default, empty groups are ignored by the -a option.
-# However, these new groups will not be created again, and so will not
-# appear in the server's list of 'new groups' at a later date. Hence it
-# won't appear until you do a '-a' after some articles have appeared.
-#
-# I should really keep a list of ignored empty groups and re-check them
-# for articles on every run, but I haven't got around to it yet.
-#
-# This assumes an NNTP news feed.
-#
-# Feel free to copy, distribute and modify this code for
-# non-commercial use. If you make any useful modifications, let me
-# know!

-# FTP client can be built, and you are welcome to extend it to suit
-# it to your needs...
-#
-# How it works (assuming you've read the RFC):
-#
-# User commands are passed uninterpreted to the server.  However, the
-# user never needs to send a PORT command.  Rather, the client opens a
-# port right away and sends the appropriate PORT command to the server.
-# When a response code 150 is received, this port is used to receive
-# the data (which is written to stdout in this version), and when the
-# data is exhausted, a new port is opened and a corresponding PORT
-# command sent.  In order to avoid errors when reusing ports quickly
-# (and because there is no s.getsockname() method in Python yet) we
-# cycle through a number of ports in the 50000 range.

-# Coroutine implementation using Python threads.
-#
-# Combines ideas from Guido's Generator module, and from the coroutine
-# features of Icon and Simula 67.
-#
-# To run a collection of functions as coroutines, you need to create
-# a Coroutine object to control them:
-#    co = Coroutine()
-# and then 'create' a subsidiary object for each function in the
-# collection:
-#    cof1 = co.create(f1 [, arg1, arg2, ...]) # [] means optional,
-#    cof2 = co.create(f2 [, arg1, arg2, ...]) #... not list
-#    cof3 = co.create(f3 [, arg1, arg2, ...])
-# etc.  The functions need not be distinct; 'create'ing the same
-# function multiple times gives you independent instances of the
-# function.
-#
-# To start the coroutines running, use co.tran on one of the create'd
-# functions; e.g., co.tran(cof2).  The routine that first executes
-# co.tran is called the "main coroutine".  It's special in several
-# respects:  it existed before you created the Coroutine object; if any of
-# the create'd coroutines exits (does a return, or suffers an unhandled
-# exception), EarlyExit error is raised in the main coroutine; and the
-# co.detach() method transfers control directly to the main coroutine
-# (you can't use co.tran() for this because the main coroutine doesn't
-# have a name ...).
-#
-# Coroutine objects support these methods:
-#
-# handle = .create(func [, arg1, arg2, ...])
-#    Creates a coroutine for an invocation of func(arg1, arg2, ...),
-#    and returns a handle ("name") for the coroutine so created.  The
-#    handle can be used as the target in a subsequent .tran().
-#
-# .tran(target, data=None)
-#    Transfer control to the create'd coroutine "target", optionally
-#    passing it an arbitrary piece of data. To the coroutine A that does
-#    the .tran, .tran acts like an ordinary function call:  another
-#    coroutine B can .tran back to it later, and if it does A's .tran
-#    returns the 'data' argument passed to B's tran.  E.g.,
-#
-#    in coroutine coA   in coroutine coC    in coroutine coB
-#      x = co.tran(coC)   co.tran(coB)        co.tran(coA,12)
-#      print x # 12
-#
-#    The data-passing feature is taken from Icon, and greatly cuts
-#    the need to use global variables for inter-coroutine communication.
-#
-# .back( data=None )
-#    The same as .tran(invoker, data=None), where 'invoker' is the
-#    coroutine that most recently .tran'ed control to the coroutine
-#    doing the .back.  This is akin to Icon's "&source".
-#
-# .detach( data=None )
-#    The same as .tran(main, data=None), where 'main' is the
-#    (unnameable!) coroutine that started it all.  'main' has all the
-#    rights of any other coroutine:  upon receiving control, it can
-#    .tran to an arbitrary coroutine of its choosing, go .back to
-#    the .detach'er, or .kill the whole thing.
-#
-# .kill()
-#    Destroy all the coroutines, and return control to the main
-#    coroutine.  None of the create'ed coroutines can be resumed after a
-#    .kill().  An EarlyExit exception does a .kill() automatically.  It's
-#    a good idea to .kill() coroutines you're done with, since the
-#    current implementation consumes a thread for each coroutine that
-#    may be resumed.

-#
-# CONDITIONS
-#
-# A condition object is created via
-#   import this_module
-#   your_condition_object = this_module.condition(lock=None)
-#
-# As explained below, a condition object has a lock associated with it,
-# used in the protocol to protect condition data.  You can specify a
-# lock to use in the constructor, else the constructor will allocate
-# an anonymous lock for you.  Specifying a lock explicitly can be useful
-# when more than one condition keys off the same set of shared data.
-#
-# Methods:
-#   .acquire()
-#      acquire the lock associated with the condition
-#   .release()
-#      release the lock associated with the condition
-#   .wait()
-#      block the thread until such time as some other thread does a
-#      .signal or .broadcast on the same condition, and release the
-#      lock associated with the condition.  The lock associated with
-#      the condition MUST be in the acquired state at the time
-#      .wait is invoked.
-#   .signal()
-#      wake up exactly one thread (if any) that previously did a .wait
-#      on the condition; that thread will awaken with the lock associated
-#      with the condition in the acquired state.  If no threads are
-#      .wait'ing, this is a nop.  If more than one thread is .wait'ing on
-#      the condition, any of them may be awakened.
-#   .broadcast()
-#      wake up all threads (if any) that are .wait'ing on the condition;
-#      the threads are woken up serially, each with the lock in the
-#      acquired state, so should .release() as soon as possible.  If no
-#      threads are .wait'ing, this is a nop.
-#
-#      Note that if a thread does a .wait *while* a signal/broadcast is
-#      in progress, it's guaranteeed to block until a subsequent
-#      signal/broadcast.
-#
-#      Secret feature:  `broadcast' actually takes an integer argument,
-#      and will wake up exactly that many waiting threads (or the total
-#      number waiting, if that's less).  Use of this is dubious, though,
-#      and probably won't be supported if this form of condition is
-#      reimplemented in C.

-# + A separate mutex is not needed to guard condition data.  Instead, a
-#   condition object can (must) be .acquire'ed and .release'ed directly.
-#   This eliminates a common error in using POSIX conditions.
-#
-# + Because of implementation difficulties, a POSIX `signal' wakes up
-#   _at least_ one .wait'ing thread.  Race conditions make it difficult
-#   to stop that.  This implementation guarantees to wake up only one,
-#   but you probably shouldn't rely on that.
-#
-# PROTOCOL
-#
-# Condition objects are used to block threads until "some condition" is
-# true.  E.g., a thread may wish to wait until a producer pumps out data
-# for it to consume, or a server may wish to wait until someone requests
-# its services, or perhaps a whole bunch of threads want to wait until a
-# preceding pass over the data is complete.  Early models for conditions
-# relied on some other thread figuring out when a blocked thread's
-# condition was true, and made the other thread responsible both for
-# waking up the blocked thread and guaranteeing that it woke up with all
-# data in a correct state.  This proved to be very delicate in practice,
-# and gave conditions a bad name in some circles.
-#
-# The POSIX model addresses these problems by making a thread responsible
-# for ensuring that its own state is correct when it wakes, and relies
-# on a rigid protocol to make this easy; so long as you stick to the
-# protocol, POSIX conditions are easy to "get right":
-#
-#  A) The thread that's waiting for some arbitrarily-complex condition
-#     (ACC) to become true does:
-#
-#     condition.acquire()
-#     while not (code to evaluate the ACC):
-#           condition.wait()
-#           # That blocks the thread, *and* releases the lock.  When a
-#           # condition.signal() happens, it will wake up some thread that
-#           # did a .wait, *and* acquire the lock again before .wait
-#           # returns.
-#           #
-#           # Because the lock is acquired at this point, the state used
-#           # in evaluating the ACC is frozen, so it's safe to go back &
-#           # reevaluate the ACC.
-#
-#     # At this point, ACC is true, and the thread has the condition
-#     # locked.
-#     # So code here can safely muck with the shared state that
-#     # went into evaluating the ACC -- if it wants to.
-#     # When done mucking with the shared state, do
-#     condition.release()
-#
-#  B) Threads that are mucking with shared state that may affect the
-#     ACC do:
-#
-#     condition.acquire()
-#     # muck with shared state
-#     condition.release()
-#     if it's possible that ACC is true now:
-#         condition.signal() # or .broadcast()
-#
-#     Note:  You may prefer to put the "if" clause before the release().
-#     That's fine, but do note that anyone waiting on the signal will
-#     stay blocked until the release() is done (since acquiring the
-#     condition is part of what .wait() does before it returns).
-#
-# TRICK OF THE TRADE
-#
-# With simpler forms of conditions, it can be impossible to know when
-# a thread that's supposed to do a .wait has actually done it.  But
-# because this form of condition releases a lock as _part_ of doing a
-# wait, the state of that lock can be used to guarantee it.
-#
-# E.g., suppose thread A spawns thread B and later wants to wait for B to
-# complete:
-#
-# In A:                             In B:
-#
-# B_done = condition()              ... do work ...
-# B_done.acquire()                  B_done.acquire(); B_done.release()
-# spawn B                           B_done.signal()
-# ... some time later ...           ... and B exits ...
-# B_done.wait()
-#
-# Because B_done was in the acquire'd state at the time B was spawned,
-# B's attempt to acquire B_done can't succeed until A has done its
-# B_done.wait() (which releases B_done).  So B's B_done.signal() is
-# guaranteed to be seen by the .wait().  Without the lock trick, B
-# may signal before A .waits, and then A would wait forever.
-#
-# BARRIERS
-#
-# A barrier object is created via
-#   import this_module
-#   your_barrier = this_module.barrier(num_threads)
-#
-# Methods:
-#   .enter()
-#      the thread blocks until num_threads threads in all have done
-#      .enter().  Then the num_threads threads that .enter'ed resume,
-#      and the barrier resets to capture the next num_threads threads
-#      that .enter it.
-#
-# EVENTS
-#
-# An event object is created via
-#   import this_module
-#   your_event = this_module.event()
-#
-# An event has two states, `posted' and `cleared'.  An event is
-# created in the cleared state.
-#
-# Methods:
-#
-#   .post()
-#      Put the event in the posted state, and resume all threads
-#      .wait'ing on the event (if any).
-#
-#   .clear()
-#      Put the event in the cleared state.
-#
-#   .is_posted()
-#      Returns 0 if the event is in the cleared state, or 1 if the event
-#      is in the posted state.
-#
-#   .wait()
-#      If the event is in the posted state, returns immediately.
-#      If the event is in the cleared state, blocks the calling thread
-#      until the event is .post'ed by another thread.
-#
-# Note that an event, once posted, remains posted until explicitly
-# cleared.  Relative to conditions, this is both the strength & weakness
-# of events.  It's a strength because the .post'ing thread doesn't have to
-# worry about whether the threads it's trying to communicate with have
-# already done a .wait (a condition .signal is seen only by threads that
-# do a .wait _prior_ to the .signal; a .signal does not persist).  But
-# it's a weakness because .clear'ing an event is error-prone:  it's easy
-# to mistakenly .clear an event before all the threads you intended to
-# see the event get around to .wait'ing on it.  But so long as you don't
-# need to .clear an event, events are easy to use safely.
-#
-# SEMAPHORES
-#
-# A semaphore object is created via
-#   import this_module
-#   your_semaphore = this_module.semaphore(count=1)
-#
-# A semaphore has an integer count associated with it.  The initial value
-# of the count is specified by the optional argument (which defaults to
-# 1) passed to the semaphore constructor.
-#
-# Methods:
-#
-#   .p()
-#      If the semaphore's count is greater than 0, decrements the count
-#      by 1 and returns.
-#      Else if the semaphore's count is 0, blocks the calling thread
-#      until a subsequent .v() increases the count.  When that happens,
-#      the count will be decremented by 1 and the calling thread resumed.
-#
-#   .v()
-#      Increments the semaphore's count by 1, and wakes up a thread (if
-#      any) blocked by a .p().  It's an (detected) error for a .v() to
-#      increase the semaphore's count to a value larger than the initial
-#      count.
-#
-# MULTIPLE-READER SINGLE-WRITER LOCKS
-#
-# A mrsw lock is created via
-#   import this_module
-#   your_mrsw_lock = this_module.mrsw()
-#
-# This kind of lock is often useful with complex shared data structures.
-# The object lets any number of "readers" proceed, so long as no thread
-# wishes to "write".  When a (one or more) thread declares its intention
-# to "write" (e.g., to update a shared structure), all current readers
-# are allowed to finish, and then a writer gets exclusive access; all
-# other readers & writers are blocked until the current writer completes.
-# Finally, if some thread is waiting to write and another is waiting to
-# read, the writer takes precedence.
-#
-# Methods:
-#
-#   .read_in()
-#      If no thread is writing or waiting to write, returns immediately.
-#      Else blocks until no thread is writing or waiting to write.  So
-#      long as some thread has completed a .read_in but not a .read_out,
-#      writers are blocked.
-#
-#   .read_out()
-#      Use sometime after a .read_in to declare that the thread is done
-#      reading.  When all threads complete reading, a writer can proceed.
-#
-#   .write_in()
-#      If no thread is writing (has completed a .write_in, but hasn't yet
-#      done a .write_out) or reading (similarly), returns immediately.
-#      Else blocks the calling thread, and threads waiting to read, until
-#      the current writer completes writing or all the current readers
-#      complete reading; if then more than one thread is waiting to
-#      write, one of them is allowed to proceed, but which one is not
-#      specified.
-#
-#   .write_out()
-#      Use sometime after a .write_in to declare that the thread is done
-#      writing.  Then if some other thread is waiting to write, it's
-#      allowed to proceed.  Else all threads (if any) waiting to read are
-#      allowed to proceed.
-#
-#   .write_to_read()
-#      Use instead of a .write_in to declare that the thread is done
-#      writing but wants to continue reading without other writers
-#      intervening.  If there are other threads waiting to write, they
-#      are allowed to proceed only if the current thread calls
-#      .read_out; threads waiting to read are only allowed to proceed
-#      if there are are no threads waiting to write.  (This is a
-#      weakness of the interface!)

-Installing Tix.py
-----------------
-
-0) To use Tix.py, you need Tcl/Tk (V8.3.3), Tix (V8.1.1) and Python (V2.1.1).
-   Tix.py has been written and tested on a Intel Pentium running RH Linux 5.2
-   and Mandrake Linux 7.0 and Windows with the above mentioned packages.
-
-   Older versions, e.g. Tix 4.1 and Tk 8.0, might also work.
-
-   There is nothing OS-specific in Tix.py itself so it should work on
-   any machine with Tix and Python installed. You can get Tcl and Tk
-   from http://dev.scriptics.com and Tix from http://tix.sourceforge.net.
-
-1) Build and install Tcl/Tk 8.3. Build and install Tix 8.1.
-   Ensure that Tix is properly installed by running tixwish and executing
-   the demo programs. Under Unix, use the --enable-shared configure option
-   for all three. We recommend tcl8.3.3 for this release of Tix.py.
-
-2a) If you have a distribution like ActiveState with a tcl subdirectory
-   of $PYTHONHOME, which contains the directories tcl8.3 and tk8.3,
-   make a directory tix8.1 as well. Recursively copy the files from
-   <tix>/library to $PYTHONHOME/lib/tix8.1, and copy the dynamic library
-   (tix8183.dll or libtix8.1.8.3.so) to the same place as the tcl dynamic
-   libraries  ($PYTHONHOME/Dlls or lib/python-2.1/lib-dynload). In this
-   case you are all installed, and you can skip to the end.
-
-2b) Modify Modules/Setup.dist and setup.py to change the version of the 
-   tix library from tix4.1.8.0 to tix8.1.8.3
-   These modified files can be used for Tkinter with or without Tix.
-   
-3) The default is to build dynamically, and use the Tcl 'package require'.
-   To build statically, modify the Modules/Setup file to link in the Tix 
-   library according to the comments in the file. On Linux this looks like:
-
-# *** Always uncomment this (leave the leading underscore in!):
-_tkinter _tkinter.c tkappinit.c -DWITH_APPINIT \
-# *** Uncomment and edit to reflect where your Tcl/Tk libraries are:
-	-L/usr/local/lib \
-# *** Uncomment and edit to reflect where your Tcl/Tk headers are:
-	-I/usr/local/include \
-# *** Uncomment and edit to reflect where your X11 header files are:
-	-I/usr/X11R6/include \
-# *** Or uncomment this for Solaris:
-#	-I/usr/openwin/include \
-# *** Uncomment and edit for BLT extension only:
-#	-DWITH_BLT -I/usr/local/blt/blt8.0-unoff/include -lBLT8.0 \
-# *** Uncomment and edit for PIL (TkImaging) extension only:
-#     (See http://www.pythonware.com/products/pil/ for more info)
-#	-DWITH_PIL -I../Extensions/Imaging/libImaging  tkImaging.c \
-# *** Uncomment and edit for TOGL extension only:
-#	-DWITH_TOGL togl.c \
-# *** Uncomment and edit for Tix extension only:
-	-DWITH_TIX -ltix8.1.8.3 \
-# *** Uncomment and edit to reflect your Tcl/Tk versions:
-	-ltk8.3 -ltcl8.3 \
-# *** Uncomment and edit to reflect where your X11 libraries are:
-	-L/usr/X11R6/lib \
-# *** Or uncomment this for Solaris:
-#	-L/usr/openwin/lib \
-# *** Uncomment these for TOGL extension only:
-#	-lGL -lGLU -lXext -lXmu \
-# *** Uncomment for AIX:
-#	-lld \
-# *** Always uncomment this; X11 libraries to link with:
-	-lX11
-
-4) Rebuild Python and reinstall.
-
-You should now have a working Tix implementation in Python. To see if all
-is as it should be, run the 'tixwidgets.py' script in the Demo/tix directory.
-Under X windows, do
-	/usr/local/bin/python Demo/tix/tixwidgets.py
-
-If this does not work, you may need to tell python where to find
-the Tcl, Tk and Tix library files. This is done by setting the
-TCL_LIBRARY, TK_LIBRARY and TIX_LIBRARY environment variables. Try this:
-
-	env 	TCL_LIBRARY=/usr/local/lib/tcl8.3 \
-		TK_LIBRARY=/usr/local/lib/tk8.3 \
-		TIX_LIBRARY=/usr/local/lib/tix8.1 \
-		/usr/local/bin/python Demo/tix/tixwidgets.py
-
-
-If you find any bugs or have suggestions for improvement, please report them
-via http://tix.sourceforge.net

-About Tix.py
------------
-
-Tix.py is based on an idea of Jean-Marc Lugrin (lugrin@ms.com) who wrote
-pytix (another Python-Tix marriage). Tix widgets are an attractive and
-useful extension to Tk. See http://tix.sourceforge.net
-for more details about Tix and how to get it.
-
-Features:
-	1) It is almost complete.
-	2) Tix widgets are represented by classes in Python. Sub-widgets
-	   are members of the mega-widget class. For example, if a
-	   particular TixWidget (e.g. ScrolledText) has an embedded widget
-	   (Text in this case), it is possible to call the methods of the
-	   child directly.
-	3) The members of the class are created automatically. In the case
-	   of widgets like ButtonBox, the members are added dynamically.

-    Hi,
-
-    I have implemented a new image type called "compound". It allows you
-    to glue together a bunch of bitmaps, images and text strings together
-    to form a bigger image. Then you can use this image with widgets that
-    support the -image option. For example, you can display a text string string
-    together with a bitmap, at the same time, inside a TK button widget.

-Hi,
-
-I have implemented a new image type called "compound". It allows you
-to glue together a bunch of bitmaps, images and text strings together
-to form a bigger image. Then you can use this image with widgets that
-support the -image option. For example, you can display a text string string
-together with a bitmap, at the same time, inside a TK button widget.

-Date: Fri, 23 Jan 1998 12:18:05 -0500 (EST)

-  Not too long ago (last week maybe?) someone posted a request
-for an example of a paint program using Tkinter. Try as I might
-I can't seem to find it in the archive, so i'll just post mine
-here and hope that the person who requested it sees this!
-
-  All this does is put up a canvas and draw a smooth black line
-whenever you have the mouse button down, but hopefully it will
-be enough to start with.. It would be easy enough to add some
-options like other shapes or colors...

-    position(card) -- move the card to its proper (x, y) position
-
-        The default position() method places all cards at the stack's
-        own (x, y) position.
-
-    userclickhandler(), userdoubleclickhandler() -- called to do
-    subclass specific things on single and double clicks
-
-        The default user (single) click handler shows the top card
-        face up.  The default user double click handler calls the user
-        single click handler.
-
-    usermovehandler(cards) -- called to complete a subpile move
-
-        The default user move handler moves all moved cards back to
-        their original position (by calling the position() method).
-
-    Private methods:
-
-    clickhandler(event), doubleclickhandler(event),
-    motionhandler(event), releasehandler(event) -- event handlers
-
-        The default event handlers turn the top card of the stack with
-        its face up on a (single or double) click, and also support
-        moving a subpile around.
-

-#       The way to think about this is that each radio button menu
-#       controls a different variable -- clicking on one of the
-#       mutually exclusive choices in a radiobutton assigns some value
-#       to an application variable you provide. When you define a

-
-Subclasses of :class:`Command` must define the following methods.
-
-.. method:: Command.initialize_options()
-
-   Set default values for all the options that this command supports.  Note that
-   these defaults may be overridden by other commands, by the setup script, by
-   config files, or by the command-line.  Thus, this is not the place to code
-   dependencies between options; generally, :meth:`initialize_options`
-   implementations are just a bunch of ``self.foo = None`` assignments.
-
-
-.. method:: Command.finalize_options()
-
-   Set final values for all the options that this command supports. This is
-   always called as late as possible, ie.  after any option assignments from the
-   command-line or from other commands have been done.  Thus, this is the place
-   to to code option dependencies: if *foo* depends on *bar*, then it is safe to
-   set *foo* from *bar* as long as *foo* still has the same value it was
-   assigned in :meth:`initialize_options`.
-
-
-.. method:: Command.run()
-
-   A command's raison d'etre: carry out the action it exists to perform, controlled
-   by the options initialized in :meth:`initialize_options`, customized by other
-   commands, the setup script, the command-line, and config files, and finalized in
-   :meth:`finalize_options`.  All terminal output and filesystem interaction should

-
-   *sub_commands* formalizes the notion of a "family" of commands,
-   e.g. ``install`` as the parent with sub-commands ``install_lib``,
-   ``install_headers``, etc.  The parent of a family of commands defines
-   *sub_commands* as a class attribute; it's a list of 2-tuples ``(command_name,
-   predicate)``, with *command_name* a string and *predicate* a function, a
-   string or ``None``.  *predicate* is a method of the parent command that
-   determines whether the corresponding command is applicable in the current
-   situation.  (E.g. we ``install_headers`` is only applicable if we have any C
-   header files to install.)  If *predicate* is ``None``, that command is always
-   applicable.
-
-   *sub_commands* is usually defined at the *end* of a class, because
-   predicates can be methods of the class, so they must already have been
-   defined.  The canonical example is the :command:`install` command.

-The Global Interpreter Lock (GIL) is often seen as a hindrance to Python's
+The :term:`global interpreter lock` (GIL) is often seen as a hindrance to Python's
 deployment on high-end multiprocessor server machines, because a multi-threaded
 Python program effectively only uses one CPU, due to the insistence that
 (almost) all Python code can only run while the GIL is held.
 
 Back in the days of Python 1.5, Greg Stein actually implemented a comprehensive
 patch set (the "free threading" patches) that removed the GIL and replaced it
-with fine-grained locking.  Unfortunately, even on Windows (where locks are very
-efficient) this ran ordinary Python code about twice as slow as the interpreter
-using the GIL.  On Linux the performance loss was even worse because pthread
-locks aren't as efficient.
-
-Since then, the idea of getting rid of the GIL has occasionally come up but
-nobody has found a way to deal with the expected slowdown, and users who don't
-use threads would not be happy if their code ran at half at the speed.  Greg's
-free threading patch set has not been kept up-to-date for later Python versions.
+with fine-grained locking.  Adam Olsen recently did a similar experiment
+in his `python-safethread <http://code.google.com/p/python-safethread/>`_
+project.  Unfortunately, both experiments exhibited a sharp drop in single-thread
+performance (at least 30% slower), due to the amount of fine-grained locking
+necessary to compensate for the removal of the GIL.
 
 This doesn't mean that you can't make good use of Python on multi-CPU machines!
 You just have to be creative with dividing the work up between multiple
-*processes* rather than multiple *threads*.  Judicious use of C extensions will

 It has been suggested that the GIL should be a per-interpreter-state lock rather
 than truly global; interpreters then wouldn't be able to share objects.

+Using logging in multiple modules
+---------------------------------
+
+Multiple calls to ``logging.getLogger('someLogger')`` return a reference to the
+same logger object.  This is true not only within the same module, but also
+across modules as long as it is in the same Python interpreter process.  It is
+true for references to the same object; additionally, application code can
+define and configure a parent logger in one module and create (but not
+configure) a child logger in a separate module, and all logger calls to the
+child will pass up to the parent.  Here is a main module::
+
+    import logging
+    import auxiliary_module
+
+    # create logger with 'spam_application'
+    logger = logging.getLogger('spam_application')
+    logger.setLevel(logging.DEBUG)
+    # create file handler which logs even debug messages
+    fh = logging.FileHandler('spam.log')
+    fh.setLevel(logging.DEBUG)
+    # create console handler with a higher log level
+    ch = logging.StreamHandler()
+    ch.setLevel(logging.ERROR)
+    # create formatter and add it to the handlers
+    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
+    fh.setFormatter(formatter)
+    ch.setFormatter(formatter)
+    # add the handlers to the logger

+    logger.info('calling auxiliary_module.some_function()')
+    auxiliary_module.some_function()
+    logger.info('done with auxiliary_module.some_function()')
+
+Here is the auxiliary module::
+
+    import logging
+
+    # create logger
+    module_logger = logging.getLogger('spam_application.auxiliary')
+
+    class Auxiliary:
+        def __init__(self):

+Multiple handlers and formatters
+--------------------------------
+
+Loggers are plain Python objects.  The :func:`addHandler` method has no minimum
+or maximum quota for the number of handlers you may add.  Sometimes it will be
+beneficial for an application to log all messages of all severities to a text
+file while simultaneously logging errors or above to the console.  To set this
+up, simply configure the appropriate handlers.  The logging calls in the
+application code will remain unchanged.  Here is a slight modification to the
+previous simple module-based configuration example::
+
+    import logging
+
+    logger = logging.getLogger('simple_example')
+    logger.setLevel(logging.DEBUG)
+    # create file handler which logs even debug messages
+    fh = logging.FileHandler('spam.log')
+    fh.setLevel(logging.DEBUG)
+    # create console handler with a higher log level
+    ch = logging.StreamHandler()
+    ch.setLevel(logging.ERROR)
+    # create formatter and add it to the handlers
+    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
+    ch.setFormatter(formatter)
+    fh.setFormatter(formatter)
+    # add the handlers to logger
+    logger.addHandler(ch)
+    logger.addHandler(fh)
+
+    # 'application' code
+    logger.debug('debug message')
+    logger.info('info message')
+    logger.warn('warn message')
+    logger.error('error message')
+    logger.critical('critical message')
+
+Notice that the 'application' code does not care about multiple handlers.  All
+that changed was the addition and configuration of a new handler named *fh*.
+
+The ability to create new handlers with higher- or lower-severity filters can be
+very helpful when writing and testing an application.  Instead of using many
+``print`` statements for debugging, use ``logger.debug``: Unlike the print
+statements, which you will have to delete or comment out later, the logger.debug
+statements can remain intact in the source code and remain dormant until you
+need them again.  At that time, the only change that needs to happen is to
+modify the severity level of the logger and/or handler to debug.
+
+.. _multiple-destinations:
+
+Logging to multiple destinations
+--------------------------------
+
+Let's say you want to log to console and file with different message formats and
+in differing circumstances. Say you want to log messages with levels of DEBUG
+and higher to file, and those messages at level INFO and higher to the console.
+Let's also assume that the file should contain timestamps, but the console
+messages should not. Here's how you can achieve this::
+
+   import logging
+
+   # set up logging to file - see previous section for more details
+   logging.basicConfig(level=logging.DEBUG,
+                       format='%(asctime)s %(name)-12s %(levelname)-8s %(message)s',
+                       datefmt='%m-%d %H:%M',
+                       filename='/temp/myapp.log',
+                       filemode='w')
+   # define a Handler which writes INFO messages or higher to the sys.stderr
+   console = logging.StreamHandler()
+   console.setLevel(logging.INFO)
+   # set a format which is simpler for console use
+   formatter = logging.Formatter('%(name)-12s: %(levelname)-8s %(message)s')
+   # tell the handler to use this format
+   console.setFormatter(formatter)
+   # add the handler to the root logger
+   logging.getLogger('').addHandler(console)
+
+   # Now, we can log to the root logger, or any other logger. First the root...
+   logging.info('Jackdaws love my big sphinx of quartz.')
+
+   # Now, define a couple of other loggers which might represent areas in your
+   # application:
+
+   logger1 = logging.getLogger('myapp.area1')
+   logger2 = logging.getLogger('myapp.area2')
+
+   logger1.debug('Quick zephyrs blow, vexing daft Jim.')
+   logger1.info('How quickly daft jumping zebras vex.')
+   logger2.warning('Jail zesty vixen who grabbed pay from quack.')
+   logger2.error('The five boxing wizards jump quickly.')
+
+When you run this, on the console you will see ::
+
+   root        : INFO     Jackdaws love my big sphinx of quartz.
+   myapp.area1 : INFO     How quickly daft jumping zebras vex.
+   myapp.area2 : WARNING  Jail zesty vixen who grabbed pay from quack.
+   myapp.area2 : ERROR    The five boxing wizards jump quickly.
+
+and in the file you will see something like ::
+
+   10-22 22:19 root         INFO     Jackdaws love my big sphinx of quartz.
+   10-22 22:19 myapp.area1  DEBUG    Quick zephyrs blow, vexing daft Jim.
+   10-22 22:19 myapp.area1  INFO     How quickly daft jumping zebras vex.
+   10-22 22:19 myapp.area2  WARNING  Jail zesty vixen who grabbed pay from quack.
+   10-22 22:19 myapp.area2  ERROR    The five boxing wizards jump quickly.
+
+As you can see, the DEBUG message only shows up in the file. The other messages
+are sent to both destinations.
+
+This example uses console and file handlers, but you can use any number and
+combination of handlers you choose.
+
+
+Configuration server example
+----------------------------
+
+Here is an example of a module using the logging configuration server::
+
+    import logging
+    import logging.config
+    import time
+    import os
+
+    # read initial config file
+    logging.config.fileConfig('logging.conf')
+
+    # create and start listener on port 9999
+    t = logging.config.listen(9999)
+    t.start()
+
+    logger = logging.getLogger('simpleExample')
+
+    try:
+        # loop through logging calls to see the difference
+        # new configurations make, until Ctrl+C is pressed
+        while True:
+            logger.debug('debug message')
+            logger.info('info message')
+            logger.warn('warn message')
+            logger.error('error message')
+            logger.critical('critical message')
+            time.sleep(5)
+    except KeyboardInterrupt:
+        # cleanup
+        logging.config.stopListening()
+        t.join()
+
+And here is a script that takes a filename and sends that file to the server,
+properly preceded with the binary-encoded length, as the new logging
+configuration::
+
+    #!/usr/bin/env python
+    import socket, sys, struct
+
+    with open(sys.argv[1], 'rb') as f:
+        data_to_send = f.read()
+
+    HOST = 'localhost'
+    PORT = 9999
+    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+    print('connecting...')
+    s.connect((HOST, PORT))
+    print('sending config...')
+    s.send(struct.pack('>L', len(data_to_send)))
+    s.send(data_to_send)
+    s.close()
+    print('complete')
+
+
+Dealing with handlers that block
+--------------------------------
+
+.. currentmodule:: logging.handlers
+
+Sometimes you have to get your logging handlers to do their work without
+blocking the thread you’re logging from. This is common in Web applications,
+though of course it also occurs in other scenarios.
+
+A common culprit which demonstrates sluggish behaviour is the
+:class:`SMTPHandler`: sending emails can take a long time, for a
+number of reasons outside the developer’s control (for example, a poorly
+performing mail or network infrastructure). But almost any network-based
+handler can block: Even a :class:`SocketHandler` operation may do a
+DNS query under the hood which is too slow (and this query can be deep in the
+socket library code, below the Python layer, and outside your control).
+
+One solution is to use a two-part approach. For the first part, attach only a
+:class:`QueueHandler` to those loggers which are accessed from
+performance-critical threads. They simply write to their queue, which can be
+sized to a large enough capacity or initialized with no upper bound to their
+size. The write to the queue will typically be accepted quickly, though you
+will probably need to catch the :exc:`queue.Full` exception as a precaution
+in your code. If you are a library developer who has performance-critical
+threads in their code, be sure to document this (together with a suggestion to
+attach only ``QueueHandlers`` to your loggers) for the benefit of other
+developers who will use your code.
+
+The second part of the solution is :class:`QueueListener`, which has been
+designed as the counterpart to :class:`QueueHandler`.  A
+:class:`QueueListener` is very simple: it’s passed a queue and some handlers,
+and it fires up an internal thread which listens to its queue for LogRecords
+sent from ``QueueHandlers`` (or any other source of ``LogRecords``, for that
+matter). The ``LogRecords`` are removed from the queue and passed to the
+handlers for processing.
+
+The advantage of having a separate :class:`QueueListener` class is that you
+can use the same instance to service multiple ``QueueHandlers``. This is more
+resource-friendly than, say, having threaded versions of the existing handler
+classes, which would eat up one thread per handler for no particular benefit.
+
+An example of using these two classes follows (imports omitted)::
+
+    que = queue.Queue(-1) # no limit on size
+    queue_handler = QueueHandler(que)
+    handler = logging.StreamHandler()
+    listener = QueueListener(que, handler)
+    root = logging.getLogger()
+    root.addHandler(queue_handler)
+    formatter = logging.Formatter('%(threadName)s: %(message)s')
+    handler.setFormatter(formatter)
+    listener.start()
+    # The log output will display the thread which generated
+    # the event (the main thread) rather than the internal
+    # thread which monitors the internal queue. This is what
+    # you want to happen.
+    root.warning('Look out!')
+    listener.stop()
+
+which, when run, will produce::
+
+    MainThread: Look out!
+
+
+.. _network-logging:
+
+Sending and receiving logging events across a network
+-----------------------------------------------------
+
+Let's say you want to send logging events across a network, and handle them at
+the receiving end. A simple way of doing this is attaching a
+:class:`SocketHandler` instance to the root logger at the sending end::
+
+   import logging, logging.handlers
+
+   rootLogger = logging.getLogger('')
+   rootLogger.setLevel(logging.DEBUG)
+   socketHandler = logging.handlers.SocketHandler('localhost',
+                       logging.handlers.DEFAULT_TCP_LOGGING_PORT)
+   # don't bother with a formatter, since a socket handler sends the event as
+   # an unformatted pickle
+   rootLogger.addHandler(socketHandler)
+
+   # Now, we can log to the root logger, or any other logger. First the root...
+   logging.info('Jackdaws love my big sphinx of quartz.')
+
+   # Now, define a couple of other loggers which might represent areas in your
+   # application:
+
+   logger1 = logging.getLogger('myapp.area1')
+   logger2 = logging.getLogger('myapp.area2')
+
+   logger1.debug('Quick zephyrs blow, vexing daft Jim.')
+   logger1.info('How quickly daft jumping zebras vex.')
+   logger2.warning('Jail zesty vixen who grabbed pay from quack.')
+   logger2.error('The five boxing wizards jump quickly.')
+
+At the receiving end, you can set up a receiver using the :mod:`socketserver`
+module. Here is a basic working example::
+
+   import pickle
+   import logging
+   import logging.handlers
+   import socketserver
+   import struct
+
+
+   class LogRecordStreamHandler(socketserver.StreamRequestHandler):
+       """Handler for a streaming logging request.
+
+       This basically logs the record using whatever logging policy is
+       configured locally.
+       """
+
+       def handle(self):
+           """
+           Handle multiple requests - each expected to be a 4-byte length,
+           followed by the LogRecord in pickle format. Logs the record
+           according to whatever policy is configured locally.
+           """
+           while True:
+               chunk = self.connection.recv(4)
+               if len(chunk) < 4:
+                   break
+               slen = struct.unpack('>L', chunk)[0]
+               chunk = self.connection.recv(slen)
+               while len(chunk) < slen:
+                   chunk = chunk + self.connection.recv(slen - len(chunk))
+               obj = self.unPickle(chunk)

+       def unPickle(self, data):
+           return pickle.loads(data)
+
+       def handleLogRecord(self, record):
+           # if a name is specified, we use the named logger rather than the one
+           # implied by the record.
+           if self.server.logname is not None:
+               name = self.server.logname
+           else:
+               name = record.name
+           logger = logging.getLogger(name)
+           # N.B. EVERY record gets logged. This is because Logger.handle
+           # is normally called AFTER logger-level filtering. If you want
+           # to do filtering, do it at the client end to save wasting
+           # cycles and network bandwidth!
+           logger.handle(record)
+
+   class LogRecordSocketReceiver(socketserver.ThreadingTCPServer):
+       """
+       Simple TCP socket-based logging receiver suitable for testing.

+
+Note that there are some security issues with pickle in some scenarios. If
+these affect you, you can use an alternative serialization scheme by overriding
+the :meth:`makePickle` method and implementing your alternative there, as
+well as adapting the above script to use your alternative serialization.
+
+
+.. _context-info:
+
+Adding contextual information to your logging output
+----------------------------------------------------
+
+Sometimes you want logging output to contain contextual information in
+addition to the parameters passed to the logging call. For example, in a
+networked application, it may be desirable to log client-specific information
+in the log (e.g. remote client's username, or IP address). Although you could
+use the *extra* parameter to achieve this, it's not always convenient to pass
+the information in this way. While it might be tempting to create
+:class:`Logger` instances on a per-connection basis, this is not a good idea
+because these instances are not garbage collected. While this is not a problem
+in practice, when the number of :class:`Logger` instances is dependent on the
+level of granularity you want to use in logging an application, it could
+be hard to manage if the number of :class:`Logger` instances becomes
+effectively unbounded.
+
+
+Using LoggerAdapters to impart contextual information
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+An easy way in which you can pass contextual information to be output along
+with logging event information is to use the :class:`LoggerAdapter` class.
+This class is designed to look like a :class:`Logger`, so that you can call
+:meth:`debug`, :meth:`info`, :meth:`warning`, :meth:`error`,
+:meth:`exception`, :meth:`critical` and :meth:`log`. These methods have the
+same signatures as their counterparts in :class:`Logger`, so you can use the
+two types of instances interchangeably.
+
+When you create an instance of :class:`LoggerAdapter`, you pass it a
+:class:`Logger` instance and a dict-like object which contains your contextual
+information. When you call one of the logging methods on an instance of
+:class:`LoggerAdapter`, it delegates the call to the underlying instance of
+:class:`Logger` passed to its constructor, and arranges to pass the contextual
+information in the delegated call. Here's a snippet from the code of
+:class:`LoggerAdapter`::
+
+    def debug(self, msg, *args, **kwargs):
+        """
+        Delegate a debug call to the underlying logger, after adding
+        contextual information from this adapter instance.
+        """
+        msg, kwargs = self.process(msg, kwargs)
+        self.logger.debug(msg, *args, **kwargs)
+
+The :meth:`process` method of :class:`LoggerAdapter` is where the contextual
+information is added to the logging output. It's passed the message and
+keyword arguments of the logging call, and it passes back (potentially)
+modified versions of these to use in the call to the underlying logger. The
+default implementation of this method leaves the message alone, but inserts
+an 'extra' key in the keyword argument whose value is the dict-like object
+passed to the constructor. Of course, if you had passed an 'extra' keyword
+argument in the call to the adapter, it will be silently overwritten.
+
+The advantage of using 'extra' is that the values in the dict-like object are
+merged into the :class:`LogRecord` instance's __dict__, allowing you to use
+customized strings with your :class:`Formatter` instances which know about
+the keys of the dict-like object. If you need a different method, e.g. if you
+want to prepend or append the contextual information to the message string,
+you just need to subclass :class:`LoggerAdapter` and override :meth:`process`
+to do what you need. Here's an example script which uses this class, which
+also illustrates what dict-like behaviour is needed from an arbitrary
+'dict-like' object for use in the constructor::
+
+   import logging
+
+   class ConnInfo:
+       """
+       An example class which shows how an arbitrary class can be used as
+       the 'extra' context information repository passed to a LoggerAdapter.
+       """
+
+       def __getitem__(self, name):
+           """
+           To allow this instance to look like a dict.
+           """
+           from random import choice
+           if name == 'ip':
+               result = choice(['127.0.0.1', '192.168.0.1'])
+           elif name == 'user':
+               result = choice(['jim', 'fred', 'sheila'])
+           else:
+               result = self.__dict__.get(name, '?')
+           return result
+
+       def __iter__(self):
+           """
+           To allow iteration over keys, which will be merged into
+           the LogRecord dict before formatting and output.
+           """
+           keys = ['ip', 'user']
+           keys.extend(self.__dict__.keys())
+           return keys.__iter__()
+
+   if __name__ == '__main__':
+       from random import choice
+       levels = (logging.DEBUG, logging.INFO, logging.WARNING, logging.ERROR, logging.CRITICAL)
+       a1 = logging.LoggerAdapter(logging.getLogger('a.b.c'),
+                                  { 'ip' : '123.231.231.123', 'user' : 'sheila' })
+       logging.basicConfig(level=logging.DEBUG,
+                           format='%(asctime)-15s %(name)-5s %(levelname)-8s IP: %(ip)-15s User: %(user)-8s %(message)s')
+       a1.debug('A debug message')
+       a1.info('An info message with %s', 'some parameters')
+       a2 = logging.LoggerAdapter(logging.getLogger('d.e.f'), ConnInfo())
+       for x in range(10):
+           lvl = choice(levels)
+           lvlname = logging.getLevelName(lvl)
+           a2.log(lvl, 'A message at %s level with %d %s', lvlname, 2, 'parameters')
+
+When this script is run, the output should look something like this::

+.. _filters-contextual:
+
+Using Filters to impart contextual information
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You can also add contextual information to log output using a user-defined
+:class:`Filter`. ``Filter`` instances are allowed to modify the ``LogRecords``
+passed to them, including adding additional attributes which can then be output
+using a suitable format string, or if needed a custom :class:`Formatter`.
+
+For example in a web application, the request being processed (or at least,
+the interesting parts of it) can be stored in a threadlocal
+(:class:`threading.local`) variable, and then accessed from a ``Filter`` to
+add, say, information from the request - say, the remote IP address and remote
+user's username - to the ``LogRecord``, using the attribute names 'ip' and
+'user' as in the ``LoggerAdapter`` example above. In that case, the same format
+string can be used to get similar output to that shown above. Here's an example
+script::
+
+    import logging
+    from random import choice
+
+    class ContextFilter(logging.Filter):
+        """
+        This is a filter which injects contextual information into the log.
+
+        Rather than use actual contextual information, we just use random
+        data in this demo.
+        """
+
+        USERS = ['jim', 'fred', 'sheila']
+        IPS = ['123.231.231.123', '127.0.0.1', '192.168.0.1']
+
+        def filter(self, record):
+
+            record.ip = choice(ContextFilter.IPS)
+            record.user = choice(ContextFilter.USERS)
+            return True
+
+    if __name__ == '__main__':
+       levels = (logging.DEBUG, logging.INFO, logging.WARNING, logging.ERROR, logging.CRITICAL)
+       logging.basicConfig(level=logging.DEBUG,
+                           format='%(asctime)-15s %(name)-5s %(levelname)-8s IP: %(ip)-15s User: %(user)-8s %(message)s')
+       a1 = logging.getLogger('a.b.c')
+       a2 = logging.getLogger('d.e.f')
+
+       f = ContextFilter()
+       a1.addFilter(f)
+       a2.addFilter(f)
+       a1.debug('A debug message')
+       a1.info('An info message with %s', 'some parameters')
+       for x in range(10):
+           lvl = choice(levels)
+           lvlname = logging.getLevelName(lvl)
+           a2.log(lvl, 'A message at %s level with %d %s', lvlname, 2, 'parameters')

+.. _multiple-processes:
+
+Logging to a single file from multiple processes
+------------------------------------------------
+
+Although logging is thread-safe, and logging to a single file from multiple
+threads in a single process *is* supported, logging to a single file from
+*multiple processes* is *not* supported, because there is no standard way to
+serialize access to a single file across multiple processes in Python. If you
+need to log to a single file from multiple processes, one way of doing this is
+to have all the processes log to a :class:`SocketHandler`, and have a separate
+process which implements a socket server which reads from the socket and logs
+to file. (If you prefer, you can dedicate one thread in one of the existing
+processes to perform this function.) The following section documents this
+approach in more detail and includes a working socket receiver which can be
+used as a starting point for you to adapt in your own applications.
+
+If you are using a recent version of Python which includes the
+:mod:`multiprocessing` module, you could write your own handler which uses the
+:class:`Lock` class from this module to serialize access to the file from
+your processes. The existing :class:`FileHandler` and subclasses do not make
+use of :mod:`multiprocessing` at present, though they may do so in the future.
+Note that at present, the :mod:`multiprocessing` module does not provide
+working lock functionality on all platforms (see
+http://bugs.python.org/issue3770).
+
+.. currentmodule:: logging.handlers
+
+Alternatively, you can use a ``Queue`` and a :class:`QueueHandler` to send
+all logging events to one of the processes in your multi-process application.
+The following example script demonstrates how you can do this; in the example
+a separate listener process listens for events sent by other processes and logs
+them according to its own logging configuration. Although the example only
+demonstrates one way of doing it (for example, you may want to use a listener
+thread rather than a separate listener process -- the implementation would be
+analogous) it does allow for completely different logging configurations for
+the listener and the other processes in your application, and can be used as
+the basis for code meeting your own specific requirements::
+
+    # You'll need these imports in your own code
+    import logging
+    import logging.handlers
+    import multiprocessing
+
+    # Next two import lines for this demo only
+    from random import choice, random
+    import time
+
+    #
+    # Because you'll want to define the logging configurations for listener and workers, the
+    # listener and worker process functions take a configurer parameter which is a callable
+    # for configuring logging for that process. These functions are also passed the queue,
+    # which they use for communication.
+    #
+    # In practice, you can configure the listener however you want, but note that in this
+    # simple example, the listener does not apply level or filter logic to received records.
+    # In practice, you would probably want to do this logic in the worker processes, to avoid
+    # sending events which would be filtered out between processes.
+    #

+
+This variant shows how you can e.g. apply configuration for particular loggers
+- e.g. the ``foo`` logger has a special handler which stores all events in the
+``foo`` subsystem in a file ``mplog-foo.log``. This will be used by the logging
+machinery in the main process (even though the logging events are generated in
+the worker processes) to direct the messages to the appropriate destinations.
+
+Using file rotation
+-------------------
+
+.. sectionauthor:: Doug Hellmann, Vinay Sajip (changes)
+.. (see <http://blog.doughellmann.com/2007/05/pymotw-logging.html>)
+
+Sometimes you want to let a log file grow to a certain size, then open a new
+file and log to that. You may want to keep a certain number of these files, and
+when that many files have been created, rotate the files so that the number of
+files and the size of the files both remain bounded. For this usage pattern, the
+logging package provides a :class:`RotatingFileHandler`::
+
+   import glob
+   import logging
+   import logging.handlers
+
+   LOG_FILENAME = 'logging_rotatingfile_example.out'
+
+   # Set up a specific logger with our desired output level
+   my_logger = logging.getLogger('MyLogger')
+   my_logger.setLevel(logging.DEBUG)
+
+   # Add the log message handler to the logger
+   handler = logging.handlers.RotatingFileHandler(
+                 LOG_FILENAME, maxBytes=20, backupCount=5)
+
+   my_logger.addHandler(handler)
+
+   # Log some messages
+   for i in range(20):
+       my_logger.debug('i = %d' % i)
+
+   # See what files are created
+   logfiles = glob.glob('%s*' % LOG_FILENAME)
+
+   for filename in logfiles:
+       print(filename)
+
+The result should be 6 separate files, each with part of the log history for the
+application::
+
+   logging_rotatingfile_example.out
+   logging_rotatingfile_example.out.1
+   logging_rotatingfile_example.out.2
+   logging_rotatingfile_example.out.3
+   logging_rotatingfile_example.out.4
+   logging_rotatingfile_example.out.5
+
+The most current file is always :file:`logging_rotatingfile_example.out`,
+and each time it reaches the size limit it is renamed with the suffix
+``.1``. Each of the existing backup files is renamed to increment the suffix
+(``.1`` becomes ``.2``, etc.)  and the ``.6`` file is erased.
+
+Obviously this example sets the log length much much too small as an extreme
+example.  You would want to set *maxBytes* to an appropriate value.
+
+.. _zeromq-handlers:
+
+Subclassing QueueHandler - a ZeroMQ example
+-------------------------------------------
+
+You can use a :class:`QueueHandler` subclass to send messages to other kinds
+of queues, for example a ZeroMQ 'publish' socket. In the example below,the
+socket is created separately and passed to the handler (as its 'queue')::
+
+    import zmq # using pyzmq, the Python binding for ZeroMQ
+    import json # for serializing records portably
+
+    ctx = zmq.Context()
+    sock = zmq.Socket(ctx, zmq.PUB) # or zmq.PUSH, or other suitable value
+    sock.bind('tcp://*:5556') # or wherever
+
+    class ZeroMQSocketHandler(QueueHandler):
+        def enqueue(self, record):
+            data = json.dumps(record.__dict__)
+            self.queue.send(data)
+
+    handler = ZeroMQSocketHandler(sock)
+
+
+Of course there are other ways of organizing this, for example passing in the
+data needed by the handler to create the socket::
+
+    class ZeroMQSocketHandler(QueueHandler):
+        def __init__(self, uri, socktype=zmq.PUB, ctx=None):
+            self.ctx = ctx or zmq.Context()
+            socket = zmq.Socket(self.ctx, socktype)
+            socket.bind(uri)
+            QueueHandler.__init__(self, socket)
+
+        def enqueue(self, record):
+            data = json.dumps(record.__dict__)
+            self.queue.send(data)
+
+        def close(self):
+            self.queue.close()
+
+
+Subclassing QueueListener - a ZeroMQ example
+--------------------------------------------
+
+You can also subclass :class:`QueueListener` to get messages from other kinds
+of queues, for example a ZeroMQ 'subscribe' socket. Here's an example::
+
+    class ZeroMQSocketListener(QueueListener):
+        def __init__(self, uri, *handlers, **kwargs):
+            self.ctx = kwargs.get('ctx') or zmq.Context()
+            socket = zmq.Socket(self.ctx, zmq.SUB)
+            socket.setsockopt(zmq.SUBSCRIBE, '') # subscribe to everything
+            socket.connect(uri)
+
+        def dequeue(self):
+            msg = self.queue.recv()
+            return logging.makeLogRecord(json.loads(msg))

+Basic Logging Tutorial
+----------------------
+
+Logging is a means of tracking events that happen when some software runs. The
+software's developer adds logging calls to their code to indicate that certain
+events have occurred. An event is described by a descriptive message which can
+optionally contain variable data (i.e. data that is potentially different for
+each occurrence of the event). Events also have an importance which the
+developer ascribes to the event; the importance can also be called the *level*
+or *severity*.
+
+When to use logging
+^^^^^^^^^^^^^^^^^^^
+
+Logging provides a set of convenience functions for simple logging usage. These
+are :func:`debug`, :func:`info`, :func:`warning`, :func:`error` and
+:func:`critical`. To determine when to use logging, see the table below, which
+states, for each of a set of common tasks, the best tool to use for it.
+
++-------------------------------------+--------------------------------------+
+| Task you want to perform            | The best tool for the task           |
++=====================================+======================================+
+| Display console output for ordinary | :func:`print`                        |
+| usage of a command line script or   |                                      |
+| program                             |                                      |
++-------------------------------------+--------------------------------------+
+| Report events that occur during     | :func:`logging.info` (or             |
+| normal operation of a program (e.g. | :func:`logging.debug` for very       |
+| for status monitoring or fault      | detailed output for diagnostic       |
+| investigation)                      | purposes)                            |
++-------------------------------------+--------------------------------------+
+| Issue a warning regarding a         | :func:`warnings.warn` in library     |
+| particular runtime event            | code if the issue is avoidable and   |
+|                                     | the client application should be     |
+|                                     | modified to eliminate the warning    |
+|                                     |                                      |
+|                                     | :func:`logging.warning` if there is  |
+|                                     | nothing the client application can do|
+|                                     | about the situation, but the event   |
+|                                     | should still be noted                |
++-------------------------------------+--------------------------------------+
+| Report an error regarding a         | Raise an exception                   |
+| particular runtime event            |                                      |
++-------------------------------------+--------------------------------------+
+| Report suppression of an error      | :func:`logging.error`,               |
+| without raising an exception (e.g.  | :func:`logging.exception` or         |
+| error handler in a long-running     | :func:`logging.critical` as          |
+| server process)                     | appropriate for the specific error   |
+|                                     | and application domain               |
++-------------------------------------+--------------------------------------+
+
+The logging functions are named after the level or severity of the events
+they are used to track. The standard levels and their applicability are
+described below (in increasing order of severity):
+
++--------------+---------------------------------------------+
+| Level        | When it's used                              |
++==============+=============================================+
+| ``DEBUG``    | Detailed information, typically of interest |
+|              | only when diagnosing problems.              |
++--------------+---------------------------------------------+
+| ``INFO``     | Confirmation that things are working as     |
+|              | expected.                                   |
++--------------+---------------------------------------------+
+| ``WARNING``  | An indication that something unexpected     |
+|              | happened, or indicative of some problem in  |
+|              | the near future (e.g. 'disk space low').    |
+|              | The software is still working as expected.  |
++--------------+---------------------------------------------+
+| ``ERROR``    | Due to a more serious problem, the software |
+|              | has not been able to perform some function. |
++--------------+---------------------------------------------+
+| ``CRITICAL`` | A serious error, indicating that the program|
+|              | itself may be unable to continue running.   |
++--------------+---------------------------------------------+
+
+The default level is ``WARNING``, which means that only events of this level
+and above will be tracked, unless the logging package is configured to do
+otherwise.
+
+Events that are tracked can be handled in different ways. The simplest way of
+handling tracked events is to print them to the console. Another common way
+is to write them to a disk file.
+
+
+.. _howto-minimal-example:
+
+A simple example
+^^^^^^^^^^^^^^^^
+
+A very simple example is::
+
+   import logging
+   logging.warning('Watch out!') # will print a message to the console
+   logging.info('I told you so') # will not print anything
+
+If you type these lines into a script and run it, you'll see::
+
+   WARNING:root:Watch out!
+
+printed out on the console. The ``INFO`` message doesn't appear because the
+default level is ``WARNING``. The printed message includes the indication of
+the level and the description of the event provided in the logging call, i.e.
+'Watch out!'. Don't worry about the 'root' part for now: it will be explained
+later. The actual output can be formatted quite flexibly if you need that;
+formatting options will also be explained later.
+
+
+Logging to a file
+^^^^^^^^^^^^^^^^^
+
+A very common situation is that of recording logging events in a file, so let's
+look at that next::
+
+   import logging
+   logging.basicConfig(filename='example.log',level=logging.DEBUG)
+   logging.debug('This message should go to the log file')
+   logging.info('So should this')
+   logging.warning('And this, too')
+
+And now if we open the file and look at what we have, we should find the log
+messages::
+
+   DEBUG:root:This message should go to the log file
+   INFO:root:So should this
+   WARNING:root:And this, too
+
+This example also shows how you can set the logging level which acts as the
+threshold for tracking. In this case, because we set the threshold to
+``DEBUG``, all of the messages were printed.
+
+If you want to set the logging level from a command-line option such as::
+
+   --log=INFO
+
+and you have the value of the parameter passed for ``--log`` in some variable
+*loglevel*, you can use::
+
+   getattr(logging, loglevel.upper())
+
+to get the value which you'll pass to :func:`basicConfig` via the *level*
+argument. You may want to error check any user input value, perhaps as in the
+following example::
+
+   # assuming loglevel is bound to the string value obtained from the
+   # command line argument. Convert to upper case to allow the user to
+   # specify --log=DEBUG or --log=debug
+   numeric_level = getattr(logging, loglevel.upper(), None)
+   if not isinstance(numeric_level, int):
+       raise ValueError('Invalid log level: %s' % loglevel)
+   logging.basicConfig(level=numeric_level, ...)
+
+The call to :func:`basicConfig` should come *before* any calls to :func:`debug`,
+:func:`info` etc. As it's intended as a one-off simple configuration facility,
+only the first call will actually do anything: subsequent calls are effectively
+no-ops.
+
+If you run the above script several times, the messages from successive runs
+are appended to the file *example.log*. If you want each run to start afresh,
+not remembering the messages from earlier runs, you can specify the *filemode*
+argument, by changing the call in the above example to::
+
+   logging.basicConfig(filename='example.log', filemode='w', level=logging.DEBUG)
+
+The output will be the same as before, but the log file is no longer appended
+to, so the messages from earlier runs are lost.
+
+
+Logging from multiple modules
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If your program consists of multiple modules, here's an example of how you
+could organize logging in it::
+
+   # myapp.py
+   import logging
+   import mylib
+
+   def main():
+       logging.basicConfig(filename='myapp.log', level=logging.INFO)
+       logging.info('Started')
+       mylib.do_something()
+       logging.info('Finished')
+
+   if __name__ == '__main__':
+       main()
+
+::
+
+   # mylib.py
+   import logging
+
+   def do_something():
+       logging.info('Doing something')
+
+If you run *myapp.py*, you should see this in *myapp.log*::
+
+   INFO:root:Started
+   INFO:root:Doing something
+   INFO:root:Finished
+
+which is hopefully what you were expecting to see. You can generalize this to
+multiple modules, using the pattern in *mylib.py*. Note that for this simple
+usage pattern, you won't know, by looking in the log file, *where* in your
+application your messages came from, apart from looking at the event
+description. If you want to track the location of your messages, you'll need
+to refer to the documentation beyond the tutorial level -- see
+:ref:`logging-advanced-tutorial`.
+
+
+Logging variable data
+^^^^^^^^^^^^^^^^^^^^^
+
+To log variable data, use a format string for the event description message and
+append the variable data as arguments. For example::
+
+   import logging
+   logging.warning('%s before you %s', 'Look', 'leap!')
+
+will display::
+
+   WARNING:root:Look before you leap!
+
+As you can see, merging of variable data into the event description message
+uses the old, %-style of string formatting. This is for backwards
+compatibility: the logging package pre-dates newer formatting options such as
+:meth:`str.format` and :class:`string.Template`. These newer formatting
+options *are* supported, but exploring them is outside the scope of this
+tutorial.
+
+
+Changing the format of displayed messages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To change the format which is used to display messages, you need to
+specify the format you want to use::
+
+   import logging
+   logging.basicConfig(format='%(levelname)s:%(message)s', level=logging.DEBUG)
+   logging.debug('This message should appear on the console')
+   logging.info('So should this')
+   logging.warning('And this, too')
+
+which would print::
+
+   DEBUG:This message should appear on the console
+   INFO:So should this
+   WARNING:And this, too
+
+Notice that the 'root' which appeared in earlier examples has disappeared. For
+a full set of things that can appear in format strings, you can refer to the
+documentation for :ref:`logrecord-attributes`, but for simple usage, you just
+need the *levelname* (severity), *message* (event description, including
+variable data) and perhaps to display when the event occurred. This is
+described in the next section.
+
+
+Displaying the date/time in messages
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To display the date and time of an event, you would place '%(asctime)s' in
+your format string::
+
+   import logging
+   logging.basicConfig(format='%(asctime)s %(message)s')
+   logging.warning('is when this event was logged.')
+
+which should print something like this::
+
+   2010-12-12 11:41:42,612 is when this event was logged.
+
+The default format for date/time display (shown above) is ISO8601. If you need
+more control over the formatting of the date/time, provide a *datefmt*
+argument to ``basicConfig``, as in this example::
+
+   import logging
+   logging.basicConfig(format='%(asctime)s %(message)s', datefmt='%m/%d/%Y %I:%M:%S %p')
+   logging.warning('is when this event was logged.')
+
+which would display something like this::
+
+   12/12/2010 11:46:36 AM is when this event was logged.
+
+The format of the *datefmt* argument is the same as supported by
+:func:`time.strftime`.
+
+
+Next Steps
+^^^^^^^^^^
+
+That concludes the basic tutorial. It should be enough to get you up and
+running with logging. There's a lot more that the logging package offers, but
+to get the best out of it, you'll need to invest a little more of your time in
+reading the following sections. If you're ready for that, grab some of your
+favourite beverage and carry on.
+
+If your logging needs are simple, then use the above examples to incorporate
+logging into your own scripts, and if you run into problems or don't
+understand something, please post a question on the comp.lang.python Usenet
+group (available at http://groups.google.com/group/comp.lang.python) and you
+should receive help before too long.
+
+Still here? You can carry on reading the next few sections, which provide a
+slightly more advanced/in-depth tutorial than the basic one above. After that,
+you can take a look at the :ref:`logging-cookbook`.
+
+.. _logging-advanced-tutorial:
+
+
+Advanced Logging Tutorial
+-------------------------
+
+The logging library takes a modular approach and offers several categories
+of components: loggers, handlers, filters, and formatters.
+
+* Loggers expose the interface that application code directly uses.
+* Handlers send the log records (created by loggers) to the appropriate
+  destination.
+* Filters provide a finer grained facility for determining which log records
+  to output.
+* Formatters specify the layout of log records in the final output.
+
+Logging is performed by calling methods on instances of the :class:`Logger`
+class (hereafter called :dfn:`loggers`). Each instance has a name, and they are
+conceptually arranged in a namespace hierarchy using dots (periods) as
+separators. For example, a logger named 'scan' is the parent of loggers
+'scan.text', 'scan.html' and 'scan.pdf'. Logger names can be anything you want,
+and indicate the area of an application in which a logged message originates.
+
+A good convention to use when naming loggers is to use a module-level logger,
+in each module which uses logging, named as follows::
+
+   logger = logging.getLogger(__name__)
+
+This means that logger names track the package/module hierarchy, and it's
+intuitively obvious where events are logged just from the logger name.
+
+The root of the hierarchy of loggers is called the root logger. That's the
+logger used by the functions :func:`debug`, :func:`info`, :func:`warning`,
+:func:`error` and :func:`critical`, which just call the same-named method of
+the root logger. The functions and the methods have the same signatures. The
+root logger's name is printed as 'root' in the logged output.
+
+It is, of course, possible to log messages to different destinations. Support
+is included in the package for writing log messages to files, HTTP GET/POST
+locations, email via SMTP, generic sockets, queues, or OS-specific logging
+mechanisms such as syslog or the Windows NT event log. Destinations are served
+by :dfn:`handler` classes. You can create your own log destination class if
+you have special requirements not met by any of the built-in handler classes.
+
+By default, no destination is set for any logging messages. You can specify
+a destination (such as console or file) by using :func:`basicConfig` as in the
+tutorial examples. If you call the functions  :func:`debug`, :func:`info`,
+:func:`warning`, :func:`error` and :func:`critical`, they will check to see
+if no destination is set; and if one is not set, they will set a destination
+of the console (``sys.stderr``) and a default format for the displayed
+message before delegating to the root logger to do the actual message output.
+
+The default format set by :func:`basicConfig` for messages is::
+
+   severity:logger name:message
+
+You can change this by passing a format string to :func:`basicConfig` with the
+*format* keyword argument. For all options regarding how a format string is
+constructed, see :ref:`formatter-objects`.
+
+
+Loggers
+^^^^^^^
+
+:class:`Logger` objects have a threefold job.  First, they expose several
+methods to application code so that applications can log messages at runtime.
+Second, logger objects determine which log messages to act upon based upon
+severity (the default filtering facility) or filter objects.  Third, logger
+objects pass along relevant log messages to all interested log handlers.
+
+The most widely used methods on logger objects fall into two categories:
+configuration and message sending.
+
+These are the most common configuration methods:
+
+* :meth:`Logger.setLevel` specifies the lowest-severity log message a logger
+  will handle, where debug is the lowest built-in severity level and critical
+  is the highest built-in severity.  For example, if the severity level is
+  INFO, the logger will handle only INFO, WARNING, ERROR, and CRITICAL messages
+  and will ignore DEBUG messages.
+
+* :meth:`Logger.addHandler` and :meth:`Logger.removeHandler` add and remove
+  handler objects from the logger object.  Handlers are covered in more detail
+  in :ref:`handler-basic`.
+
+* :meth:`Logger.addFilter` and :meth:`Logger.removeFilter` add and remove filter
+  objects from the logger object.  Filters are covered in more detail in
+  :ref:`filter`.
+
+You don't need to always call these methods on every logger you create. See the
+last two paragraphs in this section.
+
+With the logger object configured, the following methods create log messages:
+
+* :meth:`Logger.debug`, :meth:`Logger.info`, :meth:`Logger.warning`,
+  :meth:`Logger.error`, and :meth:`Logger.critical` all create log records with
+  a message and a level that corresponds to their respective method names. The
+  message is actually a format string, which may contain the standard string
+  substitution syntax of :const:`%s`, :const:`%d`, :const:`%f`, and so on.  The
+  rest of their arguments is a list of objects that correspond with the
+  substitution fields in the message.  With regard to :const:`**kwargs`, the
+  logging methods care only about a keyword of :const:`exc_info` and use it to
+  determine whether to log exception information.
+
+* :meth:`Logger.exception` creates a log message similar to
+  :meth:`Logger.error`.  The difference is that :meth:`Logger.exception` dumps a
+  stack trace along with it.  Call this method only from an exception handler.
+
+* :meth:`Logger.log` takes a log level as an explicit argument.  This is a
+  little more verbose for logging messages than using the log level convenience
+  methods listed above, but this is how to log at custom log levels.
+
+:func:`getLogger` returns a reference to a logger instance with the specified
+name if it is provided, or ``root`` if not.  The names are period-separated
+hierarchical structures.  Multiple calls to :func:`getLogger` with the same name
+will return a reference to the same logger object.  Loggers that are further
+down in the hierarchical list are children of loggers higher up in the list.
+For example, given a logger with a name of ``foo``, loggers with names of
+``foo.bar``, ``foo.bar.baz``, and ``foo.bam`` are all descendants of ``foo``.
+
+Loggers have a concept of *effective level*. If a level is not explicitly set
+on a logger, the level of its parent is used instead as its effective level.
+If the parent has no explicit level set, *its* parent is examined, and so on -
+all ancestors are searched until an explicitly set level is found. The root
+logger always has an explicit level set (``WARNING`` by default). When deciding
+whether to process an event, the effective level of the logger is used to
+determine whether the event is passed to the logger's handlers.
+
+Child loggers propagate messages up to the handlers associated with their
+ancestor loggers. Because of this, it is unnecessary to define and configure
+handlers for all the loggers an application uses. It is sufficient to
+configure handlers for a top-level logger and create child loggers as needed.
+(You can, however, turn off propagation by setting the *propagate*
+attribute of a logger to *False*.)
+
+
+.. _handler-basic:
+
+Handlers
+^^^^^^^^
+
+:class:`~logging.Handler` objects are responsible for dispatching the
+appropriate log messages (based on the log messages' severity) to the handler's
+specified destination.  Logger objects can add zero or more handler objects to
+themselves with an :func:`addHandler` method.  As an example scenario, an
+application may want to send all log messages to a log file, all log messages
+of error or higher to stdout, and all messages of critical to an email address.
+This scenario requires three individual handlers where each handler is
+responsible for sending messages of a specific severity to a specific location.
+
+The standard library includes quite a few handler types (see
+:ref:`useful-handlers`); the tutorials use mainly :class:`StreamHandler` and
+:class:`FileHandler` in its examples.
+
+There are very few methods in a handler for application developers to concern
+themselves with.  The only handler methods that seem relevant for application
+developers who are using the built-in handler objects (that is, not creating
+custom handlers) are the following configuration methods:
+
+* The :meth:`Handler.setLevel` method, just as in logger objects, specifies the
+  lowest severity that will be dispatched to the appropriate destination.  Why
+  are there two :func:`setLevel` methods?  The level set in the logger
+  determines which severity of messages it will pass to its handlers.  The level
+  set in each handler determines which messages that handler will send on.
+
+* :func:`setFormatter` selects a Formatter object for this handler to use.
+
+* :func:`addFilter` and :func:`removeFilter` respectively configure and
+  deconfigure filter objects on handlers.
+
+Application code should not directly instantiate and use instances of
+:class:`Handler`.  Instead, the :class:`Handler` class is a base class that
+defines the interface that all handlers should have and establishes some
+default behavior that child classes can use (or override).
+
+
+Formatters
+^^^^^^^^^^
+
+Formatter objects configure the final order, structure, and contents of the log
+message.  Unlike the base :class:`logging.Handler` class, application code may
+instantiate formatter classes, although you could likely subclass the formatter
+if your application needs special behavior.  The constructor takes three
+optional arguments -- a message format string, a date format string and a style
+indicator.
+
+.. method:: logging.Formatter.__init__(fmt=None, datefmt=None, style='%')
+
+If there is no message format string, the default is to use the
+raw message.  If there is no date format string, the default date format is::
+
+    %Y-%m-%d %H:%M:%S
+
+with the milliseconds tacked on at the end. The ``style`` is one of `%`, '{'
+or '$'. If one of these is not specified, then '%' will be used.
+
+If the ``style`` is '%', the message format string uses
+``%(<dictionary key>)s`` styled string substitution; the possible keys are
+documented in :ref:`logrecord-attributes`. If the style is '{', the message
+format string is assumed to be compatible with :meth:`str.format` (using
+keyword arguments), while if the style is '$' then the message format string
+should conform to what is expected by :meth:`string.Template.substitute`.
+
+.. versionchanged:: 3.2
+   Added the ``style`` parameter.
+
+The following message format string will log the time in a human-readable
+format, the severity of the message, and the contents of the message, in that
+order::
+
+    '%(asctime)s - %(levelname)s - %(message)s'
+
+Formatters use a user-configurable function to convert the creation time of a
+record to a tuple. By default, :func:`time.localtime` is used; to change this
+for a particular formatter instance, set the ``converter`` attribute of the
+instance to a function with the same signature as :func:`time.localtime` or
+:func:`time.gmtime`. To change it for all formatters, for example if you want
+all logging times to be shown in GMT, set the ``converter`` attribute in the
+Formatter class (to ``time.gmtime`` for GMT display).
+
+
+Configuring Logging
+^^^^^^^^^^^^^^^^^^^
+
+.. currentmodule:: logging.config
+
+Programmers can configure logging in three ways:
+
+1. Creating loggers, handlers, and formatters explicitly using Python
+   code that calls the configuration methods listed above.
+2. Creating a logging config file and reading it using the :func:`fileConfig`
+   function.
+3. Creating a dictionary of configuration information and passing it
+   to the :func:`dictConfig` function.
+
+For the reference documentation on the last two options, see
+:ref:`logging-config-api`.  The following example configures a very simple
+logger, a console handler, and a simple formatter using Python code::
+
+    import logging
+
+    # create logger
+    logger = logging.getLogger('simple_example')
+    logger.setLevel(logging.DEBUG)
+
+    # create console handler and set level to debug
+    ch = logging.StreamHandler()
+    ch.setLevel(logging.DEBUG)
+
+    # create formatter
+    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
+
+    # add formatter to ch
+    ch.setFormatter(formatter)
+
+    # add ch to logger
+    logger.addHandler(ch)
+
+    # 'application' code
+    logger.debug('debug message')
+    logger.info('info message')
+    logger.warn('warn message')
+    logger.error('error message')
+    logger.critical('critical message')
+
+Running this module from the command line produces the following output::
+
+    $ python simple_logging_module.py
+    2005-03-19 15:10:26,618 - simple_example - DEBUG - debug message
+    2005-03-19 15:10:26,620 - simple_example - INFO - info message
+    2005-03-19 15:10:26,695 - simple_example - WARNING - warn message
+    2005-03-19 15:10:26,697 - simple_example - ERROR - error message
+    2005-03-19 15:10:26,773 - simple_example - CRITICAL - critical message
+
+The following Python module creates a logger, handler, and formatter nearly
+identical to those in the example listed above, with the only difference being
+the names of the objects::
+
+    import logging
+    import logging.config
+
+    logging.config.fileConfig('logging.conf')
+
+    # create logger
+    logger = logging.getLogger('simpleExample')
+
+    # 'application' code
+    logger.debug('debug message')
+    logger.info('info message')
+    logger.warn('warn message')
+    logger.error('error message')
+    logger.critical('critical message')
+
+Here is the logging.conf file::
+
+    [loggers]
+    keys=root,simpleExample
+
+    [handlers]
+    keys=consoleHandler
+
+    [formatters]
+    keys=simpleFormatter
+
+    [logger_root]
+    level=DEBUG
+    handlers=consoleHandler
+
+    [logger_simpleExample]
+    level=DEBUG
+    handlers=consoleHandler
+    qualname=simpleExample
+    propagate=0
+
+    [handler_consoleHandler]
+    class=StreamHandler
+    level=DEBUG
+    formatter=simpleFormatter
+    args=(sys.stdout,)
+
+    [formatter_simpleFormatter]
+    format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
+    datefmt=
+
+The output is nearly identical to that of the non-config-file-based example::
+
+    $ python simple_logging_config.py
+    2005-03-19 15:38:55,977 - simpleExample - DEBUG - debug message
+    2005-03-19 15:38:55,979 - simpleExample - INFO - info message
+    2005-03-19 15:38:56,054 - simpleExample - WARNING - warn message
+    2005-03-19 15:38:56,055 - simpleExample - ERROR - error message
+    2005-03-19 15:38:56,130 - simpleExample - CRITICAL - critical message
+
+You can see that the config file approach has a few advantages over the Python
+code approach, mainly separation of configuration and code and the ability of
+noncoders to easily modify the logging properties.
+
+.. currentmodule:: logging
+
+Note that the class names referenced in config files need to be either relative
+to the logging module, or absolute values which can be resolved using normal
+import mechanisms. Thus, you could use either
+:class:`~logging.handlers.WatchedFileHandler` (relative to the logging module) or
+``mypackage.mymodule.MyHandler`` (for a class defined in package ``mypackage``
+and module ``mymodule``, where ``mypackage`` is available on the Python import
+path).
+
+In Python 3.2, a new means of configuring logging has been introduced, using
+dictionaries to hold configuration information. This provides a superset of the
+functionality of the config-file-based approach outlined above, and is the
+recommended configuration method for new applications and deployments. Because
+a Python dictionary is used to hold configuration information, and since you
+can populate that dictionary using different means, you have more options for
+configuration. For example, you can use a configuration file in JSON format,
+or, if you have access to YAML processing functionality, a file in YAML
+format, to populate the configuration dictionary. Or, of course, you can
+construct the dictionary in Python code, receive it in pickled form over a
+socket, or use whatever approach makes sense for your application.
+
+Here's an example of the same configuration as above, in YAML format for
+the new dictionary-based approach::
+
+    version: 1
+    formatters:
+      simple:
+        format: format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
+    handlers:
+      console:
+        class: logging.StreamHandler
+        level: DEBUG
+        formatter: simple
+        stream: ext://sys.stdout
+    loggers:
+      simpleExample:
+        level: DEBUG
+        handlers: [console]
+        propagate: no
+    root:
+      level: DEBUG
+      handlers: [console]
+
+For more information about logging using a dictionary, see
+:ref:`logging-config-api`.
+
+What happens if no configuration is provided
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If no logging configuration is provided, it is possible to have a situation
+where a logging event needs to be output, but no handlers can be found to
+output the event. The behaviour of the logging package in these
+circumstances is dependent on the Python version.
+
+For versions of Python prior to 3.2, the behaviour is as follows:
+
+* If *logging.raiseExceptions* is *False* (production mode), the event is
+  silently dropped.
+
+* If *logging.raiseExceptions* is *True* (development mode), a message
+  'No handlers could be found for logger X.Y.Z' is printed once.
+
+In Python 3.2 and later, the behaviour is as follows:
+
+* The event is output using a 'handler of last resort', stored in
+  ``logging.lastResort``. This internal handler is not associated with any
+  logger, and acts like a :class:`~logging.StreamHandler` which writes the
+  event description message to the current value of ``sys.stderr`` (therefore
+  respecting any redirections which may be in effect). No formatting is
+  done on the message - just the bare event description message is printed.
+  The handler's level is set to ``WARNING``, so all events at this and
+  greater severities will be output.
+
+To obtain the pre-3.2 behaviour, ``logging.lastResort`` can be set to *None*.
+
+.. _library-config:
+
+Configuring Logging for a Library
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When developing a library which uses logging, you should take care to
+document how the library uses logging - for example, the names of loggers
+used. Some consideration also needs to be given to its logging configuration.
+If the using application does not use logging, and library code makes logging
+calls, then (as described in the previous section) events of severity
+``WARNING`` and greater will be printed to ``sys.stderr``. This is regarded as
+the best default behaviour.
+
+If for some reason you *don't* want these messages printed in the absence of
+any logging configuration, you can attach a do-nothing handler to the top-level
+logger for your library. This avoids the message being printed, since a handler
+will be always be found for the library's events: it just doesn't produce any
+output. If the library user configures logging for application use, presumably
+that configuration will add some handlers, and if levels are suitably
+configured then logging calls made in library code will send output to those
+handlers, as normal.
+
+A do-nothing handler is included in the logging package:
+:class:`~logging.NullHandler` (since Python 3.1). An instance of this handler
+could be added to the top-level logger of the logging namespace used by the
+library (*if* you want to prevent your library's logged events being output to
+``sys.stderr`` in the absence of logging configuration). If all logging by a
+library *foo* is done using loggers with names matching 'foo.x', 'foo.x.y',
+etc. then the code::
+
+    import logging
+    logging.getLogger('foo').addHandler(logging.NullHandler())
+
+should have the desired effect. If an organisation produces a number of
+libraries, then the logger name specified can be 'orgname.foo' rather than
+just 'foo'.
+
+**PLEASE NOTE:** It is strongly advised that you *do not add any handlers other
+than* :class:`~logging.NullHandler` *to your library's loggers*. This is
+because the configuration of handlers is the prerogative of the application
+developer who uses your library. The application developer knows their target
+audience and what handlers are most appropriate for their application: if you
+add handlers 'under the hood', you might well interfere with their ability to
+carry out unit tests and deliver logs which suit their requirements.
+
+
+Logging Levels
+--------------
+
+The numeric values of logging levels are given in the following table. These are
+primarily of interest if you want to define your own levels, and need them to
+have specific values relative to the predefined levels. If you define a level
+with the same numeric value, it overwrites the predefined value; the predefined
+name is lost.
+
++--------------+---------------+
+| Level        | Numeric value |
++==============+===============+
+| ``CRITICAL`` | 50            |
++--------------+---------------+
+| ``ERROR``    | 40            |
++--------------+---------------+
+| ``WARNING``  | 30            |
++--------------+---------------+
+| ``INFO``     | 20            |
++--------------+---------------+
+| ``DEBUG``    | 10            |
++--------------+---------------+
+| ``NOTSET``   | 0             |
++--------------+---------------+
+
+Levels can also be associated with loggers, being set either by the developer or
+through loading a saved logging configuration. When a logging method is called
+on a logger, the logger compares its own level with the level associated with
+the method call. If the logger's level is higher than the method call's, no
+logging message is actually generated. This is the basic mechanism controlling
+the verbosity of logging output.
+
+Logging messages are encoded as instances of the :class:`~logging.LogRecord`
+class. When a logger decides to actually log an event, a
+:class:`~logging.LogRecord` instance is created from the logging message.
+
+Logging messages are subjected to a dispatch mechanism through the use of
+:dfn:`handlers`, which are instances of subclasses of the :class:`Handler`
+class. Handlers are responsible for ensuring that a logged message (in the form
+of a :class:`LogRecord`) ends up in a particular location (or set of locations)
+which is useful for the target audience for that message (such as end users,
+support desk staff, system administrators, developers). Handlers are passed
+:class:`LogRecord` instances intended for particular destinations. Each logger
+can have zero, one or more handlers associated with it (via the
+:meth:`~Logger.addHandler` method of :class:`Logger`). In addition to any
+handlers directly associated with a logger, *all handlers associated with all
+ancestors of the logger* are called to dispatch the message (unless the
+*propagate* flag for a logger is set to a false value, at which point the
+passing to ancestor handlers stops).
+
+Just as for loggers, handlers can have levels associated with them. A handler's
+level acts as a filter in the same way as a logger's level does. If a handler
+decides to actually dispatch an event, the :meth:`~Handler.emit` method is used
+to send the message to its destination. Most user-defined subclasses of
+:class:`Handler` will need to override this :meth:`~Handler.emit`.
+
+.. _custom-levels:
+
+Custom Levels
+^^^^^^^^^^^^^
+
+Defining your own levels is possible, but should not be necessary, as the
+existing levels have been chosen on the basis of practical experience.
+However, if you are convinced that you need custom levels, great care should
+be exercised when doing this, and it is possibly *a very bad idea to define
+custom levels if you are developing a library*. That's because if multiple
+library authors all define their own custom levels, there is a chance that
+the logging output from such multiple libraries used together will be
+difficult for the using developer to control and/or interpret, because a
+given numeric value might mean different things for different libraries.
+
+.. _useful-handlers:
+
+Useful Handlers
+---------------
+
+In addition to the base :class:`Handler` class, many useful subclasses are
+provided:
+
+#. :class:`StreamHandler` instances send messages to streams (file-like
+   objects).
+
+#. :class:`FileHandler` instances send messages to disk files.
+
+#. :class:`~handlers.BaseRotatingHandler` is the base class for handlers that
+   rotate log files at a certain point. It is not meant to be  instantiated
+   directly. Instead, use :class:`~handlers.RotatingFileHandler` or
+   :class:`~handlers.TimedRotatingFileHandler`.
+
+#. :class:`~handlers.RotatingFileHandler` instances send messages to disk
+   files, with support for maximum log file sizes and log file rotation.
+
+#. :class:`~handlers.TimedRotatingFileHandler` instances send messages to
+   disk files, rotating the log file at certain timed intervals.
+
+#. :class:`~handlers.SocketHandler` instances send messages to TCP/IP
+   sockets.
+
+#. :class:`~handlers.DatagramHandler` instances send messages to UDP
+   sockets.
+
+#. :class:`~handlers.SMTPHandler` instances send messages to a designated
+   email address.
+
+#. :class:`~handlers.SysLogHandler` instances send messages to a Unix
+   syslog daemon, possibly on a remote machine.
+
+#. :class:`~handlers.NTEventLogHandler` instances send messages to a
+   Windows NT/2000/XP event log.
+
+#. :class:`~handlers.MemoryHandler` instances send messages to a buffer
+   in memory, which is flushed whenever specific criteria are met.
+
+#. :class:`~handlers.HTTPHandler` instances send messages to an HTTP
+   server using either ``GET`` or ``POST`` semantics.
+
+#. :class:`~handlers.WatchedFileHandler` instances watch the file they are
+   logging to. If the file changes, it is closed and reopened using the file
+   name. This handler is only useful on Unix-like systems; Windows does not
+   support the underlying mechanism used.
+
+#. :class:`~handlers.QueueHandler` instances send messages to a queue, such as
+   those implemented in the :mod:`queue` or :mod:`multiprocessing` modules.
+
+#. :class:`NullHandler` instances do nothing with error messages. They are used
+   by library developers who want to use logging, but want to avoid the 'No
+   handlers could be found for logger XXX' message which can be displayed if
+   the library user has not configured logging. See :ref:`library-config` for
+   more information.
+
+.. versionadded:: 3.1
+   The :class:`NullHandler` class.
+
+.. versionadded:: 3.2
+   The :class:`~handlers.QueueHandler` class.
+
+The :class:`NullHandler`, :class:`StreamHandler` and :class:`FileHandler`
+classes are defined in the core logging package. The other handlers are
+defined in a sub- module, :mod:`logging.handlers`. (There is also another
+sub-module, :mod:`logging.config`, for configuration functionality.)
+
+Logged messages are formatted for presentation through instances of the
+:class:`Formatter` class. They are initialized with a format string suitable for
+use with the % operator and a dictionary.
+
+For formatting multiple messages in a batch, instances of
+:class:`BufferingFormatter` can be used. In addition to the format string (which
+is applied to each message in the batch), there is provision for header and
+trailer format strings.
+
+When filtering based on logger level and/or handler level is not enough,
+instances of :class:`Filter` can be added to both :class:`Logger` and
+:class:`Handler` instances (through their :meth:`addFilter` method). Before
+deciding to process a message further, both loggers and handlers consult all
+their filters for permission. If any filter returns a false value, the message
+is not processed further.
+
+The basic :class:`Filter` functionality allows filtering by specific logger
+name. If this feature is used, messages sent to the named logger and its
+children are allowed through the filter, and all others dropped.
+
+
+.. _logging-exceptions:
+
+Exceptions raised during logging
+--------------------------------
+
+The logging package is designed to swallow exceptions which occur while logging
+in production. This is so that errors which occur while handling logging events
+- such as logging misconfiguration, network or other similar errors - do not
+cause the application using logging to terminate prematurely.
+
+:class:`SystemExit` and :class:`KeyboardInterrupt` exceptions are never
+swallowed. Other exceptions which occur during the :meth:`emit` method of a
+:class:`Handler` subclass are passed to its :meth:`handleError` method.
+
+The default implementation of :meth:`handleError` in :class:`Handler` checks
+to see if a module-level variable, :data:`raiseExceptions`, is set. If set, a
+traceback is printed to :data:`sys.stderr`. If not set, the exception is swallowed.
+
+**Note:** The default value of :data:`raiseExceptions` is ``True``. This is because
+during development, you typically want to be notified of any exceptions that
+occur. It's advised that you set :data:`raiseExceptions` to ``False`` for production
+usage.
+
+.. currentmodule:: logging
+
+.. _arbitrary-object-messages:
+
+Using arbitrary objects as messages
+-----------------------------------
+
+In the preceding sections and examples, it has been assumed that the message
+passed when logging the event is a string. However, this is not the only
+possibility. You can pass an arbitrary object as a message, and its
+:meth:`__str__` method will be called when the logging system needs to convert
+it to a string representation. In fact, if you want to, you can avoid
+computing a string representation altogether - for example, the
+:class:`SocketHandler` emits an event by pickling it and sending it over the
+wire.
+
+
+Optimization
+------------
+
+Formatting of message arguments is deferred until it cannot be avoided.
+However, computing the arguments passed to the logging method can also be
+expensive, and you may want to avoid doing it if the logger will just throw
+away your event. To decide what to do, you can call the :meth:`isEnabledFor`
+method which takes a level argument and returns true if the event would be
+created by the Logger for that level of call. You can write code like this::
+
+    if logger.isEnabledFor(logging.DEBUG):
+        logger.debug('Message with %s, %s', expensive_func1(),
+                                            expensive_func2())
+
+so that if the logger's threshold is set above ``DEBUG``, the calls to
+:func:`expensive_func1` and :func:`expensive_func2` are never made.
+
+There are other optimizations which can be made for specific applications which
+need more precise control over what logging information is collected. Here's a
+list of things you can do to avoid processing during logging which you don't
+need:
+
++-----------------------------------------------+----------------------------------------+
+| What you don't want to collect                | How to avoid collecting it             |
++===============================================+========================================+
+| Information about where calls were made from. | Set ``logging._srcfile`` to ``None``.  |
++-----------------------------------------------+----------------------------------------+
+| Threading information.                        | Set ``logging.logThreads`` to ``0``.   |
++-----------------------------------------------+----------------------------------------+
+| Process information.                          | Set ``logging.logProcesses`` to ``0``. |
++-----------------------------------------------+----------------------------------------+
+
+Also note that the core logging module only includes the basic handlers. If
+you don't import :mod:`logging.handlers` and :mod:`logging.config`, they won't
+take up any memory.

+*********************************
+Porting Python 2 Code to Python 3
+*********************************
+
+:author: Brett Cannon
+
+.. topic:: Abstract
+
+   With Python 3 being the future of Python while Python 2 is still in active
+   use, it is good to have your project available for both major releases of
+   Python. This guide is meant to help you choose which strategy works best
+   for your project to support both Python 2 & 3 along with how to execute
+   that strategy.
+
+   If you are looking to port an extension module instead of pure Python code,
+   please see :ref:`cporting-howto`.
+
+
+Choosing a Strategy
+===================
+
+When a project makes the decision that it's time to support both Python 2 & 3,
+a decision needs to be made as to how to go about accomplishing that goal.
+The chosen strategy will depend on how large the project's existing
+codebase is and how much divergence you want from your Python 2 codebase from
+your Python 3 one (e.g., starting a new version with Python 3).
+
+If your project is brand-new or does not have a large codebase, then you may
+want to consider writing/porting :ref:`all of your code for Python 3
+and use 3to2 <use_3to2>` to port your code for Python 2.
+
+If you would prefer to maintain a codebase which is semantically **and**
+syntactically compatible with Python 2 & 3 simultaneously, you can write
+:ref:`use_same_source`. While this tends to lead to somewhat non-idiomatic
+code, it does mean you keep a rapid development process for you, the developer.
+
+Finally, you do have the option of :ref:`using 2to3 <use_2to3>` to translate
+Python 2 code into Python 3 code (with some manual help). This can take the
+form of branching your code and using 2to3 to start a Python 3 branch. You can
+also have users perform the translation as installation time automatically so
+that you only have to maintain a Python 2 codebase.
+
+Regardless of which approach you choose, porting is not as hard or
+time-consuming as you might initially think. You can also tackle the problem
+piece-meal as a good portion of porting is simply updating your code to follow
+current best practices in a Python 2/3 compatible way.
+
+
+Universal Bits of Advice
+------------------------
+
+Regardless of what strategy you pick, there are a few things you should
+consider.
+
+One is make sure you have a robust test suite. You need to make sure everything
+continues to work, just like when you support a new minor version of Python.
+This means making sure your test suite is thorough and is ported properly
+between Python 2 & 3. You will also most likely want to use something like tox_
+to automate testing between both a Python 2 and Python 3 VM.
+
+Two, once your project has Python 3 support, make sure to add the proper
+classifier on the Cheeseshop_ (PyPI_). To have your project listed as Python 3
+compatible it must have the
+`Python 3 classifier <http://pypi.python.org/pypi?:action=browse&c=533>`_
+(from
+http://techspot.zzzeek.org/2011/01/24/zzzeek-s-guide-to-python-3-porting/)::
+
+   setup(
+     name='Your Library',
+     version='1.0',
+     classifiers=[
+         # make sure to use :: Python *and* :: Python :: 3 so
+         # that pypi can list the package on the python 3 page
+         'Programming Language :: Python',
+         'Programming Language :: Python :: 3'
+     ],
+     packages=['yourlibrary'],
+     # make sure to add custom_fixers to the MANIFEST.in
+     include_package_data=True,
+     # ...
+   )
+
+
+Doing so will cause your project to show up in the
+`Python 3 packages list
+<http://pypi.python.org/pypi?:action=browse&c=533&show=all>`_. You will know
+you set the classifier properly as visiting your project page on the Cheeseshop
+will show a Python 3 logo in the upper-left corner of the page.
+
+Three, the six_ project provides a library which helps iron out differences
+between Python 2 & 3. If you find there is a sticky point that is a continual
+point of contention in your translation or maintenance of code, consider using
+a source-compatible solution relying on six. If you have to create your own
+Python 2/3 compatible solution, you can use ``sys.version_info[0] >= 3`` as a
+guard.
+
+Four, read all the approaches. Just because some bit of advice applies to one
+approach more than another doesn't mean that some advice doesn't apply to other
+strategies.
+
+Five, drop support for older Python versions if possible. `Python 2.5`_
+introduced a lot of useful syntax and libraries which have become idiomatic
+in Python 3. `Python 2.6`_ introduced future statements which makes
+compatibility much easier if you are going from Python 2 to 3.

+and work from there.

+
+Python 3 and 3to2
+=================
+
+If you are starting a new project or your codebase is small enough, you may
+want to consider writing your code for Python 3 and backporting to Python 2
+using 3to2_. Thanks to Python 3 being more strict about things than Python 2
+(e.g., bytes vs. strings), the source translation can be easier and more
+straightforward than from Python 2 to 3. Plus it gives you more direct
+experience developing in Python 3 which, since it is the future of Python, is a
+good thing long-term.
+
+A drawback of this approach is that 3to2 is a third-party project. This means
+that the Python core developers (and thus this guide) can make no promises
+about how well 3to2 works at any time. There is nothing to suggest, though,
+that 3to2 is not a high-quality project.
+
+
+.. _3to2: https://bitbucket.org/amentajo/lib3to2/overview
+
+
+.. _use_2to3:
+
+Python 2 and 2to3
+=================
+
+Included with Python since 2.6, the 2to3_ tool (and :mod:`lib2to3` module)
+helps with porting Python 2 to Python 3 by performing various source
+translations. This is a perfect solution for projects which wish to branch
+their Python 3 code from their Python 2 codebase and maintain them as
+independent codebases. You can even begin preparing to use this approach
+today by writing future-compatible Python code which works cleanly in
+Python 2 in conjunction with 2to3; all steps outlined below will work
+with Python 2 code up to the point when the actual use of 2to3 occurs.
+
+Use of 2to3 as an on-demand translation step at install time is also possible,
+preventing the need to maintain a separate Python 3 codebase, but this approach
+does come with some drawbacks. While users will only have to pay the
+translation cost once at installation, you as a developer will need to pay the
+cost regularly during development. If your codebase is sufficiently large
+enough then the translation step ends up acting like a compilation step,
+robbing you of the rapid development process you are used to with Python.
+Obviously the time required to translate a project will vary, so do an
+experimental translation just to see how long it takes to evaluate whether you
+prefer this approach compared to using :ref:`use_same_source` or simply keeping
+a separate Python 3 codebase.
+
+Below are the typical steps taken by a project which uses a 2to3-based approach
+to supporting Python 2 & 3.
+
+
+Support Python 2.7
+------------------
+
+As a first step, make sure that your project is compatible with `Python 2.7`_.
+This is just good to do as Python 2.7 is the last release of Python 2 and thus
+will be used for a rather long time. It also allows for use of the ``-3`` flag
+to Python to help discover places in your code which 2to3 cannot handle but are
+known to cause issues.
+
+Try to Support `Python 2.6`_ and Newer Only
+-------------------------------------------
+
+While not possible for all projects, if you can support `Python 2.6`_ and newer
+**only**, your life will be much easier. Various future statements, stdlib
+additions, etc. exist only in Python 2.6 and later which greatly assist in
+porting to Python 3. But if you project must keep support for `Python 2.5`_ (or
+even `Python 2.4`_) then it is still possible to port to Python 3.
+
+Below are the benefits you gain if you only have to support Python 2.6 and
+newer. Some of these options are personal choice while others are
+**strongly** recommended (the ones that are more for personal choice are
+labeled as such).  If you continue to support older versions of Python then you
+at least need to watch out for situations that these solutions fix.
+
+
+``from __future__ import print_function``
+'''''''''''''''''''''''''''''''''''''''''
+
+This is a personal choice. 2to3 handles the translation from the print
+statement to the print function rather well so this is an optional step. This
+future statement does help, though, with getting used to typing
+``print('Hello, World')`` instead of ``print 'Hello, World'``.
+
+
+``from __future__ import unicode_literals``
+'''''''''''''''''''''''''''''''''''''''''''
+
+Another personal choice. You can always mark what you want to be a (unicode)
+string with a ``u`` prefix to get the same effect. But regardless of whether
+you use this future statement or not, you **must** make sure you know exactly
+which Python 2 strings you want to be bytes, and which are to be strings. This
+means you should, **at minimum** mark all strings that are meant to be text
+strings with a ``u`` prefix if you do not use this future statement.
+
+
+Bytes literals
+''''''''''''''
+
+This is a **very** important one. The ability to prefix Python 2 strings that
+are meant to contain bytes with a ``b`` prefix help to very clearly delineate
+what is and is not a Python 3 string. When you run 2to3 on code, all Python 2
+strings become Python 3 strings **unless** they are prefixed with ``b``.
+
+There are some differences between byte literals in Python 2 and those in
+Python 3 thanks to the bytes type just being an alias to ``str`` in Python 2.
+Probably the biggest "gotcha" is that indexing results in different values. In
+Python 2, the value of ``b'py'[1]`` is ``'y'``, while in Python 3 it's ``121``.
+You can avoid this disparity by always slicing at the size of a single element:
+``b'py'[1:2]`` is ``'y'`` in Python 2 and ``b'y'`` in Python 3 (i.e., close
+enough).
+
+You cannot concatenate bytes and strings in Python 3. But since in Python
+2 has bytes aliased to ``str``, it will succeed: ``b'a' + u'b'`` works in
+Python 2, but ``b'a' + 'b'`` in Python 3 is a :exc:`TypeError`. A similar issue
+also comes about when doing comparisons between bytes and strings.
+
+
+Supporting `Python 2.5`_ and Newer Only
+---------------------------------------
+
+If you are supporting `Python 2.5`_ and newer there are still some features of
+Python that you can utilize.
+
+
+``from __future__ import absolute_imports``
+'''''''''''''''''''''''''''''''''''''''''''
+
+Implicit relative imports (e.g., importing ``spam.bacon`` from within
+``spam.eggs`` with the statement ``import bacon``) does not work in Python 3.
+This future statement moves away from that and allows the use of explicit
+relative imports (e.g., ``from . import bacon``).
+
+In `Python 2.5`_ you must use
+the __future__ statement to get to use explicit relative imports and prevent
+implicit ones. In `Python 2.6`_ explicit relative imports are available without
+the statement, but you still want the __future__ statement to prevent implicit
+relative imports. In `Python 2.7`_ the __future__ statement is not needed. In
+other words, unless you are only supporting Python 2.7 or a version earlier
+than Python 2.5, use the __future__ statement.
+
+
+
+Handle Common "Gotchas"
+-----------------------
+
+There are a few things that just consistently come up as sticking points for
+people which 2to3 cannot handle automatically or can easily be done in Python 2
+to help modernize your code.
+
+
+``from __future__ import division``
+'''''''''''''''''''''''''''''''''''
+
+While the exact same outcome can be had by using the ``-Qnew`` argument to
+Python, using this future statement lifts the requirement that your users use
+the flag to get the expected behavior of division in Python 3
+(e.g., ``1/2 == 0.5; 1//2 == 0``).
+
+
+
+Specify when opening a file as binary
+'''''''''''''''''''''''''''''''''''''
+
+Unless you have been working on Windows, there is a chance you have not always
+bothered to add the ``b`` mode when opening a binary file (e.g., ``rb`` for
+binary reading).  Under Python 3, binary files and text files are clearly
+distinct and mutually incompatible; see the :mod:`io` module for details.
+Therefore, you **must** make a decision of whether a file will be used for
+binary access (allowing to read and/or write bytes data) or text access
+(allowing to read and/or write unicode data).
+
+Text files
+''''''''''
+
+Text files created using ``open()`` under Python 2 return byte strings,
+while under Python 3 they return unicode strings.  Depending on your porting
+strategy, this can be an issue.
+
+If you want text files to return unicode strings in Python 2, you have two
+possibilities:
+
+* Under Python 2.6 and higher, use :func:`io.open`.  Since :func:`io.open`
+  is essentially the same function in both Python 2 and Python 3, it will
+  help iron out any issues that might arise.
+
+* If pre-2.6 compatibility is needed, then you should use :func:`codecs.open`
+  instead.  This will make sure that you get back unicode strings in Python 2.
+
+Subclass ``object``
+'''''''''''''''''''
+
+New-style classes have been around since `Python 2.2`_. You need to make sure
+you are subclassing from ``object`` to avoid odd edge cases involving method
+resolution order, etc. This continues to be totally valid in Python 3 (although
+unneeded as all classes implicitly inherit from ``object``).
+
+
+Deal With the Bytes/String Dichotomy
+''''''''''''''''''''''''''''''''''''
+
+One of the biggest issues people have when porting code to Python 3 is handling
+the bytes/string dichotomy. Because Python 2 allowed the ``str`` type to hold
+textual data, people have over the years been rather loose in their delineation
+of what ``str`` instances held text compared to bytes. In Python 3 you cannot
+be so care-free anymore and need to properly handle the difference. The key
+handling this issue to to make sure that **every** string literal in your
+Python 2 code is either syntactically of functionally marked as either bytes or
+text data. After this is done you then need to make sure your APIs are designed
+to either handle a specific type or made to be properly polymorphic.
+
+
+Mark Up Python 2 String Literals
+********************************
+
+First thing you must do is designate every single string literal in Python 2
+as either textual or bytes data. If you are only supporting Python 2.6 or
+newer, this can be accomplished by marking bytes literals with a ``b`` prefix
+and then designating textual data with a ``u`` prefix or using the
+``unicode_literals`` future statement.
+
+If your project supports versions of Python pre-dating 2.6, then you should use
+the six_ project and its ``b()`` function to denote bytes literals. For text
+literals you can either use six's ``u()`` function or use a ``u`` prefix.
+
+
+Decide what APIs Will Accept
+****************************
+
+In Python 2 it was very easy to accidentally create an API that accepted both
+bytes and textual data. But in Python 3, thanks to the more strict handling of
+disparate types, this loose usage of bytes and text together tends to fail.
+
+Take the dict ``{b'a': 'bytes', u'a': 'text'}`` in Python 2.6. It creates the
+dict ``{u'a': 'text'}`` since ``b'a' == u'a'``. But in Python 3 the equivalent
+dict creates ``{b'a': 'bytes', 'a': 'text'}``, i.e., no lost data. Similar
+issues can crop up when transitioning Python 2 code to Python 3.
+
+This means you need to choose what an API is going to accept and create and
+consistently stick to that API in both Python 2 and 3.
+
+
+Bytes / Unicode Comparison
+**************************
+
+In Python 3, mixing bytes and unicode is forbidden in most situations; it
+will raise a :class:`TypeError` where Python 2 would have attempted an implicit
+coercion between types.  However, there is one case where it doesn't and
+it can be very misleading::
+
+   >>> b"" == ""
+   False
+
+This is because an equality comparison is required by the language to always
+succeed (and return ``False`` for incompatible types).  However, this also
+means that code incorrectly ported to Python 3 can display buggy behaviour
+if such comparisons are silently executed.  To detect such situations,
+Python 3 has a ``-b`` flag that will display a warning::
+
+   $ python3 -b
+   >>> b"" == ""
+   __main__:1: BytesWarning: Comparison between bytes and string
+   False
+
+To turn the warning into an exception, use the ``-bb`` flag instead::
+
+   $ python3 -bb
+   >>> b"" == ""
+   Traceback (most recent call last):
+     File "<stdin>", line 1, in <module>
+   BytesWarning: Comparison between bytes and string
+
+
+Indexing bytes objects
+''''''''''''''''''''''
+
+Another potentially surprising change is the indexing behaviour of bytes
+objects in Python 3::
+
+   >>> b"xyz"[0]
+   120
+
+Indeed, Python 3 bytes objects (as well as :class:`bytearray` objects)
+are sequences of integers.  But code converted from Python 2 will often
+assume that indexing a bytestring produces another bytestring, not an
+integer.  To reconcile both behaviours, use slicing::
+
+   >>> b"xyz"[0:1]
+   b'x'
+   >>> n = 1
+   >>> b"xyz"[n:n+1]
+   b'y'
+
+The only remaining gotcha is that an out-of-bounds slice returns an empty
+bytes object instead of raising ``IndexError``:
+
+   >>> b"xyz"[3]
+   Traceback (most recent call last):
+     File "<stdin>", line 1, in <module>
+   IndexError: index out of range
+   >>> b"xyz"[3:4]
+   b''
+
+
+``__str__()``/``__unicode__()``
+'''''''''''''''''''''''''''''''
+
+In Python 2, objects can specify both a string and unicode representation of
+themselves. In Python 3, though, there is only a string representation. This
+becomes an issue as people can inadvertently do things in their ``__str__()``
+methods which have unpredictable results (e.g., infinite recursion if you
+happen to use the ``unicode(self).encode('utf8')`` idiom as the body of your
+``__str__()`` method).
+
+There are two ways to solve this issue. One is to use a custom 2to3 fixer. The
+blog post at http://lucumr.pocoo.org/2011/1/22/forwards-compatible-python/
+specifies how to do this. That will allow 2to3 to change all instances of ``def
+__unicode(self): ...`` to ``def __str__(self): ...``. This does require you
+define your ``__str__()`` method in Python 2 before your ``__unicode__()``
+method.
+
+The other option is to use a mixin class. This allows you to only define a
+``__unicode__()`` method for your class and let the mixin derive
+``__str__()`` for you (code from
+http://lucumr.pocoo.org/2011/1/22/forwards-compatible-python/)::
+
+   import sys
+
+   class UnicodeMixin(object):
+
+     """Mixin class to handle defining the proper __str__/__unicode__
+     methods in Python 2 or 3."""
+
+     if sys.version_info[0] >= 3: # Python 3
+         def __str__(self):
+             return self.__unicode__()
+     else:  # Python 2
+         def __str__(self):
+             return self.__unicode__().encode('utf8')
+
+
+   class Spam(UnicodeMixin):
+
+     def __unicode__(self):
+         return u'spam-spam-bacon-spam'  # 2to3 will remove the 'u' prefix
+
+
+Don't Index on Exceptions
+'''''''''''''''''''''''''
+
+In Python 2, the following worked::
+
+   >>> exc = Exception(1, 2, 3)
+   >>> exc.args[1]
+   2
+   >>> exc[1]  # Python 2 only!
+   2
+
+But in Python 3, indexing directly on an exception is an error. You need to
+make sure to only index on the :attr:`BaseException.args` attribute which is a
+sequence containing all arguments passed to the :meth:`__init__` method.
+
+Even better is to use the documented attributes the exception provides.
+
+Don't use ``__getslice__`` & Friends
+''''''''''''''''''''''''''''''''''''
+
+Been deprecated for a while, but Python 3 finally drops support for
+``__getslice__()``, etc. Move completely over to :meth:`__getitem__` and
+friends.
+
+
+Updating doctests
+'''''''''''''''''
+
+2to3_ will attempt to generate fixes for doctests that it comes across. It's
+not perfect, though. If you wrote a monolithic set of doctests (e.g., a single
+docstring containing all of your doctests), you should at least consider
+breaking the doctests up into smaller pieces to make it more manageable to fix.
+Otherwise it might very well be worth your time and effort to port your tests
+to :mod:`unittest`.
+
+
+Eliminate ``-3`` Warnings
+-------------------------
+
+When you run your application's test suite, run it using the ``-3`` flag passed
+to Python. This will cause various warnings to be raised during execution about
+things that 2to3 cannot handle automatically (e.g., modules that have been
+removed). Try to eliminate those warnings to make your code even more portable
+to Python 3.
+
+
+Run 2to3
+--------
+
+Once you have made your Python 2 code future-compatible with Python 3, it's
+time to use 2to3_ to actually port your code.
+
+
+Manually
+''''''''
+
+To manually convert source code using 2to3_, you use the ``2to3`` script that
+is installed with Python 2.6 and later.::
+
+   2to3 <directory or file to convert>
+
+This will cause 2to3 to write out a diff with all of the fixers applied for the
+converted source code. If you would like 2to3 to go ahead and apply the changes
+you can pass it the ``-w`` flag::
+
+   2to3 -w <stuff to convert>
+
+There are other flags available to control exactly which fixers are applied,
+etc.
+
+
+During Installation
+'''''''''''''''''''
+
+When a user installs your project for Python 3, you can have either
+:mod:`distutils` or Distribute_ run 2to3_ on your behalf.
+For distutils, use the following idiom::
+
+   try:  # Python 3
+     from distutils.command.build_py import build_py_2to3 as build_py
+   except ImportError:  # Python 2
+     from distutils.command.build_py import build_py
+
+   setup(cmdclass = {'build_py': build_py},
+     # ...
+   )
+
+For Distribute::
+
+   setup(use_2to3=True,
+     # ...
+   )
+
+This will allow you to not have to distribute a separate Python 3 version of
+your project. It does require, though, that when you perform development that
+you at least build your project and use the built Python 3 source for testing.
+
+
+Verify & Test
+-------------
+
+At this point you should (hopefully) have your project converted in such a way
+that it works in Python 3. Verify it by running your unit tests and making sure
+nothing has gone awry. If you miss something then figure out how to fix it in
+Python 3, backport to your Python 2 code, and run your code through 2to3 again
+to verify the fix transforms properly.

+
+Python 2/3 Compatible Source
+============================
+
+While it may seem counter-intuitive, you can write Python code which is
+source-compatible between Python 2 & 3. It does lead to code that is not
+entirely idiomatic Python (e.g., having to extract the currently raised
+exception from ``sys.exc_info()[1]``), but it can be run under Python 2
+**and** Python 3 without using 2to3_ as a translation step (although the tool
+should be used to help find potential portability problems). This allows you to
+continue to have a rapid development process regardless of whether you are
+developing under Python 2 or Python 3. Whether this approach or using
+:ref:`use_2to3` works best for you will be a per-project decision.
+
+To get a complete idea of what issues you will need to deal with, see the
+`What's New in Python 3.0`_. Others have reorganized the data in other formats
+such as http://docs.pythonsprints.com/python3_porting/py-porting.html .
+
+The following are some steps to take to try to support both Python 2 & 3 from
+the same source code.
+
+
+.. _What's New in Python 3.0: http://docs.python.org/release/3.0/whatsnew/3.0.html
+
+
+Follow The Steps for Using 2to3_
+--------------------------------
+
+All of the steps outlined in how to
+:ref:`port Python 2 code with 2to3 <use_2to3>` apply
+to creating a Python 2/3 codebase. This includes trying only support Python 2.6
+or newer (the :mod:`__future__` statements work in Python 3 without issue),
+eliminating warnings that are triggered by ``-3``, etc.
+
+You should even consider running 2to3_ over your code (without committing the
+changes). This will let you know where potential pain points are within your
+code so that you can fix them properly before they become an issue.
+
+
+Use six_
+--------
+
+The six_ project contains many things to help you write portable Python code.
+You should make sure to read its documentation from beginning to end and use
+any and all features it provides. That way you will minimize any mistakes you
+might make in writing cross-version code.
+
+
+Capturing the Currently Raised Exception
+----------------------------------------
+
+One change between Python 2 and 3 that will require changing how you code (if
+you support `Python 2.5`_ and earlier) is
+accessing the currently raised exception.  In Python 2.5 and earlier the syntax
+to access the current exception is::
+
+   try:
+     raise Exception()
+   except Exception, exc:
+     # Current exception is 'exc'
+     pass
+
+This syntax changed in Python 3 (and backported to `Python 2.6`_ and later)
+to::
+
+   try:
+     raise Exception()
+   except Exception as exc:
+     # Current exception is 'exc'
+     # In Python 3, 'exc' is restricted to the block; Python 2.6 will "leak"
+     pass
+
+Because of this syntax change you must change to capturing the current
+exception to::
+
+   try:
+     raise Exception()
+   except Exception:
+     import sys
+     exc = sys.exc_info()[1]
+     # Current exception is 'exc'
+     pass
+
+You can get more information about the raised exception from
+:func:`sys.exc_info` than simply the current exception instance, but you most
+likely don't need it.
+
+.. note::
+   In Python 3, the traceback is attached to the exception instance
+   through the ``__traceback__`` attribute. If the instance is saved in
+   a local variable that persists outside of the ``except`` block, the
+   traceback will create a reference cycle with the current frame and its
+   dictionary of local variables.  This will delay reclaiming dead
+   resources until the next cyclic :term:`garbage collection` pass.
+
+   In Python 2, this problem only occurs if you save the traceback itself
+   (e.g. the third element of the tuple returned by :func:`sys.exc_info`)
+   in a variable.

+:mod:`argparse` --- Parser for command line options, arguments and sub-commands
+===============================================================================
+
+.. module:: argparse
+   :synopsis: Command-line option and argument parsing library.
+.. moduleauthor:: Steven Bethard <steven.bethard@gmail.com>
+.. sectionauthor:: Steven Bethard <steven.bethard@gmail.com>
+
+**Source code:** :source:`Lib/argparse.py`
+
+.. versionadded:: 3.2
+
+--------------
+
+The :mod:`argparse` module makes it easy to write user friendly command line
+interfaces. The program defines what arguments it requires, and :mod:`argparse`
+will figure out how to parse those out of :data:`sys.argv`.  The :mod:`argparse`
+module also automatically generates help and usage messages and issues errors
+when users give the program invalid arguments.
+
+
+Example
+-------
+
+The following code is a Python program that takes a list of integers and
+produces either the sum or the max::
+
+   import argparse
+
+   parser = argparse.ArgumentParser(description='Process some integers.')
+   parser.add_argument('integers', metavar='N', type=int, nargs='+',
+                      help='an integer for the accumulator')
+   parser.add_argument('--sum', dest='accumulate', action='store_const',
+                      const=sum, default=max,
+                      help='sum the integers (default: find the max)')
+
+   args = parser.parse_args()
+   print(args.accumulate(args.integers))
+
+Assuming the Python code above is saved into a file called ``prog.py``, it can
+be run at the command line and provides useful help messages::
+
+   $ prog.py -h
+   usage: prog.py [-h] [--sum] N [N ...]
+
+   Process some integers.
+
+   positional arguments:
+    N           an integer for the accumulator
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --sum       sum the integers (default: find the max)
+
+When run with the appropriate arguments, it prints either the sum or the max of
+the command-line integers::
+
+   $ prog.py 1 2 3 4
+   4
+
+   $ prog.py 1 2 3 4 --sum
+   10
+
+If invalid arguments are passed in, it will issue an error::
+
+   $ prog.py a b c
+   usage: prog.py [-h] [--sum] N [N ...]
+   prog.py: error: argument N: invalid int value: 'a'
+
+The following sections walk you through this example.
+
+
+Creating a parser
+^^^^^^^^^^^^^^^^^
+
+The first step in using the :mod:`argparse` is creating an
+:class:`ArgumentParser` object::
+
+   >>> parser = argparse.ArgumentParser(description='Process some integers.')
+
+The :class:`ArgumentParser` object will hold all the information necessary to
+parse the command line into python data types.
+
+
+Adding arguments
+^^^^^^^^^^^^^^^^
+
+Filling an :class:`ArgumentParser` with information about program arguments is
+done by making calls to the :meth:`~ArgumentParser.add_argument` method.
+Generally, these calls tell the :class:`ArgumentParser` how to take the strings
+on the command line and turn them into objects.  This information is stored and
+used when :meth:`~ArgumentParser.parse_args` is called. For example::
+
+   >>> parser.add_argument('integers', metavar='N', type=int, nargs='+',
+   ...                     help='an integer for the accumulator')
+   >>> parser.add_argument('--sum', dest='accumulate', action='store_const',
+   ...                     const=sum, default=max,
+   ...                     help='sum the integers (default: find the max)')
+
+Later, calling :meth:`parse_args` will return an object with
+two attributes, ``integers`` and ``accumulate``.  The ``integers`` attribute
+will be a list of one or more ints, and the ``accumulate`` attribute will be
+either the :func:`sum` function, if ``--sum`` was specified at the command line,
+or the :func:`max` function if it was not.
+
+
+Parsing arguments
+^^^^^^^^^^^^^^^^^
+
+:class:`ArgumentParser` parses args through the
+:meth:`~ArgumentParser.parse_args` method.  This will inspect the command-line,
+convert each arg to the appropriate type and then invoke the appropriate action.
+In most cases, this means a simple namespace object will be built up from
+attributes parsed out of the command-line::
+
+   >>> parser.parse_args(['--sum', '7', '-1', '42'])
+   Namespace(accumulate=<built-in function sum>, integers=[7, -1, 42])
+
+In a script, :meth:`~ArgumentParser.parse_args` will typically be called with no
+arguments, and the :class:`ArgumentParser` will automatically determine the
+command-line args from :data:`sys.argv`.
+
+
+ArgumentParser objects
+----------------------
+
+.. class:: ArgumentParser([description], [epilog], [prog], [usage], [add_help], \
+                          [argument_default], [parents], [prefix_chars], \
+                          [conflict_handler], [formatter_class])
+
+   Create a new :class:`ArgumentParser` object.  Each parameter has its own more
+   detailed description below, but in short they are:
+
+   * description_ - Text to display before the argument help.
+
+   * epilog_ - Text to display after the argument help.
+
+   * add_help_ - Add a -h/--help option to the parser. (default: ``True``)
+
+   * argument_default_ - Set the global default value for arguments.
+     (default: ``None``)
+
+   * parents_ - A list of :class:`ArgumentParser` objects whose arguments should
+     also be included.
+
+   * prefix_chars_ - The set of characters that prefix optional arguments.
+     (default: '-')
+
+   * fromfile_prefix_chars_ - The set of characters that prefix files from
+     which additional arguments should be read. (default: ``None``)
+
+   * formatter_class_ - A class for customizing the help output.
+
+   * conflict_handler_ - Usually unnecessary, defines strategy for resolving
+     conflicting optionals.
+
+   * prog_ - The name of the program (default:
+     :data:`sys.argv[0]`)
+
+   * usage_ - The string describing the program usage (default: generated)
+
+The following sections describe how each of these are used.
+
+
+description
+^^^^^^^^^^^
+
+Most calls to the :class:`ArgumentParser` constructor will use the
+``description=`` keyword argument.  This argument gives a brief description of
+what the program does and how it works.  In help messages, the description is
+displayed between the command-line usage string and the help messages for the
+various arguments::
+
+   >>> parser = argparse.ArgumentParser(description='A foo that bars')
+   >>> parser.print_help()
+   usage: argparse.py [-h]
+
+   A foo that bars
+
+   optional arguments:
+    -h, --help  show this help message and exit
+
+By default, the description will be line-wrapped so that it fits within the
+given space.  To change this behavior, see the formatter_class_ argument.
+
+
+epilog
+^^^^^^
+
+Some programs like to display additional description of the program after the
+description of the arguments.  Such text can be specified using the ``epilog=``
+argument to :class:`ArgumentParser`::
+
+   >>> parser = argparse.ArgumentParser(
+   ...     description='A foo that bars',
+   ...     epilog="And that's how you'd foo a bar")
+   >>> parser.print_help()
+   usage: argparse.py [-h]
+
+   A foo that bars
+
+   optional arguments:
+    -h, --help  show this help message and exit
+
+   And that's how you'd foo a bar
+
+As with the description_ argument, the ``epilog=`` text is by default
+line-wrapped, but this behavior can be adjusted with the formatter_class_
+argument to :class:`ArgumentParser`.
+
+
+add_help
+^^^^^^^^
+
+By default, ArgumentParser objects add an option which simply displays
+the parser's help message. For example, consider a file named
+``myprogram.py`` containing the following code::
+
+   import argparse
+   parser = argparse.ArgumentParser()
+   parser.add_argument('--foo', help='foo help')
+   args = parser.parse_args()
+
+If ``-h`` or ``--help`` is supplied is at the command-line, the ArgumentParser
+help will be printed::
+
+   $ python myprogram.py --help
+   usage: myprogram.py [-h] [--foo FOO]
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --foo FOO   foo help
+
+Occasionally, it may be useful to disable the addition of this help option.
+This can be achieved by passing ``False`` as the ``add_help=`` argument to
+:class:`ArgumentParser`::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG', add_help=False)
+   >>> parser.add_argument('--foo', help='foo help')
+   >>> parser.print_help()
+   usage: PROG [--foo FOO]
+
+   optional arguments:
+    --foo FOO  foo help
+
+The help option is typically ``-h/--help``. The exception to this is
+if the ``prefix_chars=`` is specified and does not include ``'-'``, in
+which case ``-h`` and ``--help`` are not valid options.  In
+this case, the first character in ``prefix_chars`` is used to prefix
+the help options::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG', prefix_chars='+/')
+   >>> parser.print_help()
+   usage: PROG [+h]
+
+   optional arguments:
+     +h, ++help  show this help message and exit
+
+
+prefix_chars
+^^^^^^^^^^^^
+
+Most command-line options will use ``'-'`` as the prefix, e.g. ``-f/--foo``.
+Parsers that need to support different or additional prefix
+characters, e.g. for options
+like ``+f`` or ``/foo``, may specify them using the ``prefix_chars=`` argument
+to the ArgumentParser constructor::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG', prefix_chars='-+')
+   >>> parser.add_argument('+f')
+   >>> parser.add_argument('++bar')
+   >>> parser.parse_args('+f X ++bar Y'.split())
+   Namespace(bar='Y', f='X')
+
+The ``prefix_chars=`` argument defaults to ``'-'``. Supplying a set of
+characters that does not include ``'-'`` will cause ``-f/--foo`` options to be
+disallowed.
+
+
+fromfile_prefix_chars
+^^^^^^^^^^^^^^^^^^^^^
+
+Sometimes, for example when dealing with a particularly long argument lists, it
+may make sense to keep the list of arguments in a file rather than typing it out
+at the command line.  If the ``fromfile_prefix_chars=`` argument is given to the
+:class:`ArgumentParser` constructor, then arguments that start with any of the
+specified characters will be treated as files, and will be replaced by the
+arguments they contain.  For example::
+
+   >>> with open('args.txt', 'w') as fp:
+   ...    fp.write('-f\nbar')
+   >>> parser = argparse.ArgumentParser(fromfile_prefix_chars='@')
+   >>> parser.add_argument('-f')
+   >>> parser.parse_args(['-f', 'foo', '@args.txt'])
+   Namespace(f='bar')
+
+Arguments read from a file must by default be one per line (but see also
+:meth:`convert_arg_line_to_args`) and are treated as if they were in the same
+place as the original file referencing argument on the command line.  So in the
+example above, the expression ``['-f', 'foo', '@args.txt']`` is considered
+equivalent to the expression ``['-f', 'foo', '-f', 'bar']``.
+
+The ``fromfile_prefix_chars=`` argument defaults to ``None``, meaning that
+arguments will never be treated as file references.
+
+
+argument_default
+^^^^^^^^^^^^^^^^
+
+Generally, argument defaults are specified either by passing a default to
+:meth:`add_argument` or by calling the :meth:`set_defaults` methods with a
+specific set of name-value pairs.  Sometimes however, it may be useful to
+specify a single parser-wide default for arguments.  This can be accomplished by
+passing the ``argument_default=`` keyword argument to :class:`ArgumentParser`.
+For example, to globally suppress attribute creation on :meth:`parse_args`
+calls, we supply ``argument_default=SUPPRESS``::
+
+   >>> parser = argparse.ArgumentParser(argument_default=argparse.SUPPRESS)
+   >>> parser.add_argument('--foo')
+   >>> parser.add_argument('bar', nargs='?')
+   >>> parser.parse_args(['--foo', '1', 'BAR'])
+   Namespace(bar='BAR', foo='1')
+   >>> parser.parse_args([])
+   Namespace()
+
+
+parents
+^^^^^^^
+
+Sometimes, several parsers share a common set of arguments. Rather than
+repeating the definitions of these arguments, a single parser with all the
+shared arguments and passed to ``parents=`` argument to :class:`ArgumentParser`
+can be used.  The ``parents=`` argument takes a list of :class:`ArgumentParser`
+objects, collects all the positional and optional actions from them, and adds
+these actions to the :class:`ArgumentParser` object being constructed::
+
+   >>> parent_parser = argparse.ArgumentParser(add_help=False)
+   >>> parent_parser.add_argument('--parent', type=int)
+
+   >>> foo_parser = argparse.ArgumentParser(parents=[parent_parser])
+   >>> foo_parser.add_argument('foo')
+   >>> foo_parser.parse_args(['--parent', '2', 'XXX'])
+   Namespace(foo='XXX', parent=2)
+
+   >>> bar_parser = argparse.ArgumentParser(parents=[parent_parser])
+   >>> bar_parser.add_argument('--bar')
+   >>> bar_parser.parse_args(['--bar', 'YYY'])
+   Namespace(bar='YYY', parent=None)
+
+Note that most parent parsers will specify ``add_help=False``.  Otherwise, the
+:class:`ArgumentParser` will see two ``-h/--help`` options (one in the parent
+and one in the child) and raise an error.
+
+
+formatter_class
+^^^^^^^^^^^^^^^
+
+:class:`ArgumentParser` objects allow the help formatting to be customized by
+specifying an alternate formatting class.  Currently, there are three such
+classes: :class:`argparse.RawDescriptionHelpFormatter`,
+:class:`argparse.RawTextHelpFormatter` and
+:class:`argparse.ArgumentDefaultsHelpFormatter`.  The first two allow more
+control over how textual descriptions are displayed, while the last
+automatically adds information about argument default values.
+
+By default, :class:`ArgumentParser` objects line-wrap the description_ and
+epilog_ texts in command-line help messages::
+
+   >>> parser = argparse.ArgumentParser(
+   ...     prog='PROG',
+   ...     description='''this description
+   ...         was indented weird
+   ...             but that is okay''',
+   ...     epilog='''
+   ...             likewise for this epilog whose whitespace will
+   ...         be cleaned up and whose words will be wrapped
+   ...         across a couple lines''')
+   >>> parser.print_help()
+   usage: PROG [-h]
+
+   this description was indented weird but that is okay
+
+   optional arguments:
+    -h, --help  show this help message and exit
+
+   likewise for this epilog whose whitespace will be cleaned up and whose words
+   will be wrapped across a couple lines
+
+Passing :class:`argparse.RawDescriptionHelpFormatter` as ``formatter_class=``
+indicates that description_ and epilog_ are already correctly formatted and
+should not be line-wrapped::
+
+   >>> parser = argparse.ArgumentParser(
+   ...     prog='PROG',
+   ...     formatter_class=argparse.RawDescriptionHelpFormatter,
+   ...     description=textwrap.dedent('''\
+   ...         Please do not mess up this text!
+   ...         --------------------------------
+   ...             I have indented it
+   ...             exactly the way
+   ...             I want it
+   ...         '''))
+   >>> parser.print_help()
+   usage: PROG [-h]
+
+   Please do not mess up this text!
+   --------------------------------
+      I have indented it
+      exactly the way
+      I want it
+
+   optional arguments:
+    -h, --help  show this help message and exit
+
+:class:`RawTextHelpFormatter` maintains whitespace for all sorts of help text
+including argument descriptions.
+
+The other formatter class available, :class:`ArgumentDefaultsHelpFormatter`,
+will add information about the default value of each of the arguments::
+
+   >>> parser = argparse.ArgumentParser(
+   ...     prog='PROG',
+   ...     formatter_class=argparse.ArgumentDefaultsHelpFormatter)
+   >>> parser.add_argument('--foo', type=int, default=42, help='FOO!')
+   >>> parser.add_argument('bar', nargs='*', default=[1, 2, 3], help='BAR!')
+   >>> parser.print_help()
+   usage: PROG [-h] [--foo FOO] [bar [bar ...]]
+
+   positional arguments:
+    bar         BAR! (default: [1, 2, 3])
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --foo FOO   FOO! (default: 42)
+
+
+conflict_handler
+^^^^^^^^^^^^^^^^
+
+:class:`ArgumentParser` objects do not allow two actions with the same option
+string.  By default, :class:`ArgumentParser` objects raises an exception if an
+attempt is made to create an argument with an option string that is already in
+use::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('-f', '--foo', help='old foo help')
+   >>> parser.add_argument('--foo', help='new foo help')
+   Traceback (most recent call last):
+    ..
+   ArgumentError: argument --foo: conflicting option string(s): --foo
+
+Sometimes (e.g. when using parents_) it may be useful to simply override any
+older arguments with the same option string.  To get this behavior, the value
+``'resolve'`` can be supplied to the ``conflict_handler=`` argument of
+:class:`ArgumentParser`::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG', conflict_handler='resolve')
+   >>> parser.add_argument('-f', '--foo', help='old foo help')
+   >>> parser.add_argument('--foo', help='new foo help')
+   >>> parser.print_help()
+   usage: PROG [-h] [-f FOO] [--foo FOO]
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    -f FOO      old foo help
+    --foo FOO   new foo help
+
+Note that :class:`ArgumentParser` objects only remove an action if all of its
+option strings are overridden.  So, in the example above, the old ``-f/--foo``
+action is retained as the ``-f`` action, because only the ``--foo`` option
+string was overridden.
+
+
+prog
+^^^^
+
+By default, :class:`ArgumentParser` objects uses ``sys.argv[0]`` to determine
+how to display the name of the program in help messages.  This default is almost
+always desirable because it will make the help messages match how the program was
+invoked on the command line.  For example, consider a file named
+``myprogram.py`` with the following code::
+
+   import argparse
+   parser = argparse.ArgumentParser()
+   parser.add_argument('--foo', help='foo help')
+   args = parser.parse_args()
+
+The help for this program will display ``myprogram.py`` as the program name
+(regardless of where the program was invoked from)::
+
+   $ python myprogram.py --help
+   usage: myprogram.py [-h] [--foo FOO]
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --foo FOO   foo help
+   $ cd ..
+   $ python subdir\myprogram.py --help
+   usage: myprogram.py [-h] [--foo FOO]
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --foo FOO   foo help
+
+To change this default behavior, another value can be supplied using the
+``prog=`` argument to :class:`ArgumentParser`::
+
+   >>> parser = argparse.ArgumentParser(prog='myprogram')
+   >>> parser.print_help()
+   usage: myprogram [-h]
+
+   optional arguments:
+    -h, --help  show this help message and exit
+
+Note that the program name, whether determined from ``sys.argv[0]`` or from the
+``prog=`` argument, is available to help messages using the ``%(prog)s`` format
+specifier.
+
+::
+
+   >>> parser = argparse.ArgumentParser(prog='myprogram')
+   >>> parser.add_argument('--foo', help='foo of the %(prog)s program')
+   >>> parser.print_help()
+   usage: myprogram [-h] [--foo FOO]
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --foo FOO   foo of the myprogram program
+
+
+usage
+^^^^^
+
+By default, :class:`ArgumentParser` calculates the usage message from the
+arguments it contains::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('--foo', nargs='?', help='foo help')
+   >>> parser.add_argument('bar', nargs='+', help='bar help')
+   >>> parser.print_help()
+   usage: PROG [-h] [--foo [FOO]] bar [bar ...]
+
+   positional arguments:
+    bar          bar help
+
+   optional arguments:
+    -h, --help   show this help message and exit
+    --foo [FOO]  foo help
+
+The default message can be overridden with the ``usage=`` keyword argument::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG', usage='%(prog)s [options]')
+   >>> parser.add_argument('--foo', nargs='?', help='foo help')
+   >>> parser.add_argument('bar', nargs='+', help='bar help')
+   >>> parser.print_help()
+   usage: PROG [options]
+
+   positional arguments:
+    bar          bar help
+
+   optional arguments:
+    -h, --help   show this help message and exit
+    --foo [FOO]  foo help
+
+The ``%(prog)s`` format specifier is available to fill in the program name in
+your usage messages.
+
+
+The add_argument() method
+-------------------------
+
+.. method:: ArgumentParser.add_argument(name or flags..., [action], [nargs], \
+                           [const], [default], [type], [choices], [required], \
+                           [help], [metavar], [dest])
+
+   Define how a single command line argument should be parsed.  Each parameter
+   has its own more detailed description below, but in short they are:
+
+   * `name or flags`_ - Either a name or a list of option strings, e.g. ``foo``
+     or ``-f, --foo``
+
+   * action_ - The basic type of action to be taken when this argument is
+     encountered at the command-line.
+
+   * nargs_ - The number of command-line arguments that should be consumed.
+
+   * const_ - A constant value required by some action_ and nargs_ selections.
+
+   * default_ - The value produced if the argument is absent from the
+     command-line.
+
+   * type_ - The type to which the command-line arg should be converted.
+
+   * choices_ - A container of the allowable values for the argument.
+
+   * required_ - Whether or not the command-line option may be omitted
+     (optionals only).
+
+   * help_ - A brief description of what the argument does.
+
+   * metavar_ - A name for the argument in usage messages.
+
+   * dest_ - The name of the attribute to be added to the object returned by
+     :meth:`parse_args`.
+
+The following sections describe how each of these are used.
+
+
+name or flags
+^^^^^^^^^^^^^
+
+The :meth:`add_argument` method must know whether an optional argument, like
+``-f`` or ``--foo``, or a positional argument, like a list of filenames, is
+expected.  The first arguments passed to :meth:`add_argument` must therefore be
+either a series of flags, or a simple argument name.  For example, an optional
+argument could be created like::
+
+   >>> parser.add_argument('-f', '--foo')
+
+while a positional argument could be created like::
+
+   >>> parser.add_argument('bar')
+
+When :meth:`parse_args` is called, optional arguments will be identified by the
+``-`` prefix, and the remaining arguments will be assumed to be positional::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('-f', '--foo')
+   >>> parser.add_argument('bar')
+   >>> parser.parse_args(['BAR'])
+   Namespace(bar='BAR', foo=None)
+   >>> parser.parse_args(['BAR', '--foo', 'FOO'])
+   Namespace(bar='BAR', foo='FOO')
+   >>> parser.parse_args(['--foo', 'FOO'])
+   usage: PROG [-h] [-f FOO] bar
+   PROG: error: too few arguments
+
+
+action
+^^^^^^
+
+:class:`ArgumentParser` objects associate command-line args with actions.  These
+actions can do just about anything with the command-line args associated with
+them, though most actions simply add an attribute to the object returned by
+:meth:`parse_args`.  The ``action`` keyword argument specifies how the
+command-line args should be handled. The supported actions are:
+
+* ``'store'`` - This just stores the argument's value.  This is the default
+   action. For example::
+
+    >>> parser = argparse.ArgumentParser()
+    >>> parser.add_argument('--foo')
+    >>> parser.parse_args('--foo 1'.split())
+    Namespace(foo='1')
+
+* ``'store_const'`` - This stores the value specified by the const_ keyword
+   argument.  (Note that the const_ keyword argument defaults to the rather
+   unhelpful ``None``.)  The ``'store_const'`` action is most commonly used with
+   optional arguments that specify some sort of flag.  For example::
+
+    >>> parser = argparse.ArgumentParser()
+    >>> parser.add_argument('--foo', action='store_const', const=42)
+    >>> parser.parse_args('--foo'.split())
+    Namespace(foo=42)
+
+* ``'store_true'`` and ``'store_false'`` - These store the values ``True`` and
+  ``False`` respectively.  These are special cases of ``'store_const'``.  For
+  example::
+
+    >>> parser = argparse.ArgumentParser()
+    >>> parser.add_argument('--foo', action='store_true')
+    >>> parser.add_argument('--bar', action='store_false')
+    >>> parser.parse_args('--foo --bar'.split())
+    Namespace(bar=False, foo=True)
+
+* ``'append'`` - This stores a list, and appends each argument value to the
+  list.  This is useful to allow an option to be specified multiple times.
+  Example usage::
+
+    >>> parser = argparse.ArgumentParser()
+    >>> parser.add_argument('--foo', action='append')
+    >>> parser.parse_args('--foo 1 --foo 2'.split())
+    Namespace(foo=['1', '2'])
+
+* ``'append_const'`` - This stores a list, and appends the value specified by
+  the const_ keyword argument to the list.  (Note that the const_ keyword
+  argument defaults to ``None``.)  The ``'append_const'`` action is typically
+  useful when multiple arguments need to store constants to the same list. For
+  example::
+
+    >>> parser = argparse.ArgumentParser()
+    >>> parser.add_argument('--str', dest='types', action='append_const', const=str)
+    >>> parser.add_argument('--int', dest='types', action='append_const', const=int)
+    >>> parser.parse_args('--str --int'.split())
+    Namespace(types=[<type 'str'>, <type 'int'>])
+
+* ``'version'`` - This expects a ``version=`` keyword argument in the
+  :meth:`add_argument` call, and prints version information and exits when
+  invoked.
+
+    >>> import argparse
+    >>> parser = argparse.ArgumentParser(prog='PROG')
+    >>> parser.add_argument('--version', action='version', version='%(prog)s 2.0')
+    >>> parser.parse_args(['--version'])
+    PROG 2.0
+
+You can also specify an arbitrary action by passing an object that implements
+the Action API.  The easiest way to do this is to extend
+:class:`argparse.Action`, supplying an appropriate ``__call__`` method.  The
+``__call__`` method should accept four parameters:
+
+* ``parser`` - The ArgumentParser object which contains this action.
+
+* ``namespace`` - The namespace object that will be returned by
+  :meth:`parse_args`.  Most actions add an attribute to this object.
+
+* ``values`` - The associated command-line args, with any type-conversions
+  applied.  (Type-conversions are specified with the type_ keyword argument to
+  :meth:`add_argument`.
+
+* ``option_string`` - The option string that was used to invoke this action.
+  The ``option_string`` argument is optional, and will be absent if the action
+  is associated with a positional argument.
+
+An example of a custom action::
+
+   >>> class FooAction(argparse.Action):
+   ...     def __call__(self, parser, namespace, values, option_string=None):
+   ...         print('%r %r %r' % (namespace, values, option_string))
+   ...         setattr(namespace, self.dest, values)
+   ...
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo', action=FooAction)
+   >>> parser.add_argument('bar', action=FooAction)
+   >>> args = parser.parse_args('1 --foo 2'.split())
+   Namespace(bar=None, foo=None) '1' None
+   Namespace(bar='1', foo=None) '2' '--foo'
+   >>> args
+   Namespace(bar='1', foo='2')
+
+
+nargs
+^^^^^
+
+ArgumentParser objects usually associate a single command-line argument with a
+single action to be taken.  The ``nargs`` keyword argument associates a
+different number of command-line arguments with a single action..  The supported
+values are:
+
+* N (an integer).  N args from the command-line will be gathered together into a
+  list.  For example::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> parser.add_argument('--foo', nargs=2)
+     >>> parser.add_argument('bar', nargs=1)
+     >>> parser.parse_args('c --foo a b'.split())
+     Namespace(bar=['c'], foo=['a', 'b'])
+
+  Note that ``nargs=1`` produces a list of one item.  This is different from
+  the default, in which the item is produced by itself.
+
+* ``'?'``. One arg will be consumed from the command-line if possible, and
+  produced as a single item.  If no command-line arg is present, the value from
+  default_ will be produced.  Note that for optional arguments, there is an
+  additional case - the option string is present but not followed by a
+  command-line arg.  In this case the value from const_ will be produced.  Some
+  examples to illustrate this::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> parser.add_argument('--foo', nargs='?', const='c', default='d')
+     >>> parser.add_argument('bar', nargs='?', default='d')
+     >>> parser.parse_args('XX --foo YY'.split())
+     Namespace(bar='XX', foo='YY')
+     >>> parser.parse_args('XX --foo'.split())
+     Namespace(bar='XX', foo='c')
+     >>> parser.parse_args(''.split())
+     Namespace(bar='d', foo='d')
+
+  One of the more common uses of ``nargs='?'`` is to allow optional input and
+  output files::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> parser.add_argument('infile', nargs='?', type=argparse.FileType('r'),
+     ...                     default=sys.stdin)
+     >>> parser.add_argument('outfile', nargs='?', type=argparse.FileType('w'),
+     ...                     default=sys.stdout)
+     >>> parser.parse_args(['input.txt', 'output.txt'])
+     Namespace(infile=<_io.TextIOWrapper name='input.txt' encoding='UTF-8'>,
+               outfile=<_io.TextIOWrapper name='output.txt' encoding='UTF-8'>)
+     >>> parser.parse_args([])
+     Namespace(infile=<_io.TextIOWrapper name='<stdin>' encoding='UTF-8'>,
+               outfile=<_io.TextIOWrapper name='<stdout>' encoding='UTF-8'>)
+
+* ``'*'``.  All command-line args present are gathered into a list.  Note that
+  it generally doesn't make much sense to have more than one positional argument
+  with ``nargs='*'``, but multiple optional arguments with ``nargs='*'`` is
+  possible.  For example::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> parser.add_argument('--foo', nargs='*')
+     >>> parser.add_argument('--bar', nargs='*')
+     >>> parser.add_argument('baz', nargs='*')
+     >>> parser.parse_args('a b --foo x y --bar 1 2'.split())
+     Namespace(bar=['1', '2'], baz=['a', 'b'], foo=['x', 'y'])
+
+* ``'+'``. Just like ``'*'``, all command-line args present are gathered into a
+  list.  Additionally, an error message will be generated if there wasn't at
+  least one command-line arg present.  For example::
+
+     >>> parser = argparse.ArgumentParser(prog='PROG')
+     >>> parser.add_argument('foo', nargs='+')
+     >>> parser.parse_args('a b'.split())
+     Namespace(foo=['a', 'b'])
+     >>> parser.parse_args(''.split())
+     usage: PROG [-h] foo [foo ...]
+     PROG: error: too few arguments
+
+If the ``nargs`` keyword argument is not provided, the number of args consumed
+is determined by the action_.  Generally this means a single command-line arg
+will be consumed and a single item (not a list) will be produced.
+
+
+const
+^^^^^
+
+The ``const`` argument of :meth:`add_argument` is used to hold constant values
+that are not read from the command line but are required for the various
+ArgumentParser actions.  The two most common uses of it are:
+
+* When :meth:`add_argument` is called with ``action='store_const'`` or
+  ``action='append_const'``.  These actions add the ``const`` value to one of
+  the attributes of the object returned by :meth:`parse_args`.  See the action_
+  description for examples.
+
+* When :meth:`add_argument` is called with option strings (like ``-f`` or
+  ``--foo``) and ``nargs='?'``.  This creates an optional argument that can be
+  followed by zero or one command-line args.  When parsing the command-line, if
+  the option string is encountered with no command-line arg following it, the
+  value of ``const`` will be assumed instead. See the nargs_ description for
+  examples.
+
+The ``const`` keyword argument defaults to ``None``.
+
+
+default
+^^^^^^^
+
+All optional arguments and some positional arguments may be omitted at the
+command-line.  The ``default`` keyword argument of :meth:`add_argument`, whose
+value defaults to ``None``, specifies what value should be used if the
+command-line arg is not present.  For optional arguments, the ``default`` value
+is used when the option string was not present at the command line::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo', default=42)
+   >>> parser.parse_args('--foo 2'.split())
+   Namespace(foo='2')
+   >>> parser.parse_args(''.split())
+   Namespace(foo=42)
+
+For positional arguments with nargs_ ``='?'`` or ``'*'``, the ``default`` value
+is used when no command-line arg was present::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('foo', nargs='?', default=42)
+   >>> parser.parse_args('a'.split())
+   Namespace(foo='a')
+   >>> parser.parse_args(''.split())
+   Namespace(foo=42)
+
+
+Providing ``default=argparse.SUPPRESS`` causes no attribute to be added if the
+command-line argument was not present.::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo', default=argparse.SUPPRESS)
+   >>> parser.parse_args([])
+   Namespace()
+   >>> parser.parse_args(['--foo', '1'])
+   Namespace(foo='1')
+
+
+type
+^^^^
+
+By default, ArgumentParser objects read command-line args in as simple strings.
+However, quite often the command-line string should instead be interpreted as
+another type, like a :class:`float` or :class:`int`.  The ``type`` keyword
+argument of :meth:`add_argument` allows any necessary type-checking and
+type-conversions to be performed.  Common built-in types and functions can be
+used directly as the value of the ``type`` argument::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('foo', type=int)
+   >>> parser.add_argument('bar', type=open)
+   >>> parser.parse_args('2 temp.txt'.split())
+   Namespace(bar=<_io.TextIOWrapper name='temp.txt' encoding='UTF-8'>, foo=2)
+
+To ease the use of various types of files, the argparse module provides the
+factory FileType which takes the ``mode=`` and ``bufsize=`` arguments of the
+:func:`open` function.  For example, ``FileType('w')`` can be used to create a
+writable file::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('bar', type=argparse.FileType('w'))
+   >>> parser.parse_args(['out.txt'])
+   Namespace(bar=<_io.TextIOWrapper name='out.txt' encoding='UTF-8'>)
+
+``type=`` can take any callable that takes a single string argument and returns
+the type-converted value::
+
+   >>> def perfect_square(string):
+   ...     value = int(string)
+   ...     sqrt = math.sqrt(value)
+   ...     if sqrt != int(sqrt):
+   ...         msg = "%r is not a perfect square" % string
+   ...         raise argparse.ArgumentTypeError(msg)
+   ...     return value
+   ...
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('foo', type=perfect_square)
+   >>> parser.parse_args('9'.split())
+   Namespace(foo=9)
+   >>> parser.parse_args('7'.split())
+   usage: PROG [-h] foo
+   PROG: error: argument foo: '7' is not a perfect square
+
+The choices_ keyword argument may be more convenient for type checkers that
+simply check against a range of values::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('foo', type=int, choices=range(5, 10))
+   >>> parser.parse_args('7'.split())
+   Namespace(foo=7)
+   >>> parser.parse_args('11'.split())
+   usage: PROG [-h] {5,6,7,8,9}
+   PROG: error: argument foo: invalid choice: 11 (choose from 5, 6, 7, 8, 9)
+
+See the choices_ section for more details.
+
+
+choices
+^^^^^^^
+
+Some command-line args should be selected from a restricted set of values.
+These can be handled by passing a container object as the ``choices`` keyword
+argument to :meth:`add_argument`.  When the command-line is parsed, arg values
+will be checked, and an error message will be displayed if the arg was not one
+of the acceptable values::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('foo', choices='abc')
+   >>> parser.parse_args('c'.split())
+   Namespace(foo='c')
+   >>> parser.parse_args('X'.split())
+   usage: PROG [-h] {a,b,c}
+   PROG: error: argument foo: invalid choice: 'X' (choose from 'a', 'b', 'c')
+
+Note that inclusion in the ``choices`` container is checked after any type_
+conversions have been performed, so the type of the objects in the ``choices``
+container should match the type_ specified::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('foo', type=complex, choices=[1, 1j])
+   >>> parser.parse_args('1j'.split())
+   Namespace(foo=1j)
+   >>> parser.parse_args('-- -4'.split())
+   usage: PROG [-h] {1,1j}
+   PROG: error: argument foo: invalid choice: (-4+0j) (choose from 1, 1j)
+
+Any object that supports the ``in`` operator can be passed as the ``choices``
+value, so :class:`dict` objects, :class:`set` objects, custom containers,
+etc. are all supported.
+
+
+required
+^^^^^^^^
+
+In general, the argparse module assumes that flags like ``-f`` and ``--bar``
+indicate *optional* arguments, which can always be omitted at the command-line.
+To make an option *required*, ``True`` can be specified for the ``required=``
+keyword argument to :meth:`add_argument`::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo', required=True)
+   >>> parser.parse_args(['--foo', 'BAR'])
+   Namespace(foo='BAR')
+   >>> parser.parse_args([])
+   usage: argparse.py [-h] [--foo FOO]
+   argparse.py: error: option --foo is required
+
+As the example shows, if an option is marked as ``required``, :meth:`parse_args`
+will report an error if that option is not present at the command line.
+
+.. note::
+
+    Required options are generally considered bad form because users expect
+    *options* to be *optional*, and thus they should be avoided when possible.
+
+
+help
+^^^^
+
+The ``help`` value is a string containing a brief description of the argument.
+When a user requests help (usually by using ``-h`` or ``--help`` at the
+command-line), these ``help`` descriptions will be displayed with each
+argument::
+
+   >>> parser = argparse.ArgumentParser(prog='frobble')
+   >>> parser.add_argument('--foo', action='store_true',
+   ...         help='foo the bars before frobbling')
+   >>> parser.add_argument('bar', nargs='+',
+   ...         help='one of the bars to be frobbled')
+   >>> parser.parse_args('-h'.split())
+   usage: frobble [-h] [--foo] bar [bar ...]
+
+   positional arguments:
+    bar     one of the bars to be frobbled
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --foo   foo the bars before frobbling
+
+The ``help`` strings can include various format specifiers to avoid repetition
+of things like the program name or the argument default_.  The available
+specifiers include the program name, ``%(prog)s`` and most keyword arguments to
+:meth:`add_argument`, e.g. ``%(default)s``, ``%(type)s``, etc.::
+
+   >>> parser = argparse.ArgumentParser(prog='frobble')
+   >>> parser.add_argument('bar', nargs='?', type=int, default=42,
+   ...         help='the bar to %(prog)s (default: %(default)s)')
+   >>> parser.print_help()
+   usage: frobble [-h] [bar]
+
+   positional arguments:
+    bar     the bar to frobble (default: 42)
+
+   optional arguments:
+    -h, --help  show this help message and exit
+
+
+metavar
+^^^^^^^
+
+When :class:`ArgumentParser` generates help messages, it need some way to refer
+to each expected argument.  By default, ArgumentParser objects use the dest_
+value as the "name" of each object.  By default, for positional argument
+actions, the dest_ value is used directly, and for optional argument actions,
+the dest_ value is uppercased.  So, a single positional argument with
+``dest='bar'`` will that argument will be referred to as ``bar``. A single
+optional argument ``--foo`` that should be followed by a single command-line arg
+will be referred to as ``FOO``.  An example::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo')
+   >>> parser.add_argument('bar')
+   >>> parser.parse_args('X --foo Y'.split())
+   Namespace(bar='X', foo='Y')
+   >>> parser.print_help()
+   usage:  [-h] [--foo FOO] bar
+
+   positional arguments:
+    bar
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --foo FOO
+
+An alternative name can be specified with ``metavar``::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo', metavar='YYY')
+   >>> parser.add_argument('bar', metavar='XXX')
+   >>> parser.parse_args('X --foo Y'.split())
+   Namespace(bar='X', foo='Y')
+   >>> parser.print_help()
+   usage:  [-h] [--foo YYY] XXX
+
+   positional arguments:
+    XXX
+
+   optional arguments:
+    -h, --help  show this help message and exit
+    --foo YYY
+
+Note that ``metavar`` only changes the *displayed* name - the name of the
+attribute on the :meth:`parse_args` object is still determined by the dest_
+value.
+
+Different values of ``nargs`` may cause the metavar to be used multiple times.
+Providing a tuple to ``metavar`` specifies a different display for each of the
+arguments::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('-x', nargs=2)
+   >>> parser.add_argument('--foo', nargs=2, metavar=('bar', 'baz'))
+   >>> parser.print_help()
+   usage: PROG [-h] [-x X X] [--foo bar baz]
+
+   optional arguments:
+    -h, --help     show this help message and exit
+    -x X X
+    --foo bar baz
+
+
+dest
+^^^^
+
+Most :class:`ArgumentParser` actions add some value as an attribute of the
+object returned by :meth:`parse_args`.  The name of this attribute is determined
+by the ``dest`` keyword argument of :meth:`add_argument`.  For positional
+argument actions, ``dest`` is normally supplied as the first argument to
+:meth:`add_argument`::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('bar')
+   >>> parser.parse_args('XXX'.split())
+   Namespace(bar='XXX')
+
+For optional argument actions, the value of ``dest`` is normally inferred from
+the option strings.  :class:`ArgumentParser` generates the value of ``dest`` by
+taking the first long option string and stripping away the initial ``'--'``
+string.  If no long option strings were supplied, ``dest`` will be derived from
+the first short option string by stripping the initial ``'-'`` character.  Any
+internal ``'-'`` characters will be converted to ``'_'`` characters to make sure
+the string is a valid attribute name.  The examples below illustrate this
+behavior::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('-f', '--foo-bar', '--foo')
+   >>> parser.add_argument('-x', '-y')
+   >>> parser.parse_args('-f 1 -x 2'.split())
+   Namespace(foo_bar='1', x='2')
+   >>> parser.parse_args('--foo 1 -y 2'.split())
+   Namespace(foo_bar='1', x='2')
+
+``dest`` allows a custom attribute name to be provided::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo', dest='bar')
+   >>> parser.parse_args('--foo XXX'.split())
+   Namespace(bar='XXX')
+
+
+The parse_args() method
+-----------------------
+
+.. method:: ArgumentParser.parse_args(args=None, namespace=None)
+
+   Convert argument strings to objects and assign them as attributes of the
+   namespace.  Return the populated namespace.
+
+   Previous calls to :meth:`add_argument` determine exactly what objects are
+   created and how they are assigned. See the documentation for
+   :meth:`add_argument` for details.
+
+   By default, the arg strings are taken from :data:`sys.argv`, and a new empty
+   :class:`Namespace` object is created for the attributes.
+
+
+Option value syntax
+^^^^^^^^^^^^^^^^^^^
+
+The :meth:`parse_args` method supports several ways of specifying the value of
+an option (if it takes one).  In the simplest case, the option and its value are
+passed as two separate arguments::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('-x')
+   >>> parser.add_argument('--foo')
+   >>> parser.parse_args('-x X'.split())
+   Namespace(foo=None, x='X')
+   >>> parser.parse_args('--foo FOO'.split())
+   Namespace(foo='FOO', x=None)
+
+For long options (options with names longer than a single character), the option
+and value can also be passed as a single command line argument, using ``=`` to
+separate them::
+
+   >>> parser.parse_args('--foo=FOO'.split())
+   Namespace(foo='FOO', x=None)
+
+For short options (options only one character long), the option and its value
+can be concatenated::
+
+   >>> parser.parse_args('-xX'.split())
+   Namespace(foo=None, x='X')
+
+Several short options can be joined together, using only a single ``-`` prefix,
+as long as only the last option (or none of them) requires a value::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('-x', action='store_true')
+   >>> parser.add_argument('-y', action='store_true')
+   >>> parser.add_argument('-z')
+   >>> parser.parse_args('-xyzZ'.split())
+   Namespace(x=True, y=True, z='Z')
+
+
+Invalid arguments
+^^^^^^^^^^^^^^^^^
+
+While parsing the command-line, ``parse_args`` checks for a variety of errors,
+including ambiguous options, invalid types, invalid options, wrong number of
+positional arguments, etc.  When it encounters such an error, it exits and
+prints the error along with a usage message::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('--foo', type=int)
+   >>> parser.add_argument('bar', nargs='?')
+
+   >>> # invalid type
+   >>> parser.parse_args(['--foo', 'spam'])
+   usage: PROG [-h] [--foo FOO] [bar]
+   PROG: error: argument --foo: invalid int value: 'spam'
+
+   >>> # invalid option
+   >>> parser.parse_args(['--bar'])
+   usage: PROG [-h] [--foo FOO] [bar]
+   PROG: error: no such option: --bar
+
+   >>> # wrong number of arguments
+   >>> parser.parse_args(['spam', 'badger'])
+   usage: PROG [-h] [--foo FOO] [bar]
+   PROG: error: extra arguments found: badger
+
+
+Arguments containing ``"-"``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The ``parse_args`` method attempts to give errors whenever the user has clearly
+made a mistake, but some situations are inherently ambiguous.  For example, the
+command-line arg ``'-1'`` could either be an attempt to specify an option or an
+attempt to provide a positional argument.  The ``parse_args`` method is cautious
+here: positional arguments may only begin with ``'-'`` if they look like
+negative numbers and there are no options in the parser that look like negative
+numbers::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('-x')
+   >>> parser.add_argument('foo', nargs='?')
+
+   >>> # no negative number options, so -1 is a positional argument
+   >>> parser.parse_args(['-x', '-1'])
+   Namespace(foo=None, x='-1')
+
+   >>> # no negative number options, so -1 and -5 are positional arguments
+   >>> parser.parse_args(['-x', '-1', '-5'])
+   Namespace(foo='-5', x='-1')
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('-1', dest='one')
+   >>> parser.add_argument('foo', nargs='?')
+
+   >>> # negative number options present, so -1 is an option
+   >>> parser.parse_args(['-1', 'X'])
+   Namespace(foo=None, one='X')
+
+   >>> # negative number options present, so -2 is an option
+   >>> parser.parse_args(['-2'])
+   usage: PROG [-h] [-1 ONE] [foo]
+   PROG: error: no such option: -2
+
+   >>> # negative number options present, so both -1s are options
+   >>> parser.parse_args(['-1', '-1'])
+   usage: PROG [-h] [-1 ONE] [foo]
+   PROG: error: argument -1: expected one argument
+
+If you have positional arguments that must begin with ``'-'`` and don't look
+like negative numbers, you can insert the pseudo-argument ``'--'`` which tells
+``parse_args`` that everything after that is a positional argument::
+
+   >>> parser.parse_args(['--', '-f'])
+   Namespace(foo='-f', one=None)
+
+
+Argument abbreviations
+^^^^^^^^^^^^^^^^^^^^^^
+
+The :meth:`parse_args` method allows long options to be abbreviated if the
+abbreviation is unambiguous::
+
+   >>> parser = argparse.ArgumentParser(prog='PROG')
+   >>> parser.add_argument('-bacon')
+   >>> parser.add_argument('-badger')
+   >>> parser.parse_args('-bac MMM'.split())
+   Namespace(bacon='MMM', badger=None)
+   >>> parser.parse_args('-bad WOOD'.split())
+   Namespace(bacon=None, badger='WOOD')
+   >>> parser.parse_args('-ba BA'.split())
+   usage: PROG [-h] [-bacon BACON] [-badger BADGER]
+   PROG: error: ambiguous option: -ba could match -badger, -bacon
+
+An error is produced for arguments that could produce more than one options.
+
+
+Beyond ``sys.argv``
+^^^^^^^^^^^^^^^^^^^
+
+Sometimes it may be useful to have an ArgumentParser parse args other than those
+of :data:`sys.argv`.  This can be accomplished by passing a list of strings to
+``parse_args``.  This is useful for testing at the interactive prompt::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument(
+   ...     'integers', metavar='int', type=int, choices=range(10),
+   ...  nargs='+', help='an integer in the range 0..9')
+   >>> parser.add_argument(
+   ...     '--sum', dest='accumulate', action='store_const', const=sum,
+   ...   default=max, help='sum the integers (default: find the max)')
+   >>> parser.parse_args(['1', '2', '3', '4'])
+   Namespace(accumulate=<built-in function max>, integers=[1, 2, 3, 4])
+   >>> parser.parse_args('1 2 3 4 --sum'.split())
+   Namespace(accumulate=<built-in function sum>, integers=[1, 2, 3, 4])
+
+
+Custom namespaces
+^^^^^^^^^^^^^^^^^
+
+It may also be useful to have an :class:`ArgumentParser` assign attributes to an
+already existing object, rather than the newly-created :class:`Namespace` object
+that is normally used.  This can be achieved by specifying the ``namespace=``
+keyword argument::
+
+   >>> class C:
+   ...     pass
+   ...
+   >>> c = C()
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo')
+   >>> parser.parse_args(args=['--foo', 'BAR'], namespace=c)
+   >>> c.foo
+   'BAR'
+
+
+Other utilities
+---------------
+
+Sub-commands
+^^^^^^^^^^^^
+
+.. method:: ArgumentParser.add_subparsers()
+
+   Many programs split up their functionality into a number of sub-commands,
+   for example, the ``svn`` program can invoke sub-commands like ``svn
+   checkout``, ``svn update``, and ``svn commit``.  Splitting up functionality
+   this way can be a particularly good idea when a program performs several
+   different functions which require different kinds of command-line arguments.
+   :class:`ArgumentParser` supports the creation of such sub-commands with the
+   :meth:`add_subparsers` method.  The :meth:`add_subparsers` method is normally
+   called with no arguments and returns an special action object.  This object
+   has a single method, ``add_parser``, which takes a command name and any
+   :class:`ArgumentParser` constructor arguments, and returns an
+   :class:`ArgumentParser` object that can be modified as usual.
+
+   Some example usage::
+
+     >>> # create the top-level parser
+     >>> parser = argparse.ArgumentParser(prog='PROG')
+     >>> parser.add_argument('--foo', action='store_true', help='foo help')
+     >>> subparsers = parser.add_subparsers(help='sub-command help')
+     >>>
+     >>> # create the parser for the "a" command
+     >>> parser_a = subparsers.add_parser('a', help='a help')
+     >>> parser_a.add_argument('bar', type=int, help='bar help')
+     >>>
+     >>> # create the parser for the "b" command
+     >>> parser_b = subparsers.add_parser('b', help='b help')
+     >>> parser_b.add_argument('--baz', choices='XYZ', help='baz help')
+     >>>
+     >>> # parse some arg lists
+     >>> parser.parse_args(['a', '12'])
+     Namespace(bar=12, foo=False)
+     >>> parser.parse_args(['--foo', 'b', '--baz', 'Z'])
+     Namespace(baz='Z', foo=True)
+
+   Note that the object returned by :meth:`parse_args` will only contain
+   attributes for the main parser and the subparser that was selected by the
+   command line (and not any other subparsers).  So in the example above, when
+   the ``"a"`` command is specified, only the ``foo`` and ``bar`` attributes are
+   present, and when the ``"b"`` command is specified, only the ``foo`` and
+   ``baz`` attributes are present.
+
+   Similarly, when a help message is requested from a subparser, only the help
+   for that particular parser will be printed.  The help message will not
+   include parent parser or sibling parser messages.  (A help message for each
+   subparser command, however, can be given by supplying the ``help=`` argument
+   to ``add_parser`` as above.)
+
+   ::
+
+     >>> parser.parse_args(['--help'])
+     usage: PROG [-h] [--foo] {a,b} ...
+
+     positional arguments:
+       {a,b}   sub-command help
+     a     a help
+     b     b help
+
+     optional arguments:
+       -h, --help  show this help message and exit
+       --foo   foo help
+
+     >>> parser.parse_args(['a', '--help'])
+     usage: PROG a [-h] bar
+
+     positional arguments:
+       bar     bar help
+
+     optional arguments:
+       -h, --help  show this help message and exit
+
+     >>> parser.parse_args(['b', '--help'])
+     usage: PROG b [-h] [--baz {X,Y,Z}]
+
+     optional arguments:
+       -h, --help     show this help message and exit
+       --baz {X,Y,Z}  baz help
+
+   The :meth:`add_subparsers` method also supports ``title`` and ``description``
+   keyword arguments.  When either is present, the subparser's commands will
+   appear in their own group in the help output.  For example::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> subparsers = parser.add_subparsers(title='subcommands',
+     ...                                    description='valid subcommands',
+     ...                                    help='additional help')
+     >>> subparsers.add_parser('foo')
+     >>> subparsers.add_parser('bar')
+     >>> parser.parse_args(['-h'])
+     usage:  [-h] {foo,bar} ...
+
+     optional arguments:
+       -h, --help  show this help message and exit
+
+     subcommands:
+       valid subcommands
+
+       {foo,bar}   additional help
+
+   Furthermore, ``add_parser`` supports an additional ``aliases`` argument,
+   which allows multiple strings to refer to the same subparser. This example,
+   like ``svn``, aliases ``co`` as a shorthand for ``checkout``::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> subparsers = parser.add_subparsers()
+     >>> checkout = subparsers.add_parser('checkout', aliases=['co'])
+     >>> checkout.add_argument('foo')
+     >>> parser.parse_args(['co', 'bar'])
+     Namespace(foo='bar')
+
+   One particularly effective way of handling sub-commands is to combine the use
+   of the :meth:`add_subparsers` method with calls to :meth:`set_defaults` so
+   that each subparser knows which Python function it should execute.  For
+   example::
+
+     >>> # sub-command functions
+     >>> def foo(args):
+     ...     print(args.x * args.y)
+     ...
+     >>> def bar(args):
+     ...     print('((%s))' % args.z)
+     ...
+     >>> # create the top-level parser
+     >>> parser = argparse.ArgumentParser()
+     >>> subparsers = parser.add_subparsers()
+     >>>
+     >>> # create the parser for the "foo" command
+     >>> parser_foo = subparsers.add_parser('foo')
+     >>> parser_foo.add_argument('-x', type=int, default=1)
+     >>> parser_foo.add_argument('y', type=float)
+     >>> parser_foo.set_defaults(func=foo)
+     >>>
+     >>> # create the parser for the "bar" command
+     >>> parser_bar = subparsers.add_parser('bar')
+     >>> parser_bar.add_argument('z')
+     >>> parser_bar.set_defaults(func=bar)
+     >>>
+     >>> # parse the args and call whatever function was selected
+     >>> args = parser.parse_args('foo 1 -x 2'.split())
+     >>> args.func(args)
+     2.0
+     >>>
+     >>> # parse the args and call whatever function was selected
+     >>> args = parser.parse_args('bar XYZYX'.split())
+     >>> args.func(args)
+     ((XYZYX))
+
+   This way, you can let :meth:`parse_args` do the job of calling the
+   appropriate function after argument parsing is complete.  Associating
+   functions with actions like this is typically the easiest way to handle the
+   different actions for each of your subparsers.  However, if it is necessary
+   to check the name of the subparser that was invoked, the ``dest`` keyword
+   argument to the :meth:`add_subparsers` call will work::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> subparsers = parser.add_subparsers(dest='subparser_name')
+     >>> subparser1 = subparsers.add_parser('1')
+     >>> subparser1.add_argument('-x')
+     >>> subparser2 = subparsers.add_parser('2')
+     >>> subparser2.add_argument('y')
+     >>> parser.parse_args(['2', 'frobble'])
+     Namespace(subparser_name='2', y='frobble')
+
+
+FileType objects
+^^^^^^^^^^^^^^^^
+
+.. class:: FileType(mode='r', bufsize=None)
+
+   The :class:`FileType` factory creates objects that can be passed to the type
+   argument of :meth:`ArgumentParser.add_argument`.  Arguments that have
+   :class:`FileType` objects as their type will open command-line args as files
+   with the requested modes and buffer sizes:
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--output', type=argparse.FileType('wb', 0))
+   >>> parser.parse_args(['--output', 'out'])
+   Namespace(output=<_io.BufferedWriter name='out'>)
+
+   FileType objects understand the pseudo-argument ``'-'`` and automatically
+   convert this into ``sys.stdin`` for readable :class:`FileType` objects and
+   ``sys.stdout`` for writable :class:`FileType` objects:
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('infile', type=argparse.FileType('r'))
+   >>> parser.parse_args(['-'])
+   Namespace(infile=<_io.TextIOWrapper name='<stdin>' encoding='UTF-8'>)
+
+
+Argument groups
+^^^^^^^^^^^^^^^
+
+.. method:: ArgumentParser.add_argument_group(title=None, description=None)
+
+   By default, :class:`ArgumentParser` groups command-line arguments into
+   "positional arguments" and "optional arguments" when displaying help
+   messages. When there is a better conceptual grouping of arguments than this
+   default one, appropriate groups can be created using the
+   :meth:`add_argument_group` method::
+
+     >>> parser = argparse.ArgumentParser(prog='PROG', add_help=False)
+     >>> group = parser.add_argument_group('group')
+     >>> group.add_argument('--foo', help='foo help')
+     >>> group.add_argument('bar', help='bar help')
+     >>> parser.print_help()
+     usage: PROG [--foo FOO] bar
+
+     group:
+       bar    bar help
+       --foo FOO  foo help
+
+   The :meth:`add_argument_group` method returns an argument group object which
+   has an :meth:`~ArgumentParser.add_argument` method just like a regular
+   :class:`ArgumentParser`.  When an argument is added to the group, the parser
+   treats it just like a normal argument, but displays the argument in a
+   separate group for help messages.  The :meth:`add_argument_group` method
+   accepts *title* and *description* arguments which can be used to
+   customize this display::
+
+     >>> parser = argparse.ArgumentParser(prog='PROG', add_help=False)
+     >>> group1 = parser.add_argument_group('group1', 'group1 description')
+     >>> group1.add_argument('foo', help='foo help')
+     >>> group2 = parser.add_argument_group('group2', 'group2 description')
+     >>> group2.add_argument('--bar', help='bar help')
+     >>> parser.print_help()
+     usage: PROG [--bar BAR] foo
+
+     group1:
+       group1 description
+
+       foo    foo help
+
+     group2:
+       group2 description
+
+       --bar BAR  bar help
+
+   Note that any arguments not your user defined groups will end up back in the
+   usual "positional arguments" and "optional arguments" sections.
+
+
+Mutual exclusion
+^^^^^^^^^^^^^^^^
+
+.. method:: add_mutually_exclusive_group(required=False)
+
+   Create a mutually exclusive group. argparse will make sure that only one of
+   the arguments in the mutually exclusive group was present on the command
+   line::
+
+     >>> parser = argparse.ArgumentParser(prog='PROG')
+     >>> group = parser.add_mutually_exclusive_group()
+     >>> group.add_argument('--foo', action='store_true')
+     >>> group.add_argument('--bar', action='store_false')
+     >>> parser.parse_args(['--foo'])
+     Namespace(bar=True, foo=True)
+     >>> parser.parse_args(['--bar'])
+     Namespace(bar=False, foo=False)
+     >>> parser.parse_args(['--foo', '--bar'])
+     usage: PROG [-h] [--foo | --bar]
+     PROG: error: argument --bar: not allowed with argument --foo
+
+   The :meth:`add_mutually_exclusive_group` method also accepts a *required*
+   argument, to indicate that at least one of the mutually exclusive arguments
+   is required::
+
+     >>> parser = argparse.ArgumentParser(prog='PROG')
+     >>> group = parser.add_mutually_exclusive_group(required=True)
+     >>> group.add_argument('--foo', action='store_true')
+     >>> group.add_argument('--bar', action='store_false')
+     >>> parser.parse_args([])
+     usage: PROG [-h] (--foo | --bar)
+     PROG: error: one of the arguments --foo --bar is required
+
+   Note that currently mutually exclusive argument groups do not support the
+   *title* and *description* arguments of :meth:`add_argument_group`.
+
+
+Parser defaults
+^^^^^^^^^^^^^^^
+
+.. method:: ArgumentParser.set_defaults(**kwargs)
+
+   Most of the time, the attributes of the object returned by :meth:`parse_args`
+   will be fully determined by inspecting the command-line args and the argument
+   actions.  :meth:`ArgumentParser.set_defaults` allows some additional
+   attributes that are determined without any inspection of the command-line to
+   be added::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> parser.add_argument('foo', type=int)
+     >>> parser.set_defaults(bar=42, baz='badger')
+     >>> parser.parse_args(['736'])
+     Namespace(bar=42, baz='badger', foo=736)
+
+   Note that parser-level defaults always override argument-level defaults::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> parser.add_argument('--foo', default='bar')
+     >>> parser.set_defaults(foo='spam')
+     >>> parser.parse_args([])
+     Namespace(foo='spam')
+
+   Parser-level defaults can be particularly useful when working with multiple
+   parsers.  See the :meth:`~ArgumentParser.add_subparsers` method for an
+   example of this type.
+
+.. method:: ArgumentParser.get_default(dest)
+
+   Get the default value for a namespace attribute, as set by either
+   :meth:`~ArgumentParser.add_argument` or by
+   :meth:`~ArgumentParser.set_defaults`::
+
+     >>> parser = argparse.ArgumentParser()
+     >>> parser.add_argument('--foo', default='badger')
+     >>> parser.get_default('foo')
+     'badger'
+
+
+Printing help
+^^^^^^^^^^^^^
+
+In most typical applications, :meth:`parse_args` will take care of formatting
+and printing any usage or error messages.  However, several formatting methods
+are available:
+
+.. method:: ArgumentParser.print_usage(file=None)
+
+   Print a brief description of how the :class:`ArgumentParser` should be
+   invoked on the command line.  If *file* is ``None``, :data:`sys.stdout` is
+   assumed.
+
+.. method:: ArgumentParser.print_help(file=None)
+
+   Print a help message, including the program usage and information about the
+   arguments registered with the :class:`ArgumentParser`.  If *file* is
+   ``None``, :data:`sys.stdout` is assumed.
+
+There are also variants of these methods that simply return a string instead of
+printing it:
+
+.. method:: ArgumentParser.format_usage()
+
+   Return a string containing a brief description of how the
+   :class:`ArgumentParser` should be invoked on the command line.
+
+.. method:: ArgumentParser.format_help()
+
+   Return a string containing a help message, including the program usage and
+   information about the arguments registered with the :class:`ArgumentParser`.
+
+
+Partial parsing
+^^^^^^^^^^^^^^^
+
+.. method:: ArgumentParser.parse_known_args(args=None, namespace=None)
+
+Sometimes a script may only parse a few of the command line arguments, passing
+the remaining arguments on to another script or program. In these cases, the
+:meth:`parse_known_args` method can be useful.  It works much like
+:meth:`~ArgumentParser.parse_args` except that it does not produce an error when
+extra arguments are present.  Instead, it returns a two item tuple containing
+the populated namespace and the list of remaining argument strings.
+
+::
+
+   >>> parser = argparse.ArgumentParser()
+   >>> parser.add_argument('--foo', action='store_true')
+   >>> parser.add_argument('bar')
+   >>> parser.parse_known_args(['--foo', '--badger', 'BAR', 'spam'])
+   (Namespace(bar='BAR', foo=True), ['--badger', 'spam'])
+
+
+Customizing file parsing
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. method:: ArgumentParser.convert_arg_line_to_args(arg_line)
+
+   Arguments that are read from a file (see the *fromfile_prefix_chars*
+   keyword argument to the :class:`ArgumentParser` constructor) are read one
+   argument per line. :meth:`convert_arg_line_to_args` can be overriden for
+   fancier reading.
+
+   This method takes a single argument *arg_line* which is a string read from
+   the argument file.  It returns a list of arguments parsed from this string.
+   The method is called once per line read from the argument file, in order.
+
+   A useful override of this method is one that treats each space-separated word
+   as an argument::
+
+    def convert_arg_line_to_args(self, arg_line):
+        for arg in arg_line.split():

+Upgrading optparse code
+-----------------------
+
+Originally, the argparse module had attempted to maintain compatibility with
+optparse.  However, optparse was difficult to extend transparently, particularly
+with the changes required to support the new ``nargs=`` specifiers and better
+usage messages.  When most everything in optparse had either been copy-pasted
+over or monkey-patched, it no longer seemed practical to try to maintain the
+backwards compatibility.
+
+A partial upgrade path from optparse to argparse:
+
+* Replace all ``add_option()`` calls with :meth:`ArgumentParser.add_argument`
+  calls.
+
+* Replace ``options, args = parser.parse_args()`` with ``args =
+  parser.parse_args()`` and add additional :meth:`ArgumentParser.add_argument`
+  calls for the positional arguments.
+
+* Replace callback actions and the ``callback_*`` keyword arguments with
+  ``type`` or ``action`` arguments.
+
+* Replace string names for ``type`` keyword arguments with the corresponding
+  type objects (e.g. int, float, complex, etc).
+
+* Replace :class:`optparse.Values` with :class:`Namespace` and
+  :exc:`optparse.OptionError` and :exc:`optparse.OptionValueError` with
+  :exc:`ArgumentError`.
+
+* Replace strings with implicit arguments such as ``%default`` or ``%prog`` with
+  the standard python syntax to use dictionaries to format strings, that is,
+  ``%(default)s`` and ``%(prog)s``.
+
+* Replace the OptionParser constructor ``version`` argument with a call to
+  ``parser.add_argument('--version', action='version', version='<the version>')``

+Cmd Example
+-----------
+
+.. sectionauthor:: Raymond Hettinger <python at rcn dot com>
+
+The :mod:`cmd` module is mainly useful for building custom shells that let a
+user work with a program interactively.
+
+This section presents a simple example of how to build a shell around a few of
+the commands in the :mod:`turtle` module.
+
+Basic turtle commands such as :meth:`~turtle.forward` are added to a
+:class:`Cmd` subclass with method named :meth:`do_forward`.  The argument is
+converted to a number and dispatched to the turtle module.  The docstring is
+used in the help utility provided by the shell.
+
+The example also includes a basic record and playback facility implemented with
+the :meth:`~Cmd.precmd` method which is responsible for converting the input to
+lowercase and writing the commands to a file.  The :meth:`do_playback` method
+reads the file and adds the recorded commands to the :attr:`cmdqueue` for
+immediate playback::

+
+**Source code:** :source:`Lib/concurrent/futures/thread.py`
+and :source:`Lib/concurrent/futures/process.py`
+
+.. versionadded:: 3.2
+
+--------------
+
+The :mod:`concurrent.futures` module provides a high-level interface for
+asynchronously executing callables.
+
+The asynchronous execution can be be performed with threads, using
+:class:`ThreadPoolExecutor`, or separate processes, using
+:class:`ProcessPoolExecutor`.  Both implement the same interface, which is
+defined by the abstract :class:`Executor` class.
+
+
+Executor Objects
+----------------
+
+.. class:: Executor
+
+   An abstract class that provides methods to execute calls asynchronously.  It
+   should not be used directly, but through its concrete subclasses.
+
+    .. method:: submit(fn, *args, **kwargs)
+
+       Schedules the callable, *fn*, to be executed as ``fn(*args **kwargs)``
+       and returns a :class:`Future` object representing the execution of the
+       callable. ::
+
+          with ThreadPoolExecutor(max_workers=1) as executor:
+              future = executor.submit(pow, 323, 1235)
+              print(future.result())
+
+    .. method:: map(func, *iterables, timeout=None)
+
+       Equivalent to ``map(func, *iterables)`` except *func* is executed
+       asynchronously and several calls to *func* may be made concurrently.  The
+       returned iterator raises a :exc:`TimeoutError` if :meth:`__next__()` is
+       called and the result isn't available after *timeout* seconds from the
+       original call to :meth:`Executor.map`. *timeout* can be an int or a
+       float.  If *timeout* is not specified or ``None``, there is no limit to
+       the wait time.  If a call raises an exception, then that exception will
+       be raised when its value is retrieved from the iterator.
+
+    .. method:: shutdown(wait=True)
+
+       Signal the executor that it should free any resources that it is using
+       when the currently pending futures are done executing.  Calls to
+       :meth:`Executor.submit` and :meth:`Executor.map` made after shutdown will
+       raise :exc:`RuntimeError`.
+
+       If *wait* is ``True`` then this method will not return until all the
+       pending futures are done executing and the resources associated with the
+       executor have been freed.  If *wait* is ``False`` then this method will
+       return immediately and the resources associated with the executor will be
+       freed when all pending futures are done executing.  Regardless of the
+       value of *wait*, the entire Python program will not exit until all
+       pending futures are done executing.
+
+       You can avoid having to call this method explicitly if you use the
+       :keyword:`with` statement, which will shutdown the :class:`Executor`
+       (waiting as if :meth:`Executor.shutdown` were called with *wait* set to
+       ``True``)::
+
+          import shutil
+          with ThreadPoolExecutor(max_workers=4) as e:
+              e.submit(shutil.copy, 'src1.txt', 'dest1.txt')
+              e.submit(shutil.copy, 'src2.txt', 'dest2.txt')
+              e.submit(shutil.copy, 'src3.txt', 'dest3.txt')
+              e.submit(shutil.copy, 'src3.txt', 'dest4.txt')
+
+
+ThreadPoolExecutor
+------------------
+
+:class:`ThreadPoolExecutor` is a :class:`Executor` subclass that uses a pool of
+threads to execute calls asynchronously.
+
+Deadlocks can occur when the callable associated with a :class:`Future` waits on
+the results of another :class:`Future`.  For example::
+
+   import time
+   def wait_on_b():
+       time.sleep(5)
+       print(b.result()) # b will never complete because it is waiting on a.
+       return 5
+
+   def wait_on_a():
+       time.sleep(5)
+       print(a.result()) # a will never complete because it is waiting on b.
+       return 6
+
+
+   executor = ThreadPoolExecutor(max_workers=2)
+   a = executor.submit(wait_on_b)
+   b = executor.submit(wait_on_a)
+
+And::
+
+   def wait_on_future():
+       f = executor.submit(pow, 5, 2)
+       # This will never complete because there is only one worker thread and
+       # it is executing this function.
+       print(f.result())
+
+   executor = ThreadPoolExecutor(max_workers=1)
+   executor.submit(wait_on_future)
+
+
+.. class:: ThreadPoolExecutor(max_workers)
+

+-------------------
+
+The :class:`ProcessPoolExecutor` class is an :class:`Executor` subclass that

+
+    .. method:: cancel()
+
+       Attempt to cancel the call.  If the call is currently being executed and
+       cannot be cancelled then the method will return ``False``, otherwise the
+       call will be cancelled and the method will return ``True``.
+
+    .. method:: cancelled()
+
+       Return ``True`` if the call was successfully cancelled.
+
+    .. method:: running()
+
+       Return ``True`` if the call is currently being executed and cannot be
+       cancelled.
+
+    .. method:: done()
+
+       Return ``True`` if the call was successfully cancelled or finished
+       running.
+
+    .. method:: result(timeout=None)
+
+       Return the value returned by the call. If the call hasn't yet completed
+       then this method will wait up to *timeout* seconds.  If the call hasn't
+       completed in *timeout* seconds, then a :exc:`TimeoutError` will be
+       raised. *timeout* can be an int or float.  If *timeout* is not specified
+       or ``None``, there is no limit to the wait time.
+
+       If the future is cancelled before completing then :exc:`CancelledError`
+       will be raised.
+
+       If the call raised, this method will raise the same exception.
+
+    .. method:: exception(timeout=None)
+
+       Return the exception raised by the call.  If the call hasn't yet
+       completed then this method will wait up to *timeout* seconds.  If the
+       call hasn't completed in *timeout* seconds, then a :exc:`TimeoutError`
+       will be raised.  *timeout* can be an int or float.  If *timeout* is not
+       specified or ``None``, there is no limit to the wait time.
+
+       If the future is cancelled before completing then :exc:`CancelledError`
+       will be raised.
+
+       If the call completed without raising, ``None`` is returned.
+
+    .. method:: add_done_callback(fn)
+
+       Attaches the callable *fn* to the future.  *fn* will be called, with the
+       future as its only argument, when the future is cancelled or finishes
+       running.
+
+       Added callables are called in the order that they were added and are
+       always called in a thread belonging to the process that added them.  If
+       the callable raises a :exc:`Exception` subclass, it will be logged and
+       ignored.  If the callable raises a :exc:`BaseException` subclass, the
+       behavior is undefined.
+
+       If the future has already completed or been cancelled, *fn* will be
+       called immediately.
+
+   The following :class:`Future` methods are meant for use in unit tests and
+   :class:`Executor` implementations.
+
+    .. method:: set_running_or_notify_cancel()
+
+       This method should only be called by :class:`Executor` implementations
+       before executing the work associated with the :class:`Future` and by unit
+       tests.
+
+       If the method returns ``False`` then the :class:`Future` was cancelled,
+       i.e. :meth:`Future.cancel` was called and returned `True`.  Any threads
+       waiting on the :class:`Future` completing (i.e. through
+       :func:`as_completed` or :func:`wait`) will be woken up.
+
+       If the method returns ``True`` then the :class:`Future` was not cancelled
+       and has been put in the running state, i.e. calls to
+       :meth:`Future.running` will return `True`.

+
+
+Module Functions
+----------------
+
+.. function:: wait(fs, timeout=None, return_when=ALL_COMPLETED)
+
+   Wait for the :class:`Future` instances (possibly created by different
+   :class:`Executor` instances) given by *fs* to complete.  Returns a named
+   2-tuple of sets.  The first set, named ``done``, contains the futures that
+   completed (finished or were cancelled) before the wait completed.  The second
+   set, named ``not_done``, contains uncompleted futures.
+
+   *timeout* can be used to control the maximum number of seconds to wait before
+   returning.  *timeout* can be an int or float.  If *timeout* is not specified
+   or ``None``, there is no limit to the wait time.
+
+   *return_when* indicates when this function should return.  It must be one of
+   the following constants:
+
+   +-----------------------------+----------------------------------------+
+   | Constant                    | Description                            |
+   +=============================+========================================+
+   | :const:`FIRST_COMPLETED`    | The function will return when any      |
+   |                             | future finishes or is cancelled.       |
+   +-----------------------------+----------------------------------------+
+   | :const:`FIRST_EXCEPTION`    | The function will return when any      |
+   |                             | future finishes by raising an          |
+   |                             | exception.  If no future raises an     |
+   |                             | exception then it is equivalent to     |
+   |                             | :const:`ALL_COMPLETED`.                |
+   +-----------------------------+----------------------------------------+
+   | :const:`ALL_COMPLETED`      | The function will return when all      |
+   |                             | futures finish or are cancelled.       |
+   +-----------------------------+----------------------------------------+
+
+.. function:: as_completed(fs, timeout=None)
+
+   Returns an iterator over the :class:`Future` instances (possibly created by
+   different :class:`Executor` instances) given by *fs* that yields futures as
+   they complete (finished or were cancelled).  Any futures that completed
+   before :func:`as_completed` is called will be yielded first.  The returned
+   iterator raises a :exc:`TimeoutError` if :meth:`__next__` is called and the
+   result isn't available after *timeout* seconds from the original call to
+   :func:`as_completed`.  *timeout* can be an int or float.  If *timeout* is not
+   specified or ``None``, there is no limit to the wait time.

+
+
+Quick Start
+-----------
+
+Let's take a very basic configuration file that looks like this:
+
+.. code-block:: ini
+
+   [DEFAULT]
+   ServerAliveInterval = 45
+   Compression = yes
+   CompressionLevel = 9
+   ForwardX11 = yes
+
+   [bitbucket.org]
+   User = hg
+
+   [topsecret.server.com]
+   Port = 50022
+   ForwardX11 = no
+
+The structure of INI files is described `in the following section
+<#supported-ini-file-structure>`_.  Essentially, the file
+consists of sections, each of which contains keys with values.
+:mod:`configparser` classes can read and write such files.  Let's start by
+creating the above configuration file programatically.
+
+.. doctest::
+
+   >>> import configparser
+   >>> config = configparser.ConfigParser()
+   >>> config['DEFAULT'] = {'ServerAliveInterval': '45',
+   ...                      'Compression': 'yes',
+   ...                      'CompressionLevel': '9'}
+   >>> config['bitbucket.org'] = {}
+   >>> config['bitbucket.org']['User'] = 'hg'
+   >>> config['topsecret.server.com'] = {}
+   >>> topsecret = config['topsecret.server.com']
+   >>> topsecret['Port'] = '50022'     # mutates the parser
+   >>> topsecret['ForwardX11'] = 'no'  # same here
+   >>> config['DEFAULT']['ForwardX11'] = 'yes'
+   >>> with open('example.ini', 'w') as configfile:
+   ...   config.write(configfile)
+   ...
+
+As you can see, we can treat a config parser much like a dictionary.
+There are differences, `outlined later <#mapping-protocol-access>`_, but
+the behavior is very close to what you would expect from a dictionary.
+
+Now that we have created and saved a configuration file, let's read it
+back and explore the data it holds.
+
+.. doctest::
+
+   >>> import configparser
+   >>> config = configparser.ConfigParser()
+   >>> config.sections()
+   []
+   >>> config.read('example.ini')
+   ['example.ini']
+   >>> config.sections()
+   ['bitbucket.org', 'topsecret.server.com']
+   >>> 'bitbucket.org' in config
+   True
+   >>> 'bytebong.com' in config
+   False
+   >>> config['bitbucket.org']['User']
+   'hg'
+   >>> config['DEFAULT']['Compression']
+   'yes'
+   >>> topsecret = config['topsecret.server.com']
+   >>> topsecret['ForwardX11']
+   'no'
+   >>> topsecret['Port']
+   '50022'
+   >>> for key in config['bitbucket.org']: print(key)
+   ...
+   user
+   compressionlevel
+   serveraliveinterval
+   compression
+   forwardx11
+   >>> config['bitbucket.org']['ForwardX11']
+   'yes'
+
+As we can see above, the API is pretty straightforward.  The only bit of magic
+involves the ``DEFAULT`` section which provides default values for all other
+sections [1]_.  Note also that keys in sections are
+case-insensitive and stored in lowercase [1]_.
+
+
+Supported Datatypes
+-------------------
+
+Config parsers do not guess datatypes of values in configuration files, always
+storing them internally as strings.  This means that if you need other
+datatypes, you should convert on your own:
+
+.. doctest::
+
+   >>> int(topsecret['Port'])
+   50022
+   >>> float(topsecret['CompressionLevel'])
+   9.0
+
+Extracting Boolean values is not that simple, though.  Passing the value
+to ``bool()`` would do no good since ``bool('False')`` is still
+``True``.  This is why config parsers also provide :meth:`getboolean`.
+This method is case-insensitive and recognizes Boolean values from
+``'yes'``/``'no'``, ``'on'``/``'off'`` and ``'1'``/``'0'`` [1]_.
+For example:
+
+.. doctest::
+
+   >>> topsecret.getboolean('ForwardX11')
+   False
+   >>> config['bitbucket.org'].getboolean('ForwardX11')
+   True
+   >>> config.getboolean('bitbucket.org', 'Compression')
+   True
+
+Apart from :meth:`getboolean`, config parsers also provide equivalent
+:meth:`getint` and :meth:`getfloat` methods, but these are far less
+useful since conversion using :func:`int` and :func:`float` is
+sufficient for these types.
+
+
+Fallback Values
+---------------
+
+As with a dictionary, you can use a section's :meth:`get` method to
+provide fallback values:
+
+.. doctest::
+
+   >>> topsecret.get('Port')
+   '50022'
+   >>> topsecret.get('CompressionLevel')
+   '9'
+   >>> topsecret.get('Cipher')
+   >>> topsecret.get('Cipher', '3des-cbc')
+   '3des-cbc'
+
+Please note that default values have precedence over fallback values.
+For instance, in our example the ``'CompressionLevel'`` key was
+specified only in the ``'DEFAULT'`` section.  If we try to get it from
+the section ``'topsecret.server.com'``, we will always get the default,
+even if we specify a fallback:
+
+.. doctest::
+
+   >>> topsecret.get('CompressionLevel', '3')
+   '9'
+
+One more thing to be aware of is that the parser-level :meth:`get` method
+provides a custom, more complex interface, maintained for backwards
+compatibility.  When using this method, a fallback value can be provided via
+the ``fallback`` keyword-only argument:
+
+.. doctest::
+
+   >>> config.get('bitbucket.org', 'monster',
+   ...            fallback='No such things as monsters')
+   'No such things as monsters'
+
+The same ``fallback`` argument can be used with the :meth:`getint`,
+:meth:`getfloat` and :meth:`getboolean` methods, for example:
+
+.. doctest::
+
+   >>> 'BatchMode' in topsecret
+   False
+   >>> topsecret.getboolean('BatchMode', fallback=True)
+   True
+   >>> config['DEFAULT']['BatchMode'] = 'no'
+   >>> topsecret.getboolean('BatchMode', fallback=True)
+   False
+
+
+Supported INI File Structure
+----------------------------
+
+A configuration file consists of sections, each led by a ``[section]`` header,
+followed by key/value entries separated by a specific string (``=`` or ``:`` by
+default [1]_).  By default, section names are case sensitive but keys are not
+[1]_.  Leading and trailing whitespace is removed from keys and values.
+Values can be omitted, in which case the key/value delimiter may also be left
+out.  Values can also span multiple lines, as long as they are indented deeper
+than the first line of the value.  Depending on the parser's mode, blank lines
+may be treated as parts of multiline values or ignored.
+
+Configuration files may include comments, prefixed by specific
+characters (``#`` and ``;`` by default [1]_).  Comments may appear on
+their own on an otherwise empty line, possibly indented. [1]_
+
+For example:
+
+.. code-block:: ini
+
+   [Simple Values]
+   key=value
+   spaces in keys=allowed
+   spaces in values=allowed as well
+   spaces around the delimiter = obviously
+   you can also use : to delimit keys from values
+
+   [All Values Are Strings]
+   values like this: 1000000
+   or this: 3.14159265359
+   are they treated as numbers? : no
+   integers, floats and booleans are held as: strings
+   can use the API to get converted values directly: true
+
+   [Multiline Values]
+   chorus: I'm a lumberjack, and I'm okay
+       I sleep all night and I work all day
+
+   [No Values]
+   key_without_value
+   empty string value here =

+
+Interpolation of values
+-----------------------
 
-   [My Section]
-   foodir: %(dir)s/whatever
-   dir=frob
-   long: this value continues
-      in the next line
+On top of the core functionality, :class:`ConfigParser` supports
+interpolation.  This means values can be preprocessed before returning them
+from ``get()`` calls.
 
-would resolve the ``%(dir)s`` to the value of ``dir`` (``frob`` in this case).
-All reference expansions are done on demand.
+.. class:: BasicInterpolation()
 
-Default values can be specified by passing them into the :class:`ConfigParser`
-constructor as a dictionary.  Additional defaults  may be passed into the
-:meth:`get` method which will override all others.
+   The default implementation used by :class:`ConfigParser`.  It enables
+   values to contain format strings which refer to other values in the same
+   section, or values in the special default section [1]_.  Additional default
+   values can be provided on initialization.
 
-Sections are normally stored in a built-in dictionary. An alternative dictionary
-type can be passed to the :class:`ConfigParser` constructor. For example, if a
-dictionary type is passed that sorts its keys, the sections will be sorted on
-write-back, as will be the keys within each section.
+   For example:
 
+   .. code-block:: ini
 
-.. class:: RawConfigParser(defaults=None, dict_type=collections.OrderedDict)
+      [Paths]
+      home_dir: /Users
+      my_dir: %(home_dir)s/lumberjack
+      my_pictures: %(my_dir)s/Pictures
 
-   The basic configuration object.  When *defaults* is given, it is initialized
-   into the dictionary of intrinsic defaults.  When *dict_type* is given, it will
-   be used to create the dictionary objects for the list of sections, for the
-   options within a section, and for the default values. This class does not
-   support the magical interpolation behavior.
 
-   .. versionchanged:: 3.1
-      The default *dict_type* is :class:`collections.OrderedDict`.
+   In the example above, :class:`ConfigParser` with *interpolation* set to
+   ``BasicInterpolation()`` would resolve ``%(home_dir)s`` to the value of
+   ``home_dir`` (``/Users`` in this case).  ``%(my_dir)s`` in effect would
+   resolve to ``/Users/lumberjack``.  All interpolations are done on demand so
+   keys used in the chain of references do not have to be specified in any
+   specific order in the configuration file.
 
+   With ``interpolation`` set to ``None``, the parser would simply return
+   ``%(my_dir)s/Pictures`` as the value of ``my_pictures`` and
+   ``%(home_dir)s/lumberjack`` as the value of ``my_dir``.
 
-.. class:: ConfigParser(defaults=None, dict_type=collections.OrderedDict)
+.. class:: ExtendedInterpolation()
 
-   Derived class of :class:`RawConfigParser` that implements the magical
-   interpolation feature and adds optional arguments to the :meth:`get` and
-   :meth:`items` methods.  The values in *defaults* must be appropriate for the
-   ``%()s`` string interpolation.  Note that *__name__* is an intrinsic default;
-   its value is the section name, and will override any value provided in
-   *defaults*.
+   An alternative handler for interpolation which implements a more advanced
+   syntax, used for instance in ``zc.buildout``. Extended interpolation is
+   using ``${section:option}`` to denote a value from a foreign section.
+   Interpolation can span multiple levels. For convenience, if the ``section:``
+   part is omitted, interpolation defaults to the current section (and possibly
+   the default values from the special section).
 
-   All option names used in interpolation will be passed through the
-   :meth:`optionxform` method just like any other option name reference.  For
-   example, using the default implementation of :meth:`optionxform` (which converts
-   option names to lower case), the values ``foo %(bar)s`` and ``foo %(BAR)s`` are
-   equivalent.
+   For example, the configuration specified above with basic interpolation,
+   would look like this with extended interpolation:
 
-   .. versionchanged:: 3.1
-      The default *dict_type* is :class:`collections.OrderedDict`.
+   .. code-block:: ini
 
+      [Paths]

-.. exception:: Error
+Mapping Protocol Access
+-----------------------
 
-   Base class for all other configparser exceptions.
+.. versionadded:: 3.2
+
+Mapping protocol access is a generic name for functionality that enables using
+custom objects as if they were dictionaries.  In case of :mod:`configparser`,
+the mapping interface implementation is using the
+``parser['section']['option']`` notation.
+
+``parser['section']`` in particular returns a proxy for the section's data in
+the parser.  This means that the values are not copied but they are taken from
+the original parser on demand.  What's even more important is that when values
+are changed on a section proxy, they are actually mutated in the original
+parser.
+
+:mod:`configparser` objects behave as close to actual dictionaries as possible.
+The mapping interface is complete and adheres to the ``MutableMapping`` ABC.
+However, there are a few differences that should be taken into account:
+
+* By default, all keys in sections are accessible in a case-insensitive manner
+  [1]_.  E.g. ``for option in parser["section"]`` yields only ``optionxform``'ed
+  option key names.  This means lowercased keys by default.  At the same time,
+  for a section that holds the key ``'a'``, both expressions return ``True``::
+
+     "a" in parser["section"]
+     "A" in parser["section"]
+
+* All sections include ``DEFAULTSECT`` values as well which means that
+  ``.clear()`` on a section may not leave the section visibly empty.  This is
+  because default values cannot be deleted from the section (because technically
+  they are not there).  If they are overriden in the section, deleting causes
+  the default value to be visible again.  Trying to delete a default value
+  causes a ``KeyError``.
+
+* Trying to delete the ``DEFAULTSECT`` raises ``ValueError``.
+
+* ``parser.get(section, option, **kwargs)`` - the second argument is **not**
+  a fallback value. Note however that the section-level ``get()`` methods are
+  compatible both with the mapping protocol and the classic configparser API.
+
+* ``parser.items()`` is compatible with the mapping protocol (returns a list of
+  *section_name*, *section_proxy* pairs including the DEFAULTSECT).  However,
+  this method can also be invoked with arguments: ``parser.items(section, raw,
+  vars)``. The latter call returns a list of *option*, *value* pairs for
+  a specified ``section``, with all interpolations expanded (unless
+  ``raw=True`` is provided).
+
+The mapping protocol is implemented on top of the existing legacy API so that
+subclasses overriding the original interface still should have mappings working
+as expected.
+
+
+Customizing Parser Behaviour
+----------------------------
+
+There are nearly as many INI format variants as there are applications using it.
+:mod:`configparser` goes a long way to provide support for the largest sensible
+set of INI styles available.  The default functionality is mainly dictated by
+historical background and it's very likely that you will want to customize some
+of the features.
+
+The most common way to change the way a specific config parser works is to use
+the :meth:`__init__` options:
+
+* *defaults*, default value: ``None``
+
+  This option accepts a dictionary of key-value pairs which will be initially
+  put in the ``DEFAULT`` section.  This makes for an elegant way to support
+  concise configuration files that don't specify values which are the same as
+  the documented default.
+
+  Hint: if you want to specify default values for a specific section, use
+  :meth:`read_dict` before you read the actual file.
+
+* *dict_type*, default value: :class:`collections.OrderedDict`
+
+  This option has a major impact on how the mapping protocol will behave and how
+  the written configuration files look.  With the default ordered
+  dictionary, every section is stored in the order they were added to the
+  parser.  Same goes for options within sections.
+
+  An alternative dictionary type can be used for example to sort sections and
+  options on write-back.  You can also use a regular dictionary for performance
+  reasons.
+
+  Please note: there are ways to add a set of key-value pairs in a single
+  operation.  When you use a regular dictionary in those operations, the order
+  of the keys may be random.  For example:
+
+  .. doctest::
+
+     >>> parser = configparser.ConfigParser()
+     >>> parser.read_dict({'section1': {'key1': 'value1',
+     ...                                'key2': 'value2',
+     ...                                'key3': 'value3'},
+     ...                   'section2': {'keyA': 'valueA',
+     ...                                'keyB': 'valueB',
+     ...                                'keyC': 'valueC'},
+     ...                   'section3': {'foo': 'x',
+     ...                                'bar': 'y',
+     ...                                'baz': 'z'}
+     ... })
+     >>> parser.sections()
+     ['section3', 'section2', 'section1']
+     >>> [option for option in parser['section3']]
+     ['baz', 'foo', 'bar']
+
+  In these operations you need to use an ordered dictionary as well:
+
+  .. doctest::
+
+     >>> from collections import OrderedDict
+     >>> parser = configparser.ConfigParser()
+     >>> parser.read_dict(
+     ...   OrderedDict((
+     ...     ('s1',
+     ...      OrderedDict((
+     ...        ('1', '2'),
+     ...        ('3', '4'),
+     ...        ('5', '6'),
+     ...      ))
+     ...     ),
+     ...     ('s2',
+     ...      OrderedDict((
+     ...        ('a', 'b'),
+     ...        ('c', 'd'),
+     ...        ('e', 'f'),
+     ...      ))
+     ...     ),
+     ...   ))
+     ... )
+     >>> parser.sections()
+     ['s1', 's2']
+     >>> [option for option in parser['s1']]
+     ['1', '3', '5']
+     >>> [option for option in parser['s2'].values()]
+     ['b', 'd', 'f']
+
+* *allow_no_value*, default value: ``False``
+
+  Some configuration files are known to include settings without values, but
+  which otherwise conform to the syntax supported by :mod:`configparser`.  The
+  *allow_no_value* parameter to the constructor can be used to
+  indicate that such values should be accepted:
+
+  .. doctest::
+
+     >>> import configparser
+
+     >>> sample_config = """
+     ... [mysqld]
+     ...   user = mysql
+     ...   pid-file = /var/run/mysqld/mysqld.pid
+     ...   skip-external-locking
+     ...   old_passwords = 1
+     ...   skip-bdb
+     ...   # we don't need ACID today
+     ...   skip-innodb
+     ... """
+     >>> config = configparser.ConfigParser(allow_no_value=True)
+     >>> config.read_string(sample_config)
+
+     >>> # Settings with values are treated as before:
+     >>> config["mysqld"]["user"]
+     'mysql'
+
+     >>> # Settings without values provide None:
+     >>> config["mysqld"]["skip-bdb"]
+
+     >>> # Settings which aren't specified still raise an error:
+     >>> config["mysqld"]["does-not-exist"]
+     Traceback (most recent call last):
+       ...
+     KeyError: 'does-not-exist'
+
+* *delimiters*, default value: ``('=', ':')``
+
+  Delimiters are substrings that delimit keys from values within a section. The
+  first occurence of a delimiting substring on a line is considered a delimiter.
+  This means values (but not keys) can contain the delimiters.
+
+  See also the *space_around_delimiters* argument to
+  :meth:`ConfigParser.write`.
+
+* *comment_prefixes*, default value: ``('#', ';')``
+
+* *inline_comment_prefixes*, default value: ``None``
+
+  Comment prefixes are strings that indicate the start of a valid comment within
+  a config file. *comment_prefixes* are used only on otherwise empty lines
+  (optionally indented) whereas *inline_comment_prefixes* can be used after
+  every valid value (e.g.  section names, options and empty lines as well). By
+  default inline comments are disabled and ``'#'`` and ``';'`` are used as
+  prefixes for whole line comments.
+
+  .. versionchanged:: 3.2
+     In previous versions of :mod:`configparser` behaviour matched
+     ``comment_prefixes=('#',';')`` and ``inline_comment_prefixes=(';',)``.
+
+  Please note that config parsers don't support escaping of comment prefixes so
+  using *inline_comment_prefixes* may prevent users from specifying option
+  values with characters used as comment prefixes. When in doubt, avoid setting
+  *inline_comment_prefixes*. In any circumstances, the only way of storing
+  comment prefix characters at the beginning of a line in multiline values is to
+  interpolate the prefix, for example::
+
+    >>> from configparser import ConfigParser, ExtendedInterpolation
+    >>> parser = ConfigParser(interpolation=ExtendedInterpolation())
+    >>> # the default BasicInterpolation could be used as well
+    >>> parser.read_string("""
+    ... [DEFAULT]
+    ... hash = #
+    ...
+    ... [hashes]
+    ... shebang =
+    ...   ${hash}!/usr/bin/env python
+    ...   ${hash} -*- coding: utf-8 -*-
+    ...
+    ... extensions =
+    ...   enabled_extension
+    ...   another_extension
+    ...   #disabled_by_comment
+    ...   yet_another_extension
+    ...
+    ... interpolation not necessary = if # is not at line start
+    ... even in multiline values = line #1
+    ...   line #2
+    ...   line #3
+    ... """)
+    >>> print(parser['hashes']['shebang'])
+
+    #!/usr/bin/env python
+    # -*- coding: utf-8 -*-
+    >>> print(parser['hashes']['extensions'])
+
+    enabled_extension
+    another_extension
+    yet_another_extension
+    >>> print(parser['hashes']['interpolation not necessary'])
+    if # is not at line start
+    >>> print(parser['hashes']['even in multiline values'])
+    line #1
+    line #2
+    line #3
+
+* *strict*, default value: ``True``
+
+  When set to ``True``, the parser will not allow for any section or option
+  duplicates while reading from a single source (using :meth:`read_file`,
+  :meth:`read_string` or :meth:`read_dict`). It is recommended to use strict
+  parsers in new applications.
+
+  .. versionchanged:: 3.2
+     In previous versions of :mod:`configparser` behaviour matched
+     ``strict=False``.
+
+* *empty_lines_in_values*, default value: ``True``
+
+  In config parsers, values can span multiple lines as long as they are
+  indented more than the key that holds them.  By default parsers also let
+  empty lines to be parts of values.  At the same time, keys can be arbitrarily
+  indented themselves to improve readability.  In consequence, when
+  configuration files get big and complex, it is easy for the user to lose
+  track of the file structure.  Take for instance:
+
+  .. code-block:: ini
+
+     [Section]
+     key = multiline
+       value with a gotcha
+
+      this = is still a part of the multiline value of 'key'
+
+  This can be especially problematic for the user to see if she's using a
+  proportional font to edit the file.  That is why when your application does
+  not need values with empty lines, you should consider disallowing them.  This
+  will make empty lines split keys every time.  In the example above, it would
+  produce two keys, ``key`` and ``this``.
+
+* *default_section*, default value: ``configparser.DEFAULTSECT`` (that is:
+  ``"DEFAULT"``)
+
+  The convention of allowing a special section of default values for other
+  sections or interpolation purposes is a powerful concept of this library,
+  letting users create complex declarative configurations. This section is
+  normally called ``"DEFAULT"`` but this can be customized to point to any
+  other valid section name. Some typical values include: ``"general"`` or
+  ``"common"``. The name provided is used for recognizing default sections when
+  reading from any source and is used when writing configuration back to
+  a file. Its current value can be retrieved using the
+  ``parser_instance.default_section`` attribute and may be modified at runtime
+  (i.e. to convert files from one format to another).
+
+* *interpolation*, default value: ``configparser.BasicInterpolation``
+
+  Interpolation behaviour may be customized by providing a custom handler
+  through the *interpolation* argument. ``None`` can be used to turn off
+  interpolation completely, ``ExtendedInterpolation()`` provides a more
+  advanced variant inspired by ``zc.buildout``. More on the subject in the
+  `dedicated documentation section <#interpolation-of-values>`_.
+  :class:`RawConfigParser` has a default value of ``None``.
+
+
+More advanced customization may be achieved by overriding default values of
+these parser attributes.  The defaults are defined on the classes, so they
+may be overriden by subclasses or by attribute assignment.
+
+.. attribute:: BOOLEAN_STATES
+
+  By default when using :meth:`getboolean`, config parsers consider the
+  following values ``True``: ``'1'``, ``'yes'``, ``'true'``, ``'on'`` and the
+  following values ``False``: ``'0'``, ``'no'``, ``'false'``, ``'off'``.  You
+  can override this by specifying a custom dictionary of strings and their
+  Boolean outcomes. For example:
+
+  .. doctest::
+
+     >>> custom = configparser.ConfigParser()
+     >>> custom['section1'] = {'funky': 'nope'}
+     >>> custom['section1'].getboolean('funky')
+     Traceback (most recent call last):
+     ...
+     ValueError: Not a boolean: nope
+     >>> custom.BOOLEAN_STATES = {'sure': True, 'nope': False}
+     >>> custom['section1'].getboolean('funky')
+     False
+
+  Other typical Boolean pairs include ``accept``/``reject`` or
+  ``enabled``/``disabled``.
+
+.. method:: optionxform(option)
+
+  This method transforms option names on every read, get, or set
+  operation.  The default converts the name to lowercase.  This also
+  means that when a configuration file gets written, all keys will be
+  lowercase.  Override this method if that's unsuitable.
+  For example:
+
+  .. doctest::
+
+     >>> config = """
+     ... [Section1]
+     ... Key = Value
+     ...
+     ... [Section2]
+     ... AnotherKey = Value
+     ... """
+     >>> typical = configparser.ConfigParser()
+     >>> typical.read_string(config)
+     >>> list(typical['Section1'].keys())
+     ['key']
+     >>> list(typical['Section2'].keys())
+     ['anotherkey']
+     >>> custom = configparser.RawConfigParser()
+     >>> custom.optionxform = lambda option: option
+     >>> custom.read_string(config)
+     >>> list(custom['Section1'].keys())
+     ['Key']
+     >>> list(custom['Section2'].keys())
+     ['AnotherKey']
+
+.. attribute:: SECTCRE
+
+  A compiled regular expression used to parse section headers. The default
+  matches ``[section]`` to the name ``"section"``. Whitespace is considered part
+  of the section name, thus ``[  larch  ]`` will be read as a section of name
+  ``"  larch  "``. Override this attribute if that's unsuitable.  For example:
+
+  .. doctest::
+
+     >>> config = """
+     ... [Section 1]
+     ... option = value
+     ...
+     ... [  Section 2  ]
+     ... another = val
+     ... """
+     >>> typical = ConfigParser()
+     >>> typical.read_string(config)
+     >>> typical.sections()
+     ['Section 1', '  Section 2  ']
+     >>> custom = ConfigParser()
+     >>> custom.SECTCRE = re.compile(r"\[ *(?P<header>[^]]+?) *\]")
+     >>> custom.read_string(config)
+     >>> custom.sections()
+     ['Section 1', 'Section 2']
+
+  .. note::
+
+     While ConfigParser objects also use an ``OPTCRE`` attribute for recognizing
+     option lines, it's not recommended to override it because that would
+     interfere with constructor options *allow_no_value* and *delimiters*.
+
+
+Legacy API Examples
+-------------------
+
+Mainly because of backwards compatibility concerns, :mod:`configparser`
+provides also a legacy API with explicit ``get``/``set`` methods.  While there
+are valid use cases for the methods outlined below, mapping protocol access is
+preferred for new projects.  The legacy API is at times more advanced,
+low-level and downright counterintuitive.
 
+An example of writing to a configuration file::
 
-.. exception:: NoSectionError
+   import configparser
 
-   Exception raised when a specified section is not found.
+   config = configparser.RawConfigParser()
 
+   # Please note that using RawConfigParser's set functions, you can assign
+   # non-string values to keys internally, but will receive an error when
+   # attempting to write to a file or when you get it in non-raw mode. Setting
+   # values using the mapping protocol or ConfigParser's set() does not allow
+   # such assignments to take place.
+   config.add_section('Section1')
+   config.set('Section1', 'int', '15')
+   config.set('Section1', 'bool', 'true')
+   config.set('Section1', 'float', '3.1415')
+   config.set('Section1', 'baz', 'fun')
+   config.set('Section1', 'bar', 'Python')
+   config.set('Section1', 'foo', '%(bar)s is %(baz)s!')
 
-.. exception:: DuplicateSectionError
+   # Writing our configuration file to 'example.cfg'
+   with open('example.cfg', 'w') as configfile:
+       config.write(configfile)
 
-   Exception raised if :meth:`add_section` is called with the name of a section
-   that is already present.
+An example of reading the configuration file again::
 
+   import configparser
 
-.. exception:: NoOptionError
+   config = configparser.RawConfigParser()
+   config.read('example.cfg')
 
-   Exception raised when a specified option is not found in the specified  section.
+   # getfloat() raises an exception if the value is not a float
+   # getint() and getboolean() also do this for their respective types
+   float = config.getfloat('Section1', 'float')
+   int = config.getint('Section1', 'int')
+   print(float + int)
 
+   # Notice that the next output does not interpolate '%(bar)s' or '%(baz)s'.
+   # This is because we are using a RawConfigParser().
+   if config.getboolean('Section1', 'bool'):
+       print(config.get('Section1', 'foo'))
 
-.. exception:: InterpolationError
+To get interpolation, use :class:`ConfigParser`::
 
-   Base class for exceptions raised when problems occur performing string
-   interpolation.
+   import configparser
 
+   cfg = configparser.ConfigParser()
+   cfg.read('example.cfg')
 
-.. exception:: InterpolationDepthError
+   # Set the optional `raw` argument of get() to True if you wish to disable
+   # interpolation in a single get operation.
+   print(cfg.get('Section1', 'foo', raw=False)) # -> "Python is fun!"
+   print(cfg.get('Section1', 'foo', raw=True))  # -> "%(bar)s is %(baz)s!"
 
-   Exception raised when string interpolation cannot be completed because the
-   number of iterations exceeds :const:`MAX_INTERPOLATION_DEPTH`. Subclass of
-   :exc:`InterpolationError`.
+   # The optional `vars` argument is a dict with members that will take
+   # precedence in interpolation.
+   print(cfg.get('Section1', 'foo', vars={'bar': 'Documentation',
+                                             'baz': 'evil'}))
 
+   # The optional `fallback` argument can be used to provide a fallback value
+   print(cfg.get('Section1', 'foo'))
+         # -> "Python is fun!"
 
-.. exception:: InterpolationMissingOptionError
+   print(cfg.get('Section1', 'foo', fallback='Monty is not.'))
+         # -> "Python is fun!"
 
-   Exception raised when an option referenced from a value does not exist. Subclass
-   of :exc:`InterpolationError`.
+   print(cfg.get('Section1', 'monster', fallback='No such things as monsters.'))
+         # -> "No such things as monsters."
 
+   # A bare print(cfg.get('Section1', 'monster')) would raise NoOptionError
+   # but we can also use:
 
-.. exception:: InterpolationSyntaxError
+   print(cfg.get('Section1', 'monster', fallback=None))
+         # -> None
 
-   Exception raised when the source text into which substitutions are made does not
-   conform to the required syntax. Subclass of :exc:`InterpolationError`.
+Default values are available in both types of ConfigParsers.  They are used in
+interpolation if an option used is not defined elsewhere. ::
 
+   import configparser
 
-.. exception:: MissingSectionHeaderError
+   # New instance with 'bar' and 'baz' defaulting to 'Life' and 'hard' each

+ConfigParser Objects
+--------------------
 
+.. class:: ConfigParser(defaults=None, dict_type=collections.OrderedDict, allow_no_value=False, delimiters=('=', ':'), comment_prefixes=('#', ';'), inline_comment_prefixes=None, strict=True, empty_lines_in_values=True, default_section=configparser.DEFAULTSECT, interpolation=BasicInterpolation())
+
+   The main configuration parser.  When *defaults* is given, it is initialized
+   into the dictionary of intrinsic defaults.  When *dict_type* is given, it
+   will be used to create the dictionary objects for the list of sections, for
+   the options within a section, and for the default values.
+
+   When *delimiters* is given, it is used as the set of substrings that
+   divide keys from values.  When *comment_prefixes* is given, it will be used
+   as the set of substrings that prefix comments in otherwise empty lines.
+   Comments can be indented. When *inline_comment_prefixes* is given, it will be
+   used as the set of substrings that prefix comments in non-empty lines.
+
+   line and inline comments.  For backwards compatibility, the default value for
+   *comment_prefixes* is a special value that indicates that ``;`` and ``#`` can
+   start whole line comments while only ``;`` can start inline comments.
+
+   When *strict* is ``True`` (the default), the parser won't allow for
+   any section or option duplicates while reading from a single source (file,
+   string or dictionary), raising :exc:`DuplicateSectionError` or
+   :exc:`DuplicateOptionError`.  When *empty_lines_in_values* is ``False``
+   (default: ``True``), each empty line marks the end of an option.  Otherwise,
+   internal empty lines of a multiline option are kept as part of the value.
+   When *allow_no_value* is ``True`` (default: ``False``), options without
+   values are accepted; the value held for these is ``None`` and they are
+   serialized without the trailing delimiter.
+
+   When *default_section* is given, it specifies the name for the special
+   section holding default values for other sections and interpolation purposes
+   (normally named ``"DEFAULT"``). This value can be retrieved and changed on
+   runtime using the ``default_section`` instance attribute.
+
+   Interpolation behaviour may be customized by providing a custom handler
+   through the *interpolation* argument. ``None`` can be used to turn off
+   interpolation completely, ``ExtendedInterpolation()`` provides a more
+   advanced variant inspired by ``zc.buildout``. More on the subject in the
+   `dedicated documentation section <#interpolation-of-values>`_.
 
-.. data:: MAX_INTERPOLATION_DEPTH
+   All option names used in interpolation will be passed through the
+   :meth:`optionxform` method just like any other option name reference.  For
+   example, using the default implementation of :meth:`optionxform` (which
+   converts option names to lower case), the values ``foo %(bar)s`` and ``foo
+   %(BAR)s`` are equivalent.

-RawConfigParser Objects
------------------------
+   .. method:: sections()
 
-:class:`RawConfigParser` instances have the following methods:
+      Return a list of the sections available; the *default section* is not
+      included in the list.
 
 
-.. method:: RawConfigParser.defaults()
+   .. method:: add_section(section)
 
-   Return a dictionary containing the instance-wide defaults.
+      Add a section named *section* to the instance.  If a section by the given
+      name already exists, :exc:`DuplicateSectionError` is raised.  If the
+      *default section* name is passed, :exc:`ValueError` is raised.  The name
+      of the section must be a string; if not, :exc:`TypeError` is raised.
 
+      .. versionchanged:: 3.2
+         Non-string section names raise :exc:`TypeError`.
 
-.. method:: RawConfigParser.sections()
 
-   Return a list of the sections available; ``DEFAULT`` is not included in the
-   list.
+   .. method:: has_section(section)
 
+      Indicates whether the named *section* is present in the configuration.
+      The *default section* is not acknowledged.
 
-.. method:: RawConfigParser.add_section(section)
 
-   Add a section named *section* to the instance.  If a section by the given name
-   already exists, :exc:`DuplicateSectionError` is raised. If the name
-   ``DEFAULT`` (or any of it's case-insensitive variants) is passed,
-   :exc:`ValueError` is raised.
+   .. method:: options(section)
 
-.. method:: RawConfigParser.has_section(section)
+      Return a list of options available in the specified *section*.
 
-   Indicates whether the named section is present in the configuration. The

-.. method:: RawConfigParser.options(section)
+      If the given *section* exists, and contains the given *option*, return
+      :const:`True`; otherwise return :const:`False`. If the specified

-   Returns a list of options available in the specified *section*.
 
+   .. method:: read(filenames, encoding=None)
 
-.. method:: RawConfigParser.has_option(section, option)
+      Attempt to read and parse a list of filenames, returning a list of
+      filenames which were successfully parsed.  If *filenames* is a string, it
+      is treated as a single filename.  If a file named in *filenames* cannot
+      be opened, that file will be ignored.  This is designed so that you can
+      specify a list of potential configuration file locations (for example,
+      the current directory, the user's home directory, and some system-wide
+      directory), and all existing configuration files in the list will be
+      read.  If none of the named files exist, the :class:`ConfigParser`
+      instance will contain an empty dataset.  An application which requires
+      initial values to be loaded from a file should load the required file or
+      files using :meth:`read_file` before calling :meth:`read` for any
+      optional files::
 
-   If the given section exists, and contains the given option, return
-   :const:`True`; otherwise return :const:`False`.

-   The default implementation returns a lower-case version of *option*;
-   subclasses may override this or client code can set an attribute of this name
-   on instances to affect this behavior.
+      If the given section exists, set the given option to the specified value;
+      otherwise raise :exc:`NoSectionError`.  *option* and *value* must be

-   You don't necessarily need to subclass a ConfigParser to use this method, you
-   can also re-set it on an instance, to a function that takes a string

-      ...
-      cfgparser.optionxform = str
+   .. method:: write(fileobject, space_around_delimiters=True)

+   contextmanager uses :class:`ContextDecorator` so the context managers it
+   creates can be used as decorators as well as in :keyword:`with` statements.
 
-.. function:: nested(mgr1[, mgr2[, ...]])
-
-   Combine multiple context managers into a single nested context manager.
-
-   This function has been deprecated in favour of the multiple manager form
-   of the :keyword:`with` statement.
-
-   The one advantage of this function over the multiple manager form of the
-   :keyword:`with` statement is that argument unpacking allows it to be
-   used with a variable number of context managers as follows::
-
-      from contextlib import nested
-
-      with nested(*managers):
-          do_something()
-
-   Note that if the :meth:`__exit__` method of one of the nested context managers
-   indicates an exception should be suppressed, no exception information will be
-   passed to any remaining outer context managers. Similarly, if the
-   :meth:`__exit__` method of one of the nested managers raises an exception, any
-   previous exception state will be lost; the new exception will be passed to the
-   :meth:`__exit__` methods of any remaining outer context managers. In general,
-   :meth:`__exit__` methods should avoid raising exceptions, and in particular they
-   should not re-raise a passed-in exception.
-
-   This function has two major quirks that have led to it being deprecated. Firstly,
-   as the context managers are all constructed before the function is invoked, the
-   :meth:`__new__` and :meth:`__init__` methods of the inner context managers are
-   not actually covered by the scope of the outer context managers. That means, for
-   example, that using :func:`nested` to open two files is a programming error as the
-   first file will not be closed promptly if an exception is thrown when opening
-   the second file.
-
-   Secondly, if the :meth:`__enter__` method of one of the inner context managers
-   raises an exception that is caught and suppressed by the :meth:`__exit__` method
-   of one of the outer context managers, this construct will raise
-   :exc:`RuntimeError` rather than skipping the body of the :keyword:`with`
-   statement.
-
-   Developers that need to support nesting of a variable number of context managers
-   can either use the :mod:`warnings` module to suppress the DeprecationWarning
-   raised by this function or else use this function as a model for an application
-   specific implementation.

+
+   A base class that enables a context manager to also be used as a decorator.

 The :mod:`functools` module defines the following functions:
 
+.. function:: cmp_to_key(func)
+
+   Transform an old-style comparison function to a key-function.  Used with
+   tools that accept key functions (such as :func:`sorted`, :func:`min`,
+   :func:`max`, :func:`heapq.nlargest`, :func:`heapq.nsmallest`,
+   :func:`itertools.groupby`).  This function is primarily used as a transition
+   tool for programs being converted from Py2.x which supported the use of
+   comparison functions.
+
+   A compare function is any callable that accept two arguments, compares them,
+   and returns a negative number for less-than, zero for equality, or a positive
+   number for greater-than.  A key function is a callable that accepts one
+   argument and returns another value indicating the position in the desired
+   collation sequence.
+
+   Example::
+
+       sorted(iterable, key=cmp_to_key(locale.strcoll))  # locale-aware sort order
+
+   .. versionadded:: 3.2
+
+
+.. decorator:: lru_cache(maxsize=100)
+
+   Decorator to wrap a function with a memoizing callable that saves up to the
+   *maxsize* most recent calls.  It can save time when an expensive or I/O bound
+   function is periodically called with the same arguments.
+
+   Since a dictionary is used to cache results, the positional and keyword
+   arguments to the function must be hashable.
+
+   If *maxsize* is set to None, the LRU feature is disabled and the cache
+   can grow without bound.
+
+   To help measure the effectiveness of the cache and tune the *maxsize*
+   parameter, the wrapped function is instrumented with a :func:`cache_info`
+   function that returns a :term:`named tuple` showing *hits*, *misses*,
+   *maxsize* and *currsize*.  In a multi-threaded environment, the hits
+   and misses are approximate.
+
+   The decorator also provides a :func:`cache_clear` function for clearing or
+   invalidating the cache.
+
+   The original underlying function is accessible through the
+   :attr:`__wrapped__` attribute.  This is useful for introspection, for
+   bypassing the cache, or for rewrapping the function with a different cache.
+
+   An `LRU (least recently used) cache
+   <http://en.wikipedia.org/wiki/Cache_algorithms#Least_Recently_Used>`_ works
+   best when more recent calls are the best predictors of upcoming calls (for
+   example, the most popular articles on a news server tend to change daily).
+   The cache's size limit assures that the cache does not grow without bound on
+   long-running processes such as web servers.
+
+   Example of an LRU cache for static web content::
+
+        @lru_cache(maxsize=20)
+        def get_pep(num):
+            'Retrieve text of a Python Enhancement Proposal'

+Fetching attributes statically
+------------------------------
+
+Both :func:`getattr` and :func:`hasattr` can trigger code execution when
+fetching or checking for the existence of attributes. Descriptors, like
+properties, will be invoked and :meth:`__getattr__` and :meth:`__getattribute__`
+may be called.
+
+For cases where you want passive introspection, like documentation tools, this
+can be inconvenient. `getattr_static` has the same signature as :func:`getattr`
+but avoids executing code when it fetches attributes.
+
+.. function:: getattr_static(obj, attr, default=None)
+
+   Retrieve attributes without triggering dynamic lookup via the
+   descriptor protocol, `__getattr__` or `__getattribute__`.
+
+   Note: this function may not be able to retrieve all attributes
+   that getattr can fetch (like dynamically created attributes)
+   and may find attributes that getattr can't (like descriptors
+   that raise AttributeError). It can also return descriptors objects
+   instead of instance members.
+
+   If the instance `__dict__` is shadowed by another member (for example a
+   property) then this function will be unable to find instance members.
+
+   .. versionadded:: 3.2
+
+`getattr_static` does not resolve descriptors, for example slot descriptors or
+getset descriptors on objects implemented in C. The descriptor object
+is returned instead of the underlying attribute.
+
+You can handle these with code like the following. Note that
+for arbitrary getset descriptors invoking these may trigger
+code execution::
+
+   # example code for resolving the builtin descriptor types
+   class _foo:
+       __slots__ = ['foo']
+
+   slot_descriptor = type(_foo.foo)
+   getset_descriptor = type(type(open(__file__)).name)
+   wrapper_descriptor = type(str.__dict__['__add__'])
+   descriptor_types = (slot_descriptor, getset_descriptor, wrapper_descriptor)
+
+   result = getattr_static(some_object, 'foo')
+   if type(result) in descriptor_types:
+       try:
+           result = result.__get__()
+       except AttributeError:
+           # descriptors can raise AttributeError to
+           # indicate there is no underlying value

+   each level.
 
    If *separators* is an ``(item_separator, dict_separator)`` tuple, then it
    will be used instead of the default ``(', ', ': ')`` separators.  ``(',',

+
+This section describes the API for configuring the logging module.
+
+.. _logging-config-api:
+
+Configuration functions
+^^^^^^^^^^^^^^^^^^^^^^^
+
+The following functions configure the logging module. They are located in the
+:mod:`logging.config` module.  Their use is optional --- you can configure the
+logging module using these functions or by making calls to the main API (defined
+in :mod:`logging` itself) and defining handlers which are declared either in
+:mod:`logging` or :mod:`logging.handlers`.
+
+.. function:: dictConfig(config)
+
+    Takes the logging configuration from a dictionary.  The contents of
+    this dictionary are described in :ref:`logging-config-dictschema`
+    below.
+
+    If an error is encountered during configuration, this function will
+    raise a :exc:`ValueError`, :exc:`TypeError`, :exc:`AttributeError`
+    or :exc:`ImportError` with a suitably descriptive message.  The
+    following is a (possibly incomplete) list of conditions which will
+    raise an error:
+
+    * A ``level`` which is not a string or which is a string not
+      corresponding to an actual logging level.
+    * A ``propagate`` value which is not a boolean.
+    * An id which does not have a corresponding destination.
+    * A non-existent handler id found during an incremental call.
+    * An invalid logger name.
+    * Inability to resolve to an internal or external object.
+
+    Parsing is performed by the :class:`DictConfigurator` class, whose
+    constructor is passed the dictionary used for configuration, and
+    has a :meth:`configure` method.  The :mod:`logging.config` module
+    has a callable attribute :attr:`dictConfigClass`
+    which is initially set to :class:`DictConfigurator`.
+    You can replace the value of :attr:`dictConfigClass` with a
+    suitable implementation of your own.
+
+    :func:`dictConfig` calls :attr:`dictConfigClass` passing
+    the specified dictionary, and then calls the :meth:`configure` method on
+    the returned object to put the configuration into effect::
+
+          def dictConfig(config):
+              dictConfigClass(config).configure()
+
+    For example, a subclass of :class:`DictConfigurator` could call
+    ``DictConfigurator.__init__()`` in its own :meth:`__init__()`, then
+    set up custom prefixes which would be usable in the subsequent
+    :meth:`configure` call. :attr:`dictConfigClass` would be bound to
+    this new subclass, and then :func:`dictConfig` could be called exactly as
+    in the default, uncustomized state.
+
+   .. versionadded:: 3.2
+
+.. function:: fileConfig(fname[, defaults])
+
+   Reads the logging configuration from a :mod:`configparser`\-format file named
+   *fname*. This function can be called several times from an application,
+   allowing an end user to select from various pre-canned
+   configurations (if the developer provides a mechanism to present the choices
+   and load the chosen configuration). Defaults to be passed to the ConfigParser
+   can be specified in the *defaults* argument.
+
+
+.. function:: listen(port=DEFAULT_LOGGING_CONFIG_PORT)
+
+   Starts up a socket server on the specified port, and listens for new
+   configurations. If no port is specified, the module's default
+   :const:`DEFAULT_LOGGING_CONFIG_PORT` is used. Logging configurations will be
+   sent as a file suitable for processing by :func:`fileConfig`. Returns a
+   :class:`Thread` instance on which you can call :meth:`start` to start the
+   server, and which you can :meth:`join` when appropriate. To stop the server,
+   call :func:`stopListening`.
+
+   To send a configuration to the socket, read in the configuration file and
+   send it to the socket as a string of bytes preceded by a four-byte length
+   string packed in binary using ``struct.pack('>L', n)``.
+
+
+.. function:: stopListening()
+
+   Stops the listening server which was created with a call to :func:`listen`.
+   This is typically called before calling :meth:`join` on the return value from
+   :func:`listen`.
+
+
+.. _logging-config-dictschema:
+
+Configuration dictionary schema
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Describing a logging configuration requires listing the various
+objects to create and the connections between them; for example, you
+may create a handler named 'console' and then say that the logger
+named 'startup' will send its messages to the 'console' handler.
+These objects aren't limited to those provided by the :mod:`logging`
+module because you might write your own formatter or handler class.
+The parameters to these classes may also need to include external
+objects such as ``sys.stderr``.  The syntax for describing these
+objects and connections is defined in :ref:`logging-config-dict-connections`
+below.
+
+Dictionary Schema Details
+"""""""""""""""""""""""""
+
+The dictionary passed to :func:`dictConfig` must contain the following
+keys:
+
+* *version* - to be set to an integer value representing the schema
+  version.  The only valid value at present is 1, but having this key
+  allows the schema to evolve while still preserving backwards
+  compatibility.
+
+All other keys are optional, but if present they will be interpreted
+as described below.  In all cases below where a 'configuring dict' is
+mentioned, it will be checked for the special ``'()'`` key to see if a
+custom instantiation is required.  If so, the mechanism described in
+:ref:`logging-config-dict-userdef` below is used to create an instance;
+otherwise, the context is used to determine what to instantiate.
+
+* *formatters* - the corresponding value will be a dict in which each
+  key is a formatter id and each value is a dict describing how to
+  configure the corresponding Formatter instance.
+
+  The configuring dict is searched for keys ``format`` and ``datefmt``
+  (with defaults of ``None``) and these are used to construct a
+  :class:`logging.Formatter` instance.
+
+* *filters* - the corresponding value will be a dict in which each key
+  is a filter id and each value is a dict describing how to configure
+  the corresponding Filter instance.
+
+  The configuring dict is searched for the key ``name`` (defaulting to the
+  empty string) and this is used to construct a :class:`logging.Filter`
+  instance.
+
+* *handlers* - the corresponding value will be a dict in which each
+  key is a handler id and each value is a dict describing how to
+  configure the corresponding Handler instance.
+
+  The configuring dict is searched for the following keys:
+
+  * ``class`` (mandatory).  This is the fully qualified name of the
+    handler class.
+
+  * ``level`` (optional).  The level of the handler.
+
+  * ``formatter`` (optional).  The id of the formatter for this
+    handler.
+
+  * ``filters`` (optional).  A list of ids of the filters for this
+    handler.
+
+  All *other* keys are passed through as keyword arguments to the
+  handler's constructor.  For example, given the snippet::
+
+      handlers:
+        console:
+          class : logging.StreamHandler
+          formatter: brief
+          level   : INFO
+          filters: [allow_foo]
+          stream  : ext://sys.stdout
+        file:
+          class : logging.handlers.RotatingFileHandler
+          formatter: precise
+          filename: logconfig.log
+          maxBytes: 1024
+          backupCount: 3
+
+  the handler with id ``console`` is instantiated as a
+  :class:`logging.StreamHandler`, using ``sys.stdout`` as the underlying
+  stream.  The handler with id ``file`` is instantiated as a
+  :class:`logging.handlers.RotatingFileHandler` with the keyword arguments
+  ``filename='logconfig.log', maxBytes=1024, backupCount=3``.
+
+* *loggers* - the corresponding value will be a dict in which each key
+  is a logger name and each value is a dict describing how to
+  configure the corresponding Logger instance.
+
+  The configuring dict is searched for the following keys:
+
+  * ``level`` (optional).  The level of the logger.
+
+  * ``propagate`` (optional).  The propagation setting of the logger.
+
+  * ``filters`` (optional).  A list of ids of the filters for this
+    logger.
+
+  * ``handlers`` (optional).  A list of ids of the handlers for this
+    logger.
+
+  The specified loggers will be configured according to the level,
+  propagation, filters and handlers specified.
+
+* *root* - this will be the configuration for the root logger.
+  Processing of the configuration will be as for any logger, except
+  that the ``propagate`` setting will not be applicable.
+
+* *incremental* - whether the configuration is to be interpreted as
+  incremental to the existing configuration.  This value defaults to
+  ``False``, which means that the specified configuration replaces the
+  existing configuration with the same semantics as used by the
+  existing :func:`fileConfig` API.
+
+  If the specified value is ``True``, the configuration is processed
+  as described in the section on :ref:`logging-config-dict-incremental`.
+
+* *disable_existing_loggers* - whether any existing loggers are to be
+  disabled. This setting mirrors the parameter of the same name in
+  :func:`fileConfig`. If absent, this parameter defaults to ``True``.
+  This value is ignored if *incremental* is ``True``.
+
+.. _logging-config-dict-incremental:
+
+Incremental Configuration
+"""""""""""""""""""""""""
+
+It is difficult to provide complete flexibility for incremental
+configuration.  For example, because objects such as filters
+and formatters are anonymous, once a configuration is set up, it is
+not possible to refer to such anonymous objects when augmenting a
+configuration.
+
+Furthermore, there is not a compelling case for arbitrarily altering
+the object graph of loggers, handlers, filters, formatters at
+run-time, once a configuration is set up; the verbosity of loggers and
+handlers can be controlled just by setting levels (and, in the case of
+loggers, propagation flags).  Changing the object graph arbitrarily in
+a safe way is problematic in a multi-threaded environment; while not
+impossible, the benefits are not worth the complexity it adds to the
+implementation.
+
+Thus, when the ``incremental`` key of a configuration dict is present
+and is ``True``, the system will completely ignore any ``formatters`` and
+``filters`` entries, and process only the ``level``
+settings in the ``handlers`` entries, and the ``level`` and
+``propagate`` settings in the ``loggers`` and ``root`` entries.
+
+Using a value in the configuration dict lets configurations to be sent
+over the wire as pickled dicts to a socket listener. Thus, the logging
+verbosity of a long-running application can be altered over time with
+no need to stop and restart the application.
+
+.. _logging-config-dict-connections:
+
+Object connections
+""""""""""""""""""
+
+The schema describes a set of logging objects - loggers,
+handlers, formatters, filters - which are connected to each other in
+an object graph.  Thus, the schema needs to represent connections
+between the objects.  For example, say that, once configured, a
+particular logger has attached to it a particular handler.  For the
+purposes of this discussion, we can say that the logger represents the
+source, and the handler the destination, of a connection between the
+two.  Of course in the configured objects this is represented by the
+logger holding a reference to the handler.  In the configuration dict,
+this is done by giving each destination object an id which identifies
+it unambiguously, and then using the id in the source object's
+configuration to indicate that a connection exists between the source
+and the destination object with that id.
+
+So, for example, consider the following YAML snippet::
+
+    formatters:
+      brief:
+        # configuration for formatter with id 'brief' goes here
+      precise:
+        # configuration for formatter with id 'precise' goes here
+    handlers:
+      h1: #This is an id
+       # configuration of handler with id 'h1' goes here
+       formatter: brief
+      h2: #This is another id
+       # configuration of handler with id 'h2' goes here
+       formatter: precise
+    loggers:
+      foo.bar.baz:
+        # other configuration for logger 'foo.bar.baz'
+        handlers: [h1, h2]
+
+(Note: YAML used here because it's a little more readable than the
+equivalent Python source form for the dictionary.)
+
+The ids for loggers are the logger names which would be used
+programmatically to obtain a reference to those loggers, e.g.
+``foo.bar.baz``.  The ids for Formatters and Filters can be any string
+value (such as ``brief``, ``precise`` above) and they are transient,
+in that they are only meaningful for processing the configuration
+dictionary and used to determine connections between objects, and are
+not persisted anywhere when the configuration call is complete.
+
+The above snippet indicates that logger named ``foo.bar.baz`` should
+have two handlers attached to it, which are described by the handler
+ids ``h1`` and ``h2``. The formatter for ``h1`` is that described by id
+``brief``, and the formatter for ``h2`` is that described by id
+``precise``.
+
+
+.. _logging-config-dict-userdef:
+
+User-defined objects
+""""""""""""""""""""
+
+The schema supports user-defined objects for handlers, filters and
+formatters.  (Loggers do not need to have different types for
+different instances, so there is no support in this configuration
+schema for user-defined logger classes.)
+
+Objects to be configured are described by dictionaries
+which detail their configuration.  In some places, the logging system
+will be able to infer from the context how an object is to be
+instantiated, but when a user-defined object is to be instantiated,
+the system will not know how to do this.  In order to provide complete
+flexibility for user-defined object instantiation, the user needs
+to provide a 'factory' - a callable which is called with a
+configuration dictionary and which returns the instantiated object.
+This is signalled by an absolute import path to the factory being
+made available under the special key ``'()'``.  Here's a concrete
+example::
+
+    formatters:
+      brief:
+        format: '%(message)s'
+      default:
+        format: '%(asctime)s %(levelname)-8s %(name)-15s %(message)s'
+        datefmt: '%Y-%m-%d %H:%M:%S'
+      custom:
+          (): my.package.customFormatterFactory
+          bar: baz
+          spam: 99.9
+          answer: 42
+
+The above YAML snippet defines three formatters.  The first, with id
+``brief``, is a standard :class:`logging.Formatter` instance with the
+specified format string.  The second, with id ``default``, has a
+longer format and also defines the time format explicitly, and will
+result in a :class:`logging.Formatter` initialized with those two format
+strings.  Shown in Python source form, the ``brief`` and ``default``
+formatters have configuration sub-dictionaries::
+
+    {
+      'format' : '%(message)s'
+    }
+
+and::
+
+    {
+      'format' : '%(asctime)s %(levelname)-8s %(name)-15s %(message)s',
+      'datefmt' : '%Y-%m-%d %H:%M:%S'
+    }
+
+respectively, and as these dictionaries do not contain the special key
+``'()'``, the instantiation is inferred from the context: as a result,
+standard :class:`logging.Formatter` instances are created.  The
+configuration sub-dictionary for the third formatter, with id
+``custom``, is::
+
+  {
+    '()' : 'my.package.customFormatterFactory',
+    'bar' : 'baz',
+    'spam' : 99.9,
+    'answer' : 42
+  }
+
+and this contains the special key ``'()'``, which means that
+user-defined instantiation is wanted.  In this case, the specified
+factory callable will be used. If it is an actual callable it will be
+used directly - otherwise, if you specify a string (as in the example)
+the actual callable will be located using normal import mechanisms.
+The callable will be called with the **remaining** items in the
+configuration sub-dictionary as keyword arguments.  In the above
+example, the formatter with id ``custom`` will be assumed to be
+returned by the call::
+
+    my.package.customFormatterFactory(bar='baz', spam=99.9, answer=42)
+
+The key ``'()'`` has been used as the special key because it is not a
+valid keyword parameter name, and so will not clash with the names of
+the keyword arguments used in the call.  The ``'()'`` also serves as a
+mnemonic that the corresponding value is a callable.
+
+
+.. _logging-config-dict-externalobj:
+
+Access to external objects
+""""""""""""""""""""""""""
+
+There are times where a configuration needs to refer to objects
+external to the configuration, for example ``sys.stderr``.  If the
+configuration dict is constructed using Python code, this is
+straightforward, but a problem arises when the configuration is
+provided via a text file (e.g. JSON, YAML).  In a text file, there is
+no standard way to distinguish ``sys.stderr`` from the literal string
+``'sys.stderr'``.  To facilitate this distinction, the configuration
+system looks for certain special prefixes in string values and
+treat them specially.  For example, if the literal string
+``'ext://sys.stderr'`` is provided as a value in the configuration,
+then the ``ext://`` will be stripped off and the remainder of the
+value processed using normal import mechanisms.
+
+The handling of such prefixes is done in a way analogous to protocol
+handling: there is a generic mechanism to look for prefixes which
+match the regular expression ``^(?P<prefix>[a-z]+)://(?P<suffix>.*)$``
+whereby, if the ``prefix`` is recognised, the ``suffix`` is processed
+in a prefix-dependent manner and the result of the processing replaces
+the string value.  If the prefix is not recognised, then the string
+value will be left as-is.
+
+
+.. _logging-config-dict-internalobj:
+
+Access to internal objects
+""""""""""""""""""""""""""
+
+As well as external objects, there is sometimes also a need to refer
+to objects in the configuration.  This will be done implicitly by the
+configuration system for things that it knows about.  For example, the
+string value ``'DEBUG'`` for a ``level`` in a logger or handler will
+automatically be converted to the value ``logging.DEBUG``, and the
+``handlers``, ``filters`` and ``formatter`` entries will take an
+object id and resolve to the appropriate destination object.
+
+However, a more generic mechanism is needed for user-defined
+objects which are not known to the :mod:`logging` module.  For
+example, consider :class:`logging.handlers.MemoryHandler`, which takes
+a ``target`` argument which is another handler to delegate to. Since
+the system already knows about this class, then in the configuration,
+the given ``target`` just needs to be the object id of the relevant
+target handler, and the system will resolve to the handler from the
+id.  If, however, a user defines a ``my.package.MyHandler`` which has
+an ``alternate`` handler, the configuration system would not know that
+the ``alternate`` referred to a handler.  To cater for this, a generic
+resolution system allows the user to specify::
+
+    handlers:
+      file:
+        # configuration of file handler goes here
+
+      custom:
+        (): my.package.MyHandler
+        alternate: cfg://handlers.file
+
+The literal string ``'cfg://handlers.file'`` will be resolved in an
+analogous way to strings with the ``ext://`` prefix, but looking
+in the configuration itself rather than the import namespace.  The
+mechanism allows access by dot or by index, in a similar way to
+that provided by ``str.format``.  Thus, given the following snippet::
+
+    handlers:
+      email:
+        class: logging.handlers.SMTPHandler
+        mailhost: localhost
+        fromaddr: my_app@domain.tld
+        toaddrs:
+          - support_team@domain.tld
+          - dev_team@domain.tld
+        subject: Houston, we have a problem.
+
+in the configuration, the string ``'cfg://handlers'`` would resolve to
+the dict with key ``handlers``, the string ``'cfg://handlers.email``
+would resolve to the dict with key ``email`` in the ``handlers`` dict,
+and so on.  The string ``'cfg://handlers.email.toaddrs[1]`` would
+resolve to ``'dev_team.domain.tld'`` and the string
+``'cfg://handlers.email.toaddrs[0]'`` would resolve to the value
+``'support_team@domain.tld'``. The ``subject`` value could be accessed
+using either ``'cfg://handlers.email.subject'`` or, equivalently,
+``'cfg://handlers.email[subject]'``.  The latter form only needs to be
+used if the key contains spaces or non-alphanumeric characters.  If an
+index value consists only of decimal digits, access will be attempted
+using the corresponding integer value, falling back to the string
+value if needed.
+
+Given a string ``cfg://handlers.myhandler.mykey.123``, this will
+resolve to ``config_dict['handlers']['myhandler']['mykey']['123']``.
+If the string is specified as ``cfg://handlers.myhandler.mykey[123]``,
+the system will attempt to retrieve the value from
+``config_dict['handlers']['myhandler']['mykey'][123]``, and fall back
+to ``config_dict['handlers']['myhandler']['mykey']['123']`` if that
+fails.
+
+.. _logging-config-fileformat:
+
+Configuration file format
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The configuration file format understood by :func:`fileConfig` is based on
+:mod:`configparser` functionality. The file must contain sections called
+``[loggers]``, ``[handlers]`` and ``[formatters]`` which identify by name the
+entities of each type which are defined in the file. For each such entity, there
+is a separate section which identifies how that entity is configured.  Thus, for
+a logger named ``log01`` in the ``[loggers]`` section, the relevant
+configuration details are held in a section ``[logger_log01]``. Similarly, a
+handler called ``hand01`` in the ``[handlers]`` section will have its
+configuration held in a section called ``[handler_hand01]``, while a formatter
+called ``form01`` in the ``[formatters]`` section will have its configuration
+specified in a section called ``[formatter_form01]``. The root logger
+configuration must be specified in a section called ``[logger_root]``.
+
+Examples of these sections in the file are given below. ::

+   keys=form01,form02,form03,form04,form05,form06,form07,form08,form09
+
+The root logger must specify a level and a list of handlers. An example of a
+root logger section is given below. ::
+
+   [logger_root]
+   level=NOTSET
+   handlers=hand01
+
+The ``level`` entry can be one of ``DEBUG, INFO, WARNING, ERROR, CRITICAL`` or
+``NOTSET``. For the root logger only, ``NOTSET`` means that all messages will be
+logged. Level values are :func:`eval`\ uated in the context of the ``logging``
+package's namespace.
+
+The ``handlers`` entry is a comma-separated list of handler names, which must
+appear in the ``[handlers]`` section. These names must appear in the
+``[handlers]`` section and have corresponding sections in the configuration
+file.
+
+For loggers other than the root logger, some additional information is required.
+This is illustrated by the following example. ::
+
+   [logger_parser]
+   level=DEBUG
+   handlers=hand01
+   propagate=1
+   qualname=compiler.parser
+
+The ``level`` and ``handlers`` entries are interpreted as for the root logger,
+except that if a non-root logger's level is specified as ``NOTSET``, the system
+consults loggers higher up the hierarchy to determine the effective level of the
+logger. The ``propagate`` entry is set to 1 to indicate that messages must
+propagate to handlers higher up the logger hierarchy from this logger, or 0 to
+indicate that messages are **not** propagated to handlers up the hierarchy. The
+``qualname`` entry is the hierarchical channel name of the logger, that is to
+say the name used by the application to get the logger.
+
+Sections which specify handler configuration are exemplified by the following.
+::
+
+   [handler_hand01]
+   class=StreamHandler
+   level=NOTSET
+   formatter=form01
+   args=(sys.stdout,)
+
+The ``class`` entry indicates the handler's class (as determined by :func:`eval`
+in the ``logging`` package's namespace). The ``level`` is interpreted as for
+loggers, and ``NOTSET`` is taken to mean 'log everything'.
+
+The ``formatter`` entry indicates the key name of the formatter for this
+handler. If blank, a default formatter (``logging._defaultFormatter``) is used.
+If a name is specified, it must appear in the ``[formatters]`` section and have
+a corresponding section in the configuration file.
+
+The ``args`` entry, when :func:`eval`\ uated in the context of the ``logging``
+package's namespace, is the list of arguments to the constructor for the handler
+class. Refer to the constructors for the relevant handlers, or to the examples
+below, to see how typical entries are constructed. ::
+
+   [handler_hand02]
+   class=FileHandler
+   level=DEBUG
+   formatter=form02
+   args=('python.log', 'w')
+
+   [handler_hand03]
+   class=handlers.SocketHandler
+   level=INFO
+   formatter=form03
+   args=('localhost', handlers.DEFAULT_TCP_LOGGING_PORT)
+
+   [handler_hand04]
+   class=handlers.DatagramHandler
+   level=WARN
+   formatter=form04
+   args=('localhost', handlers.DEFAULT_UDP_LOGGING_PORT)
+
+   [handler_hand05]
+   class=handlers.SysLogHandler
+   level=ERROR
+   formatter=form05
+   args=(('localhost', handlers.SYSLOG_UDP_PORT), handlers.SysLogHandler.LOG_USER)
+
+   [handler_hand06]
+   class=handlers.NTEventLogHandler
+   level=CRITICAL
+   formatter=form06
+   args=('Python Application', '', 'Application')
+
+   [handler_hand07]
+   class=handlers.SMTPHandler
+   level=WARN
+   formatter=form07
+   args=('localhost', 'from@abc', ['user1@abc', 'user2@xyz'], 'Logger Subject')
+
+   [handler_hand08]
+   class=handlers.MemoryHandler
+   level=NOTSET
+   formatter=form08
+   target=
+   args=(10, ERROR)
+
+   [handler_hand09]
+   class=handlers.HTTPHandler
+   level=NOTSET
+   formatter=form09
+   args=('localhost:9022', '/log', 'GET')
+
+Sections which specify formatter configuration are typified by the following. ::
+
+   [formatter_form01]
+   format=F1 %(asctime)s %(levelname)s %(message)s
+   datefmt=
+   class=logging.Formatter
+
+The ``format`` entry is the overall format string, and the ``datefmt`` entry is
+the :func:`strftime`\ -compatible date/time format string.  If empty, the
+package substitutes ISO8601 format date/times, which is almost equivalent to
+specifying the date format string ``'%Y-%m-%d %H:%M:%S'``.  The ISO8601 format
+also specifies milliseconds, which are appended to the result of using the above
+format string, with a comma separator.  An example time in ISO8601 format is
+``2003-01-23 00:29:50,411``.
+
+The ``class`` entry is optional.  It indicates the name of the formatter's class
+(as a dotted module and class name.)  This option is useful for instantiating a
+:class:`Formatter` subclass.  Subclasses of :class:`Formatter` can present
+exception tracebacks in an expanded or condensed format.

+
+.. currentmodule:: logging
+
+The following useful handlers are provided in the package. Note that three of
+the handlers (:class:`StreamHandler`, :class:`FileHandler` and
+:class:`NullHandler`) are actually defined in the :mod:`logging` module itself,
+but have been documented here along with the other handlers.
+
+.. _stream-handler:
+
+StreamHandler
+^^^^^^^^^^^^^
+
+The :class:`StreamHandler` class, located in the core :mod:`logging` package,
+sends logging output to streams such as *sys.stdout*, *sys.stderr* or any
+file-like object (or, more precisely, any object which supports :meth:`write`
+and :meth:`flush` methods).
+
+
+.. class:: StreamHandler(stream=None)
+
+   Returns a new instance of the :class:`StreamHandler` class. If *stream* is
+   specified, the instance will use it for logging output; otherwise, *sys.stderr*
+   will be used.
+
+
+   .. method:: emit(record)
+
+      If a formatter is specified, it is used to format the record. The record
+      is then written to the stream with a terminator. If exception information
+      is present, it is formatted using :func:`traceback.print_exception` and
+      appended to the stream.
+
+
+   .. method:: flush()
+
+      Flushes the stream by calling its :meth:`flush` method. Note that the
+      :meth:`close` method is inherited from :class:`Handler` and so does
+      no output, so an explicit :meth:`flush` call may be needed at times.
+
+.. versionchanged:: 3.2
+   The ``StreamHandler`` class now has a ``terminator`` attribute, default
+   value ``'\n'``, which is used as the terminator when writing a formatted
+   record to a stream. If you don't want this newline termination, you can
+   set the handler instance's ``terminator`` attribute to the empty string.
+   In earlier versions, the terminator was hardcoded as ``'\n'``.
+
+.. _file-handler:
+
+FileHandler
+^^^^^^^^^^^
+
+The :class:`FileHandler` class, located in the core :mod:`logging` package,
+sends logging output to a disk file.  It inherits the output functionality from
+:class:`StreamHandler`.
+
+
+.. class:: FileHandler(filename, mode='a', encoding=None, delay=False)
+
+   Returns a new instance of the :class:`FileHandler` class. The specified file is
+   opened and used as the stream for logging. If *mode* is not specified,
+   :const:`'a'` is used.  If *encoding* is not *None*, it is used to open the file
+   with that encoding.  If *delay* is true, then file opening is deferred until the
+   first call to :meth:`emit`. By default, the file grows indefinitely.
+
+
+   .. method:: close()
+
+      Closes the file.
+
+
+   .. method:: emit(record)
+
+      Outputs the record to the file.
+
+
+.. _null-handler:
+
+NullHandler
+^^^^^^^^^^^
+
+.. versionadded:: 3.1
+
+The :class:`NullHandler` class, located in the core :mod:`logging` package,
+does not do any formatting or output. It is essentially a 'no-op' handler
+for use by library developers.
+
+.. class:: NullHandler()
+
+   Returns a new instance of the :class:`NullHandler` class.
+
+   .. method:: emit(record)
+
+      This method does nothing.
+
+   .. method:: handle(record)
+
+      This method does nothing.
+
+   .. method:: createLock()
+
+      This method returns ``None`` for the lock, since there is no
+      underlying I/O to which access needs to be serialized.
+
+
+See :ref:`library-config` for more information on how to use
+:class:`NullHandler`.
+
+.. _watched-file-handler:
+
+WatchedFileHandler
+^^^^^^^^^^^^^^^^^^
+
+.. currentmodule:: logging.handlers
+
+The :class:`WatchedFileHandler` class, located in the :mod:`logging.handlers`
+module, is a :class:`FileHandler` which watches the file it is logging to. If
+the file changes, it is closed and reopened using the file name.
+
+A file change can happen because of usage of programs such as *newsyslog* and
+*logrotate* which perform log file rotation. This handler, intended for use
+under Unix/Linux, watches the file to see if it has changed since the last emit.
+(A file is deemed to have changed if its device or inode have changed.) If the
+file has changed, the old file stream is closed, and the file opened to get a
+new stream.
+
+This handler is not appropriate for use under Windows, because under Windows
+open log files cannot be moved or renamed - logging opens the files with
+exclusive locks - and so there is no need for such a handler. Furthermore,
+*ST_INO* is not supported under Windows; :func:`stat` always returns zero for
+this value.
+
+
+.. class:: WatchedFileHandler(filename[,mode[, encoding[, delay]]])
+
+   Returns a new instance of the :class:`WatchedFileHandler` class. The specified
+   file is opened and used as the stream for logging. If *mode* is not specified,
+   :const:`'a'` is used.  If *encoding* is not *None*, it is used to open the file
+   with that encoding.  If *delay* is true, then file opening is deferred until the
+   first call to :meth:`emit`.  By default, the file grows indefinitely.
+
+
+   .. method:: emit(record)
+
+      Outputs the record to the file, but first checks to see if the file has
+      changed.  If it has, the existing stream is flushed and closed and the
+      file opened again, before outputting the record to the file.
+
+.. _rotating-file-handler:
+
+RotatingFileHandler
+^^^^^^^^^^^^^^^^^^^
+
+The :class:`RotatingFileHandler` class, located in the :mod:`logging.handlers`
+module, supports rotation of disk log files.
+
+
+.. class:: RotatingFileHandler(filename, mode='a', maxBytes=0, backupCount=0, encoding=None, delay=0)
+
+   Returns a new instance of the :class:`RotatingFileHandler` class. The specified
+   file is opened and used as the stream for logging. If *mode* is not specified,
+   ``'a'`` is used.  If *encoding* is not *None*, it is used to open the file
+   with that encoding.  If *delay* is true, then file opening is deferred until the
+   first call to :meth:`emit`.  By default, the file grows indefinitely.
+
+   You can use the *maxBytes* and *backupCount* values to allow the file to
+   :dfn:`rollover` at a predetermined size. When the size is about to be exceeded,
+   the file is closed and a new file is silently opened for output. Rollover occurs
+   whenever the current log file is nearly *maxBytes* in length; if *maxBytes* is
+   zero, rollover never occurs.  If *backupCount* is non-zero, the system will save
+   old log files by appending the extensions '.1', '.2' etc., to the filename. For
+   example, with a *backupCount* of 5 and a base file name of :file:`app.log`, you
+   would get :file:`app.log`, :file:`app.log.1`, :file:`app.log.2`, up to
+   :file:`app.log.5`. The file being written to is always :file:`app.log`.  When
+   this file is filled, it is closed and renamed to :file:`app.log.1`, and if files
+   :file:`app.log.1`, :file:`app.log.2`, etc.  exist, then they are renamed to
+   :file:`app.log.2`, :file:`app.log.3` etc.  respectively.
+
+
+   .. method:: doRollover()
+
+      Does a rollover, as described above.
+
+
+   .. method:: emit(record)
+
+      Outputs the record to the file, catering for rollover as described
+      previously.
+
+.. _timed-rotating-file-handler:
+
+TimedRotatingFileHandler
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+The :class:`TimedRotatingFileHandler` class, located in the
+:mod:`logging.handlers` module, supports rotation of disk log files at certain
+timed intervals.
+
+
+.. class:: TimedRotatingFileHandler(filename, when='h', interval=1, backupCount=0, encoding=None, delay=False, utc=False)
+
+   Returns a new instance of the :class:`TimedRotatingFileHandler` class. The
+   specified file is opened and used as the stream for logging. On rotating it also
+   sets the filename suffix. Rotating happens based on the product of *when* and
+   *interval*.
+
+   You can use the *when* to specify the type of *interval*. The list of possible
+   values is below.  Note that they are not case sensitive.
+
+   +----------------+-----------------------+
+   | Value          | Type of interval      |
+   +================+=======================+
+   | ``'S'``        | Seconds               |
+   +----------------+-----------------------+
+   | ``'M'``        | Minutes               |
+   +----------------+-----------------------+
+   | ``'H'``        | Hours                 |
+   +----------------+-----------------------+
+   | ``'D'``        | Days                  |
+   +----------------+-----------------------+
+   | ``'W'``        | Week day (0=Monday)   |
+   +----------------+-----------------------+
+   | ``'midnight'`` | Roll over at midnight |
+   +----------------+-----------------------+
+
+   The system will save old log files by appending extensions to the filename.
+   The extensions are date-and-time based, using the strftime format
+   ``%Y-%m-%d_%H-%M-%S`` or a leading portion thereof, depending on the
+   rollover interval.
+
+   When computing the next rollover time for the first time (when the handler
+   is created), the last modification time of an existing log file, or else
+   the current time, is used to compute when the next rotation will occur.
+
+   If the *utc* argument is true, times in UTC will be used; otherwise
+   local time is used.
+
+   If *backupCount* is nonzero, at most *backupCount* files
+   will be kept, and if more would be created when rollover occurs, the oldest
+   one is deleted. The deletion logic uses the interval to determine which
+   files to delete, so changing the interval may leave old files lying around.
+
+   If *delay* is true, then file opening is deferred until the first call to
+   :meth:`emit`.
+
+
+   .. method:: doRollover()
+
+      Does a rollover, as described above.
+
+
+   .. method:: emit(record)
+
+      Outputs the record to the file, catering for rollover as described above.
+
+
+.. _socket-handler:
+
+SocketHandler
+^^^^^^^^^^^^^
+
+The :class:`SocketHandler` class, located in the :mod:`logging.handlers` module,
+sends logging output to a network socket. The base class uses a TCP socket.
+
+
+.. class:: SocketHandler(host, port)
+
+   Returns a new instance of the :class:`SocketHandler` class intended to
+   communicate with a remote machine whose address is given by *host* and *port*.
+
+
+   .. method:: close()
+
+      Closes the socket.
+
+
+   .. method:: emit()
+
+      Pickles the record's attribute dictionary and writes it to the socket in
+      binary format. If there is an error with the socket, silently drops the
+      packet. If the connection was previously lost, re-establishes the
+      connection. To unpickle the record at the receiving end into a
+      :class:`LogRecord`, use the :func:`makeLogRecord` function.
+
+
+   .. method:: handleError()
+
+      Handles an error which has occurred during :meth:`emit`. The most likely
+      cause is a lost connection. Closes the socket so that we can retry on the
+      next event.
+
+
+   .. method:: makeSocket()
+
+      This is a factory method which allows subclasses to define the precise
+      type of socket they want. The default implementation creates a TCP socket
+      (:const:`socket.SOCK_STREAM`).
+
+
+   .. method:: makePickle(record)
+
+      Pickles the record's attribute dictionary in binary format with a length
+      prefix, and returns it ready for transmission across the socket.
+
+      Note that pickles aren't completely secure. If you are concerned about
+      security, you may want to override this method to implement a more secure
+      mechanism. For example, you can sign pickles using HMAC and then verify
+      them on the receiving end, or alternatively you can disable unpickling of
+      global objects on the receiving end.
+
+
+   .. method:: send(packet)
+
+      Send a pickled string *packet* to the socket. This function allows for
+      partial sends which can happen when the network is busy.
+
+
+   .. method:: createSocket()
+
+      Tries to create a socket; on failure, uses an exponential back-off
+      algorithm.  On intial failure, the handler will drop the message it was
+      trying to send.  When subsequent messages are handled by the same
+      instance, it will not try connecting until some time has passed.  The
+      default parameters are such that the initial delay is one second, and if
+      after that delay the connection still can't be made, the handler will
+      double the delay each time up to a maximum of 30 seconds.
+
+      This behaviour is controlled by the following handler attributes:
+
+      * ``retryStart`` (initial delay, defaulting to 1.0 seconds).
+      * ``retryFactor`` (multiplier, defaulting to 2.0).
+      * ``retryMax`` (maximum delay, defaulting to 30.0 seconds).
+
+      This means that if the remote listener starts up *after* the handler has
+      been used, you could lose messages (since the handler won't even attempt
+      a connection until the delay has elapsed, but just silently drop messages
+      during the delay period).
+
+
+.. _datagram-handler:
+
+DatagramHandler
+^^^^^^^^^^^^^^^
+
+The :class:`DatagramHandler` class, located in the :mod:`logging.handlers`
+module, inherits from :class:`SocketHandler` to support sending logging messages
+over UDP sockets.
+
+
+.. class:: DatagramHandler(host, port)
+
+   Returns a new instance of the :class:`DatagramHandler` class intended to
+   communicate with a remote machine whose address is given by *host* and *port*.
+
+
+   .. method:: emit()
+
+      Pickles the record's attribute dictionary and writes it to the socket in
+      binary format. If there is an error with the socket, silently drops the
+      packet. To unpickle the record at the receiving end into a
+      :class:`LogRecord`, use the :func:`makeLogRecord` function.
+
+
+   .. method:: makeSocket()
+
+      The factory method of :class:`SocketHandler` is here overridden to create
+      a UDP socket (:const:`socket.SOCK_DGRAM`).
+
+
+   .. method:: send(s)
+
+      Send a pickled string to a socket.
+
+
+.. _syslog-handler:
+
+SysLogHandler
+^^^^^^^^^^^^^
+
+The :class:`SysLogHandler` class, located in the :mod:`logging.handlers` module,
+supports sending logging messages to a remote or local Unix syslog.
+
+
+.. class:: SysLogHandler(address=('localhost', SYSLOG_UDP_PORT), facility=LOG_USER, socktype=socket.SOCK_DGRAM)
+
+   Returns a new instance of the :class:`SysLogHandler` class intended to
+   communicate with a remote Unix machine whose address is given by *address* in
+   the form of a ``(host, port)`` tuple.  If *address* is not specified,
+   ``('localhost', 514)`` is used.  The address is used to open a socket.  An
+   alternative to providing a ``(host, port)`` tuple is providing an address as a
+   string, for example '/dev/log'. In this case, a Unix domain socket is used to
+   send the message to the syslog. If *facility* is not specified,
+   :const:`LOG_USER` is used. The type of socket opened depends on the
+   *socktype* argument, which defaults to :const:`socket.SOCK_DGRAM` and thus
+   opens a UDP socket. To open a TCP socket (for use with the newer syslog
+   daemons such as rsyslog), specify a value of :const:`socket.SOCK_STREAM`.
+
+   Note that if your server is not listening on UDP port 514,
+   :class:`SysLogHandler` may appear not to work. In that case, check what
+   address you should be using for a domain socket - it's system dependent.
+   For example, on Linux it's usually '/dev/log' but on OS/X it's
+   '/var/run/syslog'. You'll need to check your platform and use the
+   appropriate address (you may need to do this check at runtime if your
+   application needs to run on several platforms). On Windows, you pretty
+   much have to use the UDP option.
+
+   .. versionchanged:: 3.2
+      *socktype* was added.
+
+
+   .. method:: close()
+
+      Closes the socket to the remote host.
+
+
+   .. method:: emit(record)
+
+      The record is formatted, and then sent to the syslog server. If exception
+      information is present, it is *not* sent to the server.
+
+
+   .. method:: encodePriority(facility, priority)
+
+      Encodes the facility and priority into an integer. You can pass in strings
+      or integers - if strings are passed, internal mapping dictionaries are
+      used to convert them to integers.
+
+      The symbolic ``LOG_`` values are defined in :class:`SysLogHandler` and
+      mirror the values defined in the ``sys/syslog.h`` header file.

+
+   .. method:: mapPriority(levelname)
+
+      Maps a logging level name to a syslog priority name.
+      You may need to override this if you are using custom levels, or
+      if the default algorithm is not suitable for your needs. The
+      default algorithm maps ``DEBUG``, ``INFO``, ``WARNING``, ``ERROR`` and
+      ``CRITICAL`` to the equivalent syslog names, and all other level
+      names to 'warning'.
+
+.. _nt-eventlog-handler:
+
+NTEventLogHandler
+^^^^^^^^^^^^^^^^^
+
+The :class:`NTEventLogHandler` class, located in the :mod:`logging.handlers`
+module, supports sending logging messages to a local Windows NT, Windows 2000 or
+Windows XP event log. Before you can use it, you need Mark Hammond's Win32
+extensions for Python installed.
+
+
+.. class:: NTEventLogHandler(appname, dllname=None, logtype='Application')
+
+   Returns a new instance of the :class:`NTEventLogHandler` class. The *appname* is
+   used to define the application name as it appears in the event log. An
+   appropriate registry entry is created using this name. The *dllname* should give
+   the fully qualified pathname of a .dll or .exe which contains message
+   definitions to hold in the log (if not specified, ``'win32service.pyd'`` is used
+   - this is installed with the Win32 extensions and contains some basic
+   placeholder message definitions. Note that use of these placeholders will make
+   your event logs big, as the entire message source is held in the log. If you
+   want slimmer logs, you have to pass in the name of your own .dll or .exe which
+   contains the message definitions you want to use in the event log). The
+   *logtype* is one of ``'Application'``, ``'System'`` or ``'Security'``, and
+   defaults to ``'Application'``.
+
+
+   .. method:: close()
+
+      At this point, you can remove the application name from the registry as a
+      source of event log entries. However, if you do this, you will not be able
+      to see the events as you intended in the Event Log Viewer - it needs to be
+      able to access the registry to get the .dll name. The current version does
+      not do this.
+
+
+   .. method:: emit(record)
+
+      Determines the message ID, event category and event type, and then logs
+      the message in the NT event log.
+
+
+   .. method:: getEventCategory(record)
+
+      Returns the event category for the record. Override this if you want to
+      specify your own categories. This version returns 0.
+
+
+   .. method:: getEventType(record)
+
+      Returns the event type for the record. Override this if you want to
+      specify your own types. This version does a mapping using the handler's
+      typemap attribute, which is set up in :meth:`__init__` to a dictionary
+      which contains mappings for :const:`DEBUG`, :const:`INFO`,
+      :const:`WARNING`, :const:`ERROR` and :const:`CRITICAL`. If you are using
+      your own levels, you will either need to override this method or place a
+      suitable dictionary in the handler's *typemap* attribute.
+
+
+   .. method:: getMessageID(record)
+
+      Returns the message ID for the record. If you are using your own messages,
+      you could do this by having the *msg* passed to the logger being an ID
+      rather than a format string. Then, in here, you could use a dictionary
+      lookup to get the message ID. This version returns 1, which is the base
+      message ID in :file:`win32service.pyd`.
+
+.. _smtp-handler:
+
+SMTPHandler
+^^^^^^^^^^^
+
+The :class:`SMTPHandler` class, located in the :mod:`logging.handlers` module,
+supports sending logging messages to an email address via SMTP.
+
+
+.. class:: SMTPHandler(mailhost, fromaddr, toaddrs, subject, credentials=None)
+
+   Returns a new instance of the :class:`SMTPHandler` class. The instance is
+   initialized with the from and to addresses and subject line of the email. The
+   *toaddrs* should be a list of strings. To specify a non-standard SMTP port, use
+   the (host, port) tuple format for the *mailhost* argument. If you use a string,
+   the standard SMTP port is used. If your SMTP server requires authentication, you
+   can specify a (username, password) tuple for the *credentials* argument.
+
+
+   .. method:: emit(record)
+
+      Formats the record and sends it to the specified addressees.
+
+
+   .. method:: getSubject(record)
+
+      If you want to specify a subject line which is record-dependent, override
+      this method.
+
+.. _memory-handler:
+
+MemoryHandler
+^^^^^^^^^^^^^
+
+The :class:`MemoryHandler` class, located in the :mod:`logging.handlers` module,
+supports buffering of logging records in memory, periodically flushing them to a
+:dfn:`target` handler. Flushing occurs whenever the buffer is full, or when an
+event of a certain severity or greater is seen.
+
+:class:`MemoryHandler` is a subclass of the more general
+:class:`BufferingHandler`, which is an abstract class. This buffers logging
+records in memory. Whenever each record is added to the buffer, a check is made
+by calling :meth:`shouldFlush` to see if the buffer should be flushed.  If it
+should, then :meth:`flush` is expected to do the needful.
+
+
+.. class:: BufferingHandler(capacity)
+
+   Initializes the handler with a buffer of the specified capacity.
+
+
+   .. method:: emit(record)
+
+      Appends the record to the buffer. If :meth:`shouldFlush` returns true,
+      calls :meth:`flush` to process the buffer.
+
+
+   .. method:: flush()
+
+      You can override this to implement custom flushing behavior. This version
+      just zaps the buffer to empty.
+
+
+   .. method:: shouldFlush(record)
+
+      Returns true if the buffer is up to capacity. This method can be
+      overridden to implement custom flushing strategies.
+
+
+.. class:: MemoryHandler(capacity, flushLevel=ERROR, target=None)
+
+   Returns a new instance of the :class:`MemoryHandler` class. The instance is
+   initialized with a buffer size of *capacity*. If *flushLevel* is not specified,
+   :const:`ERROR` is used. If no *target* is specified, the target will need to be
+   set using :meth:`setTarget` before this handler does anything useful.
+
+
+   .. method:: close()
+
+      Calls :meth:`flush`, sets the target to :const:`None` and clears the
+      buffer.
+
+
+   .. method:: flush()
+
+      For a :class:`MemoryHandler`, flushing means just sending the buffered
+      records to the target, if there is one. The buffer is also cleared when
+      this happens. Override if you want different behavior.
+
+
+   .. method:: setTarget(target)
+
+      Sets the target handler for this handler.
+
+
+   .. method:: shouldFlush(record)
+
+      Checks for buffer full or a record at the *flushLevel* or higher.
+
+
+.. _http-handler:
+
+HTTPHandler
+^^^^^^^^^^^
+
+The :class:`HTTPHandler` class, located in the :mod:`logging.handlers` module,
+supports sending logging messages to a Web server, using either ``GET`` or
+``POST`` semantics.
+
+
+.. class:: HTTPHandler(host, url, method='GET', secure=False, credentials=None)
+
+   Returns a new instance of the :class:`HTTPHandler` class. The *host* can be
+   of the form ``host:port``, should you need to use a specific port number.
+   If no *method* is specified, ``GET`` is used. If *secure* is True, an HTTPS
+   connection will be used. If *credentials* is specified, it should be a
+   2-tuple consisting of userid and password, which will be placed in an HTTP
+   'Authorization' header using Basic authentication. If you specify
+   credentials, you should also specify secure=True so that your userid and
+   password are not passed in cleartext across the wire.
+
+
+   .. method:: emit(record)
+
+      Sends the record to the Web server as a percent-encoded dictionary.
+
+
+.. _queue-handler:
+
+
+QueueHandler
+^^^^^^^^^^^^
+
+.. versionadded:: 3.2
+
+The :class:`QueueHandler` class, located in the :mod:`logging.handlers` module,
+supports sending logging messages to a queue, such as those implemented in the
+:mod:`queue` or :mod:`multiprocessing` modules.
+
+Along with the :class:`QueueListener` class, :class:`QueueHandler` can be used
+to let handlers do their work on a separate thread from the one which does the
+logging. This is important in Web applications and also other service
+applications where threads servicing clients need to respond as quickly as
+possible, while any potentially slow operations (such as sending an email via
+:class:`SMTPHandler`) are done on a separate thread.
+
+.. class:: QueueHandler(queue)
+
+   Returns a new instance of the :class:`QueueHandler` class. The instance is
+   initialized with the queue to send messages to. The queue can be any queue-
+   like object; it's used as-is by the :meth:`enqueue` method, which needs
+   to know how to send messages to it.
+
+
+   .. method:: emit(record)
+
+      Enqueues the result of preparing the LogRecord.
+
+   .. method:: prepare(record)
+
+      Prepares a record for queuing. The object returned by this
+      method is enqueued.
+
+      The base implementation formats the record to merge the message
+      and arguments, and removes unpickleable items from the record
+      in-place.
+
+      You might want to override this method if you want to convert
+      the record to a dict or JSON string, or send a modified copy
+      of the record while leaving the original intact.
+
+   .. method:: enqueue(record)
+
+      Enqueues the record on the queue using ``put_nowait()``; you may
+      want to override this if you want to use blocking behaviour, or a
+      timeout, or a customised queue implementation.
+
+
+
+.. queue-listener:
+
+QueueListener
+^^^^^^^^^^^^^
+
+.. versionadded:: 3.2
+
+The :class:`QueueListener` class, located in the :mod:`logging.handlers`
+module, supports receiving logging messages from a queue, such as those
+implemented in the :mod:`queue` or :mod:`multiprocessing` modules. The
+messages are received from a queue in an internal thread and passed, on
+the same thread, to one or more handlers for processing. While
+:class:`QueueListener` is not itself a handler, it is documented here
+because it works hand-in-hand with :class:`QueueHandler`.
+
+Along with the :class:`QueueHandler` class, :class:`QueueListener` can be used
+to let handlers do their work on a separate thread from the one which does the
+logging. This is important in Web applications and also other service
+applications where threads servicing clients need to respond as quickly as
+possible, while any potentially slow operations (such as sending an email via
+:class:`SMTPHandler`) are done on a separate thread.
+
+.. class:: QueueListener(queue, *handlers)
+
+   Returns a new instance of the :class:`QueueListener` class. The instance is
+   initialized with the queue to send messages to and a list of handlers which
+   will handle entries placed on the queue. The queue can be any queue-
+   like object; it's passed as-is to the :meth:`dequeue` method, which needs
+   to know how to get messages from it.
+
+   .. method:: dequeue(block)
+
+      Dequeues a record and return it, optionally blocking.
+
+      The base implementation uses ``get()``. You may want to override this
+      method if you want to use timeouts or work with custom queue
+      implementations.
+
+   .. method:: prepare(record)
+
+      Prepare a record for handling.
+
+      This implementation just returns the passed-in record. You may want to
+      override this method if you need to do any custom marshalling or
+      manipulation of the record before passing it to the handlers.
+
+   .. method:: handle(record)
+
+      Handle a record.
+
+      This just loops through the handlers offering them the record
+      to handle. The actual object passed to the handlers is that which
+      is returned from :meth:`prepare`.
+
+   .. method:: start()
+
+      Starts the listener.
+
+      This starts up a background thread to monitor the queue for
+      LogRecords to process.
+
+   .. method:: stop()
+
+      Stops the listener.
+
+      This asks the thread to terminate, and then waits for it to do so.
+      Note that if you don't call this before your application exits, there
+      may be some records still left on the queue, which won't be processed.

-Logging is performed by calling methods on instances of the :class:`Logger`
-class (hereafter called :dfn:`loggers`). Each instance has a name, and they are
-conceptually arranged in a namespace hierarchy using dots (periods) as
-separators. For example, a logger named "scan" is the parent of loggers
-"scan.text", "scan.html" and "scan.pdf". Logger names can be anything you want,

-:const:`ERROR` and :const:`CRITICAL`. As a convenience, you indicate the
-importance of a logged message by calling an appropriate method of
-:class:`Logger`. The methods are :meth:`debug`, :meth:`info`, :meth:`warning`,
-:meth:`error` and :meth:`critical`, which mirror the default levels. You are not
-constrained to use these levels: you can specify your own and use a more general
-:class:`Logger` method, :meth:`log`, which takes an explicit level argument.

-Logging tutorial
-----------------
+This module defines functions and classes which implement a flexible event
+logging system for applications and libraries.
 
 The key benefit of having the logging API provided by a standard library module
 is that all Python modules can participate in logging, so your application log
-can include messages from third-party modules.
+can include your own messages integrated with messages from third-party
+modules.
 
-It is, of course, possible to log messages with different verbosity levels or to
-different destinations.  Support for writing log messages to files, HTTP
-GET/POST locations, email via SMTP, generic sockets, or OS-specific logging
-mechanisms are all supported by the standard module.  You can also create your
-own log destination class if you have special requirements not met by any of the
-built-in classes.
+The module provides a lot of functionality and flexibility.  If you are
+unfamiliar with logging, the best way to get to grips with it is to see the
+tutorials (see the links on the right).
 
-Simple examples
-^^^^^^^^^^^^^^^
-
-.. sectionauthor:: Doug Hellmann
-.. (see <http://blog.doughellmann.com/2007/05/pymotw-logging.html>)
+The basic classes defined by the module, together with their functions, are
+listed below.
 
-Most applications are probably going to want to log to a file, so let's start
-with that case. Using the :func:`basicConfig` function, we can set up the
-default handler so that debug messages are written to a file (in the example,
-we assume that you have the appropriate permissions to create a file called
-*example.log* in the current directory)::
-
-   import logging
-   LOG_FILENAME = 'example.log'
-   logging.basicConfig(filename=LOG_FILENAME,level=logging.DEBUG)
-
-   logging.debug('This message should go to the log file')
-
-And now if we open the file and look at what we have, we should find the log
-message::
-
-   DEBUG:root:This message should go to the log file
-
-If you run the script repeatedly, the additional log messages are appended to
-the file.  To create a new file each time, you can pass a *filemode* argument to
-:func:`basicConfig` with a value of ``'w'``.  Rather than managing the file size
-yourself, though, it is simpler to use a :class:`RotatingFileHandler`::
-
-   import glob
-   import logging
-   import logging.handlers
-
-   LOG_FILENAME = 'logging_rotatingfile_example.out'
-
-   # Set up a specific logger with our desired output level
-   my_logger = logging.getLogger('MyLogger')
-   my_logger.setLevel(logging.DEBUG)
-
-   # Add the log message handler to the logger
-   handler = logging.handlers.RotatingFileHandler(
-                 LOG_FILENAME, maxBytes=20, backupCount=5)
+* Loggers expose the interface that application code directly uses.
+* Handlers send the log records (created by loggers) to the appropriate
+  destination.
+* Filters provide a finer grained facility for determining which log records
+  to output.
+* Formatters specify the layout of log records in the final output.
 
-   my_logger.addHandler(handler)
-
-   # Log some messages
-   for i in range(20):
-       my_logger.debug('i = %d' % i)
-
-   # See what files are created
-   logfiles = glob.glob('%s*' % LOG_FILENAME)
-
-   for filename in logfiles:
-       print(filename)
-
-The result should be 6 separate files, each with part of the log history for the
-application::
-
-   logging_rotatingfile_example.out
-   logging_rotatingfile_example.out.1
-   logging_rotatingfile_example.out.2
-   logging_rotatingfile_example.out.3
-   logging_rotatingfile_example.out.4
-   logging_rotatingfile_example.out.5
-
-The most current file is always :file:`logging_rotatingfile_example.out`,
-and each time it reaches the size limit it is renamed with the suffix
-``.1``. Each of the existing backup files is renamed to increment the suffix
-(``.1`` becomes ``.2``, etc.)  and the ``.6`` file is erased.
-
-Obviously this example sets the log length much much too small as an extreme
-example.  You would want to set *maxBytes* to an appropriate value.
-
-Another useful feature of the logging API is the ability to produce different
-messages at different log levels.  This allows you to instrument your code with
-debug messages, for example, but turning the log level down so that those debug
-messages are not written for your production system.  The default levels are
-``CRITICAL``, ``ERROR``, ``WARNING``, ``INFO``, ``DEBUG`` and ``NOTSET``.
-
-The logger, handler, and log message call each specify a level.  The log message
-is only emitted if the handler and logger are configured to emit messages of
-that level or lower.  For example, if a message is ``CRITICAL``, and the logger
-is set to ``ERROR``, the message is emitted.  If a message is a ``WARNING``, and
-the logger is set to produce only ``ERROR``\s, the message is not emitted::
-
-   import logging
-   import sys
-
-   LEVELS = {'debug': logging.DEBUG,
-             'info': logging.INFO,
-             'warning': logging.WARNING,
-             'error': logging.ERROR,
-             'critical': logging.CRITICAL}
-
-   if len(sys.argv) > 1:
-       level_name = sys.argv[1]
-       level = LEVELS.get(level_name, logging.NOTSET)
-       logging.basicConfig(level=level)
-
-   logging.debug('This is a debug message')
-   logging.info('This is an info message')
-   logging.warning('This is a warning message')
-   logging.error('This is an error message')
-   logging.critical('This is a critical error message')
-
-Run the script with an argument like 'debug' or 'warning' to see which messages
-show up at different levels::
-
-   $ python logging_level_example.py debug
-   DEBUG:root:This is a debug message
-   INFO:root:This is an info message
-   WARNING:root:This is a warning message
-   ERROR:root:This is an error message
-   CRITICAL:root:This is a critical error message
-
-   $ python logging_level_example.py info
-   INFO:root:This is an info message
-   WARNING:root:This is a warning message
-   ERROR:root:This is an error message
-   CRITICAL:root:This is a critical error message
-
-You will notice that these log messages all have ``root`` embedded in them.  The
-logging module supports a hierarchy of loggers with different names.  An easy
-way to tell where a specific log message comes from is to use a separate logger
-object for each of your modules.  Each new logger "inherits" the configuration
-of its parent, and log messages sent to a logger include the name of that
-logger.  Optionally, each logger can be configured differently, so that messages
-from different modules are handled in different ways.  Let's look at a simple
-example of how to log from different modules so it is easy to trace the source
-of the message::
-
-   import logging
-
-   logging.basicConfig(level=logging.WARNING)
-
-   logger1 = logging.getLogger('package1.module1')
-   logger2 = logging.getLogger('package2.module2')
-
-   logger1.warning('This message comes from one module')
-   logger2.warning('And this message comes from another module')
-
-And the output::
-
-   $ python logging_modules_example.py
-   WARNING:package1.module1:This message comes from one module
-   WARNING:package2.module2:And this message comes from another module
-
-There are many more options for configuring logging, including different log
-message formatting options, having messages delivered to multiple destinations,
-and changing the configuration of a long-running application on the fly using a
-socket interface.  All of these options are covered in depth in the library
-module documentation.
-
-Loggers
-^^^^^^^
-
-The logging library takes a modular approach and offers the several categories
-of components: loggers, handlers, filters, and formatters.  Loggers expose the
-interface that application code directly uses.  Handlers send the log records to
-the appropriate destination. Filters provide a finer grained facility for
-determining which log records to send on to a handler.  Formatters specify the
-layout of the resultant log record.
-
-:class:`Logger` objects have a threefold job.  First, they expose several
-methods to application code so that applications can log messages at runtime.
-Second, logger objects determine which log messages to act upon based upon
-severity (the default filtering facility) or filter objects.  Third, logger
-objects pass along relevant log messages to all interested log handlers.
-
-The most widely used methods on logger objects fall into two categories:
-configuration and message sending.
-
-* :meth:`Logger.setLevel` specifies the lowest-severity log message a logger
-  will handle, where debug is the lowest built-in severity level and critical is
-  the highest built-in severity.  For example, if the severity level is info,
-  the logger will handle only info, warning, error, and critical messages and
-  will ignore debug messages.
-
-* :meth:`Logger.addFilter` and :meth:`Logger.removeFilter` add and remove filter
-  objects from the logger object.  This tutorial does not address filters.
-
-With the logger object configured, the following methods create log messages:
-
-* :meth:`Logger.debug`, :meth:`Logger.info`, :meth:`Logger.warning`,
-  :meth:`Logger.error`, and :meth:`Logger.critical` all create log records with
-  a message and a level that corresponds to their respective method names. The
-  message is actually a format string, which may contain the standard string
-  substitution syntax of :const:`%s`, :const:`%d`, :const:`%f`, and so on.  The
-  rest of their arguments is a list of objects that correspond with the
-  substitution fields in the message.  With regard to :const:`**kwargs`, the
-  logging methods care only about a keyword of :const:`exc_info` and use it to
-  determine whether to log exception information.
-
-* :meth:`Logger.exception` creates a log message similar to
-  :meth:`Logger.error`.  The difference is that :meth:`Logger.exception` dumps a
-  stack trace along with it.  Call this method only from an exception handler.
-
-* :meth:`Logger.log` takes a log level as an explicit argument.  This is a
-  little more verbose for logging messages than using the log level convenience
-  methods listed above, but this is how to log at custom log levels.
-
-:func:`getLogger` returns a reference to a logger instance with the specified
-name if it is provided, or ``root`` if not.  The names are period-separated
-hierarchical structures.  Multiple calls to :func:`getLogger` with the same name
-will return a reference to the same logger object.  Loggers that are further
-down in the hierarchical list are children of loggers higher up in the list.
-For example, given a logger with a name of ``foo``, loggers with names of
-``foo.bar``, ``foo.bar.baz``, and ``foo.bam`` are all descendants of ``foo``.
-Child loggers propagate messages up to the handlers associated with their
-ancestor loggers.  Because of this, it is unnecessary to define and configure
-handlers for all the loggers an application uses. It is sufficient to
-configure handlers for a top-level logger and create child loggers as needed.
-
-
-Handlers
-^^^^^^^^
-
-:class:`Handler` objects are responsible for dispatching the appropriate log
-messages (based on the log messages' severity) to the handler's specified
-destination.  Logger objects can add zero or more handler objects to themselves
-with an :func:`addHandler` method.  As an example scenario, an application may
-want to send all log messages to a log file, all log messages of error or higher
-to stdout, and all messages of critical to an email address.  This scenario
-requires three individual handlers where each handler is responsible for sending
-messages of a specific severity to a specific location.
-
-The standard library includes quite a few handler types; this tutorial uses only
-:class:`StreamHandler` and :class:`FileHandler` in its examples.
-
-There are very few methods in a handler for application developers to concern
-themselves with.  The only handler methods that seem relevant for application
-developers who are using the built-in handler objects (that is, not creating
-custom handlers) are the following configuration methods:
-
-* The :meth:`Handler.setLevel` method, just as in logger objects, specifies the
-  lowest severity that will be dispatched to the appropriate destination.  Why
-  are there two :func:`setLevel` methods?  The level set in the logger
-  determines which severity of messages it will pass to its handlers.  The level
-  set in each handler determines which messages that handler will send on.
-
-* :func:`setFormatter` selects a Formatter object for this handler to use.
-
-* :func:`addFilter` and :func:`removeFilter` respectively configure and
-  deconfigure filter objects on handlers.
-
-Application code should not directly instantiate and use instances of
-:class:`Handler`.  Instead, the :class:`Handler` class is a base class that
-defines the interface that all handlers should have and establishes some
-default behavior that child classes can use (or override).
-
-
-Formatters
-^^^^^^^^^^
-
-Formatter objects configure the final order, structure, and contents of the log
-message.  Unlike the base :class:`logging.Handler` class, application code may
-instantiate formatter classes, although you could likely subclass the formatter
-if your application needs special behavior.  The constructor takes two optional
-arguments: a message format string and a date format string.  If there is no
-message format string, the default is to use the raw message.  If there is no
-date format string, the default date format is::
-
-    %Y-%m-%d %H:%M:%S
-
-with the milliseconds tacked on at the end.
-
-The message format string uses ``%(<dictionary key>)s`` styled string
-substitution; the possible keys are documented in :ref:`formatter-objects`.
-
-The following message format string will log the time in a human-readable
-format, the severity of the message, and the contents of the message, in that
-order::
-
-    "%(asctime)s - %(levelname)s - %(message)s"
-
-Formatters use a user-configurable function to convert the creation time of a
-record to a tuple. By default, :func:`time.localtime` is used; to change this
-for a particular formatter instance, set the ``converter`` attribute of the
-instance to a function with the same signature as :func:`time.localtime` or
-:func:`time.gmtime`. To change it for all formatters, for example if you want
-all logging times to be shown in GMT, set the ``converter`` attribute in the
-Formatter class (to ``time.gmtime`` for GMT display).
-
-
-Configuring Logging
-^^^^^^^^^^^^^^^^^^^
-
-Programmers can configure logging either by creating loggers, handlers, and
-formatters explicitly in a main module with the configuration methods listed
-above (using Python code), or by creating a logging config file.  The following
-code is an example of configuring a very simple logger, a console handler, and a
-simple formatter in a Python module::
-
-    import logging
-
-    # create logger
-    logger = logging.getLogger("simple_example")
-    logger.setLevel(logging.DEBUG)
-    # create console handler and set level to debug
-    ch = logging.StreamHandler()
-    ch.setLevel(logging.DEBUG)
-    # create formatter
-    formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
-    # add formatter to ch
-    ch.setFormatter(formatter)
-    # add ch to logger
-    logger.addHandler(ch)
-
-    # "application" code
-    logger.debug("debug message")
-    logger.info("info message")
-    logger.warn("warn message")
-    logger.error("error message")
-    logger.critical("critical message")
-
-Running this module from the command line produces the following output::
-
-    $ python simple_logging_module.py
-    2005-03-19 15:10:26,618 - simple_example - DEBUG - debug message
-    2005-03-19 15:10:26,620 - simple_example - INFO - info message
-    2005-03-19 15:10:26,695 - simple_example - WARNING - warn message
-    2005-03-19 15:10:26,697 - simple_example - ERROR - error message
-    2005-03-19 15:10:26,773 - simple_example - CRITICAL - critical message
-
-The following Python module creates a logger, handler, and formatter nearly
-identical to those in the example listed above, with the only difference being
-the names of the objects::
-
-    import logging
-    import logging.config
-
-    logging.config.fileConfig("logging.conf")
-
-    # create logger
-    logger = logging.getLogger("simpleExample")
-
-    # "application" code
-    logger.debug("debug message")
-    logger.info("info message")
-    logger.warn("warn message")
-    logger.error("error message")
-    logger.critical("critical message")
-
-Here is the logging.conf file::
-
-    [loggers]
-    keys=root,simpleExample
-
-    [handlers]
-    keys=consoleHandler
-
-    [formatters]
-    keys=simpleFormatter
-
-    [logger_root]
-    level=DEBUG
-    handlers=consoleHandler
-
-    [logger_simpleExample]
-    level=DEBUG
-    handlers=consoleHandler
-    qualname=simpleExample
-    propagate=0
-
-    [handler_consoleHandler]
-    class=StreamHandler
-    level=DEBUG
-    formatter=simpleFormatter
-    args=(sys.stdout,)
-
-    [formatter_simpleFormatter]
-    format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
-    datefmt=
-
-The output is nearly identical to that of the non-config-file-based example::
-
-    $ python simple_logging_config.py
-    2005-03-19 15:38:55,977 - simpleExample - DEBUG - debug message
-    2005-03-19 15:38:55,979 - simpleExample - INFO - info message
-    2005-03-19 15:38:56,054 - simpleExample - WARNING - warn message
-    2005-03-19 15:38:56,055 - simpleExample - ERROR - error message
-    2005-03-19 15:38:56,130 - simpleExample - CRITICAL - critical message
-
-You can see that the config file approach has a few advantages over the Python
-code approach, mainly separation of configuration and code and the ability of
-noncoders to easily modify the logging properties.
-
-.. _library-config:
-
-Configuring Logging for a Library
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-When developing a library which uses logging, some consideration needs to be
-given to its configuration. If the using application does not use logging, and
-library code makes logging calls, then a one-off message "No handlers could be
-found for logger X.Y.Z" is printed to the console. This message is intended
-to catch mistakes in logging configuration, but will confuse an application
-developer who is not aware of logging by the library.
-
-In addition to documenting how a library uses logging, a good way to configure
-library logging so that it does not cause a spurious message is to add a
-handler which does nothing. This avoids the message being printed, since a
-handler will be found: it just doesn't produce any output. If the library user
-configures logging for application use, presumably that configuration will add
-some handlers, and if levels are suitably configured then logging calls made
-in library code will send output to those handlers, as normal.
-
-A do-nothing handler can be simply defined as follows::
-
-    import logging
-
-    class NullHandler(logging.Handler):
-        def emit(self, record):
-            pass
-
-An instance of this handler should be added to the top-level logger of the
-logging namespace used by the library. If all logging by a library *foo* is
-done using loggers with names matching "foo.x.y", then the code::
-
-    import logging
-
-    h = NullHandler()
-    logging.getLogger("foo").addHandler(h)
-
-should have the desired effect. If an organisation produces a number of
-libraries, then the logger name specified can be "orgname.foo" rather than
-just "foo".
-
-.. versionadded:: 3.1
-   The :class:`NullHandler` class.
-
-
-Logging Levels
---------------
-
-The numeric values of logging levels are given in the following table. These are
-primarily of interest if you want to define your own levels, and need them to
-have specific values relative to the predefined levels. If you define a level
-with the same numeric value, it overwrites the predefined value; the predefined
-name is lost.
-
-+--------------+---------------+
-| Level        | Numeric value |
-+==============+===============+
-| ``CRITICAL`` | 50            |
-+--------------+---------------+
-| ``ERROR``    | 40            |
-+--------------+---------------+
-| ``WARNING``  | 30            |
-+--------------+---------------+
-| ``INFO``     | 20            |
-+--------------+---------------+
-| ``DEBUG``    | 10            |
-+--------------+---------------+
-| ``NOTSET``   | 0             |
-+--------------+---------------+
-
-Levels can also be associated with loggers, being set either by the developer or
-through loading a saved logging configuration. When a logging method is called
-on a logger, the logger compares its own level with the level associated with
-the method call. If the logger's level is higher than the method call's, no
-logging message is actually generated. This is the basic mechanism controlling
-the verbosity of logging output.
-
-Logging messages are encoded as instances of the :class:`LogRecord` class. When
-a logger decides to actually log an event, a :class:`LogRecord` instance is
-created from the logging message.
-
-Logging messages are subjected to a dispatch mechanism through the use of
-:dfn:`handlers`, which are instances of subclasses of the :class:`Handler`
-class. Handlers are responsible for ensuring that a logged message (in the form
-of a :class:`LogRecord`) ends up in a particular location (or set of locations)
-which is useful for the target audience for that message (such as end users,
-support desk staff, system administrators, developers). Handlers are passed
-:class:`LogRecord` instances intended for particular destinations. Each logger
-can have zero, one or more handlers associated with it (via the
-:meth:`addHandler` method of :class:`Logger`). In addition to any handlers
-directly associated with a logger, *all handlers associated with all ancestors
-of the logger* are called to dispatch the message (unless the *propagate* flag
-for a logger is set to a false value, at which point the passing to ancestor
-handlers stops).
-
-Just as for loggers, handlers can have levels associated with them. A handler's
-level acts as a filter in the same way as a logger's level does. If a handler
-decides to actually dispatch an event, the :meth:`emit` method is used to send
-the message to its destination. Most user-defined subclasses of :class:`Handler`
-will need to override this :meth:`emit`.
-
-Useful Handlers
----------------
-
-In addition to the base :class:`Handler` class, many useful subclasses are
-provided:
-
-#. :class:`StreamHandler` instances send messages to streams (file-like
-   objects).
-
-#. :class:`FileHandler` instances send messages to disk files.
-
-.. module:: logging.handlers
-
-#. :class:`BaseRotatingHandler` is the base class for handlers that
-   rotate log files at a certain point. It is not meant to be  instantiated
-   directly. Instead, use :class:`RotatingFileHandler` or
-   :class:`TimedRotatingFileHandler`.
-
-#. :class:`RotatingFileHandler` instances send messages to disk
-   files, with support for maximum log file sizes and log file rotation.
-
-#. :class:`TimedRotatingFileHandler` instances send messages to
-   disk files, rotating the log file at certain timed intervals.
-
-#. :class:`SocketHandler` instances send messages to TCP/IP
-   sockets.
-
-#. :class:`DatagramHandler` instances send messages to UDP
-   sockets.
-
-#. :class:`SMTPHandler` instances send messages to a designated
-   email address.
-
-#. :class:`SysLogHandler` instances send messages to a Unix
-   syslog daemon, possibly on a remote machine.
-
-#. :class:`NTEventLogHandler` instances send messages to a
-   Windows NT/2000/XP event log.
-
-#. :class:`MemoryHandler` instances send messages to a buffer
-   in memory, which is flushed whenever specific criteria are met.
-
-#. :class:`HTTPHandler` instances send messages to an HTTP
-   server using either ``GET`` or ``POST`` semantics.
-
-#. :class:`WatchedFileHandler` instances watch the file they are
-   logging to. If the file changes, it is closed and reopened using the file
-   name. This handler is only useful on Unix-like systems; Windows does not
-   support the underlying mechanism used.
-
-.. currentmodule:: logging
-
-#. :class:`NullHandler` instances do nothing with error messages. They are used
-   by library developers who want to use logging, but want to avoid the "No
-   handlers could be found for logger XXX" message which can be displayed if
-   the library user has not configured logging. See :ref:`library-config` for
-   more information.
-
-.. versionadded:: 3.1
-   The :class:`NullHandler` class.
-
-The :class:`NullHandler`, :class:`StreamHandler` and :class:`FileHandler`
-classes are defined in the core logging package. The other handlers are
-defined in a sub- module, :mod:`logging.handlers`. (There is also another
-sub-module, :mod:`logging.config`, for configuration functionality.)
-
-Logged messages are formatted for presentation through instances of the
-:class:`Formatter` class. They are initialized with a format string suitable for
-use with the % operator and a dictionary.
-
-For formatting multiple messages in a batch, instances of
-:class:`BufferingFormatter` can be used. In addition to the format string (which
-is applied to each message in the batch), there is provision for header and
-trailer format strings.
-
-When filtering based on logger level and/or handler level is not enough,
-instances of :class:`Filter` can be added to both :class:`Logger` and
-:class:`Handler` instances (through their :meth:`addFilter` method). Before
-deciding to process a message further, both loggers and handlers consult all
-their filters for permission. If any filter returns a false value, the message
-is not processed further.
-
-The basic :class:`Filter` functionality allows filtering by specific logger
-name. If this feature is used, messages sent to the named logger and its
-children are allowed through the filter, and all others dropped.
-
-Module-Level Functions
-----------------------
-
-In addition to the classes described above, there are a number of module- level
-functions.
-
-
-.. function:: getLogger(name=None)
-
-   Return a logger with the specified name or, if name is ``None``, return a
-   logger which is the root logger of the hierarchy. If specified, the name is
-   typically a dot-separated hierarchical name like *"a"*, *"a.b"* or *"a.b.c.d"*.
-   Choice of these names is entirely up to the developer who is using logging.
-
-   All calls to this function with a given name return the same logger instance.
-   This means that logger instances never need to be passed between different parts
-   of an application.
-
-
-.. function:: getLoggerClass()
-
-   Return either the standard :class:`Logger` class, or the last class passed to
-   :func:`setLoggerClass`. This function may be called from within a new class
-   definition, to ensure that installing a customised :class:`Logger` class will
-   not undo customisations already applied by other code. For example::
-
-      class MyLogger(logging.getLoggerClass()):
-          # ... override behaviour here
-
-
-.. function:: debug(msg, *args, **kwargs)
-
-   Logs a message with level :const:`DEBUG` on the root logger. The *msg* is the
-   message format string, and the *args* are the arguments which are merged into
-   *msg* using the string formatting operator. (Note that this means that you can
-   use keywords in the format string, together with a single dictionary argument.)
-
-   There are two keyword arguments in *kwargs* which are inspected: *exc_info*
-   which, if it does not evaluate as false, causes exception information to be
-   added to the logging message. If an exception tuple (in the format returned by
-   :func:`sys.exc_info`) is provided, it is used; otherwise, :func:`sys.exc_info`
-   is called to get the exception information.
-
-   The other optional keyword argument is *extra* which can be used to pass a
-   dictionary which is used to populate the __dict__ of the LogRecord created for
-   the logging event with user-defined attributes. These custom attributes can then
-   be used as you like. For example, they could be incorporated into logged
-   messages. For example::
-
-      FORMAT = "%(asctime)-15s %(clientip)s %(user)-8s %(message)s"
-      logging.basicConfig(format=FORMAT)
-      d = {'clientip': '192.168.0.1', 'user': 'fbloggs'}
-      logging.warning("Protocol problem: %s", "connection reset", extra=d)
-
-   would print something like::
-
-      2006-02-08 22:20:02,165 192.168.0.1 fbloggs  Protocol problem: connection reset
-
-   The keys in the dictionary passed in *extra* should not clash with the keys used
-   by the logging system. (See the :class:`Formatter` documentation for more
-   information on which keys are used by the logging system.)
-
-   If you choose to use these attributes in logged messages, you need to exercise
-   some care. In the above example, for instance, the :class:`Formatter` has been
-   set up with a format string which expects 'clientip' and 'user' in the attribute
-   dictionary of the LogRecord. If these are missing, the message will not be
-   logged because a string formatting exception will occur. So in this case, you
-   always need to pass the *extra* dictionary with these keys.
-
-   While this might be annoying, this feature is intended for use in specialized
-   circumstances, such as multi-threaded servers where the same code executes in
-   many contexts, and interesting conditions which arise are dependent on this
-   context (such as remote client IP address and authenticated user name, in the
-   above example). In such circumstances, it is likely that specialized
-   :class:`Formatter`\ s would be used with particular :class:`Handler`\ s.
-
-
-.. function:: info(msg, *args, **kwargs)
-
-   Logs a message with level :const:`INFO` on the root logger. The arguments are
-   interpreted as for :func:`debug`.
-
-
-.. function:: warning(msg, *args, **kwargs)
-
-   Logs a message with level :const:`WARNING` on the root logger. The arguments are
-   interpreted as for :func:`debug`.
-
-
-.. function:: error(msg, *args, **kwargs)
-
-   Logs a message with level :const:`ERROR` on the root logger. The arguments are
-   interpreted as for :func:`debug`.
-
-
-.. function:: critical(msg, *args, **kwargs)
-
-   Logs a message with level :const:`CRITICAL` on the root logger. The arguments
-   are interpreted as for :func:`debug`.
-
-
-.. function:: exception(msg, *args)
-
-   Logs a message with level :const:`ERROR` on the root logger. The arguments are
-   interpreted as for :func:`debug`. Exception info is added to the logging
-   message. This function should only be called from an exception handler.
-
-
-.. function:: log(level, msg, *args, **kwargs)
-
-   Logs a message with level *level* on the root logger. The other arguments are
-   interpreted as for :func:`debug`.
-
-
-.. function:: disable(lvl)
-
-   Provides an overriding level *lvl* for all loggers which takes precedence over
-   the logger's own level. When the need arises to temporarily throttle logging
-   output down across the whole application, this function can be useful. Its
-   effect is to disable all logging calls of severity *lvl* and below, so that
-   if you call it with a value of INFO, then all INFO and DEBUG events would be
-   discarded, whereas those of severity WARNING and above would be processed
-   according to the logger's effective level.
-
-
-.. function:: addLevelName(lvl, levelName)
-
-   Associates level *lvl* with text *levelName* in an internal dictionary, which is
-   used to map numeric levels to a textual representation, for example when a
-   :class:`Formatter` formats a message. This function can also be used to define
-   your own levels. The only constraints are that all levels used must be
-   registered using this function, levels should be positive integers and they
-   should increase in increasing order of severity.
-
-
-.. function:: getLevelName(lvl)
-
-   Returns the textual representation of logging level *lvl*. If the level is one
-   of the predefined levels :const:`CRITICAL`, :const:`ERROR`, :const:`WARNING`,
-   :const:`INFO` or :const:`DEBUG` then you get the corresponding string. If you
-   have associated levels with names using :func:`addLevelName` then the name you
-   have associated with *lvl* is returned. If a numeric value corresponding to one
-   of the defined levels is passed in, the corresponding string representation is
-   returned. Otherwise, the string "Level %s" % lvl is returned.
-
-
-.. function:: makeLogRecord(attrdict)
-
-   Creates and returns a new :class:`LogRecord` instance whose attributes are
-   defined by *attrdict*. This function is useful for taking a pickled
-   :class:`LogRecord` attribute dictionary, sent over a socket, and reconstituting
-   it as a :class:`LogRecord` instance at the receiving end.
-
-
-.. function:: basicConfig(**kwargs)
-
-   Does basic configuration for the logging system by creating a
-   :class:`StreamHandler` with a default :class:`Formatter` and adding it to the
-   root logger. The functions :func:`debug`, :func:`info`, :func:`warning`,
-   :func:`error` and :func:`critical` will call :func:`basicConfig` automatically
-   if no handlers are defined for the root logger.
-
-   This function does nothing if the root logger already has handlers
-   configured for it.
-
-   The following keyword arguments are supported.
-
-   +--------------+---------------------------------------------+
-   | Format       | Description                                 |
-   +==============+=============================================+
-   | ``filename`` | Specifies that a FileHandler be created,    |
-   |              | using the specified filename, rather than a |
-   |              | StreamHandler.                              |
-   +--------------+---------------------------------------------+
-   | ``filemode`` | Specifies the mode to open the file, if     |
-   |              | filename is specified (if filemode is       |
-   |              | unspecified, it defaults to 'a').           |
-   +--------------+---------------------------------------------+
-   | ``format``   | Use the specified format string for the     |
-   |              | handler.                                    |
-   +--------------+---------------------------------------------+
-   | ``datefmt``  | Use the specified date/time format.         |
-   +--------------+---------------------------------------------+
-   | ``level``    | Set the root logger level to the specified  |
-   |              | level.                                      |
-   +--------------+---------------------------------------------+
-   | ``stream``   | Use the specified stream to initialize the  |
-   |              | StreamHandler. Note that this argument is   |
-   |              | incompatible with 'filename' - if both are  |
-   |              | present, 'stream' is ignored.               |
-   +--------------+---------------------------------------------+
-
-
-.. function:: shutdown()
-

-Basic example
--------------
-
-The :mod:`logging` package provides a lot of flexibility, and its configuration
-can appear daunting.  This section demonstrates that simple use of the logging
-package is possible.
-
-The simplest example shows logging to the console::
-
-   import logging
-
-   logging.debug('A debug message')
-   logging.info('Some information')
-   logging.warning('A shot across the bows')
-
-If you run the above script, you'll see this::
-
-   WARNING:root:A shot across the bows
-
-Because no particular logger was specified, the system used the root logger. The
-debug and info messages didn't appear because by default, the root logger is
-configured to only handle messages with a severity of WARNING or above. The
-message format is also a configuration default, as is the output destination of
-the messages - ``sys.stderr``. The severity level, the message format and
-destination can be easily changed, as shown in the example below::
+   Checks to see if this logger has any handlers configured. This is done by
+   looking for handlers in this logger and its parents in the logger hierarchy.
+   Returns True if a handler was found, else False. The method stops searching
+   up the hierarchy whenever a logger with the 'propagate' attribute set to
+   False is found - that will be the last logger which is checked for the
+   existence of handlers.
 
-   import logging
+   .. versionadded:: 3.2
 
-   logging.basicConfig(level=logging.DEBUG,
-                       format='%(asctime)s %(levelname)s %(message)s',
-                       filename='myapp.log',
-                       filemode='w')
-   logging.debug('A debug message')
-   logging.info('Some information')
-   logging.warning('A shot across the bows')
-
-The :meth:`basicConfig` method is used to change the configuration defaults,
-which results in output (written to ``myapp.log``) which should look
-something like the following::
-
-   2004-07-02 13:00:08,743 DEBUG A debug message
-   2004-07-02 13:00:08,743 INFO Some information
-   2004-07-02 13:00:08,743 WARNING A shot across the bows
-
-This time, all messages with a severity of DEBUG or above were handled, and the
-format of the messages was also changed, and output went to the specified file
-rather than the console.
-
-.. XXX logging should probably be updated for new string formatting!
-
-Formatting uses the old Python string formatting - see section
-:ref:`old-string-formatting`. The format string takes the following common
-specifiers. For a complete list of specifiers, consult the :class:`Formatter`
-documentation.
-
-+-------------------+-----------------------------------------------+
-| Format            | Description                                   |
-+===================+===============================================+
-| ``%(name)s``      | Name of the logger (logging channel).         |
-+-------------------+-----------------------------------------------+
-| ``%(levelname)s`` | Text logging level for the message            |
-|                   | (``'DEBUG'``, ``'INFO'``, ``'WARNING'``,      |
-|                   | ``'ERROR'``, ``'CRITICAL'``).                 |
-+-------------------+-----------------------------------------------+
-| ``%(asctime)s``   | Human-readable time when the                  |
-|                   | :class:`LogRecord` was created.  By default   |
-|                   | this is of the form "2003-07-08 16:49:45,896" |
-|                   | (the numbers after the comma are millisecond  |
-|                   | portion of the time).                         |
-+-------------------+-----------------------------------------------+
-| ``%(message)s``   | The logged message.                           |
-+-------------------+-----------------------------------------------+
-
-To change the date/time format, you can pass an additional keyword parameter,
-*datefmt*, as in the following::
-
-   import logging
-
-   logging.basicConfig(level=logging.DEBUG,
-                       format='%(asctime)s %(levelname)-8s %(message)s',
-                       datefmt='%a, %d %b %Y %H:%M:%S',
-                       filename='/temp/myapp.log',
-                       filemode='w')
-   logging.debug('A debug message')
-   logging.info('Some information')
-   logging.warning('A shot across the bows')
-
-which would result in output like ::
-
-   Fri, 02 Jul 2004 13:06:18 DEBUG    A debug message
-   Fri, 02 Jul 2004 13:06:18 INFO     Some information
-   Fri, 02 Jul 2004 13:06:18 WARNING  A shot across the bows
-
-The date format string follows the requirements of :func:`strftime` - see the
-documentation for the :mod:`time` module.
-
-If, instead of sending logging output to the console or a file, you'd rather use
-a file-like object which you have created separately, you can pass it to
-:func:`basicConfig` using the *stream* keyword argument. Note that if both
-*stream* and *filename* keyword arguments are passed, the *stream* argument is
-ignored.
-
-Of course, you can put variable information in your output. To do this, simply
-have the message be a format string and pass in additional arguments containing
-the variable information, as in the following example::
-
-   import logging
-
-   logging.basicConfig(level=logging.DEBUG,
-                       format='%(asctime)s %(levelname)-8s %(message)s',
-                       datefmt='%a, %d %b %Y %H:%M:%S',
-                       filename='/temp/myapp.log',
-                       filemode='w')
-   logging.error('Pack my box with %d dozen %s', 5, 'liquor jugs')
-
-which would result in ::
-
-   Wed, 21 Jul 2004 15:35:16 ERROR    Pack my box with 5 dozen liquor jugs
-
-
-.. _multiple-destinations:
-
-Logging to multiple destinations
---------------------------------
-
-Let's say you want to log to console and file with different message formats and
-in differing circumstances. Say you want to log messages with levels of DEBUG
-and higher to file, and those messages at level INFO and higher to the console.
-Let's also assume that the file should contain timestamps, but the console
-messages should not. Here's how you can achieve this::
-
-   import logging
-
-   # set up logging to file - see previous section for more details
-   logging.basicConfig(level=logging.DEBUG,
-                       format='%(asctime)s %(name)-12s %(levelname)-8s %(message)s',
-                       datefmt='%m-%d %H:%M',
-                       filename='/temp/myapp.log',
-                       filemode='w')
-   # define a Handler which writes INFO messages or higher to the sys.stderr
-   console = logging.StreamHandler()
-   console.setLevel(logging.INFO)
-   # set a format which is simpler for console use
-   formatter = logging.Formatter('%(name)-12s: %(levelname)-8s %(message)s')
-   # tell the handler to use this format
-   console.setFormatter(formatter)
-   # add the handler to the root logger
-   logging.getLogger('').addHandler(console)
-
-   # Now, we can log to the root logger, or any other logger. First the root...
-   logging.info('Jackdaws love my big sphinx of quartz.')
-
-   # Now, define a couple of other loggers which might represent areas in your
-   # application:
-
-   logger1 = logging.getLogger('myapp.area1')
-   logger2 = logging.getLogger('myapp.area2')
-
-   logger1.debug('Quick zephyrs blow, vexing daft Jim.')
-   logger1.info('How quickly daft jumping zebras vex.')
-   logger2.warning('Jail zesty vixen who grabbed pay from quack.')
-   logger2.error('The five boxing wizards jump quickly.')
-
-When you run this, on the console you will see ::
-
-   root        : INFO     Jackdaws love my big sphinx of quartz.
-   myapp.area1 : INFO     How quickly daft jumping zebras vex.
-   myapp.area2 : WARNING  Jail zesty vixen who grabbed pay from quack.
-   myapp.area2 : ERROR    The five boxing wizards jump quickly.
-
-and in the file you will see something like ::
-
-   10-22 22:19 root         INFO     Jackdaws love my big sphinx of quartz.
-   10-22 22:19 myapp.area1  DEBUG    Quick zephyrs blow, vexing daft Jim.
-   10-22 22:19 myapp.area1  INFO     How quickly daft jumping zebras vex.
-   10-22 22:19 myapp.area2  WARNING  Jail zesty vixen who grabbed pay from quack.
-   10-22 22:19 myapp.area2  ERROR    The five boxing wizards jump quickly.
-
-As you can see, the DEBUG message only shows up in the file. The other messages
-are sent to both destinations.
-
-This example uses console and file handlers, but you can use any number and
-combination of handlers you choose.
-
-.. _logging-exceptions:
-
-Exceptions raised during logging
---------------------------------
-
-The logging package is designed to swallow exceptions which occur while logging
-in production. This is so that errors which occur while handling logging events
-- such as logging misconfiguration, network or other similar errors - do not
-cause the application using logging to terminate prematurely.
-
-:class:`SystemExit` and :class:`KeyboardInterrupt` exceptions are never
-swallowed. Other exceptions which occur during the :meth:`emit` method of a
-:class:`Handler` subclass are passed to its :meth:`handleError` method.
-
-The default implementation of :meth:`handleError` in :class:`Handler` checks
-to see if a module-level variable, :data:`raiseExceptions`, is set. If set, a
-traceback is printed to :data:`sys.stderr`. If not set, the exception is swallowed.
-
-**Note:** The default value of :data:`raiseExceptions` is ``True``. This is because
-during development, you typically want to be notified of any exceptions that
-occur. It's advised that you set :data:`raiseExceptions` to ``False`` for production
-usage.
-
-.. _context-info:
-
-Adding contextual information to your logging output
-----------------------------------------------------
-
-Sometimes you want logging output to contain contextual information in
-addition to the parameters passed to the logging call. For example, in a
-networked application, it may be desirable to log client-specific information
-in the log (e.g. remote client's username, or IP address). Although you could
-use the *extra* parameter to achieve this, it's not always convenient to pass
-the information in this way. While it might be tempting to create
-:class:`Logger` instances on a per-connection basis, this is not a good idea
-because these instances are not garbage collected. While this is not a problem
-in practice, when the number of :class:`Logger` instances is dependent on the
-level of granularity you want to use in logging an application, it could
-be hard to manage if the number of :class:`Logger` instances becomes
-effectively unbounded.
-
-
-Using LoggerAdapters to impart contextual information
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-An easy way in which you can pass contextual information to be output along
-with logging event information is to use the :class:`LoggerAdapter` class.
-This class is designed to look like a :class:`Logger`, so that you can call
-:meth:`debug`, :meth:`info`, :meth:`warning`, :meth:`error`,
-:meth:`exception`, :meth:`critical` and :meth:`log`. These methods have the
-same signatures as their counterparts in :class:`Logger`, so you can use the
-two types of instances interchangeably.
-
-When you create an instance of :class:`LoggerAdapter`, you pass it a
-:class:`Logger` instance and a dict-like object which contains your contextual
-information. When you call one of the logging methods on an instance of
-:class:`LoggerAdapter`, it delegates the call to the underlying instance of
-:class:`Logger` passed to its constructor, and arranges to pass the contextual
-information in the delegated call. Here's a snippet from the code of
-:class:`LoggerAdapter`::
-
-    def debug(self, msg, *args, **kwargs):
-        """
-        Delegate a debug call to the underlying logger, after adding
-        contextual information from this adapter instance.
-        """
-        msg, kwargs = self.process(msg, kwargs)
-        self.logger.debug(msg, *args, **kwargs)
-
-The :meth:`process` method of :class:`LoggerAdapter` is where the contextual
-information is added to the logging output. It's passed the message and
-keyword arguments of the logging call, and it passes back (potentially)
-modified versions of these to use in the call to the underlying logger. The
-default implementation of this method leaves the message alone, but inserts
-an "extra" key in the keyword argument whose value is the dict-like object
-passed to the constructor. Of course, if you had passed an "extra" keyword
-argument in the call to the adapter, it will be silently overwritten.
-
-The advantage of using "extra" is that the values in the dict-like object are
-merged into the :class:`LogRecord` instance's __dict__, allowing you to use
-customized strings with your :class:`Formatter` instances which know about
-the keys of the dict-like object. If you need a different method, e.g. if you
-want to prepend or append the contextual information to the message string,
-you just need to subclass :class:`LoggerAdapter` and override :meth:`process`
-to do what you need. Here's an example script which uses this class, which
-also illustrates what dict-like behaviour is needed from an arbitrary
-"dict-like" object for use in the constructor::
-
-   import logging
-
-   class ConnInfo:
-       """
-       An example class which shows how an arbitrary class can be used as
-       the 'extra' context information repository passed to a LoggerAdapter.
-       """
-
-       def __getitem__(self, name):
-           """
-           To allow this instance to look like a dict.
-           """
-           from random import choice

-           else:

-       logging.basicConfig(level=logging.DEBUG,

-           lvlname = logging.getLevelName(lvl)
-           a2.log(lvl, "A message at %s level with %d %s", lvlname, 2, "parameters")

-Using Filters to impart contextual information
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-You can also add contextual information to log output using a user-defined
-:class:`Filter`. ``Filter`` instances are allowed to modify the ``LogRecords``
-passed to them, including adding additional attributes which can then be output
-using a suitable format string, or if needed a custom :class:`Formatter`.
-
-For example in a web application, the request being processed (or at least,
-the interesting parts of it) can be stored in a threadlocal
-(:class:`threading.local`) variable, and then accessed from a ``Filter`` to
-add, say, information from the request - say, the remote IP address and remote
-user's username - to the ``LogRecord``, using the attribute names 'ip' and
-'user' as in the ``LoggerAdapter`` example above. In that case, the same format
-string can be used to get similar output to that shown above. Here's an example
-script::
-
-    import logging
-    from random import choice
-
-    class ContextFilter(logging.Filter):
-        """
-        This is a filter which injects contextual information into the log.
-
-        Rather than use actual contextual information, we just use random
-        data in this demo.
-        """
-
-        USERS = ['jim', 'fred', 'sheila']
-        IPS = ['123.231.231.123', '127.0.0.1', '192.168.0.1']
-
-        def filter(self, record):
-
-            record.ip = choice(ContextFilter.IPS)
-            record.user = choice(ContextFilter.USERS)
-            return True
-
-    if __name__ == "__main__":
-       levels = (logging.DEBUG, logging.INFO, logging.WARNING, logging.ERROR, logging.CRITICAL)
-       a1 = logging.LoggerAdapter(logging.getLogger("a.b.c"),
-                                  { "ip" : "123.231.231.123", "user" : "sheila" })
-       logging.basicConfig(level=logging.DEBUG,
-                           format="%(asctime)-15s %(name)-5s %(levelname)-8s IP: %(ip)-15s User: %(user)-8s %(message)s")

-       a2.addFilter(f)
-       a1.debug("A debug message")
-       a1.info("An info message with %s", "some parameters")
-       for x in range(10):
-           lvl = choice(levels)
-           lvlname = logging.getLevelName(lvl)

-.. _multiple-processes:
-
-Logging to a single file from multiple processes
-------------------------------------------------
-
-Although logging is thread-safe, and logging to a single file from multiple
-threads in a single process *is* supported, logging to a single file from
-*multiple processes* is *not* supported, because there is no standard way to
-serialize access to a single file across multiple processes in Python. If you
-need to log to a single file from multiple processes, one way of doing this is
-to have all the processes log to a :class:`SocketHandler`, and have a separate
-process which implements a socket server which reads from the socket and logs
-to file. (If you prefer, you can dedicate one thread in one of the existing
-processes to perform this function.) The following section documents this
-approach in more detail and includes a working socket receiver which can be
-used as a starting point for you to adapt in your own applications.
-
-If you are using a recent version of Python which includes the
-:mod:`multiprocessing` module, you could write your own handler which uses the
-:class:`Lock` class from this module to serialize access to the file from
-your processes. The existing :class:`FileHandler` and subclasses do not make
-use of :mod:`multiprocessing` at present, though they may do so in the future.
-Note that at present, the :mod:`multiprocessing` module does not provide
-working lock functionality on all platforms (see
-http://bugs.python.org/issue3770).
-
-
-.. _network-logging:
-
-Sending and receiving logging events across a network
------------------------------------------------------
-
-Let's say you want to send logging events across a network, and handle them at
-the receiving end. A simple way of doing this is attaching a
-:class:`SocketHandler` instance to the root logger at the sending end::
-
-   import logging, logging.handlers
-
-   rootLogger = logging.getLogger('')
-   rootLogger.setLevel(logging.DEBUG)
-   socketHandler = logging.handlers.SocketHandler('localhost',
-                       logging.handlers.DEFAULT_TCP_LOGGING_PORT)
-   # don't bother with a formatter, since a socket handler sends the event as
-   # an unformatted pickle
-   rootLogger.addHandler(socketHandler)
-
-   # Now, we can log to the root logger, or any other logger. First the root...
-   logging.info('Jackdaws love my big sphinx of quartz.')
-
-   # Now, define a couple of other loggers which might represent areas in your
-   # application:
-
-   logger1 = logging.getLogger('myapp.area1')
-   logger2 = logging.getLogger('myapp.area2')
-
-   logger1.debug('Quick zephyrs blow, vexing daft Jim.')
-   logger1.info('How quickly daft jumping zebras vex.')
-   logger2.warning('Jail zesty vixen who grabbed pay from quack.')
-   logger2.error('The five boxing wizards jump quickly.')
-
-At the receiving end, you can set up a receiver using the :mod:`socketserver`
-module. Here is a basic working example::
-
-   import pickle
-   import logging
-   import logging.handlers
-   import socketserver
-   import struct
-
-
-   class LogRecordStreamHandler(socketserver.StreamRequestHandler):
-       """Handler for a streaming logging request.
-
-       This basically logs the record using whatever logging policy is
-       configured locally.
-       """
-
-       def handle(self):
-           """
-           Handle multiple requests - each expected to be a 4-byte length,
-           followed by the LogRecord in pickle format. Logs the record
-           according to whatever policy is configured locally.
-           """
-           while True:
-               chunk = self.connection.recv(4)
-               if len(chunk) < 4:
-                   break
-               slen = struct.unpack(">L", chunk)[0]
-               chunk = self.connection.recv(slen)
-               while len(chunk) < slen:
-                   chunk = chunk + self.connection.recv(slen - len(chunk))
-               obj = self.unPickle(chunk)
-               record = logging.makeLogRecord(obj)

-               name = self.server.logname
-           else:

-           # is normally called AFTER logger-level filtering. If you want
-           # to do filtering, do it at the client end to save wasting
-           # cycles and network bandwidth!

-
-Note that there are some security issues with pickle in some scenarios. If
-these affect you, you can use an alternative serialization scheme by overriding
-the :meth:`makePickle` method and implementing your alternative there, as
-well as adapting the above script to use your alternative serialization.
-
-.. _arbitrary-object-messages:
-
-Using arbitrary objects as messages
------------------------------------
-
-In the preceding sections and examples, it has been assumed that the message
-passed when logging the event is a string. However, this is not the only
-possibility. You can pass an arbitrary object as a message, and its
-:meth:`__str__` method will be called when the logging system needs to convert
-it to a string representation. In fact, if you want to, you can avoid
-computing a string representation altogether - for example, the
-:class:`SocketHandler` emits an event by pickling it and sending it over the
-wire.
-
-Optimization
-------------
-
-Formatting of message arguments is deferred until it cannot be avoided.
-However, computing the arguments passed to the logging method can also be
-expensive, and you may want to avoid doing it if the logger will just throw
-away your event. To decide what to do, you can call the :meth:`isEnabledFor`
-method which takes a level argument and returns true if the event would be
-created by the Logger for that level of call. You can write code like this::
-
-    if logger.isEnabledFor(logging.DEBUG):
-        logger.debug("Message with %s, %s", expensive_func1(),
-                                            expensive_func2())
-
-so that if the logger's threshold is set above ``DEBUG``, the calls to
-:func:`expensive_func1` and :func:`expensive_func2` are never made.
-
-There are other optimizations which can be made for specific applications which
-need more precise control over what logging information is collected. Here's a
-list of things you can do to avoid processing during logging which you don't
-need:
-
-+-----------------------------------------------+----------------------------------------+
-| What you don't want to collect                | How to avoid collecting it             |
-+===============================================+========================================+
-| Information about where calls were made from. | Set ``logging._srcfile`` to ``None``.  |
-+-----------------------------------------------+----------------------------------------+
-| Threading information.                        | Set ``logging.logThreads`` to ``0``.   |
-+-----------------------------------------------+----------------------------------------+
-| Process information.                          | Set ``logging.logProcesses`` to ``0``. |
-+-----------------------------------------------+----------------------------------------+
-
-Also note that the core logging module only includes the basic handlers. If
-you don't import :mod:`logging.handlers` and :mod:`logging.config`, they won't
-take up any memory.

-
-.. _stream-handler:
-
-StreamHandler
-^^^^^^^^^^^^^
-
-The :class:`StreamHandler` class, located in the core :mod:`logging` package,
-sends logging output to streams such as *sys.stdout*, *sys.stderr* or any
-file-like object (or, more precisely, any object which supports :meth:`write`
-and :meth:`flush` methods).
-
-
-.. currentmodule:: logging
-
-.. class:: StreamHandler(stream=None)
-
-   Returns a new instance of the :class:`StreamHandler` class. If *stream* is
-   specified, the instance will use it for logging output; otherwise, *sys.stderr*
-   will be used.
-
-
-   .. method:: emit(record)
-
-      If a formatter is specified, it is used to format the record. The record
-      is then written to the stream with a trailing newline. If exception
-      information is present, it is formatted using
-      :func:`traceback.print_exception` and appended to the stream.
-
-
-   .. method:: flush()
-
-      Flushes the stream by calling its :meth:`flush` method. Note that the
-      :meth:`close` method is inherited from :class:`Handler` and so does
-      no output, so an explicit :meth:`flush` call may be needed at times.
-
-
-.. _file-handler:
-
-FileHandler
-^^^^^^^^^^^
-
-The :class:`FileHandler` class, located in the core :mod:`logging` package,
-sends logging output to a disk file.  It inherits the output functionality from
-:class:`StreamHandler`.
-
-
-.. class:: FileHandler(filename, mode='a', encoding=None, delay=0)
-
-   Returns a new instance of the :class:`FileHandler` class. The specified file is
-   opened and used as the stream for logging. If *mode* is not specified,
-   :const:`'a'` is used.  If *encoding* is not *None*, it is used to open the file
-   with that encoding.  If *delay* is true, then file opening is deferred until the
-   first call to :meth:`emit`. By default, the file grows indefinitely.
-
-
-   .. method:: close()
-
-      Closes the file.
-
-
-   .. method:: emit(record)
-
-      Outputs the record to the file.
-
-
-.. _null-handler:
-
-NullHandler
-^^^^^^^^^^^
-
-.. versionadded:: 3.1
-
-The :class:`NullHandler` class, located in the core :mod:`logging` package,
-does not do any formatting or output. It is essentially a "no-op" handler
-for use by library developers.
-
-.. class:: NullHandler()
-
-   Returns a new instance of the :class:`NullHandler` class.
-
-   .. method:: emit(record)
-
-      This method does nothing.
-
-See :ref:`library-config` for more information on how to use
-:class:`NullHandler`.
-
-.. _watched-file-handler:
-
-WatchedFileHandler
-^^^^^^^^^^^^^^^^^^
-
-.. currentmodule:: logging.handlers
-
-The :class:`WatchedFileHandler` class, located in the :mod:`logging.handlers`
-module, is a :class:`FileHandler` which watches the file it is logging to. If
-the file changes, it is closed and reopened using the file name.
-
-A file change can happen because of usage of programs such as *newsyslog* and
-*logrotate* which perform log file rotation. This handler, intended for use
-under Unix/Linux, watches the file to see if it has changed since the last emit.
-(A file is deemed to have changed if its device or inode have changed.) If the
-file has changed, the old file stream is closed, and the file opened to get a
-new stream.
-
-This handler is not appropriate for use under Windows, because under Windows
-open log files cannot be moved or renamed - logging opens the files with
-exclusive locks - and so there is no need for such a handler. Furthermore,
-*ST_INO* is not supported under Windows; :func:`stat` always returns zero for
-this value.
-
-
-.. class:: WatchedFileHandler(filename[,mode[, encoding[, delay]]])
-
-   Returns a new instance of the :class:`WatchedFileHandler` class. The specified
-   file is opened and used as the stream for logging. If *mode* is not specified,
-   :const:`'a'` is used.  If *encoding* is not *None*, it is used to open the file
-   with that encoding.  If *delay* is true, then file opening is deferred until the
-   first call to :meth:`emit`.  By default, the file grows indefinitely.
-
-
-   .. method:: emit(record)
-
-      Outputs the record to the file, but first checks to see if the file has
-      changed.  If it has, the existing stream is flushed and closed and the
-      file opened again, before outputting the record to the file.
-
-.. _rotating-file-handler:
-
-RotatingFileHandler
-^^^^^^^^^^^^^^^^^^^
-
-The :class:`RotatingFileHandler` class, located in the :mod:`logging.handlers`
-module, supports rotation of disk log files.
-
-
-.. class:: RotatingFileHandler(filename, mode='a', maxBytes=0, backupCount=0, encoding=None, delay=0)
-
-   Returns a new instance of the :class:`RotatingFileHandler` class. The specified
-   file is opened and used as the stream for logging. If *mode* is not specified,
-   ``'a'`` is used.  If *encoding* is not *None*, it is used to open the file
-   with that encoding.  If *delay* is true, then file opening is deferred until the
-   first call to :meth:`emit`.  By default, the file grows indefinitely.
-
-   You can use the *maxBytes* and *backupCount* values to allow the file to
-   :dfn:`rollover` at a predetermined size. When the size is about to be exceeded,
-   the file is closed and a new file is silently opened for output. Rollover occurs
-   whenever the current log file is nearly *maxBytes* in length; if *maxBytes* is
-   zero, rollover never occurs.  If *backupCount* is non-zero, the system will save
-   old log files by appending the extensions ".1", ".2" etc., to the filename. For
-   example, with a *backupCount* of 5 and a base file name of :file:`app.log`, you
-   would get :file:`app.log`, :file:`app.log.1`, :file:`app.log.2`, up to
-   :file:`app.log.5`. The file being written to is always :file:`app.log`.  When
-   this file is filled, it is closed and renamed to :file:`app.log.1`, and if files
-   :file:`app.log.1`, :file:`app.log.2`, etc.  exist, then they are renamed to
-   :file:`app.log.2`, :file:`app.log.3` etc.  respectively.
-
-
-   .. method:: doRollover()
-
-      Does a rollover, as described above.
-
-
-   .. method:: emit(record)
-
-      Outputs the record to the file, catering for rollover as described
-      previously.
-
-.. _timed-rotating-file-handler:
-
-TimedRotatingFileHandler
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-The :class:`TimedRotatingFileHandler` class, located in the
-:mod:`logging.handlers` module, supports rotation of disk log files at certain
-timed intervals.
-
-
-.. class:: TimedRotatingFileHandler(filename, when='h', interval=1, backupCount=0, encoding=None, delay=0, utc=False)
-
-   Returns a new instance of the :class:`TimedRotatingFileHandler` class. The
-   specified file is opened and used as the stream for logging. On rotating it also
-   sets the filename suffix. Rotating happens based on the product of *when* and
-   *interval*.
-
-   You can use the *when* to specify the type of *interval*. The list of possible
-   values is below.  Note that they are not case sensitive.
-
-   +----------------+-----------------------+
-   | Value          | Type of interval      |
-   +================+=======================+

-
-   The system will save old log files by appending extensions to the filename.
-   The extensions are date-and-time based, using the strftime format
-   ``%Y-%m-%d_%H-%M-%S`` or a leading portion thereof, depending on the
-   rollover interval.
-
-   When computing the next rollover time for the first time (when the handler
-   is created), the last modification time of an existing log file, or else
-   the current time, is used to compute when the next rotation will occur.
-
-   If the *utc* argument is true, times in UTC will be used; otherwise
-   local time is used.
-
-   If *backupCount* is nonzero, at most *backupCount* files
-   will be kept, and if more would be created when rollover occurs, the oldest
-   one is deleted. The deletion logic uses the interval to determine which
-   files to delete, so changing the interval may leave old files lying around.
-
-   If *delay* is true, then file opening is deferred until the first call to
-   :meth:`emit`.
-
-
-   .. method:: doRollover()
-
-      Does a rollover, as described above.
-
-
-   .. method:: emit(record)
-
-      Outputs the record to the file, catering for rollover as described above.
-
-
-.. _socket-handler:
-
-SocketHandler
-^^^^^^^^^^^^^
-
-The :class:`SocketHandler` class, located in the :mod:`logging.handlers` module,
-sends logging output to a network socket. The base class uses a TCP socket.
-
-
-.. class:: SocketHandler(host, port)
-
-   Returns a new instance of the :class:`SocketHandler` class intended to
-   communicate with a remote machine whose address is given by *host* and *port*.
-
-
-   .. method:: close()
-
-      Closes the socket.
-
-
-   .. method:: emit()
-
-      Pickles the record's attribute dictionary and writes it to the socket in
-      binary format. If there is an error with the socket, silently drops the
-      packet. If the connection was previously lost, re-establishes the
-      connection. To unpickle the record at the receiving end into a
-      :class:`LogRecord`, use the :func:`makeLogRecord` function.
-
-
-   .. method:: handleError()
-
-      Handles an error which has occurred during :meth:`emit`. The most likely
-      cause is a lost connection. Closes the socket so that we can retry on the
-      next event.
-
-
-   .. method:: makeSocket()
-
-      This is a factory method which allows subclasses to define the precise
-      type of socket they want. The default implementation creates a TCP socket
-      (:const:`socket.SOCK_STREAM`).
-
-
-   .. method:: makePickle(record)
-
-      Pickles the record's attribute dictionary in binary format with a length
-      prefix, and returns it ready for transmission across the socket.
-
-      Note that pickles aren't completely secure. If you are concerned about
-      security, you may want to override this method to implement a more secure
-      mechanism. For example, you can sign pickles using HMAC and then verify
-      them on the receiving end, or alternatively you can disable unpickling of
-      global objects on the receiving end.
-
-   .. method:: send(packet)
-
-      Send a pickled string *packet* to the socket. This function allows for
-      partial sends which can happen when the network is busy.
-
-
-.. _datagram-handler:
-
-DatagramHandler
-^^^^^^^^^^^^^^^
-
-The :class:`DatagramHandler` class, located in the :mod:`logging.handlers`
-module, inherits from :class:`SocketHandler` to support sending logging messages
-over UDP sockets.
-
-
-.. class:: DatagramHandler(host, port)
-
-   Returns a new instance of the :class:`DatagramHandler` class intended to
-   communicate with a remote machine whose address is given by *host* and *port*.
-
-
-   .. method:: emit()
-
-      Pickles the record's attribute dictionary and writes it to the socket in
-      binary format. If there is an error with the socket, silently drops the
-      packet. To unpickle the record at the receiving end into a
-      :class:`LogRecord`, use the :func:`makeLogRecord` function.
-
-
-   .. method:: makeSocket()
-
-      The factory method of :class:`SocketHandler` is here overridden to create
-      a UDP socket (:const:`socket.SOCK_DGRAM`).
-
-
-   .. method:: send(s)
-
-      Send a pickled string to a socket.
-
-
-.. _syslog-handler:
-
-SysLogHandler
-^^^^^^^^^^^^^
-
-The :class:`SysLogHandler` class, located in the :mod:`logging.handlers` module,
-supports sending logging messages to a remote or local Unix syslog.
-
-
-.. class:: SysLogHandler(address=('localhost', SYSLOG_UDP_PORT), facility=LOG_USER)
-
-   Returns a new instance of the :class:`SysLogHandler` class intended to
-   communicate with a remote Unix machine whose address is given by *address* in
-   the form of a ``(host, port)`` tuple.  If *address* is not specified,
-   ``('localhost', 514)`` is used.  The address is used to open a UDP socket.  An
-   alternative to providing a ``(host, port)`` tuple is providing an address as a
-   string, for example "/dev/log". In this case, a Unix domain socket is used to
-   send the message to the syslog. If *facility* is not specified,
-   :const:`LOG_USER` is used.
-
-
-   .. method:: close()
-
-      Closes the socket to the remote host.
-
-
-   .. method:: emit(record)
-
-      The record is formatted, and then sent to the syslog server. If exception
-      information is present, it is *not* sent to the server.
-
-
-   .. method:: encodePriority(facility, priority)
-
-      Encodes the facility and priority into an integer. You can pass in strings
-      or integers - if strings are passed, internal mapping dictionaries are
-      used to convert them to integers.
-
-      The symbolic ``LOG_`` values are defined in :class:`SysLogHandler` and
-      mirror the values defined in the ``sys/syslog.h`` header file.

-
-   .. method:: mapPriority(levelname)
-
-      Maps a logging level name to a syslog priority name.
-      You may need to override this if you are using custom levels, or
-      if the default algorithm is not suitable for your needs. The
-      default algorithm maps ``DEBUG``, ``INFO``, ``WARNING``, ``ERROR`` and
-      ``CRITICAL`` to the equivalent syslog names, and all other level
-      names to "warning".
-
-.. _nt-eventlog-handler:
-
-NTEventLogHandler
-^^^^^^^^^^^^^^^^^
-
-The :class:`NTEventLogHandler` class, located in the :mod:`logging.handlers`
-module, supports sending logging messages to a local Windows NT, Windows 2000 or
-Windows XP event log. Before you can use it, you need Mark Hammond's Win32
-extensions for Python installed.
-
-
-.. class:: NTEventLogHandler(appname, dllname=None, logtype='Application')
-
-   Returns a new instance of the :class:`NTEventLogHandler` class. The *appname* is
-   used to define the application name as it appears in the event log. An
-   appropriate registry entry is created using this name. The *dllname* should give
-   the fully qualified pathname of a .dll or .exe which contains message
-   definitions to hold in the log (if not specified, ``'win32service.pyd'`` is used
-   - this is installed with the Win32 extensions and contains some basic
-   placeholder message definitions. Note that use of these placeholders will make
-   your event logs big, as the entire message source is held in the log. If you
-   want slimmer logs, you have to pass in the name of your own .dll or .exe which
-   contains the message definitions you want to use in the event log). The
-   *logtype* is one of ``'Application'``, ``'System'`` or ``'Security'``, and
-   defaults to ``'Application'``.
-
-
-   .. method:: close()
-
-      At this point, you can remove the application name from the registry as a
-      source of event log entries. However, if you do this, you will not be able
-      to see the events as you intended in the Event Log Viewer - it needs to be
-      able to access the registry to get the .dll name. The current version does
-      not do this.
-
-
-   .. method:: emit(record)
-
-      Determines the message ID, event category and event type, and then logs
-      the message in the NT event log.
-
-
-   .. method:: getEventCategory(record)
-
-      Returns the event category for the record. Override this if you want to
-      specify your own categories. This version returns 0.
-
-
-   .. method:: getEventType(record)
-
-      Returns the event type for the record. Override this if you want to
-      specify your own types. This version does a mapping using the handler's
-      typemap attribute, which is set up in :meth:`__init__` to a dictionary
-      which contains mappings for :const:`DEBUG`, :const:`INFO`,
-      :const:`WARNING`, :const:`ERROR` and :const:`CRITICAL`. If you are using
-      your own levels, you will either need to override this method or place a
-      suitable dictionary in the handler's *typemap* attribute.
-
-
-   .. method:: getMessageID(record)
-
-      Returns the message ID for the record. If you are using your own messages,
-      you could do this by having the *msg* passed to the logger being an ID
-      rather than a format string. Then, in here, you could use a dictionary
-      lookup to get the message ID. This version returns 1, which is the base
-      message ID in :file:`win32service.pyd`.
-
-.. _smtp-handler:
-
-SMTPHandler
-^^^^^^^^^^^
-
-The :class:`SMTPHandler` class, located in the :mod:`logging.handlers` module,
-supports sending logging messages to an email address via SMTP.
-
-
-.. class:: SMTPHandler(mailhost, fromaddr, toaddrs, subject, credentials=None)
-
-   Returns a new instance of the :class:`SMTPHandler` class. The instance is
-   initialized with the from and to addresses and subject line of the email. The
-   *toaddrs* should be a list of strings. To specify a non-standard SMTP port, use
-   the (host, port) tuple format for the *mailhost* argument. If you use a string,
-   the standard SMTP port is used. If your SMTP server requires authentication, you
-   can specify a (username, password) tuple for the *credentials* argument.
-
-
-   .. method:: emit(record)
-
-      Formats the record and sends it to the specified addressees.
-
-
-   .. method:: getSubject(record)
-
-      If you want to specify a subject line which is record-dependent, override
-      this method.
-
-.. _memory-handler:
-
-MemoryHandler
-^^^^^^^^^^^^^
-
-The :class:`MemoryHandler` class, located in the :mod:`logging.handlers` module,
-supports buffering of logging records in memory, periodically flushing them to a
-:dfn:`target` handler. Flushing occurs whenever the buffer is full, or when an
-event of a certain severity or greater is seen.
-
-:class:`MemoryHandler` is a subclass of the more general
-:class:`BufferingHandler`, which is an abstract class. This buffers logging
-records in memory. Whenever each record is added to the buffer, a check is made
-by calling :meth:`shouldFlush` to see if the buffer should be flushed.  If it
-should, then :meth:`flush` is expected to do the needful.
-
-
-.. class:: BufferingHandler(capacity)
-
-   Initializes the handler with a buffer of the specified capacity.
-
-
-   .. method:: emit(record)
-
-      Appends the record to the buffer. If :meth:`shouldFlush` returns true,
-      calls :meth:`flush` to process the buffer.
-
-
-   .. method:: flush()
-
-      You can override this to implement custom flushing behavior. This version
-      just zaps the buffer to empty.
-
-
-   .. method:: shouldFlush(record)
-
-      Returns true if the buffer is up to capacity. This method can be
-      overridden to implement custom flushing strategies.
-
-
-.. class:: MemoryHandler(capacity, flushLevel=ERROR, target=None)
-
-   Returns a new instance of the :class:`MemoryHandler` class. The instance is
-   initialized with a buffer size of *capacity*. If *flushLevel* is not specified,
-   :const:`ERROR` is used. If no *target* is specified, the target will need to be
-   set using :meth:`setTarget` before this handler does anything useful.
-
-
-   .. method:: close()
-
-      Calls :meth:`flush`, sets the target to :const:`None` and clears the
-      buffer.
-
-
-   .. method:: flush()
-
-      For a :class:`MemoryHandler`, flushing means just sending the buffered
-      records to the target, if there is one. Override if you want different
-      behavior.
-
-
-   .. method:: setTarget(target)
-
-      Sets the target handler for this handler.
-
-
-   .. method:: shouldFlush(record)
-
-      Checks for buffer full or a record at the *flushLevel* or higher.
-
-
-.. _http-handler:
-
-HTTPHandler
-^^^^^^^^^^^
-
-The :class:`HTTPHandler` class, located in the :mod:`logging.handlers` module,
-supports sending logging messages to a Web server, using either ``GET`` or
-``POST`` semantics.
-
-
-.. class:: HTTPHandler(host, url, method='GET')
-
-   Returns a new instance of the :class:`HTTPHandler` class. The instance is
-   initialized with a host address, url and HTTP method. The *host* can be of the
-   form ``host:port``, should you need to use a specific port number. If no
-   *method* is specified, ``GET`` is used.
-
-
-   .. method:: emit(record)
-
-      Sends the record to the Web server as a percent-encoded dictionary.
-

+LogRecord attributes
+--------------------
+
+The LogRecord has a number of attributes, most of which are derived from the

+attributes.) These attributes can be used to merge data from the record into
+the format string. The following table lists (in alphabetical order) the
+attribute names, their meanings and the corresponding placeholder in a %-style
+format string.
+
+If you are using {}-formatting (:func:`str.format`), you can use
+``{attrname}`` as the placeholder in the format string. If you are using
+$-formatting (:class:`string.Template`), use the form ``${attrname}``. In
+both cases, of course, replace ``attrname`` with the actual attribute name
+you want to use.
+
+In the case of {}-formatting, you can specify formatting flags by placing them
+after the attribute name, separated from it with a colon. For example: a
+placeholder of ``{msecs:03d}`` would format a millisecond value of ``4`` as
+``004``. Refer to the :meth:`str.format` documentation for full details on

+functions.
+
+
+.. function:: getLogger(name=None)
 
-Configuration functions
-^^^^^^^^^^^^^^^^^^^^^^^
+   Return a logger with the specified name or, if name is ``None``, return a
+   logger which is the root logger of the hierarchy. If specified, the name is
+   typically a dot-separated hierarchical name like *'a'*, *'a.b'* or *'a.b.c.d'*.
+   Choice of these names is entirely up to the developer who is using logging.
+
+   All calls to this function with a given name return the same logger instance.
+   This means that logger instances never need to be passed between different parts
+   of an application.
 
-The following functions configure the logging module. They are located in the
-:mod:`logging.config` module.  Their use is optional --- you can configure the
-logging module using these functions or by making calls to the main API (defined
-in :mod:`logging` itself) and defining handlers which are declared either in
-:mod:`logging` or :mod:`logging.handlers`.
 
+.. function:: getLoggerClass()
 
-.. function:: fileConfig(fname, defaults=None, disable_existing_loggers=True)
+   Return either the standard :class:`Logger` class, or the last class passed to
+   :func:`setLoggerClass`. This function may be called from within a new class
+   definition, to ensure that installing a customised :class:`Logger` class will
+   not undo customisations already applied by other code. For example::
 
-   Reads the logging configuration from a :mod:`configparser`\-format file named
-   *fname*. This function can be called several times from an application,
-   allowing an end user the ability to select from various pre-canned
-   configurations (if the developer provides a mechanism to present the choices
-   and load the chosen configuration). Defaults to be passed to the ConfigParser
-   can be specified in the *defaults* argument.
+      class MyLogger(logging.getLoggerClass()):
+          # ... override behaviour here
 
-   If *disable_existing_loggers* is true, any existing loggers that are not
-   children of named loggers will be disabled.
 
+.. function:: getLogRecordFactory()
 
-.. function:: listen(port=DEFAULT_LOGGING_CONFIG_PORT)
+   Return a callable which is used to create a :class:`LogRecord`.
 
-   Starts up a socket server on the specified port, and listens for new
-   configurations. If no port is specified, the module's default
-   :const:`DEFAULT_LOGGING_CONFIG_PORT` is used. Logging configurations will be
-   sent as a file suitable for processing by :func:`fileConfig`. Returns a
-   :class:`Thread` instance on which you can call :meth:`start` to start the
-   server, and which you can :meth:`join` when appropriate. To stop the server,
-   call :func:`stopListening`.
+   .. versionadded:: 3.2
+      This function has been provided, along with :func:`setLogRecordFactory`,
+      to allow developers more control over how the :class:`LogRecord`
+      representing a logging event is constructed.
 
-   To send a configuration to the socket, read in the configuration file and
-   send it to the socket as a string of bytes preceded by a four-byte length
-   string packed in binary using ``struct.pack('>L', n)``.
+   See :func:`setLogRecordFactory` for more information about the how the
+   factory is called.
 
+.. function:: debug(msg, *args, **kwargs)
 
-.. function:: stopListening()
+   Logs a message with level :const:`DEBUG` on the root logger. The *msg* is the
+   message format string, and the *args* are the arguments which are merged into
+   *msg* using the string formatting operator. (Note that this means that you can
+   use keywords in the format string, together with a single dictionary argument.)
 
-   Stops the listening server which was created with a call to :func:`listen`.
-   This is typically called before calling :meth:`join` on the return value from
-   :func:`listen`.
+   There are three keyword arguments in *kwargs* which are inspected: *exc_info*
+   which, if it does not evaluate as false, causes exception information to be
+   added to the logging message. If an exception tuple (in the format returned by
+   :func:`sys.exc_info`) is provided, it is used; otherwise, :func:`sys.exc_info`
+   is called to get the exception information.
 
+   The second optional keyword argument is *stack_info*, which defaults to
+   False. If specified as True, stack information is added to the logging
+   message, including the actual logging call. Note that this is not the same
+   stack information as that displayed through specifying *exc_info*: The
+   former is stack frames from the bottom of the stack up to the logging call
+   in the current thread, whereas the latter is information about stack frames
+   which have been unwound, following an exception, while searching for
+   exception handlers.
 
-.. _logging-config-fileformat:
+   You can specify *stack_info* independently of *exc_info*, e.g. to just show
+   how you got to a certain point in your code, even when no exceptions were
+   raised. The stack frames are printed following a header line which says::
 
-Configuration file format
-^^^^^^^^^^^^^^^^^^^^^^^^^
+       Stack (most recent call last):
 
-The configuration file format understood by :func:`fileConfig` is based on
-:mod:`configparser` functionality. The file must contain sections called
-``[loggers]``, ``[handlers]`` and ``[formatters]`` which identify by name the
-entities of each type which are defined in the file. For each such entity, there
-is a separate section which identifies how that entity is configured.  Thus, for
-a logger named ``log01`` in the ``[loggers]`` section, the relevant
-configuration details are held in a section ``[logger_log01]``. Similarly, a
-handler called ``hand01`` in the ``[handlers]`` section will have its
-configuration held in a section called ``[handler_hand01]``, while a formatter
-called ``form01`` in the ``[formatters]`` section will have its configuration
-specified in a section called ``[formatter_form01]``. The root logger
-configuration must be specified in a section called ``[logger_root]``.
+   This mimics the `Traceback (most recent call last):` which is used when
+   displaying exception frames.
 
-Examples of these sections in the file are given below. ::
-
-   [loggers]
-   keys=root,log02,log03,log04,log05,log06,log07
-
-   [handlers]
-   keys=hand01,hand02,hand03,hand04,hand05,hand06,hand07,hand08,hand09
-
-   [formatters]
-   keys=form01,form02,form03,form04,form05,form06,form07,form08,form09
-
-The root logger must specify a level and a list of handlers. An example of a
-root logger section is given below. ::
-
-   [logger_root]
-   level=NOTSET
-   handlers=hand01
-
-The ``level`` entry can be one of ``DEBUG, INFO, WARNING, ERROR, CRITICAL`` or
-``NOTSET``. For the root logger only, ``NOTSET`` means that all messages will be
-logged. Level values are :func:`eval`\ uated in the context of the ``logging``
-package's namespace.
-
-The ``handlers`` entry is a comma-separated list of handler names, which must
-appear in the ``[handlers]`` section. These names must appear in the
-``[handlers]`` section and have corresponding sections in the configuration
-file.
-
-For loggers other than the root logger, some additional information is required.
-This is illustrated by the following example. ::
-
-   [logger_parser]
-   level=DEBUG
-   handlers=hand01
-   propagate=1
-   qualname=compiler.parser
-
-The ``level`` and ``handlers`` entries are interpreted as for the root logger,
-except that if a non-root logger's level is specified as ``NOTSET``, the system
-consults loggers higher up the hierarchy to determine the effective level of the
-logger. The ``propagate`` entry is set to 1 to indicate that messages must
-propagate to handlers higher up the logger hierarchy from this logger, or 0 to
-indicate that messages are **not** propagated to handlers up the hierarchy. The
-``qualname`` entry is the hierarchical channel name of the logger, that is to
-say the name used by the application to get the logger.
-
-Sections which specify handler configuration are exemplified by the following.
-::
-
-   [handler_hand01]
-   class=StreamHandler
-   level=NOTSET
-   formatter=form01
-   args=(sys.stdout,)
-
-The ``class`` entry indicates the handler's class (as determined by :func:`eval`
-in the ``logging`` package's namespace). The ``level`` is interpreted as for
-loggers, and ``NOTSET`` is taken to mean "log everything".
-
-The ``formatter`` entry indicates the key name of the formatter for this
-handler. If blank, a default formatter (``logging._defaultFormatter``) is used.
-If a name is specified, it must appear in the ``[formatters]`` section and have
-a corresponding section in the configuration file.
-
-The ``args`` entry, when :func:`eval`\ uated in the context of the ``logging``
-package's namespace, is the list of arguments to the constructor for the handler
-class. Refer to the constructors for the relevant handlers, or to the examples
-below, to see how typical entries are constructed. ::
-
-   [handler_hand02]
-   class=FileHandler
-   level=DEBUG
-   formatter=form02
-   args=('python.log', 'w')
-
-   [handler_hand03]
-   class=handlers.SocketHandler
-   level=INFO
-   formatter=form03
-   args=('localhost', handlers.DEFAULT_TCP_LOGGING_PORT)
-
-   [handler_hand04]
-   class=handlers.DatagramHandler
-   level=WARN
-   formatter=form04
-   args=('localhost', handlers.DEFAULT_UDP_LOGGING_PORT)
-
-   [handler_hand05]
-   class=handlers.SysLogHandler
-   level=ERROR
-   formatter=form05
-   args=(('localhost', handlers.SYSLOG_UDP_PORT), handlers.SysLogHandler.LOG_USER)
-
-   [handler_hand06]
-   class=handlers.NTEventLogHandler
-   level=CRITICAL
-   formatter=form06
-   args=('Python Application', '', 'Application')
-
-   [handler_hand07]
-   class=handlers.SMTPHandler
-   level=WARN
-   formatter=form07
-   args=('localhost', 'from@abc', ['user1@abc', 'user2@xyz'], 'Logger Subject')
-
-   [handler_hand08]
-   class=handlers.MemoryHandler
-   level=NOTSET
-   formatter=form08
-   target=
-   args=(10, ERROR)
-
-   [handler_hand09]
-   class=handlers.HTTPHandler
-   level=NOTSET
-   formatter=form09
-   args=('localhost:9022', '/log', 'GET')
-
-Sections which specify formatter configuration are typified by the following. ::
-
-   [formatter_form01]
-   format=F1 %(asctime)s %(levelname)s %(message)s
-   datefmt=
-   class=logging.Formatter
-
-The ``format`` entry is the overall format string, and the ``datefmt`` entry is
-the :func:`strftime`\ -compatible date/time format string.  If empty, the
-package substitutes ISO8601 format date/times, which is almost equivalent to
-specifying the date format string ``"%Y-%m-%d %H:%M:%S"``.  The ISO8601 format
-also specifies milliseconds, which are appended to the result of using the above
-format string, with a comma separator.  An example time in ISO8601 format is
-``2003-01-23 00:29:50,411``.
-
-The ``class`` entry is optional.  It indicates the name of the formatter's class
-(as a dotted module and class name.)  This option is useful for instantiating a
-:class:`Formatter` subclass.  Subclasses of :class:`Formatter` can present
-exception tracebacks in an expanded or condensed format.

-Configuration server example
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Here is an example of a module using the logging configuration server::
-
-    import logging
-    import logging.config
-    import time
-    import os
-
-    # read initial config file
-    logging.config.fileConfig("logging.conf")
-
-    # create and start listener on port 9999
-    t = logging.config.listen(9999)
-    t.start()
-
-    logger = logging.getLogger("simpleExample")
-
-    try:
-        # loop through logging calls to see the difference
-        # new configurations make, until Ctrl+C is pressed
-        while True:
-            logger.debug("debug message")
-            logger.info("info message")
-            logger.warn("warn message")
-            logger.error("error message")
-            logger.critical("critical message")
-            time.sleep(5)
-    except KeyboardInterrupt:
-        # cleanup
-        logging.config.stopListening()
-        t.join()
-
-And here is a script that takes a filename and sends that file to the server,
-properly preceded with the binary-encoded length, as the new logging
-configuration::
-
-    #!/usr/bin/env python
-    import socket, sys, struct
-
-    data_to_send = open(sys.argv[1], "r").read()
-
-    HOST = 'localhost'
-    PORT = 9999
-    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
-    print("connecting...")
-    s.connect((HOST, PORT))
-    print("sending config...")
-    s.send(struct.pack(">L", len(data_to_send)))
-    s.send(data_to_send)
-    s.close()
-    print("complete")
-

--------------
+   The third optional keyword argument is *extra* which can be used to pass a
+   dictionary which is used to populate the __dict__ of the LogRecord created for
+   the logging event with user-defined attributes. These custom attributes can then
+   be used as you like. For example, they could be incorporated into logged
+   messages. For example::
 
-Multiple handlers and formatters
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Loggers are plain Python objects.  The :func:`addHandler` method has no minimum
-or maximum quota for the number of handlers you may add.  Sometimes it will be
-beneficial for an application to log all messages of all severities to a text
-file while simultaneously logging errors or above to the console.  To set this
-up, simply configure the appropriate handlers.  The logging calls in the
-application code will remain unchanged.  Here is a slight modification to the
-previous simple module-based configuration example::
-
-    import logging
-
-    logger = logging.getLogger("simple_example")
-    logger.setLevel(logging.DEBUG)
-    # create file handler which logs even debug messages
-    fh = logging.FileHandler("spam.log")
-    fh.setLevel(logging.DEBUG)
-    # create console handler with a higher log level
-    ch = logging.StreamHandler()
-    ch.setLevel(logging.ERROR)
-    # create formatter and add it to the handlers
-    formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
-    ch.setFormatter(formatter)
-    fh.setFormatter(formatter)
-    # add the handlers to logger
-    logger.addHandler(ch)
-    logger.addHandler(fh)
-
-    # "application" code
-    logger.debug("debug message")
-    logger.info("info message")
-    logger.warn("warn message")
-    logger.error("error message")
-    logger.critical("critical message")
-
-Notice that the "application" code does not care about multiple handlers.  All
-that changed was the addition and configuration of a new handler named *fh*.
-
-The ability to create new handlers with higher- or lower-severity filters can be
-very helpful when writing and testing an application.  Instead of using many
-``print`` statements for debugging, use ``logger.debug``: Unlike the print
-statements, which you will have to delete or comment out later, the logger.debug
-statements can remain intact in the source code and remain dormant until you
-need them again.  At that time, the only change that needs to happen is to
-modify the severity level of the logger and/or handler to debug.
-
-
-Using logging in multiple modules
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-It was mentioned above that multiple calls to
-``logging.getLogger('someLogger')`` return a reference to the same logger
-object.  This is true not only within the same module, but also across modules
-as long as it is in the same Python interpreter process.  It is true for
-references to the same object; additionally, application code can define and
-configure a parent logger in one module and create (but not configure) a child
-logger in a separate module, and all logger calls to the child will pass up to
-the parent.  Here is a main module::
-
-    import logging
-    import auxiliary_module
-
-    # create logger with "spam_application"
-    logger = logging.getLogger("spam_application")
-    logger.setLevel(logging.DEBUG)
-    # create file handler which logs even debug messages
-    fh = logging.FileHandler("spam.log")
-    fh.setLevel(logging.DEBUG)
-    # create console handler with a higher log level
-    ch = logging.StreamHandler()
-    ch.setLevel(logging.ERROR)
-    # create formatter and add it to the handlers
-    formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
-    fh.setFormatter(formatter)
-    ch.setFormatter(formatter)
-    # add the handlers to the logger
-    logger.addHandler(fh)
-    logger.addHandler(ch)
-
-    logger.info("creating an instance of auxiliary_module.Auxiliary")
-    a = auxiliary_module.Auxiliary()
-    logger.info("created an instance of auxiliary_module.Auxiliary")
-    logger.info("calling auxiliary_module.Auxiliary.do_something")
-    a.do_something()
-    logger.info("finished auxiliary_module.Auxiliary.do_something")
-    logger.info("calling auxiliary_module.some_function()")
-    auxiliary_module.some_function()
-    logger.info("done with auxiliary_module.some_function()")
-
-Here is the auxiliary module::
-
-    import logging
-
-    # create logger
-    module_logger = logging.getLogger("spam_application.auxiliary")
-
-    class Auxiliary:
-        def __init__(self):
-            self.logger = logging.getLogger("spam_application.auxiliary.Auxiliary")
-            self.logger.info("creating an instance of Auxiliary")
-        def do_something(self):
-            self.logger.info("doing something")
-            a = 1 + 1
-            self.logger.info("done doing something")
-
-    def some_function():
-        module_logger.info("received a call to \"some_function\"")
-
-The output looks like this::
-
-    2005-03-23 23:47:11,663 - spam_application - INFO -
-       creating an instance of auxiliary_module.Auxiliary
-    2005-03-23 23:47:11,665 - spam_application.auxiliary.Auxiliary - INFO -

-    2005-03-23 23:47:11,668 - spam_application - INFO -

-    2005-03-23 23:47:11,670 - spam_application - INFO -
-       finished auxiliary_module.Auxiliary.do_something
-    2005-03-23 23:47:11,671 - spam_application - INFO -
-       calling auxiliary_module.some_function()
-    2005-03-23 23:47:11,672 - spam_application.auxiliary - INFO -
-       received a call to "some_function"
-    2005-03-23 23:47:11,673 - spam_application - INFO -
-       done with auxiliary_module.some_function()
+      FORMAT = '%(asctime)-15s %(clientip)s %(user)-8s %(message)s'
+      logging.basicConfig(format=FORMAT)
+      d = {'clientip': '192.168.0.1', 'user': 'fbloggs'}
+      logging.warning('Protocol problem: %s', 'connection reset', extra=d)
+
+   would print something like::
+
+      2006-02-08 22:20:02,165 192.168.0.1 fbloggs  Protocol problem: connection reset
+
+   The keys in the dictionary passed in *extra* should not clash with the keys used
+   by the logging system. (See the :class:`Formatter` documentation for more
+   information on which keys are used by the logging system.)
+
+   If you choose to use these attributes in logged messages, you need to exercise
+   some care. In the above example, for instance, the :class:`Formatter` has been
+   set up with a format string which expects 'clientip' and 'user' in the attribute
+   dictionary of the LogRecord. If these are missing, the message will not be
+   logged because a string formatting exception will occur. So in this case, you
+   always need to pass the *extra* dictionary with these keys.
+
+   While this might be annoying, this feature is intended for use in specialized
+   circumstances, such as multi-threaded servers where the same code executes in
+   many contexts, and interesting conditions which arise are dependent on this
+   context (such as remote client IP address and authenticated user name, in the
+   above example). In such circumstances, it is likely that specialized
+   :class:`Formatter`\ s would be used with particular :class:`Handler`\ s.
+
+   .. versionadded:: 3.2
+      The *stack_info* parameter was added.
+
+.. function:: info(msg, *args, **kwargs)
+
+   Logs a message with level :const:`INFO` on the root logger. The arguments are
+   interpreted as for :func:`debug`.
+
+
+.. function:: warning(msg, *args, **kwargs)
+
+   Logs a message with level :const:`WARNING` on the root logger. The arguments are
+   interpreted as for :func:`debug`.
+
+
+.. function:: error(msg, *args, **kwargs)
+
+   Logs a message with level :const:`ERROR` on the root logger. The arguments are
+   interpreted as for :func:`debug`.
+
+
+.. function:: critical(msg, *args, **kwargs)
+
+   Logs a message with level :const:`CRITICAL` on the root logger. The arguments
+   are interpreted as for :func:`debug`.
+
+
+.. function:: exception(msg, *args)
+
+   Logs a message with level :const:`ERROR` on the root logger. The arguments are
+   interpreted as for :func:`debug`. Exception info is added to the logging
+   message. This function should only be called from an exception handler.
+
+.. function:: log(level, msg, *args, **kwargs)
+
+   Logs a message with level *level* on the root logger. The other arguments are
+   interpreted as for :func:`debug`.
+
+   PLEASE NOTE: The above module-level functions which delegate to the root
+   logger should *not* be used in threads, in versions of Python earlier than
+   2.7.1 and 3.2, unless at least one handler has been added to the root
+   logger *before* the threads are started. These convenience functions call
+   :func:`basicConfig` to ensure that at least one handler is available; in
+   earlier versions of Python, this can (under rare circumstances) lead to
+   handlers being added multiple times to the root logger, which can in turn
+   lead to multiple messages for the same event.
+
+.. function:: disable(lvl)
+
+   Provides an overriding level *lvl* for all loggers which takes precedence over
+   the logger's own level. When the need arises to temporarily throttle logging
+   output down across the whole application, this function can be useful. Its
+   effect is to disable all logging calls of severity *lvl* and below, so that
+   if you call it with a value of INFO, then all INFO and DEBUG events would be
+   discarded, whereas those of severity WARNING and above would be processed
+   according to the logger's effective level.
+
+
+.. function:: addLevelName(lvl, levelName)
+
+   Associates level *lvl* with text *levelName* in an internal dictionary, which is
+   used to map numeric levels to a textual representation, for example when a
+   :class:`Formatter` formats a message. This function can also be used to define
+   your own levels. The only constraints are that all levels used must be
+   registered using this function, levels should be positive integers and they
+   should increase in increasing order of severity.
+
+   NOTE: If you are thinking of defining your own levels, please see the section
+   on :ref:`custom-levels`.
+
+.. function:: getLevelName(lvl)
+
+   Returns the textual representation of logging level *lvl*. If the level is one
+   of the predefined levels :const:`CRITICAL`, :const:`ERROR`, :const:`WARNING`,
+   :const:`INFO` or :const:`DEBUG` then you get the corresponding string. If you
+   have associated levels with names using :func:`addLevelName` then the name you
+   have associated with *lvl* is returned. If a numeric value corresponding to one
+   of the defined levels is passed in, the corresponding string representation is
+   returned. Otherwise, the string 'Level %s' % lvl is returned.
+
+
+.. function:: makeLogRecord(attrdict)
+
+   Creates and returns a new :class:`LogRecord` instance whose attributes are
+   defined by *attrdict*. This function is useful for taking a pickled
+   :class:`LogRecord` attribute dictionary, sent over a socket, and reconstituting
+   it as a :class:`LogRecord` instance at the receiving end.
+
+
+.. function:: basicConfig(**kwargs)
+
+   Does basic configuration for the logging system by creating a
+   :class:`StreamHandler` with a default :class:`Formatter` and adding it to the
+   root logger. The functions :func:`debug`, :func:`info`, :func:`warning`,
+   :func:`error` and :func:`critical` will call :func:`basicConfig` automatically
+   if no handlers are defined for the root logger.
+
+   This function does nothing if the root logger already has handlers
+   configured for it.
+
+   PLEASE NOTE: This function should be called from the main thread
+   before other threads are started. In versions of Python prior to
+   2.7.1 and 3.2, if this function is called from multiple threads,
+   it is possible (in rare circumstances) that a handler will be added
+   to the root logger more than once, leading to unexpected results
+   such as messages being duplicated in the log.
+
+   The following keyword arguments are supported.
+
+   +--------------+---------------------------------------------+
+   | Format       | Description                                 |
+   +==============+=============================================+
+   | ``filename`` | Specifies that a FileHandler be created,    |
+   |              | using the specified filename, rather than a |
+   |              | StreamHandler.                              |
+   +--------------+---------------------------------------------+
+   | ``filemode`` | Specifies the mode to open the file, if     |
+   |              | filename is specified (if filemode is       |
+   |              | unspecified, it defaults to 'a').           |
+   +--------------+---------------------------------------------+
+   | ``format``   | Use the specified format string for the     |
+   |              | handler.                                    |
+   +--------------+---------------------------------------------+
+   | ``datefmt``  | Use the specified date/time format.         |
+   +--------------+---------------------------------------------+
+   | ``style``    | If ``format`` is specified, use this style  |
+   |              | for the format string. One of '%', '{' or   |
+   |              | '$' for %-formatting, :meth:`str.format` or |
+   |              | :class:`string.Template` respectively, and  |
+   |              | defaulting to '%' if not specified.         |
+   +--------------+---------------------------------------------+
+   | ``level``    | Set the root logger level to the specified  |
+   |              | level.                                      |
+   +--------------+---------------------------------------------+
+   | ``stream``   | Use the specified stream to initialize the  |
+   |              | StreamHandler. Note that this argument is   |
+   |              | incompatible with 'filename' - if both are  |
+   |              | present, 'stream' is ignored.               |
+   +--------------+---------------------------------------------+
+
+   .. versionchanged:: 3.2
+      The ``style`` argument was added.
+
+
+.. function:: shutdown()
+
+   Informs the logging system to perform an orderly shutdown by flushing and
+   closing all handlers. This should be called at application exit and no
+   further use of the logging system should be made after this call.
+
+
+.. function:: setLoggerClass(klass)
+
+   Tells the logging system to use the class *klass* when instantiating a logger.
+   The class should define :meth:`__init__` such that only a name argument is
+   required, and the :meth:`__init__` should call :meth:`Logger.__init__`. This
+   function is typically called before any loggers are instantiated by applications
+   which need to use custom logger behavior.
+
+
+.. function:: setLogRecordFactory(factory)
+
+   Set a callable which is used to create a :class:`LogRecord`.
+
+   :param factory: The factory callable to be used to instantiate a log record.
+
+   .. versionadded:: 3.2
+      This function has been provided, along with :func:`getLogRecordFactory`, to
+      allow developers more control over how the :class:`LogRecord` representing
+      a logging event is constructed.
+
+   The factory has the following signature:
+
+   ``factory(name, level, fn, lno, msg, args, exc_info, func=None, sinfo=None, **kwargs)``
+
+      :name: The logger name.
+      :level: The logging level (numeric).
+      :fn: The full pathname of the file where the logging call was made.
+      :lno: The line number in the file where the logging call was made.
+      :msg: The logging message.
+      :args: The arguments for the logging message.
+      :exc_info: An exception tuple, or None.
+      :func: The name of the function or method which invoked the logging
+             call.
+      :sinfo: A stack traceback such as is provided by
+              :func:`traceback.print_stack`, showing the call hierarchy.
+      :kwargs: Additional keyword arguments.
+
+
+Integration with the warnings module
+------------------------------------
+
+The :func:`captureWarnings` function can be used to integrate :mod:`logging`
+with the :mod:`warnings` module.
+
+.. function:: captureWarnings(capture)
+
+   This function is used to turn the capture of warnings by logging on and
+   off.
+
+   If *capture* is ``True``, warnings issued by the :mod:`warnings` module will
+   be redirected to the logging system. Specifically, a warning will be
+   formatted using :func:`warnings.formatwarning` and the resulting string
+   logged to a logger named 'py.warnings' with a severity of `WARNING`.
+
+   If *capture* is ``False``, the redirection of warnings to the logging system
+   will stop, and warnings will be redirected to their original destinations
+   (i.e. those in effect before `captureWarnings(True)` was called).

+
+   Return a pair ``(response, overviews)``.  *overviews* is a list of
+   ``(article_number, overview)`` tuples, one for each article selected
+   by *message_spec*.  Each *overview* is a dictionary with the same number
+   of items, but this number depends on the server.  These items are either
+   message headers (the key is then the lower-cased header name) or metadata
+   items (the key is then the metadata name prepended with ``":"``).  The
+   following items are guaranteed to be present by the NNTP specification:
+
+   * the ``subject``, ``from``, ``date``, ``message-id`` and ``references``
+     headers
+   * the ``:bytes`` metadata: the number of bytes in the entire raw article
+     (including headers and body)
+   * the ``:lines`` metadata: the number of lines in the article body
+
+   The value of each item is either a string, or :const:`None` if not present.
+
+   It is advisable to use the :func:`decode_header` function on header

+Inplace Operators
+=================
+
+Many operations have an "in-place" version.  Listed below are functions
+providing a more primitive access to in-place operators than the usual syntax
+does; for example, the :term:`statement` ``x += y`` is equivalent to
+``x = operator.iadd(x, y)``.  Another way to put it is to say that
+``z = operator.iadd(x, y)`` is equivalent to the compound statement
+``z = x; z += y``.
+
+In those examples, note that when an in-place method is called, the computation
+and assignment are performed in two separate steps.  The in-place functions
+listed below only do the first step, calling the in-place method.  The second
+step, assignment, is not handled.
+
+For immutable targets such as strings, numbers, and tuples, the updated
+value is computed, but not assigned back to the input variable:
+
+>>> a = 'hello'
+>>> iadd(a, ' world')
+'hello world'
+>>> a
+'hello'
+
+For mutable targets such as lists and dictionaries, the inplace method
+will perform the update, so no subsequent assignment is necessary:
+
+>>> s = ['h', 'e', 'l', 'l', 'o']
+>>> iadd(s, [' ', 'w', 'o', 'r', 'l', 'd'])
+['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd']

+.. versionadded:: 3.2
+
+When invoked from the command line, ``python -m pickletools`` will

+
+   ``__package__`` is set to ``__name__.rpartition('.')[0]``.
+
+   A number of alterations are also made to the :mod:`sys` module. Firstly,
+   ``sys.path`` may be altered as described above. ``sys.argv[0]`` is updated
+   with the value of ``file_path`` and ``sys.modules[__name__]`` is updated
+   with a temporary module object for the module being executed. All
+   modifications to items in :mod:`sys` are reverted before the function
+   returns.
+
+   Note that, unlike :func:`run_module`, the alterations made to :mod:`sys`
+   are not optional in this function as these adjustments are essential to
+   allowing the execution of sys.path entries. As the thread-safety
+   limitations still apply, use of this function in threaded code should be

+   CA certificates in PEM format. See the discussion of
+   :ref:`ssl-certificates` for more information about how to arrange the

+
+   Load a set of default "certification authority" (CA) certificates from
+   a filesystem path defined when building the OpenSSL library.  Unfortunately,
+   there's no easy way to know whether this method succeeds: no error is
+   returned if no certificates are to be found.  When the OpenSSL library is
+   provided as part of the operating system, though, it is likely to be
+   configured properly.
+
+.. method:: SSLContext.set_ciphers(ciphers)
+
+   Set the available ciphers for sockets created with this context.
+   It should be a string in the `OpenSSL cipher list format
+   <http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT>`_.
+   If no cipher can be selected (because compile-time options or other
+   configuration forbids use of all the specified ciphers), an
+   :class:`SSLError` will be raised.
+
+   .. note::
+      when connected, the :meth:`SSLSocket.cipher` method of SSL sockets will
+      give the currently selected cipher.
+
+.. method:: SSLContext.wrap_socket(sock, server_side=False, \
+      do_handshake_on_connect=True, suppress_ragged_eofs=True, \
+      server_hostname=None)
+
+   Wrap an existing Python socket *sock* and return an :class:`SSLSocket`
+   object.  The SSL socket is tied to the context, its settings and
+   certificates.  The parameters *server_side*, *do_handshake_on_connect*
+   and *suppress_ragged_eofs* have the same meaning as in the top-level
+   :func:`wrap_socket` function.
+
+   On client connections, the optional parameter *server_hostname* specifies
+   the hostname of the service which we are connecting to.  This allows a
+   single server to host multiple SSL-based services with distinct certificates,
+   quite similarly to HTTP virtual hosts.  Specifying *server_hostname*
+   will raise a :exc:`ValueError` if the OpenSSL library doesn't have support
+   for it (that is, if :data:`HAS_SNI` is :const:`False`).  Specifying
+   *server_hostname* will also raise a :exc:`ValueError` if *server_side*
+   is true.
+
+.. method:: SSLContext.session_stats()
+
+   Get statistics about the SSL sessions created or managed by this context.
+   A dictionary is returned which maps the names of each `piece of information
+   <http://www.openssl.org/docs/ssl/SSL_CTX_sess_number.html>`_ to their
+   numeric values.  For example, here is the total number of hits and misses
+   in the session cache since the context was created::
+
+      >>> stats = context.session_stats()
+      >>> stats['hits'], stats['misses']
+      (0, 0)
+
+.. attribute:: SSLContext.options
+
+   An integer representing the set of SSL options enabled on this context.
+   The default value is :data:`OP_ALL`, but you can specify other options
+   such as :data:`OP_NO_SSLv2` by ORing them together.
+
+   .. note::
+      With versions of OpenSSL older than 0.9.8m, it is only possible
+      to set options, not to clear them.  Attempting to clear an option
+      (by resetting the corresponding bits) will raise a ``ValueError``.
+
+.. attribute:: SSLContext.protocol
+
+   The protocol version chosen when constructing the context.  This attribute
+   is read-only.
+
+.. attribute:: SSLContext.verify_mode
+
+   Whether to try to verify other peers' certificates and how to behave
+   if verification fails.  This attribute must be one of
+   :data:`CERT_NONE`, :data:`CERT_OPTIONAL` or :data:`CERT_REQUIRED`.

+.. _ssl-security:
+
+Security considerations
+-----------------------
+
+Verifying certificates
+^^^^^^^^^^^^^^^^^^^^^^
+
+:const:`CERT_NONE` is the default.  Since it does not authenticate the other
+peer, it can be insecure, especially in client mode where most of time you
+would like to ensure the authenticity of the server you're talking to.
+Therefore, when in client mode, it is highly recommended to use
+:const:`CERT_REQUIRED`.  However, it is in itself not sufficient; you also
+have to check that the server certificate, which can be obtained by calling
+:meth:`SSLSocket.getpeercert`, matches the desired service.  For many
+protocols and applications, the service can be identified by the hostname;
+in this case, the :func:`match_hostname` function can be used.
+
+In server mode, if you want to authenticate your clients using the SSL layer
+(rather than using a higher-level authentication mechanism), you'll also have
+to specify :const:`CERT_REQUIRED` and similarly check the client certificate.
+
+   .. note::
+
+      In client mode, :const:`CERT_OPTIONAL` and :const:`CERT_REQUIRED` are
+      equivalent unless anonymous ciphers are enabled (they are disabled
+      by default).
+
+Protocol versions
+^^^^^^^^^^^^^^^^^
+
+SSL version 2 is considered insecure and is therefore dangerous to use.  If
+you want maximum compatibility between clients and servers, it is recommended
+to use :const:`PROTOCOL_SSLv23` as the protocol version and then disable
+SSLv2 explicitly using the :data:`SSLContext.options` attribute::
+
+   context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
+   context.options |= ssl.OP_NO_SSLv2
+
+The SSL context created above will allow SSLv3 and TLSv1 connections, but
+not SSLv2.

+Hashing of numeric types
+------------------------
+
+For numbers ``x`` and ``y``, possibly of different types, it's a requirement
+that ``hash(x) == hash(y)`` whenever ``x == y`` (see the :meth:`__hash__`
+method documentation for more details).  For ease of implementation and
+efficiency across a variety of numeric types (including :class:`int`,
+:class:`float`, :class:`decimal.Decimal` and :class:`fractions.Fraction`)
+Python's hash for numeric types is based on a single mathematical function
+that's defined for any rational number, and hence applies to all instances of
+:class:`int` and :class:`fraction.Fraction`, and all finite instances of
+:class:`float` and :class:`decimal.Decimal`.  Essentially, this function is
+given by reduction modulo ``P`` for a fixed prime ``P``.  The value of ``P`` is
+made available to Python as the :attr:`modulus` attribute of
+:data:`sys.hash_info`.
+
+.. impl-detail::
+
+   Currently, the prime used is ``P = 2**31 - 1`` on machines with 32-bit C
+   longs and ``P = 2**61 - 1`` on machines with 64-bit C longs.
+
+Here are the rules in detail:
+
+ - If ``x = m / n`` is a nonnegative rational number and ``n`` is not divisible
+   by ``P``, define ``hash(x)`` as ``m * invmod(n, P) % P``, where ``invmod(n,
+   P)`` gives the inverse of ``n`` modulo ``P``.
+
+ - If ``x = m / n`` is a nonnegative rational number and ``n`` is
+   divisible by ``P`` (but ``m`` is not) then ``n`` has no inverse
+   modulo ``P`` and the rule above doesn't apply; in this case define
+   ``hash(x)`` to be the constant value ``sys.hash_info.inf``.
+
+ - If ``x = m / n`` is a negative rational number define ``hash(x)``
+   as ``-hash(-x)``.  If the resulting hash is ``-1``, replace it with
+   ``-2``.
+
+ - The particular values ``sys.hash_info.inf``, ``-sys.hash_info.inf``
+   and ``sys.hash_info.nan`` are used as hash values for positive
+   infinity, negative infinity, or nans (respectively).  (All hashable
+   nans have the same hash value.)
+
+ - For a :class:`complex` number ``z``, the hash values of the real
+   and imaginary parts are combined by computing ``hash(z.real) +
+   sys.hash_info.imag * hash(z.imag)``, reduced modulo
+   ``2**sys.hash_info.width`` so that it lies in
+   ``range(-2**(sys.hash_info.width - 1), 2**(sys.hash_info.width -
+   1))``.  Again, if the result is ``-1``, it's replaced with ``-2``.
+
+
+To clarify the above rules, here's some example Python code,
+equivalent to the builtin hash, for computing the hash of a rational
+number, :class:`float`, or :class:`complex`::
+
+
+   import sys, math
+
+   def hash_fraction(m, n):
+       """Compute the hash of a rational number m / n.
+
+       Assumes m and n are integers, with n positive.
+       Equivalent to hash(fractions.Fraction(m, n)).
+
+       """
+       P = sys.hash_info.modulus
+       # Remove common factors of P.  (Unnecessary if m and n already coprime.)
+       while m % P == n % P == 0:
+           m, n = m // P, n // P
+
+       if n % P == 0:
+           hash_ = sys.hash_info.inf
+       else:
+           # Fermat's Little Theorem: pow(n, P-1, P) is 1, so
+           # pow(n, P-2, P) gives the inverse of n modulo P.
+           hash_ = (abs(m) % P) * pow(n, P - 2, P) % P
+       if m < 0:
+           hash_ = -hash_

+           hash_ = -2

+=========================================================================

+
+**Source code:** :source:`Lib/sysconfig.py`
+
+.. versionadded:: 3.2
+
+--------------
+
+The :mod:`sysconfig` module provides access to Python's configuration
+information like the list of installation paths and the configuration variables
+relevant for the current platform.
+
+Configuration variables
+-----------------------
+
+A Python distribution contains a :file:`Makefile` and a :file:`pyconfig.h`
+header file that are necessary to build both the Python binary itself and
+third-party C extensions compiled using :mod:`distutils`.
+
+:mod:`sysconfig` puts all variables found in these files in a dictionary that
+can be accessed using :func:`get_config_vars` or :func:`get_config_var`.
+
+Notice that on Windows, it's a much smaller set.
+
+.. function:: get_config_vars(\*args)
+
+   With no arguments, return a dictionary of all configuration variables
+   relevant for the current platform.
+
+   With arguments, return a list of values that result from looking up each
+   argument in the configuration variable dictionary.
+
+   For each argument, if the value is not found, return ``None``.
+
+
+.. function:: get_config_var(name)
+
+   Return the value of a single variable *name*. Equivalent to
+   ``get_config_vars().get(name)``.
+
+   If *name* is not found, return ``None``.
+
+Example of usage::
+
+   >>> import sysconfig
+   >>> sysconfig.get_config_var('Py_ENABLE_SHARED')
+   0
+   >>> sysconfig.get_config_var('LIBDIR')
+   '/usr/local/lib'
+   >>> sysconfig.get_config_vars('AR', 'CXX')
+   ['ar', 'g++']
+
+
+Installation paths
+------------------
+
+Python uses an installation scheme that differs depending on the platform and on
+the installation options.  These schemes are stored in :mod:`sysconfig` under
+unique identifiers based on the value returned by :const:`os.name`.
+
+Every new component that is installed using :mod:`distutils` or a
+Distutils-based system will follow the same scheme to copy its file in the right
+places.
+
+Python currently supports seven schemes:
+
+- *posix_prefix*: scheme for Posix platforms like Linux or Mac OS X.  This is
+  the default scheme used when Python or a component is installed.
+- *posix_home*: scheme for Posix platforms used when a *home* option is used
+  upon installation.  This scheme is used when a component is installed through
+  Distutils with a specific home prefix.
+- *posix_user*: scheme for Posix platforms used when a component is installed
+  through Distutils and the *user* option is used.  This scheme defines paths
+  located under the user home directory.
+- *nt*: scheme for NT platforms like Windows.
+- *nt_user*: scheme for NT platforms, when the *user* option is used.
+- *os2*: scheme for OS/2 platforms.
+- *os2_home*: scheme for OS/2 patforms, when the *user* option is used.
+
+Each scheme is itself composed of a series of paths and each path has a unique
+identifier.  Python currently uses eight paths:
+
+- *stdlib*: directory containing the standard Python library files that are not
+  platform-specific.
+- *platstdlib*: directory containing the standard Python library files that are
+  platform-specific.
+- *platlib*: directory for site-specific, platform-specific files.
+- *purelib*: directory for site-specific, non-platform-specific files.
+- *include*: directory for non-platform-specific header files.
+- *platinclude*: directory for platform-specific header files.
+- *scripts*: directory for script files.
+- *data*: directory for data files.
+
+:mod:`sysconfig` provides some functions to determine these paths.
+
+.. function:: get_scheme_names()
+
+   Return a tuple containing all schemes currently supported in
+   :mod:`sysconfig`.
+
+
+.. function:: get_path_names()
+
+   Return a tuple containing all path names currently supported in
+   :mod:`sysconfig`.
+
+
+.. function:: get_path(name, [scheme, [vars, [expand]]])
+
+   Return an installation path corresponding to the path *name*, from the
+   install scheme named *scheme*.
+
+   *name* has to be a value from the list returned by :func:`get_path_names`.
+
+   :mod:`sysconfig` stores installation paths corresponding to each path name,
+   for each platform, with variables to be expanded.  For instance the *stdlib*
+   path for the *nt* scheme is: ``{base}/Lib``.
+
+   :func:`get_path` will use the variables returned by :func:`get_config_vars`
+   to expand the path.  All variables have default values for each platform so
+   one may call this function and get the default value.
+
+   If *scheme* is provided, it must be a value from the list returned by
+   :func:`get_path_names`.  Otherwise, the default scheme for the current
+   platform is used.
+
+   If *vars* is provided, it must be a dictionary of variables that will update
+   the dictionary return by :func:`get_config_vars`.
+
+   If *expand* is set to ``False``, the path will not be expanded using the
+   variables.
+
+   If *name* is not found, return ``None``.
+
+
+.. function:: get_paths([scheme, [vars, [expand]]])
+
+   Return a dictionary containing all installation paths corresponding to an
+   installation scheme. See :func:`get_path` for more information.
+
+   If *scheme* is not provided, will use the default scheme for the current
+   platform.
+
+   If *vars* is provided, it must be a dictionary of variables that will
+   update the dictionary used to expand the paths.
+
+   If *expand* is set to False, the paths will not be expanded.
+
+   If *scheme* is not an existing scheme, :func:`get_paths` will raise a
+   :exc:`KeyError`.
+
+
+Other functions
+---------------
+
+.. function:: get_python_version()
+
+   Return the ``MAJOR.MINOR`` Python version number as a string.  Similar to
+   ``sys.version[:3]``.
+
+
+.. function:: get_platform()
+
+   Return a string that identifies the current platform.
+
+   This is used mainly to distinguish platform-specific build directories and
+   platform-specific built distributions.  Typically includes the OS name and
+   version and the architecture (as supplied by :func:`os.uname`), although the
+   exact information included depends on the OS; e.g. for IRIX the architecture
+   isn't particularly important (IRIX only runs on SGI hardware), but for Linux
+   the kernel version isn't particularly important.
+
+   Examples of returned values:
+
+   - linux-i586
+   - linux-alpha (?)
+   - solaris-2.6-sun4u
+   - irix-5.3
+   - irix64-6.2

+   - macosx-10.6-ppc
+   - macosx-10.4-ppc64

+
+   For other non-POSIX platforms, currently just returns :data:`sys.platform`.

+   *fp* is a file-like object pointing to the :file:`config.h`\-like file.
+
+   A dictionary containing name/value pairs is returned.  If an optional
+   dictionary is passed in as the second argument, it is used instead of a new
+   dictionary, and updated with the values read in the file.
+
+
+.. function:: get_config_h_filename()
+
+   Return the path of :file:`pyconfig.h`.
+
+.. function:: get_makefile_filename()
+

+
+Using :mod:`sysconfig` as a script

+The :mod:`test` package can be run as a script to drive Python's regression

 Running the script by itself automatically starts running all regression
 tests in the :mod:`test` package. It does this by finding all modules in the

-function :func:`test_main` if present. The names of tests to execute may also be

+
+   A convenience wrapper for :func:`warnings.catch_warnings()` that makes it
+   easier to test that a warning was correctly raised.  It is approximately
+   equivalent to calling ``warnings.catch_warnings(record=True)`` with
+   :meth:`warnings.simplefilter` set to ``always`` and with the option to
+   automatically validate the results that are recorded.
+
+   ``check_warnings`` accepts 2-tuples of the form ``("message regexp",
+   WarningCategory)`` as positional arguments. If one or more *filters* are
+   provided, or if the optional keyword argument *quiet* is :const:`False`,
+   it checks to make sure the warnings are as expected:  each specified filter
+   must match at least one of the warnings raised by the enclosed code or the
+   test fails, and if any warnings are raised that do not match any of the
+   specified filters the test fails.  To disable the first of these checks,
+   set *quiet* to :const:`True`.
+
+   If no arguments are specified, it defaults to::
+
+      check_warnings(("", Warning), quiet=True)

+   In this case all warnings are caught and no errors are raised.
 
-   The main difference is that on entry to the context manager, a
-   :class:`WarningRecorder` instance is returned instead of a simple list.
-   The underlying warnings list is available via the recorder object's
-   :attr:`warnings` attribute, while the attributes of the last raised

-   been raised, then the latter attributes will all be :const:`None`.

+   the recorder object (see example below).  If no warning has been raised,
+   then any of the attributes that would otherwise be expected on an object
+   representing a warning will return :const:`None`.

+          exec('assert(False, "Hey!")')
+          warnings.warn(UserWarning("Hide me!"))
+
+   In this case if either warning was not raised, or some other warning was
+   raised, :func:`check_warnings` would raise an error.
+

+Barrier Objects
+---------------
+
+.. versionadded:: 3.2
+
+This class provides a simple synchronization primitive for use by a fixed number
+of threads that need to wait for each other.  Each of the threads tries to pass
+the barrier by calling the :meth:`wait` method and will block until all of the
+threads have made the call.  At this points, the threads are released
+simultanously.
+
+The barrier can be reused any number of times for the same number of threads.
+
+As an example, here is a simple way to synchronize a client and server thread::
+
+   b = Barrier(2, timeout=5)
+
+   def server():
+       start_server()
+       b.wait()
+       while True:
+           connection = accept_connection()
+           process_server_connection(connection)
+
+   def client():
+       b.wait()
+       while True:
+           connection = make_connection()
+           process_client_connection(connection)
+
+
+.. class:: Barrier(parties, action=None, timeout=None)
+
+   Create a barrier object for *parties* number of threads.  An *action*, when
+   provided, is a callable to be called by one of the threads when they are
+   released.  *timeout* is the default timeout value if none is specified for
+   the :meth:`wait` method.
+
+   .. method:: wait(timeout=None)
+
+      Pass the barrier.  When all the threads party to the barrier have called
+      this function, they are all released simultaneously.  If a *timeout* is
+      provided, is is used in preference to any that was supplied to the class
+      constructor.
+
+      The return value is an integer in the range 0 to *parties* -- 1, different
+      for each thread.  This can be used to select a thread to do some special
+      housekeeping, e.g.::
+
+         i = barrier.wait()
+         if i == 0:
+             # Only one thread needs to print this
+             print("passed the barrier")
+
+      If an *action* was provided to the constructor, one of the threads will
+      have called it prior to being released.  Should this call raise an error,
+      the barrier is put into the broken state.
+
+      If the call times out, the barrier is put into the broken state.
+
+      This method may raise a :class:`BrokenBarrierError` exception if the
+      barrier is broken or reset while a thread is waiting.
+
+   .. method:: reset()
+
+      Return the barrier to the default, empty state.  Any threads waiting on it
+      will receive the :class:`BrokenBarrierError` exception.
+
+      Note that using this function may can require some external
+      synchronization if there are other threads whose state is unknown.  If a
+      barrier is broken it may be better to just leave it and create a new one.
+
+   .. method:: abort()
+
+      Put the barrier into a broken state.  This causes any active or future
+      calls to :meth:`wait` to fail with the :class:`BrokenBarrierError`.  Use
+      this for example if one of the needs to abort, to avoid deadlocking the
+      application.
+
+      It may be preferable to simply create the barrier with a sensible
+      *timeout* value to automatically guard against one of the threads going
+      awry.
+
+   .. attribute:: parties

+
+.. program:: unittest
+
+.. cmdoption:: -b, --buffer
+
+   The standard output and standard error streams are buffered during the test
+   run. Output during a passing test is discarded. Output is echoed normally

+
+   Control-C during the test run waits for the current test to end and then
+   reports all the results so far. A second control-C raises the normal

+
+   See `Signal Handling`_ for the functions that provide this functionality.
+
+.. cmdoption:: -f, --failfast
+
+   Stop the test run on the first error or failure.
+
+.. versionadded:: 3.2
+   The command-line options ``-b``, ``-c`` and ``-f`` were added.
+
+The command line can also be used for test discovery, for running all of the

+
+
+.. _unittest-test-discovery:
+
+Test Discovery
+--------------
+
+.. versionadded:: 3.2
+
+Unittest supports simple test discovery. In order to be compatible with test
+discovery, all of the test files must be :ref:`modules <tut-modules>` or
+:ref:`packages <tut-packages>` importable from the top-level directory of
+the project (this means that their filenames must be valid
+:ref:`identifiers <identifiers>`).
+
+Test discovery is implemented in :meth:`TestLoader.discover`, but can also be
+used from the command line. The basic command-line usage is::
+
+   cd project_directory
+   python -m unittest discover
+
+.. note::
+
+   As a shortcut, ``python -m unittest`` is the equivalent of
+   ``python -m unittest discover``. If you want to pass arguments to test
+   discovery the `discover` sub-command must be used explicitly.
+
+The ``discover`` sub-command has the following options:
+
+.. program:: unittest discover
+
+.. cmdoption:: -v, --verbose
+
+   Verbose output
+
+.. cmdoption:: -s directory
+
+   Directory to start discovery ('.' default)
+
+.. cmdoption:: -p pattern
+
+   Pattern to match test files ('test*.py' default)
+
+.. cmdoption:: -t directory
+
+   Top level directory of project (defaults to start directory)
+
+The :option:`-s`, :option:`-p`, and :option:`-t` options can be passed in
+as positional arguments in that order. The following two command lines
+are equivalent::
+
+   python -m unittest discover -s project_directory -p '*_test.py'
+   python -m unittest discover project_directory '*_test.py'
+
+As well as being a path it is possible to pass a package name, for example
+``myproject.subpackage.test``, as the start directory. The package name you
+supply will then be imported and its location on the filesystem will be used
+as the start directory.
+
+.. caution::
+
+    Test discovery loads tests by importing them. Once test discovery has found
+    all the test files from the start directory you specify it turns the paths
+    into package names to import. For example :file:`foo/bar/baz.py` will be
+    imported as ``foo.bar.baz``.
+
+    If you have a package installed globally and attempt test discovery on
+    a different copy of the package then the import *could* happen from the
+    wrong place. If this happens test discovery will warn you and exit.
+
+    If you supply the start directory as a package name rather than a
+    path to a directory then discover assumes that whichever location it
+    imports from is the location you intended, so you will not get the
+    warning.
+
+Test modules and packages can customize test loading and discovery by through
+the `load_tests protocol`_.

+load_tests Protocol
+###################
+
+.. versionadded:: 3.2
+
+Modules or packages can customize how tests are loaded from them during normal
+test runs or test discovery by implementing a function called ``load_tests``.
+
+If a test module defines ``load_tests`` it will be called by
+:meth:`TestLoader.loadTestsFromModule` with the following arguments::
+
+    load_tests(loader, standard_tests, None)
+
+It should return a :class:`TestSuite`.
+
+*loader* is the instance of :class:`TestLoader` doing the loading.
+*standard_tests* are the tests that would be loaded by default from the
+module. It is common for test modules to only want to add or remove tests
+from the standard set of tests.
+The third argument is used when loading packages as part of test discovery.
+
+A typical ``load_tests`` function that loads tests from a specific set of
+:class:`TestCase` classes may look like::
+
+    test_cases = (TestCase1, TestCase2, TestCase3)
+
+    def load_tests(loader, tests, pattern):
+        suite = TestSuite()
+        for test_class in test_cases:
+            tests = loader.loadTestsFromTestCase(test_class)
+            suite.addTests(tests)
+        return suite
+
+If discovery is started, either from the command line or by calling
+:meth:`TestLoader.discover`, with a pattern that matches a package
+name then the package :file:`__init__.py` will be checked for ``load_tests``.
+
+.. note::
+
+   The default pattern is 'test*.py'. This matches all Python files
+   that start with 'test' but *won't* match any test directories.
+
+   A pattern like 'test*' will match test packages as well as
+   modules.
+
+If the package :file:`__init__.py` defines ``load_tests`` then it will be
+called and discovery not continued into the package. ``load_tests``
+is called with the following arguments::
+
+    load_tests(loader, standard_tests, pattern)
+
+This should return a :class:`TestSuite` representing all the tests
+from the package. (``standard_tests`` will only contain tests
+collected from :file:`__init__.py`.)
+
+Because the pattern is passed into ``load_tests`` the package is free to
+continue (and potentially modify) test discovery. A 'do nothing'
+``load_tests`` function for a test package would look like::
+
+    def load_tests(loader, standard_tests, pattern):
+        # top level directory cached on loader instance
+        this_dir = os.path.dirname(__file__)
+        package_tests = loader.discover(start_dir=this_dir, pattern=pattern)
+        standard_tests.addTests(package_tests)
+        return standard_tests
+
+
+Class and Module Fixtures
+-------------------------
+
+Class and module level fixtures are implemented in :class:`TestSuite`. When
+the test suite encounters a test from a new class then :meth:`tearDownClass`
+from the previous class (if there is one) is called, followed by
+:meth:`setUpClass` from the new class.
+
+Similarly if a test is from a different module from the previous test then
+``tearDownModule`` from the previous module is run, followed by
+``setUpModule`` from the new module.
+
+After all the tests have run the final ``tearDownClass`` and
+``tearDownModule`` are run.
+
+Note that shared fixtures do not play well with [potential] features like test
+parallelization and they break test isolation. They should be used with care.
+
+The default ordering of tests created by the unittest test loaders is to group
+all tests from the same modules and classes together. This will lead to
+``setUpClass`` / ``setUpModule`` (etc) being called exactly once per class and
+module. If you randomize the order, so that tests from different modules and
+classes are adjacent to each other, then these shared fixture functions may be
+called multiple times in a single test run.
+
+Shared fixtures are not intended to work with suites with non-standard
+ordering. A ``BaseTestSuite`` still exists for frameworks that don't want to
+support shared fixtures.
+
+If there are any exceptions raised during one of the shared fixture functions
+the test is reported as an error. Because there is no corresponding test
+instance an ``_ErrorHolder`` object (that has the same interface as a
+:class:`TestCase`) is created to represent the error. If you are just using
+the standard unittest test runner then this detail doesn't matter, but if you
+are a framework author it may be relevant.
+
+
+setUpClass and tearDownClass
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+These must be implemented as class methods::
+
+    import unittest
+
+    class Test(unittest.TestCase):
+        @classmethod
+        def setUpClass(cls):
+            cls._connection = createExpensiveConnectionObject()
+
+        @classmethod
+        def tearDownClass(cls):
+            cls._connection.destroy()
+
+If you want the ``setUpClass`` and ``tearDownClass`` on base classes called
+then you must call up to them yourself. The implementations in
+:class:`TestCase` are empty.
+
+If an exception is raised during a ``setUpClass`` then the tests in the class
+are not run and the ``tearDownClass`` is not run. Skipped classes will not
+have ``setUpClass`` or ``tearDownClass`` run. If the exception is a
+``SkipTest`` exception then the class will be reported as having been skipped
+instead of as an error.
+
+
+setUpModule and tearDownModule
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+These should be implemented as functions::
+
+    def setUpModule():
+        createConnection()
+
+    def tearDownModule():
+        closeConnection()
+
+If an exception is raised in a ``setUpModule`` then none of the tests in the
+module will be run and the ``tearDownModule`` will not be run. If the exception is a
+``SkipTest`` exception then the module will be reported as having been skipped
+instead of as an error.
+
+
+Signal Handling
+---------------
+
+.. versionadded:: 3.2
+
+The :option:`-c/--catch <unittest -c>` command-line option to unittest,
+along with the ``catchbreak`` parameter to :func:`unittest.main()`, provide
+more friendly handling of control-C during a test run. With catch break
+behavior enabled control-C will allow the currently running test to complete,
+and the test run will then end and report all the results so far. A second
+control-c will raise a :exc:`KeyboardInterrupt` in the usual way.
+
+The control-c handling signal handler attempts to remain compatible with code or
+tests that install their own :const:`signal.SIGINT` handler. If the ``unittest``
+handler is called but *isn't* the installed :const:`signal.SIGINT` handler,
+i.e. it has been replaced by the system under test and delegated to, then it
+calls the default handler. This will normally be the expected behavior by code
+that replaces an installed handler and delegates to it. For individual tests
+that need ``unittest`` control-c handling disabled the :func:`removeHandler`
+decorator can be used.
+
+There are a few utility functions for framework authors to enable control-c
+handling functionality within test frameworks.
+
+.. function:: installHandler()
+
+   Install the control-c handler. When a :const:`signal.SIGINT` is received
+   (usually in response to the user pressing control-c) all registered results
+   have :meth:`~TestResult.stop` called.
+
+
+.. function:: registerResult(result)
+
+   Register a :class:`TestResult` object for control-c handling. Registering a
+   result stores a weak reference to it, so it doesn't prevent the result from
+   being garbage collected.
+
+   Registering a :class:`TestResult` object has no side-effects if control-c
+   handling is not enabled, so test frameworks can unconditionally register
+   all results they create independently of whether or not handling is enabled.
+
+
+.. function:: removeResult(result)
+
+   Remove a registered result. Once a result has been removed then
+   :meth:`~TestResult.stop` will no longer be called on that result object in
+   response to a control-c.
+
+
+.. function:: removeHandler(function=None)
+
+   When called without arguments this function removes the control-c handler
+   if it has been installed. This function can also be used as a test decorator
+   to temporarily remove the handler whilst the test is being executed::
+
+      @unittest.removeHandler
+      def test_signal_handling(self):
+          ...

+
+.. _parsing-ascii-encoded-bytes:
+
+Parsing ASCII Encoded Bytes
+---------------------------
+
+The URL parsing functions were originally designed to operate on character
+strings only. In practice, it is useful to be able to manipulate properly
+quoted and encoded URLs as sequences of ASCII bytes. Accordingly, the
+URL parsing functions in this module all operate on :class:`bytes` and
+:class:`bytearray` objects in addition to :class:`str` objects.
+
+If :class:`str` data is passed in, the result will also contain only
+:class:`str` data. If :class:`bytes` or :class:`bytearray` data is
+passed in, the result will contain only :class:`bytes` data.
+
+Attempting to mix :class:`str` data with :class:`bytes` or
+:class:`bytearray` in a single function call will result in a
+:exc:`TypeError` being raised, while attempting to pass in non-ASCII
+byte values will trigger :exc:`UnicodeDecodeError`.
+
+To support easier conversion of result objects between :class:`str` and
+:class:`bytes`, all return values from URL parsing functions provide
+either an :meth:`encode` method (when the result contains :class:`str`
+data) or a :meth:`decode` method (when the result contains :class:`bytes`
+data). The signatures of these methods match those of the corresponding
+:class:`str` and :class:`bytes` methods (except that the default encoding
+is ``'ascii'`` rather than ``'utf-8'``). Each produces a value of a
+corresponding type that contains either :class:`bytes` data (for
+:meth:`encode` methods) or :class:`str` data (for
+:meth:`decode` methods).
+
+Applications that need to operate on potentially improperly quoted URLs
+that may contain non-ASCII data will need to do their own decoding from
+bytes to characters before invoking the URL parsing methods.
+
+The behaviour described in this section applies only to the URL parsing
+functions. The URL quoting functions use their own rules when producing
+or consuming byte sequences as detailed in the documentation of the
+individual URL quoting functions.

+
+Structured Parse Results
+------------------------
+
+The result objects from the :func:`urlparse`, :func:`urlsplit`  and
+:func:`urldefrag` functions are subclasses of the :class:`tuple` type.
+These subclasses add the attributes listed in the documentation for
+those functions, the encoding and decoding support described in the
+previous section, as well as an additional method:
+
+.. method:: urllib.parse.SplitResult.geturl()
+
+   Return the re-combined version of the original URL as a string. This may
+   differ from the original URL in that the scheme may be normalized to lower
+   case and empty components may be dropped. Specifically, empty parameters,
+   queries, and fragment identifiers will be removed.
+
+   For :func:`urldefrag` results, only empty fragment identifiers will be removed.
+   For :func:`urlsplit` and :func:`urlparse` results, all noted changes will be
+   made to the URL returned by this method.
+
+   The result of this method remains unchanged if passed back through the original
+   parsing function:
+
+      >>> from urllib.parse import urlsplit
+      >>> url = 'HTTP://www.Python.org/doc/#'
+      >>> r1 = urlsplit(url)
+      >>> r1.geturl()
+      'http://www.Python.org/doc/'

+   :class:`FancyURLopener` subclasses :class:`URLopener` providing default handling
+   for the following HTTP response codes: 301, 302, 303, 307 and 401.  For the 30x
+   response codes listed above, the :mailheader:`Location` header is used to fetch
+   the actual URL.  For 401 response codes (authentication required), basic HTTP
+   authentication is performed.  For the 30x response codes, recursion is bounded
+   by the value of the *maxtries* attribute, which defaults to 10.
+
+   For all other response codes, the method :meth:`http_error_default` is called
+   which you can override in subclasses to handle the error appropriately.
+
+   .. note::
+
+      According to the letter of :rfc:`2616`, 301 and 302 responses to POST requests
+      must not be automatically redirected without confirmation by the user.  In
+      reality, browsers do allow automatic redirection of these responses, changing
+      the POST to a GET, and :mod:`urllib` reproduces this behaviour.
+
+   The parameters to the constructor are the same as those for :class:`URLopener`.
+
+   .. note::
+
+      When performing basic authentication, a :class:`FancyURLopener` instance calls
+      its :meth:`prompt_user_passwd` method.  The default implementation asks the
+      users for the required information on the controlling terminal.  A subclass may
+      override this method to support more appropriate behavior if needed.
+
+   The :class:`FancyURLopener` class offers one additional method that should be
+   overloaded to provide the appropriate behavior:
+
+   .. method:: prompt_user_passwd(host, realm)
+
+      Return information needed to authenticate the user at the given host in the
+      specified security realm.  The return value should be a tuple, ``(user,
+      password)``, which can be used for basic authentication.
+
+      The implementation prompts for this information on the terminal; an application
+      should override this method to use an appropriate interaction model in the local
+      environment.

+Updating Code For New Versions of Python
+----------------------------------------
+
+Warnings that are only of interest to the developer are ignored by default. As
+such you should make sure to test your code with typically ignored warnings
+made visible. You can do this from the command-line by passing :option:`-Wd`
+to the interpreter (this is shorthand for :option:`-W default`).  This enables
+default handling for all warnings, including those that are ignored by default.
+To change what action is taken for encountered warnings you simply change what
+argument is passed to :option:`-W`, e.g. :option:`-W error`. See the
+:option:`-W` flag for more details on what is possible.
+
+To programmatically do the same as :option:`-Wd`, use::
+
+  warnings.simplefilter('default')
+
+Make sure to execute this code as soon as possible. This prevents the
+registering of what warnings have been raised from unexpectedly influencing how
+future warnings are treated.
+
+Having certain warnings ignored by default is done to prevent a user from
+seeing warnings that are only of interest to the developer. As you do not
+necessarily have control over what interpreter a user uses to run their code,
+it is possible that a new version of Python will be released between your
+release cycles.  The new interpreter release could trigger new warnings in your
+code that were not there in an older interpreter, e.g.
+:exc:`DeprecationWarning` for a module that you are using. While you as a
+developer want to be notified that your code is using a deprecated module, to a
+user this information is essentially noise and provides no benefit to them.

+   By default, IIS gives a ``PATH_INFO`` that duplicates the ``SCRIPT_NAME`` at

+
+   IIS can be configured to pass the correct ``PATH_INFO``, but this causes

+
+Numeric handling has been improved in many ways, for both

+other improvements.
+
+Python 2.7 is planned to be the last of the 2.x releases, so we worked
+on making it a good release for the long term.  To help with porting
+to Python 3, several new features from the Python 3.x series have been
+included in 2.7.
+
+This article doesn't attempt to provide a complete specification of
+the new features, but instead provides a convenient overview.  For
+full details, you should refer to the documentation for Python 2.7 at
+http://docs.python.org. If you want to understand the rationale for
+the design and implementation, refer to the PEP for a particular new
+feature or the issue on http://bugs.python.org in which a change was

+
+The Future for Python 2.x
+=========================
+
+Python 2.7 is intended to be the last major release in the 2.x series.
+The Python maintainers are planning to focus their future efforts on
+the Python 3.x series.
+
+This means that 2.7 will remain in place for a long time, running
+production systems that have not been ported to Python 3.x.
+Two consequences of the long-term significance of 2.7 are:
+
+* It's very likely the 2.7 release will have a longer period of
+  maintenance compared to earlier 2.x versions.  Python 2.7 will
+  continue to be maintained while the transition to 3.x continues, and
+  the developers are planning to support Python 2.7 with bug-fix
+  releases beyond the typical two years.
+
+* A policy decision was made to silence warnings only of interest to
+  developers.  :exc:`DeprecationWarning` and its
+  descendants are now ignored unless otherwise requested, preventing
+  users from seeing warnings triggered by an application.  This change
+  was also made in the branch that will become Python 3.2. (Discussed
+  on stdlib-sig and carried out in :issue:`7319`.)
+
+  In previous releases, :exc:`DeprecationWarning` messages were
+  enabled by default, providing Python developers with a clear
+  indication of where their code may break in a future major version
+  of Python.
+
+  However, there are increasingly many users of Python-based
+  applications who are not directly involved in the development of
+  those applications.  :exc:`DeprecationWarning` messages are
+  irrelevant to such users, making them worry about an application
+  that's actually working correctly and burdening application developers
+  with responding to these concerns.
+
+  You can re-enable display of :exc:`DeprecationWarning` messages by
+  running Python with the :option:`-Wdefault` (short form:
+  :option:`-Wd`) switch, or by setting the :envvar:`PYTHONWARNINGS`
+  environment variable to ``"default"`` (or ``"d"``) before running
+  Python.  Python code can also re-enable them
+  by calling ``warnings.simplefilter('default')``.
+
+
+Python 3.1 Features
+=======================
+
+Much as Python 2.6 incorporated features from Python 3.0,
+version 2.7 incorporates some of the new features
+in Python 3.1.  The 2.x series continues to provide tools
+for migrating to the 3.x series.
+
+A partial list of 3.1 features that were backported to 2.7:
+
+* The syntax for set literals (``{1,2,3}`` is a mutable set).
+* Dictionary and set comprehensions (``{ i: i*2 for i in range(3)}``).
+* Multiple context managers in a single :keyword:`with` statement.
+* A new version of the :mod:`io` library, rewritten in C for performance.
+* The ordered-dictionary type described in :ref:`pep-0372`.
+* The new ``","`` format specifier described in :ref:`pep-0378`.
+* The :class:`memoryview` object.
+* A small subset of the :mod:`importlib` module,
+  `described below <#importlib-section>`__.
+* The :func:`repr` of a float ``x`` is shorter in many cases: it's now
+  based on the shortest decimal string that's guaranteed to round back
+  to ``x``.  As in previous versions of Python, it's guaranteed that
+  ``float(repr(x))`` recovers ``x``.
+* Float-to-string and string-to-float conversions are correctly rounded.
+  The :func:`round` function is also now correctly rounded.
+* The :c:type:`PyCapsule` type, used to provide a C API for extension modules.
+* The :c:func:`PyLong_AsLongAndOverflow` C API function.
+
+Other new Python3-mode warnings include:
+
+* :func:`operator.isCallable` and :func:`operator.sequenceIncludes`,
+  which are not supported in 3.x, now trigger warnings.
+* The :option:`-3` switch now automatically
+  enables the :option:`-Qwarn` switch that causes warnings
+  about using classic division with integers and long integers.
+

+.. ========================================================================
+
+.. _pep-0372:
+
+PEP 372: Adding an Ordered Dictionary to collections
+====================================================
+
+Regular Python dictionaries iterate over key/value pairs in arbitrary order.
+Over the years, a number of authors have written alternative implementations
+that remember the order that the keys were originally inserted.  Based on
+the experiences from those implementations, 2.7 introduces a new
+:class:`~collections.OrderedDict` class in the :mod:`collections` module.
+
+The :class:`~collections.OrderedDict` API provides the same interface as regular
+dictionaries but iterates over keys and values in a guaranteed order
+depending on when a key was first inserted::
+
+    >>> from collections import OrderedDict
+    >>> d = OrderedDict([('first', 1),
+    ...                  ('second', 2),
+    ...                  ('third', 3)])
+    >>> d.items()
+    [('first', 1), ('second', 2), ('third', 3)]
+
+If a new entry overwrites an existing entry, the original insertion
+position is left unchanged::
+
+    >>> d['second'] = 4
+    >>> d.items()
+    [('first', 1), ('second', 4), ('third', 3)]
+
+Deleting an entry and reinserting it will move it to the end::
+
+    >>> del d['second']
+    >>> d['second'] = 5
+    >>> d.items()
+    [('first', 1), ('third', 3), ('second', 5)]
+
+The :meth:`~collections.OrderedDict.popitem` method has an optional *last*
+argument that defaults to True.  If *last* is True, the most recently
+added key is returned and removed; if it's False, the
+oldest key is selected::
+
+    >>> od = OrderedDict([(x,0) for x in range(20)])
+    >>> od.popitem()
+    (19, 0)
+    >>> od.popitem()
+    (18, 0)
+    >>> od.popitem(last=False)
+    (0, 0)
+    >>> od.popitem(last=False)
+    (1, 0)
+
+Comparing two ordered dictionaries checks both the keys and values,
+and requires that the insertion order was the same::
+
+    >>> od1 = OrderedDict([('first', 1),
+    ...                    ('second', 2),
+    ...                    ('third', 3)])
+    >>> od2 = OrderedDict([('third', 3),
+    ...                    ('first', 1),
+    ...                    ('second', 2)])
+    >>> od1 == od2
+    False
+    >>> # Move 'third' key to the end
+    >>> del od2['third']; od2['third'] = 3
+    >>> od1 == od2
+    True
+
+Comparing an :class:`~collections.OrderedDict` with a regular dictionary
+ignores the insertion order and just compares the keys and values.
+
+How does the :class:`~collections.OrderedDict` work?  It maintains a
+doubly-linked list of keys, appending new keys to the list as they're inserted.
+A secondary dictionary maps keys to their corresponding list node, so
+deletion doesn't have to traverse the entire linked list and therefore
+remains O(1).
+
+The standard library now supports use of ordered dictionaries in several
+modules.
+
+* The :mod:`ConfigParser` module uses them by default, meaning that
+  configuration files can now be read, modified, and then written back
+  in their original order.
+
+* The :meth:`~collections.somenamedtuple._asdict()` method for
+  :func:`collections.namedtuple` now returns an ordered dictionary with the
+  values appearing in the same order as the underlying tuple indices.
+
+* The :mod:`json` module's :class:`~json.JSONDecoder` class
+  constructor was extended with an *object_pairs_hook* parameter to
+  allow :class:`OrderedDict` instances to be built by the decoder.
+  Support was also added for third-party tools like
+  `PyYAML <http://pyyaml.org/>`_.
+
+.. seealso::
+
+   :pep:`372` - Adding an ordered dictionary to collections
+     PEP written by Armin Ronacher and Raymond Hettinger;
+     implemented by Raymond Hettinger.
+
+.. _pep-0378:
+
+PEP 378: Format Specifier for Thousands Separator
+=================================================
+
+To make program output more readable, it can be useful to add
+separators to large numbers, rendering them as
+18,446,744,073,709,551,616 instead of 18446744073709551616.
+
+The fully general solution for doing this is the :mod:`locale` module,
+which can use different separators ("," in North America, "." in
+Europe) and different grouping sizes, but :mod:`locale` is complicated
+to use and unsuitable for multi-threaded applications where different
+threads are producing output for different locales.
+
+Therefore, a simple comma-grouping mechanism has been added to the
+mini-language used by the :meth:`str.format` method.  When
+formatting a floating-point number, simply include a comma between the
+width and the precision::
+
+   >>> '{:20,.2f}'.format(18446744073709551616.0)
+   '18,446,744,073,709,551,616.00'
+
+When formatting an integer, include the comma after the width:
+
+   >>> '{:20,d}'.format(18446744073709551616)
+   '18,446,744,073,709,551,616'
+
+This mechanism is not adaptable at all; commas are always used as the
+separator and the grouping is always into three-digit groups.  The
+comma-formatting mechanism isn't as general as the :mod:`locale`
+module, but it's easier to use.
+
+.. seealso::
+
+   :pep:`378` - Format Specifier for Thousands Separator
+     PEP written by Raymond Hettinger; implemented by Eric Smith.
+
+PEP 389: The argparse Module for Parsing Command Lines
+======================================================
+
+The :mod:`argparse` module for parsing command-line arguments was
+added as a more powerful replacement for the
+:mod:`optparse` module.
+
+This means Python now supports three different modules for parsing
+command-line arguments: :mod:`getopt`, :mod:`optparse`, and
+:mod:`argparse`.  The :mod:`getopt` module closely resembles the C
+library's :c:func:`getopt` function, so it remains useful if you're writing a
+Python prototype that will eventually be rewritten in C.
+:mod:`optparse` becomes redundant, but there are no plans to remove it
+because there are many scripts still using it, and there's no
+automated way to update these scripts.  (Making the :mod:`argparse`
+API consistent with :mod:`optparse`'s interface was discussed but
+rejected as too messy and difficult.)
+
+In short, if you're writing a new script and don't need to worry
+about compatibility with earlier versions of Python, use
+:mod:`argparse` instead of :mod:`optparse`.
+
+Here's an example::
+
+    import argparse
+
+    parser = argparse.ArgumentParser(description='Command-line example.')
+
+    # Add optional switches
+    parser.add_argument('-v', action='store_true', dest='is_verbose',
+                        help='produce verbose output')
+    parser.add_argument('-o', action='store', dest='output',
+                        metavar='FILE',
+                        help='direct output to FILE instead of stdout')
+    parser.add_argument('-C', action='store', type=int, dest='context',
+                        metavar='NUM', default=0,
+                        help='display NUM lines of added context')
+
+    # Allow any number of additional arguments.
+    parser.add_argument(nargs='*', action='store', dest='inputs',
+                        help='input filenames (default is stdin)')
+
+    args = parser.parse_args()
+    print args.__dict__
+
+Unless you override it, :option:`-h` and :option:`--help` switches
+are automatically added, and produce neatly formatted output::
+
+    -> ./python.exe argparse-example.py --help
+    usage: argparse-example.py [-h] [-v] [-o FILE] [-C NUM] [inputs [inputs ...]]
+
+    Command-line example.
+
+    positional arguments:
+      inputs      input filenames (default is stdin)
+
+    optional arguments:
+      -h, --help  show this help message and exit
+      -v          produce verbose output
+      -o FILE     direct output to FILE instead of stdout
+      -C NUM      display NUM lines of added context
+
+As with :mod:`optparse`, the command-line switches and arguments
+are returned as an object with attributes named by the *dest* parameters::
+
+    -> ./python.exe argparse-example.py -v
+    {'output': None,
+     'is_verbose': True,
+     'context': 0,
+     'inputs': []}
+
+    -> ./python.exe argparse-example.py -v -o /tmp/output -C 4 file1 file2
+    {'output': '/tmp/output',
+     'is_verbose': True,
+     'context': 4,
+     'inputs': ['file1', 'file2']}
+
+:mod:`argparse` has much fancier validation than :mod:`optparse`; you
+can specify an exact number of arguments as an integer, 0 or more
+arguments by passing ``'*'``, 1 or more by passing ``'+'``, or an
+optional argument with ``'?'``.  A top-level parser can contain
+sub-parsers to define subcommands that have different sets of
+switches, as in ``svn commit``, ``svn checkout``, etc.  You can
+specify an argument's type as :class:`~argparse.FileType`, which will
+automatically open files for you and understands that ``'-'`` means
+standard input or output.

+PEP 391: Dictionary-Based Configuration For Logging
+====================================================
+
+.. XXX not documented in library reference yet; add link here once it's added.
+
+The :mod:`logging` module is very flexible; applications can define
+a tree of logging subsystems, and each logger in this tree can filter
+out certain messages, format them differently, and direct messages to
+a varying number of handlers.
+
+All this flexibility can require a lot of configuration.  You can
+write Python statements to create objects and set their properties,
+but a complex set-up requires verbose but boring code.
+:mod:`logging` also supports a :func:`~logging.config.fileConfig`
+function that parses a file, but the file format doesn't support
+configuring filters, and it's messier to generate programmatically.
+
+Python 2.7 adds a :func:`~logging.config.dictConfig` function that
+uses a dictionary to configure logging.  There are many ways to
+produce a dictionary from different sources: construct one with code;
+parse a file containing JSON; or use a YAML parsing library if one is
+installed.
+
+The following example configures two loggers, the root logger and a
+logger named "network".   Messages sent to the root logger will be
+sent to the system log using the syslog protocol, and messages
+to the "network" logger will be written to a :file:`network.log` file
+that will be rotated once the log reaches 1Mb.
+
+::
+
+    import logging
+    import logging.config
+
+    configdict = {
+     'version': 1,    # Configuration schema in use; must be 1 for now
+     'formatters': {
+         'standard': {
+             'format': ('%(asctime)s %(name)-15s '
+                        '%(levelname)-8s %(message)s')}},
+
+     'handlers': {'netlog': {'backupCount': 10,
+                         'class': 'logging.handlers.RotatingFileHandler',
+                         'filename': '/logs/network.log',
+                         'formatter': 'standard',
+                         'level': 'INFO',
+                         'maxBytes': 1024*1024},
+                  'syslog': {'class': 'logging.handlers.SysLogHandler',
+                             'formatter': 'standard',
+                             'level': 'ERROR'}},
+
+     # Specify all the subordinate loggers
+     'loggers': {
+                 'network': {
+                             'handlers': ['netlog']
+                 }
+     },
+     # Specify properties of the root logger
+     'root': {
+              'handlers': ['syslog']
+     },
+    }
+
+    # Set up configuration
+    logging.config.dictConfig(configdict)
+
+    # As an example, log two error messages
+    logger = logging.getLogger('/')
+    logger.error('Database not found')
+
+    netlogger = logging.getLogger('network')
+    netlogger.error('Connection failed')
+
+Three smaller enhancements to the :mod:`logging` module, all
+implemented by Vinay Sajip, are:
+
+.. rev79293
+
+* The :class:`~logging.handlers.SysLogHandler` class now supports
+  syslogging over TCP.  The constructor has a *socktype* parameter
+  giving the type of socket to use, either :const:`socket.SOCK_DGRAM`
+  for UDP or :const:`socket.SOCK_STREAM` for TCP.  The default
+  protocol remains UDP.
+
+* :class:`Logger` instances gained a :meth:`getChild` method that retrieves a
+  descendant logger using a relative path.  For example,
+  once you retrieve a logger by doing ``log = getLogger('app')``,
+  calling ``log.getChild('network.listen')`` is equivalent to
+  ``getLogger('app.network.listen')``.
+
+* The :class:`LoggerAdapter` class gained a :meth:`isEnabledFor` method
+  that takes a *level* and returns whether the underlying logger would
+  process a message of that level of importance.
+
+.. seealso::
+
+   :pep:`391` - Dictionary-Based Configuration For Logging
+     PEP written and implemented by Vinay Sajip.
+
+PEP 3106: Dictionary Views
+====================================================
+
+The dictionary methods :meth:`keys`, :meth:`values`, and :meth:`items`
+are different in Python 3.x.  They return an object called a :dfn:`view`
+instead of a fully materialized list.
+
+It's not possible to change the return values of :meth:`keys`,
+:meth:`values`, and :meth:`items` in Python 2.7 because too much code
+would break.  Instead the 3.x versions were added under the new names
+:meth:`viewkeys`, :meth:`viewvalues`, and :meth:`viewitems`.
+
+::
+
+    >>> d = dict((i*10, chr(65+i)) for i in range(26))
+    >>> d
+    {0: 'A', 130: 'N', 10: 'B', 140: 'O', 20: ..., 250: 'Z'}
+    >>> d.viewkeys()
+    dict_keys([0, 130, 10, 140, 20, 150, 30, ..., 250])
+
+Views can be iterated over, but the key and item views also behave
+like sets.  The ``&`` operator performs intersection, and ``|``
+performs a union::
+
+    >>> d1 = dict((i*10, chr(65+i)) for i in range(26))
+    >>> d2 = dict((i**.5, i) for i in range(1000))
+    >>> d1.viewkeys() & d2.viewkeys()
+    set([0.0, 10.0, 20.0, 30.0])
+    >>> d1.viewkeys() | range(0, 30)
+    set([0, 1, 130, 3, 4, 5, 6, ..., 120, 250])
+
+The view keeps track of the dictionary and its contents change as the
+dictionary is modified::
+
+    >>> vk = d.viewkeys()
+    >>> vk
+    dict_keys([0, 130, 10, ..., 250])
+    >>> d[260] = '&'
+    >>> vk
+    dict_keys([0, 130, 260, 10, ..., 250])
+
+However, note that you can't add or remove keys while you're iterating
+over the view::
+
+    >>> for k in vk:
+    ...     d[k*2] = k
+    ...
+    Traceback (most recent call last):
+      File "<stdin>", line 1, in <module>
+    RuntimeError: dictionary changed size during iteration
+
+You can use the view methods in Python 2.x code, and the 2to3
+converter will change them to the standard :meth:`keys`,
+:meth:`values`, and :meth:`items` methods.

+.. seealso::

+
+
+PEP 3137: The memoryview Object
+====================================================
+
+The :class:`memoryview` object provides a view of another object's
+memory content that matches the :class:`bytes` type's interface.
+
+    >>> import string
+    >>> m = memoryview(string.letters)
+    >>> m
+    <memory at 0x37f850>
+    >>> len(m)           # Returns length of underlying object
+    52
+    >>> m[0], m[25], m[26]   # Indexing returns one byte
+    ('a', 'z', 'A')
+    >>> m2 = m[0:26]         # Slicing returns another memoryview
+    >>> m2
+    <memory at 0x37f080>
+
+The content of the view can be converted to a string of bytes or
+a list of integers:
+
+    >>> m2.tobytes()
+    'abcdefghijklmnopqrstuvwxyz'
+    >>> m2.tolist()
+    [97, 98, 99, 100, 101, 102, 103, ... 121, 122]
+    >>>
+
+:class:`memoryview` objects allow modifying the underlying object if
+it's a mutable object.
+
+    >>> m2[0] = 75
+    Traceback (most recent call last):
+      File "<stdin>", line 1, in <module>
+    TypeError: cannot modify read-only memory
+    >>> b = bytearray(string.letters)  # Creating a mutable object
+    >>> b
+    bytearray(b'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ')
+    >>> mb = memoryview(b)
+    >>> mb[0] = '*'         # Assign to view, changing the bytearray.
+    >>> b[0:5]              # The bytearray has been changed.
+    bytearray(b'*bcde')
+    >>>

+     Backported to 2.7 by Antoine Pitrou; :issue:`2396`.
+
+
+
+Other Language Changes
+======================
+
+Some smaller changes made to the core Python language are:
+
+* The syntax for set literals has been backported from Python 3.x.
+  Curly brackets are used to surround the contents of the resulting
+  mutable set; set literals are
+  distinguished from dictionaries by not containing colons and values.
+  ``{}`` continues to represent an empty dictionary; use
+  ``set()`` for an empty set.
+
+    >>> {1,2,3,4,5}
+    set([1, 2, 3, 4, 5])
+    >>> set() # empty set
+    set([])
+    >>> {}    # empty dict
+    {}
+
+  Backported by Alexandre Vassalotti; :issue:`2335`.
+
+* Dictionary and set comprehensions are another feature backported from
+  3.x, generalizing list/generator comprehensions to use
+  the literal syntax for sets and dictionaries.
+
+    >>> {x: x*x for x in range(6)}
+    {0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 25}
+    >>> {('a'*x) for x in range(6)}
+    set(['', 'a', 'aa', 'aaa', 'aaaa', 'aaaaa'])
+
+  Backported by Alexandre Vassalotti; :issue:`2333`.
+
+* The :keyword:`with` statement can now use multiple context managers
+  in one statement.  Context managers are processed from left to right
+  and each one is treated as beginning a new :keyword:`with` statement.
+  This means that::
+
+   with A() as a, B() as b:
+       ... suite of statements ...
+
+  is equivalent to::
+
+   with A() as a:
+       with B() as b:
+           ... suite of statements ...
+
+  The :func:`contextlib.nested` function provides a very similar
+  function, so it's no longer necessary and has been deprecated.
+
+  (Proposed in http://codereview.appspot.com/53094; implemented by
+  Georg Brandl.)
+
+* Conversions between floating-point numbers and strings are
+  now correctly rounded on most platforms.  These conversions occur
+  in many different places: :func:`str` on
+  floats and complex numbers; the :class:`float` and :class:`complex`
+  constructors;
+  numeric formatting; serializing and
+  deserializing floats and complex numbers using the
+  :mod:`marshal`, :mod:`pickle`
+  and :mod:`json` modules;
+  parsing of float and imaginary literals in Python code;
+  and :class:`~decimal.Decimal`-to-float conversion.
+
+  Related to this, the :func:`repr` of a floating-point number *x*
+  now returns a result based on the shortest decimal string that's
+  guaranteed to round back to *x* under correct rounding (with
+  round-half-to-even rounding mode).  Previously it gave a string
+  based on rounding x to 17 decimal digits.
+
+  .. maybe add an example?
+
+  The rounding library responsible for this improvement works on
+  Windows and on Unix platforms using the gcc, icc, or suncc
+  compilers.  There may be a small number of platforms where correct
+  operation of this code cannot be guaranteed, so the code is not
+  used on such systems.  You can find out which code is being used
+  by checking :data:`sys.float_repr_style`,  which will be ``short``
+  if the new code is in use and ``legacy`` if it isn't.
+
+  Implemented by Eric Smith and Mark Dickinson, using David Gay's
+  :file:`dtoa.c` library; :issue:`7117`.
+
+* Conversions from long integers and regular integers to floating
+  point now round differently, returning the floating-point number
+  closest to the number.  This doesn't matter for small integers that
+  can be converted exactly, but for large numbers that will
+  unavoidably lose precision, Python 2.7 now approximates more
+  closely.  For example, Python 2.6 computed the following::
+
+    >>> n = 295147905179352891391
+    >>> float(n)
+    2.9514790517935283e+20
+    >>> n - long(float(n))
+    65535L
+
+  Python 2.7's floating-point result is larger, but much closer to the
+  true value::
+
+    >>> n = 295147905179352891391
+    >>> float(n)
+    2.9514790517935289e+20
+    >>> n - long(float(n))
+    -1L
+
+  (Implemented by Mark Dickinson; :issue:`3166`.)
+
+  Integer division is also more accurate in its rounding behaviours.  (Also
+  implemented by Mark Dickinson; :issue:`1811`.)
+
+* Implicit coercion for complex numbers has been removed; the interpreter
+  will no longer ever attempt to call a :meth:`__coerce__` method on complex
+  objects.  (Removed by Meador Inge and Mark Dickinson; :issue:`5211`.)
+
+* The :meth:`str.format` method now supports automatic numbering of the replacement
+  fields.  This makes using :meth:`str.format` more closely resemble using
+  ``%s`` formatting::
+
+    >>> '{}:{}:{}'.format(2009, 04, 'Sunday')
+    '2009:4:Sunday'
+    >>> '{}:{}:{day}'.format(2009, 4, day='Sunday')
+    '2009:4:Sunday'
+
+  The auto-numbering takes the fields from left to right, so the first ``{...}``
+  specifier will use the first argument to :meth:`str.format`, the next
+  specifier will use the next argument, and so on.  You can't mix auto-numbering
+  and explicit numbering -- either number all of your specifier fields or none
+  of them -- but you can mix auto-numbering and named fields, as in the second
+  example above.  (Contributed by Eric Smith; :issue:`5237`.)
+
+  Complex numbers now correctly support usage with :func:`format`,
+  and default to being right-aligned.
+  Specifying a precision or comma-separation applies to both the real
+  and imaginary parts of the number, but a specified field width and
+  alignment is applied to the whole of the resulting ``1.5+3j``
+  output.  (Contributed by Eric Smith; :issue:`1588` and :issue:`7988`.)
+
+  The 'F' format code now always formats its output using uppercase characters,
+  so it will now produce 'INF' and 'NAN'.
+  (Contributed by Eric Smith; :issue:`3382`.)
+
+  A low-level change: the :meth:`object.__format__` method now triggers
+  a :exc:`PendingDeprecationWarning` if it's passed a format string,
+  because the :meth:`__format__` method for :class:`object` converts
+  the object to a string representation and formats that.  Previously
+  the method silently applied the format string to the string
+  representation, but that could hide mistakes in Python code.  If
+  you're supplying formatting information such as an alignment or
+  precision, presumably you're expecting the formatting to be applied
+  in some object-specific way.  (Fixed by Eric Smith; :issue:`7994`.)
+
+* The :func:`int` and :func:`long` types gained a ``bit_length``
+  method that returns the number of bits necessary to represent
+  its argument in binary::
+
+      >>> n = 37
+      >>> bin(n)
+      '0b100101'
+      >>> n.bit_length()
+      6
+      >>> n = 2**123-1
+      >>> n.bit_length()
+      123
+      >>> (n+1).bit_length()
+      124
+
+  (Contributed by Fredrik Johansson and Victor Stinner; :issue:`3439`.)
+
+* The :keyword:`import` statement will no longer try a relative import
+  if an absolute import (e.g. ``from .os import sep``) fails.  This
+  fixes a bug, but could possibly break certain :keyword:`import`
+  statements that were only working by accident.  (Fixed by Meador Inge;
+  :issue:`7902`.)
+
+* It's now possible for a subclass of the built-in :class:`unicode` type
+  to override the :meth:`__unicode__` method.  (Implemented by
+  Victor Stinner; :issue:`1583863`.)
+
+* The :class:`bytearray` type's :meth:`~bytearray.translate` method now accepts
+  ``None`` as its first argument.  (Fixed by Georg Brandl;
+  :issue:`4759`.)
+
+  .. bytearray doesn't seem to be documented
+
+* When using ``@classmethod`` and ``@staticmethod`` to wrap
+  methods as class or static methods, the wrapper object now
+  exposes the wrapped function as their :attr:`__func__` attribute.
+  (Contributed by Amaury Forgeot d'Arc, after a suggestion by
+  George Sakkis; :issue:`5982`.)
+
+* When a restricted set of attributes were set using ``__slots__``,
+  deleting an unset attribute would not raise :exc:`AttributeError`
+  as you would expect.  Fixed by Benjamin Peterson; :issue:`7604`.)
+
+* Two new encodings are now supported: "cp720", used primarily for
+  Arabic text; and "cp858", a variant of CP 850 that adds the euro
+  symbol.  (CP720 contributed by Alexander Belchenko and Amaury
+  Forgeot d'Arc in :issue:`1616979`; CP858 contributed by Tim Hatch in
+  :issue:`8016`.)
+
+* The :class:`file` object will now set the :attr:`filename` attribute
+  on the :exc:`IOError` exception when trying to open a directory
+  on POSIX platforms (noted by Jan Kaliszewski; :issue:`4764`), and
+  now explicitly checks for and forbids writing to read-only file objects
+  instead of trusting the C library to catch and report the error
+  (fixed by Stefan Krah; :issue:`5677`).
+
+* The Python tokenizer now translates line endings itself, so the
+  :func:`compile` built-in function now accepts code using any
+  line-ending convention.  Additionally, it no longer requires that the
+  code end in a newline.
+
+* Extra parentheses in function definitions are illegal in Python 3.x,
+  meaning that you get a syntax error from ``def f((x)): pass``.  In
+  Python3-warning mode, Python 2.7 will now warn about this odd usage.
+  (Noted by James Lingard; :issue:`7362`.)
+
+* It's now possible to create weak references to old-style class
+  objects.  New-style classes were always weak-referenceable.  (Fixed
+  by Antoine Pitrou; :issue:`8268`.)
+
+* When a module object is garbage-collected, the module's dictionary is
+  now only cleared if no one else is holding a reference to the
+  dictionary (:issue:`7140`).
+

+
+Interpreter Changes
+-------------------------------
+
+A new environment variable, :envvar:`PYTHONWARNINGS`,
+allows controlling warnings.  It should be set to a string
+containing warning settings, equivalent to those
+used with the :option:`-W` switch, separated by commas.
+(Contributed by Brian Curtin; :issue:`7301`.)
+
+For example, the following setting will print warnings every time
+they occur, but turn warnings from the :mod:`Cookie` module into an
+error.  (The exact syntax for setting an environment variable varies
+across operating systems and shells.)
+
+::
+
+  export PYTHONWARNINGS=all,error:::Cookie:0
+
+.. ======================================================================
+
+
+Optimizations
+-------------
+
+Several performance enhancements have been added:
+
+.. * A new :program:`configure` option, :option:`--with-computed-gotos`,
+   compiles the main bytecode interpreter loop using a new dispatch
+   mechanism that gives speedups of up to 20%, depending on the system
+   and benchmark.  The new mechanism is only supported on certain
+   compilers, such as gcc, SunPro, and icc.
+
+* A new opcode was added to perform the initial setup for
+  :keyword:`with` statements, looking up the :meth:`__enter__` and
+  :meth:`__exit__` methods.  (Contributed by Benjamin Peterson.)
+
+* The garbage collector now performs better for one common usage
+  pattern: when many objects are being allocated without deallocating
+  any of them.  This would previously take quadratic
+  time for garbage collection, but now the number of full garbage collections
+  is reduced as the number of objects on the heap grows.
+  The new logic only performs a full garbage collection pass when
+  the middle generation has been collected 10 times and when the
+  number of survivor objects from the middle generation exceeds 10% of
+  the number of objects in the oldest generation.  (Suggested by Martin
+  von Löwis and implemented by Antoine Pitrou; :issue:`4074`.)
+
+* The garbage collector tries to avoid tracking simple containers
+  which can't be part of a cycle. In Python 2.7, this is now true for
+  tuples and dicts containing atomic types (such as ints, strings,
+  etc.). Transitively, a dict containing tuples of atomic types won't
+  be tracked either. This helps reduce the cost of each
+  garbage collection by decreasing the number of objects to be
+  considered and traversed by the collector.
+  (Contributed by Antoine Pitrou; :issue:`4688`.)
+
+* Long integers are now stored internally either in base 2**15 or in base
+  2**30, the base being determined at build time.  Previously, they
+  were always stored in base 2**15.  Using base 2**30 gives
+  significant performance improvements on 64-bit machines, but
+  benchmark results on 32-bit machines have been mixed.  Therefore,
+  the default is to use base 2**30 on 64-bit machines and base 2**15
+  on 32-bit machines; on Unix, there's a new configure option
+  :option:`--enable-big-digits` that can be used to override this default.
+
+  Apart from the performance improvements this change should be
+  invisible to end users, with one exception: for testing and
+  debugging purposes there's a new structseq :data:`sys.long_info` that
+  provides information about the internal format, giving the number of
+  bits per digit and the size in bytes of the C type used to store
+  each digit::
+
+     >>> import sys
+     >>> sys.long_info
+     sys.long_info(bits_per_digit=30, sizeof_digit=4)
+
+  (Contributed by Mark Dickinson; :issue:`4258`.)
+
+  Another set of changes made long objects a few bytes smaller: 2 bytes
+  smaller on 32-bit systems and 6 bytes on 64-bit.
+  (Contributed by Mark Dickinson; :issue:`5260`.)
+
+* The division algorithm for long integers has been made faster
+  by tightening the inner loop, doing shifts instead of multiplications,
+  and fixing an unnecessary extra iteration.
+  Various benchmarks show speedups of between 50% and 150% for long
+  integer divisions and modulo operations.
+  (Contributed by Mark Dickinson; :issue:`5512`.)
+  Bitwise operations are also significantly faster (initial patch by
+  Gregory Smith; :issue:`1087418`).
+
+* The implementation of ``%`` checks for the left-side operand being
+  a Python string and special-cases it; this results in a 1-3%
+  performance increase for applications that frequently use ``%``
+  with strings, such as templating libraries.
+  (Implemented by Collin Winter; :issue:`5176`.)
+
+* List comprehensions with an ``if`` condition are compiled into
+  faster bytecode.  (Patch by Antoine Pitrou, back-ported to 2.7
+  by Jeffrey Yasskin; :issue:`4715`.)
+
+* Converting an integer or long integer to a decimal string was made
+  faster by special-casing base 10 instead of using a generalized
+  conversion function that supports arbitrary bases.
+  (Patch by Gawain Bolton; :issue:`6713`.)
+
+* The :meth:`split`, :meth:`replace`, :meth:`rindex`,
+  :meth:`rpartition`, and :meth:`rsplit` methods of string-like types
+  (strings, Unicode strings, and :class:`bytearray` objects) now use a
+  fast reverse-search algorithm instead of a character-by-character
+  scan.  This is sometimes faster by a factor of 10.  (Added by
+  Florent Xicluna; :issue:`7462` and :issue:`7622`.)
+
+* The :mod:`pickle` and :mod:`cPickle` modules now automatically
+  intern the strings used for attribute names, reducing memory usage
+  of the objects resulting from unpickling.  (Contributed by Jake
+  McGuire; :issue:`5084`.)
+
+* The :mod:`cPickle` module now special-cases dictionaries,
+  nearly halving the time required to pickle them.
+  (Contributed by Collin Winter; :issue:`5670`.)
+
+.. ======================================================================
+
+New and Improved Modules
+========================
+
+As in every release, Python's standard library received a number of
+enhancements and bug fixes.  Here's a partial list of the most notable
+changes, sorted alphabetically by module name. Consult the
+:file:`Misc/NEWS` file in the source tree for a more complete list of
+changes, or look through the Subversion logs for all the details.
+
+* The :mod:`bdb` module's base debugging class :class:`~bdb.Bdb`
+  gained a feature for skipping modules.  The constructor
+  now takes an iterable containing glob-style patterns such as
+  ``django.*``; the debugger will not step into stack frames
+  from a module that matches one of these patterns.
+  (Contributed by Maru Newby after a suggestion by
+  Senthil Kumaran; :issue:`5142`.)
+
+* The :mod:`binascii` module now supports the buffer API, so it can be
+  used with :class:`memoryview` instances and other similar buffer objects.
+  (Backported from 3.x by Florent Xicluna; :issue:`7703`.)
+
+* Updated module: the :mod:`bsddb` module has been updated from 4.7.2devel9
+  to version 4.8.4 of
+  `the pybsddb package <http://www.jcea.es/programacion/pybsddb.htm>`__.
+  The new version features better Python 3.x compatibility, various bug fixes,
+  and adds several new BerkeleyDB flags and methods.
+  (Updated by Jesús Cea Avión; :issue:`8156`.  The pybsddb
+  changelog can be read at http://hg.jcea.es/pybsddb/file/tip/ChangeLog.)
+
+* The :mod:`bz2` module's :class:`~bz2.BZ2File` now supports the context
+  management protocol, so you can write ``with bz2.BZ2File(...) as f:``.
+  (Contributed by Hagen Fürstenau; :issue:`3860`.)
+
+* New class: the :class:`~collections.Counter` class in the :mod:`collections`
+  module is useful for tallying data.  :class:`~collections.Counter` instances
+  behave mostly like dictionaries but return zero for missing keys instead of
+  raising a :exc:`KeyError`:
+
+  .. doctest::
+     :options: +NORMALIZE_WHITESPACE
+
+     >>> from collections import Counter
+     >>> c = Counter()
+     >>> for letter in 'here is a sample of english text':
+     ...   c[letter] += 1
+     ...
+     >>> c
+     Counter({' ': 6, 'e': 5, 's': 3, 'a': 2, 'i': 2, 'h': 2,
+     'l': 2, 't': 2, 'g': 1, 'f': 1, 'm': 1, 'o': 1, 'n': 1,
+     'p': 1, 'r': 1, 'x': 1})
+     >>> c['e']
+     5
+     >>> c['z']
+     0
+
+  There are three additional :class:`~collections.Counter` methods.
+  :meth:`~collections.Counter.most_common` returns the N most common
+  elements and their counts.  :meth:`~collections.Counter.elements`
+  returns an iterator over the contained elements, repeating each
+  element as many times as its count.
+  :meth:`~collections.Counter.subtract` takes an iterable and
+  subtracts one for each element instead of adding; if the argument is
+  a dictionary or another :class:`Counter`, the counts are
+  subtracted. ::
+
+    >>> c.most_common(5)
+    [(' ', 6), ('e', 5), ('s', 3), ('a', 2), ('i', 2)]
+    >>> c.elements() ->
+       'a', 'a', ' ', ' ', ' ', ' ', ' ', ' ',
+       'e', 'e', 'e', 'e', 'e', 'g', 'f', 'i', 'i',
+       'h', 'h', 'm', 'l', 'l', 'o', 'n', 'p', 's',
+       's', 's', 'r', 't', 't', 'x'
+    >>> c['e']
+    5
+    >>> c.subtract('very heavy on the letter e')
+    >>> c['e']    # Count is now lower
+    -1
+
+  Contributed by Raymond Hettinger; :issue:`1696199`.
+
+  .. revision 79660
+
+  New class: :class:`~collections.OrderedDict` is described in the earlier
+  section :ref:`pep-0372`.
+
+  New method: The :class:`~collections.deque` data type now has a
+  :meth:`~collections.deque.count` method that returns the number of
+  contained elements equal to the supplied argument *x*, and a
+  :meth:`~collections.deque.reverse` method that reverses the elements
+  of the deque in-place.  :class:`deque` also exposes its maximum
+  length as the read-only :attr:`~collections.deque.maxlen` attribute.
+  (Both features added by Raymond Hettinger.)
+
+  The :class:`~collections.namedtuple` class now has an optional *rename* parameter.
+  If *rename* is true, field names that are invalid because they've
+  been repeated or aren't legal Python identifiers will be
+  renamed to legal names that are derived from the field's
+  position within the list of fields:
+
+     >>> from collections import namedtuple
+     >>> T = namedtuple('T', ['field1', '$illegal', 'for', 'field2'], rename=True)
+     >>> T._fields
+     ('field1', '_1', '_2', 'field2')
+
+  (Added by Raymond Hettinger; :issue:`1818`.)
+
+  Finally, the :class:`~collections.Mapping` abstract base class now
+  returns :const:`NotImplemented` if a mapping is compared to
+  another type that isn't a :class:`Mapping`.
+  (Fixed by Daniel Stutzbach; :issue:`8729`.)
+
+* Constructors for the parsing classes in the :mod:`ConfigParser` module now
+  take a *allow_no_value* parameter, defaulting to false; if true,
+  options without values will be allowed.  For example::
+
+    >>> import ConfigParser, StringIO
+    >>> sample_config = """
+    ... [mysqld]
+    ... user = mysql
+    ... pid-file = /var/run/mysqld/mysqld.pid
+    ... skip-bdb
+    ... """
+    >>> config = ConfigParser.RawConfigParser(allow_no_value=True)
+    >>> config.readfp(StringIO.StringIO(sample_config))
+    >>> config.get('mysqld', 'user')
+    'mysql'
+    >>> print config.get('mysqld', 'skip-bdb')
+    None
+    >>> print config.get('mysqld', 'unknown')
+    Traceback (most recent call last):
+      ...
+    NoOptionError: No option 'unknown' in section: 'mysqld'
+
+  (Contributed by Mats Kindahl; :issue:`7005`.)
+
+* Deprecated function: :func:`contextlib.nested`, which allows
+  handling more than one context manager with a single :keyword:`with`
+  statement, has been deprecated, because the :keyword:`with` statement
+  now supports multiple context managers.
+
+* The :mod:`cookielib` module now ignores cookies that have an invalid
+  version field, one that doesn't contain an integer value.  (Fixed by
+  John J. Lee; :issue:`3924`.)
+
+* The :mod:`copy` module's :func:`~copy.deepcopy` function will now
+  correctly copy bound instance methods.  (Implemented by
+  Robert Collins; :issue:`1515`.)
+
+* The :mod:`ctypes` module now always converts ``None`` to a C NULL
+  pointer for arguments declared as pointers.  (Changed by Thomas
+  Heller; :issue:`4606`.)  The underlying `libffi library
+  <http://sourceware.org/libffi/>`__ has been updated to version
+  3.0.9, containing various fixes for different platforms.  (Updated
+  by Matthias Klose; :issue:`8142`.)
+
+* New method: the :mod:`datetime` module's :class:`~datetime.timedelta` class
+  gained a :meth:`~datetime.timedelta.total_seconds` method that returns the
+  number of seconds in the duration.  (Contributed by Brian Quinlan; :issue:`5788`.)
+
+* New method: the :class:`~decimal.Decimal` class gained a
+  :meth:`~decimal.Decimal.from_float` class method that performs an exact
+  conversion of a floating-point number to a :class:`~decimal.Decimal`.
+  This exact conversion strives for the
+  closest decimal approximation to the floating-point representation's value;
+  the resulting decimal value will therefore still include the inaccuracy,
+  if any.
+  For example, ``Decimal.from_float(0.1)`` returns
+  ``Decimal('0.1000000000000000055511151231257827021181583404541015625')``.
+  (Implemented by Raymond Hettinger; :issue:`4796`.)
+
+  Comparing instances of :class:`Decimal` with floating-point
+  numbers now produces sensible results based on the numeric values
+  of the operands.  Previously such comparisons would fall back to
+  Python's default rules for comparing objects, which produced arbitrary
+  results based on their type.  Note that you still cannot combine
+  :class:`Decimal` and floating-point in other operations such as addition,
+  since you should be explicitly choosing how to convert between float and
+  :class:`Decimal`.
+  (Fixed by Mark Dickinson; :issue:`2531`.)
+
+  The constructor for :class:`~decimal.Decimal` now accepts
+  floating-point numbers (added by Raymond Hettinger; :issue:`8257`)
+  and non-European Unicode characters such as Arabic-Indic digits
+  (contributed by Mark Dickinson; :issue:`6595`).
+
+  Most of the methods of the :class:`~decimal.Context` class now accept integers
+  as well as :class:`~decimal.Decimal` instances; the only exceptions are the
+  :meth:`~decimal.Context.canonical` and :meth:`~decimal.Context.is_canonical`
+  methods.  (Patch by Juan José Conti; :issue:`7633`.)
+
+  When using :class:`~decimal.Decimal` instances with a string's
+  :meth:`~str.format` method, the default alignment was previously
+  left-alignment.  This has been changed to right-alignment, which is
+  more sensible for numeric types.  (Changed by Mark Dickinson; :issue:`6857`.)
+
+  Comparisons involving a signaling NaN value (or ``sNAN``) now signal
+  :const:`InvalidOperation` instead of silently returning a true or
+  false value depending on the comparison operator.  Quiet NaN values
+  (or ``NaN``) are now hashable.  (Fixed by Mark Dickinson;
+  :issue:`7279`.)
+
+* The :mod:`difflib` module now produces output that is more
+  compatible with modern :command:`diff`/:command:`patch` tools
+  through one small change, using a tab character instead of spaces as
+  a separator in the header giving the filename.  (Fixed by Anatoly
+  Techtonik; :issue:`7585`.)
+
+* The Distutils ``sdist`` command now always regenerates the
+  :file:`MANIFEST` file, since even if the :file:`MANIFEST.in` or
+  :file:`setup.py` files haven't been modified, the user might have
+  created some new files that should be included.
+  (Fixed by Tarek Ziadé; :issue:`8688`.)
+
+* The :mod:`doctest` module's :const:`IGNORE_EXCEPTION_DETAIL` flag
+  will now ignore the name of the module containing the exception
+  being tested.  (Patch by Lennart Regebro; :issue:`7490`.)
+
+* The :mod:`email` module's :class:`~email.message.Message` class will
+  now accept a Unicode-valued payload, automatically converting the
+  payload to the encoding specified by :attr:`output_charset`.
+  (Added by R. David Murray; :issue:`1368247`.)
+
+* The :class:`~fractions.Fraction` class now accepts a single float or
+  :class:`~decimal.Decimal` instance, or two rational numbers, as
+  arguments to its constructor.  (Implemented by Mark Dickinson;
+  rationals added in :issue:`5812`, and float/decimal in
+  :issue:`8294`.)
+
+  Ordering comparisons (``<``, ``<=``, ``>``, ``>=``) between
+  fractions and complex numbers now raise a :exc:`TypeError`.
+  This fixes an oversight, making the :class:`Fraction` match the other
+  numeric types.
+
+  .. revision 79455
+
+* New class: :class:`~ftplib.FTP_TLS` in
+  the :mod:`ftplib` module provides secure FTP
+  connections using TLS encapsulation of authentication as well as
+  subsequent control and data transfers.
+  (Contributed by Giampaolo Rodola; :issue:`2054`.)
+
+  The :meth:`~ftplib.FTP.storbinary` method for binary uploads can now restart
+  uploads thanks to an added *rest* parameter (patch by Pablo Mouzo;
+  :issue:`6845`.)
+
+* New class decorator: :func:`total_ordering` in the :mod:`functools`
+  module takes a class that defines an :meth:`__eq__` method and one of
+  :meth:`__lt__`, :meth:`__le__`, :meth:`__gt__`, or :meth:`__ge__`,
+  and generates the missing comparison methods.  Since the
+  :meth:`__cmp__` method is being deprecated in Python 3.x,
+  this decorator makes it easier to define ordered classes.
+  (Added by Raymond Hettinger; :issue:`5479`.)
+
+  New function: :func:`cmp_to_key` will take an old-style comparison
+  function that expects two arguments and return a new callable that
+  can be used as the *key* parameter to functions such as
+  :func:`sorted`, :func:`min` and :func:`max`, etc.  The primary
+  intended use is to help with making code compatible with Python 3.x.
+  (Added by Raymond Hettinger.)
+
+* New function: the :mod:`gc` module's :func:`~gc.is_tracked` returns
+  true if a given instance is tracked by the garbage collector, false
+  otherwise. (Contributed by Antoine Pitrou; :issue:`4688`.)
+
+* The :mod:`gzip` module's :class:`~gzip.GzipFile` now supports the context
+  management protocol, so you can write ``with gzip.GzipFile(...) as f:``
+  (contributed by Hagen Fürstenau; :issue:`3860`), and it now implements
+  the :class:`io.BufferedIOBase` ABC, so you can wrap it with
+  :class:`io.BufferedReader` for faster processing
+  (contributed by Nir Aides; :issue:`7471`).
+  It's also now possible to override the modification time
+  recorded in a gzipped file by providing an optional timestamp to
+  the constructor.  (Contributed by Jacques Frechet; :issue:`4272`.)
+
+  Files in gzip format can be padded with trailing zero bytes; the
+  :mod:`gzip` module will now consume these trailing bytes.  (Fixed by
+  Tadek Pietraszek and Brian Curtin; :issue:`2846`.)
+
+* New attribute: the :mod:`hashlib` module now has an :attr:`~hashlib.hashlib.algorithms`
+  attribute containing a tuple naming the supported algorithms.
+  In Python 2.7, ``hashlib.algorithms`` contains
+  ``('md5', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512')``.
+  (Contributed by Carl Chenet; :issue:`7418`.)
+
+* The default :class:`~httplib.HTTPResponse` class used by the :mod:`httplib` module now
+  supports buffering, resulting in much faster reading of HTTP responses.
+  (Contributed by Kristján Valur Jónsson; :issue:`4879`.)
+
+  The :class:`~httplib.HTTPConnection` and :class:`~httplib.HTTPSConnection` classes
+  now support a *source_address* parameter, a ``(host, port)`` 2-tuple
+  giving the source address that will be used for the connection.
+  (Contributed by Eldon Ziegler; :issue:`3972`.)
+
+* The :mod:`ihooks` module now supports relative imports.  Note that
+  :mod:`ihooks` is an older module for customizing imports,
+  superseded by the :mod:`imputil` module added in Python 2.0.
+  (Relative import support added by Neil Schemenauer.)
+
+  .. revision 75423
+
+* The :mod:`imaplib` module now supports IPv6 addresses.
+  (Contributed by Derek Morr; :issue:`1655`.)
+
+* New function: the :mod:`inspect` module's :func:`~inspect.getcallargs`
+  takes a callable and its positional and keyword arguments,
+  and figures out which of the callable's parameters will receive each argument,
+  returning a dictionary mapping argument names to their values.  For example::
+
+    >>> from inspect import getcallargs
+    >>> def f(a, b=1, *pos, **named):
+    ...     pass
+    >>> getcallargs(f, 1, 2, 3)
+    {'a': 1, 'b': 2, 'pos': (3,), 'named': {}}
+    >>> getcallargs(f, a=2, x=4)
+    {'a': 2, 'b': 1, 'pos': (), 'named': {'x': 4}}
+    >>> getcallargs(f)
+    Traceback (most recent call last):
+    ...
+    TypeError: f() takes at least 1 argument (0 given)
+
+  Contributed by George Sakkis; :issue:`3135`.
+
+* Updated module: The :mod:`io` library has been upgraded to the version shipped with
+  Python 3.1.  For 3.1, the I/O library was entirely rewritten in C
+  and is 2 to 20 times faster depending on the task being performed.  The
+  original Python version was renamed to the :mod:`_pyio` module.
+
+  One minor resulting change: the :class:`io.TextIOBase` class now
+  has an :attr:`errors` attribute giving the error setting
+  used for encoding and decoding errors (one of ``'strict'``, ``'replace'``,
+  ``'ignore'``).
+
+  The :class:`io.FileIO` class now raises an :exc:`OSError` when passed
+  an invalid file descriptor.  (Implemented by Benjamin Peterson;
+  :issue:`4991`.)  The :meth:`~io.IOBase.truncate` method now preserves the
+  file position; previously it would change the file position to the
+  end of the new file.  (Fixed by Pascal Chambon; :issue:`6939`.)
+
+* New function: ``itertools.compress(data, selectors)`` takes two
+  iterators.  Elements of *data* are returned if the corresponding
+  value in *selectors* is true::
+
+    itertools.compress('ABCDEF', [1,0,1,0,1,1]) =>
+      A, C, E, F
+
+  .. maybe here is better to use >>> list(itertools.compress(...)) instead
+
+  New function: ``itertools.combinations_with_replacement(iter, r)``
+  returns all the possible *r*-length combinations of elements from the
+  iterable *iter*.  Unlike :func:`~itertools.combinations`, individual elements
+  can be repeated in the generated combinations::
+
+    itertools.combinations_with_replacement('abc', 2) =>
+      ('a', 'a'), ('a', 'b'), ('a', 'c'),
+      ('b', 'b'), ('b', 'c'), ('c', 'c')
+
+  Note that elements are treated as unique depending on their position
+  in the input, not their actual values.
+
+  The :func:`itertools.count` function now has a *step* argument that
+  allows incrementing by values other than 1.  :func:`~itertools.count` also
+  now allows keyword arguments, and using non-integer values such as
+  floats or :class:`~decimal.Decimal` instances.  (Implemented by Raymond
+  Hettinger; :issue:`5032`.)
+
+  :func:`itertools.combinations` and :func:`itertools.product`
+  previously raised :exc:`ValueError` for values of *r* larger than
+  the input iterable.  This was deemed a specification error, so they
+  now return an empty iterator.  (Fixed by Raymond Hettinger; :issue:`4816`.)
+
+* Updated module: The :mod:`json` module was upgraded to version 2.0.9 of the
+  simplejson package, which includes a C extension that makes
+  encoding and decoding faster.
+  (Contributed by Bob Ippolito; :issue:`4136`.)
+
+  To support the new :class:`collections.OrderedDict` type, :func:`json.load`
+  now has an optional *object_pairs_hook* parameter that will be called
+  with any object literal that decodes to a list of pairs.
+  (Contributed by Raymond Hettinger; :issue:`5381`.)
+
+* The :mod:`mailbox` module's :class:`Maildir` class now records the
+  timestamp on the directories it reads, and only re-reads them if the
+  modification time has subsequently changed.  This improves
+  performance by avoiding unneeded directory scans.  (Fixed by
+  A.M. Kuchling and Antoine Pitrou; :issue:`1607951`, :issue:`6896`.)
+
+* New functions: the :mod:`math` module gained
+  :func:`~math.erf` and :func:`~math.erfc` for the error function and the complementary error function,
+  :func:`~math.expm1` which computes ``e**x - 1`` with more precision than
+  using :func:`~math.exp` and subtracting 1,
+  :func:`~math.gamma` for the Gamma function, and
+  :func:`~math.lgamma` for the natural log of the Gamma function.
+  (Contributed by Mark Dickinson and nirinA raseliarison; :issue:`3366`.)
+
+* The :mod:`multiprocessing` module's :class:`Manager*` classes
+  can now be passed a callable that will be called whenever
+  a subprocess is started, along with a set of arguments that will be
+  passed to the callable.
+  (Contributed by lekma; :issue:`5585`.)
+
+  The :class:`~multiprocessing.Pool` class, which controls a pool of worker processes,
+  now has an optional *maxtasksperchild* parameter.  Worker processes
+  will perform the specified number of tasks and then exit, causing the
+  :class:`~multiprocessing.Pool` to start a new worker.  This is useful if tasks may leak
+  memory or other resources, or if some tasks will cause the worker to
+  become very large.
+  (Contributed by Charles Cazabon; :issue:`6963`.)
+
+* The :mod:`nntplib` module now supports IPv6 addresses.
+  (Contributed by Derek Morr; :issue:`1664`.)
+
+* New functions: the :mod:`os` module wraps the following POSIX system
+  calls: :func:`~os.getresgid` and :func:`~os.getresuid`, which return the
+  real, effective, and saved GIDs and UIDs;
+  :func:`~os.setresgid` and :func:`~os.setresuid`, which set
+  real, effective, and saved GIDs and UIDs to new values;
+  :func:`~os.initgroups`, which initialize the group access list
+  for the current process.  (GID/UID functions
+  contributed by Travis H.; :issue:`6508`.  Support for initgroups added
+  by Jean-Paul Calderone; :issue:`7333`.)
+
+  The :func:`os.fork` function now re-initializes the import lock in
+  the child process; this fixes problems on Solaris when :func:`~os.fork`
+  is called from a thread.  (Fixed by Zsolt Cserna; :issue:`7242`.)
+
+* In the :mod:`os.path` module, the :func:`~os.path.normpath` and
+  :func:`~os.path.abspath` functions now preserve Unicode; if their input path
+  is a Unicode string, the return value is also a Unicode string.
+  (:meth:`~os.path.normpath` fixed by Matt Giuca in :issue:`5827`;
+  :meth:`~os.path.abspath` fixed by Ezio Melotti in :issue:`3426`.)
+
+* The :mod:`pydoc` module now has help for the various symbols that Python
+  uses.  You can now do ``help('<<')`` or ``help('@')``, for example.
+  (Contributed by David Laban; :issue:`4739`.)
+
+* The :mod:`re` module's :func:`~re.split`, :func:`~re.sub`, and :func:`~re.subn`
+  now accept an optional *flags* argument, for consistency with the
+  other functions in the module.  (Added by Gregory P. Smith.)
+
+* New function: :func:`~runpy.run_path` in the :mod:`runpy` module
+  will execute the code at a provided *path* argument.  *path* can be
+  the path of a Python source file (:file:`example.py`), a compiled
+  bytecode file (:file:`example.pyc`), a directory
+  (:file:`./package/`), or a zip archive (:file:`example.zip`).  If a
+  directory or zip path is provided, it will be added to the front of
+  ``sys.path`` and the module :mod:`__main__` will be imported.  It's
+  expected that the directory or zip contains a :file:`__main__.py`;
+  if it doesn't, some other :file:`__main__.py` might be imported from
+  a location later in ``sys.path``.  This makes more of the machinery
+  of :mod:`runpy` available to scripts that want to mimic the way
+  Python's command line processes an explicit path name.
+  (Added by Nick Coghlan; :issue:`6816`.)
+
+* New function: in the :mod:`shutil` module, :func:`~shutil.make_archive`
+  takes a filename, archive type (zip or tar-format), and a directory
+  path, and creates an archive containing the directory's contents.
+  (Added by Tarek Ziadé.)
+
+  :mod:`shutil`'s :func:`~shutil.copyfile` and :func:`~shutil.copytree`
+  functions now raise a :exc:`~shutil.SpecialFileError` exception when
+  asked to copy a named pipe.  Previously the code would treat
+  named pipes like a regular file by opening them for reading, and
+  this would block indefinitely.  (Fixed by Antoine Pitrou; :issue:`3002`.)
+
+* The :mod:`signal` module no longer re-installs the signal handler
+  unless this is truly necessary, which fixes a bug that could make it
+  impossible to catch the EINTR signal robustly.  (Fixed by
+  Charles-Francois Natali; :issue:`8354`.)
+
+* New functions: in the :mod:`site` module, three new functions
+  return various site- and user-specific paths.
+  :func:`~site.getsitepackages` returns a list containing all
+  global site-packages directories,
+  :func:`~site.getusersitepackages` returns the path of the user's
+  site-packages directory, and
+  :func:`~site.getuserbase` returns the value of the :envvar:`USER_BASE`
+  environment variable, giving the path to a directory that can be used
+  to store data.
+  (Contributed by Tarek Ziadé; :issue:`6693`.)
+
+  The :mod:`site` module now reports exceptions occurring
+  when the :mod:`sitecustomize` module is imported, and will no longer
+  catch and swallow the :exc:`KeyboardInterrupt` exception.  (Fixed by
+  Victor Stinner; :issue:`3137`.)
+
+* The :func:`~socket.create_connection` function
+  gained a *source_address* parameter, a ``(host, port)`` 2-tuple
+  giving the source address that will be used for the connection.
+  (Contributed by Eldon Ziegler; :issue:`3972`.)
+
+  The :meth:`~socket.socket.recv_into` and :meth:`~socket.socket.recvfrom_into`
+  methods will now write into objects that support the buffer API, most usefully
+  the :class:`bytearray` and :class:`memoryview` objects.  (Implemented by
+  Antoine Pitrou; :issue:`8104`.)
+
+* The :mod:`SocketServer` module's :class:`~SocketServer.TCPServer` class now
+  supports socket timeouts and disabling the Nagle algorithm.
+  The :attr:`~SocketServer.TCPServer.disable_nagle_algorithm` class attribute
+  defaults to False; if overridden to be True,
+  new request connections will have the TCP_NODELAY option set to
+  prevent buffering many small sends into a single TCP packet.
+  The :attr:`~SocketServer.TCPServer.timeout` class attribute can hold
+  a timeout in seconds that will be applied to the request socket; if
+  no request is received within that time, :meth:`handle_timeout`
+  will be called and :meth:`handle_request` will return.
+  (Contributed by Kristján Valur Jónsson; :issue:`6192` and :issue:`6267`.)
+
+* Updated module: the :mod:`sqlite3` module has been updated to
+  version 2.6.0 of the `pysqlite package <http://code.google.com/p/pysqlite/>`__. Version 2.6.0 includes a number of bugfixes, and adds
+  the ability to load SQLite extensions from shared libraries.
+  Call the ``enable_load_extension(True)`` method to enable extensions,
+  and then call :meth:`~sqlite3.Connection.load_extension` to load a particular shared library.
+  (Updated by Gerhard Häring.)
+
+* The :mod:`ssl` module's :class:`ssl.SSLSocket` objects now support the
+  buffer API, which fixed a test suite failure (fix by Antoine Pitrou;
+  :issue:`7133`) and automatically set
+  OpenSSL's :c:macro:`SSL_MODE_AUTO_RETRY`, which will prevent an error
+  code being returned from :meth:`recv` operations that trigger an SSL
+  renegotiation (fix by Antoine Pitrou; :issue:`8222`).
+
+  The :func:`ssl.wrap_socket` constructor function now takes a
+  *ciphers* argument that's a string listing the encryption algorithms
+  to be allowed; the format of the string is described
+  `in the OpenSSL documentation
+  <http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT>`__.
+  (Added by Antoine Pitrou; :issue:`8322`.)
+
+  Another change makes the extension load all of OpenSSL's ciphers and
+  digest algorithms so that they're all available.  Some SSL
+  certificates couldn't be verified, reporting an "unknown algorithm"
+  error.  (Reported by Beda Kosata, and fixed by Antoine Pitrou;
+  :issue:`8484`.)
+
+  The version of OpenSSL being used is now available as the module
+  attributes :data:`ssl.OPENSSL_VERSION` (a string),
+  :data:`ssl.OPENSSL_VERSION_INFO` (a 5-tuple), and
+  :data:`ssl.OPENSSL_VERSION_NUMBER` (an integer).  (Added by Antoine
+  Pitrou; :issue:`8321`.)
+
+* The :mod:`struct` module will no longer silently ignore overflow
+  errors when a value is too large for a particular integer format
+  code (one of ``bBhHiIlLqQ``); it now always raises a
+  :exc:`struct.error` exception.  (Changed by Mark Dickinson;
+  :issue:`1523`.)  The :func:`~struct.pack` function will also
+  attempt to use :meth:`__index__` to convert and pack non-integers
+  before trying the :meth:`__int__` method or reporting an error.
+  (Changed by Mark Dickinson; :issue:`8300`.)
+
+* New function: the :mod:`subprocess` module's
+  :func:`~subprocess.check_output` runs a command with a specified set of arguments
+  and returns the command's output as a string when the command runs without
+  error, or raises a :exc:`~subprocess.CalledProcessError` exception otherwise.
+
+  ::
+
+    >>> subprocess.check_output(['df', '-h', '.'])
+    'Filesystem     Size   Used  Avail Capacity  Mounted on\n
+    /dev/disk0s2    52G    49G   3.0G    94%    /\n'
+
+    >>> subprocess.check_output(['df', '-h', '/bogus'])
+      ...
+    subprocess.CalledProcessError: Command '['df', '-h', '/bogus']' returned non-zero exit status 1
+
+  (Contributed by Gregory P. Smith.)
+
+  The :mod:`subprocess` module will now retry its internal system calls
+  on receiving an :const:`EINTR` signal.  (Reported by several people; final
+  patch by Gregory P. Smith in :issue:`1068268`.)
+
+* New function: :func:`~symtable.is_declared_global` in the :mod:`symtable` module
+  returns true for variables that are explicitly declared to be global,
+  false for ones that are implicitly global.
+  (Contributed by Jeremy Hylton.)
+
+* The :mod:`syslog` module will now use the value of ``sys.argv[0]`` as the
+  identifier instead of the previous default value of ``'python'``.
+  (Changed by Sean Reifschneider; :issue:`8451`.)
+
+* The ``sys.version_info`` value is now a named tuple, with attributes
+  named :attr:`major`, :attr:`minor`, :attr:`micro`,
+  :attr:`releaselevel`, and :attr:`serial`.  (Contributed by Ross
+  Light; :issue:`4285`.)
+
+  :func:`sys.getwindowsversion` also returns a named tuple,
+  with attributes named :attr:`major`, :attr:`minor`, :attr:`build`,
+  :attr:`platform`, :attr:`service_pack`, :attr:`service_pack_major`,
+  :attr:`service_pack_minor`, :attr:`suite_mask`, and
+  :attr:`product_type`.  (Contributed by Brian Curtin; :issue:`7766`.)
+
+* The :mod:`tarfile` module's default error handling has changed, to
+  no longer suppress fatal errors.  The default error level was previously 0,
+  which meant that errors would only result in a message being written to the
+  debug log, but because the debug log is not activated by default,
+  these errors go unnoticed.  The default error level is now 1,
+  which raises an exception if there's an error.
+  (Changed by Lars Gustäbel; :issue:`7357`.)
+
+  :mod:`tarfile` now supports filtering the :class:`~tarfile.TarInfo`
+  objects being added to a tar file.  When you call :meth:`~tarfile.TarFile.add`,
+  you may supply an optional *filter* argument
+  that's a callable.  The *filter* callable will be passed the
+  :class:`~tarfile.TarInfo` for every file being added, and can modify and return it.
+  If the callable returns ``None``, the file will be excluded from the
+  resulting archive.  This is more powerful than the existing
+  *exclude* argument, which has therefore been deprecated.
+  (Added by Lars Gustäbel; :issue:`6856`.)
+  The :class:`~tarfile.TarFile` class also now supports the context manager protocol.
+  (Added by Lars Gustäbel; :issue:`7232`.)
+
+* The :meth:`~threading.Event.wait` method of the :class:`threading.Event` class
+  now returns the internal flag on exit.  This means the method will usually
+  return true because :meth:`~threading.Event.wait` is supposed to block until the
+  internal flag becomes true.  The return value will only be false if
+  a timeout was provided and the operation timed out.
+  (Contributed by Tim Lesher; :issue:`1674032`.)
+
+* The Unicode database provided by the :mod:`unicodedata` module is
+  now used internally to determine which characters are numeric,
+  whitespace, or represent line breaks.  The database also
+  includes information from the :file:`Unihan.txt` data file (patch
+  by Anders Chrigström and Amaury Forgeot d'Arc; :issue:`1571184`)
+  and has been updated to version 5.2.0 (updated by
+  Florent Xicluna; :issue:`8024`).
+
+* The :mod:`urlparse` module's :func:`~urlparse.urlsplit` now handles
+  unknown URL schemes in a fashion compliant with :rfc:`3986`: if the
+  URL is of the form ``"<something>://..."``, the text before the
+  ``://`` is treated as the scheme, even if it's a made-up scheme that
+  the module doesn't know about.  This change may break code that
+  worked around the old behaviour.  For example, Python 2.6.4 or 2.5
+  will return the following:
+
+    >>> import urlparse
+    >>> urlparse.urlsplit('invented://host/filename?query')
+    ('invented', '', '//host/filename?query', '', '')
+
+  Python 2.7 (and Python 2.6.5) will return:
+
+    >>> import urlparse
+    >>> urlparse.urlsplit('invented://host/filename?query')
+    ('invented', 'host', '/filename?query', '', '')
+
+  (Python 2.7 actually produces slightly different output, since it
+  returns a named tuple instead of a standard tuple.)
+
+  The :mod:`urlparse` module also supports IPv6 literal addresses as defined by
+  :rfc:`2732` (contributed by Senthil Kumaran; :issue:`2987`). ::
+
+    >>> urlparse.urlparse('http://[1080::8:800:200C:417A]/foo')
+    ParseResult(scheme='http', netloc='[1080::8:800:200C:417A]',
+                path='/foo', params='', query='', fragment='')
+
+* New class: the :class:`~weakref.WeakSet` class in the :mod:`weakref`
+  module is a set that only holds weak references to its elements; elements
+  will be removed once there are no references pointing to them.
+  (Originally implemented in Python 3.x by Raymond Hettinger, and backported
+  to 2.7 by Michael Foord.)
+
+* The ElementTree library, :mod:`xml.etree`, no longer escapes
+  ampersands and angle brackets when outputting an XML processing
+  instruction (which looks like ``<?xml-stylesheet href="#style1"?>``)
+  or comment (which looks like ``<!-- comment -->``).
+  (Patch by Neil Muller; :issue:`2746`.)
+
+* The XML-RPC client and server, provided by the :mod:`xmlrpclib` and
+  :mod:`SimpleXMLRPCServer` modules, have improved performance by
+  supporting HTTP/1.1 keep-alive and by optionally using gzip encoding
+  to compress the XML being exchanged.  The gzip compression is
+  controlled by the :attr:`encode_threshold` attribute of
+  :class:`SimpleXMLRPCRequestHandler`, which contains a size in bytes;
+  responses larger than this will be compressed.
+  (Contributed by Kristján Valur Jónsson; :issue:`6267`.)
+
+* The :mod:`zipfile` module's :class:`~zipfile.ZipFile` now supports the context
+  management protocol, so you can write ``with zipfile.ZipFile(...) as f:``.
+  (Contributed by Brian Curtin; :issue:`5511`.)
+
+  :mod:`zipfile` now also supports archiving empty directories and
+  extracts them correctly.  (Fixed by Kuba Wieczorek; :issue:`4710`.)
+  Reading files out of an archive is faster, and interleaving
+  :meth:`~zipfile.ZipFile.read` and :meth:`~zipfile.ZipFile.readline` now works correctly.
+  (Contributed by Nir Aides; :issue:`7610`.)
+
+  The :func:`~zipfile.is_zipfile` function now
+  accepts a file object, in addition to the path names accepted in earlier
+  versions.  (Contributed by Gabriel Genellina; :issue:`4756`.)
+
+  The :meth:`~zipfile.ZipFile.writestr` method now has an optional *compress_type* parameter
+  that lets you override the default compression method specified in the
+  :class:`~zipfile.ZipFile` constructor.  (Contributed by Ronald Oussoren;
+  :issue:`6003`.)
+
+
+.. ======================================================================
+.. whole new modules get described in subsections here
+
+
+.. _importlib-section:
+
+New module: importlib
+------------------------------
+
+Python 3.1 includes the :mod:`importlib` package, a re-implementation
+of the logic underlying Python's :keyword:`import` statement.
+:mod:`importlib` is useful for implementors of Python interpreters and
+to users who wish to write new importers that can participate in the
+import process.  Python 2.7 doesn't contain the complete
+:mod:`importlib` package, but instead has a tiny subset that contains
+a single function, :func:`~importlib.import_module`.
+
+``import_module(name, package=None)`` imports a module.  *name* is
+a string containing the module or package's name.  It's possible to do
+relative imports by providing a string that begins with a ``.``
+character, such as ``..utils.errors``.  For relative imports, the
+*package* argument must be provided and is the name of the package that
+will be used as the anchor for
+the relative import.  :func:`~importlib.import_module` both inserts the imported
+module into ``sys.modules`` and returns the module object.
+
+Here are some examples::
+
+    >>> from importlib import import_module
+    >>> anydbm = import_module('anydbm')  # Standard absolute import
+    >>> anydbm
+    <module 'anydbm' from '/p/python/Lib/anydbm.py'>
+    >>> # Relative import
+    >>> file_util = import_module('..file_util', 'distutils.command')
+    >>> file_util
+    <module 'distutils.file_util' from '/python/Lib/distutils/file_util.pyc'>
+
+:mod:`importlib` was implemented by Brett Cannon and introduced in
+Python 3.1.
+
+
+New module: sysconfig
+---------------------------------
+
+The :mod:`sysconfig` module has been pulled out of the Distutils
+package, becoming a new top-level module in its own right.
+:mod:`sysconfig` provides functions for getting information about
+Python's build process: compiler switches, installation paths, the
+platform name, and whether Python is running from its source
+directory.
+
+Some of the functions in the module are:
+
+* :func:`~sysconfig.get_config_var` returns variables from Python's
+  Makefile and the :file:`pyconfig.h` file.
+* :func:`~sysconfig.get_config_vars` returns a dictionary containing
+  all of the configuration variables.
+* :func:`~sysconfig.getpath` returns the configured path for
+  a particular type of module: the standard library,
+  site-specific modules, platform-specific modules, etc.
+* :func:`~sysconfig.is_python_build` returns true if you're running a
+  binary from a Python source tree, and false otherwise.
+
+Consult the :mod:`sysconfig` documentation for more details and for
+a complete list of functions.
+
+The Distutils package and :mod:`sysconfig` are now maintained by Tarek
+Ziadé, who has also started a Distutils2 package (source repository at
+http://hg.python.org/distutils2/) for developing a next-generation
+version of Distutils.
+
+
+ttk: Themed Widgets for Tk
+--------------------------
+
+Tcl/Tk 8.5 includes a set of themed widgets that re-implement basic Tk
+widgets but have a more customizable appearance and can therefore more
+closely resemble the native platform's widgets.  This widget
+set was originally called Tile, but was renamed to Ttk (for "themed Tk")
+on being added to Tcl/Tck release 8.5.
+
+To learn more, read the :mod:`ttk` module documentation.  You may also
+wish to read the Tcl/Tk manual page describing the
+Ttk theme engine, available at
+http://www.tcl.tk/man/tcl8.5/TkCmd/ttk_intro.htm. Some
+screenshots of the Python/Ttk code in use are at
+http://code.google.com/p/python-ttk/wiki/Screenshots.
+
+The :mod:`ttk` module was written by Guilherme Polo and added in
+:issue:`2983`.  An alternate version called ``Tile.py``, written by
+Martin Franklin and maintained by Kevin Walzer, was proposed for
+inclusion in :issue:`2618`, but the authors argued that Guilherme
+Polo's work was more comprehensive.
+
+
+.. _unittest-section:
+
+Updated module: unittest
+---------------------------------
+
+The :mod:`unittest` module was greatly enhanced; many
+new features were added.  Most of these features were implemented
+by Michael Foord, unless otherwise noted.  The enhanced version of
+the module is downloadable separately for use with Python versions 2.4 to 2.6,
+packaged as the :mod:`unittest2` package, from
+http://pypi.python.org/pypi/unittest2.
+
+When used from the command line, the module can automatically discover
+tests.  It's not as fancy as `py.test <http://pytest.org>`__ or
+`nose <http://code.google.com/p/python-nose/>`__, but provides a simple way
+to run tests kept within a set of package directories.  For example,
+the following command will search the :file:`test/` subdirectory for
+any importable test files named ``test*.py``::
+
+   python -m unittest discover -s test
+
+Consult the :mod:`unittest` module documentation for more details.
+(Developed in :issue:`6001`.)
+
+The :func:`main` function supports some other new options:
+
+* :option:`-b` or :option:`--buffer` will buffer the standard output
+  and standard error streams during each test.  If the test passes,
+  any resulting output will be discarded; on failure, the buffered
+  output will be displayed.
+
+* :option:`-c` or :option:`--catch` will cause the control-C interrupt
+  to be handled more gracefully.  Instead of interrupting the test
+  process immediately, the currently running test will be completed
+  and then the partial results up to the interruption will be reported.
+  If you're impatient, a second press of control-C will cause an immediate
+  interruption.
+
+  This control-C handler tries to avoid causing problems when the code
+  being tested or the tests being run have defined a signal handler of
+  their own, by noticing that a signal handler was already set and
+  calling it.  If this doesn't work for you, there's a
+  :func:`removeHandler` decorator that can be used to mark tests that
+  should have the control-C handling disabled.
+
+* :option:`-f` or :option:`--failfast` makes
+  test execution stop immediately when a test fails instead of
+  continuing to execute further tests.  (Suggested by Cliff Dyer and
+  implemented by Michael Foord; :issue:`8074`.)
+
+The progress messages now show 'x' for expected failures
+and 'u' for unexpected successes when run in verbose mode.
+(Contributed by Benjamin Peterson.)
+
+Test cases can raise the :exc:`~unittest.SkipTest` exception to skip a
+test (:issue:`1034053`).
+
+The error messages for :meth:`~unittest.TestCase.assertEqual`,
+:meth:`~unittest.TestCase.assertTrue`, and :meth:`~unittest.TestCase.assertFalse`
+failures now provide more information.  If you set the
+:attr:`~unittest.TestCase.longMessage` attribute of your :class:`~unittest.TestCase` classes to
+True, both the standard error message and any additional message you
+provide will be printed for failures.  (Added by Michael Foord; :issue:`5663`.)
+
+The :meth:`~unittest.TestCase.assertRaises` method now
+returns a context handler when called without providing a callable
+object to run.  For example, you can write this::
+
+  with self.assertRaises(KeyError):
+      {}['foo']
+
+(Implemented by Antoine Pitrou; :issue:`4444`.)
+
+.. rev 78774
+
+Module- and class-level setup and teardown fixtures are now supported.
+Modules can contain :func:`~unittest.setUpModule` and :func:`~unittest.tearDownModule`
+functions.  Classes can have :meth:`~unittest.TestCase.setUpClass` and
+:meth:`~unittest.TestCase.tearDownClass` methods that must be defined as class methods
+(using ``@classmethod`` or equivalent).  These functions and
+methods are invoked when the test runner switches to a test case in a
+different module or class.
+
+The methods :meth:`~unittest.TestCase.addCleanup` and
+:meth:`~unittest.TestCase.doCleanups` were added.
+:meth:`~unittest.TestCase.addCleanup` lets you add cleanup functions that
+will be called unconditionally (after :meth:`~unittest.TestCase.setUp` if
+:meth:`~unittest.TestCase.setUp` fails, otherwise after :meth:`~unittest.TestCase.tearDown`). This allows
+for much simpler resource allocation and deallocation during tests
+(:issue:`5679`).
+
+A number of new methods were added that provide more specialized
+tests.  Many of these methods were written by Google engineers
+for use in their test suites; Gregory P. Smith, Michael Foord, and
+GvR worked on merging them into Python's version of :mod:`unittest`.
+
+* :meth:`~unittest.TestCase.assertIsNone` and :meth:`~unittest.TestCase.assertIsNotNone` take one
+  expression and verify that the result is or is not ``None``.
+
+* :meth:`~unittest.TestCase.assertIs` and :meth:`~unittest.TestCase.assertIsNot`
+  take two values and check whether the two values evaluate to the same object or not.
+  (Added by Michael Foord; :issue:`2578`.)
+
+* :meth:`~unittest.TestCase.assertIsInstance` and
+  :meth:`~unittest.TestCase.assertNotIsInstance` check whether
+  the resulting object is an instance of a particular class, or of
+  one of a tuple of classes.  (Added by Georg Brandl; :issue:`7031`.)
+
+* :meth:`~unittest.TestCase.assertGreater`, :meth:`~unittest.TestCase.assertGreaterEqual`,
+  :meth:`~unittest.TestCase.assertLess`, and :meth:`~unittest.TestCase.assertLessEqual` compare
+  two quantities.
+
+* :meth:`~unittest.TestCase.assertMultiLineEqual` compares two strings, and if they're
+  not equal, displays a helpful comparison that highlights the
+  differences in the two strings.  This comparison is now used by
+  default when Unicode strings are compared with :meth:`~unittest.TestCase.assertEqual`.
+
+* :meth:`~unittest.TestCase.assertRegexpMatches` and
+  :meth:`~unittest.TestCase.assertNotRegexpMatches` checks whether the
+  first argument is a string matching or not matching the regular
+  expression provided as the second argument (:issue:`8038`).
+
+* :meth:`~unittest.TestCase.assertRaisesRegexp` checks whether a particular exception
+  is raised, and then also checks that the string representation of
+  the exception matches the provided regular expression.
+
+* :meth:`~unittest.TestCase.assertIn` and :meth:`~unittest.TestCase.assertNotIn`
+  tests whether *first* is or is not in  *second*.
+
+* :meth:`~unittest.TestCase.assertItemsEqual` tests whether two provided sequences
+  contain the same elements.
+
+* :meth:`~unittest.TestCase.assertSetEqual` compares whether two sets are equal, and
+  only reports the differences between the sets in case of error.
+
+* Similarly, :meth:`~unittest.TestCase.assertListEqual` and :meth:`~unittest.TestCase.assertTupleEqual`
+  compare the specified types and explain any differences without necessarily
+  printing their full values; these methods are now used by default
+  when comparing lists and tuples using :meth:`~unittest.TestCase.assertEqual`.
+  More generally, :meth:`~unittest.TestCase.assertSequenceEqual` compares two sequences
+  and can optionally check whether both sequences are of a
+  particular type.
+
+* :meth:`~unittest.TestCase.assertDictEqual` compares two dictionaries and reports the
+  differences; it's now used by default when you compare two dictionaries
+  using :meth:`~unittest.TestCase.assertEqual`.  :meth:`~unittest.TestCase.assertDictContainsSubset` checks whether
+  all of the key/value pairs in *first* are found in *second*.
+
+* :meth:`~unittest.TestCase.assertAlmostEqual` and :meth:`~unittest.TestCase.assertNotAlmostEqual` test
+  whether *first* and *second* are approximately equal.  This method
+  can either round their difference to an optionally-specified number
+  of *places* (the default is 7) and compare it to zero, or require
+  the difference to be smaller than a supplied *delta* value.
+
+* :meth:`~unittest.TestLoader.loadTestsFromName` properly honors the
+  :attr:`~unittest.TestLoader.suiteClass` attribute of
+  the :class:`~unittest.TestLoader`. (Fixed by Mark Roddy; :issue:`6866`.)
+
+* A new hook lets you extend the :meth:`~unittest.TestCase.assertEqual` method to handle
+  new data types.  The :meth:`~unittest.TestCase.addTypeEqualityFunc` method takes a type
+  object and a function. The function will be used when both of the
+  objects being compared are of the specified type.  This function
+  should compare the two objects and raise an exception if they don't
+  match; it's a good idea for the function to provide additional
+  information about why the two objects aren't matching, much as the new
+  sequence comparison methods do.
+
+:func:`unittest.main` now takes an optional ``exit`` argument.  If
+False, :func:`~unittest.main` doesn't call :func:`sys.exit`, allowing
+:func:`main` to be used from the interactive interpreter.
+(Contributed by J. Pablo Fernández; :issue:`3379`.)
+
+:class:`~unittest.TestResult` has new :meth:`~unittest.TestResult.startTestRun` and
+:meth:`~unittest.TestResult.stopTestRun` methods that are called immediately before
+and after a test run.  (Contributed by Robert Collins; :issue:`5728`.)
+
+With all these changes, the :file:`unittest.py` was becoming awkwardly
+large, so the module was turned into a package and the code split into
+several files (by Benjamin Peterson).  This doesn't affect how the
+module is imported or used.

+
+Updated module: ElementTree 1.3
+---------------------------------
+
+The version of the ElementTree library included with Python was updated to
+version 1.3.  Some of the new features are:
+
+* The various parsing functions now take a *parser* keyword argument
+  giving an :class:`XMLParser` instance that will
+  be used.  This makes it possible to override the file's internal encoding::
+
+    p = ET.XMLParser(encoding='utf-8')
+    t = ET.XML("""<root/>""", parser=p)
+
+  Errors in parsing XML now raise a :exc:`ParseError` exception, whose
+  instances have a :attr:`position` attribute
+  containing a (*line*, *column*) tuple giving the location of the problem.
+
+* ElementTree's code for converting trees to a string has been
+  significantly reworked, making it roughly twice as fast in many
+  cases.  The :class:`ElementTree` :meth:`write` and :class:`Element`
+  :meth:`write` methods now have a *method* parameter that can be
+  "xml" (the default), "html", or "text".  HTML mode will output empty
+  elements as ``<empty></empty>`` instead of ``<empty/>``, and text
+  mode will skip over elements and only output the text chunks.  If
+  you set the :attr:`tag` attribute of an element to ``None`` but
+  leave its children in place, the element will be omitted when the
+  tree is written out, so you don't need to do more extensive rearrangement
+  to remove a single element.
+
+  Namespace handling has also been improved.  All ``xmlns:<whatever>``
+  declarations are now output on the root element, not scattered throughout
+  the resulting XML.  You can set the default namespace for a tree
+  by setting the :attr:`default_namespace` attribute and can
+  register new prefixes with :meth:`register_namespace`.  In XML mode,
+  you can use the true/false *xml_declaration* parameter to suppress the
+  XML declaration.
+
+* New :class:`Element` method: :meth:`extend` appends the items from a
+  sequence to the element's children.  Elements themselves behave like
+  sequences, so it's easy to move children from one element to
+  another::
+
+    from xml.etree import ElementTree as ET
+
+    t = ET.XML("""<list>
+      <item>1</item> <item>2</item>  <item>3</item>
+    </list>""")
+    new = ET.XML('<root/>')
+    new.extend(t)
+
+    # Outputs <root><item>1</item>...</root>
+    print ET.tostring(new)
+
+* New :class:`Element` method: :meth:`iter` yields the children of the
+  element as a generator.  It's also possible to write ``for child in
+  elem:`` to loop over an element's children.  The existing method
+  :meth:`getiterator` is now deprecated, as is :meth:`getchildren`
+  which constructs and returns a list of children.
+
+* New :class:`Element` method: :meth:`itertext` yields all chunks of
+  text that are descendants of the element.  For example::
+
+    t = ET.XML("""<list>
+      <item>1</item> <item>2</item>  <item>3</item>
+    </list>""")
+
+    # Outputs ['\n  ', '1', ' ', '2', '  ', '3', '\n']
+    print list(t.itertext())
+
+* Deprecated: using an element as a Boolean (i.e., ``if elem:``) would
+  return true if the element had any children, or false if there were
+  no children.  This behaviour is confusing -- ``None`` is false, but
+  so is a childless element? -- so it will now trigger a
+  :exc:`FutureWarning`.  In your code, you should be explicit: write
+  ``len(elem) != 0`` if you're interested in the number of children,
+  or ``elem is not None``.
+
+Fredrik Lundh develops ElementTree and produced the 1.3 version;
+you can read his article describing 1.3 at
+http://effbot.org/zone/elementtree-13-intro.htm.
+Florent Xicluna updated the version included with
+Python, after discussions on python-dev and in :issue:`6472`.)
+
+.. ======================================================================
+
+
+Build and C API Changes
+=======================
+
+Changes to Python's build process and to the C API include:
+
+* The latest release of the GNU Debugger, GDB 7, can be `scripted
+  using Python
+  <http://sourceware.org/gdb/current/onlinedocs/gdb/Python.html>`__.
+  When you begin debugging an executable program P, GDB will look for
+  a file named ``P-gdb.py`` and automatically read it.  Dave Malcolm
+  contributed a :file:`python-gdb.py` that adds a number of
+  commands useful when debugging Python itself.  For example,
+  ``py-up`` and ``py-down`` go up or down one Python stack frame,
+  which usually corresponds to several C stack frames.  ``py-print``
+  prints the value of a Python variable, and ``py-bt`` prints the
+  Python stack trace.  (Added as a result of :issue:`8032`.)
+
+* If you use the :file:`.gdbinit` file provided with Python,
+  the "pyo" macro in the 2.7 version now works correctly when the thread being
+  debugged doesn't hold the GIL; the macro now acquires it before printing.
+  (Contributed by Victor Stinner; :issue:`3632`.)
+
+* :c:func:`Py_AddPendingCall` is now thread-safe, letting any
+  worker thread submit notifications to the main Python thread.  This
+  is particularly useful for asynchronous IO operations.
+  (Contributed by Kristján Valur Jónsson; :issue:`4293`.)
+
+* New function: :c:func:`PyCode_NewEmpty` creates an empty code object;
+  only the filename, function name, and first line number are required.
+  This is useful for extension modules that are attempting to
+  construct a more useful traceback stack.  Previously such
+  extensions needed to call :c:func:`PyCode_New`, which had many
+  more arguments.  (Added by Jeffrey Yasskin.)
+
+* New function: :c:func:`PyErr_NewExceptionWithDoc` creates a new
+  exception class, just as the existing :c:func:`PyErr_NewException` does,
+  but takes an extra ``char *`` argument containing the docstring for the
+  new exception class.  (Added by 'lekma' on the Python bug tracker;
+  :issue:`7033`.)
+
+* New function: :c:func:`PyFrame_GetLineNumber` takes a frame object
+  and returns the line number that the frame is currently executing.
+  Previously code would need to get the index of the bytecode
+  instruction currently executing, and then look up the line number
+  corresponding to that address.  (Added by Jeffrey Yasskin.)
+
+* New functions: :c:func:`PyLong_AsLongAndOverflow` and
+  :c:func:`PyLong_AsLongLongAndOverflow`  approximates a Python long
+  integer as a C :c:type:`long` or :c:type:`long long`.
+  If the number is too large to fit into
+  the output type, an *overflow* flag is set and returned to the caller.
+  (Contributed by Case Van Horsen; :issue:`7528` and :issue:`7767`.)
+
+* New function: stemming from the rewrite of string-to-float conversion,
+  a new :c:func:`PyOS_string_to_double` function was added.  The old
+  :c:func:`PyOS_ascii_strtod` and :c:func:`PyOS_ascii_atof` functions
+  are now deprecated.
+
+* New function: :c:func:`PySys_SetArgvEx` sets the value of
+  ``sys.argv`` and can optionally update ``sys.path`` to include the
+  directory containing the script named by ``sys.argv[0]`` depending
+  on the value of an *updatepath* parameter.
+
+  This function was added to close a security hole for applications
+  that embed Python.  The old function, :c:func:`PySys_SetArgv`, would
+  always update ``sys.path``, and sometimes it would add the current
+  directory.  This meant that, if you ran an application embedding
+  Python in a directory controlled by someone else, attackers could
+  put a Trojan-horse module in the directory (say, a file named
+  :file:`os.py`) that your application would then import and run.
+
+  If you maintain a C/C++ application that embeds Python, check
+  whether you're calling :c:func:`PySys_SetArgv` and carefully consider
+  whether the application should be using :c:func:`PySys_SetArgvEx`
+  with *updatepath* set to false.
+
+  Security issue reported as `CVE-2008-5983
+  <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_;
+  discussed in :issue:`5753`, and fixed by Antoine Pitrou.
+
+* New macros: the Python header files now define the following macros:
+  :c:macro:`Py_ISALNUM`,
+  :c:macro:`Py_ISALPHA`,
+  :c:macro:`Py_ISDIGIT`,
+  :c:macro:`Py_ISLOWER`,
+  :c:macro:`Py_ISSPACE`,
+  :c:macro:`Py_ISUPPER`,
+  :c:macro:`Py_ISXDIGIT`,
+  and :c:macro:`Py_TOLOWER`, :c:macro:`Py_TOUPPER`.
+  All of these functions are analogous to the C
+  standard macros for classifying characters, but ignore the current
+  locale setting, because in
+  several places Python needs to analyze characters in a
+  locale-independent way.  (Added by Eric Smith;
+  :issue:`5793`.)
+
+  .. XXX these macros don't seem to be described in the c-api docs.
+
+* Removed function: :c:macro:`PyEval_CallObject` is now only available
+  as a macro.  A function version was being kept around to preserve
+  ABI linking compatibility, but that was in 1997; it can certainly be
+  deleted by now.  (Removed by Antoine Pitrou; :issue:`8276`.)
+
+* New format codes: the :c:func:`PyFormat_FromString`,
+  :c:func:`PyFormat_FromStringV`, and :c:func:`PyErr_Format` functions now
+  accept ``%lld`` and ``%llu`` format codes for displaying
+  C's :c:type:`long long` types.
+  (Contributed by Mark Dickinson; :issue:`7228`.)
+
+* The complicated interaction between threads and process forking has
+  been changed.  Previously, the child process created by
+  :func:`os.fork` might fail because the child is created with only a
+  single thread running, the thread performing the :func:`os.fork`.
+  If other threads were holding a lock, such as Python's import lock,
+  when the fork was performed, the lock would still be marked as
+  "held" in the new process.  But in the child process nothing would
+  ever release the lock, since the other threads weren't replicated,
+  and the child process would no longer be able to perform imports.
+
+  Python 2.7 acquires the import lock before performing an
+  :func:`os.fork`, and will also clean up any locks created using the
+  :mod:`threading` module.  C extension modules that have internal
+  locks, or that call :c:func:`fork()` themselves, will not benefit
+  from this clean-up.
+
+  (Fixed by Thomas Wouters; :issue:`1590864`.)
+
+* The :c:func:`Py_Finalize` function now calls the internal
+  :func:`threading._shutdown` function; this prevents some exceptions from
+  being raised when an interpreter shuts down.
+  (Patch by Adam Olsen; :issue:`1722344`.)
+
+* When using the :c:type:`PyMemberDef` structure to define attributes
+  of a type, Python will no longer let you try to delete or set a
+  :const:`T_STRING_INPLACE` attribute.
+
+  .. rev 79644
+
+* Global symbols defined by the :mod:`ctypes` module are now prefixed
+  with ``Py``, or with ``_ctypes``.  (Implemented by Thomas
+  Heller; :issue:`3102`.)
+
+* New configure option: the :option:`--with-system-expat` switch allows
+  building the :mod:`pyexpat` module to use the system Expat library.
+  (Contributed by Arfrever Frehtes Taifersar Arahesis; :issue:`7609`.)
+
+* New configure option: the
+  :option:`--with-valgrind` option will now disable the pymalloc
+  allocator, which is difficult for the Valgrind memory-error detector
+  to analyze correctly.
+  Valgrind will therefore be better at detecting memory leaks and
+  overruns. (Contributed by James Henstridge; :issue:`2422`.)
+
+* New configure option: you can now supply an empty string to
+  :option:`--with-dbmliborder=` in order to disable all of the various
+  DBM modules.  (Added by Arfrever Frehtes Taifersar Arahesis;
+  :issue:`6491`.)
+
+* The :program:`configure` script now checks for floating-point rounding bugs
+  on certain 32-bit Intel chips and defines a :c:macro:`X87_DOUBLE_ROUNDING`
+  preprocessor definition.  No code currently uses this definition,
+  but it's available if anyone wishes to use it.
+  (Added by Mark Dickinson; :issue:`2937`.)
+
+  :program:`configure` also now sets a :envvar:`LDCXXSHARED` Makefile
+  variable for supporting C++ linking.  (Contributed by Arfrever
+  Frehtes Taifersar Arahesis; :issue:`1222585`.)
+
+* The build process now creates the necessary files for pkg-config
+  support.  (Contributed by Clinton Roy; :issue:`3585`.)
+
+* The build process now supports Subversion 1.7.  (Contributed by
+  Arfrever Frehtes Taifersar Arahesis; :issue:`6094`.)
+
+
+.. _whatsnew27-capsules:
+
+Capsules
+-------------------
+
+Python 3.1 adds a new C datatype, :c:type:`PyCapsule`, for providing a
+C API to an extension module.  A capsule is essentially the holder of
+a C ``void *`` pointer, and is made available as a module attribute; for
+example, the :mod:`socket` module's API is exposed as ``socket.CAPI``,
+and :mod:`unicodedata` exposes ``ucnhash_CAPI``.  Other extensions
+can import the module, access its dictionary to get the capsule
+object, and then get the ``void *`` pointer, which will usually point
+to an array of pointers to the module's various API functions.
+
+There is an existing data type already used for this,
+:c:type:`PyCObject`, but it doesn't provide type safety.  Evil code
+written in pure Python could cause a segmentation fault by taking a
+:c:type:`PyCObject` from module A and somehow substituting it for the
+:c:type:`PyCObject` in module B.   Capsules know their own name,
+and getting the pointer requires providing the name::
+
+   void *vtable;
+
+   if (!PyCapsule_IsValid(capsule, "mymodule.CAPI") {
+           PyErr_SetString(PyExc_ValueError, "argument type invalid");
+           return NULL;
+   }
+
+   vtable = PyCapsule_GetPointer(capsule, "mymodule.CAPI");
+
+You are assured that ``vtable`` points to whatever you're expecting.
+If a different capsule was passed in, :c:func:`PyCapsule_IsValid` would
+detect the mismatched name and return false.  Refer to
+:ref:`using-capsules` for more information on using these objects.
+
+Python 2.7 now uses capsules internally to provide various
+extension-module APIs, but the :c:func:`PyCObject_AsVoidPtr` was
+modified to handle capsules, preserving compile-time compatibility
+with the :c:type:`CObject` interface.  Use of
+:c:func:`PyCObject_AsVoidPtr` will signal a
+:exc:`PendingDeprecationWarning`, which is silent by default.
+
+Implemented in Python 3.1 and backported to 2.7 by Larry Hastings;
+discussed in :issue:`5630`.
+
+
+.. ======================================================================
+
+Port-Specific Changes: Windows
+-----------------------------------
+
+* The :mod:`msvcrt` module now contains some constants from
+  the :file:`crtassem.h` header file:
+  :data:`CRT_ASSEMBLY_VERSION`,
+  :data:`VC_ASSEMBLY_PUBLICKEYTOKEN`,
+  and :data:`LIBRARIES_ASSEMBLY_NAME_PREFIX`.
+  (Contributed by David Cournapeau; :issue:`4365`.)
+
+* The :mod:`_winreg` module for accessing the registry now implements
+  the :func:`CreateKeyEx` and :func:`DeleteKeyEx` functions, extended
+  versions of previously-supported functions that take several extra
+  arguments.  The :func:`DisableReflectionKey`,
+  :func:`EnableReflectionKey`, and :func:`QueryReflectionKey` were also
+  tested and documented.
+  (Implemented by Brian Curtin: :issue:`7347`.)
+
+* The new :c:func:`_beginthreadex` API is used to start threads, and
+  the native thread-local storage functions are now used.
+  (Contributed by Kristján Valur Jónsson; :issue:`3582`.)
+
+* The :func:`os.kill` function now works on Windows.  The signal value
+  can be the constants :const:`CTRL_C_EVENT`,
+  :const:`CTRL_BREAK_EVENT`, or any integer.  The first two constants
+  will send Control-C and Control-Break keystroke events to
+  subprocesses; any other value will use the :c:func:`TerminateProcess`
+  API.  (Contributed by Miki Tebeka; :issue:`1220212`.)
+
+* The :func:`os.listdir` function now correctly fails
+  for an empty path.  (Fixed by Hirokazu Yamamoto; :issue:`5913`.)
+
+* The :mod:`mimelib` module will now read the MIME database from
+  the Windows registry when initializing.
+  (Patch by Gabriel Genellina; :issue:`4969`.)
+
+.. ======================================================================
+
+Port-Specific Changes: Mac OS X
+-----------------------------------
+
+* The path ``/Library/Python/2.7/site-packages`` is now appended to
+  ``sys.path``, in order to share added packages between the system
+  installation and a user-installed copy of the same version.
+  (Changed by Ronald Oussoren; :issue:`4865`.)
+
+Port-Specific Changes: FreeBSD
+-----------------------------------
+
+* FreeBSD 7.1's :const:`SO_SETFIB` constant, used with
+  :func:`~socket.getsockopt`/:func:`~socket.setsockopt` to select an
+  alternate routing table, is now available in the :mod:`socket`
+  module.  (Added by Kyle VanderBeek; :issue:`8235`.)
+
+Other Changes and Fixes
+=======================
+
+* Two benchmark scripts, :file:`iobench` and :file:`ccbench`, were
+  added to the :file:`Tools` directory.  :file:`iobench` measures the
+  speed of the built-in file I/O objects returned by :func:`open`
+  while performing various operations, and :file:`ccbench` is a
+  concurrency benchmark that tries to measure computing throughput,
+  thread switching latency, and IO processing bandwidth when
+  performing several tasks using a varying number of threads.
+
+* The :file:`Tools/i18n/msgfmt.py` script now understands plural
+  forms in :file:`.po` files.  (Fixed by Martin von Löwis;
+  :issue:`5464`.)
+
+* When importing a module from a :file:`.pyc` or :file:`.pyo` file
+  with an existing :file:`.py` counterpart, the :attr:`co_filename`
+  attributes of the resulting code objects are overwritten when the
+  original filename is obsolete.  This can happen if the file has been
+  renamed, moved, or is accessed through different paths.  (Patch by
+  Ziga Seilnacht and Jean-Paul Calderone; :issue:`1180193`.)
+
+* The :file:`regrtest.py` script now takes a :option:`--randseed=`
+  switch that takes an integer that will be used as the random seed
+  for the :option:`-r` option that executes tests in random order.
+  The :option:`-r` option also reports the seed that was used
+  (Added by Collin Winter.)
+
+* Another :file:`regrtest.py` switch is :option:`-j`, which
+  takes an integer specifying how many tests run in parallel. This
+  allows reducing the total runtime on multi-core machines.
+  This option is compatible with several other options, including the
+  :option:`-R` switch which is known to produce long runtimes.
+  (Added by Antoine Pitrou, :issue:`6152`.)  This can also be used
+  with a new :option:`-F` switch that runs selected tests in a loop
+  until they fail.  (Added by Antoine Pitrou; :issue:`7312`.)
+
+* When executed as a script, the :file:`py_compile.py` module now
+  accepts ``'-'`` as an argument, which will read standard input for
+  the list of filenames to be compiled.  (Contributed by Piotr
+  Ożarowski; :issue:`8233`.)
+
+.. ======================================================================
+
+Porting to Python 2.7
+=====================
+
+This section lists previously described changes and other bugfixes
+that may require changes to your code:
+
+* The :func:`range` function processes its arguments more
+  consistently; it will now call :meth:`__int__` on non-float,
+  non-integer arguments that are supplied to it.  (Fixed by Alexander
+  Belopolsky; :issue:`1533`.)
+
+* The string :meth:`format` method changed the default precision used
+  for floating-point and complex numbers from 6 decimal
+  places to 12, which matches the precision used by :func:`str`.
+  (Changed by Eric Smith; :issue:`5920`.)
+
+* Because of an optimization for the :keyword:`with` statement, the special
+  methods :meth:`__enter__` and :meth:`__exit__` must belong to the object's
+  type, and cannot be directly attached to the object's instance.  This
+  affects new-style classes (derived from :class:`object`) and C extension
+  types.  (:issue:`6101`.)
+
+* Due to a bug in Python 2.6, the *exc_value* parameter to
+  :meth:`__exit__` methods was often the string representation of the
+  exception, not an instance.  This was fixed in 2.7, so *exc_value*
+  will be an instance as expected.  (Fixed by Florent Xicluna;
+  :issue:`7853`.)
+
+* When a restricted set of attributes were set using ``__slots__``,
+  deleting an unset attribute would not raise :exc:`AttributeError`
+  as you would expect.  Fixed by Benjamin Peterson; :issue:`7604`.)
+
+In the standard library:
+
+* Operations with :class:`datetime` instances that resulted in a year
+  falling outside the supported range didn't always raise
+  :exc:`OverflowError`.  Such errors are now checked more carefully
+  and will now raise the exception. (Reported by Mark Leander, patch
+  by Anand B. Pillai and Alexander Belopolsky; :issue:`7150`.)
+
+* When using :class:`Decimal` instances with a string's
+  :meth:`format` method, the default alignment was previously
+  left-alignment.  This has been changed to right-alignment, which might
+  change the output of your programs.
+  (Changed by Mark Dickinson; :issue:`6857`.)
+
+  Comparisons involving a signaling NaN value (or ``sNAN``) now signal
+  :const:`InvalidOperation` instead of silently returning a true or
+  false value depending on the comparison operator.  Quiet NaN values
+  (or ``NaN``) are now hashable.  (Fixed by Mark Dickinson;
+  :issue:`7279`.)
+
+* The ElementTree library, :mod:`xml.etree`, no longer escapes
+  ampersands and angle brackets when outputting an XML processing
+  instruction (which looks like `<?xml-stylesheet href="#style1"?>`)
+  or comment (which looks like `<!-- comment -->`).
+  (Patch by Neil Muller; :issue:`2746`.)
+
+* The :meth:`readline` method of :class:`StringIO` objects now does
+  nothing when a negative length is requested, as other file-like
+  objects do.  (:issue:`7348`).
+
+* The :mod:`syslog` module will now use the value of ``sys.argv[0]`` as the
+  identifier instead of the previous default value of ``'python'``.
+  (Changed by Sean Reifschneider; :issue:`8451`.)
+
+* The :mod:`tarfile` module's default error handling has changed, to
+  no longer suppress fatal errors.  The default error level was previously 0,
+  which meant that errors would only result in a message being written to the
+  debug log, but because the debug log is not activated by default,
+  these errors go unnoticed.  The default error level is now 1,
+  which raises an exception if there's an error.
+  (Changed by Lars Gustäbel; :issue:`7357`.)
+
+* The :mod:`urlparse` module's :func:`~urlparse.urlsplit` now handles
+  unknown URL schemes in a fashion compliant with :rfc:`3986`: if the
+  URL is of the form ``"<something>://..."``, the text before the
+  ``://`` is treated as the scheme, even if it's a made-up scheme that
+  the module doesn't know about.  This change may break code that
+  worked around the old behaviour.  For example, Python 2.6.4 or 2.5
+  will return the following:
+
+    >>> import urlparse
+    >>> urlparse.urlsplit('invented://host/filename?query')
+    ('invented', '', '//host/filename?query', '', '')
+
+  Python 2.7 (and Python 2.6.5) will return:
+
+    >>> import urlparse
+    >>> urlparse.urlsplit('invented://host/filename?query')
+    ('invented', 'host', '/filename?query', '', '')
+
+  (Python 2.7 actually produces slightly different output, since it
+  returns a named tuple instead of a standard tuple.)
+
+For C extensions:
+
+* C extensions that use integer format codes with the ``PyArg_Parse*``
+  family of functions will now raise a :exc:`TypeError` exception
+  instead of triggering a :exc:`DeprecationWarning` (:issue:`5080`).
+
+* Use the new :c:func:`PyOS_string_to_double` function instead of the old
+  :c:func:`PyOS_ascii_strtod` and :c:func:`PyOS_ascii_atof` functions,
+  which are now deprecated.
+
+For applications that embed Python:
+
+* The :c:func:`PySys_SetArgvEx` function was added, letting
+  applications close a security hole when the existing
+  :c:func:`PySys_SetArgv` function was used.  Check whether you're
+  calling :c:func:`PySys_SetArgv` and carefully consider whether the
+  application should be using :c:func:`PySys_SetArgvEx` with
+  *updatepath* set to false.

+PEP 384: Defining a Stable ABI
+==============================
+
+In the past, extension modules built for one Python version were often
+not usable with other Python versions. Particularly on Windows, every
+feature release of Python required rebuilding all extension modules that
+one wanted to use. This requirement was the result of the free access to
+Python interpreter internals that extension modules could use.
+
+With Python 3.2, an alternative approach becomes available: extension
+modules which restrict themselves to a limited API (by defining
+Py_LIMITED_API) cannot use many of the internals, but are constrained
+to a set of API functions that are promised to be stable for several
+releases. As a consequence, extension modules built for 3.2 in that
+mode will also work with 3.3, 3.4, and so on. Extension modules that
+make use of details of memory structures can still be built, but will
+need to be recompiled for every feature release.

+      PEP written by Martin von Löwis.
+
+
+PEP 389: Argparse Command Line Parsing Module
+=============================================
+
+A new module for command line parsing, :mod:`argparse`, was introduced to
+overcome the limitations of :mod:`optparse` which did not provide support for
+positional arguments (not just options), subcommands, required options and other
+common patterns of specifying and validating options.
+
+This module has already had widespread success in the community as a
+third-party module.  Being more fully featured than its predecessor, the
+:mod:`argparse` module is now the preferred module for command-line processing.
+The older module is still being kept available because of the substantial amount
+of legacy code that depends on it.
+
+Here's an annotated example parser showing features like limiting results to a
+set of choices, specifying a *metavar* in the help screen, validating that one
+or more positional arguments is present, and making a required option::
+
+    import argparse
+    parser = argparse.ArgumentParser(
+                description = 'Manage servers',         # main description for help
+                epilog = 'Tested on Solaris and Linux') # displayed after help
+    parser.add_argument('action',                       # argument name
+                choices = ['deploy', 'start', 'stop'],  # three allowed values
+                help = 'action on each target')         # help msg
+    parser.add_argument('targets',
+                metavar = 'HOSTNAME',                   # var name used in help msg
+                nargs = '+',                            # require one or more targets
+                help = 'url for target machines')       # help msg explanation
+    parser.add_argument('-u', '--user',                 # -u or --user option
+                required = True,                        # make it a required argument
+                help = 'login as user')
+
+Example of calling the parser on a command string::
+
+    >>> cmd  = 'deploy sneezy.example.com sleepy.example.com -u skycaptain'
+    >>> result = parser.parse_args(cmd.split())
+    >>> result.action
+    'deploy'
+    >>> result.targets
+    ['sneezy.example.com', 'sleepy.example.com']
+    >>> result.user
+    'skycaptain'
+
+Example of the parser's automatically generated help::
+
+    >>> parser.parse_args('-h'.split())
+
+    usage: manage_cloud.py [-h] -u USER
+                           {deploy,start,stop} HOSTNAME [HOSTNAME ...]
+
+    Manage servers
+
+    positional arguments:
+      {deploy,start,stop}   action on each target
+      HOSTNAME              url for target machines
+
+    optional arguments:
+      -h, --help            show this help message and exit
+      -u USER, --user USER  login as user
+
+    Tested on Solaris and Linux
+
+An especially nice :mod:`argparse` feature is the ability to define subparsers,
+each with their own argument patterns and help displays::
+
+    import argparse
+    parser = argparse.ArgumentParser(prog='HELM')
+    subparsers = parser.add_subparsers()
+
+    parser_l = subparsers.add_parser('launch', help='Launch Control')   # first subgroup
+    parser_l.add_argument('-m', '--missiles', action='store_true')
+    parser_l.add_argument('-t', '--torpedos', action='store_true')
+
+    parser_m = subparsers.add_parser('move', help='Move Vessel',        # second subgroup
+                                     aliases=('steer', 'turn'))         # equivalent names
+    parser_m.add_argument('-c', '--course', type=int, required=True)
+    parser_m.add_argument('-s', '--speed', type=int, default=0)

+
+
+PEP 391:  Dictionary Based Configuration for Logging
+====================================================
+
+The :mod:`logging` module provided two kinds of configuration, one style with
+function calls for each option or another style driven by an external file saved
+in a :mod:`ConfigParser` format.  Those options did not provide the flexibility
+to create configurations from JSON or YAML files, nor did they support
+incremental configuration, which is needed for specifying logger options from a
+command line.
+
+To support a more flexible style, the module now offers
+:func:`logging.config.dictConfig` for specifying logging configuration with
+plain Python dictionaries.  The configuration options include formatters,
+handlers, filters, and loggers.  Here's a working example of a configuration
+dictionary::
+
+   {"version": 1,
+    "formatters": {"brief": {"format": "%(levelname)-8s: %(name)-15s: %(message)s"},
+                   "full": {"format": "%(asctime)s %(name)-15s %(levelname)-8s %(message)s"}
+                   },
+    "handlers": {"console": {
+                      "class": "logging.StreamHandler",
+                      "formatter": "brief",
+                      "level": "INFO",
+                      "stream": "ext://sys.stdout"},
+                 "console_priority": {
+                      "class": "logging.StreamHandler",
+                      "formatter": "full",
+                      "level": "ERROR",
+                      "stream": "ext://sys.stderr"}
+                 },
+    "root": {"level": "DEBUG", "handlers": ["console", "console_priority"]}}
+
+
+If that dictionary is stored in a file called :file:`conf.json`, it can be
+loaded and called with code like this::
+
+   >>> import json, logging.config
+   >>> with open('conf.json') as f:
+           conf = json.load(f)
+   >>> logging.config.dictConfig(conf)
+   >>> logging.info("Transaction completed normally")
+   INFO    : root           : Transaction completed normally
+   >>> logging.critical("Abnormal termination")
+   2011-02-17 11:14:36,694 root            CRITICAL Abnormal termination

+
+
+PEP 3148:  The ``concurrent.futures`` module
+============================================
+
+Code for creating and managing concurrency is being collected in a new top-level
+namespace, *concurrent*.  Its first member is a *futures* package which provides
+a uniform high-level interface for managing threads and processes.
+
+The design for :mod:`concurrent.futures` was inspired by
+*java.util.concurrent.package*.  In that model, a running call and its result
+are represented by a :class:`~concurrent.futures.Future` object that abstracts
+features common to threads, processes, and remote procedure calls.  That object
+supports status checks (running or done), timeouts, cancellations, adding
+callbacks, and access to results or exceptions.
+
+The primary offering of the new module is a pair of executor classes for
+launching and managing calls.  The goal of the executors is to make it easier to
+use existing tools for making parallel calls. They save the effort needed to
+setup a pool of resources, launch the calls, create a results queue, add
+time-out handling, and limit the total number of threads, processes, or remote
+procedure calls.
+
+Ideally, each application should share a single executor across multiple
+components so that process and thread limits can be centrally managed.  This
+solves the design challenge that arises when each component has its own
+competing strategy for resource management.
+
+Both classes share a common interface with three methods:
+:meth:`~concurrent.futures.Executor.submit` for scheduling a callable and
+returning a :class:`~concurrent.futures.Future` object;
+:meth:`~concurrent.futures.Executor.map` for scheduling many asynchronous calls
+at a time, and :meth:`~concurrent.futures.Executor.shutdown` for freeing
+resources.  The class is a :term:`context manager` and can be used in a
+:keyword:`with` statement to assure that resources are automatically released
+when currently pending futures are done executing.
+
+A simple of example of :class:`~concurrent.futures.ThreadPoolExecutor` is a
+launch of four parallel threads for copying files::
+
+  import concurrent.futures, shutil
+  with concurrent.futures.ThreadPoolExecutor(max_workers=4) as e:
+      e.submit(shutil.copy, 'src1.txt', 'dest1.txt')
+      e.submit(shutil.copy, 'src2.txt', 'dest2.txt')
+      e.submit(shutil.copy, 'src3.txt', 'dest3.txt')
+      e.submit(shutil.copy, 'src4.txt', 'dest4.txt')

+PEP 3147:  PYC Repository Directories
+=====================================
+
+Python's scheme for caching bytecode in *.pyc* files did not work well in
+environments with multiple Python interpreters.  If one interpreter encountered
+a cached file created by another interpreter, it would recompile the source and
+overwrite the cached file, thus losing the benefits of caching.
+
+The issue of "pyc fights" has become more pronounced as it has become
+commonplace for Linux distributions to ship with multiple versions of Python.
+These conflicts also arise with CPython alternatives such as Unladen Swallow.
+
+To solve this problem, Python's import machinery has been extended to use
+distinct filenames for each interpreter.  Instead of Python 3.2 and Python 3.3 and
+Unladen Swallow each competing for a file called "mymodule.pyc", they will now
+look for "mymodule.cpython-32.pyc", "mymodule.cpython-33.pyc", and
+"mymodule.unladen10.pyc".  And to prevent all of these new files from
+cluttering source directories, the *pyc* files are now collected in a
+"__pycache__" directory stored under the package directory.
+
+Aside from the filenames and target directories, the new scheme has a few
+aspects that are visible to the programmer:
+
+* Imported modules now have a :attr:`__cached__` attribute which stores the name
+  of the actual file that was imported:
+
+   >>> import collections
+   >>> collections.__cached__
+   'c:/py32/lib/__pycache__/collections.cpython-32.pyc'
+
+* The tag that is unique to each interpreter is accessible from the :mod:`imp`
+  module:
+
+   >>> import imp
+   >>> imp.get_tag()
+   'cpython-32'
+
+* Scripts that try to deduce source filename from the imported file now need to
+  be smarter.  It is no longer sufficient to simply strip the "c" from a ".pyc"
+  filename.  Instead, use the new functions in the :mod:`imp` module:
+
+  >>> imp.source_from_cache('c:/py32/lib/__pycache__/collections.cpython-32.pyc')
+  'c:/py32/lib/collections.py'
+  >>> imp.cache_from_source('c:/py32/lib/collections.py')
+  'c:/py32/lib/__pycache__/collections.cpython-32.pyc'
+
+* The :mod:`py_compile` and :mod:`compileall` modules have been updated to
+  reflect the new naming convention and target directory.  The command-line
+  invocation of *compileall* has new options: ``-i`` for
+  specifying a list of files and directories to compile and ``-b`` which causes
+  bytecode files to be written to their legacy location rather than
+  *__pycache__*.
+
+* The :mod:`importlib.abc` module has been updated with new :term:`abstract base
+  classes <abstract base class>` for loading bytecode files.  The obsolete
+  ABCs, :class:`~importlib.abc.PyLoader` and
+  :class:`~importlib.abc.PyPycLoader`, have been deprecated (instructions on how
+  to stay Python 3.1 compatible are included with the documentation).

+      PEP written by Barry Warsaw.
+
+
+PEP 3149: ABI Version Tagged .so Files
+======================================
+
+The PYC repository directory allows multiple bytecode cache files to be
+co-located.  This PEP implements a similar mechanism for shared object files by
+giving them a common directory and distinct names for each version.
+
+The common directory is "pyshared" and the file names are made distinct by
+identifying the Python implementation (such as CPython, PyPy, Jython, etc.), the
+major and minor version numbers, and optional build flags (such as "d" for
+debug, "m" for pymalloc, "u" for wide-unicode).  For an arbitrary package "foo",
+you may see these files when the distribution package is installed::
+
+   /usr/share/pyshared/foo.cpython-32m.so
+   /usr/share/pyshared/foo.cpython-33md.so
+
+In Python itself, the tags are accessible from functions in the :mod:`sysconfig`
+module::
+
+   >>> import sysconfig
+   >>> sysconfig.get_config_var('SOABI')    # find the version tag
+   'cpython-32mu'
+   >>> sysconfig.get_config_var('SO')       # find the full filename extension
+   '.cpython-32mu.so'
+
+.. seealso::
+
+   :pep:`3149` - ABI Version Tagged .so Files
+      PEP written by Barry Warsaw.
+
+
+PEP 3333: Python Web Server Gateway Interface v1.0.1
+=====================================================
+
+This informational PEP clarifies how bytes/text issues are to be handled by the
+WGSI protocol.  The challenge is that string handling in Python 3 is most
+conveniently handled with the :class:`str` type even though the HTTP protocol
+is itself bytes oriented.
+
+The PEP differentiates so-called *native strings* that are used for
+request/response headers and metadata versus *byte strings* which are used for
+the bodies of requests and responses.
+
+The *native strings* are always of type :class:`str` but are restricted to code
+points between *U+0000* through *U+00FF* which are translatable to bytes using
+*Latin-1* encoding.  These strings are used for the keys and values in the
+environment dictionary and for response headers and statuses in the
+:func:`start_response` function.  They must follow :rfc:`2616` with respect to
+encoding. That is, they must either be *ISO-8859-1* characters or use
+:rfc:`2047` MIME encoding.
+
+For developers porting WSGI applications from Python 2, here are the salient
+points:
+
+* If the app already used strings for headers in Python 2, no change is needed.
+
+* If instead, the app encoded output headers or decoded input headers, then the
+  headers will need to be re-encoded to Latin-1.  For example, an output header
+  encoded in utf-8 was using ``h.encode('utf-8')`` now needs to convert from
+  bytes to native strings using ``h.encode('utf-8').decode('latin-1')``.
+
+* Values yielded by an application or sent using the :meth:`write` method
+  must be byte strings.  The :func:`start_response` function and environ
+  must use native strings.  The two cannot be mixed.
+
+For server implementers writing CGI-to-WSGI pathways or other CGI-style
+protocols, the users must to be able access the environment using native strings
+even though the underlying platform may have a different convention.  To bridge
+this gap, the :mod:`wsgiref` module has a new function,
+:func:`wsgiref.handlers.read_environ` for transcoding CGI variables from
+:attr:`os.environ` into native strings and returning a new dictionary.
+
+.. seealso::
+
+   :pep:`3333` - Python Web Server Gateway Interface v1.0.1
+      PEP written by Phillip Eby.
+
+
+Other Language Changes
+======================
+
+Some smaller changes made to the core Python language are:
+
+* String formatting for :func:`format` and :meth:`str.format` gained new
+  capabilities for the format character **#**.  Previously, for integers in
+  binary, octal, or hexadecimal, it caused the output to be prefixed with '0b',
+  '0o', or '0x' respectively.  Now it can also handle floats, complex, and
+  Decimal, causing the output to always have a decimal point even when no digits
+  follow it.
+
+  >>> format(20, '#o')
+  '0o24'
+  >>> format(12.34, '#5.0f')
+  '  12.'
+
+  (Suggested by Mark Dickinson and implemented by Eric Smith in :issue:`7094`.)
+
+* There is also a new :meth:`str.format_map` method that extends the
+  capabilities of the existing :meth:`str.format` method by accepting arbitrary
+  :term:`mapping` objects.  This new method makes it possible to use string
+  formatting with any of Python's many dictionary-like objects such as
+  :class:`~collections.defaultdict`, :class:`~shelve.Shelf`,
+  :class:`~configparser.ConfigParser`, or :mod:`dbm`.  It is also useful with
+  custom :class:`dict` subclasses that normalize keys before look-up or that
+  supply a :meth:`__missing__` method for unknown keys::
+
+    >>> import shelve
+    >>> d = shelve.open('tmp.shl')
+    >>> 'The {project_name} status is {status} as of {date}'.format_map(d)
+    'The testing project status is green as of February 15, 2011'
+
+    >>> class LowerCasedDict(dict):
+            def __getitem__(self, key):
+                return dict.__getitem__(self, key.lower())
+    >>> lcd = LowerCasedDict(part='widgets', quantity=10)
+    >>> 'There are {QUANTITY} {Part} in stock'.format_map(lcd)
+    'There are 10 widgets in stock'
+
+    >>> class PlaceholderDict(dict):
+            def __missing__(self, key):
+                return '<{}>'.format(key)
+    >>> 'Hello {name}, welcome to {location}'.format_map(PlaceholderDict())
+    'Hello <name>, welcome to <location>'
+
+ (Suggested by Raymond Hettinger and implemented by Eric Smith in
+ :issue:`6081`.)
+
+* The interpreter can now be started with a quiet option, ``-q``, to prevent
+  the copyright and version information from being displayed in the interactive
+  mode.  The option can be introspected using the :attr:`sys.flags` attribute::
+
+    $ python -q
+    >>> sys.flags
+    sys.flags(debug=0, division_warning=0, inspect=0, interactive=0,
+    optimize=0, dont_write_bytecode=0, no_user_site=0, no_site=0,
+    ignore_environment=0, verbose=0, bytes_warning=0, quiet=1)
+
+  (Contributed by Marcin Wojdyr in :issue:`1772833`).
+
+* The :func:`hasattr` function works by calling :func:`getattr` and detecting
+  whether an exception is raised.  This technique allows it to detect methods
+  created dynamically by :meth:`__getattr__` or :meth:`__getattribute__` which
+  would otherwise be absent from the class dictionary.  Formerly, *hasattr*
+  would catch any exception, possibly masking genuine errors.  Now, *hasattr*
+  has been tightened to only catch :exc:`AttributeError` and let other
+  exceptions pass through::
+
+    >>> class A:
+            @property
+            def f(self):
+                return 1 // 0
+
+    >>> a = A()
+    >>> hasattr(a, 'f')
+    Traceback (most recent call last):
+      ...
+    ZeroDivisionError: integer division or modulo by zero
+
+  (Discovered by Yury Selivanov and fixed by Benjamin Peterson; :issue:`9666`.)
+
+* The :func:`str` of a float or complex number is now the same as its
+  :func:`repr`. Previously, the :func:`str` form was shorter but that just
+  caused confusion and is no longer needed now that the shortest possible
+  :func:`repr` is displayed by default:
+
+   >>> import math
+   >>> repr(math.pi)
+   '3.141592653589793'
+   >>> str(math.pi)
+   '3.141592653589793'
+
+  (Proposed and implemented by Mark Dickinson; :issue:`9337`.)
+
+* :class:`memoryview` objects now have a :meth:`~memoryview.release()` method
+  and they also now support the context manager protocol.  This allows timely
+  release of any resources that were acquired when requesting a buffer from the
+  original object.
+
+  >>> with memoryview(b'abcdefgh') as v:
+          print(v.tolist())
+  [97, 98, 99, 100, 101, 102, 103, 104]
+
+  (Added by Antoine Pitrou; :issue:`9757`.)
+
+* Previously it was illegal to delete a name from the local namespace if it
+  occurs as a free variable in a nested block::
+
+       def outer(x):
+           def inner():
+              return x
+           inner()
+           del x
+
+  This is now allowed.  Remember that the target of an :keyword:`except` clause
+  is cleared, so this code which used to work with Python 2.6, raised a
+  :exc:`SyntaxError` with Python 3.1 and now works again::
+
+       def f():
+           def print_error():
+              print(e)
+           try:
+              something
+           except Exception as e:
+              print_error()
+              # implicit "del e" here
+
+  (See :issue:`4617`.)
+
+* The internal :c:type:`structsequence` tool now creates subclasses of tuple.
+  This means that C structures like those returned by :func:`os.stat`,
+  :func:`time.gmtime`, and :attr:`sys.version_info` now work like a
+  :term:`named tuple` and now work with functions and methods that
+  expect a tuple as an argument.  This is a big step forward in making the C
+  structures as flexible as their pure Python counterparts:
+
+  >>> isinstance(sys.version_info, tuple)
+  True
+  >>> 'Version %d.%d.%d %s(%d)' % sys.version_info
+  'Version 3.2.0 final(0)'
+
+  (Suggested by Arfrever Frehtes Taifersar Arahesis and implemented
+  by Benjamin Peterson in :issue:`8413`.)
+
+* Warnings are now easier to control using the :envvar:`PYTHONWARNINGS`
+  environment variable as an alternative to using ``-W`` at the command line::
+
+    $ export PYTHONWARNINGS='ignore::RuntimeWarning::,once::UnicodeWarning::'
+
+  (Suggested by Barry Warsaw and implemented by Philip Jenvey in :issue:`7301`.)
+
+* A new warning category, :exc:`ResourceWarning`, has been added.  It is
+  emitted when potential issues with resource consumption or cleanup
+  are detected.  It is silenced by default in normal release builds but
+  can be enabled through the means provided by the :mod:`warnings`
+  module, or on the command line.
+
+  A :exc:`ResourceWarning` is issued at interpreter shutdown if the
+  :data:`gc.garbage` list isn't empty, and if :attr:`gc.DEBUG_UNCOLLECTABLE` is
+  set, all uncollectable objects are printed.  This is meant to make the
+  programmer aware that their code contains object finalization issues.
+
+  A :exc:`ResourceWarning` is also issued when a :term:`file object` is destroyed
+  without having been explicitly closed.  While the deallocator for such
+  object ensures it closes the underlying operating system resource
+  (usually, a file descriptor), the delay in deallocating the object could
+  produce various issues, especially under Windows.  Here is an example
+  of enabling the warning from the command line::
+
+      $ python -q -Wdefault
+      >>> f = open("foo", "wb")
+      >>> del f
+      __main__:1: ResourceWarning: unclosed file <_io.BufferedWriter name='foo'>
+
+  (Added by Antoine Pitrou and Georg Brandl in :issue:`10093` and :issue:`477863`.)
+
+* :class:`range` objects now support *index* and *count* methods. This is part
+  of an effort to make more objects fully implement the
+  :class:`collections.Sequence` :term:`abstract base class`.  As a result, the
+  language will have a more uniform API.  In addition, :class:`range` objects
+  now support slicing and negative indices, even with values larger than
+  :attr:`sys.maxsize`.  This makes *range* more interoperable with lists::
+
+      >>> range(0, 100, 2).count(10)
+      1
+      >>> range(0, 100, 2).index(10)
+      5
+      >>> range(0, 100, 2)[5]
+      10
+      >>> range(0, 100, 2)[0:5]
+      range(0, 10, 2)
+
+  (Contributed by Daniel Stutzbach in :issue:`9213`, by Alexander Belopolsky
+  in :issue:`2690`, and by Nick Coghlan in :issue:`10889`.)
+
+* The :func:`callable` builtin function from Py2.x was resurrected.  It provides
+  a concise, readable alternative to using an :term:`abstract base class` in an
+  expression like ``isinstance(x, collections.Callable)``:
+
+  >>> callable(max)
+  True
+  >>> callable(20)
+  False
+
+  (See :issue:`10518`.)
+
+* Python's import mechanism can now load modules installed in directories with
+  non-ASCII characters in the path name.  This solved an aggravating problem
+  with home directories for users with non-ASCII characters in their usernames.
+
+ (Required extensive work by Victor Stinner in :issue:`9425`.)
+
+
+New, Improved, and Deprecated Modules
+=====================================
+
+Python's standard library has undergone significant maintenance efforts and
+quality improvements.
+
+The biggest news for Python 3.2 is that the :mod:`email` package, :mod:`mailbox`
+module, and :mod:`nntplib` modules now work correctly with the bytes/text model
+in Python 3.  For the first time, there is correct handling of messages with
+mixed encodings.
+
+Throughout the standard library, there has been more careful attention to
+encodings and text versus bytes issues.  In particular, interactions with the
+operating system are now better able to exchange non-ASCII data using the
+Windows MBCS encoding, locale-aware encodings, or UTF-8.
+
+Another significant win is the addition of substantially better support for
+*SSL* connections and security certificates.
+
+In addition, more classes now implement a :term:`context manager` to support
+convenient and reliable resource clean-up using a :keyword:`with` statement.
+
+email
+-----
+
+The usability of the :mod:`email` package in Python 3 has been mostly fixed by
+the extensive efforts of R. David Murray.  The problem was that emails are
+typically read and stored in the form of :class:`bytes` rather than :class:`str`
+text, and they may contain multiple encodings within a single email.  So, the
+email package had to be extended to parse and generate email messages in bytes
+format.
+
+* New functions :func:`~email.message_from_bytes` and
+  :func:`~email.message_from_binary_file`, and new classes
+  :class:`~email.parser.BytesFeedParser` and :class:`~email.parser.BytesParser`
+  allow binary message data to be parsed into model objects.
+
+* Given bytes input to the model, :meth:`~email.message.Message.get_payload`
+  will by default decode a message body that has a
+  :mailheader:`Content-Transfer-Encoding` of *8bit* using the charset
+  specified in the MIME headers and return the resulting string.
+
+* Given bytes input to the model, :class:`~email.generator.Generator` will
+  convert message bodies that have a :mailheader:`Content-Transfer-Encoding` of
+  *8bit* to instead have a *7bit* :mailheader:`Content-Transfer-Encoding`.
+
+  Headers with unencoded non-ASCII bytes are deemed to be :rfc:`2047`\ -encoded
+  using the *unknown-8bit* character set.
+
+* A new class :class:`~email.generator.BytesGenerator` produces bytes as output,
+  preserving any unchanged non-ASCII data that was present in the input used to
+  build the model, including message bodies with a
+  :mailheader:`Content-Transfer-Encoding` of *8bit*.
+
+* The :mod:`smtplib` :class:`~smtplib.SMTP` class now accepts a byte string
+  for the *msg* argument to the :meth:`~smtplib.SMTP.sendmail` method,
+  and a new method, :meth:`~smtplib.SMTP.send_message` accepts a
+  :class:`~email.message.Message` object and can optionally obtain the
+  *from_addr* and *to_addrs* addresses directly from the object.
+
+(Proposed and implemented by R. David Murray, :issue:`4661` and :issue:`10321`.)
+
+elementtree
+-----------
+
+The :mod:`xml.etree.ElementTree` package and its :mod:`xml.etree.cElementTree`
+counterpart have been updated to version 1.3.
+
+Several new and useful functions and methods have been added:
+
+* :func:`xml.etree.ElementTree.fromstringlist` which builds an XML document
+  from a sequence of fragments
+* :func:`xml.etree.ElementTree.register_namespace` for registering a global
+  namespace prefix
+* :func:`xml.etree.ElementTree.tostringlist` for string representation
+  including all sublists
+* :meth:`xml.etree.ElementTree.Element.extend` for appending a sequence of zero
+  or more elements
+* :meth:`xml.etree.ElementTree.Element.iterfind` searches an element and
+  subelements
+* :meth:`xml.etree.ElementTree.Element.itertext` creates a text iterator over
+  an element and its subelements
+* :meth:`xml.etree.ElementTree.TreeBuilder.end` closes the current element
+* :meth:`xml.etree.ElementTree.TreeBuilder.doctype` handles a doctype
+  declaration
+
+Two methods have been deprecated:
+
+* :meth:`xml.etree.ElementTree.getchildren` use ``list(elem)`` instead.
+* :meth:`xml.etree.ElementTree.getiterator` use ``Element.iter`` instead.
+
+For details of the update, see `Introducing ElementTree
+<http://effbot.org/zone/elementtree-13-intro.htm>`_ on Fredrik Lundh's website.
+
+(Contributed by Florent Xicluna and Fredrik Lundh, :issue:`6472`.)
+
+functools
+---------
+
+* The :mod:`functools` module includes a new decorator for caching function
+  calls.  :func:`functools.lru_cache` can save repeated queries to an external
+  resource whenever the results are expected to be the same.
+
+  For example, adding a caching decorator to a database query function can save
+  database accesses for popular searches:
+
+  >>> import functools
+  >>> @functools.lru_cache(maxsize=300)
+  >>> def get_phone_number(name):
+          c = conn.cursor()
+          c.execute('SELECT phonenumber FROM phonelist WHERE name=?', (name,))
+          return c.fetchone()[0]
+
+  >>> for name in user_requests:
+          get_phone_number(name)        # cached lookup
+
+  To help with choosing an effective cache size, the wrapped function is
+  instrumented for tracking cache statistics:
+
+  >>> get_phone_number.cache_info()
+  CacheInfo(hits=4805, misses=980, maxsize=300, currsize=300)
+
+  If the phonelist table gets updated, the outdated contents of the cache can be
+  cleared with:
+
+  >>> get_phone_number.cache_clear()
+
+  (Contributed by Raymond Hettinger and incorporating design ideas from Jim
+  Baker, Miki Tebeka, and Nick Coghlan; see `recipe 498245
+  <http://code.activestate.com/recipes/498245>`_\, `recipe 577479
+  <http://code.activestate.com/recipes/577479>`_\, :issue:`10586`, and
+  :issue:`10593`.)
+
+* The :func:`functools.wraps` decorator now adds a :attr:`__wrapped__` attribute
+  pointing to the original callable function.  This allows wrapped functions to
+  be introspected.  It also copies :attr:`__annotations__` if defined.  And now
+  it also gracefully skips over missing attributes such as :attr:`__doc__` which
+  might not be defined for the wrapped callable.
+
+  In the above example, the cache can be removed by recovering the original
+  function:
+
+  >>> get_phone_number = get_phone_number.__wrapped__    # uncached function
+
+  (By Nick Coghlan and Terrence Cole; :issue:`9567`, :issue:`3445`, and
+  :issue:`8814`.)
+
+* To help write classes with rich comparison methods, a new decorator
+  :func:`functools.total_ordering` will use a existing equality and inequality
+  methods to fill in the remaining methods.
+
+  For example, supplying *__eq__* and *__lt__* will enable
+  :func:`~functools.total_ordering` to fill-in *__le__*, *__gt__* and *__ge__*::
+
+    @total_ordering
+    class Student:
+        def __eq__(self, other):
+            return ((self.lastname.lower(), self.firstname.lower()) ==
+                    (other.lastname.lower(), other.firstname.lower()))
+        def __lt__(self, other):
+            return ((self.lastname.lower(), self.firstname.lower()) <
+                    (other.lastname.lower(), other.firstname.lower()))
+
+  With the *total_ordering* decorator, the remaining comparison methods
+  are filled in automatically.
+
+  (Contributed by Raymond Hettinger.)
+
+* To aid in porting programs from Python 2, the :func:`functools.cmp_to_key`
+  function converts an old-style comparison function to
+  modern :term:`key function`:
+
+  >>> # locale-aware sort order
+  >>> sorted(iterable, key=cmp_to_key(locale.strcoll))
+
+  For sorting examples and a brief sorting tutorial, see the `Sorting HowTo
+  <http://wiki.python.org/moin/HowTo/Sorting/>`_ tutorial.

+
+itertools
+---------
+
+* The :mod:`itertools` module has a new :func:`~itertools.accumulate` function
+  modeled on APL's *scan* operator and Numpy's *accumulate* function:
+
+  >>> from itertools import accumulate
+  >>> list(accumulate([8, 2, 50]))
+  [8, 10, 60]
+
+  >>> prob_dist = [0.1, 0.4, 0.2, 0.3]
+  >>> list(accumulate(prob_dist))      # cumulative probability distribution
+  [0.1, 0.5, 0.7, 1.0]
+
+  For an example using :func:`~itertools.accumulate`, see the :ref:`examples for
+  the random module <random-examples>`.
+
+  (Contributed by Raymond Hettinger and incorporating design suggestions
+  from Mark Dickinson.)
+
+collections
+-----------
+
+* The :class:`collections.Counter` class now has two forms of in-place
+  subtraction, the existing *-=* operator for `saturating subtraction
+  <http://en.wikipedia.org/wiki/Saturation_arithmetic>`_ and the new
+  :meth:`~collections.Counter.subtract` method for regular subtraction.  The
+  former is suitable for `multisets <http://en.wikipedia.org/wiki/Multiset>`_
+  which only have positive counts, and the latter is more suitable for use cases
+  that allow negative counts:
+
+  >>> tally = Counter(dogs=5, cat=3)
+  >>> tally -= Counter(dogs=2, cats=8)    # saturating subtraction
+  >>> tally
+  Counter({'dogs': 3})
+
+  >>> tally = Counter(dogs=5, cats=3)
+  >>> tally.subtract(dogs=2, cats=8)      # regular subtraction
+  >>> tally
+  Counter({'dogs': 3, 'cats': -5})

+
+* The :class:`collections.OrderedDict` class has a new method
+  :meth:`~collections.OrderedDict.move_to_end` which takes an existing key and
+  moves it to either the first or last position in the ordered sequence.
+
+  The default is to move an item to the last position.  This is equivalent of
+  renewing an entry with ``od[k] = od.pop(k)``.
+
+  A fast move-to-end operation is useful for resequencing entries.  For example,
+  an ordered dictionary can be used to track order of access by aging entries
+  from the oldest to the most recently accessed.
+
+  >>> d = OrderedDict.fromkeys(['a', 'b', 'X', 'd', 'e'])
+  >>> list(d)
+  ['a', 'b', 'X', 'd', 'e']
+  >>> d.move_to_end('X')
+  >>> list(d)
+  ['a', 'b', 'd', 'e', 'X']
+
+  (Contributed by Raymond Hettinger.)
+
+* The :class:`collections.deque` class grew two new methods
+  :meth:`~collections.deque.count` and :meth:`~collections.deque.reverse` that
+  make them more substitutable for :class:`list` objects:
+
+  >>> d = deque('simsalabim')
+  >>> d.count('s')
+  2
+  >>> d.reverse()
+  >>> d
+  deque(['m', 'i', 'b', 'a', 'l', 'a', 's', 'm', 'i', 's'])

+
+threading
+---------
+
+The :mod:`threading` module has a new :class:`~threading.Barrier`
+synchronization class for making multiple threads wait until all of them have
+reached a common barrier point.  Barriers are useful for making sure that a task
+with multiple preconditions does not run until all of the predecessor tasks are
+complete.
+
+Barriers can work with an arbitrary number of threads.  This is a generalization
+of a `Rendezvous <http://en.wikipedia.org/wiki/Synchronous_rendezvous>`_ which
+is defined for only two threads.
+
+Implemented as a two-phase cyclic barrier, :class:`~threading.Barrier` objects
+are suitable for use in loops.  The separate *filling* and *draining* phases
+assure that all threads get released (drained) before any one of them can loop
+back and re-enter the barrier.  The barrier fully resets after each cycle.
+
+Example of using barriers::
+
+    from threading import Barrier, Thread
+
+    def get_votes(site):
+        ballots = conduct_election(site)
+        all_polls_closed.wait()        # do not count until all polls are closed
+        totals = summarize(ballots)
+        publish(site, totals)
+
+    all_polls_closed = Barrier(len(sites))
+    for site in sites:
+        Thread(target=get_votes, args=(site,)).start()
+
+In this example, the barrier enforces a rule that votes cannot be counted at any
+polling site until all polls are closed.  Notice how a solution with a barrier
+is similar to one with :meth:`threading.Thread.join`, but the threads stay alive
+and continue to do work (summarizing ballots) after the barrier point is
+crossed.
+
+If any of the predecessor tasks can hang or be delayed, a barrier can be created
+with an optional *timeout* parameter.  Then if the timeout period elapses before
+all the predecessor tasks reach the barrier point, all waiting threads are
+released and a :exc:`~threading.BrokenBarrierError` exception is raised::
+
+    def get_votes(site):
+        ballots = conduct_election(site)
+        try:
+            all_polls_closed.wait(timeout = midnight - time.now())
+        except BrokenBarrierError:
+            lockbox = seal_ballots(ballots)
+            queue.put(lockbox)
+        else:
+            totals = summarize(ballots)
+            publish(site, totals)
+
+In this example, the barrier enforces a more robust rule.  If some election
+sites do not finish before midnight, the barrier times-out and the ballots are
+sealed and deposited in a queue for later handling.
+
+See `Barrier Synchronization Patterns
+<http://parlab.eecs.berkeley.edu/wiki/_media/patterns/paraplop_g1_3.pdf>`_ for
+more examples of how barriers can be used in parallel computing.  Also, there is
+a simple but thorough explanation of barriers in `The Little Book of Semaphores
+<http://greenteapress.com/semaphores/downey08semaphores.pdf>`_, *section 3.6*.

+
+datetime and time
+-----------------
+
+* The :mod:`datetime` module has a new type :class:`~datetime.timezone` that
+  implements the :class:`~datetime.tzinfo` interface by returning a fixed UTC
+  offset and timezone name. This makes it easier to create timezone-aware
+  datetime objects::
+
+    >>> from datetime import datetime, timezone
+
+    >>> datetime.now(timezone.utc)
+    datetime.datetime(2010, 12, 8, 21, 4, 2, 923754, tzinfo=datetime.timezone.utc)
+
+    >>> datetime.strptime("01/01/2000 12:00 +0000", "%m/%d/%Y %H:%M %z")
+    datetime.datetime(2000, 1, 1, 12, 0, tzinfo=datetime.timezone.utc)
+
+* Also, :class:`~datetime.timedelta` objects can now be multiplied by
+  :class:`float` and divided by :class:`float` and :class:`int` objects.
+  And :class:`~datetime.timedelta` objects can now divide one another.
+
+* The :meth:`datetime.date.strftime` method is no longer restricted to years
+  after 1900.  The new supported year range is from 1000 to 9999 inclusive.
+
+* Whenever a two-digit year is used in a time tuple, the interpretation has been
+  governed by :attr:`time.accept2dyear`.  The default is *True* which means that
+  for a two-digit year, the century is guessed according to the POSIX rules
+  governing the ``%y`` strptime format.
+
+  Starting with Py3.2, use of the century guessing heuristic will emit a
+  :exc:`DeprecationWarning`.  Instead, it is recommended that
+  :attr:`time.accept2dyear` be set to *False* so that large date ranges
+  can be used without guesswork::
+
+    >>> import time, warnings
+    >>> warnings.resetwarnings()      # remove the default warning filters
+
+    >>> time.accept2dyear = True      # guess whether 11 means 11 or 2011
+    >>> time.asctime((11, 1, 1, 12, 34, 56, 4, 1, 0))
+    Warning (from warnings module):
+      ...
+    DeprecationWarning: Century info guessed for a 2-digit year.
+    'Fri Jan  1 12:34:56 2011'
+
+    >>> time.accept2dyear = False     # use the full range of allowable dates
+    >>> time.asctime((11, 1, 1, 12, 34, 56, 4, 1, 0))
+    'Fri Jan  1 12:34:56 11'
+
+  Several functions now have significantly expanded date ranges.  When
+  :attr:`time.accept2dyear` is false, the :func:`time.asctime` function will
+  accept any year that fits in a C int, while the :func:`time.mktime` and
+  :func:`time.strftime` functions will accept the full range supported by the
+  corresponding operating system functions.

+
+math
+----
+
+The :mod:`math` module has been updated with six new functions inspired by the
+C99 standard.
+
+The :func:`~math.isfinite` function provides a reliable and fast way to detect
+special values.  It returns *True* for regular numbers and *False* for *Nan* or
+*Infinity*:
+
+>>> [isfinite(x) for x in (123, 4.56, float('Nan'), float('Inf'))]
+[True, True, False, False]
+
+The :func:`~math.expm1` function computes ``e**x-1`` for small values of *x*
+without incurring the loss of precision that usually accompanies the subtraction
+of nearly equal quantities:
+
+>>> expm1(0.013671875)   # more accurate way to compute e**x-1 for a small x
+0.013765762467652909
+
+The :func:`~math.erf` function computes a probability integral or `Gaussian
+error function <http://en.wikipedia.org/wiki/Error_function>`_.  The
+complementary error function, :func:`~math.erfc`, is ``1 - erf(x)``:
+
+>>> erf(1.0/sqrt(2.0))   # portion of normal distribution within 1 standard deviation
+0.682689492137086
+>>> erfc(1.0/sqrt(2.0))  # portion of normal distribution outside 1 standard deviation
+0.31731050786291404
+>>> erf(1.0/sqrt(2.0)) + erfc(1.0/sqrt(2.0))
+1.0
+
+The :func:`~math.gamma` function is a continuous extension of the factorial
+function.  See http://en.wikipedia.org/wiki/Gamma_function for details.  Because
+the function is related to factorials, it grows large even for small values of
+*x*, so there is also a :func:`~math.lgamma` function for computing the natural
+logarithm of the gamma function:
+
+>>> gamma(7.0)           # six factorial
+720.0
+>>> lgamma(801.0)        # log(800 factorial)

+abc
+---
+
+The :mod:`abc` module now supports :func:`~abc.abstractclassmethod` and
+:func:`~abc.abstractstaticmethod`.
+
+These tools make it possible to define an :term:`abstract base class` that
+requires a particular :func:`classmethod` or :func:`staticmethod` to be
+implemented::
+
+    class Temperature(metaclass=abc.ABCMeta):
+        @abc.abstractclassmethod
+        def from_fahrenheit(cls, t):
+            ...

+(Patch submitted by Daniel Urban; :issue:`5867`.)
+
+io
+--
+
+The :class:`io.BytesIO` has a new method, :meth:`~io.BytesIO.getbuffer`, which
+provides functionality similar to :func:`memoryview`.  It creates an editable
+view of the data without making a copy.  The buffer's random access and support
+for slice notation are well-suited to in-place editing::
+
+    >>> REC_LEN, LOC_START, LOC_LEN = 34, 7, 11
+
+    >>> def change_location(buffer, record_number, location):
+            start = record_number * REC_LEN + LOC_START
+            buffer[start: start+LOC_LEN] = location
+
+    >>> import io
+
+    >>> byte_stream = io.BytesIO(
+        b'G3805  storeroom  Main chassis    '
+        b'X7899  shipping   Reserve cog     '
+        b'L6988  receiving  Primary sprocket'
+    )
+    >>> buffer = byte_stream.getbuffer()
+    >>> change_location(buffer, 1, b'warehouse  ')
+    >>> change_location(buffer, 0, b'showroom   ')
+    >>> print(byte_stream.getvalue())

+
+reprlib
+-------
+
+When writing a :meth:`__repr__` method for a custom container, it is easy to
+forget to handle the case where a member refers back to the container itself.
+Python's builtin objects such as :class:`list` and :class:`set` handle
+self-reference by displaying "..." in the recursive part of the representation
+string.
+
+To help write such :meth:`__repr__` methods, the :mod:`reprlib` module has a new
+decorator, :func:`~reprlib.recursive_repr`, for detecting recursive calls to
+:meth:`__repr__` and substituting a placeholder string instead::
+
+        >>> class MyList(list):
+                @recursive_repr()
+                def __repr__(self):
+                    return '<' + '|'.join(map(repr, self)) + '>'
+
+        >>> m = MyList('abc')
+        >>> m.append(m)
+        >>> m.append('x')
+        >>> print(m)
+        <'a'|'b'|'c'|...|'x'>
+
+(Contributed by Raymond Hettinger in :issue:`9826` and :issue:`9840`.)
+
+logging
+-------
+
+In addition to dictionary-based configuration described above, the
+:mod:`logging` package has many other improvements.
+
+The logging documentation has been augmented by a :ref:`basic tutorial
+<logging-basic-tutorial>`\, an :ref:`advanced tutorial
+<logging-advanced-tutorial>`\, and a :ref:`cookbook <logging-cookbook>` of
+logging recipes.  These documents are the fastest way to learn about logging.
+
+The :func:`logging.basicConfig` set-up function gained a *style* argument to
+support three different types of string formatting.  It defaults to "%" for
+traditional %-formatting, can be set to "{" for the new :meth:`str.format` style, or
+can be set to "$" for the shell-style formatting provided by
+:class:`string.Template`.  The following three configurations are equivalent::
+
+    >>> from logging import basicConfig
+    >>> basicConfig(style='%', format="%(name)s -> %(levelname)s: %(message)s")
+    >>> basicConfig(style='{', format="{name} -> {levelname} {message}")
+    >>> basicConfig(style='$', format="$name -> $levelname: $message")
+
+If no configuration is set-up before a logging event occurs, there is now a
+default configuration using a :class:`~logging.StreamHandler` directed to
+:attr:`sys.stderr` for events of ``WARNING`` level or higher.  Formerly, an
+event occurring before a configuration was set-up would either raise an
+exception or silently drop the event depending on the value of
+:attr:`logging.raiseExceptions`.  The new default handler is stored in
+:attr:`logging.lastResort`.
+
+The use of filters has been simplified.  Instead of creating a
+:class:`~logging.Filter` object, the predicate can be any Python callable that
+returns *True* or *False*.
+
+There were a number of other improvements that add flexibility and simplify
+configuration.  See the module documentation for a full listing of changes in
+Python 3.2.
+
+csv
+---
+
+The :mod:`csv` module now supports a new dialect, :class:`~csv.unix_dialect`,
+which applies quoting for all fields and a traditional Unix style with ``'\n'`` as
+the line terminator.  The registered dialect name is ``unix``.
+
+The :class:`csv.DictWriter` has a new method,
+:meth:`~csv.DictWriter.writeheader` for writing-out an initial row to document
+the field names::
+
+    >>> import csv, sys
+    >>> w = csv.DictWriter(sys.stdout, ['name', 'dept'], dialect='unix')
+    >>> w.writeheader()
+    "name","dept"
+    >>> w.writerows([
+            {'name': 'tom', 'dept': 'accounting'},
+            {'name': 'susan', 'dept': 'Salesl'}])
+    "tom","accounting"
+    "susan","sales"
+
+(New dialect suggested by Jay Talbot in :issue:`5975`, and the new method
+suggested by Ed Abraham in :issue:`1537721`.)
+
+contextlib
+----------
+
+There is a new and slightly mind-blowing tool
+:class:`~contextlib.ContextDecorator` that is helpful for creating a
+:term:`context manager` that does double duty as a function decorator.
+
+As a convenience, this new functionality is used by
+:func:`~contextlib.contextmanager` so that no extra effort is needed to support
+both roles.
+
+The basic idea is that both context managers and function decorators can be used
+for pre-action and post-action wrappers.  Context managers wrap a group of
+statements using a :keyword:`with` statement, and function decorators wrap a
+group of statements enclosed in a function.  So, occasionally there is a need to
+write a pre-action or post-action wrapper that can be used in either role.
+
+For example, it is sometimes useful to wrap functions or groups of statements
+with a logger that can track the time of entry and time of exit.  Rather than
+writing both a function decorator and a context manager for the task, the
+:func:`~contextlib.contextmanager` provides both capabilities in a single
+definition::
+
+    from contextlib import contextmanager
+    import logging
+
+    logging.basicConfig(level=logging.INFO)
+
+    @contextmanager
+    def track_entry_and_exit(name):
+        logging.info('Entering: {}'.format(name))
+        yield
+        logging.info('Exiting: {}'.format(name))
+
+Formerly, this would have only been usable as a context manager::
+
+    with track_entry_and_exit('widget loader'):
+        print('Some time consuming activity goes here')
+        load_widget()
+
+Now, it can be used as a decorator as well::
+
+    @track_entry_and_exit('widget loader')
+    def activity():
+        print('Some time consuming activity goes here')
+        load_widget()
+
+Trying to fulfill two roles at once places some limitations on the technique.
+Context managers normally have the flexibility to return an argument usable by
+a :keyword:`with` statement, but there is no parallel for function decorators.
+
+In the above example, there is not a clean way for the *track_entry_and_exit*
+context manager to return a logging instance for use in the body of enclosed
+statements.

+
+decimal and fractions
+---------------------
+
+Mark Dickinson crafted an elegant and efficient scheme for assuring that
+different numeric datatypes will have the same hash value whenever their actual
+values are equal (:issue:`8188`)::
+
+   assert hash(Fraction(3, 2)) == hash(1.5) == \
+          hash(Decimal("1.5")) == hash(complex(1.5, 0))
+
+Some of the hashing details are exposed through a new attribute,
+:attr:`sys.hash_info`, which describes the bit width of the hash value, the
+prime modulus, the hash values for *infinity* and *nan*, and the multiplier
+used for the imaginary part of a number:
+
+>>> sys.hash_info
+sys.hash_info(width=64, modulus=2305843009213693951, inf=314159, nan=0, imag=1000003)
+
+An early decision to limit the inter-operability of various numeric types has
+been relaxed.  It is still unsupported (and ill-advised) to have implicit
+mixing in arithmetic expressions such as ``Decimal('1.1') + float('1.1')``
+because the latter loses information in the process of constructing the binary
+float.  However, since existing floating point value can be converted losslessly
+to either a decimal or rational representation, it makes sense to add them to
+the constructor and to support mixed-type comparisons.
+
+* The :class:`decimal.Decimal` constructor now accepts :class:`float` objects
+  directly so there in no longer a need to use the :meth:`~decimal.Decimal.from_float`
+  method (:issue:`8257`).
+
+* Mixed type comparisons are now fully supported so that
+  :class:`~decimal.Decimal` objects can be directly compared with :class:`float`
+  and :class:`fractions.Fraction` (:issue:`2531` and :issue:`8188`).
+
+Similar changes were made to :class:`fractions.Fraction` so that the
+:meth:`~fractions.Fraction.from_float()` and :meth:`~fractions.Fraction.from_decimal`
+methods are no longer needed (:issue:`8294`):
+
+>>> Decimal(1.1)
+Decimal('1.100000000000000088817841970012523233890533447265625')
+>>> Fraction(1.1)
+Fraction(2476979795053773, 2251799813685248)
+
+Another useful change for the :mod:`decimal` module is that the
+:attr:`Context.clamp` attribute is now public.  This is useful in creating
+contexts that correspond to the decimal interchange formats specified in IEEE
+754 (see :issue:`8540`).

+
+ftp
+---
+
+The :class:`ftplib.FTP` class now supports the context manager protocol to
+unconditionally consume :exc:`socket.error` exceptions and to close the FTP
+connection when done::
+
+ >>> from ftplib import FTP
+ >>> with FTP("ftp1.at.proftpd.org") as ftp:
+         ftp.login()
+         ftp.dir()
+
+ '230 Anonymous login ok, restrictions apply.'

+
+Other file-like objects such as :class:`mmap.mmap` and :func:`fileinput.input`
+also grew auto-closing context managers::

+The :class:`~tarfile.TarFile` class can now be used as a context manager.  In
+addition, its :meth:`~tarfile.TarFile.add` method has a new option, *filter*,
+that controls which files are added to the archive and allows the file metadata
+to be edited.
+
+The new *filter* option replaces the older, less flexible *exclude* parameter
+which is now deprecated.  If specified, the optional *filter* parameter needs to
+be a :term:`keyword argument`.  The user-supplied filter function accepts a
+:class:`~tarfile.TarInfo` object and returns an updated
+:class:`~tarfile.TarInfo` object, or if it wants the file to be excluded, the
+function can return *None*::
+
+    >>> import tarfile, glob
+
+    >>> def myfilter(tarinfo):
+           if tarinfo.isfile():             # only save real files
+                tarinfo.uname = 'monty'     # redact the user name
+                return tarinfo
+
+    >>> with tarfile.open(name='myarchive.tar.gz', mode='w:gz') as tf:
+            for filename in glob.glob('*.txt'):
+                tf.add(filename, filter=myfilter)
+            tf.list()

+
+hashlib
+-------
+
+The :mod:`hashlib` module has two new constant attributes listing the hashing
+algorithms guaranteed to be present in all implementations and those available
+on the current implementation::
+
+    >>> import hashlib
+
+    >>> hashlib.algorithms_guaranteed
+    {'sha1', 'sha224', 'sha384', 'sha256', 'sha512', 'md5'}
+
+    >>> hashlib.algorithms_available
+    {'md2', 'SHA256', 'SHA512', 'dsaWithSHA', 'mdc2', 'SHA224', 'MD4', 'sha256',
+    'sha512', 'ripemd160', 'SHA1', 'MDC2', 'SHA', 'SHA384', 'MD2',
+    'ecdsa-with-SHA1','md4', 'md5', 'sha1', 'DSA-SHA', 'sha224',
+    'dsaEncryption', 'DSA', 'RIPEMD160', 'sha', 'MD5', 'sha384'}
+
+(Suggested by Carl Chenet in :issue:`7418`.)
+
+ast
+---
+
+The :mod:`ast` module has a wonderful a general-purpose tool for safely
+evaluating expression strings using the Python literal
+syntax.  The :func:`ast.literal_eval` function serves as a secure alternative to
+the builtin :func:`eval` function which is easily abused.  Python 3.2 adds
+:class:`bytes` and :class:`set` literals to the list of supported types:
+strings, bytes, numbers, tuples, lists, dicts, sets, booleans, and None.
+
+::
+
+    >>> from ast import literal_eval
+
+    >>> request = "{'req': 3, 'func': 'pow', 'args': (2, 0.5)}"
+    >>> literal_eval(request)
+    {'args': (2, 0.5), 'req': 3, 'func': 'pow'}
+
+    >>> request = "os.system('do something harmful')"
+    >>> literal_eval(request)
+    Traceback (most recent call last):
+      ...
+    ValueError: malformed node or string: <_ast.Call object at 0x101739a10>
+
+(Implemented by Benjamin Peterson and Georg Brandl.)
+
+os
+--
+
+Different operating systems use various encodings for filenames and environment
+variables.  The :mod:`os` module provides two new functions,
+:func:`~os.fsencode` and :func:`~os.fsdecode`, for encoding and decoding
+filenames:
+
+>>> filename = 'Sehenswürdigkeiten'
+>>> os.fsencode(filename)
+b'Sehensw\xc3\xbcrdigkeiten'
+
+Some operating systems allow direct access to the unencoded bytes in the
+environment.  If so, the :attr:`os.supports_bytes_environ` constant will be
+true.
+
+For direct access to unencoded environment variables (if available),
+use the new :func:`os.getenvb` function or use :data:`os.environb`
+which is a bytes version of :data:`os.environ`.

+
+shutil
+------
+
+The :func:`shutil.copytree` function has two new options:
+
+* *ignore_dangling_symlinks*: when ``symlinks=False`` so that the function
+  copies a file pointed to by a symlink, not the symlink itself. This option
+  will silence the error raised if the file doesn't exist.
+
+* *copy_function*: is a callable that will be used to copy files.
+  :func:`shutil.copy2` is used by default.
+
+(Contributed by Tarek Ziadé.)
+
+In addition, the :mod:`shutil` module now supports :ref:`archiving operations
+<archiving-operations>` for zipfiles, uncompressed tarfiles, gzipped tarfiles,
+and bzipped tarfiles.  And there are functions for registering additional
+archiving file formats (such as xz compressed tarfiles or custom formats).
+
+The principal functions are :func:`~shutil.make_archive` and
+:func:`~shutil.unpack_archive`.  By default, both operate on the current
+directory (which can be set by :func:`os.chdir`) and on any sub-directories.
+The archive filename needs to be specified with a full pathname.  The archiving
+step is non-destructive (the original files are left unchanged).
+
+::
+
+    >>> import shutil, pprint
+
+    >>> os.chdir('mydata')                               # change to the source directory
+    >>> f = shutil.make_archive('/var/backup/mydata',
+                                'zip')                   # archive the current directory
+    >>> f                                                # show the name of archive
+    '/var/backup/mydata.zip'
+    >>> os.chdir('tmp')                                  # change to an unpacking
+    >>> shutil.unpack_archive('/var/backup/mydata.zip')  # recover the data
+
+    >>> pprint.pprint(shutil.get_archive_formats())      # display known formats
+    [('bztar', "bzip2'ed tar-file"),
+     ('gztar', "gzip'ed tar-file"),
+     ('tar', 'uncompressed tar file'),
+     ('zip', 'ZIP file')]
+
+    >>> shutil.register_archive_format(                  # register a new archive format
+            name = 'xz',
+            function = xz.compress,                      # callable archiving function
+            extra_args = [('level', 8)],                 # arguments to the function
+            description = 'xz compression'

+
+sqlite3
+-------
+
+The :mod:`sqlite3` module was updated to pysqlite version 2.6.0.  It has two new capabilities.
+
+* The :attr:`sqlite3.Connection.in_transit` attribute is true if there is an
+  active transaction for uncommitted changes.
+
+* The :meth:`sqlite3.Connection.enable_load_extension` and
+  :meth:`sqlite3.Connection.load_extension` methods allows you to load SQLite
+  extensions from ".so" files.  One well-known extension is the fulltext-search
+  extension distributed with SQLite.
+
+(Contributed by R. David Murray and Shashwat Anand; :issue:`8845`.)
+
+html
+----
+
+A new :mod:`html` module was introduced with only a single function,
+:func:`~html.escape`, which is used for escaping reserved characters from HTML
+markup:
+
+>>> import html
+>>> html.escape('x > 2 && x < 7')
+'x &gt; 2 &amp;&amp; x &lt; 7'
+
+socket
+------
+
+The :mod:`socket` module has two new improvements.
+
+* Socket objects now have a :meth:`~socket.socket.detach()` method which puts
+  the socket into closed state without actually closing the underlying file
+  descriptor.  The latter can then be reused for other purposes.
+  (Added by Antoine Pitrou; :issue:`8524`.)
+
+* :func:`socket.create_connection` now supports the context manager protocol
+  to unconditionally consume :exc:`socket.error` exceptions and to close the
+  socket when done.
+  (Contributed by Giampaolo Rodolà; :issue:`9794`.)
+
+ssl
+---
+
+The :mod:`ssl` module added a number of features to satisfy common requirements
+for secure (encrypted, authenticated) internet connections:
+
+* A new class, :class:`~ssl.SSLContext`, serves as a container for persistent
+  SSL data, such as protocol settings, certificates, private keys, and various
+  other options. It includes a :meth:`~ssl.SSLContext.wrap_socket` for creating
+  an SSL socket from an SSL context.
+
+* A new function, :func:`ssl.match_hostname`, supports server identity
+  verification for higher-level protocols by implementing the rules of HTTPS
+  (from :rfc:`2818`) which are also suitable for other protocols.
+
+* The :func:`ssl.wrap_socket` constructor function now takes a *ciphers*
+  argument.  The *ciphers* string lists the allowed encryption algorithms using
+  the format described in the `OpenSSL documentation
+  <http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT>`__.
+
+* When linked against recent versions of OpenSSL, the :mod:`ssl` module now
+  supports the Server Name Indication extension to the TLS protocol, allowing
+  multiple "virtual hosts" using different certificates on a single IP port.
+  This extension is only supported in client mode, and is activated by passing
+  the *server_hostname* argument to :meth:`ssl.SSLContext.wrap_socket`.
+
+* Various options have been added to the :mod:`ssl` module, such as
+  :data:`~ssl.OP_NO_SSLv2` which disables the insecure and obsolete SSLv2
+  protocol.
+
+* The extension now loads all the OpenSSL ciphers and digest algorithms.  If
+  some SSL certificates cannot be verified, they are reported as an "unknown
+  algorithm" error.
+
+* The version of OpenSSL being used is now accessible using the module
+  attributes :data:`ssl.OPENSSL_VERSION` (a string),
+  :data:`ssl.OPENSSL_VERSION_INFO` (a 5-tuple), and
+  :data:`ssl.OPENSSL_VERSION_NUMBER` (an integer).

+:issue:`5639`, :issue:`4870`, :issue:`8484`, and :issue:`8321`.)
+
+nntp
+----
+
+The :mod:`nntplib` module has a revamped implementation with better bytes and
+text semantics as well as more practical APIs.  These improvements break
+compatibility with the nntplib version in Python 3.1, which was partly
+dysfunctional in itself.
+
+Support for secure connections through both implicit (using
+:class:`nntplib.NNTP_SSL`) and explicit (using :meth:`nntplib.NNTP.starttls`)
+TLS has also been added.
+
+(Contributed by Antoine Pitrou in :issue:`9360` and Andrew Vant in :issue:`1926`.)
+
+certificates
+------------
+
+:class:`http.client.HTTPSConnection`, :class:`urllib.request.HTTPSHandler`
+and :func:`urllib.request.urlopen` now take optional arguments to allow for
+server certificate checking against a set of Certificate Authorities,
+as recommended in public uses of HTTPS.
+
+(Added by Antoine Pitrou, :issue:`9003`.)
+
+imaplib
+-------
+
+Support for explicit TLS on standard IMAP4 connections has been added through
+the new :mod:`imaplib.IMAP4.starttls` method.
+
+(Contributed by Lorenzo M. Catucci and Antoine Pitrou, :issue:`4471`.)
+
+http.client
+-----------
+
+There were a number of small API improvements in the :mod:`http.client` module.
+The old-style HTTP 0.9 simple responses are no longer supported and the *strict*
+parameter is deprecated in all classes.
+
+The :class:`~http.client.HTTPConnection` and
+:class:`~http.client.HTTPSConnection` classes now have a *source_address*
+parameter for a (host, port) tuple indicating where the HTTP connection is made
+from.
+
+Support for certificate checking and HTTPS virtual hosts were added to
+:class:`~http.client.HTTPSConnection`.
+
+The :meth:`~http.client.HTTPConnection.request` method on connection objects
+allowed an optional *body* argument so that a :term:`file object` could be used
+to supply the content of the request.  Conveniently, the *body* argument now
+also accepts an :term:`iterable` object so long as it includes an explicit
+``Content-Length`` header.  This extended interface is much more flexible than
+before.
+
+To establish an HTTPS connection through a proxy server, there is a new
+:meth:`~http.client.HTTPConnection.set_tunnel` method that sets the host and
+port for HTTP Connect tunneling.
+
+To match the behavior of :mod:`http.server`, the HTTP client library now also
+encodes headers with ISO-8859-1 (Latin-1) encoding.  It was already doing that
+for incoming headers, so now the behavior is consistent for both incoming and
+outgoing traffic. (See work by Armin Ronacher in :issue:`10980`.)
+
+unittest
+--------
+
+The unittest module has a number of improvements supporting test discovery for
+packages, easier experimentation at the interactive prompt, new testcase
+methods, improved diagnostic messages for test failures, and better method
+names.
+
+* The command-line call ``python -m unittest`` can now accept file paths
+  instead of module names for running specific tests (:issue:`10620`).  The new
+  test discovery can find tests within packages, locating any test importable
+  from the top-level directory.  The top-level directory can be specified with
+  the `-t` option, a pattern for matching files with ``-p``, and a directory to
+  start discovery with ``-s``::
+
+    $ python -m unittest discover -s my_proj_dir -p _test.py
+
+  (Contributed by Michael Foord.)
+
+* Experimentation at the interactive prompt is now easier because the
+  :class:`unittest.case.TestCase` class can now be instantiated without
+  arguments:
+
+  >>> TestCase().assertEqual(pow(2, 3), 8)
+
+  (Contributed by Michael Foord.)
+
+* The :mod:`unittest` module has two new methods,
+  :meth:`~unittest.TestCase.assertWarns` and
+  :meth:`~unittest.TestCase.assertWarnsRegex` to verify that a given warning type
+  is triggered by the code under test::
+
+      with self.assertWarns(DeprecationWarning):
+          legacy_function('XYZ')
+
+  (Contributed by Antoine Pitrou, :issue:`9754`.)
+
+  Another new method, :meth:`~unittest.TestCase.assertCountEqual` is used to
+  compare two iterables to determine if their element counts are equal (whether
+  the same elements are present with the same number of occurrences regardless
+  of order)::
+
+     def test_anagram(self):
+         self.assertCountEqual('algorithm', 'logarithm')
+
+  (Contributed by Raymond Hettinger.)
+
+* A principal feature of the unittest module is an effort to produce meaningful
+  diagnostics when a test fails.  When possible, the failure is recorded along
+  with a diff of the output.  This is especially helpful for analyzing log files
+  of failed test runs. However, since diffs can sometime be voluminous, there is
+  a new :attr:`~unittest.TestCase.maxDiff` attribute that sets maximum length of
+  diffs displayed.
+
+* In addition, the method names in the module have undergone a number of clean-ups.
+
+  For example, :meth:`~unittest.TestCase.assertRegex` is the new name for
+  :meth:`~unittest.TestCase.assertRegexpMatches` which was misnamed because the
+  test uses :func:`re.search`, not :func:`re.match`.  Other methods using
+  regular expressions are now named using short form "Regex" in preference to
+  "Regexp" -- this matches the names used in other unittest implementations,
+  matches Python's old name for the :mod:`re` module, and it has unambiguous
+  camel-casing.
+
+  (Contributed by Raymond Hettinger and implemented by Ezio Melotti.)
+
+* To improve consistency, some long-standing method aliases are being
+  deprecated in favor of the preferred names:
+
+   ===============================   ==============================
+   Old Name                          Preferred Name
+   ===============================   ==============================
+   :meth:`assert_`                   :meth:`.assertTrue`
+   :meth:`assertEquals`              :meth:`.assertEqual`
+   :meth:`assertNotEquals`           :meth:`.assertNotEqual`
+   :meth:`assertAlmostEquals`        :meth:`.assertAlmostEqual`
+   :meth:`assertNotAlmostEquals`     :meth:`.assertNotAlmostEqual`
+   ===============================   ==============================
+
+  Likewise, the ``TestCase.fail*`` methods deprecated in Python 3.1 are expected
+  to be removed in Python 3.3.  Also see the :ref:`deprecated-aliases` section in
+  the :mod:`unittest` documentation.
+
+  (Contributed by Ezio Melotti; :issue:`9424`.)
+
+* The :meth:`~unittest.TestCase.assertDictContainsSubset` method was deprecated
+  because it was misimplemented with the arguments in the wrong order.  This
+  created hard-to-debug optical illusions where tests like
+  ``TestCase().assertDictContainsSubset({'a':1, 'b':2}, {'a':1})`` would fail.
+
+  (Contributed by Raymond Hettinger.)
+
+random
+------
+
+The integer methods in the :mod:`random` module now do a better job of producing
+uniform distributions.  Previously, they computed selections with
+``int(n*random())`` which had a slight bias whenever *n* was not a power of two.
+Now, multiple selections are made from a range up to the next power of two and a
+selection is kept only when it falls within the range ``0 <= x < n``.  The
+functions and methods affected are :func:`~random.randrange`,
+:func:`~random.randint`, :func:`~random.choice`, :func:`~random.shuffle` and
+:func:`~random.sample`.
+
+(Contributed by Raymond Hettinger; :issue:`9025`.)
+
+poplib
+------
+
+:class:`~poplib.POP3_SSL` class now accepts a *context* parameter, which is a
+:class:`ssl.SSLContext` object allowing bundling SSL configuration options,
+certificates and private keys into a single (potentially long-lived)
+structure.
+
+(Contributed by Giampaolo Rodolà; :issue:`8807`.)
+
+asyncore
+--------
+
+:class:`asyncore.dispatcher` now provides a
+:meth:`~asyncore.dispatcher.handle_accepted()` method
+returning a `(sock, addr)` pair which is called when a connection has actually
+been established with a new remote endpoint. This is supposed to be used as a
+replacement for old :meth:`~asyncore.dispatcher.handle_accept()` and avoids
+the user  to call :meth:`~asyncore.dispatcher.accept()` directly.
+
+(Contributed by Giampaolo Rodolà; :issue:`6706`.)
+
+tempfile
+--------
+
+The :mod:`tempfile` module has a new context manager,
+:class:`~tempfile.TemporaryDirectory` which provides easy deterministic
+cleanup of temporary directories::
+
+    with tempfile.TemporaryDirectory() as tmpdirname:
+        print('created temporary dir:', tmpdirname)
+
+(Contributed by Neil Schemenauer and Nick Coghlan; :issue:`5178`.)
+
+inspect
+-------
+
+* The :mod:`inspect` module has a new function
+  :func:`~inspect.getgeneratorstate` to easily identify the current state of a
+  generator-iterator::
+
+    >>> from inspect import getgeneratorstate
+    >>> def gen():
+            yield 'demo'
+    >>> g = gen()
+    >>> getgeneratorstate(g)
+    'GEN_CREATED'
+    >>> next(g)
+    'demo'
+    >>> getgeneratorstate(g)
+    'GEN_SUSPENDED'
+    >>> next(g, None)
+    >>> getgeneratorstate(g)
+    'GEN_CLOSED'
+
+  (Contributed by Rodolpho Eckhardt and Nick Coghlan, :issue:`10220`.)
+
+* To support lookups without the possibility of activating a dynamic attribute,
+  the :mod:`inspect` module has a new function, :func:`~inspect.getattr_static`.
+  Unlike :func:`hasattr`, this is a true read-only search, guaranteed not to
+  change state while it is searching::
+
+    >>> class A:
+            @property
+            def f(self):
+                print('Running')
+                return 10
+
+    >>> a = A()
+    >>> getattr(a, 'f')

+    10

+
+pydoc
+-----
+
+The :mod:`pydoc` module now provides a much-improved Web server interface, as
+well as a new command-line option ``-b`` to automatically open a browser window
+to display that server::
+
+    $ pydoc3.2 -b
+
+(Contributed by Ron Adam; :issue:`2001`.)
+
+dis
+---
+
+The :mod:`dis` module gained two new functions for inspecting code,
+:func:`~dis.code_info` and :func:`~dis.show_code`.  Both provide detailed code
+object information for the supplied function, method, source code string or code
+object.  The former returns a string and the latter prints it::
+
+    >>> import dis, random
+    >>> dis.show_code(random.choice)
+    Name:              choice
+    Filename:          /Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/random.py
+    Argument count:    2
+    Kw-only arguments: 0
+    Number of locals:  3
+    Stack size:        11
+    Flags:             OPTIMIZED, NEWLOCALS, NOFREE
+    Constants:
+       0: 'Choose a random element from a non-empty sequence.'
+       1: 'Cannot choose from an empty sequence'
+    Names:
+       0: _randbelow
+       1: len
+       2: ValueError
+       3: IndexError
+    Variable names:
+       0: self
+       1: seq
+       2: i
+
+In addition, the :func:`~dis.dis` function now accepts string arguments
+so that the common idiom ``dis(compile(s, '', 'eval'))`` can be shortened
+to ``dis(s)``::
+
+    >>> dis('3*x+1 if x%2==1 else x//2')
+      1           0 LOAD_NAME                0 (x)
+                  3 LOAD_CONST               0 (2)

+                  7 LOAD_CONST               1 (1)
+                 10 COMPARE_OP               2 (==)
+                 13 POP_JUMP_IF_FALSE       28
+                 16 LOAD_CONST               2 (3)
+                 19 LOAD_NAME                0 (x)

+                 35 RETURN_VALUE

+(Suggested by Ray Allen in :issue:`9523`.)
+
+ctypes
+------
+
+A new type, :class:`ctypes.c_ssize_t` represents the C :c:type:`ssize_t` datatype.
+
+site
+----
+
+The :mod:`site` module has three new functions useful for reporting on the
+details of a given Python installation.
+
+* :func:`~site.getsitepackages` lists all global site-packages directories.
+
+* :func:`~site.getuserbase` reports on the user's base directory where data can
+  be stored.
+
+* :func:`~site.getusersitepackages` reveals the user-specific site-packages
+  directory path.
+
+::
+
+    >>> import site
+    >>> site.getsitepackages()
+    ['/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/site-packages',
+     '/Library/Frameworks/Python.framework/Versions/3.2/lib/site-python',
+     '/Library/Python/3.2/site-packages']
+    >>> site.getuserbase()
+    '/Users/raymondhettinger/Library/Python/3.2'
+    >>> site.getusersitepackages()
+    '/Users/raymondhettinger/Library/Python/3.2/lib/python/site-packages'
+
+Conveniently, some of site's functionality is accessible directly from the
+command-line::
+
+    $ python -m site --user-base
+    /Users/raymondhettinger/.local
+    $ python -m site --user-site
+    /Users/raymondhettinger/.local/lib/python3.2/site-packages

+
+sysconfig
+---------
+
+The new :mod:`sysconfig` module makes it straightforward to discover
+installation paths and configuration variables that vary across platforms and
+installations.
+
+The module offers access simple access functions for platform and version
+information:
+
+* :func:`~sysconfig.get_platform` returning values like *linux-i586* or
+  *macosx-10.6-ppc*.
+* :func:`~sysconfig.get_python_version` returns a Python version string
+  such as "3.2".
+
+It also provides access to the paths and variables corresponding to one of
+seven named schemes used by :mod:`distutils`.  Those include *posix_prefix*,
+*posix_home*, *posix_user*, *nt*, *nt_user*, *os2*, *os2_home*:
+
+* :func:`~sysconfig.get_paths` makes a dictionary containing installation paths
+  for the current installation scheme.
+* :func:`~sysconfig.get_config_vars` returns a dictionary of platform specific
+  variables.
+
+There is also a convenient command-line interface::
+
+  C:\Python32>python -m sysconfig
+  Platform: "win32"
+  Python version: "3.2"
+  Current installation scheme: "nt"
+
+  Paths:
+          data = "C:\Python32"
+          include = "C:\Python32\Include"
+          platinclude = "C:\Python32\Include"
+          platlib = "C:\Python32\Lib\site-packages"
+          platstdlib = "C:\Python32\Lib"
+          purelib = "C:\Python32\Lib\site-packages"
+          scripts = "C:\Python32\Scripts"
+          stdlib = "C:\Python32\Lib"
+
+  Variables:
+          BINDIR = "C:\Python32"
+          BINLIBDEST = "C:\Python32\Lib"
+          EXE = ".exe"
+          INCLUDEPY = "C:\Python32\Include"
+          LIBDEST = "C:\Python32\Lib"
+          SO = ".pyd"
+          VERSION = "32"
+          abiflags = ""
+          base = "C:\Python32"
+          exec_prefix = "C:\Python32"
+          platbase = "C:\Python32"
+          prefix = "C:\Python32"
+          projectbase = "C:\Python32"
+          py_version = "3.2"
+          py_version_nodot = "32"
+          py_version_short = "3.2"
+          srcdir = "C:\Python32"
+          userbase = "C:\Documents and Settings\Raymond\Application Data\Python"
+
+(Moved out of Distutils by Tarek Ziadé.)
+
+pdb
+---
+
+The :mod:`pdb` debugger module gained a number of usability improvements:
+
+* :file:`pdb.py` now has a ``-c`` option that executes commands as given in a
+  :file:`.pdbrc` script file.
+* A :file:`.pdbrc` script file can contain ``continue`` and ``next`` commands
+  that continue debugging.
+* The :class:`Pdb` class constructor now accepts a *nosigint* argument.
+* New commands: ``l(list)``, ``ll(long list)`` and ``source`` for
+  listing source code.
+* New commands: ``display`` and ``undisplay`` for showing or hiding
+  the value of an expression if it has changed.
+* New command: ``interact`` for starting an interactive interpreter containing
+  the global and local  names found in the current scope.
+* Breakpoints can be cleared by breakpoint number.
+

+
+configparser
+------------
+
+The :mod:`configparser` module was modified to improve usability and
+predictability of the default parser and its supported INI syntax.  The old
+:class:`ConfigParser` class was removed in favor of :class:`SafeConfigParser`
+which has in turn been renamed to :class:`~configparser.ConfigParser`. Support
+for inline comments is now turned off by default and section or option
+duplicates are not allowed in a single configuration source.
+
+Config parsers gained a new API based on the mapping protocol::
+
+    >>> parser = ConfigParser()
+    >>> parser.read_string("""
+    [DEFAULT]
+    location = upper left
+    visible = yes
+    editable = no
+    color = blue
+
+    [main]
+    title = Main Menu
+    color = green
+
+    [options]
+    title = Options
+    """)
+    >>> parser['main']['color']
+    'green'
+    >>> parser['main']['editable']
+    'no'
+    >>> section = parser['options']
+    >>> section['title']
+    'Options'
+    >>> section['title'] = 'Options (editable: %(editable)s)'
+    >>> section['title']
+    'Options (editable: no)'
+
+The new API is implemented on top of the classical API, so custom parser
+subclasses should be able to use it without modifications.
+
+The INI file structure accepted by config parsers can now be customized. Users
+can specify alternative option/value delimiters and comment prefixes, change the
+name of the *DEFAULT* section or switch the interpolation syntax.
+
+There is support for pluggable interpolation including an additional interpolation
+handler :class:`~configparser.ExtendedInterpolation`::
+
+  >>> parser = ConfigParser(interpolation=ExtendedInterpolation())
+  >>> parser.read_dict({'buildout': {'directory': '/home/ambv/zope9'},
+                        'custom': {'prefix': '/usr/local'}})
+  >>> parser.read_string("""
+      [buildout]
+      parts =
+        zope9
+        instance
+      find-links =
+        ${buildout:directory}/downloads/dist
+
+      [zope9]
+      recipe = plone.recipe.zope9install
+      location = /opt/zope
+
+      [instance]
+      recipe = plone.recipe.zope9instance
+      zope9-location = ${zope9:location}
+      zope-conf = ${custom:prefix}/etc/zope.conf
+      """)
+  >>> parser['buildout']['find-links']
+  '\n/home/ambv/zope9/downloads/dist'
+  >>> parser['instance']['zope-conf']
+  '/usr/local/etc/zope.conf'
+  >>> instance = parser['instance']
+  >>> instance['zope-conf']
+  '/usr/local/etc/zope.conf'
+  >>> instance['zope9-location']
+  '/opt/zope'
+
+A number of smaller features were also introduced, like support for specifying
+encoding in read operations, specifying fallback values for get-functions, or
+reading directly from dictionaries and strings.

+.. XXX consider showing a difflib example
+
+urllib.parse
+------------
+
+A number of usability improvements were made for the :mod:`urllib.parse` module.
+
+The :func:`~urllib.parse.urlparse` function now supports `IPv6
+<http://en.wikipedia.org/wiki/IPv6>`_ addresses as described in :rfc:`2732`:
+
+    >>> import urllib.parse
+    >>> urllib.parse.urlparse('http://[dead:beef:cafe:5417:affe:8FA3:deaf:feed]/foo/')
+    ParseResult(scheme='http',
+                netloc='[dead:beef:cafe:5417:affe:8FA3:deaf:feed]',
+                path='/foo/',
+                params='',
+                query='',
+                fragment='')
+
+The :func:`~urllib.parse.urldefrag` function now returns a :term:`named tuple`::
+
+    >>> r = urllib.parse.urldefrag('http://python.org/about/#target')
+    >>> r
+    DefragResult(url='http://python.org/about/', fragment='target')
+    >>> r[0]
+    'http://python.org/about/'
+    >>> r.fragment
+    'target'
+
+And, the :func:`~urllib.parse.urlencode` function is now much more flexible,
+accepting either a string or bytes type for the *query* argument.  If it is a
+string, then the *safe*, *encoding*, and *error* parameters are sent to
+:func:`~urllib.parse.quote_plus` for encoding::
+
+    >>> urllib.parse.urlencode([
+             ('type', 'telenovela'),
+             ('name', '¿Dónde Está Elisa?')],
+             encoding='latin-1')
+    'type=telenovela&name=%BFD%F3nde+Est%E1+Elisa%3F'
+
+As detailed in :ref:`parsing-ascii-encoded-bytes`, all the :mod:`urllib.parse`
+functions now accept ASCII-encoded byte strings as input, so long as they are
+not mixed with regular strings.  If ASCII-encoded byte strings are given as
+parameters, the return types will also be an ASCII-encoded byte strings:
+
+    >>> urllib.parse.urlparse(b'http://www.python.org:80/about/')
+    ParseResultBytes(scheme=b'http', netloc=b'www.python.org:80',
+                     path=b'/about/', params=b'', query=b'', fragment=b'')

+
+mailbox
+-------
+
+Thanks to a concerted effort by R. David Murray, the :mod:`mailbox` module has
+been fixed for Python 3.2.  The challenge was that mailbox had been originally
+designed with a text interface, but email messages are best represented with
+:class:`bytes` because various parts of a message may have different encodings.
+
+The solution harnessed the :mod:`email` package's binary support for parsing
+arbitrary email messages.  In addition, the solution required a number of API
+changes.
+
+As expected, the :meth:`~mailbox.Mailbox.add` method for
+:class:`mailbox.Mailbox` objects now accepts binary input.
+
+:class:`~io.StringIO` and text file input are deprecated.  Also, string input
+will fail early if non-ASCII characters are used.  Previously it would fail when
+the email was processed in a later step.
+
+There is also support for binary output.  The :meth:`~mailbox.Mailbox.get_file`
+method now returns a file in the binary mode (where it used to incorrectly set
+the file to text-mode).  There is also a new :meth:`~mailbox.Mailbox.get_bytes`
+method that returns a :class:`bytes` representation of a message corresponding
+to a given *key*.
+
+It is still possible to get non-binary output using the old API's
+:meth:`~mailbox.Mailbox.get_string` method, but that approach
+is not very useful.  Instead, it is best to extract messages from
+a :class:`~mailbox.Message` object or to load them from binary input.
+

+initial patch by Victor Stinner in :issue:`9124`.)
+
+turtledemo
+----------
+
+The demonstration code for the :mod:`turtle` module was moved from the *Demo*
+directory to main library.  It includes over a dozen sample scripts with
+lively displays.  Being on :attr:`sys.path`, it can now be run directly
+from the command-line::
+
+    $ python -m turtledemo
+
+(Moved from the Demo directory by Alexander Belopolsky in :issue:`10199`.)
+
+Multi-threading
+===============
+
+* The mechanism for serializing execution of concurrently running Python threads
+  (generally known as the :term:`GIL` or :term:`Global Interpreter Lock`) has
+  been rewritten.  Among the objectives were more predictable switching
+  intervals and reduced overhead due to lock contention and the number of
+  ensuing system calls.  The notion of a "check interval" to allow thread
+  switches has been abandoned and replaced by an absolute duration expressed in
+  seconds.  This parameter is tunable through :func:`sys.setswitchinterval()`.
+  It currently defaults to 5 milliseconds.
+
+  Additional details about the implementation can be read from a `python-dev
+  mailing-list message
+  <http://mail.python.org/pipermail/python-dev/2009-October/093321.html>`_
+  (however, "priority requests" as exposed in this message have not been kept
+  for inclusion).
+
+  (Contributed by Antoine Pitrou.)
+
+* Regular and recursive locks now accept an optional *timeout* argument to their
+  :meth:`~threading.Lock.acquire` method.  (Contributed by Antoine Pitrou;
+  :issue:`7316`.)
+
+* Similarly, :meth:`threading.Semaphore.acquire` also gained a *timeout*
+  argument.  (Contributed by Torsten Landschoff; :issue:`850728`.)
+
+* Regular and recursive lock acquisitions can now be interrupted by signals on
+  platforms using Pthreads.  This means that Python programs that deadlock while
+  acquiring locks can be successfully killed by repeatedly sending SIGINT to the
+  process (by pressing :kbd:`Ctrl+C` in most shells).
+  (Contributed by Reid Kleckner; :issue:`8844`.)
+
+
+Optimizations
+=============
+
+A number of small performance enhancements have been added:
+
+* Python's peephole optimizer now recognizes patterns such ``x in {1, 2, 3}`` as
+  being a test for membership in a set of constants.  The optimizer recasts the
+  :class:`set` as a :class:`frozenset` and stores the pre-built constant.
+
+  Now that the speed penalty is gone, it is practical to start writing
+  membership tests using set-notation.  This style is both semantically clear
+  and operationally fast::
+
+      extension = name.rpartition('.')[2]
+      if extension in {'xml', 'html', 'xhtml', 'css'}:
+          handle(name)
+
+  (Patch and additional tests contributed by Dave Malcolm; :issue:`6690`).
+
+* Serializing and unserializing data using the :mod:`pickle` module is now
+  several times faster.
+
+  (Contributed by Alexandre Vassalotti, Antoine Pitrou
+  and the Unladen Swallow team in :issue:`9410` and :issue:`3873`.)
+
+* The `Timsort algorithm <http://en.wikipedia.org/wiki/Timsort>`_ used in
+  :meth:`list.sort` and :func:`sorted` now runs faster and uses less memory
+  when called with a :term:`key function`.  Previously, every element of
+  a list was wrapped with a temporary object that remembered the key value
+  associated with each element.  Now, two arrays of keys and values are
+  sorted in parallel.  This saves the memory consumed by the sort wrappers,
+  and it saves time lost to delegating comparisons.
+
+  (Patch by Daniel Stutzbach in :issue:`9915`.)
+
+* JSON decoding performance is improved and memory consumption is reduced
+  whenever the same string is repeated for multiple keys.  Also, JSON encoding
+  now uses the C speedups when the ``sort_keys`` argument is true.
+
+  (Contributed by Antoine Pitrou in :issue:`7451` and by Raymond Hettinger and
+  Antoine Pitrou in :issue:`10314`.)
+
+* Recursive locks (created with the :func:`threading.RLock` API) now benefit
+  from a C implementation which makes them as fast as regular locks, and between
+  10x and 15x faster than their previous pure Python implementation.
+
+  (Contributed by Antoine Pitrou; :issue:`3001`.)
+
+* The fast-search algorithm in stringlib is now used by the :meth:`split`,
+  :meth:`splitlines` and :meth:`replace` methods on
+  :class:`bytes`, :class:`bytearray` and :class:`str` objects. Likewise, the
+  algorithm is also used by :meth:`rfind`, :meth:`rindex`, :meth:`rsplit` and
+  :meth:`rpartition`.
+
+  (Patch by Florent Xicluna in :issue:`7622` and :issue:`7462`.)
+
+
+* String to integer conversions now work two "digits" at a time, reducing the
+  number of division and modulo operations.
+
+  (:issue:`6713` by Gawain Bolton, Mark Dickinson, and Victor Stinner.)
+
+There were several other minor optimizations. Set differencing now runs faster
+when one operand is much larger than the other (patch by Andress Bennetts in
+:issue:`8685`).  The :meth:`array.repeat` method has a faster implementation
+(:issue:`1569291` by Alexander Belopolsky). The :class:`BaseHTTPRequestHandler`
+has more efficient buffering (:issue:`3709` by Andrew Schaaf).  The
+:func:`operator.attrgetter` function has been sped-up (:issue:`10160` by
+Christos Georgiou).  And :class:`ConfigParser` loads multi-line arguments a bit
+faster (:issue:`7113` by �ukasz Langa).
+
+
+Unicode
+=======
+
+Python has been updated to `Unicode 6.0.0
+<http://unicode.org/versions/Unicode6.0.0/>`_.  The update to the standard adds
+over 2,000 new characters including `emoji <http://en.wikipedia.org/wiki/Emoji>`_
+symbols which are important for mobile phones.
+
+In addition, the updated standard has altered the character properties for two
+Kannada characters (U+0CF1, U+0CF2) and one New Tai Lue numeric character
+(U+19DA), making the former eligible for use in identifiers while disqualifying
+the latter.  For more information, see `Unicode Character Database Changes
+<http://www.unicode.org/versions/Unicode6.0.0/#Database_Changes>`_.
+
+
+Codecs
+======
+
+Support was added for *cp720* Arabic DOS encoding (:issue:`1616979`).
+
+MBCS encoding no longer ignores the error handler argument. In the default
+strict mode, it raises an :exc:`UnicodeDecodeError` when it encounters an
+undecodable byte sequence and an :exc:`UnicodeEncodeError` for an unencodable
+character.
+
+The MBCS codec supports ``'strict'`` and ``'ignore'`` error handlers for
+decoding, and ``'strict'`` and ``'replace'`` for encoding.
+
+To emulate Python3.1 MBCS encoding, select the ``'ignore'`` handler for decoding
+and the ``'replace'`` handler for encoding.
+
+On Mac OS X, Python decodes command line arguments with ``'utf-8'`` rather than
+the locale encoding.
+
+By default, :mod:`tarfile` uses ``'utf-8'`` encoding on Windows (instead of
+``'mbcs'``) and the ``'surrogateescape'`` error handler on all operating
+systems.
+
+
+Documentation
+=============
+
+The documentation continues to be improved.
+
+* A table of quick links has been added to the top of lengthy sections such as
+  :ref:`built-in-funcs`.  In the case of :mod:`itertools`, the links are
+  accompanied by tables of cheatsheet-style summaries to provide an overview and
+  memory jog without having to read all of the docs.
+
+* In some cases, the pure Python source code can be a helpful adjunct to the
+  documentation, so now many modules now feature quick links to the latest
+  version of the source code.  For example, the :mod:`functools` module
+  documentation has a quick link at the top labeled:
+
+    **Source code** :source:`Lib/functools.py`.
+
+  (Contributed by Raymond Hettinger; see
+  `rationale <http://rhettinger.wordpress.com/2011/01/28/open-your-source-more/>`_.)
+
+* The docs now contain more examples and recipes.  In particular, :mod:`re`
+  module has an extensive section, :ref:`re-examples`.  Likewise, the
+  :mod:`itertools` module continues to be updated with new
+  :ref:`itertools-recipes`.
+
+* The :mod:`datetime` module now has an auxiliary implementation in pure Python.
+  No functionality was changed.  This just provides an easier-to-read alternate
+  implementation.
+
+  (Contributed by Alexander Belopolsky in :issue:`9528`.)
+
+* The unmaintained :file:`Demo` directory has been removed.  Some demos were
+  integrated into the documentation, some were moved to the :file:`Tools/demo`
+  directory, and others were removed altogether.
+
+  (Contributed by Georg Brandl in :issue:`7962`.)
+
+
+IDLE
+====
+
+* The format menu now has an option to clean source files by stripping
+  trailing whitespace.
+
+  (Contributed by Raymond Hettinger; :issue:`5150`.)
+
+* IDLE on Mac OS X now works with both Carbon AquaTk and Cocoa AquaTk.

+
+Code Repository
+===============
+
+In addition to the existing Subversion code repository at http://svn.python.org
+there is now a `Mercurial <http://mercurial.selenic.com/>`_ repository at
+http://hg.python.org/\.
+
+After the 3.2 release, there are plans to switch to Mercurial as the primary
+repository.  This distributed version control system should make it easier for
+members of the community to create and share external changesets.  See
+:pep:`385` for details.
+
+To learn the new version control system, see the `tutorial by Joel
+Spolsky <http://hginit.com>`_ or the `Guide to Mercurial Workflows
+<http://mercurial.selenic.com/guide/>`_.
+
+
+Build and C API Changes
+=======================
+
+Changes to Python's build process and to the C API include:
+
+* The *idle*, *pydoc* and *2to3* scripts are now installed with a
+  version-specific suffix on ``make altinstall`` (:issue:`10679`).
+
+* The C functions that access the Unicode Database now accept and return
+  characters from the full Unicode range, even on narrow unicode builds
+  (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others).  A visible difference
+  in Python is that :func:`unicodedata.numeric` now returns the correct value
+  for large code points, and :func:`repr` may consider more characters as
+  printable.
+
+  (Reported by Bupjoe Lee and fixed by Amaury Forgeot D'Arc; :issue:`5127`.)
+
+* Computed gotos are now enabled by default on supported compilers (which are
+  detected by the configure script).  They can still be disabled selectively by
+  specifying ``--without-computed-gotos``.
+
+  (Contributed by Antoine Pitrou; :issue:`9203`.)
+
+* The option ``--with-wctype-functions`` was removed.  The built-in unicode
+  database is now used for all functions.
+
+  (Contributed by Amaury Forgeot D'Arc; :issue:`9210`.)
+
+* Hash values are now values of a new type, :c:type:`Py_hash_t`, which is
+  defined to be the same size as a pointer.  Previously they were of type long,
+  which on some 64-bit operating systems is still only 32 bits long.  As a
+  result of this fix, :class:`set` and :class:`dict` can now hold more than
+  ``2**32`` entries on builds with 64-bit pointers (previously, they could grow
+  to that size but their performance degraded catastrophically).
+
+  (Suggested by Raymond Hettinger and implemented by Benjamin Peterson;
+  :issue:`9778`.)
+
+* A new macro :c:macro:`Py_VA_COPY` copies the state of the variable argument
+  list.  It is equivalent to C99 *va_copy* but available on all Python platforms
+  (:issue:`2443`).
+
+* A new C API function :c:func:`PySys_SetArgvEx` allows an embedded interpreter
+  to set :attr:`sys.argv` without also modifying :attr:`sys.path`
+  (:issue:`5753`).
+
+* :c:macro:`PyEval_CallObject` is now only available in macro form.  The
+  function declaration, which was kept for backwards compatibility reasons, is
+  now removed -- the macro was introduced in 1997 (:issue:`8276`).
+
+* There is a new function :c:func:`PyLong_AsLongLongAndOverflow` which
+  is analogous to :c:func:`PyLong_AsLongAndOverflow`.  They both serve to
+  convert Python :class:`int` into a native fixed-width type while providing
+  detection of cases where the conversion won't fit (:issue:`7767`).
+
+* The :c:func:`PyUnicode_CompareWithASCIIString` function now returns *not
+  equal* if the Python string is *NUL* terminated.
+
+* There is a new function :c:func:`PyErr_NewExceptionWithDoc` that is
+  like :c:func:`PyErr_NewException` but allows a docstring to be specified.
+  This lets C exceptions have the same self-documenting capabilities as
+  their pure Python counterparts (:issue:`7033`).
+
+* When compiled with the ``--with-valgrind`` option, the pymalloc
+  allocator will be automatically disabled when running under Valgrind.  This
+  gives improved memory leak detection when running under Valgrind, while taking
+  advantage of pymalloc at other times (:issue:`2422`).
+
+* Removed the ``O?`` format from the *PyArg_Parse* functions.  The format is no
+  longer used and it had never been documented (:issue:`8837`).
+
+There were a number of other small changes to the C-API.  See the
+:source:`Misc/NEWS` file for a complete list.
+
+Also, there were a number of updates to the Mac OS X build, see
+:source:`Mac/BuildScript/README.txt` for details.  For users running a 32/64-bit
+build, there is a known problem with the default Tcl/Tk on Mac OS X 10.6.
+Accordingly, we recommend installing an updated alternative such as
+`ActiveState Tcl/Tk 8.5.9 <http://www.activestate.com/activetcl/downloads>`_\.
+See http://www.python.org/download/mac/tcltk/ for additional details.
+
+Porting to Python 3.2
+=====================
+
+This section lists previously described changes and other bugfixes that may
+require changes to your code:
+
+* The :mod:`configparser` module has a number of clean-ups.  The major change is
+  to replace the old :class:`ConfigParser` class with long-standing preferred
+  alternative :class:`SafeConfigParser`.  In addition there are a number of
+  smaller incompatibilities:
+
+  * The interpolation syntax is now validated on
+    :meth:`~configparser.ConfigParser.get` and
+    :meth:`~configparser.ConfigParser.set` operations. In the default
+    interpolation scheme, only two tokens with percent signs are valid: ``%(name)s``
+    and ``%%``, the latter being an escaped percent sign.
+
+  * The :meth:`~configparser.ConfigParser.set` and
+    :meth:`~configparser.ConfigParser.add_section` methods now verify that
+    values are actual strings.  Formerly, unsupported types could be introduced
+    unintentionally.
+
+  * Duplicate sections or options from a single source now raise either
+    :exc:`~configparser.DuplicateSectionError` or
+    :exc:`~configparser.DuplicateOptionError`.  Formerly, duplicates would
+    silently overwrite a previous entry.
+
+  * Inline comments are now disabled by default so now the **;** character
+    can be safely used in values.
+
+  * Comments now can be indented.  Consequently, for **;** or **#** to appear at
+    the start of a line in multiline values, it has to be interpolated.  This
+    keeps comment prefix characters in values from being mistaken as comments.
+
+  * ``""`` is now a valid value and is no longer automatically converted to an
+    empty string. For empty strings, use ``"option ="`` in a line.
+
+* The :mod:`nntplib` module was reworked extensively, meaning that its APIs
+  are often incompatible with the 3.1 APIs.
+
+* :class:`bytearray` objects can no longer be used as filenames; instead,
+  they should be converted to :class:`bytes`.
+
+* The :meth:`array.tostring` and :meth:`array.fromstring` have been renamed to
+  :meth:`array.tobytes` and :meth:`array.frombytes` for clarity.  The old names
+  have been deprecated. (See :issue:`8990`.)
+
+* ``PyArg_Parse*()`` functions:
+
+  * "t#" format has been removed: use "s#" or "s*" instead
+  * "w" and "w#" formats has been removed: use "w*" instead
+
+* The :c:type:`PyCObject` type, deprecated in 3.1, has been removed.  To wrap
+  opaque C pointers in Python objects, the :c:type:`PyCapsule` API should be used
+  instead; the new type has a well-defined interface for passing typing safety
+  information and a less complicated signature for calling a destructor.
+
+* The :func:`sys.setfilesystemencoding` function was removed because
+  it had a flawed design.
+
+* The :func:`random.seed` function and method now salt string seeds with an
+  sha512 hash function.  To access the previous version of *seed* in order to
+  reproduce Python 3.1 sequences, set the *version* argument to *1*,
+  ``random.seed(s, version=1)``.
+
+* The previously deprecated :func:`string.maketrans` function has been removed
+  in favor of the static methods :meth:`bytes.maketrans` and
+  :meth:`bytearray.maketrans`.  This change solves the confusion around which
+  types were supported by the :mod:`string` module.  Now, :class:`str`,
+  :class:`bytes`, and :class:`bytearray` each have their own **maketrans** and
+  **translate** methods with intermediate translation tables of the appropriate
+  type.
+
+  (Contributed by Georg Brandl; :issue:`5675`.)
+
+* The previously deprecated :func:`contextlib.nested` function has been removed
+  in favor of a plain :keyword:`with` statement which can accept multiple
+  context managers.  The latter technique is faster (because it is built-in),
+  and it does a better job finalizing multiple context managers when one of them
+  raises an exception::
+
+    with open('mylog.txt') as infile, open('a.out', 'w') as outfile:
+        for line in infile:
+            if '<critical>' in line:
+                outfile.write(line)
+
+  (Contributed by Georg Brandl and Mattias Brändström;
+  `appspot issue 53094 <http://codereview.appspot.com/53094>`_.)
+
+* :func:`struct.pack` now only allows bytes for the ``s`` string pack code.
+  Formerly, it would accept text arguments and implicitly encode them to bytes
+  using UTF-8.  This was problematic because it made assumptions about the
+  correct encoding and because a variable-length encoding can fail when writing
+  to fixed length segment of a structure.
+
+  Code such as ``struct.pack('<6sHHBBB', 'GIF87a', x, y)`` should be rewritten
+  with to use bytes instead of text, ``struct.pack('<6sHHBBB', b'GIF87a', x, y)``.
+
+  (Discovered by David Beazley and fixed by Victor Stinner; :issue:`10783`.)
+
+* The :class:`xml.etree.ElementTree` class now raises an
+  :exc:`xml.etree.ElementTree.ParseError` when a parse fails. Previously it
+  raised a :exc:`xml.parsers.expat.ExpatError`.
+
+* The new, longer :func:`str` value on floats may break doctests which rely on
+  the old output format.
+
+* In :class:`subprocess.Popen`, the default value for *close_fds* is now
+  ``True`` under Unix; under Windows, it is ``True`` if the three standard
+  streams are set to ``None``, ``False`` otherwise.  Previously, *close_fds*
+  was always ``False`` by default, which produced difficult to solve bugs
+  or race conditions when open file descriptors would leak into the child
+  process.
+
+* Support for legacy HTTP 0.9 has been removed from :mod:`urllib.request`
+  and :mod:`http.client`.  Such support is still present on the server side
+  (in :mod:`http.server`).
+
+  (Contributed by Antoine Pitrou, :issue:`10711`.)
+
+* SSL sockets in timeout mode now raise :exc:`socket.timeout` when a timeout
+  occurs, rather than a generic :exc:`~ssl.SSLError`.
+
+  (Contributed by Antoine Pitrou, :issue:`10272`.)
+
+* The misleading functions :c:func:`PyEval_AcquireLock()` and
+  :c:func:`PyEval_ReleaseLock()` have been officially deprecated.  The
+  thread-state aware APIs (such as :c:func:`PyEval_SaveThread()`
+  and :c:func:`PyEval_RestoreThread()`) should be used instead.
+
+* Due to security risks, :func:`asyncore.handle_accept` has been deprecated, and
+  a new function, :func:`asyncore.handle_accepted`, was added to replace it.
+
+  (Contributed by Giampaolo Rodola in :issue:`6706`.)
+
+* Due to the new :term:`GIL` implementation, :c:func:`PyEval_InitThreads()`
+  cannot be called before :c:func:`Py_Initialize()` anymore.

+/* This file defines dynamic annotations for use with dynamic analysis
+   tool such as valgrind, PIN, etc.
+
+   Dynamic annotation is a source code annotation that affects
+   the generated code (that is, the annotation is not a comment).
+   Each such annotation is attached to a particular
+   instruction and/or to a particular object (address) in the program.
+
+   The annotations that should be used by users are macros in all upper-case
+   (e.g., _Py_ANNOTATE_NEW_MEMORY).
+
+   Actual implementation of these macros may differ depending on the
+   dynamic analysis tool being used.
+
+   See http://code.google.com/p/data-race-test/  for more information.
+
+   This file supports the following dynamic analysis tools:
+   - None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
+      Macros are defined empty.
+   - ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
+      Macros are defined as calls to non-inlinable empty functions
+      that are intercepted by Valgrind. */

+     Annotations useful when implementing condition variables such as CondVar,
+     using conditional critical sections (Await/LockWhen) and when constructing
+     user-defined synchronization mechanisms.
+
+     The annotations _Py_ANNOTATE_HAPPENS_BEFORE() and
+     _Py_ANNOTATE_HAPPENS_AFTER() can be used to define happens-before arcs in
+     user-defined synchronization mechanisms: the race detector will infer an
+     arc from the former to the latter when they share the same argument
+     pointer.
+
+     Example 1 (reference counting):
+
+     void Unref() {
+       _Py_ANNOTATE_HAPPENS_BEFORE(&refcount_);
+       if (AtomicDecrementByOne(&refcount_) == 0) {
+         _Py_ANNOTATE_HAPPENS_AFTER(&refcount_);
+         delete this;
+       }
+     }
+
+     Example 2 (message queue):
+
+     void MyQueue::Put(Type *e) {
+       MutexLock lock(&mu_);
+       _Py_ANNOTATE_HAPPENS_BEFORE(e);
+       PutElementIntoMyQueue(e);
+     }
+
+     Type *MyQueue::Get() {
+       MutexLock lock(&mu_);
+       Type *e = GetElementFromMyQueue();
+       _Py_ANNOTATE_HAPPENS_AFTER(e);
+       return e;
+     }
+
+     Note: when possible, please use the existing reference counting and message
+     queue implementations instead of inventing new ones. */

+"""Command-line parsing library
+
+This module is an optparse-inspired command-line parsing library that:
+
+    - handles both optional and positional arguments
+    - produces highly informative usage messages
+    - supports parsers that dispatch to sub-parsers
+
+The following is a simple usage example that sums integers from the
+command-line and writes the result to a file::
+
+    parser = argparse.ArgumentParser(
+        description='sum the integers at the command line')
+    parser.add_argument(
+        'integers', metavar='int', nargs='+', type=int,
+        help='an integer to be summed')
+    parser.add_argument(
+        '--log', default=sys.stdout, type=argparse.FileType('w'),
+        help='the file where the sum should be written')
+    args = parser.parse_args()
+    args.log.write('%s' % sum(args.integers))
+    args.log.close()
+
+The module contains the following public classes:
+
+    - ArgumentParser -- The main entry point for command-line parsing. As the
+        example above shows, the add_argument() method is used to populate
+        the parser with actions for optional and positional arguments. Then
+        the parse_args() method is invoked to convert the args at the
+        command-line into an object with attributes.
+
+    - ArgumentError -- The exception raised by ArgumentParser objects when
+        there are errors with the parser's actions. Errors raised while
+        parsing the command-line are caught by ArgumentParser and emitted
+        as command-line messages.
+
+    - FileType -- A factory for defining types of files to be created. As the
+        example above shows, instances of FileType are typically passed as
+        the type= argument of add_argument() calls.
+
+    - Action -- The base class for parser actions. Typically actions are
+        selected by passing strings like 'store_true' or 'append_const' to
+        the action= argument of add_argument(). However, for greater
+        customization of ArgumentParser actions, subclasses of Action may
+        be defined and passed as the action= argument.
+
+    - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter,
+        ArgumentDefaultsHelpFormatter -- Formatter classes which
+        may be passed as the formatter_class= argument to the
+        ArgumentParser constructor. HelpFormatter is the default,
+        RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser
+        not to change the formatting for help text, and
+        ArgumentDefaultsHelpFormatter adds information about argument defaults
+        to the help.
+
+All other classes in this module are considered implementation details.
+(Also note that HelpFormatter and RawDescriptionHelpFormatter are only
+considered public as object names -- the API of the formatter objects is
+still considered an implementation detail.)

+
+        - nargs -- The number of command-line arguments that should be
+            consumed. By default, one argument will be consumed and a single
+            value will be produced.  Other values include:
+                - N (an integer) consumes N arguments (and produces a list)
+                - '?' consumes zero or one arguments
+                - '*' consumes zero or more arguments (and produces a list)
+                - '+' consumes one or more arguments (and produces a list)
+            Note that the difference between the default and nargs=1 is that
+            with the default, a single value will be produced, while with
+            nargs=1, a list containing a single value will be produced.
+
+        - const -- The value to be produced if the option is specified and the
+            option uses an action that takes no values.
+
+        - default -- The value to be produced if the option is not specified.
+
+        - type -- The type which the command-line arguments should be converted
+            to, should be one of 'string', 'int', 'float', 'complex' or a
+            callable object that accepts a single string argument. If None,
+            'string' is assumed.
+
+        - choices -- A container of values that should be allowed. If not None,
+            after a command-line argument has been converted to the appropriate
+            type, an exception will be raised if it is not a member of this
+            collection.
+
+        - required -- True if the action must always be specified at the
+            command line. This is only meaningful for optional command-line
+            arguments.
+
+        - help -- The help string describing the argument.
+
+        - metavar -- The name to be used for the option's argument with the

-The option values can contain format strings which refer to other values in
-the same section, or values in a special [DEFAULT] section.
-
-For example:
-
-    something: %(dir)s/whatever

 Intrinsic defaults can be specified by passing them into the
 ConfigParser constructor as a dictionary.
 
 class:
 
 ConfigParser -- responsible for parsing a list of

+                    configuration files, and managing the parsed database.
 
     methods:
 
-    __init__(defaults=None)
-        create the parser and specify a dictionary of intrinsic defaults.  The
-        keys must be strings, the values must be appropriate for %()s string
-        interpolation.  Note that `__name__' is always an intrinsic default;
-        its value is the section's name.
+    __init__(defaults=None, dict_type=_default_dict, allow_no_value=False,
+             delimiters=('=', ':'), comment_prefixes=('#', ';'),
+             inline_comment_prefixes=None, strict=True,
+             empty_lines_in_values=True):
+        Create the parser. When `defaults' is given, it is initialized into the
+        dictionary or intrinsic defaults. The keys must be strings, the values
+        must be appropriate for %()s string interpolation.
+
+        When `dict_type' is given, it will be used to create the dictionary
+        objects for the list of sections, for the options within a section, and
+        for the default values.
+
+        When `delimiters' is given, it will be used as the set of substrings
+        that divide keys from values.
+
+        When `comment_prefixes' is given, it will be used as the set of
+        substrings that prefix comments in empty lines. Comments can be
+        indented.
+
+        When `inline_comment_prefixes' is given, it will be used as the set of
+        substrings that prefix comments in non-empty lines.
+
+        When `strict` is True, the parser won't allow for any section or option
+        duplicates while reading from a single source (file, string or
+        dictionary). Default is True.
+
+        When `empty_lines_in_values' is False (default: True), each empty line
+        marks the end of an option. Otherwise, internal empty lines of
+        a multiline option are kept as part of the value.
+
+        When `allow_no_value' is True (default: False), options without
+        values are accepted; the value presented for these is None.
 
     sections()

+        Read and parse the list of named configuration files, given by
         name.  A single filename is also allowed.  Non-existing files
         are ignored.  Return list of successfully read files.
 
-    readfp(fp, filename=None)
-        read and parse one configuration file, given as a file object.
-        The filename defaults to fp.name; it is only used in error
-        messages (if fp has no `name' attribute, the string `<???>' is used).

+        converted to strings.
+
+    get(section, option, raw=False, vars=None, fallback=_UNSET)
+        Return a string value for the named option.  All % interpolations are
         expanded in the return values, based on the defaults passed into the
         constructor and the DEFAULT section.  Additional substitutions may be
         provided using the `vars' argument, which must be a dictionary whose

-    items(section, raw=False, vars=None)
+    items(section=_UNSET, raw=False, vars=None)
+        If section is given, return a list of tuples with (section_name,

+Some time zone algebra.  For a datetime x, let
+    x.n = x stripped of its timezone -- its naive time.
+    x.o = x.utcoffset(), and assuming that doesn't raise an exception or
+          return None
+    x.d = x.dst(), and assuming that doesn't raise an exception or
+          return None
+    x.s = x's standard offset, x.o - x.d
+
+Now some derived rules, where k is a duration (timedelta).
+
+1. x.o = x.s + x.d
+   This follows from the definition of x.s.
+
+2. If x and y have the same tzinfo member, x.s = y.s.
+   This is actually a requirement, an assumption we need to make about
+   sane tzinfo classes.
+
+3. The naive UTC time corresponding to x is x.n - x.o.
+   This is again a requirement for a sane tzinfo class.
+
+4. (x+k).s = x.s
+   This follows from #2, and that datimetimetz+timedelta preserves tzinfo.
+
+5. (x+k).n = x.n + k
+   Again follows from how arithmetic is defined.
+
+Now we can explain tz.fromutc(x).  Let's assume it's an interesting case
+(meaning that the various tzinfo methods exist, and don't blow up or return
+None when called).
+
+The function wants to return a datetime y with timezone tz, equivalent to x.
+x is already in UTC.
+
+By #3, we want
+
+    y.n - y.o = x.n                             [1]
+
+The algorithm starts by attaching tz to x.n, and calling that y.  So
+x.n = y.n at the start.  Then it wants to add a duration k to y, so that [1]
+becomes true; in effect, we want to solve [2] for k:
+
+   (y+k).n - (y+k).o = x.n                      [2]
+
+By #1, this is the same as
+
+   (y+k).n - ((y+k).s + (y+k).d) = x.n          [3]
+
+By #5, (y+k).n = y.n + k, which equals x.n + k because x.n=y.n at the start.
+Substituting that into [3],
+
+   x.n + k - (y+k).s - (y+k).d = x.n; the x.n terms cancel, leaving
+   k - (y+k).s - (y+k).d = 0; rearranging,
+   k = (y+k).s - (y+k).d; by #4, (y+k).s == y.s, so
+   k = y.s - (y+k).d
+
+On the RHS, (y+k).d can't be computed directly, but y.s can be, and we
+approximate k by ignoring the (y+k).d term at first.  Note that k can't be
+very large, since all offset-returning methods return a duration of magnitude
+less than 24 hours.  For that reason, if y is firmly in std time, (y+k).d must
+be 0, so ignoring it has no consequence then.
+
+In any case, the new value is
+
+    z = y + y.s                                 [4]
+
+It's helpful to step back at look at [4] from a higher level:  it's simply
+mapping from UTC to tz's standard time.
+
+At this point, if
+
+    z.n - z.o = x.n                             [5]
+
+we have an equivalent time, and are almost done.  The insecurity here is
+at the start of daylight time.  Picture US Eastern for concreteness.  The wall
+time jumps from 1:59 to 3:00, and wall hours of the form 2:MM don't make good
+sense then.  The docs ask that an Eastern tzinfo class consider such a time to
+be EDT (because it's "after 2"), which is a redundant spelling of 1:MM EST
+on the day DST starts.  We want to return the 1:MM EST spelling because that's
+the only spelling that makes sense on the local wall clock.
+
+In fact, if [5] holds at this point, we do have the standard-time spelling,
+but that takes a bit of proof.  We first prove a stronger result.  What's the
+difference between the LHS and RHS of [5]?  Let
+
+    diff = x.n - (z.n - z.o)                    [6]
+
+Now
+    z.n =                       by [4]
+    (y + y.s).n =               by #5
+    y.n + y.s =                 since y.n = x.n
+    x.n + y.s =                 since z and y are have the same tzinfo member,
+                                    y.s = z.s by #2
+    x.n + z.s
+
+Plugging that back into [6] gives
+
+    diff =
+    x.n - ((x.n + z.s) - z.o) =     expanding
+    x.n - x.n - z.s + z.o =         cancelling
+    - z.s + z.o =                   by #2
+    z.d
+
+So diff = z.d.
+
+If [5] is true now, diff = 0, so z.d = 0 too, and we have the standard-time
+spelling we wanted in the endcase described above.  We're done.  Contrarily,
+if z.d = 0, then we have a UTC equivalent, and are also done.
+
+If [5] is not true now, diff = z.d != 0, and z.d is the offset we need to
+add to z (in effect, z is in tz's standard time, and we need to shift the
+local clock into tz's daylight time).
+
+Let
+
+    z' = z + z.d = z + diff                     [7]
+
+and we can again ask whether
+
+    z'.n - z'.o = x.n                           [8]
+
+If so, we're done.  If not, the tzinfo class is insane, according to the
+assumptions we've made.  This also requires a bit of proof.  As before, let's
+compute the difference between the LHS and RHS of [8] (and skipping some of
+the justifications for the kinds of substitutions we've done several times
+already):
+
+    diff' = x.n - (z'.n - z'.o) =           replacing z'.n via [7]
+            x.n  - (z.n + diff - z'.o) =    replacing diff via [6]
+            x.n - (z.n + x.n - (z.n - z.o) - z'.o) =
+            x.n - z.n - x.n + z.n - z.o + z'.o =    cancel x.n
+            - z.n + z.n - z.o + z'.o =              cancel z.n
+            - z.o + z'.o =                      #1 twice
+            -z.s - z.d + z'.s + z'.d =          z and z' have same tzinfo
+            z'.d - z.d
+
+So z' is UTC-equivalent to x iff z'.d = z.d at this point.  If they are equal,
+we've found the UTC-equivalent so are done.  In fact, we stop with [7] and
+return z', not bothering to compute z'.d.
+
+How could z.d and z'd differ?  z' = z + z.d [7], so merely moving z' by
+a dst() offset, and starting *from* a time already in DST (we know z.d != 0),
+would have to change the result dst() returns:  we start in DST, and moving
+a little further into it takes us out of DST.
+
+There isn't a sane case where this can happen.  The closest it gets is at
+the end of DST, where there's an hour in UTC with no spelling in a hybrid
+tzinfo class.  In US Eastern, that's 5:MM UTC = 0:MM EST = 1:MM EDT.  During
+that hour, on an Eastern clock 1:MM is taken as being in standard time (6:MM
+UTC) because the docs insist on that, but 0:MM is taken as being in daylight
+time (4:MM UTC).  There is no local time mapping to 5:MM UTC.  The local
+clock jumps from 1:59 back to 1:00 again, and repeats the 1:MM hour in
+standard time.  Since that's what the local clock *does*, we want to map both
+UTC hours 5:MM and 6:MM to 1:MM Eastern.  The result is ambiguous
+in local time, but so it goes -- it's the way the local clock works.
+
+When x = 5:MM UTC is the input to this algorithm, x.o=0, y.o=-5 and y.d=0,
+so z=0:MM.  z.d=60 (minutes) then, so [5] doesn't hold and we keep going.
+z' = z + z.d = 1:MM then, and z'.d=0, and z'.d - z.d = -60 != 0 so [8]
+(correctly) concludes that z' is not UTC-equivalent to x.
+
+Because we know z.d said z was in daylight time (else [5] would have held and
+we would have stopped then), and we know z.d != z'.d (else [8] would have held
+and we we have stopped then), and there are only 2 possible values dst() can
+return in Eastern, it follows that z'.d must be 0 (which it is in the example,
+but the reasoning doesn't depend on the example -- it depends on there being
+two possible dst() outcomes, one zero and the other non-zero).  Therefore
+z' must be in standard time, and is the spelling we want in this case.
+
+Note again that z' is not UTC-equivalent as far as the hybrid tzinfo class is
+concerned (because it takes z' as being in standard time rather than the
+daylight time we intend here), but returning it gives the real-life "local
+clock repeats an hour" behavior when mapping the "unspellable" UTC hour into
+tz.
+
+When the input is 6:MM, z=1:MM and z.d=0, and we stop at once, again with
+the 1:MM standard time spelling we want.
+
+So how can this break?  One of the assumptions must be violated.  Two
+possibilities:
+
+1) [2] effectively says that y.s is invariant across all y belong to a given
+   time zone.  This isn't true if, for political reasons or continental drift,
+   a region decides to change its base offset from UTC.
+
+2) There may be versions of "double daylight" time where the tail end of
+   the analysis gives up a step too early.  I haven't thought about that
+   enough to say.
+
+In any case, it's clear that the default fromutc() is strong enough to handle
+"almost all" time zones:  so long as the standard offset is invariant, it
+doesn't matter if daylight time transition points change from year to year, or
+if daylight time is skipped in some years; it doesn't matter how large or
+small dst() may get within its bounds; and it doesn't even matter if some
+perverse time zone returns a negative dst()).  So a breaking case must be
+pretty bizarre, and a tzinfo subclass can override fromutc() if it is.

-The Python Debugger Pdb
-=======================
-
-To use the debugger in its simplest form:
-
-        >>> import pdb
-        >>> pdb.run('<a statement>')
-
-The debugger's prompt is '(Pdb) '.  This will stop in the first
-function call in <a statement>.
-
-Alternatively, if a statement terminated with an unhandled exception,
-you can use pdb's post-mortem facility to inspect the contents of the
-traceback:
-
-        >>> <a statement>
-        <exception traceback>
-        >>> import pdb
-        >>> pdb.pm()
-
-The commands recognized by the debugger are listed in the next
-section.  Most can be abbreviated as indicated; e.g., h(elp) means
-that 'help' can be typed as 'h' or 'help' (but not as 'he' or 'hel',
-nor as 'H' or 'Help' or 'HELP').  Optional arguments are enclosed in
-square brackets.
-
-A blank line repeats the previous command literally, except for
-'list', where it lists the next 11 lines.
-
-Commands that the debugger doesn't recognize are assumed to be Python
-statements and are executed in the context of the program being
-debugged.  Python statements can also be prefixed with an exclamation
-point ('!').  This is a powerful way to inspect the program being
-debugged; it is even possible to change variables.  When an exception
-occurs in such a statement, the exception name is printed but the
-debugger's state is not changed.
-
-The debugger supports aliases, which can save typing.  And aliases can
-have parameters (see the alias help entry) which allows one a certain
-level of adaptability to the context under examination.
-
-Multiple commands may be entered on a single line, separated by the
-pair ';;'.  No intelligence is applied to separating the commands; the
-input is split at the first ';;', even if it is in the middle of a
-quoted string.
-
-If a file ".pdbrc" exists in your home directory or in the current
-directory, it is read in and executed as if it had been typed at the
-debugger prompt.  This is particularly useful for aliases.  If both
-files exist, the one in the home directory is read first and aliases
-defined there can be overriden by the local file.
-
-Aside from aliases, the debugger is not directly programmable; but it
-is implemented as a class from which you can derive your own debugger
-class, which you can make as fancy as you like.
-
-
-Debugger commands
-=================
-
-h(elp)
-        Without argument, print the list of available commands.  With
-        a command name as argument, print help about that command
-        (this is currently not implemented).
-
-w(here)
-        Print a stack trace, with the most recent frame at the bottom.
-        An arrow indicates the "current frame", which determines the
-        context of most commands.
-
-d(own)
-        Move the current frame one level down in the stack trace
-        (to a newer frame).
-
-u(p)
-        Move the current frame one level up in the stack trace
-        (to an older frame).
-
-b(reak) [ ([filename:]lineno | function) [, condition] ]
-        With a filename:line number argument, set a break there.  If
-        filename is omitted, use the current file.  With a function
-        name, set a break at the first executable line of that
-        function.  Without argument, list all breaks.  Each breakpoint
-        is assigned a number to which all the other breakpoint
-        commands refer.
-
-        The condition argument, if present, is a string which must
-        evaluate to true in order for the breakpoint to be honored.
-
-tbreak [ ([filename:]lineno | function) [, condition] ]
-        Temporary breakpoint, which is removed automatically when it
-        is first hit.  The arguments are the same as break.
-
-cl(ear) [bpnumber [bpnumber ...] ]
-        With a space separated list of breakpoint numbers, clear those
-        breakpoints.  Without argument, clear all breaks (but first
-        ask confirmation).
-
-disable bpnumber [bpnumber ...]
-        Disables the breakpoints given as a space separated list of
-        breakpoint numbers.  Disabling a breakpoint means it cannot
-        cause the program to stop execution, but unlike clearing a
-        breakpoint, it remains in the list of breakpoints and can be
-        (re-)enabled.
-
-enable bpnumber [bpnumber ...]
-        Enables the breakpoints specified.
-
-ignore bpnumber count
-        Sets the ignore count for the given breakpoint number.  If
-        count is omitted, the ignore count is set to 0.  A breakpoint
-        becomes active when the ignore count is zero.  When non-zero,
-        the count is decremented each time the breakpoint is reached
-        and the breakpoint is not disabled and any associated
-        condition evaluates to true.
-
-condition bpnumber condition
-        condition is an expression which must evaluate to true before
-        the breakpoint is honored.  If condition is absent, any
-        existing condition is removed; i.e., the breakpoint is made
-        unconditional.
-
-s(tep)
-        Execute the current line, stop at the first possible occasion
-        (either in a function that is called or in the current function).
-
-n(ext)
-        Continue execution until the next line in the current function
-        is reached or it returns.
-
-unt(il)
-        Continue execution until the line with a number greater than the 
-        current one is reached or until the current frame returns.
-
-r(eturn)
-        Continue execution until the current function returns.
-
-run [args...]
-        Restart the debugged python program. If a string is supplied it is
-        splitted with "shlex", and the result is used as the new sys.argv.
-	History, breakpoints, actions and debugger options are preserved.
-	"restart" is an alias for "run".
-
-c(ont(inue))
-        Continue execution, only stop when a breakpoint is encountered.
-
-l(ist) [first [,last]]
-        List source code for the current file.
-        Without arguments, list 11 lines around the current line
-        or continue the previous listing.
-        With one argument, list 11 lines starting at that line.
-        With two arguments, list the given range;
-        if the second argument is less than the first, it is a count.
-
-a(rgs)
-        Print the argument list of the current function.
-
-p expression
-        Print the value of the expression.
-
-(!) statement
-        Execute the (one-line) statement in the context of the current
-        stack frame.  The exclamation point can be omitted unless the
-        first word of the statement resembles a debugger command.  To
-        assign to a global variable you must always prefix the command
-        with a 'global' command, e.g.:
-        (Pdb) global list_options; list_options = ['-l']
-        (Pdb)
-
-
-whatis arg
-         Prints the type of the argument.
-
-alias [name [command]]
-        Creates an alias called 'name' that executes 'command'.  The
-        command must *not* be enclosed in quotes.  Replaceable
-        parameters can be indicated by %1, %2, and so on, while %* is
-        replaced by all the parameters.  If no command is given, the
-        current alias for name is shown. If no name is given, all
-        aliases are listed.
-
-        Aliases may be nested and can contain anything that can be
-        legally typed at the pdb prompt.  Note!  You *can* override
-        internal pdb commands with aliases!  Those internal commands
-        are then hidden until the alias is removed.  Aliasing is
-        recursively applied to the first word of the command line; all
-        other words in the line are left alone.
-
-        As an example, here are two useful aliases (especially when
-        placed in the .pdbrc file):
-
-        #Print instance variables (usage "pi classInst")
-        alias pi for k in %1.__dict__.keys(): print "%1.",k,"=",%1.__dict__[k]
-        #Print instance variables in self
-        alias ps pi self
-                
-unalias name
-        Deletes the specified alias.
-
-q(uit)
-        Quit from the debugger.
-        The program being executed is aborted.

 topics = {'assert': '\nThe ``assert`` statement\n************************\n\nAssert statements are a convenient way to insert debugging assertions\ninto a program:\n\n   assert_stmt ::= "assert" expression ["," expression]\n\nThe simple form, ``assert expression``, is equivalent to\n\n   if __debug__:\n      if not expression: raise AssertionError\n\nThe extended form, ``assert expression1, expression2``, is equivalent\nto\n\n   if __debug__:\n      if not expression1: raise AssertionError(expression2)\n\nThese equivalences assume that ``__debug__`` and ``AssertionError``\nrefer to the built-in variables with those names.  In the current\nimplementation, the built-in variable ``__debug__`` is ``True`` under\nnormal circumstances, ``False`` when optimization is requested\n(command line option -O).  The current code generator emits no code\nfor an assert statement when optimization is requested at compile\ntime.  Note that it is unnecessary to include the source code for the\nexpression that failed in the error message; it will be displayed as\npart of the stack trace.\n\nAssignments to ``__debug__`` are illegal.  The value for the built-in\nvariable is determined when the interpreter starts.\n',
- 'assignment': '\nAssignment statements\n*********************\n\nAssignment statements are used to (re)bind names to values and to\nmodify attributes or items of mutable objects:\n\n   assignment_stmt ::= (target_list "=")+ (expression_list | yield_expression)\n   target_list     ::= target ("," target)* [","]\n   target          ::= identifier\n              | "(" target_list ")"\n              | "[" target_list "]"\n              | attributeref\n              | subscription\n              | slicing\n              | "*" target\n\n(See section *Primaries* for the syntax definitions for the last three\nsymbols.)\n\nAn assignment statement evaluates the expression list (remember that\nthis can be a single expression or a comma-separated list, the latter\nyielding a tuple) and assigns the single resulting object to each of\nthe target lists, from left to right.\n\nAssignment is defined recursively depending on the form of the target\n(list). When a target is part of a mutable object (an attribute\nreference, subscription or slicing), the mutable object must\nultimately perform the assignment and decide about its validity, and\nmay raise an exception if the assignment is unacceptable.  The rules\nobserved by various types and the exceptions raised are given with the\ndefinition of the object types (see section *The standard type\nhierarchy*).\n\nAssignment of an object to a target list, optionally enclosed in\nparentheses or square brackets, is recursively defined as follows.\n\n* If the target list is a single target: The object is assigned to\n  that target.\n\n* If the target list is a comma-separated list of targets: The object\n  must be an iterable with the same number of items as there are\n  targets in the target list, and the items are assigned, from left to\n  right, to the corresponding targets. (This rule is relaxed as of\n  Python 1.5; in earlier versions, the object had to be a tuple.\n  Since strings are sequences, an assignment like ``a, b = "xy"`` is\n  now legal as long as the string has the right length.)\n\n  * If the target list contains one target prefixed with an asterisk,\n    called a "starred" target: The object must be a sequence with at\n    least as many items as there are targets in the target list, minus\n    one.  The first items of the sequence are assigned, from left to\n    right, to the targets before the starred target.  The final items\n    of the sequence are assigned to the targets after the starred\n    target.  A list of the remaining items in the sequence is then\n    assigned to the starred target (the list can be empty).\n\n  * Else: The object must be a sequence with the same number of items\n    as there are targets in the target list, and the items are\n    assigned, from left to right, to the corresponding targets.\n\nAssignment of an object to a single target is recursively defined as\nfollows.\n\n* If the target is an identifier (name):\n\n  * If the name does not occur in a ``global`` or ``nonlocal``\n    statement in the current code block: the name is bound to the\n    object in the current local namespace.\n\n  * Otherwise: the name is bound to the object in the global namespace\n    or the outer namespace determined by ``nonlocal``, respectively.\n\n  The name is rebound if it was already bound.  This may cause the\n  reference count for the object previously bound to the name to reach\n  zero, causing the object to be deallocated and its destructor (if it\n  has one) to be called.\n\n  The name is rebound if it was already bound.  This may cause the\n  reference count for the object previously bound to the name to reach\n  zero, causing the object to be deallocated and its destructor (if it\n  has one) to be called.\n\n* If the target is a target list enclosed in parentheses or in square\n  brackets: The object must be an iterable with the same number of\n  items as there are targets in the target list, and its items are\n  assigned, from left to right, to the corresponding targets.\n\n* If the target is an attribute reference: The primary expression in\n  the reference is evaluated.  It should yield an object with\n  assignable attributes; if this is not the case, ``TypeError`` is\n  raised.  That object is then asked to assign the assigned object to\n  the given attribute; if it cannot perform the assignment, it raises\n  an exception (usually but not necessarily ``AttributeError``).\n\n* If the target is a subscription: The primary expression in the\n  reference is evaluated.  It should yield either a mutable sequence\n  object (such as a list) or a mapping object (such as a dictionary).\n  Next, the subscript expression is evaluated.\n\n  If the primary is a mutable sequence object (such as a list), the\n  subscript must yield an integer.  If it is negative, the sequence\'s\n  length is added to it.  The resulting value must be a nonnegative\n  integer less than the sequence\'s length, and the sequence is asked\n  to assign the assigned object to its item with that index.  If the\n  index is out of range, ``IndexError`` is raised (assignment to a\n  subscripted sequence cannot add new items to a list).\n\n  If the primary is a mapping object (such as a dictionary), the\n  subscript must have a type compatible with the mapping\'s key type,\n  and the mapping is then asked to create a key/datum pair which maps\n  the subscript to the assigned object.  This can either replace an\n  existing key/value pair with the same key value, or insert a new\n  key/value pair (if no key with the same value existed).\n\n  For user-defined objects, the ``__setitem__()`` method is called\n  with appropriate arguments.\n\n* If the target is a slicing: The primary expression in the reference\n  is evaluated.  It should yield a mutable sequence object (such as a\n  list).  The assigned object should be a sequence object of the same\n  type.  Next, the lower and upper bound expressions are evaluated,\n  insofar they are present; defaults are zero and the sequence\'s\n  length.  The bounds should evaluate to integers. If either bound is\n  negative, the sequence\'s length is added to it.  The resulting\n  bounds are clipped to lie between zero and the sequence\'s length,\n  inclusive.  Finally, the sequence object is asked to replace the\n  slice with the items of the assigned sequence.  The length of the\n  slice may be different from the length of the assigned sequence,\n  thus changing the length of the target sequence, if the object\n  allows it.\n\n(In the current implementation, the syntax for targets is taken to be\nthe same as for expressions, and invalid syntax is rejected during the\ncode generation phase, causing less detailed error messages.)\n\nWARNING: Although the definition of assignment implies that overlaps\nbetween the left-hand side and the right-hand side are \'safe\' (for\nexample ``a, b = b, a`` swaps two variables), overlaps *within* the\ncollection of assigned-to variables are not safe!  For instance, the\nfollowing program prints ``[0, 2]``:\n\n   x = [0, 1]\n   i = 0\n   i, x[i] = 1, 2\n   print(x)\n\nSee also:\n\n   **PEP 3132** - Extended Iterable Unpacking\n      The specification for the ``*target`` feature.\n\n\nAugmented assignment statements\n===============================\n\nAugmented assignment is the combination, in a single statement, of a\nbinary operation and an assignment statement:\n\n   augmented_assignment_stmt ::= augtarget augop (expression_list | yield_expression)\n   augtarget                 ::= identifier | attributeref | subscription | slicing\n   augop                     ::= "+=" | "-=" | "*=" | "/=" | "//=" | "%=" | "**="\n             | ">>=" | "<<=" | "&=" | "^=" | "|="\n\n(See section *Primaries* for the syntax definitions for the last three\nsymbols.)\n\nAn augmented assignment evaluates the target (which, unlike normal\nassignment statements, cannot be an unpacking) and the expression\nlist, performs the binary operation specific to the type of assignment\non the two operands, and assigns the result to the original target.\nThe target is only evaluated once.\n\nAn augmented assignment expression like ``x += 1`` can be rewritten as\n``x = x + 1`` to achieve a similar, but not exactly equal effect. In\nthe augmented version, ``x`` is only evaluated once. Also, when\npossible, the actual operation is performed *in-place*, meaning that\nrather than creating a new object and assigning that to the target,\nthe old object is modified instead.\n\nWith the exception of assigning to tuples and multiple targets in a\nsingle statement, the assignment done by augmented assignment\nstatements is handled the same way as normal assignments. Similarly,\nwith the exception of the possible *in-place* behavior, the binary\noperation performed by augmented assignment is the same as the normal\nbinary operations.\n\nFor targets which are attribute references, the initial value is\nretrieved with a ``getattr()`` and the result is assigned with a\n``setattr()``.  Notice that the two methods do not necessarily refer\nto the same variable.  When ``getattr()`` refers to a class variable,\n``setattr()`` still writes to an instance variable. For example:\n\n   class A:\n       x = 3    # class variable\n   a = A()\n   a.x += 1     # writes a.x as 4 leaving A.x as 3\n',

  'atom-identifiers': '\nIdentifiers (Names)\n*******************\n\nAn identifier occurring as an atom is a name.  See section\n*Identifiers and keywords* for lexical definition and section *Naming\nand binding* for documentation of naming and binding.\n\nWhen the name is bound to an object, evaluation of the atom yields\nthat object. When a name is not bound, an attempt to evaluate it\nraises a ``NameError`` exception.\n\n**Private name mangling:** When an identifier that textually occurs in\na class definition begins with two or more underscore characters and\ndoes not end in two or more underscores, it is considered a *private\nname* of that class. Private names are transformed to a longer form\nbefore code is generated for them.  The transformation inserts the\nclass name in front of the name, with leading underscores removed, and\na single underscore inserted in front of the class name.  For example,\nthe identifier ``__spam`` occurring in a class named ``Ham`` will be\ntransformed to ``_Ham__spam``.  This transformation is independent of\nthe syntactical context in which the identifier is used.  If the\ntransformed name is extremely long (longer than 255 characters),\nimplementation defined truncation may happen.  If the class name\nconsists only of underscores, no transformation is done.\n',
  'atom-literals': "\nLiterals\n********\n\nPython supports string and bytes literals and various numeric\nliterals:\n\n   literal ::= stringliteral | bytesliteral\n               | integer | floatnumber | imagnumber\n\nEvaluation of a literal yields an object of the given type (string,\nbytes, integer, floating point number, complex number) with the given\nvalue.  The value may be approximated in the case of floating point\nand imaginary (complex) literals.  See section *Literals* for details.\n\nWith the exception of bytes literals, these all correspond to\nimmutable data types, and hence the object's identity is less\nimportant than its value. Multiple evaluations of literals with the\nsame value (either the same occurrence in the program text or a\ndifferent occurrence) may obtain the same object or a different object\nwith the same value.\n",
- 'attribute-access': '\nCustomizing attribute access\n****************************\n\nThe following methods can be defined to customize the meaning of\nattribute access (use of, assignment to, or deletion of ``x.name``)\nfor class instances.\n\nobject.__getattr__(self, name)\n\n   Called when an attribute lookup has not found the attribute in the\n   usual places (i.e. it is not an instance attribute nor is it found\n   in the class tree for ``self``).  ``name`` is the attribute name.\n   This method should return the (computed) attribute value or raise\n   an ``AttributeError`` exception.\n\n   Note that if the attribute is found through the normal mechanism,\n   ``__getattr__()`` is not called.  (This is an intentional asymmetry\n   between ``__getattr__()`` and ``__setattr__()``.) This is done both\n   for efficiency reasons and because otherwise ``__getattr__()``\n   would have no way to access other attributes of the instance.  Note\n   that at least for instance variables, you can fake total control by\n   not inserting any values in the instance attribute dictionary (but\n   instead inserting them in another object).  See the\n   ``__getattribute__()`` method below for a way to actually get total\n   control over attribute access.\n\nobject.__getattribute__(self, name)\n\n   Called unconditionally to implement attribute accesses for\n   instances of the class. If the class also defines\n   ``__getattr__()``, the latter will not be called unless\n   ``__getattribute__()`` either calls it explicitly or raises an\n   ``AttributeError``. This method should return the (computed)\n   attribute value or raise an ``AttributeError`` exception. In order\n   to avoid infinite recursion in this method, its implementation\n   should always call the base class method with the same name to\n   access any attributes it needs, for example,\n   ``object.__getattribute__(self, name)``.\n\n   Note: This method may still be bypassed when looking up special methods\n     as the result of implicit invocation via language syntax or\n     builtin functions. See *Special method lookup*.\n\nobject.__setattr__(self, name, value)\n\n   Called when an attribute assignment is attempted.  This is called\n   instead of the normal mechanism (i.e. store the value in the\n   instance dictionary). *name* is the attribute name, *value* is the\n   value to be assigned to it.\n\n   If ``__setattr__()`` wants to assign to an instance attribute, it\n   should call the base class method with the same name, for example,\n   ``object.__setattr__(self, name, value)``.\n\nobject.__delattr__(self, name)\n\n   Like ``__setattr__()`` but for attribute deletion instead of\n   assignment.  This should only be implemented if ``del obj.name`` is\n   meaningful for the object.\n\nobject.__dir__(self)\n\n   Called when ``dir()`` is called on the object.  A list must be\n   returned.\n\n\nImplementing Descriptors\n========================\n\nThe following methods only apply when an instance of the class\ncontaining the method (a so-called *descriptor* class) appears in the\nclass dictionary of another class, known as the *owner* class.  In the\nexamples below, "the attribute" refers to the attribute whose name is\nthe key of the property in the owner class\' ``__dict__``.\n\nobject.__get__(self, instance, owner)\n\n   Called to get the attribute of the owner class (class attribute\n   access) or of an instance of that class (instance attribute\n   access). *owner* is always the owner class, while *instance* is the\n   instance that the attribute was accessed through, or ``None`` when\n   the attribute is accessed through the *owner*.  This method should\n   return the (computed) attribute value or raise an\n   ``AttributeError`` exception.\n\nobject.__set__(self, instance, value)\n\n   Called to set the attribute on an instance *instance* of the owner\n   class to a new value, *value*.\n\nobject.__delete__(self, instance)\n\n   Called to delete the attribute on an instance *instance* of the\n   owner class.\n\n\nInvoking Descriptors\n====================\n\nIn general, a descriptor is an object attribute with "binding\nbehavior", one whose attribute access has been overridden by methods\nin the descriptor protocol:  ``__get__()``, ``__set__()``, and\n``__delete__()``. If any of those methods are defined for an object,\nit is said to be a descriptor.\n\nThe default behavior for attribute access is to get, set, or delete\nthe attribute from an object\'s dictionary. For instance, ``a.x`` has a\nlookup chain starting with ``a.__dict__[\'x\']``, then\n``type(a).__dict__[\'x\']``, and continuing through the base classes of\n``type(a)`` excluding metaclasses.\n\nHowever, if the looked-up value is an object defining one of the\ndescriptor methods, then Python may override the default behavior and\ninvoke the descriptor method instead.  Where this occurs in the\nprecedence chain depends on which descriptor methods were defined and\nhow they were called.\n\nThe starting point for descriptor invocation is a binding, ``a.x``.\nHow the arguments are assembled depends on ``a``:\n\nDirect Call\n   The simplest and least common call is when user code directly\n   invokes a descriptor method:    ``x.__get__(a)``.\n\nInstance Binding\n   If binding to an object instance, ``a.x`` is transformed into the\n   call: ``type(a).__dict__[\'x\'].__get__(a, type(a))``.\n\nClass Binding\n   If binding to a class, ``A.x`` is transformed into the call:\n   ``A.__dict__[\'x\'].__get__(None, A)``.\n\nSuper Binding\n   If ``a`` is an instance of ``super``, then the binding ``super(B,\n   obj).m()`` searches ``obj.__class__.__mro__`` for the base class\n   ``A`` immediately preceding ``B`` and then invokes the descriptor\n   with the call: ``A.__dict__[\'m\'].__get__(obj, A)``.\n\nFor instance bindings, the precedence of descriptor invocation depends\non the which descriptor methods are defined.  Normally, data\ndescriptors define both ``__get__()`` and ``__set__()``, while non-\ndata descriptors have just the ``__get__()`` method.  Data descriptors\nalways override a redefinition in an instance dictionary.  In\ncontrast, non-data descriptors can be overridden by instances. [2]\n\nPython methods (including ``staticmethod()`` and ``classmethod()``)\nare implemented as non-data descriptors.  Accordingly, instances can\nredefine and override methods.  This allows individual instances to\nacquire behaviors that differ from other instances of the same class.\n\nThe ``property()`` function is implemented as a data descriptor.\nAccordingly, instances cannot override the behavior of a property.\n\n\n__slots__\n=========\n\nBy default, instances of classes have a dictionary for attribute\nstorage.  This wastes space for objects having very few instance\nvariables.  The space consumption can become acute when creating large\nnumbers of instances.\n\nThe default can be overridden by defining *__slots__* in a class\ndefinition. The *__slots__* declaration takes a sequence of instance\nvariables and reserves just enough space in each instance to hold a\nvalue for each variable.  Space is saved because *__dict__* is not\ncreated for each instance.\n\nobject.__slots__\n\n   This class variable can be assigned a string, iterable, or sequence\n   of strings with variable names used by instances.  If defined in a\n   class, *__slots__* reserves space for the declared variables and\n   prevents the automatic creation of *__dict__* and *__weakref__* for\n   each instance.\n\n\nNotes on using *__slots__*\n--------------------------\n\n* When inheriting from a class without *__slots__*, the *__dict__*\n  attribute of that class will always be accessible, so a *__slots__*\n  definition in the subclass is meaningless.\n\n* Without a *__dict__* variable, instances cannot be assigned new\n  variables not listed in the *__slots__* definition.  Attempts to\n  assign to an unlisted variable name raises ``AttributeError``. If\n  dynamic assignment of new variables is desired, then add\n  ``\'__dict__\'`` to the sequence of strings in the *__slots__*\n  declaration.\n\n* Without a *__weakref__* variable for each instance, classes defining\n  *__slots__* do not support weak references to its instances. If weak\n  reference support is needed, then add ``\'__weakref__\'`` to the\n  sequence of strings in the *__slots__* declaration.\n\n* *__slots__* are implemented at the class level by creating\n  descriptors (*Implementing Descriptors*) for each variable name.  As\n  a result, class attributes cannot be used to set default values for\n  instance variables defined by *__slots__*; otherwise, the class\n  attribute would overwrite the descriptor assignment.\n\n* If a class defines a slot also defined in a base class, the instance\n  variable defined by the base class slot is inaccessible (except by\n  retrieving its descriptor directly from the base class). This\n  renders the meaning of the program undefined.  In the future, a\n  check may be added to prevent this.\n\n* The action of a *__slots__* declaration is limited to the class\n  where it is defined.  As a result, subclasses will have a *__dict__*\n  unless they also define *__slots__*.\n\n* Nonempty *__slots__* does not work for classes derived from\n  "variable-length" built-in types such as ``int``, ``str`` and\n  ``tuple``.\n\n* Any non-string iterable may be assigned to *__slots__*. Mappings may\n  also be used; however, in the future, special meaning may be\n  assigned to the values corresponding to each key.\n\n* *__class__* assignment works only if both classes have the same\n  *__slots__*.\n',
+ 'attribute-access': '\nCustomizing attribute access\n****************************\n\nThe following methods can be defined to customize the meaning of\nattribute access (use of, assignment to, or deletion of ``x.name``)\nfor class instances.\n\nobject.__getattr__(self, name)\n\n   Called when an attribute lookup has not found the attribute in the\n   usual places (i.e. it is not an instance attribute nor is it found\n   in the class tree for ``self``).  ``name`` is the attribute name.\n   This method should return the (computed) attribute value or raise\n   an ``AttributeError`` exception.\n\n   Note that if the attribute is found through the normal mechanism,\n   ``__getattr__()`` is not called.  (This is an intentional asymmetry\n   between ``__getattr__()`` and ``__setattr__()``.) This is done both\n   for efficiency reasons and because otherwise ``__getattr__()``\n   would have no way to access other attributes of the instance.  Note\n   that at least for instance variables, you can fake total control by\n   not inserting any values in the instance attribute dictionary (but\n   instead inserting them in another object).  See the\n   ``__getattribute__()`` method below for a way to actually get total\n   control over attribute access.\n\nobject.__getattribute__(self, name)\n\n   Called unconditionally to implement attribute accesses for\n   instances of the class. If the class also defines\n   ``__getattr__()``, the latter will not be called unless\n   ``__getattribute__()`` either calls it explicitly or raises an\n   ``AttributeError``. This method should return the (computed)\n   attribute value or raise an ``AttributeError`` exception. In order\n   to avoid infinite recursion in this method, its implementation\n   should always call the base class method with the same name to\n   access any attributes it needs, for example,\n   ``object.__getattribute__(self, name)``.\n\n   Note: This method may still be bypassed when looking up special methods\n     as the result of implicit invocation via language syntax or\n     built-in functions. See *Special method lookup*.\n\nobject.__setattr__(self, name, value)\n\n   Called when an attribute assignment is attempted.  This is called\n   instead of the normal mechanism (i.e. store the value in the\n   instance dictionary). *name* is the attribute name, *value* is the\n   value to be assigned to it.\n\n   If ``__setattr__()`` wants to assign to an instance attribute, it\n   should call the base class method with the same name, for example,\n   ``object.__setattr__(self, name, value)``.\n\nobject.__delattr__(self, name)\n\n   Like ``__setattr__()`` but for attribute deletion instead of\n   assignment.  This should only be implemented if ``del obj.name`` is\n   meaningful for the object.\n\nobject.__dir__(self)\n\n   Called when ``dir()`` is called on the object.  A list must be\n   returned.\n\n\nImplementing Descriptors\n========================\n\nThe following methods only apply when an instance of the class\ncontaining the method (a so-called *descriptor* class) appears in the\nclass dictionary of another class, known as the *owner* class.  In the\nexamples below, "the attribute" refers to the attribute whose name is\nthe key of the property in the owner class\' ``__dict__``.\n\nobject.__get__(self, instance, owner)\n\n   Called to get the attribute of the owner class (class attribute\n   access) or of an instance of that class (instance attribute\n   access). *owner* is always the owner class, while *instance* is the\n   instance that the attribute was accessed through, or ``None`` when\n   the attribute is accessed through the *owner*.  This method should\n   return the (computed) attribute value or raise an\n   ``AttributeError`` exception.\n\nobject.__set__(self, instance, value)\n\n   Called to set the attribute on an instance *instance* of the owner\n   class to a new value, *value*.\n\nobject.__delete__(self, instance)\n\n   Called to delete the attribute on an instance *instance* of the\n   owner class.\n\n\nInvoking Descriptors\n====================\n\nIn general, a descriptor is an object attribute with "binding\nbehavior", one whose attribute access has been overridden by methods\nin the descriptor protocol:  ``__get__()``, ``__set__()``, and\n``__delete__()``. If any of those methods are defined for an object,\nit is said to be a descriptor.\n\nThe default behavior for attribute access is to get, set, or delete\nthe attribute from an object\'s dictionary. For instance, ``a.x`` has a\nlookup chain starting with ``a.__dict__[\'x\']``, then\n``type(a).__dict__[\'x\']``, and continuing through the base classes of\n``type(a)`` excluding metaclasses.\n\nHowever, if the looked-up value is an object defining one of the\ndescriptor methods, then Python may override the default behavior and\ninvoke the descriptor method instead.  Where this occurs in the\nprecedence chain depends on which descriptor methods were defined and\nhow they were called.\n\nThe starting point for descriptor invocation is a binding, ``a.x``.\nHow the arguments are assembled depends on ``a``:\n\nDirect Call\n   The simplest and least common call is when user code directly\n   invokes a descriptor method:    ``x.__get__(a)``.\n\nInstance Binding\n   If binding to an object instance, ``a.x`` is transformed into the\n   call: ``type(a).__dict__[\'x\'].__get__(a, type(a))``.\n\nClass Binding\n   If binding to a class, ``A.x`` is transformed into the call:\n   ``A.__dict__[\'x\'].__get__(None, A)``.\n\nSuper Binding\n   If ``a`` is an instance of ``super``, then the binding ``super(B,\n   obj).m()`` searches ``obj.__class__.__mro__`` for the base class\n   ``A`` immediately preceding ``B`` and then invokes the descriptor\n   with the call: ``A.__dict__[\'m\'].__get__(obj, A)``.\n\nFor instance bindings, the precedence of descriptor invocation depends\non the which descriptor methods are defined.  A descriptor can define\nany combination of ``__get__()``, ``__set__()`` and ``__delete__()``.\nIf it does not define ``__get__()``, then accessing the attribute will\nreturn the descriptor object itself unless there is a value in the\nobject\'s instance dictionary.  If the descriptor defines ``__set__()``\nand/or ``__delete__()``, it is a data descriptor; if it defines\nneither, it is a non-data descriptor.  Normally, data descriptors\ndefine both ``__get__()`` and ``__set__()``, while non-data\ndescriptors have just the ``__get__()`` method.  Data descriptors with\n``__set__()`` and ``__get__()`` defined always override a redefinition\nin an instance dictionary.  In contrast, non-data descriptors can be\noverridden by instances.\n\nPython methods (including ``staticmethod()`` and ``classmethod()``)\nare implemented as non-data descriptors.  Accordingly, instances can\nredefine and override methods.  This allows individual instances to\nacquire behaviors that differ from other instances of the same class.\n\nThe ``property()`` function is implemented as a data descriptor.\nAccordingly, instances cannot override the behavior of a property.\n\n\n__slots__\n=========\n\nBy default, instances of classes have a dictionary for attribute\nstorage.  This wastes space for objects having very few instance\nvariables.  The space consumption can become acute when creating large\nnumbers of instances.\n\nThe default can be overridden by defining *__slots__* in a class\ndefinition. The *__slots__* declaration takes a sequence of instance\nvariables and reserves just enough space in each instance to hold a\nvalue for each variable.  Space is saved because *__dict__* is not\ncreated for each instance.\n\nobject.__slots__\n\n   This class variable can be assigned a string, iterable, or sequence\n   of strings with variable names used by instances.  If defined in a\n   class, *__slots__* reserves space for the declared variables and\n   prevents the automatic creation of *__dict__* and *__weakref__* for\n   each instance.\n\n\nNotes on using *__slots__*\n--------------------------\n\n* When inheriting from a class without *__slots__*, the *__dict__*\n  attribute of that class will always be accessible, so a *__slots__*\n  definition in the subclass is meaningless.\n\n* Without a *__dict__* variable, instances cannot be assigned new\n  variables not listed in the *__slots__* definition.  Attempts to\n  assign to an unlisted variable name raises ``AttributeError``. If\n  dynamic assignment of new variables is desired, then add\n  ``\'__dict__\'`` to the sequence of strings in the *__slots__*\n  declaration.\n\n* Without a *__weakref__* variable for each instance, classes defining\n  *__slots__* do not support weak references to its instances. If weak\n  reference support is needed, then add ``\'__weakref__\'`` to the\n  sequence of strings in the *__slots__* declaration.\n\n* *__slots__* are implemented at the class level by creating\n  descriptors (*Implementing Descriptors*) for each variable name.  As\n  a result, class attributes cannot be used to set default values for\n  instance variables defined by *__slots__*; otherwise, the class\n  attribute would overwrite the descriptor assignment.\n\n* The action of a *__slots__* declaration is limited to the class\n  where it is defined.  As a result, subclasses will have a *__dict__*\n  unless they also define *__slots__* (which must only contain names\n  of any *additional* slots).\n\n* If a class defines a slot also defined in a base class, the instance\n  variable defined by the base class slot is inaccessible (except by\n  retrieving its descriptor directly from the base class). This\n  renders the meaning of the program undefined.  In the future, a\n  check may be added to prevent this.\n\n* Nonempty *__slots__* does not work for classes derived from\n  "variable-length" built-in types such as ``int``, ``str`` and\n  ``tuple``.\n\n* Any non-string iterable may be assigned to *__slots__*. Mappings may\n  also be used; however, in the future, special meaning may be\n  assigned to the values corresponding to each key.\n\n* *__class__* assignment works only if both classes have the same\n  *__slots__*.\n',
  'attribute-references': '\nAttribute references\n********************\n\nAn attribute reference is a primary followed by a period and a name:\n\n   attributeref ::= primary "." identifier\n\nThe primary must evaluate to an object of a type that supports\nattribute references, which most objects do.  This object is then\nasked to produce the attribute whose name is the identifier (which can\nbe customized by overriding the ``__getattr__()`` method).  If this\nattribute is not available, the exception ``AttributeError`` is\nraised.  Otherwise, the type and value of the object produced is\ndetermined by the object.  Multiple evaluations of the same attribute\nreference may yield different objects.\n',

Notice that the two methods do not necessarily refer\nto the same variable.  When ``getattr()`` refers to a class variable,\n``setattr()`` still writes to an instance variable.

  'binary': '\nBinary arithmetic operations\n****************************\n\nThe binary arithmetic operations have the conventional priority\nlevels.  Note that some of these operations also apply to certain non-\nnumeric types.  Apart from the power operator, there are only two\nlevels, one for multiplicative operators and one for additive\noperators:\n\n   m_expr ::= u_expr | m_expr "*" u_expr | m_expr "//" u_expr | m_expr "/" u_expr\n              | m_expr "%" u_expr\n   a_expr ::= m_expr | a_expr "+" m_expr | a_expr "-" m_expr\n\nThe ``*`` (multiplication) operator yields the product of its\narguments.  The arguments must either both be numbers, or one argument\nmust be an integer and the other must be a sequence. In the former\ncase, the numbers are converted to a common type and then multiplied\ntogether.  In the latter case, sequence repetition is performed; a\nnegative repetition factor yields an empty sequence.\n\nThe ``/`` (division) and ``//`` (floor division) operators yield the\nquotient of their arguments.  The numeric arguments are first\nconverted to a common type. Integer division yields a float, while\nfloor division of integers results in an integer; the result is that\nof mathematical division with the \'floor\' function applied to the\nresult.  Division by zero raises the ``ZeroDivisionError`` exception.\n\nThe ``%`` (modulo) operator yields the remainder from the division of\nthe first argument by the second.  The numeric arguments are first\nconverted to a common type.  A zero right argument raises the\n``ZeroDivisionError`` exception.  The arguments may be floating point\nnumbers, e.g., ``3.14%0.7`` equals ``0.34`` (since ``3.14`` equals\n``4*0.7 + 0.34``.)  The modulo operator always yields a result with\nthe same sign as its second operand (or zero); the absolute value of\nthe result is strictly smaller than the absolute value of the second\noperand [1].\n\nThe floor division and modulo operators are connected by the following\nidentity: ``x == (x//y)*y + (x%y)``.  Floor division and modulo are\nalso connected with the built-in function ``divmod()``: ``divmod(x, y)\n== (x//y, x%y)``. [2].\n\nIn addition to performing the modulo operation on numbers, the ``%``\noperator is also overloaded by string objects to perform old-style\nstring formatting (also known as interpolation).  The syntax for\nstring formatting is described in the Python Library Reference,\nsection *Old String Formatting Operations*.\n\nThe floor division operator, the modulo operator, and the ``divmod()``\nfunction are not defined for complex numbers.  Instead, convert to a\nfloating point number using the ``abs()`` function if appropriate.\n\nThe ``+`` (addition) operator yields the sum of its arguments.  The\narguments must either both be numbers or both sequences of the same\ntype.  In the former case, the numbers are converted to a common type\nand then added together.  In the latter case, the sequences are\nconcatenated.\n\nThe ``-`` (subtraction) operator yields the difference of its\narguments.  The numeric arguments are first converted to a common\ntype.\n',

  'bltin-code-objects': '\nCode Objects\n************\n\nCode objects are used by the implementation to represent "pseudo-\ncompiled" executable Python code such as a function body. They differ\nfrom function objects because they don\'t contain a reference to their\nglobal execution environment.  Code objects are returned by the built-\nin ``compile()`` function and can be extracted from function objects\nthrough their ``__code__`` attribute. See also the ``code`` module.\n\nA code object can be executed or evaluated by passing it (instead of a\nsource string) to the ``exec()`` or ``eval()``  built-in functions.\n\nSee *The standard type hierarchy* for more information.\n',
  'bltin-ellipsis-object': '\nThe Ellipsis Object\n*******************\n\nThis object is commonly used by slicing (see *Slicings*).  It supports\nno special operations.  There is exactly one ellipsis object, named\n``Ellipsis`` (a built-in name).\n\nIt is written as ``Ellipsis`` or ``...``.\n',
- 'bltin-file-objects': '\nFile Objects\n************\n\nFile objects are implemented using C\'s ``stdio`` package and can be\ncreated with the built-in ``open()`` function.  File objects are also\nreturned by some other built-in functions and methods, such as\n``os.popen()`` and ``os.fdopen()`` and the ``makefile()`` method of\nsocket objects. Temporary files can be created using the ``tempfile``\nmodule, and high-level file operations such as copying, moving, and\ndeleting files and directories can be achieved with the ``shutil``\nmodule.\n\nWhen a file operation fails for an I/O-related reason, the exception\n``IOError`` is raised.  This includes situations where the operation\nis not defined for some reason, like ``seek()`` on a tty device or\nwriting a file opened for reading.\n\nFiles have the following methods:\n\nfile.close()\n\n   Close the file.  A closed file cannot be read or written any more.\n   Any operation which requires that the file be open will raise a\n   ``ValueError`` after the file has been closed.  Calling ``close()``\n   more than once is allowed.\n\n   You can avoid having to call this method explicitly if you use the\n   ``with`` statement.  For example, the following code will\n   automatically close *f* when the ``with`` block is exited:\n\n      from __future__ import with_statement # This isn\'t required in Python 2.6\n\n      with open("hello.txt") as f:\n          for line in f:\n              print(line)\n\n   In older versions of Python, you would have needed to do this to\n   get the same effect:\n\n      f = open("hello.txt")\n      try:\n          for line in f:\n              print(line)\n      finally:\n          f.close()\n\n   Note: Not all "file-like" types in Python support use as a context\n     manager for the ``with`` statement.  If your code is intended to\n     work with any file-like object, you can use the function\n     ``contextlib.closing()`` instead of using the object directly.\n\nfile.flush()\n\n   Flush the internal buffer, like ``stdio``\'s ``fflush()``.  This may\n   be a no-op on some file-like objects.\n\n   Note: ``flush()`` does not necessarily write the file\'s data to disk.\n     Use ``flush()`` followed by ``os.fsync()`` to ensure this\n     behavior.\n\nfile.fileno()\n\n   Return the integer "file descriptor" that is used by the underlying\n   implementation to request I/O operations from the operating system.\n   This can be useful for other, lower level interfaces that use file\n   descriptors, such as the ``fcntl`` module or ``os.read()`` and\n   friends.\n\n   Note: File-like objects which do not have a real file descriptor should\n     *not* provide this method!\n\nfile.isatty()\n\n   Return ``True`` if the file is connected to a tty(-like) device,\n   else ``False``.\n\n   Note: If a file-like object is not associated with a real file, this\n     method should *not* be implemented.\n\nfile.__next__()\n\n   A file object is its own iterator, for example ``iter(f)`` returns\n   *f* (unless *f* is closed).  When a file is used as an iterator,\n   typically in a ``for`` loop (for example, ``for line in f:\n   print(line)``), the ``__next__()`` method is called repeatedly.\n   This method returns the next input line, or raises\n   ``StopIteration`` when EOF is hit when the file is open for reading\n   (behavior is undefined when the file is open for writing).  In\n   order to make a ``for`` loop the most efficient way of looping over\n   the lines of a file (a very common operation), the ``__next__()``\n   method uses a hidden read-ahead buffer.  As a consequence of using\n   a read-ahead buffer, combining ``__next__()`` with other file\n   methods (like ``readline()``) does not work right.  However, using\n   ``seek()`` to reposition the file to an absolute position will\n   flush the read-ahead buffer.\n\nfile.read([size])\n\n   Read at most *size* bytes from the file (less if the read hits EOF\n   before obtaining *size* bytes).  If the *size* argument is negative\n   or omitted, read all data until EOF is reached.  The bytes are\n   returned as a string object.  An empty string is returned when EOF\n   is encountered immediately.  (For certain files, like ttys, it\n   makes sense to continue reading after an EOF is hit.)  Note that\n   this method may call the underlying C function ``fread()`` more\n   than once in an effort to acquire as close to *size* bytes as\n   possible. Also note that when in non-blocking mode, less data than\n   was requested may be returned, even if no *size* parameter was\n   given.\n\nfile.readline([size])\n\n   Read one entire line from the file.  A trailing newline character\n   is kept in the string (but may be absent when a file ends with an\n   incomplete line). [5]  If the *size* argument is present and non-\n   negative, it is a maximum byte count (including the trailing\n   newline) and an incomplete line may be returned. An empty string is\n   returned *only* when EOF is encountered immediately.\n\n   Note: Unlike ``stdio``\'s ``fgets()``, the returned string contains null\n     characters (``\'\\0\'``) if they occurred in the input.\n\nfile.readlines([sizehint])\n\n   Read until EOF using ``readline()`` and return a list containing\n   the lines thus read.  If the optional *sizehint* argument is\n   present, instead of reading up to EOF, whole lines totalling\n   approximately *sizehint* bytes (possibly after rounding up to an\n   internal buffer size) are read.  Objects implementing a file-like\n   interface may choose to ignore *sizehint* if it cannot be\n   implemented, or cannot be implemented efficiently.\n\nfile.seek(offset[, whence])\n\n   Set the file\'s current position, like ``stdio``\'s ``fseek()``. The\n   *whence* argument is optional and defaults to  ``os.SEEK_SET`` or\n   ``0`` (absolute file positioning); other values are ``os.SEEK_CUR``\n   or ``1`` (seek relative to the current position) and\n   ``os.SEEK_END`` or ``2``  (seek relative to the file\'s end).  There\n   is no return value.\n\n   For example, ``f.seek(2, os.SEEK_CUR)`` advances the position by\n   two and ``f.seek(-3, os.SEEK_END)`` sets the position to the third\n   to last.\n\n   Note that if the file is opened for appending (mode ``\'a\'`` or\n   ``\'a+\'``), any ``seek()`` operations will be undone at the next\n   write.  If the file is only opened for writing in append mode (mode\n   ``\'a\'``), this method is essentially a no-op, but it remains useful\n   for files opened in append mode with reading enabled (mode\n   ``\'a+\'``).  If the file is opened in text mode (without ``\'b\'``),\n   only offsets returned by ``tell()`` are legal.  Use of other\n   offsets causes undefined behavior.\n\n   Note that not all file objects are seekable.\n\nfile.tell()\n\n   Return the file\'s current position, like ``stdio``\'s ``ftell()``.\n\n   Note: On Windows, ``tell()`` can return illegal values (after an\n     ``fgets()``) when reading files with Unix-style line-endings. Use\n     binary mode (``\'rb\'``) to circumvent this problem.\n\nfile.truncate([size])\n\n   Truncate the file\'s size.  If the optional *size* argument is\n   present, the file is truncated to (at most) that size.  The size\n   defaults to the current position. The current file position is not\n   changed.  Note that if a specified size exceeds the file\'s current\n   size, the result is platform-dependent:  possibilities include that\n   the file may remain unchanged, increase to the specified size as if\n   zero-filled, or increase to the specified size with undefined new\n   content. Availability:  Windows, many Unix variants.\n\nfile.write(str)\n\n   Write a string to the file.  Due to buffering, the string may not\n   actually show up in the file until the ``flush()`` or ``close()``\n   method is called.\n\n   The meaning of the return value is not defined for every file-like\n   object. Some (mostly low-level) file-like objects may return the\n   number of bytes actually written, others return ``None``.\n\nfile.writelines(sequence)\n\n   Write a sequence of strings to the file.  The sequence can be any\n   iterable object producing strings, typically a list of strings.\n   There is no return value. (The name is intended to match\n   ``readlines()``; ``writelines()`` does not add line separators.)\n\nFiles support the iterator protocol.  Each iteration returns the same\nresult as ``file.readline()``, and iteration ends when the\n``readline()`` method returns an empty string.\n\nFile objects also offer a number of other interesting attributes.\nThese are not required for file-like objects, but should be\nimplemented if they make sense for the particular object.\n\nfile.closed\n\n   bool indicating the current state of the file object.  This is a\n   read-only attribute; the ``close()`` method changes the value. It\n   may not be available on all file-like objects.\n\nfile.encoding\n\n   The encoding that this file uses. When strings are written to a\n   file, they will be converted to byte strings using this encoding.\n   In addition, when the file is connected to a terminal, the\n   attribute gives the encoding that the terminal is likely to use\n   (that  information might be incorrect if the user has misconfigured\n   the  terminal). The attribute is read-only and may not be present\n   on all file-like objects. It may also be ``None``, in which case\n   the file uses the system default encoding for converting strings.\n\nfile.errors\n\n   The Unicode error handler used along with the encoding.\n\nfile.mode\n\n   The I/O mode for the file.  If the file was created using the\n   ``open()`` built-in function, this will be the value of the *mode*\n   parameter.  This is a read-only attribute and may not be present on\n   all file-like objects.\n\nfile.name\n\n   If the file object was created using ``open()``, the name of the\n   file. Otherwise, some string that indicates the source of the file\n   object, of the form ``<...>``.  This is a read-only attribute and\n   may not be present on all file-like objects.\n\nfile.newlines\n\n   If Python was built with the *--with-universal-newlines* option to\n   **configure** (the default) this read-only attribute exists, and\n   for files opened in universal newline read mode it keeps track of\n   the types of newlines encountered while reading the file. The\n   values it can take are ``\'\\r\'``, ``\'\\n\'``, ``\'\\r\\n\'``, ``None``\n   (unknown, no newlines read yet) or a tuple containing all the\n   newline types seen, to indicate that multiple newline conventions\n   were encountered. For files not opened in universal newline read\n   mode the value of this attribute will be ``None``.\n',

All argument expressions are\nevaluated before the call is attempted.  Please refer to section\n*Function definitions* for the syntax of formal parameter lists.\n\nIf keyword arguments are present, they are first converted to\npositional arguments, as follows.  First, a list of unfilled slots is\ncreated for the formal parameters.  If there are N positional\narguments, they are placed in the first N slots.  Next, for each\nkeyword argument, the identifier is used to determine the\ncorresponding slot (if the identifier is the same as the first formal\nparameter name, the first slot is used, and so on).  If the slot is\nalready filled, a ``TypeError`` exception is raised. Otherwise, the\nvalue of the argument is placed in the slot, filling it (even if the\nexpression is ``None``, it fills the slot).  When all arguments have\nbeen processed, the slots that are still unfilled are filled with the\ncorresponding default value from the function definition.  (Default\nvalues are calculated, once, when the function is defined; thus, a\nmutable object such as a list or dictionary used as default value will\nbe shared by all calls that don\'t specify an argument value for the\ncorresponding slot; this should usually be avoided.)  If there are any\nunfilled slots for which no default value is specified, a\n``TypeError`` exception is raised.  Otherwise, the list of filled\nslots is used as the argument list for the call.\n\nNote: An implementation may provide builtin functions whose positional\n  parameters do not have names, even if they are \'named\' for the\n  purpose of documentation, and which therefore cannot be supplied by\n  keyword.  In CPython, this is the case for functions implemented in\n  C that use ``PyArg_ParseTuple()`` to parse their arguments.\n\nIf there are more positional arguments than there are formal parameter\nslots, a ``TypeError`` exception is raised, unless a formal parameter\nusing the syntax ``*identifier`` is present; in this case, that formal\nparameter receives a tuple containing the excess positional arguments\n(or an empty tuple if there were no excess positional arguments).\n\nIf any keyword argument does not correspond to a formal parameter\nname, a ``TypeError`` exception is raised, unless a formal parameter\nusing the syntax ``**identifier`` is present; in this case, that\nformal parameter receives a dictionary containing the excess keyword\narguments (using the keywords as keys and the argument values as\ncorresponding values), or a (new) empty dictionary if there were no\nexcess keyword arguments.\n\nIf the syntax ``*expression`` appears in the function call,\n``expression`` must evaluate to a sequence.  Elements from this\nsequence are treated as if they were additional positional arguments;\nif there are positional arguments *x1*,..., *xN*, and ``expression``\nevaluates to a sequence *y1*, ..., *yM*, this is equivalent to a call\nwith M+N positional arguments *x1*, ..., *xN*, *y1*, ..., *yM*.\n\nA consequence of this is that although the ``*expression`` syntax may\nappear *after* some keyword arguments, it is processed *before* the\nkeyword arguments (and the ``**expression`` argument, if any -- see\nbelow).  So:\n\n   >>> def f(a, b):\n   ...  print(a, b)\n   ...\n   >>> f(b=1, *(2,))\n   2 1\n   >>> f(a=1, *(2,))\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in ?\n   TypeError: f() got multiple values for keyword argument \'a\'\n   >>> f(1, *(2,))\n   1 2\n\nIt is unusual for both keyword arguments and the ``*expression``\nsyntax to be used in the same call, so in practice this confusion does\nnot arise.\n\nIf the syntax ``**expression`` appears in the function call,\n``expression`` must evaluate to a mapping, the contents of which are\ntreated as additional keyword arguments.  In the case of a keyword\nappearing in both ``expression`` and as an explicit keyword argument,\na ``TypeError`` exception is raised.\n\nFormal parameters using the syntax ``*identifier`` or ``**identifier``\ncannot be used as positional argument slots or as keyword argument\nnames.\n\nA call always returns some value, possibly ``None``, unless it raises\nan exception.  How this value is computed depends on the type of the\ncallable object.\n\nIf it is---\n\na user-defined function:\n   The code block for the function is executed, passing it the\n   argument list.  The first thing the code block will do is bind the\n   formal parameters to the arguments; this is described in section\n   *Function definitions*.  When the code block executes a ``return``\n   statement, this specifies the return value of the function call.\n\na built-in function or method:\n   The result is up to the interpreter; see *Built-in Functions* for\n   the descriptions of built-in functions and methods.\n\na class object:\n   A new instance of that class is returned.\n\na class instance method:\n   The corresponding user-defined function is called, with an argument\n   list that is one longer than the argument list of the call: the\n   instance becomes the first argument.\n\na class instance:\n   The class must define a ``__call__()`` method; the effect is then\n   the same as if that method was called.\n',

It first evaluates the\ninheritance list, if present.  Each item in the inheritance list\nshould evaluate to a class object or class type which allows\nsubclassing.  The class\'s suite is then executed in a new execution\nframe (see section *Naming and binding*), using a newly created local\nnamespace and the original global namespace. (Usually, the suite\ncontains only function definitions.)  When the class\'s suite finishes\nexecution, its execution frame is discarded but its local namespace is\nsaved. [4] A class object is then created using the inheritance list\nfor the base classes and the saved local namespace for the attribute\ndictionary.  The class name is bound to this class object in the\noriginal local namespace.\n\nClasses can also be decorated; as with functions,\n\n   @f1(arg)\n   @f2\n   class Foo: pass\n\nis equivalent to\n\n   class Foo: pass\n   Foo = f1(arg)(f2(Foo))\n\n**Programmer\'s note:** Variables defined in the class definition are\nclass variables; they are shared by instances. Instance variables can\nbe set in a method with ``self.name = value``.  Both class and\ninstance variables are accessible through the notation\n"``self.name``", and an instance variable hides a class variable with\nthe same name when accessed in this way.  Class variables can be used\nas defaults for instance variables, but using mutable values there can\nlead to unexpected results.  Descriptors can be used to create\ninstance variables with different implementation details.\n\nSee also:\n\n   **PEP 3129** - Class Decorators\n\nClass definitions, like function definitions, may be wrapped by one or\nmore *decorator* expressions.

- 'comparisons': '\nComparisons\n***********\n\nUnlike C, all comparison operations in Python have the same priority,\nwhich is lower than that of any arithmetic, shifting or bitwise\noperation.  Also unlike C, expressions like ``a < b < c`` have the\ninterpretation that is conventional in mathematics:\n\n   comparison    ::= or_expr ( comp_operator or_expr )*\n   comp_operator ::= "<" | ">" | "==" | ">=" | "<=" | "!="\n                     | "is" ["not"] | ["not"] "in"\n\nComparisons yield boolean values: ``True`` or ``False``.\n\nComparisons can be chained arbitrarily, e.g., ``x < y <= z`` is\nequivalent to ``x < y and y <= z``, except that ``y`` is evaluated\nonly once (but in both cases ``z`` is not evaluated at all when ``x <\ny`` is found to be false).\n\nFormally, if *a*, *b*, *c*, ..., *y*, *z* are expressions and *op1*,\n*op2*, ..., *opN* are comparison operators, then ``a op1 b op2 c ... y\nopN z`` is equivalent to ``a op1 b and b op2 c and ... y opN z``,\nexcept that each expression is evaluated at most once.\n\nNote that ``a op1 b op2 c`` doesn\'t imply any kind of comparison\nbetween *a* and *c*, so that, e.g., ``x < y > z`` is perfectly legal\n(though perhaps not pretty).\n\nThe operators ``<``, ``>``, ``==``, ``>=``, ``<=``, and ``!=`` compare\nthe values of two objects.  The objects need not have the same type.\nIf both are numbers, they are converted to a common type.  Otherwise,\nthe ``==`` and ``!=`` operators *always* consider objects of different\ntypes to be unequal, while the ``<``, ``>``, ``>=`` and ``<=``\noperators raise a ``TypeError`` when comparing objects of different\ntypes that do not implement these operators for the given pair of\ntypes.  You can control comparison behavior of objects of non-builtin\ntypes by defining rich comparison methods like ``__gt__()``, described\nin section *Basic customization*.\n\nComparison of objects of the same type depends on the type:\n\n* Numbers are compared arithmetically.\n\n* The values ``float(\'NaN\')`` and ``Decimal(\'NaN\')`` are special. The\n  are identical to themselves, ``x is x`` but are not equal to\n  themselves, ``x != x``.  Additionally, comparing any value to a\n  not-a-number value will return ``False``.  For example, both ``3 <\n  float(\'NaN\')`` and ``float(\'NaN\') < 3`` will return ``False``.\n\n* Bytes objects are compared lexicographically using the numeric\n  values of their elements.\n\n* Strings are compared lexicographically using the numeric equivalents\n  (the result of the built-in function ``ord()``) of their characters.\n  [3] String and bytes object can\'t be compared!\n\n* Tuples and lists are compared lexicographically using comparison of\n  corresponding elements.  This means that to compare equal, each\n  element must compare equal and the two sequences must be of the same\n  type and have the same length.\n\n  If not equal, the sequences are ordered the same as their first\n  differing elements.  For example, ``[1,2,x] <= [1,2,y]`` has the\n  same value as ``x <= y``.  If the corresponding element does not\n  exist, the shorter sequence is ordered first (for example, ``[1,2] <\n  [1,2,3]``).\n\n* Mappings (dictionaries) compare equal if and only if their sorted\n  ``(key, value)`` lists compare equal. [4] Outcomes other than\n  equality are resolved consistently, but are not otherwise defined.\n  [5]\n\n* Sets and frozensets define comparison operators to mean subset and\n  superset tests.  Those relations do not define total orderings (the\n  two sets ``{1,2}`` and {2,3} are not equal, nor subsets of one\n  another, nor supersets of one another).  Accordingly, sets are not\n  appropriate arguments for functions which depend on total ordering.\n  For example, ``min()``, ``max()``, and ``sorted()`` produce\n  undefined results given a list of sets as inputs.\n\n* Most other objects of builtin types compare unequal unless they are\n  the same object; the choice whether one object is considered smaller\n  or larger than another one is made arbitrarily but consistently\n  within one execution of a program.\n\nComparison of objects of the differing types depends on whether either\nof the types provide explicit support for the comparison.  Most\nnumeric types can be compared with one another, but comparisons of\n``float`` and ``Decimal`` are not supported to avoid the inevitable\nconfusion arising from representation issues such as ``float(\'1.1\')``\nbeing inexactly represented and therefore not exactly equal to\n``Decimal(\'1.1\')`` which is.  When cross-type comparison is not\nsupported, the comparison method returns ``NotImplemented``.  This can\ncreate the illusion of non-transitivity between supported cross-type\ncomparisons and unsupported comparisons.  For example, ``Decimal(2) ==\n2`` and *2 == float(2)`* but ``Decimal(2) != float(2)``.\n\nThe operators ``in`` and ``not in`` test for membership.  ``x in s``\nevaluates to true if *x* is a member of *s*, and false otherwise.  ``x\nnot in s`` returns the negation of ``x in s``.  All built-in sequences\nand set types support this as well as dictionary, for which ``in``\ntests whether a the dictionary has a given key. For container types\nsuch as list, tuple, set, frozenset, dict, or collections.deque, the\nexpression ``x in y`` is equivalent to ``any(x is e or x == e for val\ne in y)``.\n\nFor the string and bytes types, ``x in y`` is true if and only if *x*\nis a substring of *y*.  An equivalent test is ``y.find(x) != -1``.\nEmpty strings are always considered to be a substring of any other\nstring, so ``"" in "abc"`` will return ``True``.\n\nFor user-defined classes which define the ``__contains__()`` method,\n``x in y`` is true if and only if ``y.__contains__(x)`` is true.\n\nFor user-defined classes which do not define ``__contains__()`` and do\ndefine ``__getitem__()``, ``x in y`` is true if and only if there is a\nnon-negative integer index *i* such that ``x == y[i]``, and all lower\ninteger indices do not raise ``IndexError`` exception.  (If any other\nexception is raised, it is as if ``in`` raised that exception).\n\nThe operator ``not in`` is defined to have the inverse true value of\n``in``.\n\nThe operators ``is`` and ``is not`` test for object identity: ``x is\ny`` is true if and only if *x* and *y* are the same object.  ``x is\nnot y`` yields the inverse truth value.

- 'compound': '\nCompound statements\n*******************\n\nCompound statements contain (groups of) other statements; they affect\nor control the execution of those other statements in some way.  In\ngeneral, compound statements span multiple lines, although in simple\nincarnations a whole compound statement may be contained in one line.\n\nThe ``if``, ``while`` and ``for`` statements implement traditional\ncontrol flow constructs.  ``try`` specifies exception handlers and/or\ncleanup code for a group of statements, while the ``with`` statement\nallows the execution of initialization and finalization code around a\nblock of code.  Function and class definitions are also syntactically\ncompound statements.\n\nCompound statements consist of one or more \'clauses.\'  A clause\nconsists of a header and a \'suite.\'  The clause headers of a\nparticular compound statement are all at the same indentation level.\nEach clause header begins with a uniquely identifying keyword and ends\nwith a colon.  A suite is a group of statements controlled by a\nclause.  A suite can be one or more semicolon-separated simple\nstatements on the same line as the header, following the header\'s\ncolon, or it can be one or more indented statements on subsequent\nlines.  Only the latter form of suite can contain nested compound\nstatements; the following is illegal, mostly because it wouldn\'t be\nclear to which ``if`` clause a following ``else`` clause would belong:\n\n   if test1: if test2: print(x)\n\nAlso note that the semicolon binds tighter than the colon in this\ncontext, so that in the following example, either all or none of the\n``print()`` calls are executed:\n\n   if x < y < z: print(x); print(y); print(z)\n\nSummarizing:\n\n   compound_stmt ::= if_stmt\n                     | while_stmt\n                     | for_stmt\n                     | try_stmt\n                     | with_stmt\n                     | funcdef\n                     | classdef\n   suite         ::= stmt_list NEWLINE | NEWLINE INDENT statement+ DEDENT\n   statement     ::= stmt_list NEWLINE | compound_stmt\n   stmt_list     ::= simple_stmt (";" simple_stmt)* [";"]\n\nNote that statements always end in a ``NEWLINE`` possibly followed by\na ``DEDENT``.  Also note that optional continuation clauses always\nbegin with a keyword that cannot start a statement, thus there are no\nambiguities (the \'dangling ``else``\' problem is solved in Python by\nrequiring nested ``if`` statements to be indented).\n\nThe formatting of the grammar rules in the following sections places\neach clause on a separate line for clarity.\n\n\nThe ``if`` statement\n====================\n\nThe ``if`` statement is used for conditional execution:\n\n   if_stmt ::= "if" expression ":" suite\n               ( "elif" expression ":" suite )*\n               ["else" ":" suite]\n\nIt selects exactly one of the suites by evaluating the expressions one\nby one until one is found to be true (see section *Boolean operations*\nfor the definition of true and false); then that suite is executed\n(and no other part of the ``if`` statement is executed or evaluated).\nIf all expressions are false, the suite of the ``else`` clause, if\npresent, is executed.\n\n\nThe ``while`` statement\n=======================\n\nThe ``while`` statement is used for repeated execution as long as an\nexpression is true:\n\n   while_stmt ::= "while" expression ":" suite\n                  ["else" ":" suite]\n\nThis repeatedly tests the expression and, if it is true, executes the\nfirst suite; if the expression is false (which may be the first time\nit is tested) the suite of the ``else`` clause, if present, is\nexecuted and the loop terminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ngoes back to testing the expression.\n\n\nThe ``for`` statement\n=====================\n\nThe ``for`` statement is used to iterate over the elements of a\nsequence (such as a string, tuple or list) or other iterable object:\n\n   for_stmt ::= "for" target_list "in" expression_list ":" suite\n                ["else" ":" suite]\n\nThe expression list is evaluated once; it should yield an iterable\nobject.  An iterator is created for the result of the\n``expression_list``.  The suite is then executed once for each item\nprovided by the iterator, in the order of ascending indices.  Each\nitem in turn is assigned to the target list using the standard rules\nfor assignments (see *Assignment statements*), and then the suite is\nexecuted.  When the items are exhausted (which is immediately when the\nsequence is empty or an iterator raises a ``StopIteration``\nexception), the suite in the ``else`` clause, if present, is executed,\nand the loop terminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ncontinues with the next item, or with the ``else`` clause if there was\nno next item.\n\nThe suite may assign to the variable(s) in the target list; this does\nnot affect the next item assigned to it.\n\nNames in the target list are not deleted when the loop is finished,\nbut if the sequence is empty, it will not have been assigned to at all\nby the loop.  Hint: the built-in function ``range()`` returns an\niterator of integers suitable to emulate the effect of Pascal\'s ``for\ni := a to b do``; e.g., ``list(range(3))`` returns the list ``[0, 1,\n2]``.\n\nNote: There is a subtlety when the sequence is being modified by the loop\n  (this can only occur for mutable sequences, i.e. lists).  An\n  internal counter is used to keep track of which item is used next,\n  and this is incremented on each iteration.  When this counter has\n  reached the length of the sequence the loop terminates.  This means\n  that if the suite deletes the current (or a previous) item from the\n  sequence, the next item will be skipped (since it gets the index of\n  the current item which has already been treated).  Likewise, if the\n  suite inserts an item in the sequence before the current item, the\n  current item will be treated again the next time through the loop.\n  This can lead to nasty bugs that can be avoided by making a\n  temporary copy using a slice of the whole sequence, e.g.,\n\n     for x in a[:]:\n         if x < 0: a.remove(x)\n\n\nThe ``try`` statement\n=====================\n\nThe ``try`` statement specifies exception handlers and/or cleanup code\nfor a group of statements:\n\n   try_stmt  ::= try1_stmt | try2_stmt\n   try1_stmt ::= "try" ":" suite\n                 ("except" [expression ["as" target]] ":" suite)+\n                 ["else" ":" suite]\n                 ["finally" ":" suite]\n   try2_stmt ::= "try" ":" suite\n                 "finally" ":" suite\n\nThe ``except`` clause(s) specify one or more exception handlers. When\nno exception occurs in the ``try`` clause, no exception handler is\nexecuted. When an exception occurs in the ``try`` suite, a search for\nan exception handler is started.  This search inspects the except\nclauses in turn until one is found that matches the exception.  An\nexpression-less except clause, if present, must be last; it matches\nany exception.  For an except clause with an expression, that\nexpression is evaluated, and the clause matches the exception if the\nresulting object is "compatible" with the exception.  An object is\ncompatible with an exception if it is the class or a base class of the\nexception object or a tuple containing an item compatible with the\nexception.\n\nIf no except clause matches the exception, the search for an exception\nhandler continues in the surrounding code and on the invocation stack.\n[1]\n\nIf the evaluation of an expression in the header of an except clause\nraises an exception, the original search for a handler is canceled and\na search starts for the new exception in the surrounding code and on\nthe call stack (it is treated as if the entire ``try`` statement\nraised the exception).\n\nWhen a matching except clause is found, the exception is assigned to\nthe target specified after the ``as`` keyword in that except clause,\nif present, and the except clause\'s suite is executed.  All except\nclauses must have an executable block.  When the end of this block is\nreached, execution continues normally after the entire try statement.\n(This means that if two nested handlers exist for the same exception,\nand the exception occurs in the try clause of the inner handler, the\nouter handler will not handle the exception.)\n\nWhen an exception has been assigned using ``as target``, it is cleared\nat the end of the except clause.  This is as if\n\n   except E as N:\n       foo\n\nwas translated to\n\n   except E as N:\n       try:\n           foo\n       finally:\n           N = None\n           del N\n\nThat means that you have to assign the exception to a different name\nif you want to be able to refer to it after the except clause.  The\nreason for this is that with the traceback attached to them,\nexceptions will form a reference cycle with the stack frame, keeping\nall locals in that frame alive until the next garbage collection\noccurs.\n\nBefore an except clause\'s suite is executed, details about the\nexception are stored in the ``sys`` module and can be access via\n``sys.exc_info()``. ``sys.exc_info()`` returns a 3-tuple consisting\nof: ``exc_type``, the exception class; ``exc_value``, the exception\ninstance; ``exc_traceback``, a traceback object (see section *The\nstandard type hierarchy*) identifying the point in the program where\nthe exception occurred. ``sys.exc_info()`` values are restored to\ntheir previous values (before the call) when returning from a function\nthat handled an exception.\n\nThe optional ``else`` clause is executed if and when control flows off\nthe end of the ``try`` clause. [2] Exceptions in the ``else`` clause\nare not handled by the preceding ``except`` clauses.\n\nIf ``finally`` is present, it specifies a \'cleanup\' handler.  The\n``try`` clause is executed, including any ``except`` and ``else``\nclauses.  If an exception occurs in any of the clauses and is not\nhandled, the exception is temporarily saved. The ``finally`` clause is\nexecuted.  If there is a saved exception, it is re-raised at the end\nof the ``finally`` clause. If the ``finally`` clause raises another\nexception or executes a ``return`` or ``break`` statement, the saved\nexception is lost.  The exception information is not available to the\nprogram during execution of the ``finally`` clause.\n\nWhen a ``return``, ``break`` or ``continue`` statement is executed in\nthe ``try`` suite of a ``try``...``finally`` statement, the\n``finally`` clause is also executed \'on the way out.\' A ``continue``\nstatement is illegal in the ``finally`` clause. (The reason is a\nproblem with the current implementation --- this restriction may be\nlifted in the future).\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information on using the ``raise`` statement to\ngenerate exceptions may be found in section *The raise statement*.\n\n\nThe ``with`` statement\n======================\n\nThe ``with`` statement is used to wrap the execution of a block with\nmethods defined by a context manager (see section *With Statement\nContext Managers*). This allows common\n``try``...``except``...``finally`` usage patterns to be encapsulated\nfor convenient reuse.\n\n   with_stmt ::= "with" with_item ("," with_item)* ":" suite\n   with_item ::= expression ["as" target]\n\nThe execution of the ``with`` statement with one "item" proceeds as\nfollows:\n\n1. The context expression is evaluated to obtain a context manager.\n\n2. The context manager\'s ``__enter__()`` method is invoked.\n\n3. If a target was included in the ``with`` statement, the return\n   value from ``__enter__()`` is assigned to it.\n\n   Note: The ``with`` statement guarantees that if the ``__enter__()``\n     method returns without an error, then ``__exit__()`` will always\n     be called.  Thus, if an error occurs during the assignment to the\n     target list, it will be treated the same as an error occurring\n     within the suite would be.  See step 5 below.\n\n4. The suite is executed.\n\n5. The context manager\'s ``__exit__()`` method is invoked.  If an\n   exception caused the suite to be exited, its type, value, and\n   traceback are passed as arguments to ``__exit__()``. Otherwise,\n   three ``None`` arguments are supplied.\n\n   If the suite was exited due to an exception, and the return value\n   from the ``__exit__()`` method was false, the exception is\n   reraised.  If the return value was true, the exception is\n   suppressed, and execution continues with the statement following\n   the ``with`` statement.\n\n   If the suite was exited for any reason other than an exception, the\n   return value from ``__exit__()`` is ignored, and execution proceeds\n   at the normal location for the kind of exit that was taken.\n\nWith more than one item, the context managers are processed as if\nmultiple ``with`` statements were nested:\n\n   with A() as a, B() as b:\n       suite\n\nis equivalent to\n\n   with A() as a:\n       with B() as b:\n           suite\n\nChanged in version 3.1: Support for multiple context expressions.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n\n\nFunction definitions\n====================\n\nA function definition defines a user-defined function object (see\nsection *The standard type hierarchy*):\n\n   funcdef        ::= [decorators] "def" funcname "(" [parameter_list] ")" ["->" expression] ":" suite\n   decorators     ::= decorator+\n   decorator      ::= "@" dotted_name ["(" [argument_list [","]] ")"] NEWLINE\n   dotted_name    ::= identifier ("." identifier)*\n   parameter_list ::= (defparameter ",")*\n                      (  "*" [parameter] ("," defparameter)*\n                      [, "**" parameter]\n                      | "**" parameter\n                      | defparameter [","] )\n   parameter      ::= identifier [":" expression]\n   defparameter   ::= parameter ["=" expression]\n   funcname       ::= identifier\n\nA function definition is an executable statement.  Its execution binds\nthe function name in the current local namespace to a function object\n(a wrapper around the executable code for the function).  This\nfunction object contains a reference to the current global namespace\nas the global namespace to be used when the function is called.\n\nThe function definition does not execute the function body; this gets\nexecuted only when the function is called. [3]\n\nA function definition may be wrapped by one or more *decorator*\nexpressions. Decorator expressions are evaluated when the function is\ndefined, in the scope that contains the function definition.  The\nresult must be a callable, which is invoked with the function object\nas the only argument. The returned value is bound to the function name\ninstead of the function object.  Multiple decorators are applied in\nnested fashion. For example, the following code\n\n   @f1(arg)\n   @f2\n   def func(): pass\n\nis equivalent to\n\n   def func(): pass\n   func = f1(arg)(f2(func))\n\nWhen one or more parameters have the form *parameter* ``=``\n*expression*, the function is said to have "default parameter values."\nFor a parameter with a default value, the corresponding argument may\nbe omitted from a call, in which case the parameter\'s default value is\nsubstituted.  If a parameter has a default value, all following\nparameters up until the "``*``" must also have a default value ---\nthis is a syntactic restriction that is not expressed by the grammar.\n\n**Default parameter values are evaluated when the function definition\nis executed.** This means that the expression is evaluated once, when\nthe function is defined, and that that same "pre-computed" value is\nused for each call.  This is especially important to understand when a\ndefault parameter is a mutable object, such as a list or a dictionary:\nif the function modifies the object (e.g. by appending an item to a\nlist), the default value is in effect modified. This is generally not\nwhat was intended.  A way around this is to use ``None`` as the\ndefault, and explicitly test for it in the body of the function, e.g.:\n\n   def whats_on_the_telly(penguin=None):\n       if penguin is None:\n           penguin = []\n       penguin.append("property of the zoo")\n       return penguin\n\nFunction call semantics are described in more detail in section\n*Calls*. A function call always assigns values to all parameters\nmentioned in the parameter list, either from position arguments, from\nkeyword arguments, or from default values.  If the form\n"``*identifier``" is present, it is initialized to a tuple receiving\nany excess positional parameters, defaulting to the empty tuple.  If\nthe form "``**identifier``" is present, it is initialized to a new\ndictionary receiving any excess keyword arguments, defaulting to a new\nempty dictionary. Parameters after "``*``" or "``*identifier``" are\nkeyword-only parameters and may only be passed used keyword arguments.\n\nParameters may have annotations of the form "``: expression``"\nfollowing the parameter name.  Any parameter may have an annotation\neven those of the form ``*identifier`` or ``**identifier``.  Functions\nmay have "return" annotation of the form "``-> expression``" after the\nparameter list.  These annotations can be any valid Python expression\nand are evaluated when the function definition is executed.\nAnnotations may be evaluated in a different order than they appear in\nthe source code.  The presence of annotations does not change the\nsemantics of a function.  The annotation values are available as\nvalues of a dictionary keyed by the parameters\' names in the\n``__annotations__`` attribute of the function object.\n\nIt is also possible to create anonymous functions (functions not bound\nto a name), for immediate use in expressions.  This uses lambda forms,\ndescribed in section *Lambdas*.  Note that the lambda form is merely a\nshorthand for a simplified function definition; a function defined in\na "``def``" statement can be passed around or assigned to another name\njust like a function defined by a lambda form.  The "``def``" form is\nactually more powerful since it allows the execution of multiple\nstatements and annotations.\n\n**Programmer\'s note:** Functions are first-class objects.  A "``def``"\nform executed inside a function definition defines a local function\nthat can be returned or passed around.  Free variables used in the\nnested function can access the local variables of the function\ncontaining the def.  See section *Naming and binding* for details.\n\n\nClass definitions\n=================\n\nA class definition defines a class object (see section *The standard\ntype hierarchy*):\n\n   classdef    ::= [decorators] "class" classname [inheritance] ":" suite\n   inheritance ::= "(" [expression_list] ")"\n   classname   ::= identifier\n\nA class definition is an executable statement.  It first evaluates the\ninheritance list, if present.  Each item in the inheritance list\nshould evaluate to a class object or class type which allows\nsubclassing.  The class\'s suite is then executed in a new execution\nframe (see section *Naming and binding*), using a newly created local\nnamespace and the original global namespace. (Usually, the suite\ncontains only function definitions.)  When the class\'s suite finishes\nexecution, its execution frame is discarded but its local namespace is\nsaved. [4] A class object is then created using the inheritance list\nfor the base classes and the saved local namespace for the attribute\ndictionary.  The class name is bound to this class object in the\noriginal local namespace.\n\nClasses can also be decorated; as with functions,\n\n   @f1(arg)\n   @f2\n   class Foo: pass\n\nis equivalent to\n\n   class Foo: pass\n   Foo = f1(arg)(f2(Foo))\n\n**Programmer\'s note:** Variables defined in the class definition are\nclass variables; they are shared by instances. Instance variables can\nbe set in a method with ``self.name = value``.  Both class and\ninstance variables are accessible through the notation\n"``self.name``", and an instance variable hides a class variable with\nthe same name when accessed in this way.  Class variables can be used\nas defaults for instance variables, but using mutable values there can\nlead to unexpected results.  Descriptors can be used to create\ninstance variables with different implementation details.\n\nSee also:\n\n   **PEP 3129** - Class Decorators\n\nClass definitions, like function definitions, may be wrapped by one or\nmore *decorator* expressions.  The evaluation rules for the decorator\nexpressions are the same as for functions.  The result must be a class\nobject, which is then bound to the class name.\n\n-[ Footnotes ]-\n\n[1] The exception is propagated to the invocation stack only if there\n    is no ``finally`` clause that negates the exception.\n\n[2] Currently, control "flows off the end" except in the case of an\n    exception or the execution of a ``return``, ``continue``, or\n    ``break`` statement.\n\n[3] A string literal appearing as the first statement in the function\n    body is transformed into the function\'s ``__doc__`` attribute and\n    therefore the function\'s *docstring*.\n\n[4] A string literal appearing as the first statement in the class\n    body is transformed into the namespace\'s ``__doc__`` item and\n    therefore the class\'s *docstring*.\n',
+ 'calls': '\nCalls\n*****\n\nA call calls a callable object (e.g., a function) with a possibly\nempty series of arguments:\n\n   call                 ::= primary "(" [argument_list [","] | comprehension] ")"\n   argument_list        ::= positional_arguments ["," keyword_arguments]\n                       ["," "*" expression] ["," keyword_arguments]\n                       ["," "**" expression]\n                     | keyword_arguments ["," "*" expression]\n                       ["," keyword_arguments] ["," "**" expression]\n                     | "*" expression ["," keyword_arguments] ["," "**" expression]\n                     | "**" expression\n   positional_arguments ::= expression ("," expression)*\n   keyword_arguments    ::= keyword_item ("," keyword_item)*\n   keyword_item         ::= identifier "=" expression\n\nA trailing comma may be present after the positional and keyword\narguments but does not affect the semantics.\n\nThe primary must evaluate to a callable object (user-defined\nfunctions, built-in functions, methods of built-in objects, class\nobjects, methods of class instances, and all objects having a\n``__call__()`` method are callable).  All argument expressions are\nevaluated before the call is attempted.  Please refer to section\n*Function definitions* for the syntax of formal parameter lists.\n\nIf keyword arguments are present, they are first converted to\npositional arguments, as follows.  First, a list of unfilled slots is\ncreated for the formal parameters.  If there are N positional\narguments, they are placed in the first N slots.  Next, for each\nkeyword argument, the identifier is used to determine the\ncorresponding slot (if the identifier is the same as the first formal\nparameter name, the first slot is used, and so on).  If the slot is\nalready filled, a ``TypeError`` exception is raised. Otherwise, the\nvalue of the argument is placed in the slot, filling it (even if the\nexpression is ``None``, it fills the slot).  When all arguments have\nbeen processed, the slots that are still unfilled are filled with the\ncorresponding default value from the function definition.  (Default\nvalues are calculated, once, when the function is defined; thus, a\nmutable object such as a list or dictionary used as default value will\nbe shared by all calls that don\'t specify an argument value for the\ncorresponding slot; this should usually be avoided.)  If there are any\nunfilled slots for which no default value is specified, a\n``TypeError`` exception is raised.  Otherwise, the list of filled\nslots is used as the argument list for the call.\n\n**CPython implementation detail:** An implementation may provide\nbuilt-in functions whose positional parameters do not have names, even\nif they are \'named\' for the purpose of documentation, and which\ntherefore cannot be supplied by keyword.  In CPython, this is the case\nfor functions implemented in C that use ``PyArg_ParseTuple()`` to\nparse their arguments.\n\nIf there are more positional arguments than there are formal parameter\nslots, a ``TypeError`` exception is raised, unless a formal parameter\nusing the syntax ``*identifier`` is present; in this case, that formal\nparameter receives a tuple containing the excess positional arguments\n(or an empty tuple if there were no excess positional arguments).\n\nIf any keyword argument does not correspond to a formal parameter\nname, a ``TypeError`` exception is raised, unless a formal parameter\nusing the syntax ``**identifier`` is present; in this case, that\nformal parameter receives a dictionary containing the excess keyword\narguments (using the keywords as keys and the argument values as\ncorresponding values), or a (new) empty dictionary if there were no\nexcess keyword arguments.\n\nIf the syntax ``*expression`` appears in the function call,\n``expression`` must evaluate to a sequence.  Elements from this\nsequence are treated as if they were additional positional arguments;\nif there are positional arguments *x1*,..., *xN*, and ``expression``\nevaluates to a sequence *y1*, ..., *yM*, this is equivalent to a call\nwith M+N positional arguments *x1*, ..., *xN*, *y1*, ..., *yM*.\n\nA consequence of this is that although the ``*expression`` syntax may\nappear *after* some keyword arguments, it is processed *before* the\nkeyword arguments (and the ``**expression`` argument, if any -- see\nbelow).  So:\n\n   >>> def f(a, b):\n   ...  print(a, b)\n   ...\n   >>> f(b=1, *(2,))\n   2 1\n   >>> f(a=1, *(2,))\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in ?\n   TypeError: f() got multiple values for keyword argument \'a\'\n   >>> f(1, *(2,))\n   1 2\n\nIt is unusual for both keyword arguments and the ``*expression``\nsyntax to be used in the same call, so in practice this confusion does\nnot arise.\n\nIf the syntax ``**expression`` appears in the function call,\n``expression`` must evaluate to a mapping, the contents of which are\ntreated as additional keyword arguments.  In the case of a keyword\nappearing in both ``expression`` and as an explicit keyword argument,\na ``TypeError`` exception is raised.\n\nFormal parameters using the syntax ``*identifier`` or ``**identifier``\ncannot be used as positional argument slots or as keyword argument\nnames.\n\nA call always returns some value, possibly ``None``, unless it raises\nan exception.  How this value is computed depends on the type of the\ncallable object.\n\nIf it is---\n\na user-defined function:\n   The code block for the function is executed, passing it the\n   argument list.  The first thing the code block will do is bind the\n   formal parameters to the arguments; this is described in section\n   *Function definitions*.  When the code block executes a ``return``\n   statement, this specifies the return value of the function call.\n\na built-in function or method:\n   The result is up to the interpreter; see *Built-in Functions* for\n   the descriptions of built-in functions and methods.\n\na class object:\n   A new instance of that class is returned.\n\na class instance method:\n   The corresponding user-defined function is called, with an argument\n   list that is one longer than the argument list of the call: the\n   instance becomes the first argument.\n\na class instance:\n   The class must define a ``__call__()`` method; the effect is then\n   the same as if that method was called.\n',

+ 'comparisons': '\nComparisons\n***********\n\nUnlike C, all comparison operations in Python have the same priority,\nwhich is lower than that of any arithmetic, shifting or bitwise\noperation.  Also unlike C, expressions like ``a < b < c`` have the\ninterpretation that is conventional in mathematics:\n\n   comparison    ::= or_expr ( comp_operator or_expr )*\n   comp_operator ::= "<" | ">" | "==" | ">=" | "<=" | "!="\n                     | "is" ["not"] | ["not"] "in"\n\nComparisons yield boolean values: ``True`` or ``False``.\n\nComparisons can be chained arbitrarily, e.g., ``x < y <= z`` is\nequivalent to ``x < y and y <= z``, except that ``y`` is evaluated\nonly once (but in both cases ``z`` is not evaluated at all when ``x <\ny`` is found to be false).\n\nFormally, if *a*, *b*, *c*, ..., *y*, *z* are expressions and *op1*,\n*op2*, ..., *opN* are comparison operators, then ``a op1 b op2 c ... y\nopN z`` is equivalent to ``a op1 b and b op2 c and ... y opN z``,\nexcept that each expression is evaluated at most once.\n\nNote that ``a op1 b op2 c`` doesn\'t imply any kind of comparison\nbetween *a* and *c*, so that, e.g., ``x < y > z`` is perfectly legal\n(though perhaps not pretty).\n\nThe operators ``<``, ``>``, ``==``, ``>=``, ``<=``, and ``!=`` compare\nthe values of two objects.  The objects need not have the same type.\nIf both are numbers, they are converted to a common type.  Otherwise,\nthe ``==`` and ``!=`` operators *always* consider objects of different\ntypes to be unequal, while the ``<``, ``>``, ``>=`` and ``<=``\noperators raise a ``TypeError`` when comparing objects of different\ntypes that do not implement these operators for the given pair of\ntypes.  You can control comparison behavior of objects of non-built-in\ntypes by defining rich comparison methods like ``__gt__()``, described\nin section *Basic customization*.\n\nComparison of objects of the same type depends on the type:\n\n* Numbers are compared arithmetically.\n\n* The values ``float(\'NaN\')`` and ``Decimal(\'NaN\')`` are special. The\n  are identical to themselves, ``x is x`` but are not equal to\n  themselves, ``x != x``.  Additionally, comparing any value to a\n  not-a-number value will return ``False``.  For example, both ``3 <\n  float(\'NaN\')`` and ``float(\'NaN\') < 3`` will return ``False``.\n\n* Bytes objects are compared lexicographically using the numeric\n  values of their elements.\n\n* Strings are compared lexicographically using the numeric equivalents\n  (the result of the built-in function ``ord()``) of their characters.\n  [3] String and bytes object can\'t be compared!\n\n* Tuples and lists are compared lexicographically using comparison of\n  corresponding elements.  This means that to compare equal, each\n  element must compare equal and the two sequences must be of the same\n  type and have the same length.\n\n  If not equal, the sequences are ordered the same as their first\n  differing elements.  For example, ``[1,2,x] <= [1,2,y]`` has the\n  same value as ``x <= y``.  If the corresponding element does not\n  exist, the shorter sequence is ordered first (for example, ``[1,2] <\n  [1,2,3]``).\n\n* Mappings (dictionaries) compare equal if and only if they have the\n  same ``(key, value)`` pairs. Order comparisons ``(\'<\', \'<=\', \'>=\',\n  \'>\')`` raise ``TypeError``.\n\n* Sets and frozensets define comparison operators to mean subset and\n  superset tests.  Those relations do not define total orderings (the\n  two sets ``{1,2}`` and {2,3} are not equal, nor subsets of one\n  another, nor supersets of one another).  Accordingly, sets are not\n  appropriate arguments for functions which depend on total ordering.\n  For example, ``min()``, ``max()``, and ``sorted()`` produce\n  undefined results given a list of sets as inputs.\n\n* Most other objects of built-in types compare unequal unless they are\n  the same object; the choice whether one object is considered smaller\n  or larger than another one is made arbitrarily but consistently\n  within one execution of a program.\n\nComparison of objects of the differing types depends on whether either\nof the types provide explicit support for the comparison.  Most\nnumeric types can be compared with one another, but comparisons of\n``float`` and ``Decimal`` are not supported to avoid the inevitable\nconfusion arising from representation issues such as ``float(\'1.1\')``\nbeing inexactly represented and therefore not exactly equal to\n``Decimal(\'1.1\')`` which is.  When cross-type comparison is not\nsupported, the comparison method returns ``NotImplemented``.  This can\ncreate the illusion of non-transitivity between supported cross-type\ncomparisons and unsupported comparisons.  For example, ``Decimal(2) ==\n2`` and ``2 == float(2)`` but ``Decimal(2) != float(2)``.\n\nThe operators ``in`` and ``not in`` test for membership.  ``x in s``\nevaluates to true if *x* is a member of *s*, and false otherwise.  ``x\nnot in s`` returns the negation of ``x in s``.  All built-in sequences\nand set types support this as well as dictionary, for which ``in``\ntests whether a the dictionary has a given key. For container types\nsuch as list, tuple, set, frozenset, dict, or collections.deque, the\nexpression ``x in y`` is equivalent to ``any(x is e or x == e for e in\ny)``.\n\nFor the string and bytes types, ``x in y`` is true if and only if *x*\nis a substring of *y*.  An equivalent test is ``y.find(x) != -1``.\nEmpty strings are always considered to be a substring of any other\nstring, so ``"" in "abc"`` will return ``True``.\n\nFor user-defined classes which define the ``__contains__()`` method,\n``x in y`` is true if and only if ``y.__contains__(x)`` is true.\n\nFor user-defined classes which do not define ``__contains__()`` but do\ndefine ``__iter__()``, ``x in y`` is true if some value ``z`` with ``x\n== z`` is produced while iterating over ``y``.  If an exception is\nraised during the iteration, it is as if ``in`` raised that exception.\n\nLastly, the old-style iteration protocol is tried: if a class defines\n``__getitem__()``, ``x in y`` is true if and only if there is a non-\nnegative integer index *i* such that ``x == y[i]``, and all lower\ninteger indices do not raise ``IndexError`` exception.  (If any other\nexception is raised, it is as if ``in`` raised that exception).\n\nThe operator ``not in`` is defined to have the inverse true value of\n``in``.\n\nThe operators ``is`` and ``is not`` test for object identity: ``x is\ny`` is true if and only if *x* and *y* are the same object.  ``x is\nnot y`` yields the inverse truth value.

+ 'compound': '\nCompound statements\n*******************\n\nCompound statements contain (groups of) other statements; they affect\nor control the execution of those other statements in some way.  In\ngeneral, compound statements span multiple lines, although in simple\nincarnations a whole compound statement may be contained in one line.\n\nThe ``if``, ``while`` and ``for`` statements implement traditional\ncontrol flow constructs.  ``try`` specifies exception handlers and/or\ncleanup code for a group of statements, while the ``with`` statement\nallows the execution of initialization and finalization code around a\nblock of code.  Function and class definitions are also syntactically\ncompound statements.\n\nCompound statements consist of one or more \'clauses.\'  A clause\nconsists of a header and a \'suite.\'  The clause headers of a\nparticular compound statement are all at the same indentation level.\nEach clause header begins with a uniquely identifying keyword and ends\nwith a colon.  A suite is a group of statements controlled by a\nclause.  A suite can be one or more semicolon-separated simple\nstatements on the same line as the header, following the header\'s\ncolon, or it can be one or more indented statements on subsequent\nlines.  Only the latter form of suite can contain nested compound\nstatements; the following is illegal, mostly because it wouldn\'t be\nclear to which ``if`` clause a following ``else`` clause would belong:\n\n   if test1: if test2: print(x)\n\nAlso note that the semicolon binds tighter than the colon in this\ncontext, so that in the following example, either all or none of the\n``print()`` calls are executed:\n\n   if x < y < z: print(x); print(y); print(z)\n\nSummarizing:\n\n   compound_stmt ::= if_stmt\n                     | while_stmt\n                     | for_stmt\n                     | try_stmt\n                     | with_stmt\n                     | funcdef\n                     | classdef\n   suite         ::= stmt_list NEWLINE | NEWLINE INDENT statement+ DEDENT\n   statement     ::= stmt_list NEWLINE | compound_stmt\n   stmt_list     ::= simple_stmt (";" simple_stmt)* [";"]\n\nNote that statements always end in a ``NEWLINE`` possibly followed by\na ``DEDENT``.  Also note that optional continuation clauses always\nbegin with a keyword that cannot start a statement, thus there are no\nambiguities (the \'dangling ``else``\' problem is solved in Python by\nrequiring nested ``if`` statements to be indented).\n\nThe formatting of the grammar rules in the following sections places\neach clause on a separate line for clarity.\n\n\nThe ``if`` statement\n====================\n\nThe ``if`` statement is used for conditional execution:\n\n   if_stmt ::= "if" expression ":" suite\n               ( "elif" expression ":" suite )*\n               ["else" ":" suite]\n\nIt selects exactly one of the suites by evaluating the expressions one\nby one until one is found to be true (see section *Boolean operations*\nfor the definition of true and false); then that suite is executed\n(and no other part of the ``if`` statement is executed or evaluated).\nIf all expressions are false, the suite of the ``else`` clause, if\npresent, is executed.\n\n\nThe ``while`` statement\n=======================\n\nThe ``while`` statement is used for repeated execution as long as an\nexpression is true:\n\n   while_stmt ::= "while" expression ":" suite\n                  ["else" ":" suite]\n\nThis repeatedly tests the expression and, if it is true, executes the\nfirst suite; if the expression is false (which may be the first time\nit is tested) the suite of the ``else`` clause, if present, is\nexecuted and the loop terminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ngoes back to testing the expression.\n\n\nThe ``for`` statement\n=====================\n\nThe ``for`` statement is used to iterate over the elements of a\nsequence (such as a string, tuple or list) or other iterable object:\n\n   for_stmt ::= "for" target_list "in" expression_list ":" suite\n                ["else" ":" suite]\n\nThe expression list is evaluated once; it should yield an iterable\nobject.  An iterator is created for the result of the\n``expression_list``.  The suite is then executed once for each item\nprovided by the iterator, in the order of ascending indices.  Each\nitem in turn is assigned to the target list using the standard rules\nfor assignments (see *Assignment statements*), and then the suite is\nexecuted.  When the items are exhausted (which is immediately when the\nsequence is empty or an iterator raises a ``StopIteration``\nexception), the suite in the ``else`` clause, if present, is executed,\nand the loop terminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ncontinues with the next item, or with the ``else`` clause if there was\nno next item.\n\nThe suite may assign to the variable(s) in the target list; this does\nnot affect the next item assigned to it.\n\nNames in the target list are not deleted when the loop is finished,\nbut if the sequence is empty, it will not have been assigned to at all\nby the loop.  Hint: the built-in function ``range()`` returns an\niterator of integers suitable to emulate the effect of Pascal\'s ``for\ni := a to b do``; e.g., ``list(range(3))`` returns the list ``[0, 1,\n2]``.\n\nNote: There is a subtlety when the sequence is being modified by the loop\n  (this can only occur for mutable sequences, i.e. lists).  An\n  internal counter is used to keep track of which item is used next,\n  and this is incremented on each iteration.  When this counter has\n  reached the length of the sequence the loop terminates.  This means\n  that if the suite deletes the current (or a previous) item from the\n  sequence, the next item will be skipped (since it gets the index of\n  the current item which has already been treated).  Likewise, if the\n  suite inserts an item in the sequence before the current item, the\n  current item will be treated again the next time through the loop.\n  This can lead to nasty bugs that can be avoided by making a\n  temporary copy using a slice of the whole sequence, e.g.,\n\n     for x in a[:]:\n         if x < 0: a.remove(x)\n\n\nThe ``try`` statement\n=====================\n\nThe ``try`` statement specifies exception handlers and/or cleanup code\nfor a group of statements:\n\n   try_stmt  ::= try1_stmt | try2_stmt\n   try1_stmt ::= "try" ":" suite\n                 ("except" [expression ["as" target]] ":" suite)+\n                 ["else" ":" suite]\n                 ["finally" ":" suite]\n   try2_stmt ::= "try" ":" suite\n                 "finally" ":" suite\n\nThe ``except`` clause(s) specify one or more exception handlers. When\nno exception occurs in the ``try`` clause, no exception handler is\nexecuted. When an exception occurs in the ``try`` suite, a search for\nan exception handler is started.  This search inspects the except\nclauses in turn until one is found that matches the exception.  An\nexpression-less except clause, if present, must be last; it matches\nany exception.  For an except clause with an expression, that\nexpression is evaluated, and the clause matches the exception if the\nresulting object is "compatible" with the exception.  An object is\ncompatible with an exception if it is the class or a base class of the\nexception object or a tuple containing an item compatible with the\nexception.\n\nIf no except clause matches the exception, the search for an exception\nhandler continues in the surrounding code and on the invocation stack.\n[1]\n\nIf the evaluation of an expression in the header of an except clause\nraises an exception, the original search for a handler is canceled and\na search starts for the new exception in the surrounding code and on\nthe call stack (it is treated as if the entire ``try`` statement\nraised the exception).\n\nWhen a matching except clause is found, the exception is assigned to\nthe target specified after the ``as`` keyword in that except clause,\nif present, and the except clause\'s suite is executed.  All except\nclauses must have an executable block.  When the end of this block is\nreached, execution continues normally after the entire try statement.\n(This means that if two nested handlers exist for the same exception,\nand the exception occurs in the try clause of the inner handler, the\nouter handler will not handle the exception.)\n\nWhen an exception has been assigned using ``as target``, it is cleared\nat the end of the except clause.  This is as if\n\n   except E as N:\n       foo\n\nwas translated to\n\n   except E as N:\n       try:\n           foo\n       finally:\n           del N\n\nThis means the exception must be assigned to a different name to be\nable to refer to it after the except clause.  Exceptions are cleared\nbecause with the traceback attached to them, they form a reference\ncycle with the stack frame, keeping all locals in that frame alive\nuntil the next garbage collection occurs.\n\nBefore an except clause\'s suite is executed, details about the\nexception are stored in the ``sys`` module and can be access via\n``sys.exc_info()``. ``sys.exc_info()`` returns a 3-tuple consisting of\nthe exception class, the exception instance and a traceback object\n(see section *The standard type hierarchy*) identifying the point in\nthe program where the exception occurred.  ``sys.exc_info()`` values\nare restored to their previous values (before the call) when returning\nfrom a function that handled an exception.\n\nThe optional ``else`` clause is executed if and when control flows off\nthe end of the ``try`` clause. [2] Exceptions in the ``else`` clause\nare not handled by the preceding ``except`` clauses.\n\nIf ``finally`` is present, it specifies a \'cleanup\' handler.  The\n``try`` clause is executed, including any ``except`` and ``else``\nclauses.  If an exception occurs in any of the clauses and is not\nhandled, the exception is temporarily saved. The ``finally`` clause is\nexecuted.  If there is a saved exception, it is re-raised at the end\nof the ``finally`` clause. If the ``finally`` clause raises another\nexception or executes a ``return`` or ``break`` statement, the saved\nexception is lost.  The exception information is not available to the\nprogram during execution of the ``finally`` clause.\n\nWhen a ``return``, ``break`` or ``continue`` statement is executed in\nthe ``try`` suite of a ``try``...``finally`` statement, the\n``finally`` clause is also executed \'on the way out.\' A ``continue``\nstatement is illegal in the ``finally`` clause. (The reason is a\nproblem with the current implementation --- this restriction may be\nlifted in the future).\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information on using the ``raise`` statement to\ngenerate exceptions may be found in section *The raise statement*.\n\n\nThe ``with`` statement\n======================\n\nThe ``with`` statement is used to wrap the execution of a block with\nmethods defined by a context manager (see section *With Statement\nContext Managers*). This allows common\n``try``...``except``...``finally`` usage patterns to be encapsulated\nfor convenient reuse.\n\n   with_stmt ::= "with" with_item ("," with_item)* ":" suite\n   with_item ::= expression ["as" target]\n\nThe execution of the ``with`` statement with one "item" proceeds as\nfollows:\n\n1. The context expression (the expression given in the ``with_item``)\n   is evaluated to obtain a context manager.\n\n2. The context manager\'s ``__exit__()`` is loaded for later use.\n\n3. The context manager\'s ``__enter__()`` method is invoked.\n\n4. If a target was included in the ``with`` statement, the return\n   value from ``__enter__()`` is assigned to it.\n\n   Note: The ``with`` statement guarantees that if the ``__enter__()``\n     method returns without an error, then ``__exit__()`` will always\n     be called. Thus, if an error occurs during the assignment to the\n     target list, it will be treated the same as an error occurring\n     within the suite would be. See step 6 below.\n\n5. The suite is executed.\n\n6. The context manager\'s ``__exit__()`` method is invoked.  If an\n   exception caused the suite to be exited, its type, value, and\n   traceback are passed as arguments to ``__exit__()``. Otherwise,\n   three ``None`` arguments are supplied.\n\n   If the suite was exited due to an exception, and the return value\n   from the ``__exit__()`` method was false, the exception is\n   reraised.  If the return value was true, the exception is\n   suppressed, and execution continues with the statement following\n   the ``with`` statement.\n\n   If the suite was exited for any reason other than an exception, the\n   return value from ``__exit__()`` is ignored, and execution proceeds\n   at the normal location for the kind of exit that was taken.\n\nWith more than one item, the context managers are processed as if\nmultiple ``with`` statements were nested:\n\n   with A() as a, B() as b:\n       suite\n\nis equivalent to\n\n   with A() as a:\n       with B() as b:\n           suite\n\nChanged in version 3.1: Support for multiple context expressions.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n\n\nFunction definitions\n====================\n\nA function definition defines a user-defined function object (see\nsection *The standard type hierarchy*):\n\n   funcdef        ::= [decorators] "def" funcname "(" [parameter_list] ")" ["->" expression] ":" suite\n   decorators     ::= decorator+\n   decorator      ::= "@" dotted_name ["(" [argument_list [","]] ")"] NEWLINE\n   dotted_name    ::= identifier ("." identifier)*\n   parameter_list ::= (defparameter ",")*\n                      (  "*" [parameter] ("," defparameter)*\n                      [, "**" parameter]\n                      | "**" parameter\n                      | defparameter [","] )\n   parameter      ::= identifier [":" expression]\n   defparameter   ::= parameter ["=" expression]\n   funcname       ::= identifier\n\nA function definition is an executable statement.  Its execution binds\nthe function name in the current local namespace to a function object\n(a wrapper around the executable code for the function).  This\nfunction object contains a reference to the current global namespace\nas the global namespace to be used when the function is called.\n\nThe function definition does not execute the function body; this gets\nexecuted only when the function is called. [3]\n\nA function definition may be wrapped by one or more *decorator*\nexpressions. Decorator expressions are evaluated when the function is\ndefined, in the scope that contains the function definition.  The\nresult must be a callable, which is invoked with the function object\nas the only argument. The returned value is bound to the function name\ninstead of the function object.  Multiple decorators are applied in\nnested fashion. For example, the following code\n\n   @f1(arg)\n   @f2\n   def func(): pass\n\nis equivalent to\n\n   def func(): pass\n   func = f1(arg)(f2(func))\n\nWhen one or more parameters have the form *parameter* ``=``\n*expression*, the function is said to have "default parameter values."\nFor a parameter with a default value, the corresponding argument may\nbe omitted from a call, in which case the parameter\'s default value is\nsubstituted.  If a parameter has a default value, all following\nparameters up until the "``*``" must also have a default value ---\nthis is a syntactic restriction that is not expressed by the grammar.\n\n**Default parameter values are evaluated when the function definition\nis executed.** This means that the expression is evaluated once, when\nthe function is defined, and that that same "pre-computed" value is\nused for each call.  This is especially important to understand when a\ndefault parameter is a mutable object, such as a list or a dictionary:\nif the function modifies the object (e.g. by appending an item to a\nlist), the default value is in effect modified. This is generally not\nwhat was intended.  A way around this is to use ``None`` as the\ndefault, and explicitly test for it in the body of the function, e.g.:\n\n   def whats_on_the_telly(penguin=None):\n       if penguin is None:\n           penguin = []\n       penguin.append("property of the zoo")\n       return penguin\n\nFunction call semantics are described in more detail in section\n*Calls*. A function call always assigns values to all parameters\nmentioned in the parameter list, either from position arguments, from\nkeyword arguments, or from default values.  If the form\n"``*identifier``" is present, it is initialized to a tuple receiving\nany excess positional parameters, defaulting to the empty tuple.  If\nthe form "``**identifier``" is present, it is initialized to a new\ndictionary receiving any excess keyword arguments, defaulting to a new\nempty dictionary. Parameters after "``*``" or "``*identifier``" are\nkeyword-only parameters and may only be passed used keyword arguments.\n\nParameters may have annotations of the form "``: expression``"\nfollowing the parameter name.  Any parameter may have an annotation\neven those of the form ``*identifier`` or ``**identifier``.  Functions\nmay have "return" annotation of the form "``-> expression``" after the\nparameter list.  These annotations can be any valid Python expression\nand are evaluated when the function definition is executed.\nAnnotations may be evaluated in a different order than they appear in\nthe source code.  The presence of annotations does not change the\nsemantics of a function.  The annotation values are available as\nvalues of a dictionary keyed by the parameters\' names in the\n``__annotations__`` attribute of the function object.\n\nIt is also possible to create anonymous functions (functions not bound\nto a name), for immediate use in expressions.  This uses lambda forms,\ndescribed in section *Lambdas*.  Note that the lambda form is merely a\nshorthand for a simplified function definition; a function defined in\na "``def``" statement can be passed around or assigned to another name\njust like a function defined by a lambda form.  The "``def``" form is\nactually more powerful since it allows the execution of multiple\nstatements and annotations.\n\n**Programmer\'s note:** Functions are first-class objects.  A "``def``"\nform executed inside a function definition defines a local function\nthat can be returned or passed around.  Free variables used in the\nnested function can access the local variables of the function\ncontaining the def.  See section *Naming and binding* for details.\n\n\nClass definitions\n=================\n\nA class definition defines a class object (see section *The standard\ntype hierarchy*):\n\n   classdef    ::= [decorators] "class" classname [inheritance] ":" suite\n   inheritance ::= "(" [argument_list [","] | comprehension] ")"\n   classname   ::= identifier\n\nA class definition is an executable statement.  The inheritance list\nusually gives a list of base classes (see *Customizing class creation*\nfor more advanced uses), so each item in the list should evaluate to a\nclass object which allows subclassing.  Classes without an inheritance\nlist inherit, by default, from the base class ``object``; hence,\n\n   class Foo:\n       pass\n\nis equivalent to\n\n   class Foo(object):\n       pass\n\nThe class\'s suite is then executed in a new execution frame (see\n*Naming and binding*), using a newly created local namespace and the\noriginal global namespace. (Usually, the suite contains mostly\nfunction definitions.)  When the class\'s suite finishes execution, its\nexecution frame is discarded but its local namespace is saved. [4] A\nclass object is then created using the inheritance list for the base\nclasses and the saved local namespace for the attribute dictionary.\nThe class name is bound to this class object in the original local\nnamespace.\n\nClass creation can be customized heavily using *metaclasses*.\n\nClasses can also be decorated: just like when decorating functions,\n\n   @f1(arg)\n   @f2\n   class Foo: pass\n\nis equivalent to\n\n   class Foo: pass\n   Foo = f1(arg)(f2(Foo))\n\nThe evaluation rules for the decorator expressions are the same as for\nfunction decorators.  The result must be a class object, which is then\nbound to the class name.\n\n**Programmer\'s note:** Variables defined in the class definition are\nclass attributes; they are shared by instances.  Instance attributes\ncan be set in a method with ``self.name = value``.  Both class and\ninstance attributes are accessible through the notation\n"``self.name``", and an instance attribute hides a class attribute\nwith the same name when accessed in this way.  Class attributes can be\nused as defaults for instance attributes, but using mutable values\nthere can lead to unexpected results.  *Descriptors* can be used to\ncreate instance variables with different implementation details.\n\nSee also:\n\n   **PEP 3116** - Metaclasses in Python 3 **PEP 3129** - Class\n   Decorators\n\n-[ Footnotes ]-\n\n[1] The exception is propagated to the invocation stack only if there\n    is no ``finally`` clause that negates the exception.\n\n[2] Currently, control "flows off the end" except in the case of an\n    exception or the execution of a ``return``, ``continue``, or\n    ``break`` statement.\n\n[3] A string literal appearing as the first statement in the function\n    body is transformed into the function\'s ``__doc__`` attribute and\n    therefore the function\'s *docstring*.\n\n[4] A string literal appearing as the first statement in the class\n    body is transformed into the namespace\'s ``__doc__`` item and\n    therefore the class\'s *docstring*.\n',
  'context-managers': '\nWith Statement Context Managers\n*******************************\n\nA *context manager* is an object that defines the runtime context to\nbe established when executing a ``with`` statement. The context\nmanager handles the entry into, and the exit from, the desired runtime\ncontext for the execution of the block of code.  Context managers are\nnormally invoked using the ``with`` statement (described in section\n*The with statement*), but can also be used by directly invoking their\nmethods.\n\nTypical uses of context managers include saving and restoring various\nkinds of global state, locking and unlocking resources, closing opened\nfiles, etc.\n\nFor more information on context managers, see *Context Manager Types*.\n\nobject.__enter__(self)\n\n   Enter the runtime context related to this object. The ``with``\n   statement will bind this method\'s return value to the target(s)\n   specified in the ``as`` clause of the statement, if any.\n\nobject.__exit__(self, exc_type, exc_value, traceback)\n\n   Exit the runtime context related to this object. The parameters\n   describe the exception that caused the context to be exited. If the\n   context was exited without an exception, all three arguments will\n   be ``None``.\n\n   If an exception is supplied, and the method wishes to suppress the\n   exception (i.e., prevent it from being propagated), it should\n   return a true value. Otherwise, the exception will be processed\n   normally upon exit from this method.\n\n   Note that ``__exit__()`` methods should not reraise the passed-in\n   exception; this is the caller\'s responsibility.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n',

  'conversions': '\nArithmetic conversions\n**********************\n\nWhen a description of an arithmetic operator below uses the phrase\n"the numeric arguments are converted to a common type," this means\nthat the operator implementation for built-in types works that way:\n\n* If either argument is a complex number, the other is converted to\n  complex;\n\n* otherwise, if either argument is a floating point number, the other\n  is converted to floating point;\n\n* otherwise, both must be integers and no conversion is necessary.\n\nSome additional rules apply for certain operators (e.g., a string left\nargument to the \'%\' operator).  Extensions must define their own\nconversion behavior.\n',
- 'customization': '\nBasic customization\n*******************\n\nobject.__new__(cls[, ...])\n\n   Called to create a new instance of class *cls*.  ``__new__()`` is a\n   static method (special-cased so you need not declare it as such)\n   that takes the class of which an instance was requested as its\n   first argument.  The remaining arguments are those passed to the\n   object constructor expression (the call to the class).  The return\n   value of ``__new__()`` should be the new object instance (usually\n   an instance of *cls*).\n\n   Typical implementations create a new instance of the class by\n   invoking the superclass\'s ``__new__()`` method using\n   ``super(currentclass, cls).__new__(cls[, ...])`` with appropriate\n   arguments and then modifying the newly-created instance as\n   necessary before returning it.\n\n   If ``__new__()`` returns an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will be invoked like\n   ``__init__(self[, ...])``, where *self* is the new instance and the\n   remaining arguments are the same as were passed to ``__new__()``.\n\n   If ``__new__()`` does not return an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will not be invoked.\n\n   ``__new__()`` is intended mainly to allow subclasses of immutable\n   types (like int, str, or tuple) to customize instance creation.  It\n   is also commonly overridden in custom metaclasses in order to\n   customize class creation.\n\nobject.__init__(self[, ...])\n\n   Called when the instance is created.  The arguments are those\n   passed to the class constructor expression.  If a base class has an\n   ``__init__()`` method, the derived class\'s ``__init__()`` method,\n   if any, must explicitly call it to ensure proper initialization of\n   the base class part of the instance; for example:\n   ``BaseClass.__init__(self, [args...])``.  As a special constraint\n   on constructors, no value may be returned; doing so will cause a\n   ``TypeError`` to be raised at runtime.\n\nobject.__del__(self)\n\n   Called when the instance is about to be destroyed.  This is also\n   called a destructor.  If a base class has a ``__del__()`` method,\n   the derived class\'s ``__del__()`` method, if any, must explicitly\n   call it to ensure proper deletion of the base class part of the\n   instance.  Note that it is possible (though not recommended!) for\n   the ``__del__()`` method to postpone destruction of the instance by\n   creating a new reference to it.  It may then be called at a later\n   time when this new reference is deleted.  It is not guaranteed that\n   ``__del__()`` methods are called for objects that still exist when\n   the interpreter exits.\n\n   Note: ``del x`` doesn\'t directly call ``x.__del__()`` --- the former\n     decrements the reference count for ``x`` by one, and the latter\n     is only called when ``x``\'s reference count reaches zero.  Some\n     common situations that may prevent the reference count of an\n     object from going to zero include: circular references between\n     objects (e.g., a doubly-linked list or a tree data structure with\n     parent and child pointers); a reference to the object on the\n     stack frame of a function that caught an exception (the traceback\n     stored in ``sys.exc_info()[2]`` keeps the stack frame alive); or\n     a reference to the object on the stack frame that raised an\n     unhandled exception in interactive mode (the traceback stored in\n     ``sys.last_traceback`` keeps the stack frame alive).  The first\n     situation can only be remedied by explicitly breaking the cycles;\n     the latter two situations can be resolved by storing ``None`` in\n     ``sys.last_traceback``. Circular references which are garbage are\n     detected when the option cycle detector is enabled (it\'s on by\n     default), but can only be cleaned up if there are no Python-\n     level ``__del__()`` methods involved. Refer to the documentation\n     for the ``gc`` module for more information about how\n     ``__del__()`` methods are handled by the cycle detector,\n     particularly the description of the ``garbage`` value.\n\n   Warning: Due to the precarious circumstances under which ``__del__()``\n     methods are invoked, exceptions that occur during their execution\n     are ignored, and a warning is printed to ``sys.stderr`` instead.\n     Also, when ``__del__()`` is invoked in response to a module being\n     deleted (e.g., when execution of the program is done), other\n     globals referenced by the ``__del__()`` method may already have\n     been deleted or in the process of being torn down (e.g. the\n     import machinery shutting down).  For this reason, ``__del__()``\n     methods should do the absolute minimum needed to maintain\n     external invariants.  Starting with version 1.5, Python\n     guarantees that globals whose name begins with a single\n     underscore are deleted from their module before other globals are\n     deleted; if no other references to such globals exist, this may\n     help in assuring that imported modules are still available at the\n     time when the ``__del__()`` method is called.\n\nobject.__repr__(self)\n\n   Called by the ``repr()`` built-in function to compute the\n   "official" string representation of an object.  If at all possible,\n   this should look like a valid Python expression that could be used\n   to recreate an object with the same value (given an appropriate\n   environment).  If this is not possible, a string of the form\n   ``<...some useful description...>`` should be returned. The return\n   value must be a string object. If a class defines ``__repr__()``\n   but not ``__str__()``, then ``__repr__()`` is also used when an\n   "informal" string representation of instances of that class is\n   required.\n\n   This is typically used for debugging, so it is important that the\n   representation is information-rich and unambiguous.\n\nobject.__str__(self)\n\n   Called by the ``str()`` built-in function and by the ``print()``\n   function to compute the "informal" string representation of an\n   object.  This differs from ``__repr__()`` in that it does not have\n   to be a valid Python expression: a more convenient or concise\n   representation may be used instead. The return value must be a\n   string object.\n\nobject.__format__(self, format_spec)\n\n   Called by the ``format()`` built-in function (and by extension, the\n   ``format()`` method of class ``str``) to produce a "formatted"\n   string representation of an object. The ``format_spec`` argument is\n   a string that contains a description of the formatting options\n   desired. The interpretation of the ``format_spec`` argument is up\n   to the type implementing ``__format__()``, however most classes\n   will either delegate formatting to one of the built-in types, or\n   use a similar formatting option syntax.\n\n   See *Format Specification Mini-Language* for a description of the\n   standard formatting syntax.\n\n   The return value must be a string object.\n\nobject.__lt__(self, other)\nobject.__le__(self, other)\nobject.__eq__(self, other)\nobject.__ne__(self, other)\nobject.__gt__(self, other)\nobject.__ge__(self, other)\n\n   These are the so-called "rich comparison" methods. The\n   correspondence between operator symbols and method names is as\n   follows: ``x<y`` calls ``x.__lt__(y)``, ``x<=y`` calls\n   ``x.__le__(y)``, ``x==y`` calls ``x.__eq__(y)``, ``x!=y`` calls\n   ``x.__ne__(y)``, ``x>y`` calls ``x.__gt__(y)``, and ``x>=y`` calls\n   ``x.__ge__(y)``.\n\n   A rich comparison method may return the singleton\n   ``NotImplemented`` if it does not implement the operation for a\n   given pair of arguments. By convention, ``False`` and ``True`` are\n   returned for a successful comparison. However, these methods can\n   return any value, so if the comparison operator is used in a\n   Boolean context (e.g., in the condition of an ``if`` statement),\n   Python will call ``bool()`` on the value to determine if the result\n   is true or false.\n\n   There are no implied relationships among the comparison operators.\n   The truth of ``x==y`` does not imply that ``x!=y`` is false.\n   Accordingly, when defining ``__eq__()``, one should also define\n   ``__ne__()`` so that the operators will behave as expected.  See\n   the paragraph on ``__hash__()`` for some important notes on\n   creating *hashable* objects which support custom comparison\n   operations and are usable as dictionary keys.\n\n   There are no swapped-argument versions of these methods (to be used\n   when the left argument does not support the operation but the right\n   argument does); rather, ``__lt__()`` and ``__gt__()`` are each\n   other\'s reflection, ``__le__()`` and ``__ge__()`` are each other\'s\n   reflection, and ``__eq__()`` and ``__ne__()`` are their own\n   reflection.\n\n   Arguments to rich comparison methods are never coerced.\n\n   To automatically generate ordering operations from a single root\n   operation, see the Total Ordering recipe in the ASPN cookbook.\n\nobject.__hash__(self)\n\n   Called by built-in function ``hash()`` and for operations on\n   members of hashed collections including ``set``, ``frozenset``, and\n   ``dict``.  ``__hash__()`` should return an integer.  The only\n   required property is that objects which compare equal have the same\n   hash value; it is advised to somehow mix together (e.g. using\n   exclusive or) the hash values for the components of the object that\n   also play a part in comparison of objects.\n\n   If a class does not define an ``__eq__()`` method it should not\n   define a ``__hash__()`` operation either; if it defines\n   ``__eq__()`` but not ``__hash__()``, its instances will not be\n   usable as items in hashable collections.  If a class defines\n   mutable objects and implements an ``__eq__()`` method, it should\n   not implement ``__hash__()``, since the implementation of hashable\n   collections requires that a key\'s hash value is immutable (if the\n   object\'s hash value changes, it will be in the wrong hash bucket).\n\n   User-defined classes have ``__eq__()`` and ``__hash__()`` methods\n   by default; with them, all objects compare unequal (except with\n   themselves) and ``x.__hash__()`` returns ``id(x)``.\n\n   Classes which inherit a ``__hash__()`` method from a parent class\n   but change the meaning of ``__eq__()`` such that the hash value\n   returned is no longer appropriate (e.g. by switching to a value-\n   based concept of equality instead of the default identity based\n   equality) can explicitly flag themselves as being unhashable by\n   setting ``__hash__ = None`` in the class definition. Doing so means\n   that not only will instances of the class raise an appropriate\n   ``TypeError`` when a program attempts to retrieve their hash value,\n   but they will also be correctly identified as unhashable when\n   checking ``isinstance(obj, collections.Hashable)`` (unlike classes\n   which define their own ``__hash__()`` to explicitly raise\n   ``TypeError``).\n\n   If a class that overrides ``__eq__()`` needs to retain the\n   implementation of ``__hash__()`` from a parent class, the\n   interpreter must be told this explicitly by setting ``__hash__ =\n   <ParentClass>.__hash__``. Otherwise the inheritance of\n   ``__hash__()`` will be blocked, just as if ``__hash__`` had been\n   explicitly set to ``None``.\n\nobject.__bool__(self)\n\n   Called to implement truth value testing and the built-in operation\n   ``bool()``; should return ``False`` or ``True``, or their integer\n   equivalents ``0`` or ``1``.  When this method is not defined,\n   ``__len__()`` is called, if it is defined, and the object is\n   considered true if its result is nonzero. If a class defines\n   neither ``__len__()`` nor ``__bool__()``, all its instances are\n   considered true.\n',
- 'debugger': '\n``pdb`` --- The Python Debugger\n*******************************\n\nThe module ``pdb`` defines an interactive source code debugger for\nPython programs.  It supports setting (conditional) breakpoints and\nsingle stepping at the source line level, inspection of stack frames,\nsource code listing, and evaluation of arbitrary Python code in the\ncontext of any stack frame.  It also supports post-mortem debugging\nand can be called under program control.\n\nThe debugger is extensible --- it is actually defined as the class\n``Pdb``. This is currently undocumented but easily understood by\nreading the source.  The extension interface uses the modules ``bdb``\n(undocumented) and ``cmd``.\n\nThe debugger\'s prompt is ``(Pdb)``. Typical usage to run a program\nunder control of the debugger is:\n\n   >>> import pdb\n   >>> import mymodule\n   >>> pdb.run(\'mymodule.test()\')\n   > <string>(0)?()\n   (Pdb) continue\n   > <string>(1)?()\n   (Pdb) continue\n   NameError: \'spam\'\n   > <string>(1)?()\n   (Pdb)\n\n``pdb.py`` can also be invoked as a script to debug other scripts.\nFor example:\n\n   python -m pdb myscript.py\n\nWhen invoked as a script, pdb will automatically enter post-mortem\ndebugging if the program being debugged exits abnormally. After post-\nmortem debugging (or after normal exit of the program), pdb will\nrestart the program. Automatic restarting preserves pdb\'s state (such\nas breakpoints) and in most cases is more useful than quitting the\ndebugger upon program\'s exit.\n\nThe typical usage to break into the debugger from a running program is\nto insert\n\n   import pdb; pdb.set_trace()\n\nat the location you want to break into the debugger.  You can then\nstep through the code following this statement, and continue running\nwithout debugger using the ``c`` command.\n\nThe typical usage to inspect a crashed program is:\n\n   >>> import pdb\n   >>> import mymodule\n   >>> mymodule.test()\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in ?\n     File "./mymodule.py", line 4, in test\n       test2()\n     File "./mymodule.py", line 3, in test2\n       print(spam)\n   NameError: spam\n   >>> pdb.pm()\n   > ./mymodule.py(3)test2()\n   -> print(spam)\n   (Pdb)\n\nThe module defines the following functions; each enters the debugger\nin a slightly different way:\n\npdb.run(statement[, globals[, locals]])\n\n   Execute the *statement* (given as a string) under debugger control.\n   The debugger prompt appears before any code is executed; you can\n   set breakpoints and type ``continue``, or you can step through the\n   statement using ``step`` or ``next`` (all these commands are\n   explained below).  The optional *globals* and *locals* arguments\n   specify the environment in which the code is executed; by default\n   the dictionary of the module ``__main__`` is used.  (See the\n   explanation of the built-in ``exec()`` or ``eval()`` functions.)\n\npdb.runeval(expression[, globals[, locals]])\n\n   Evaluate the *expression* (given as a string) under debugger\n   control.  When ``runeval()`` returns, it returns the value of the\n   expression.  Otherwise this function is similar to ``run()``.\n\npdb.runcall(function[, argument, ...])\n\n   Call the *function* (a function or method object, not a string)\n   with the given arguments.  When ``runcall()`` returns, it returns\n   whatever the function call returned.  The debugger prompt appears\n   as soon as the function is entered.\n\npdb.set_trace()\n\n   Enter the debugger at the calling stack frame.  This is useful to\n   hard-code a breakpoint at a given point in a program, even if the\n   code is not otherwise being debugged (e.g. when an assertion\n   fails).\n\npdb.post_mortem([traceback])\n\n   Enter post-mortem debugging of the given *traceback* object.  If no\n   *traceback* is given, it uses the one of the exception that is\n   currently being handled (an exception must be being handled if the\n   default is to be used).\n\npdb.pm()\n\n   Enter post-mortem debugging of the traceback found in\n   ``sys.last_traceback``.\n\nThe ``run_*`` functions and ``set_trace()`` are aliases for\ninstantiating the ``Pdb`` class and calling the method of the same\nname.  If you want to access further features, you have to do this\nyourself:\n\nclass class pdb.Pdb(completekey=\'tab\', stdin=None, stdout=None, skip=None)\n\n   ``Pdb`` is the debugger class.\n\n   The *completekey*, *stdin* and *stdout* arguments are passed to the\n   underlying ``cmd.Cmd`` class; see the description there.\n\n   The *skip* argument, if given, must be an iterable of glob-style\n   module name patterns.  The debugger will not step into frames that\n   originate in a module that matches one of these patterns. [1]\n\n   Example call to enable tracing with *skip*:\n\n      import pdb; pdb.Pdb(skip=[\'django.*\']).set_trace()\n\n   New in version 3.1: The *skip* argument.\n\n   run(statement[, globals[, locals]])\n   runeval(expression[, globals[, locals]])\n   runcall(function[, argument, ...])\n   set_trace()\n\n      See the documentation for the functions explained above.\n',

The interpretation of the ``format_spec`` argument is up\n   to the type implementing ``__format__()``, however most classes\n   will either delegate formatting to one of the built-in types, or\n   use a similar formatting option syntax.\n\n   See *Format Specification Mini-Language* for a description of the\n   standard formatting syntax.\n\n   The return value must be a string object.\n\nobject.__lt__(self, other)\nobject.__le__(self, other)\nobject.__eq__(self, other)\nobject.__ne__(self, other)\nobject.__gt__(self, other)\nobject.__ge__(self, other)\n\n   These are the so-called "rich comparison" methods. The\n   correspondence between operator symbols and method names is as\n   follows: ``x<y`` calls ``x.__lt__(y)``, ``x<=y`` calls\n   ``x.__le__(y)``, ``x==y`` calls ``x.__eq__(y)``, ``x!=y`` calls\n   ``x.__ne__(y)``, ``x>y`` calls ``x.__gt__(y)``, and ``x>=y`` calls\n   ``x.__ge__(y)``.\n\n   A rich comparison method may return the singleton\n   ``NotImplemented`` if it does not implement the operation for a\n   given pair of arguments. By convention, ``False`` and ``True`` are\n   returned for a successful comparison. However, these methods can\n   return any value, so if the comparison operator is used in a\n   Boolean context (e.g., in the condition of an ``if`` statement),\n   Python will call ``bool()`` on the value to determine if the result\n   is true or false.\n\n   There are no implied relationships among the comparison operators.\n   The truth of ``x==y`` does not imply that ``x!=y`` is false.\n   Accordingly, when defining ``__eq__()``, one should also define\n   ``__ne__()`` so that the operators will behave as expected.  See\n   the paragraph on ``__hash__()`` for some important notes on\n   creating *hashable* objects which support custom comparison\n   operations and are usable as dictionary keys.\n\n   There are no swapped-argument versions of these methods (to be used\n   when the left argument does not support the operation but the right\n   argument does); rather, ``__lt__()`` and ``__gt__()`` are each\n   other\'s reflection, ``__le__()`` and ``__ge__()`` are each other\'s\n   reflection, and ``__eq__()`` and ``__ne__()`` are their own\n   reflection.\n\n   Arguments to rich comparison methods are never coerced.\n\n   To automatically generate ordering operations from a single root\n   operation, see ``functools.total_ordering()``.\n\nobject.__hash__(self)\n\n   Called by built-in function ``hash()`` and for operations on\n   members of hashed collections including ``set``, ``frozenset``, and\n   ``dict``.  ``__hash__()`` should return an integer.  The only\n   required property is that objects which compare equal have the same\n   hash value; it is advised to somehow mix together (e.g. using\n   exclusive or) the hash values for the components of the object that\n   also play a part in comparison of objects.\n\n   If a class does not define an ``__eq__()`` method it should not\n   define a ``__hash__()`` operation either; if it defines\n   ``__eq__()`` but not ``__hash__()``, its instances will not be\n   usable as items in hashable collections.  If a class defines\n   mutable objects and implements an ``__eq__()`` method, it should\n   not implement ``__hash__()``, since the implementation of hashable\n   collections requires that a key\'s hash value is immutable (if the\n   object\'s hash value changes, it will be in the wrong hash bucket).\n\n   User-defined classes have ``__eq__()`` and ``__hash__()`` methods\n   by default; with them, all objects compare unequal (except with\n   themselves) and ``x.__hash__()`` returns ``id(x)``.\n\n   Classes which inherit a ``__hash__()`` method from a parent class\n   but change the meaning of ``__eq__()`` such that the hash value\n   returned is no longer appropriate (e.g. by switching to a value-\n   based concept of equality instead of the default identity based\n   equality) can explicitly flag themselves as being unhashable by\n   setting ``__hash__ = None`` in the class definition. Doing so means\n   that not only will instances of the class raise an appropriate\n   ``TypeError`` when a program attempts to retrieve their hash value,\n   but they will also be correctly identified as unhashable when\n   checking ``isinstance(obj, collections.Hashable)`` (unlike classes\n   which define their own ``__hash__()`` to explicitly raise\n   ``TypeError``).\n\n   If a class that overrides ``__eq__()`` needs to retain the\n   implementation of ``__hash__()`` from a parent class, the\n   interpreter must be told this explicitly by setting ``__hash__ =\n   <ParentClass>.__hash__``. Otherwise the inheritance of\n   ``__hash__()`` will be blocked, just as if ``__hash__`` had been\n   explicitly set to ``None``.\n\nobject.__bool__(self)\n\n   Called to implement truth value testing and the built-in operation\n   ``bool()``; should return ``False`` or ``True``.  When this method\n   is not defined, ``__len__()`` is called, if it is defined, and the\n   object is considered true if its result is nonzero.  If a class\n   defines neither ``__len__()`` nor ``__bool__()``, all its instances\n   are considered true.\n',
+ 'debugger': '\n``pdb`` --- The Python Debugger\n*******************************\n\nThe module ``pdb`` defines an interactive source code debugger for\nPython programs.  It supports setting (conditional) breakpoints and\nsingle stepping at the source line level, inspection of stack frames,\nsource code listing, and evaluation of arbitrary Python code in the\ncontext of any stack frame.  It also supports post-mortem debugging\nand can be called under program control.\n\nThe debugger is extensible -- it is actually defined as the class\n``Pdb``. This is currently undocumented but easily understood by\nreading the source.  The extension interface uses the modules ``bdb``\nand ``cmd``.\n\nThe debugger\'s prompt is ``(Pdb)``. Typical usage to run a program\nunder control of the debugger is:\n\n   >>> import pdb\n   >>> import mymodule\n   >>> pdb.run(\'mymodule.test()\')\n   > <string>(0)?()\n   (Pdb) continue\n   > <string>(1)?()\n   (Pdb) continue\n   NameError: \'spam\'\n   > <string>(1)?()\n   (Pdb)\n\n``pdb.py`` can also be invoked as a script to debug other scripts.\nFor example:\n\n   python3 -m pdb myscript.py\n\nWhen invoked as a script, pdb will automatically enter post-mortem\ndebugging if the program being debugged exits abnormally.  After post-\nmortem debugging (or after normal exit of the program), pdb will\nrestart the program.  Automatic restarting preserves pdb\'s state (such\nas breakpoints) and in most cases is more useful than quitting the\ndebugger upon program\'s exit.\n\nNew in version 3.2: ``pdb.py`` now accepts a ``-c`` option that\nexecutes commands as if given in a ``.pdbrc`` file, see *Debugger\nCommands*.\n\nThe typical usage to break into the debugger from a running program is\nto insert\n\n   import pdb; pdb.set_trace()\n\nat the location you want to break into the debugger.  You can then\nstep through the code following this statement, and continue running\nwithout the debugger using the ``continue`` command.\n\nThe typical usage to inspect a crashed program is:\n\n   >>> import pdb\n   >>> import mymodule\n   >>> mymodule.test()\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in ?\n     File "./mymodule.py", line 4, in test\n       test2()\n     File "./mymodule.py", line 3, in test2\n       print(spam)\n   NameError: spam\n   >>> pdb.pm()\n   > ./mymodule.py(3)test2()\n   -> print(spam)\n   (Pdb)\n\nThe module defines the following functions; each enters the debugger\nin a slightly different way:\n\npdb.run(statement, globals=None, locals=None)\n\n   Execute the *statement* (given as a string or a code object) under\n   debugger control.  The debugger prompt appears before any code is\n   executed; you can set breakpoints and type ``continue``, or you can\n   step through the statement using ``step`` or ``next`` (all these\n   commands are explained below).  The optional *globals* and *locals*\n   arguments specify the environment in which the code is executed; by\n   default the dictionary of the module ``__main__`` is used.  (See\n   the explanation of the built-in ``exec()`` or ``eval()``\n   functions.)\n\npdb.runeval(expression, globals=None, locals=None)\n\n   Evaluate the *expression* (given as a string or a code object)\n   under debugger control.  When ``runeval()`` returns, it returns the\n   value of the expression.  Otherwise this function is similar to\n   ``run()``.\n\npdb.runcall(function, *args, **kwds)\n\n   Call the *function* (a function or method object, not a string)\n   with the given arguments.  When ``runcall()`` returns, it returns\n   whatever the function call returned.  The debugger prompt appears\n   as soon as the function is entered.\n\npdb.set_trace()\n\n   Enter the debugger at the calling stack frame.  This is useful to\n   hard-code a breakpoint at a given point in a program, even if the\n   code is not otherwise being debugged (e.g. when an assertion\n   fails).\n\npdb.post_mortem(traceback=None)\n\n   Enter post-mortem debugging of the given *traceback* object.  If no\n   *traceback* is given, it uses the one of the exception that is\n   currently being handled (an exception must be being handled if the\n   default is to be used).\n\npdb.pm()\n\n   Enter post-mortem debugging of the traceback found in\n   ``sys.last_traceback``.\n\nThe ``run*`` functions and ``set_trace()`` are aliases for\ninstantiating the ``Pdb`` class and calling the method of the same\nname.  If you want to access further features, you have to do this\nyourself:\n\nclass class pdb.Pdb(completekey=\'tab\', stdin=None, stdout=None, skip=None, nosigint=False)\n\n   ``Pdb`` is the debugger class.\n\n   The *completekey*, *stdin* and *stdout* arguments are passed to the\n   underlying ``cmd.Cmd`` class; see the description there.\n\n   The *skip* argument, if given, must be an iterable of glob-style\n   module name patterns.  The debugger will not step into frames that\n   originate in a module that matches one of these patterns. [1]\n\n   By default, Pdb sets a handler for the SIGINT signal (which is sent\n   when the user presses Ctrl-C on the console) when you give a\n   ``continue`` command. This allows you to break into the debugger\n   again by pressing Ctrl-C.  If you want Pdb not to touch the SIGINT\n   handler, set *nosigint* tot true.\n\n   Example call to enable tracing with *skip*:\n\n      import pdb; pdb.Pdb(skip=[\'django.*\']).set_trace()\n\n   New in version 3.1: The *skip* argument.\n\n   New in version 3.2: The *nosigint* argument.  Previously, a SIGINT\n   handler was never set by Pdb.\n\n   run(statement, globals=None, locals=None)\n   runeval(expression, globals=None, locals=None)\n   runcall(function, *args, **kwds)\n   set_trace()\n\n      See the documentation for the functions explained above.\n\n\nDebugger Commands\n=================\n\nThe commands recognized by the debugger are listed below.  Most\ncommands can be abbreviated to one or two letters as indicated; e.g.\n``h(elp)`` means that either ``h`` or ``help`` can be used to enter\nthe help command (but not ``he`` or ``hel``, nor ``H`` or ``Help`` or\n``HELP``).  Arguments to commands must be separated by whitespace\n(spaces or tabs).  Optional arguments are enclosed in square brackets\n(``[]``) in the command syntax; the square brackets must not be typed.\nAlternatives in the command syntax are separated by a vertical bar\n(``|``).\n\nEntering a blank line repeats the last command entered.  Exception: if\nthe last command was a ``list`` command, the next 11 lines are listed.\n\nCommands that the debugger doesn\'t recognize are assumed to be Python\nstatements and are executed in the context of the program being\ndebugged.  Python statements can also be prefixed with an exclamation\npoint (``!``).  This is a powerful way to inspect the program being\ndebugged; it is even possible to change a variable or call a function.\nWhen an exception occurs in such a statement, the exception name is\nprinted but the debugger\'s state is not changed.\n\nThe debugger supports *aliases*.  Aliases can have parameters which\nallows one a certain level of adaptability to the context under\nexamination.\n\nMultiple commands may be entered on a single line, separated by\n``;;``.  (A single ``;`` is not used as it is the separator for\nmultiple commands in a line that is passed to the Python parser.)  No\nintelligence is applied to separating the commands; the input is split\nat the first ``;;`` pair, even if it is in the middle of a quoted\nstring.\n\nIf a file ``.pdbrc`` exists in the user\'s home directory or in the\ncurrent directory, it is read in and executed as if it had been typed\nat the debugger prompt.  This is particularly useful for aliases.  If\nboth files exist, the one in the home directory is read first and\naliases defined there can be overridden by the local file.\n\nChanged in version 3.2: ``.pdbrc`` can now contain commands that\ncontinue debugging, such as ``continue`` or ``next``.  Previously,\nthese commands had no effect.\n\nh(elp) [command]\n\n   Without argument, print the list of available commands.  With a\n   *command* as argument, print help about that command.  ``help pdb``\n   displays the full documentation (the docstring of the ``pdb``\n   module).  Since the *command* argument must be an identifier,\n   ``help exec`` must be entered to get help on the ``!`` command.\n\nw(here)\n\n   Print a stack trace, with the most recent frame at the bottom.  An\n   arrow indicates the current frame, which determines the context of\n   most commands.\n\nd(own) [count]\n\n   Move the current frame *count* (default one) levels down in the\n   stack trace (to a newer frame).\n\nu(p) [count]\n\n   Move the current frame *count* (default one) levels up in the stack\n   trace (to an older frame).\n\nb(reak) [([filename:]lineno | function) [, condition]]\n\n   With a *lineno* argument, set a break there in the current file.\n   With a *function* argument, set a break at the first executable\n   statement within that function.  The line number may be prefixed\n   with a filename and a colon, to specify a breakpoint in another\n   file (probably one that hasn\'t been loaded yet).  The file is\n   searched on ``sys.path``.  Note that each breakpoint is assigned a\n   number to which all the other breakpoint commands refer.\n\n   If a second argument is present, it is an expression which must\n   evaluate to true before the breakpoint is honored.\n\n   Without argument, list all breaks, including for each breakpoint,\n   the number of times that breakpoint has been hit, the current\n   ignore count, and the associated condition if any.\n\ntbreak [([filename:]lineno | function) [, condition]]\n\n   Temporary breakpoint, which is removed automatically when it is\n   first hit. The arguments are the same as for ``break``.\n\ncl(ear) [filename:lineno | bpnumber [bpnumber ...]]\n\n   With a *filename:lineno* argument, clear all the breakpoints at\n   this line. With a space separated list of breakpoint numbers, clear\n   those breakpoints. Without argument, clear all breaks (but first\n   ask confirmation).\n\ndisable [bpnumber [bpnumber ...]]\n\n   Disable the breakpoints given as a space separated list of\n   breakpoint numbers.  Disabling a breakpoint means it cannot cause\n   the program to stop execution, but unlike clearing a breakpoint, it\n   remains in the list of breakpoints and can be (re-)enabled.\n\nenable [bpnumber [bpnumber ...]]\n\n   Enable the breakpoints specified.\n\nignore bpnumber [count]\n\n   Set the ignore count for the given breakpoint number.  If count is\n   omitted, the ignore count is set to 0.  A breakpoint becomes active\n   when the ignore count is zero.  When non-zero, the count is\n   decremented each time the breakpoint is reached and the breakpoint\n   is not disabled and any associated condition evaluates to true.\n\ncondition bpnumber [condition]\n\n   Set a new *condition* for the breakpoint, an expression which must\n   evaluate to true before the breakpoint is honored.  If *condition*\n   is absent, any existing condition is removed; i.e., the breakpoint\n   is made unconditional.\n\ncommands [bpnumber]\n\n   Specify a list of commands for breakpoint number *bpnumber*.  The\n   commands themselves appear on the following lines.  Type a line\n   containing just ``end`` to terminate the commands. An example:\n\n      (Pdb) commands 1\n      (com) print some_variable\n      (com) end\n      (Pdb)\n\n   To remove all commands from a breakpoint, type commands and follow\n   it immediately with ``end``; that is, give no commands.\n\n   With no *bpnumber* argument, commands refers to the last breakpoint\n   set.\n\n   You can use breakpoint commands to start your program up again.\n   Simply use the continue command, or step, or any other command that\n   resumes execution.\n\n   Specifying any command resuming execution (currently continue,\n   step, next, return, jump, quit and their abbreviations) terminates\n   the command list (as if that command was immediately followed by\n   end). This is because any time you resume execution (even with a\n   simple next or step), you may encounter another breakpoint--which\n   could have its own command list, leading to ambiguities about which\n   list to execute.\n\n   If you use the \'silent\' command in the command list, the usual\n   message about stopping at a breakpoint is not printed.  This may be\n   desirable for breakpoints that are to print a specific message and\n   then continue.  If none of the other commands print anything, you\n   see no sign that the breakpoint was reached.\n\ns(tep)\n\n   Execute the current line, stop at the first possible occasion\n   (either in a function that is called or on the next line in the\n   current function).\n\nn(ext)\n\n   Continue execution until the next line in the current function is\n   reached or it returns.  (The difference between ``next`` and\n   ``step`` is that ``step`` stops inside a called function, while\n   ``next`` executes called functions at (nearly) full speed, only\n   stopping at the next line in the current function.)\n\nunt(il) [lineno]\n\n   Without argument, continue execution until the line with a number\n   greater than the current one is reached.\n\n   With a line number, continue execution until a line with a number\n   greater or equal to that is reached.  In both cases, also stop when\n   the current frame returns.\n\n   Changed in version 3.2: Allow giving an explicit line number.\n\nr(eturn)\n\n   Continue execution until the current function returns.\n\nc(ont(inue))\n\n   Continue execution, only stop when a breakpoint is encountered.\n\nj(ump) lineno\n\n   Set the next line that will be executed.  Only available in the\n   bottom-most frame.  This lets you jump back and execute code again,\n   or jump forward to skip code that you don\'t want to run.\n\n   It should be noted that not all jumps are allowed -- for instance\n   it is not possible to jump into the middle of a ``for`` loop or out\n   of a ``finally`` clause.\n\nl(ist) [first[, last]]\n\n   List source code for the current file.  Without arguments, list 11\n   lines around the current line or continue the previous listing.\n   With ``.`` as argument, list 11 lines around the current line.\n   With one argument, list 11 lines around at that line.  With two\n   arguments, list the given range; if the second argument is less\n   than the first, it is interpreted as a count.\n\n   The current line in the current frame is indicated by ``->``.  If\n   an exception is being debugged, the line where the exception was\n   originally raised or propagated is indicated by ``>>``, if it\n   differs from the current line.\n\n   New in version 3.2: The ``>>`` marker.\n\nll | longlist\n\n   List all source code for the current function or frame.\n   Interesting lines are marked as for ``list``.\n\n   New in version 3.2.\n\na(rgs)\n\n   Print the argument list of the current function.\n\np(rint) expression\n\n   Evaluate the *expression* in the current context and print its\n   value.\n\npp expression\n\n   Like the ``print`` command, except the value of the expression is\n   pretty-printed using the ``pprint`` module.\n\nwhatis expression\n\n   Print the type of the *expression*.\n\nsource expression\n\n   Try to get source code for the given object and display it.\n\n   New in version 3.2.\n\ndisplay [expression]\n\n   Display the value of the expression if it changed, each time\n   execution stops in the current frame.\n\n   Without expression, list all display expressions for the current\n   frame.\n\n   New in version 3.2.\n\nundisplay [expression]\n\n   Do not display the expression any more in the current frame.\n   Without expression, clear all display expressions for the current\n   frame.\n\n   New in version 3.2.\n\ninteract\n\n   Start an interative interpreter (using the ``code`` module) whose\n   global namespace contains all the (global and local) names found in\n   the current scope.\n\n   New in version 3.2.\n\nalias [name [command]]\n\n   Create an alias called *name* that executes *command*.  The command\n   must *not* be enclosed in quotes.  Replaceable parameters can be\n   indicated by ``%1``, ``%2``, and so on, while ``%*`` is replaced by\n   all the parameters. If no command is given, the current alias for\n   *name* is shown. If no arguments are given, all aliases are listed.\n\n   Aliases may be nested and can contain anything that can be legally\n   typed at the pdb prompt.  Note that internal pdb commands *can* be\n   overridden by aliases.  Such a command is then hidden until the\n   alias is removed.  Aliasing is recursively applied to the first\n   word of the command line; all other words in the line are left\n   alone.\n\n   As an example, here are two useful aliases (especially when placed\n   in the ``.pdbrc`` file):\n\n      # Print instance variables (usage "pi classInst")\n      alias pi for k in %1.__dict__.keys(): print("%1.",k,"=",%1.__dict__[k])\n      # Print instance variables in self\n      alias ps pi self\n\nunalias name\n\n   Delete the specified alias.\n\n! statement\n\n   Execute the (one-line) *statement* in the context of the current\n   stack frame. The exclamation point can be omitted unless the first\n   word of the statement resembles a debugger command.  To set a\n   global variable, you can prefix the assignment command with a\n   ``global`` statement on the same line, e.g.:\n\n      (Pdb) global list_options; list_options = [\'-l\']\n      (Pdb)\n\nrun [args ...]\nrestart [args ...]\n\n   Restart the debugged Python program.  If an argument is supplied,\n   it is split with ``shlex`` and the result is used as the new\n   ``sys.argv``. History, breakpoints, actions and debugger options\n   are preserved. ``restart`` is an alias for ``run``.\n\nq(uit)\n\n   Quit from the debugger.  The program being executed is aborted.\n\n-[ Footnotes ]-\n\n[1] Whether a frame is considered to originate in a certain module is\n    determined by the ``__name__`` in the frame globals.\n',
+ 'del': '\nThe ``del`` statement\n*********************\n\n   del_stmt ::= "del" target_list\n\nDeletion is recursively defined very similar to the way assignment is\ndefined. Rather that spelling it out in full details, here are some\nhints.\n\nDeletion of a target list recursively deletes each target, from left\nto right.\n\nDeletion of a name removes the binding of that name from the local or\nglobal namespace, depending on whether the name occurs in a ``global``\nstatement in the same code block.  If the name is unbound, a\n``NameError`` exception will be raised.\n\nDeletion of attribute references, subscriptions and slicings is passed\nto the primary object involved; deletion of a slicing is in general\nequivalent to assignment of an empty slice of the right type (but even\nthis is determined by the sliced object).\n\nChanged in version 3.2.\n',
  'dict': '\nDictionary displays\n*******************\n\nA dictionary display is a possibly empty series of key/datum pairs\nenclosed in curly braces:\n\n   dict_display       ::= "{" [key_datum_list | dict_comprehension] "}"\n   key_datum_list     ::= key_datum ("," key_datum)* [","]\n   key_datum          ::= expression ":" expression\n   dict_comprehension ::= expression ":" expression comp_for\n\nA dictionary display yields a new dictionary object.\n\nIf a comma-separated sequence of key/datum pairs is given, they are\nevaluated from left to right to define the entries of the dictionary:\neach key object is used as a key into the dictionary to store the\ncorresponding datum.  This means that you can specify the same key\nmultiple times in the key/datum list, and the final dictionary\'s value\nfor that key will be the last one given.\n\nA dict comprehension, in contrast to list and set comprehensions,\nneeds two expressions separated with a colon followed by the usual\n"for" and "if" clauses. When the comprehension is run, the resulting\nkey and value elements are inserted in the new dictionary in the order\nthey are produced.\n\nRestrictions on the types of the key values are listed earlier in\nsection *The standard type hierarchy*.  (To summarize, the key type\nshould be *hashable*, which excludes all mutable objects.)  Clashes\nbetween duplicate keys are not detected; the last datum (textually\nrightmost in the display) stored for a given key value prevails.\n',
  'dynamic-features': '\nInteraction with dynamic features\n*********************************\n\nThere are several cases where Python statements are illegal when used\nin conjunction with nested scopes that contain free variables.\n\nIf a variable is referenced in an enclosing scope, it is illegal to\ndelete the name.  An error will be reported at compile time.\n\nIf the wild card form of import --- ``import *`` --- is used in a\nfunction and the function contains or is a nested block with free\nvariables, the compiler will raise a ``SyntaxError``.\n\nThe ``eval()`` and ``exec()`` functions do not have access to the full\nenvironment for resolving names.  Names may be resolved in the local\nand global namespaces of the caller.  Free variables are not resolved\nin the nearest enclosing namespace, but in the global namespace.

  'exceptions': '\nExceptions\n**********\n\nExceptions are a means of breaking out of the normal flow of control\nof a code block in order to handle errors or other exceptional\nconditions.

- 'execmodel': '\nExecution model\n***************\n\n\nNaming and binding\n==================\n\n*Names* refer to objects.  Names are introduced by name binding\noperations. Each occurrence of a name in the program text refers to\nthe *binding* of that name established in the innermost function block\ncontaining the use.\n\nA *block* is a piece of Python program text that is executed as a\nunit. The following are blocks: a module, a function body, and a class\ndefinition. Each command typed interactively is a block.  A script\nfile (a file given as standard input to the interpreter or specified\non the interpreter command line the first argument) is a code block.\nA script command (a command specified on the interpreter command line\nwith the \'**-c**\' option) is a code block.  The string argument passed\nto the built-in functions ``eval()`` and ``exec()`` is a code block.\n\nA code block is executed in an *execution frame*.  A frame contains\nsome administrative information (used for debugging) and determines\nwhere and how execution continues after the code block\'s execution has\ncompleted.\n\nA *scope* defines the visibility of a name within a block.  If a local\nvariable is defined in a block, its scope includes that block.  If the\ndefinition occurs in a function block, the scope extends to any blocks\ncontained within the defining one, unless a contained block introduces\na different binding for the name.  The scope of names defined in a\nclass block is limited to the class block; it does not extend to the\ncode blocks of methods -- this includes comprehensions and generator\nexpressions since they are implemented using a function scope.  This\nmeans that the following will fail:\n\n   class A:\n       a = 42\n       b = list(a + i for i in range(10))\n\nWhen a name is used in a code block, it is resolved using the nearest\nenclosing scope.  The set of all such scopes visible to a code block\nis called the block\'s *environment*.\n\nIf a name is bound in a block, it is a local variable of that block,\nunless declared as ``nonlocal``.  If a name is bound at the module\nlevel, it is a global variable.  (The variables of the module code\nblock are local and global.)  If a variable is used in a code block\nbut not defined there, it is a *free variable*.\n\nWhen a name is not found at all, a ``NameError`` exception is raised.\nIf the name refers to a local variable that has not been bound, a\n``UnboundLocalError`` exception is raised.  ``UnboundLocalError`` is a\nsubclass of ``NameError``.\n\nThe following constructs bind names: formal parameters to functions,\n``import`` statements, class and function definitions (these bind the\nclass or function name in the defining block), and targets that are\nidentifiers if occurring in an assignment, ``for`` loop header, or\nafter ``as`` in a ``with`` statement or :keyword.`except` clause. The\n``import`` statement of the form ``from ... import *`` binds all names\ndefined in the imported module, except those beginning with an\nunderscore.  This form may only be used at the module level.\n\nA target occurring in a ``del`` statement is also considered bound for\nthis purpose (though the actual semantics are to unbind the name).  It\nis illegal to unbind a name that is referenced by an enclosing scope;\nthe compiler will report a ``SyntaxError``.\n\nEach assignment or import statement occurs within a block defined by a\nclass or function definition or at the module level (the top-level\ncode block).\n\nIf a name binding operation occurs anywhere within a code block, all\nuses of the name within the block are treated as references to the\ncurrent block.  This can lead to errors when a name is used within a\nblock before it is bound.  This rule is subtle.  Python lacks\ndeclarations and allows name binding operations to occur anywhere\nwithin a code block.  The local variables of a code block can be\ndetermined by scanning the entire text of the block for name binding\noperations.\n\nIf the ``global`` statement occurs within a block, all uses of the\nname specified in the statement refer to the binding of that name in\nthe top-level namespace.  Names are resolved in the top-level\nnamespace by searching the global namespace, i.e. the namespace of the\nmodule containing the code block, and the builtin namespace, the\nnamespace of the module ``builtins``.  The global namespace is\nsearched first.  If the name is not found there, the builtin namespace\nis searched.  The global statement must precede all uses of the name.\n\nThe built-in namespace associated with the execution of a code block\nis actually found by looking up the name ``__builtins__`` in its\nglobal namespace; this should be a dictionary or a module (in the\nlatter case the module\'s dictionary is used).  By default, when in the\n``__main__`` module, ``__builtins__`` is the built-in module\n``builtins``; when in any other module, ``__builtins__`` is an alias\nfor the dictionary of the ``builtins`` module itself.\n``__builtins__`` can be set to a user-created dictionary to create a\nweak form of restricted execution.\n\nNote: Users should not touch ``__builtins__``; it is strictly an\n  implementation detail.  Users wanting to override values in the\n  built-in namespace should ``import`` the ``builtins`` module and\n  modify its attributes appropriately.\n\nThe namespace for a module is automatically created the first time a\nmodule is imported.  The main module for a script is always called\n``__main__``.\n\nThe global statement has the same scope as a name binding operation in\nthe same block.  If the nearest enclosing scope for a free variable\ncontains a global statement, the free variable is treated as a global.\n\nA class definition is an executable statement that may use and define\nnames. These references follow the normal rules for name resolution.\nThe namespace of the class definition becomes the attribute dictionary\nof the class.  Names defined at the class scope are not visible in\nmethods.\n\n\nInteraction with dynamic features\n---------------------------------\n\nThere are several cases where Python statements are illegal when used\nin conjunction with nested scopes that contain free variables.\n\nIf a variable is referenced in an enclosing scope, it is illegal to\ndelete the name.  An error will be reported at compile time.\n\nIf the wild card form of import --- ``import *`` --- is used in a\nfunction and the function contains or is a nested block with free\nvariables, the compiler will raise a ``SyntaxError``.\n\nThe ``eval()`` and ``exec()`` functions do not have access to the full\nenvironment for resolving names.  Names may be resolved in the local\nand global namespaces of the caller.  Free variables are not resolved\nin the nearest enclosing namespace, but in the global namespace.  [1]\nThe ``exec()`` and ``eval()`` functions have optional arguments to\noverride the global and local namespace.  If only one namespace is\nspecified, it is used for both.\n\n\nExceptions\n==========\n\nExceptions are a means of breaking out of the normal flow of control\nof a code block in order to handle errors or other exceptional\nconditions.  An exception is *raised* at the point where the error is\ndetected; it may be *handled* by the surrounding code block or by any\ncode block that directly or indirectly invoked the code block where\nthe error occurred.\n\nThe Python interpreter raises an exception when it detects a run-time\nerror (such as division by zero).

  'exprlists': '\nExpression lists\n****************\n\n   expression_list ::= expression ( "," expression )* [","]\n\nAn expression list containing at least one comma yields a tuple.

A single expression\nwithout a trailing comma doesn\'t create a tuple, but rather yields the\nvalue of that expression. (To create an empty tuple, use an empty pair\nof parentheses: ``()``.)\n',
  'floating': '\nFloating point literals\n***********************\n\nFloating point literals are described by the following lexical\ndefinitions:\n\n   floatnumber   ::= pointfloat | exponentfloat\n   pointfloat    ::= [intpart] fraction | intpart "."\n   exponentfloat ::= (intpart | pointfloat) exponent\n   intpart       ::= digit+\n   fraction      ::= "." digit+\n   exponent      ::= ("e" | "E") ["+" | "-"] digit+\n\nNote that the integer and exponent parts are always interpreted using\nradix 10. For example, ``077e010`` is legal, and denotes the same\nnumber as ``77e10``. The allowed range of floating point literals is\nimplementation-dependent. Some examples of floating point literals:\n\n   3.14    10.    .001    1e100    3.14e-10    0e0\n\nNote that numeric literals do not include a sign; a phrase like ``-1``\nis actually an expression composed of the unary operator ``-`` and the\nliteral ``1``.\n',
  'for': '\nThe ``for`` statement\n*********************\n\nThe ``for`` statement is used to iterate over the elements of a\nsequence (such as a string, tuple or list) or other iterable object:\n\n   for_stmt ::= "for" target_list "in" expression_list ":" suite\n                ["else" ":" suite]\n\nThe expression list is evaluated once; it should yield an iterable\nobject.  An iterator is created for the result of the\n``expression_list``.  The suite is then executed once for each item\nprovided by the iterator, in the order of ascending indices.  Each\nitem in turn is assigned to the target list using the standard rules\nfor assignments (see *Assignment statements*), and then the suite is\nexecuted.  When the items are exhausted (which is immediately when the\nsequence is empty or an iterator raises a ``StopIteration``\nexception), the suite in the ``else`` clause, if present, is executed,\nand the loop terminates.\n\nA ``break`` statement executed in the first suite terminates the loop\nwithout executing the ``else`` clause\'s suite.  A ``continue``\nstatement executed in the first suite skips the rest of the suite and\ncontinues with the next item, or with the ``else`` clause if there was\nno next item.\n\nThe suite may assign to the variable(s) in the target list; this does\nnot affect the next item assigned to it.\n\nNames in the target list are not deleted when the loop is finished,\nbut if the sequence is empty, it will not have been assigned to at all\nby the loop.  Hint: the built-in function ``range()`` returns an\niterator of integers suitable to emulate the effect of Pascal\'s ``for\ni := a to b do``; e.g., ``list(range(3))`` returns the list ``[0, 1,\n2]``.\n\nNote: There is a subtlety when the sequence is being modified by the loop\n  (this can only occur for mutable sequences, i.e. lists).  An\n  internal counter is used to keep track of which item is used next,\n  and this is incremented on each iteration.  When this counter has\n  reached the length of the sequence the loop terminates.  This means\n  that if the suite deletes the current (or a previous) item from the\n  sequence, the next item will be skipped (since it gets the index of\n  the current item which has already been treated).  Likewise, if the\n  suite inserts an item in the sequence before the current item, the\n  current item will be treated again the next time through the loop.\n  This can lead to nasty bugs that can be avoided by making a\n  temporary copy using a slice of the whole sequence, e.g.,\n\n     for x in a[:]:\n         if x < 0: a.remove(x)\n',
- 'formatstrings': '\nFormat String Syntax\n********************\n\nThe ``str.format()`` method and the ``Formatter`` class share the same\nsyntax for format strings (although in the case of ``Formatter``,\nsubclasses can define their own format string syntax.)\n\nFormat strings contain "replacement fields" surrounded by curly braces\n``{}``. Anything that is not contained in braces is considered literal\ntext, which is copied unchanged to the output.  If you need to include\na brace character in the literal text, it can be escaped by doubling:\n``{{`` and ``}}``.\n\nThe grammar for a replacement field is as follows:\n\n      replacement_field ::= "{" field_name ["!" conversion] [":" format_spec] "}"\n      field_name        ::= arg_name ("." attribute_name | "[" element_index "]")*\n      arg_name          ::= (identifier | integer)?\n      attribute_name    ::= identifier\n      element_index     ::= integer\n      conversion        ::= "r" | "s" | "a"\n      format_spec       ::= <described in the next section>\n\nIn less formal terms, the replacement field starts with a *field_name*\nthat specifies the object whose value is to be formatted and inserted\ninto the output instead of the replacement field. The *field_name* is\noptionally followed by a  *conversion* field, which is preceded by an\nexclamation point ``\'!\'``, and a *format_spec*, which is preceded by a\ncolon ``\':\'``.  These specify a non-default format for the replacement\nvalue.\n\nThe *field_name* itself begins with an *arg_name* that is either\neither a number or a keyword.  If it\'s a number, it refers to a\npositional argument, and if it\'s a keyword, it refers to a named\nkeyword argument.  If the numerical arg_names in a format string are\n0, 1, 2, ... in sequence, they can all be omitted (not just some) and\nthe numbers 0, 1, 2, ... will be automatically inserted in that order.\nThe *arg_name* can be followed by any number of index or attribute\nexpressions. An expression of the form ``\'.name\'`` selects the named\nattribute using ``getattr()``, while an expression of the form\n``\'[index]\'`` does an index lookup using ``__getitem__()``.\n\nSome simple format string examples:\n\n   "First, thou shalt count to {0}" # References first positional argument\n   "Bring me a {}"                  # Implicitly references the first positional argument\n   "From {} to {}"                  # Same as "From {0] to {1}"\n   "My quest is {name}"             # References keyword argument \'name\'\n   "Weight in tons {0.weight}"      # \'weight\' attribute of first positional arg\n   "Units destroyed: {players[0]}"  # First element of keyword argument \'players\'.\n\nThe *conversion* field causes a type coercion before formatting.\nNormally, the job of formatting a value is done by the\n``__format__()`` method of the value itself.  However, in some cases\nit is desirable to force a type to be formatted as a string,\noverriding its own definition of formatting.  By converting the value\nto a string before calling ``__format__()``, the normal formatting\nlogic is bypassed.\n\nThree conversion flags are currently supported: ``\'!s\'`` which calls\n``str()`` on the value, ``\'!r\'`` which calls ``repr()`` and ``\'!a\'``\nwhich calls ``ascii()``.\n\nSome examples:\n\n   "Harold\'s a clever {0!s}"        # Calls str() on the argument first\n   "Bring out the holy {name!r}"    # Calls repr() on the argument first\n\nThe *format_spec* field contains a specification of how the value\nshould be presented, including such details as field width, alignment,\npadding, decimal precision and so on.  Each value type can define it\'s\nown "formatting mini-language" or interpretation of the *format_spec*.\n\nMost built-in types support a common formatting mini-language, which\nis described in the next section.\n\nA *format_spec* field can also include nested replacement fields\nwithin it. These nested replacement fields can contain only a field\nname; conversion flags and format specifications are not allowed.  The\nreplacement fields within the format_spec are substituted before the\n*format_spec* string is interpreted. This allows the formatting of a\nvalue to be dynamically specified.\n\nFor example, suppose you wanted to have a replacement field whose\nfield width is determined by another variable:\n\n   "A man with two {0:{1}}".format("noses", 10)\n\nThis would first evaluate the inner replacement field, making the\nformat string effectively:\n\n   "A man with two {0:10}"\n\nThen the outer replacement field would be evaluated, producing:\n\n   "noses     "\n\nWhich is substituted into the string, yielding:\n\n   "A man with two noses     "\n\n(The extra space is because we specified a field width of 10, and\nbecause left alignment is the default for strings.)\n\n\nFormat Specification Mini-Language\n==================================\n\n"Format specifications" are used within replacement fields contained\nwithin a format string to define how individual values are presented\n(see *Format String Syntax*.)  They can also be passed directly to the\nbuiltin ``format()`` function.  Each formattable type may define how\nthe format specification is to be interpreted.\n\nMost built-in types implement the following options for format\nspecifications, although some of the formatting options are only\nsupported by the numeric types.\n\nA general convention is that an empty format string (``""``) produces\nthe same result as if you had called ``str()`` on the value.\n\nThe general form of a *standard format specifier* is:\n\n   format_spec ::= [[fill]align][sign][#][0][width][.precision][type]\n   fill        ::= <a character other than \'}\'>\n   align       ::= "<" | ">" | "=" | "^"\n   sign        ::= "+" | "-" | " "\n   width       ::= integer\n   precision   ::= integer\n   type        ::= "b" | "c" | "d" | "e" | "E" | "f" | "F" | "g" | "G" | "n" | "o" | "x" | "X" | "%"\n\nThe *fill* character can be any character other than \'}\' (which\nsignifies the end of the field).  The presence of a fill character is\nsignaled by the *next* character, which must be one of the alignment\noptions. If the second character of *format_spec* is not a valid\nalignment option, then it is assumed that both the fill character and\nthe alignment option are absent.\n\nThe meaning of the various alignment options is as follows:\n\n   +-----------+------------------------------------------------------------+\n   | Option    | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'<\'``   | Forces the field to be left-aligned within the available   |\n   |           | space (This is the default.)                               |\n   +-----------+------------------------------------------------------------+\n   | ``\'>\'``   | Forces the field to be right-aligned within the available  |\n   |           | space.                                                     |\n   +-----------+------------------------------------------------------------+\n   | ``\'=\'``   | Forces the padding to be placed after the sign (if any)    |\n   |           | but before the digits.  This is used for printing fields   |\n   |           | in the form \'+000000120\'. This alignment option is only    |\n   |           | valid for numeric types.                                   |\n   +-----------+------------------------------------------------------------+\n   | ``\'^\'``   | Forces the field to be centered within the available       |\n   |           | space.                                                     |\n   +-----------+------------------------------------------------------------+\n\nNote that unless a minimum field width is defined, the field width\nwill always be the same size as the data to fill it, so that the\nalignment option has no meaning in this case.\n\nThe *sign* option is only valid for number types, and can be one of\nthe following:\n\n   +-----------+------------------------------------------------------------+\n   | Option    | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'+\'``   | indicates that a sign should be used for both positive as  |\n   |           | well as negative numbers.                                  |\n   +-----------+------------------------------------------------------------+\n   | ``\'-\'``   | indicates that a sign should be used only for negative     |\n   |           | numbers (this is the default behavior).                    |\n   +-----------+------------------------------------------------------------+\n   | space     | indicates that a leading space should be used on positive  |\n   |           | numbers, and a minus sign on negative numbers.             |\n   +-----------+------------------------------------------------------------+\n\nThe ``\'#\'`` option is only valid for integers, and only for binary,\noctal, or hexadecimal output.  If present, it specifies that the\noutput will be prefixed by ``\'0b\'``, ``\'0o\'``, or ``\'0x\'``,\nrespectively.\n\n*width* is a decimal integer defining the minimum field width.  If not\nspecified, then the field width will be determined by the content.\n\nIf the *width* field is preceded by a zero (``\'0\'``) character, this\nenables zero-padding.  This is equivalent to an *alignment* type of\n``\'=\'`` and a *fill* character of ``\'0\'``.\n\nThe *precision* is a decimal number indicating how many digits should\nbe displayed after the decimal point for a floating point value\nformatted with ``\'f\'`` and ``\'F\'``, or before and after the decimal\npoint for a floating point value formatted with ``\'g\'`` or ``\'G\'``.\nFor non-number types the field indicates the maximum field size - in\nother words, how many characters will be used from the field content.\nThe *precision* is not allowed for integer values.\n\nFinally, the *type* determines how the data should be presented.\n\nThe available integer presentation types are:\n\n   +-----------+------------------------------------------------------------+\n   | Type      | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'b\'``   | Binary format.

+ 'formatstrings': '\nFormat String Syntax\n********************\n\nThe ``str.format()`` method and the ``Formatter`` class share the same\nsyntax for format strings (although in the case of ``Formatter``,\nsubclasses can define their own format string syntax).\n\nFormat strings contain "replacement fields" surrounded by curly braces\n``{}``. Anything that is not contained in braces is considered literal\ntext, which is copied unchanged to the output.  If you need to include\na brace character in the literal text, it can be escaped by doubling:\n``{{`` and ``}}``.\n\nThe grammar for a replacement field is as follows:\n\n      replacement_field ::= "{" [field_name] ["!" conversion] [":" format_spec] "}"\n      field_name        ::= arg_name ("." attribute_name | "[" element_index "]")*\n      arg_name          ::= [identifier | integer]\n      attribute_name    ::= identifier\n      element_index     ::= integer | index_string\n      index_string      ::= <any source character except "]"> +\n      conversion        ::= "r" | "s" | "a"\n      format_spec       ::= <described in the next section>\n\nIn less formal terms, the replacement field can start with a\n*field_name* that specifies the object whose value is to be formatted\nand inserted into the output instead of the replacement field. The\n*field_name* is optionally followed by a  *conversion* field, which is\npreceded by an exclamation point ``\'!\'``, and a *format_spec*, which\nis preceded by a colon ``\':\'``.  These specify a non-default format\nfor the replacement value.\n\nSee also the *Format Specification Mini-Language* section.\n\nThe *field_name* itself begins with an *arg_name* that is either\neither a number or a keyword.  If it\'s a number, it refers to a\npositional argument, and if it\'s a keyword, it refers to a named\nkeyword argument.  If the numerical arg_names in a format string are\n0, 1, 2, ... in sequence, they can all be omitted (not just some) and\nthe numbers 0, 1, 2, ... will be automatically inserted in that order.\nThe *arg_name* can be followed by any number of index or attribute\nexpressions. An expression of the form ``\'.name\'`` selects the named\nattribute using ``getattr()``, while an expression of the form\n``\'[index]\'`` does an index lookup using ``__getitem__()``.\n\nChanged in version 3.1: The positional argument specifiers can be\nomitted, so ``\'{} {}\'`` is equivalent to ``\'{0} {1}\'``.\n\nSome simple format string examples:\n\n   "First, thou shalt count to {0}" # References first positional argument\n   "Bring me a {}"                  # Implicitly references the first positional argument\n   "From {} to {}"                  # Same as "From {0} to {1}"\n   "My quest is {name}"             # References keyword argument \'name\'\n   "Weight in tons {0.weight}"      # \'weight\' attribute of first positional arg\n   "Units destroyed: {players[0]}"  # First element of keyword argument \'players\'.\n\nThe *conversion* field causes a type coercion before formatting.\nNormally, the job of formatting a value is done by the\n``__format__()`` method of the value itself.  However, in some cases\nit is desirable to force a type to be formatted as a string,\noverriding its own definition of formatting.  By converting the value\nto a string before calling ``__format__()``, the normal formatting\nlogic is bypassed.\n\nThree conversion flags are currently supported: ``\'!s\'`` which calls\n``str()`` on the value, ``\'!r\'`` which calls ``repr()`` and ``\'!a\'``\nwhich calls ``ascii()``.\n\nSome examples:\n\n   "Harold\'s a clever {0!s}"        # Calls str() on the argument first\n   "Bring out the holy {name!r}"    # Calls repr() on the argument first\n   "More {!a}"                      # Calls ascii() on the argument first\n\nThe *format_spec* field contains a specification of how the value\nshould be presented, including such details as field width, alignment,\npadding, decimal precision and so on.  Each value type can define its\nown "formatting mini-language" or interpretation of the *format_spec*.\n\nMost built-in types support a common formatting mini-language, which\nis described in the next section.\n\nA *format_spec* field can also include nested replacement fields\nwithin it. These nested replacement fields can contain only a field\nname; conversion flags and format specifications are not allowed.  The\nreplacement fields within the format_spec are substituted before the\n*format_spec* string is interpreted. This allows the formatting of a\nvalue to be dynamically specified.\n\nSee the *Format examples* section for some examples.\n\n\nFormat Specification Mini-Language\n==================================\n\n"Format specifications" are used within replacement fields contained\nwithin a format string to define how individual values are presented\n(see *Format String Syntax*).  They can also be passed directly to the\nbuilt-in ``format()`` function.  Each formattable type may define how\nthe format specification is to be interpreted.\n\nMost built-in types implement the following options for format\nspecifications, although some of the formatting options are only\nsupported by the numeric types.\n\nA general convention is that an empty format string (``""``) produces\nthe same result as if you had called ``str()`` on the value. A non-\nempty format string typically modifies the result.\n\nThe general form of a *standard format specifier* is:\n\n   format_spec ::= [[fill]align][sign][#][0][width][,][.precision][type]\n   fill        ::= <a character other than \'}\'>\n   align       ::= "<" | ">" | "=" | "^"\n   sign        ::= "+" | "-" | " "\n   width       ::= integer\n   precision   ::= integer\n   type        ::= "b" | "c" | "d" | "e" | "E" | "f" | "F" | "g" | "G" | "n" | "o" | "s" | "x" | "X" | "%"\n\nThe *fill* character can be any character other than \'{\' or \'}\'.  The\npresence of a fill character is signaled by the character following\nit, which must be one of the alignment options.  If the second\ncharacter of *format_spec* is not a valid alignment option, then it is\nassumed that both the fill character and the alignment option are\nabsent.\n\nThe meaning of the various alignment options is as follows:\n\n   +-----------+------------------------------------------------------------+\n   | Option    | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'<\'``   | Forces the field to be left-aligned within the available   |\n   |           | space (this is the default for most objects).              |\n   +-----------+------------------------------------------------------------+\n   | ``\'>\'``   | Forces the field to be right-aligned within the available  |\n   |           | space (this is the default for numbers).                   |\n   +-----------+------------------------------------------------------------+\n   | ``\'=\'``   | Forces the padding to be placed after the sign (if any)    |\n   |           | but before the digits.  This is used for printing fields   |\n   |           | in the form \'+000000120\'. This alignment option is only    |\n   |           | valid for numeric types.                                   |\n   +-----------+------------------------------------------------------------+\n   | ``\'^\'``   | Forces the field to be centered within the available       |\n   |           | space.                                                     |\n   +-----------+------------------------------------------------------------+\n\nNote that unless a minimum field width is defined, the field width\nwill always be the same size as the data to fill it, so that the\nalignment option has no meaning in this case.\n\nThe *sign* option is only valid for number types, and can be one of\nthe following:\n\n   +-----------+------------------------------------------------------------+\n   | Option    | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'+\'``   | indicates that a sign should be used for both positive as  |\n   |           | well as negative numbers.                                  |\n   +-----------+------------------------------------------------------------+\n   | ``\'-\'``   | indicates that a sign should be used only for negative     |\n   |           | numbers (this is the default behavior).                    |\n   +-----------+------------------------------------------------------------+\n   | space     | indicates that a leading space should be used on positive  |\n   |           | numbers, and a minus sign on negative numbers.             |\n   +-----------+------------------------------------------------------------+\n\nThe ``\'#\'`` option causes the "alternate form" to be used for the\nconversion.  The alternate form is defined differently for different\ntypes.  This option is only valid for integer, float, complex and\nDecimal types. For integers, when binary, octal, or hexadecimal output\nis used, this option adds the prefix respective ``\'0b\'``, ``\'0o\'``, or\n``\'0x\'`` to the output value. For floats, complex and Decimal the\nalternate form causes the result of the conversion to always contain a\ndecimal-point character, even if no digits follow it. Normally, a\ndecimal-point character appears in the result of these conversions\nonly if a digit follows it. In addition, for ``\'g\'`` and ``\'G\'``\nconversions, trailing zeros are not removed from the result.\n\nThe ``\',\'`` option signals the use of a comma for a thousands\nseparator. For a locale aware separator, use the ``\'n\'`` integer\npresentation type instead.\n\nChanged in version 3.1: Added the ``\',\'`` option (see also **PEP\n378**).\n\n*width* is a decimal integer defining the minimum field width.  If not\nspecified, then the field width will be determined by the content.\n\nIf the *width* field is preceded by a zero (``\'0\'``) character, this\nenables zero-padding.  This is equivalent to an *alignment* type of\n``\'=\'`` and a *fill* character of ``\'0\'``.\n\nThe *precision* is a decimal number indicating how many digits should\nbe displayed after the decimal point for a floating point value\nformatted with ``\'f\'`` and ``\'F\'``, or before and after the decimal\npoint for a floating point value formatted with ``\'g\'`` or ``\'G\'``.\nFor non-number types the field indicates the maximum field size - in\nother words, how many characters will be used from the field content.\nThe *precision* is not allowed for integer values.\n\nFinally, the *type* determines how the data should be presented.\n\nThe available string presentation types are:\n\n   +-----------+------------------------------------------------------------+\n   | Type      | Meaning                                                    |\n   +===========+============================================================+\n   | ``\'s\'``   | String format.

Same as ``\'f\'``, but converts ``nan`` to      |\n   |           | ``NAN`` and ``inf`` to ``INF``.                            |\n   +-----------+------------------------------------------------------------+\n   | ``\'g\'``   | General format.  For a given precision ``p >= 1``, this    |\n   |           | rounds the number to ``p`` significant digits and then     |\n   |           | formats the result in either fixed-point format or in      |\n   |           | scientific notation, depending on its magnitude.  The      |\n   |           | precise rules are as follows: suppose that the result      |\n   |           | formatted with presentation type ``\'e\'`` and precision     |\n   |           | ``p-1`` would have exponent ``exp``.  Then if ``-4 <= exp  |\n   |           | < p``, the number is formatted with presentation type      |\n   |           | ``\'f\'`` and precision ``p-1-exp``. Otherwise, the number   |\n   |           | is formatted with presentation type ``\'e\'`` and precision  |\n   |           | ``p-1``. In both cases insignificant trailing zeros are    |\n   |           | removed from the significand, and the decimal point is     |\n   |           | also removed if there are no remaining digits following    |\n   |           | it.  Positive and negative infinity, positive and negative |\n   |           | zero, and nans, are formatted as ``inf``, ``-inf``, ``0``, |\n   |           | ``-0`` and ``nan`` respectively, regardless of the         |\n   |           | precision.  A precision of ``0`` is treated as equivalent  |\n   |           | to a precision of ``1``.                                   |\n   +-----------+------------------------------------------------------------+\n   | ``\'G\'``   | General format. Same as ``\'g\'`` except switches to ``\'E\'`` |\n   |           | if the number gets too large. The representations of       |\n   |           | infinity and NaN are uppercased, too.                      |\n   +-----------+------------------------------------------------------------+\n   | ``\'n\'``   | Number. This is the same as ``\'g\'``, except that it uses   |\n   |           | the current locale setting to insert the appropriate       |\n   |           | number separator characters.                               |\n   +-----------+------------------------------------------------------------+\n   | ``\'%\'``   | Percentage.

  'function': '\nFunction definitions\n********************\n\nA function definition defines a user-defined function object (see\nsection *The standard type hierarchy*):\n\n   funcdef        ::= [decorators] "def" funcname "(" [parameter_list] ")" ["->" expression] ":" suite\n   decorators     ::= decorator+\n   decorator      ::= "@" dotted_name ["(" [argument_list [","]] ")"] NEWLINE\n   dotted_name    ::= identifier ("." identifier)*\n   parameter_list ::= (defparameter ",")*\n                      (  "*" [parameter] ("," defparameter)*\n                      [, "**" parameter]\n                      | "**" parameter\n                      | defparameter [","] )\n   parameter      ::= identifier [":" expression]\n   defparameter   ::= parameter ["=" expression]\n   funcname       ::= identifier\n\nA function definition is an executable statement.  Its execution binds\nthe function name in the current local namespace to a function object\n(a wrapper around the executable code for the function).  This\nfunction object contains a reference to the current global namespace\nas the global namespace to be used when the function is called.\n\nThe function definition does not execute the function body; this gets\nexecuted only when the function is called. [3]\n\nA function definition may be wrapped by one or more *decorator*\nexpressions. Decorator expressions are evaluated when the function is\ndefined, in the scope that contains the function definition.  The\nresult must be a callable, which is invoked with the function object\nas the only argument. The returned value is bound to the function name\ninstead of the function object.  Multiple decorators are applied in\nnested fashion. For example, the following code\n\n   @f1(arg)\n   @f2\n   def func(): pass\n\nis equivalent to\n\n   def func(): pass\n   func = f1(arg)(f2(func))\n\nWhen one or more parameters have the form *parameter* ``=``\n*expression*, the function is said to have "default parameter values."\nFor a parameter with a default value, the corresponding argument may\nbe omitted from a call, in which case the parameter\'s default value is\nsubstituted.  If a parameter has a default value, all following\nparameters up until the "``*``" must also have a default value ---\nthis is a syntactic restriction that is not expressed by the grammar.\n\n**Default parameter values are evaluated when the function definition\nis executed.** This means that the expression is evaluated once, when\nthe function is defined, and that that same "pre-computed" value is\nused for each call.  This is especially important to understand when a\ndefault parameter is a mutable object, such as a list or a dictionary:\nif the function modifies the object (e.g. by appending an item to a\nlist), the default value is in effect modified. This is generally not\nwhat was intended.  A way around this is to use ``None`` as the\ndefault, and explicitly test for it in the body of the function, e.g.:\n\n   def whats_on_the_telly(penguin=None):\n       if penguin is None:\n           penguin = []\n       penguin.append("property of the zoo")\n       return penguin\n\nFunction call semantics are described in more detail in section\n*Calls*. A function call always assigns values to all parameters\nmentioned in the parameter list, either from position arguments, from\nkeyword arguments, or from default values.  If the form\n"``*identifier``" is present, it is initialized to a tuple receiving\nany excess positional parameters, defaulting to the empty tuple.  If\nthe form "``**identifier``" is present, it is initialized to a new\ndictionary receiving any excess keyword arguments, defaulting to a new\nempty dictionary. Parameters after "``*``" or "``*identifier``" are\nkeyword-only parameters and may only be passed used keyword arguments.\n\nParameters may have annotations of the form "``: expression``"\nfollowing the parameter name.  Any parameter may have an annotation\neven those of the form ``*identifier`` or ``**identifier``.  Functions\nmay have "return" annotation of the form "``-> expression``" after the\nparameter list.  These annotations can be any valid Python expression\nand are evaluated when the function definition is executed.\nAnnotations may be evaluated in a different order than they appear in\nthe source code.  The presence of annotations does not change the\nsemantics of a function.  The annotation values are available as\nvalues of a dictionary keyed by the parameters\' names in the\n``__annotations__`` attribute of the function object.\n\nIt is also possible to create anonymous functions (functions not bound\nto a name), for immediate use in expressions.  This uses lambda forms,\ndescribed in section *Lambdas*.  Note that the lambda form is merely a\nshorthand for a simplified function definition; a function defined in\na "``def``" statement can be passed around or assigned to another name\njust like a function defined by a lambda form.  The "``def``" form is\nactually more powerful since it allows the execution of multiple\nstatements and annotations.\n\n**Programmer\'s note:** Functions are first-class objects.  A "``def``"\nform executed inside a function definition defines a local function\nthat can be returned or passed around.  Free variables used in the\nnested function can access the local variables of the function\ncontaining the def.  See section *Naming and binding* for details.\n',

Case is significant.\n\n   identifier   ::= xid_start xid_continue*\n   id_start     ::= <all characters in general categories Lu, Ll, Lt, Lm, Lo, Nl, the underscore, and characters with the Other_ID_Start property>\n   id_continue  ::= <all characters in id_start, plus characters in the categories Mn, Mc, Nd, Pc and others with the Other_ID_Continue property>\n   xid_start    ::= <all characters in id_start whose NFKC normalization is in "id_start xid_continue*">\n   xid_continue ::= <all characters in id_continue whose NFKC normalization is in "id_continue*">\n\nThe Unicode category codes mentioned above stand for:\n\n* *Lu* - uppercase letters\n\n* *Ll* - lowercase letters\n\n* *Lt* - titlecase letters\n\n* *Lm* - modifier letters\n\n* *Lo* - other letters\n\n* *Nl* - letter numbers\n\n* *Mn* - nonspacing marks\n\n* *Mc* - spacing combining marks\n\n* *Nd* - decimal numbers\n\n* *Pc* - connector punctuations\n\n* *Other_ID_Start* - explicit list of characters in PropList.txt to\n  support backwards compatibility\n\n* *Other_ID_Continue* - likewise\n\nAll identifiers are converted into the normal form NFKC while parsing;\ncomparison of identifiers is based on NFKC.\n\nA non-normative HTML file listing all valid identifier characters for\nUnicode 4.1 can be found at http://www.dcl.hpi.uni-\npotsdam.de/home/loewis/table-3131.html.\n\n\nKeywords\n========\n\nThe following identifiers are used as reserved words, or *keywords* of\nthe language, and cannot be used as ordinary identifiers.  They must\nbe spelled exactly as written here:\n\n   False      class      finally    is         return\n   None       continue   for        lambda     try\n   True       def        from       nonlocal   while\n   and        del        global     not        with\n   as         elif       if         or         yield\n   assert     else       import     pass\n   break      except     in         raise\n\n\nReserved classes of identifiers\n===============================\n\nCertain classes of identifiers (besides keywords) have special\nmeanings.  These classes are identified by the patterns of leading and\ntrailing underscore characters:\n\n``_*``\n   Not imported by ``from module import *``.  The special identifier\n   ``_`` is used in the interactive interpreter to store the result of\n   the last evaluation; it is stored in the ``builtins`` module.  When\n   not in interactive mode, ``_`` has no special meaning and is not\n   defined. See section *The import statement*.\n\n   Note: The name ``_`` is often used in conjunction with\n     internationalization; refer to the documentation for the\n     ``gettext`` module for more information on this convention.\n\n``__*__``\n   System-defined names. These names are defined by the interpreter\n   and its implementation (including the standard library).  Current\n   system names are discussed in the *Special method names* section\n   and elsewhere.  More will likely be defined in future versions of\n   Python.  *Any* use of ``__*__`` names, in any context, that does\n   not follow explicitly documented use, is subject to breakage\n   without warning.\n\n``__*``\n   Class-private names.  Names in this category, when used within the\n   context of a class definition, are re-written to use a mangled form\n   to help avoid name clashes between "private" attributes of base and\n   derived classes. See section *Identifiers (Names)*.\n',
  'if': '\nThe ``if`` statement\n********************\n\nThe ``if`` statement is used for conditional execution:\n\n   if_stmt ::= "if" expression ":" suite\n               ( "elif" expression ":" suite )*\n               ["else" ":" suite]\n\nIt selects exactly one of the suites by evaluating the expressions one\nby one until one is found to be true (see section *Boolean operations*\nfor the definition of true and false); then that suite is executed\n(and no other part of the ``if`` statement is executed or evaluated).\nIf all expressions are false, the suite of the ``else`` clause, if\npresent, is executed.\n',
  'imaginary': '\nImaginary literals\n******************\n\nImaginary literals are described by the following lexical definitions:\n\n   imagnumber ::= (floatnumber | intpart) ("j" | "J")\n\nAn imaginary literal yields a complex number with a real part of 0.0.\nComplex numbers are represented as a pair of floating point numbers\nand have the same restrictions on their range.  To create a complex\nnumber with a nonzero real part, add a floating point number to it,\ne.g., ``(3+4j)``.  Some examples of imaginary literals:\n\n   3.14j   10.j    10j     .001j   1e100j  3.14e-10j\n',
- 'import': '\nThe ``import`` statement\n************************\n\n   import_stmt     ::= "import" module ["as" name] ( "," module ["as" name] )*\n                   | "from" relative_module "import" identifier ["as" name]\n                   ( "," identifier ["as" name] )*\n                   | "from" relative_module "import" "(" identifier ["as" name]\n                   ( "," identifier ["as" name] )* [","] ")"\n                   | "from" module "import" "*"\n   module          ::= (identifier ".")* identifier\n   relative_module ::= "."* module | "."+\n   name            ::= identifier\n\nImport statements are executed in two steps: (1) find a module, and\ninitialize it if necessary; (2) define a name or names in the local\nnamespace (of the scope where the ``import`` statement occurs). The\nstatement comes in two forms differing on whether it uses the ``from``\nkeyword. The first form (without ``from``) repeats these steps for\neach identifier in the list. The form with ``from`` performs step (1)\nonce, and then performs step (2) repeatedly. For a reference\nimplementation of step (1), see the ``importlib`` module.\n\nTo understand how step (1) occurs, one must first understand how\nPython handles hierarchical naming of modules. To help organize\nmodules and provide a hierarchy in naming, Python has a concept of\npackages. A package can contain other packages and modules while\nmodules cannot contain other modules or packages. From a file system\nperspective, packages are directories and modules are files. The\noriginal specification for packages is still available to read,\nalthough minor details have changed since the writing of that\ndocument.\n\nOnce the name of the module is known (unless otherwise specified, the\nterm "module" will refer to both packages and modules), searching for\nthe module or package can begin. The first place checked is\n``sys.modules``, the cache of all modules that have been imported\npreviously. If the module is found there then it is used in step (2)\nof import.\n\nIf the module is not found in the cache, then ``sys.meta_path`` is\nsearched (the specification for ``sys.meta_path`` can be found in\n**PEP 302**). The object is a list of *finder* objects which are\nqueried in order as to whether they know how to load the module by\ncalling their ``find_module()`` method with the name of the module. If\nthe module happens to be contained within a package (as denoted by the\nexistence of a dot in the name), then a second argument to\n``find_module()`` is given as the value of the ``__path__`` attribute\nfrom the parent package (everything up to the last dot in the name of\nthe module being imported). If a finder can find the module it returns\na *loader* (discussed later) or returns ``None``.\n\nIf none of the finders on ``sys.meta_path`` are able to find the\nmodule then some implicitly defined finders are queried.\nImplementations of Python vary in what implicit meta path finders are\ndefined. The one they all do define, though, is one that handles\n``sys.path_hooks``, ``sys.path_importer_cache``, and ``sys.path``.\n\nThe implicit finder searches for the requested module in the "paths"\nspecified in one of two places ("paths" do not have to be file system\npaths). If the module being imported is supposed to be contained\nwithin a package then the second argument passed to ``find_module()``,\n``__path__`` on the parent package, is used as the source of paths. If\nthe module is not contained in a package then ``sys.path`` is used as\nthe source of paths.\n\nOnce the source of paths is chosen it is iterated over to find a\nfinder that can handle that path. The dict at\n``sys.path_importer_cache`` caches finders for paths and is checked\nfor a finder. If the path does not have a finder cached then\n``sys.path_hooks`` is searched by calling each object in the list with\na single argument of the path, returning a finder or raises\n``ImportError``. If a finder is returned then it is cached in\n``sys.path_importer_cache`` and then used for that path entry. If no\nfinder can be found but the path exists then a value of ``None`` is\nstored in ``sys.path_importer_cache`` to signify that an implicit,\nfile-based finder that handles modules stored as individual files\nshould be used for that path. If the path does not exist then a finder\nwhich always returns ``None`` is placed in the cache for the path.\n\nIf no finder can find the module then ``ImportError`` is raised.\nOtherwise some finder returned a loader whose ``load_module()`` method\nis called with the name of the module to load (see **PEP 302** for the\noriginal definition of loaders). A loader has several responsibilities\nto perform on a module it loads. First, if the module already exists\nin ``sys.modules`` (a possibility if the loader is called outside of\nthe import machinery) then it is to use that module for initialization\nand not a new module. But if the module does not exist in\n``sys.modules`` then it is to be added to that dict before\ninitialization begins. If an error occurs during loading of the module\nand it was added to ``sys.modules`` it is to be removed from the dict.\nIf an error occurs but the module was already in ``sys.modules`` it is\nleft in the dict.\n\nThe loader must set several attributes on the module. ``__name__`` is\nto be set to the name of the module. ``__file__`` is to be the "path"\nto the file unless the module is built-in (and thus listed in\n``sys.builtin_module_names``) in which case the attribute is not set.\nIf what is being imported is a package then ``__path__`` is to be set\nto a list of paths to be searched when looking for modules and\npackages contained within the package being imported. ``__package__``\nis optional but should be set to the name of package that contains the\nmodule or package (the empty string is used for module not contained\nin a package). ``__loader__`` is also optional but should be set to\nthe loader object that is loading the module.\n\nIf an error occurs during loading then the loader raises\n``ImportError`` if some other exception is not already being\npropagated. Otherwise the loader returns the module that was loaded\nand initialized.\n\nWhen step (1) finishes without raising an exception, step (2) can\nbegin.\n\nThe first form of ``import`` statement binds the module name in the\nlocal namespace to the module object, and then goes on to import the\nnext identifier, if any.  If the module name is followed by ``as``,\nthe name following ``as`` is used as the local name for the module.\n\nThe ``from`` form does not bind the module name: it goes through the\nlist of identifiers, looks each one of them up in the module found in\nstep (1), and binds the name in the local namespace to the object thus\nfound.  As with the first form of ``import``, an alternate local name\ncan be supplied by specifying "``as`` localname".  If a name is not\nfound, ``ImportError`` is raised.  If the list of identifiers is\nreplaced by a star (``\'*\'``), all public names defined in the module\nare bound in the local namespace of the ``import`` statement..\n\nThe *public names* defined by a module are determined by checking the\nmodule\'s namespace for a variable named ``__all__``; if defined, it\nmust be a sequence of strings which are names defined or imported by\nthat module.  The names given in ``__all__`` are all considered public\nand are required to exist.  If ``__all__`` is not defined, the set of\npublic names includes all names found in the module\'s namespace which\ndo not begin with an underscore character (``\'_\'``). ``__all__``\nshould contain the entire public API. It is intended to avoid\naccidentally exporting items that are not part of the API (such as\nlibrary modules which were imported and used within the module).\n\nThe ``from`` form with ``*`` may only occur in a module scope.  The\nwild card form of import --- ``import *`` --- is only allowed at the\nmodule level. Attempting to use it in class for function definitions\nwill raise a ``SyntaxError``.\n\nWhen specifying what module to import you do not have to specify the\nabsolute name of the module. When a module or package is contained\nwithin another package it is possible to make a relative import within\nthe same top package without having to mention the package name. By\nusing leading dots in the specified module or package after ``from``\nyou can specify how high to traverse up the current package hierarchy\nwithout specifying exact names. One leading dot means the current\npackage where the module making the import exists. Two dots means up\none package level. Three dots is up two levels, etc. So if you execute\n``from . import mod`` from a module in the ``pkg`` package then you\nwill end up importing ``pkg.mod``. If you execute ``from ..subpkg2\nimprt mod`` from within ``pkg.subpkg1`` you will import\n``pkg.subpkg2.mod``. The specification for relative imports is\ncontained within **PEP 328**.\n\n``importlib.import_module()`` is provided to support applications that\ndetermine which modules need to be loaded dynamically.\n\n\nFuture statements\n=================\n\nA *future statement* is a directive to the compiler that a particular\nmodule should be compiled using syntax or semantics that will be\navailable in a specified future release of Python.  The future\nstatement is intended to ease migration to future versions of Python\nthat introduce incompatible changes to the language.  It allows use of\nthe new features on a per-module basis before the release in which the\nfeature becomes standard.\n\n   future_statement ::= "from" "__future__" "import" feature ["as" name]\n                        ("," feature ["as" name])*\n                        | "from" "__future__" "import" "(" feature ["as" name]\n                        ("," feature ["as" name])* [","] ")"\n   feature          ::= identifier\n   name             ::= identifier\n\nA future statement must appear near the top of the module.  The only\nlines that can appear before a future statement are:\n\n* the module docstring (if any),\n\n* comments,\n\n* blank lines, and\n\n* other future statements.\n\nThe features recognized by Python 3.0 are ``absolute_import``,\n``division``, ``generators``, ``unicode_literals``,\n``print_function``, ``nested_scopes`` and ``with_statement``.  They\nare all redundant because they are always enabled, and only kept for\nbackwards compatibility.\n\nA future statement is recognized and treated specially at compile\ntime: Changes to the semantics of core constructs are often\nimplemented by generating different code.  It may even be the case\nthat a new feature introduces new incompatible syntax (such as a new\nreserved word), in which case the compiler may need to parse the\nmodule differently.  Such decisions cannot be pushed off until\nruntime.\n\nFor any given release, the compiler knows which feature names have\nbeen defined, and raises a compile-time error if a future statement\ncontains a feature not known to it.\n\nThe direct runtime semantics are the same as for any import statement:\nthere is a standard module ``__future__``, described later, and it\nwill be imported in the usual way at the time the future statement is\nexecuted.\n\nThe interesting runtime semantics depend on the specific feature\nenabled by the future statement.\n\nNote that there is nothing special about the statement:\n\n   import __future__ [as name]\n\nThat is not a future statement; it\'s an ordinary import statement with\nno special semantics or syntax restrictions.\n\nCode compiled by calls to the builtin functions ``exec()`` and\n``compile()`` that occur in a module ``M`` containing a future\nstatement will, by default, use the new syntax or semantics associated\nwith the future statement.  This can be controlled by optional\narguments to ``compile()`` --- see the documentation of that function\nfor details.\n\nA future statement typed at an interactive interpreter prompt will\ntake effect for the rest of the interpreter session.  If an\ninterpreter is started with the *-i* option, is passed a script name\nto execute, and the script includes a future statement, it will be in\neffect in the interactive session started after the script is\nexecuted.\n\nSee also:\n\n   **PEP 236** - Back to the __future__\n      The original proposal for the __future__ mechanism.\n',
- 'in': '\nComparisons\n***********\n\nUnlike C, all comparison operations in Python have the same priority,\nwhich is lower than that of any arithmetic, shifting or bitwise\noperation.  Also unlike C, expressions like ``a < b < c`` have the\ninterpretation that is conventional in mathematics:\n\n   comparison    ::= or_expr ( comp_operator or_expr )*\n   comp_operator ::= "<" | ">" | "==" | ">=" | "<=" | "!="\n                     | "is" ["not"] | ["not"] "in"\n\nComparisons yield boolean values: ``True`` or ``False``.\n\nComparisons can be chained arbitrarily, e.g., ``x < y <= z`` is\nequivalent to ``x < y and y <= z``, except that ``y`` is evaluated\nonly once (but in both cases ``z`` is not evaluated at all when ``x <\ny`` is found to be false).\n\nFormally, if *a*, *b*, *c*, ..., *y*, *z* are expressions and *op1*,\n*op2*, ..., *opN* are comparison operators, then ``a op1 b op2 c ... y\nopN z`` is equivalent to ``a op1 b and b op2 c and ... y opN z``,\nexcept that each expression is evaluated at most once.\n\nNote that ``a op1 b op2 c`` doesn\'t imply any kind of comparison\nbetween *a* and *c*, so that, e.g., ``x < y > z`` is perfectly legal\n(though perhaps not pretty).\n\nThe operators ``<``, ``>``, ``==``, ``>=``, ``<=``, and ``!=`` compare\nthe values of two objects.  The objects need not have the same type.\nIf both are numbers, they are converted to a common type.  Otherwise,\nthe ``==`` and ``!=`` operators *always* consider objects of different\ntypes to be unequal, while the ``<``, ``>``, ``>=`` and ``<=``\noperators raise a ``TypeError`` when comparing objects of different\ntypes that do not implement these operators for the given pair of\ntypes.  You can control comparison behavior of objects of non-builtin\ntypes by defining rich comparison methods like ``__gt__()``, described\nin section *Basic customization*.\n\nComparison of objects of the same type depends on the type:\n\n* Numbers are compared arithmetically.\n\n* The values ``float(\'NaN\')`` and ``Decimal(\'NaN\')`` are special. The\n  are identical to themselves, ``x is x`` but are not equal to\n  themselves, ``x != x``.  Additionally, comparing any value to a\n  not-a-number value will return ``False``.  For example, both ``3 <\n  float(\'NaN\')`` and ``float(\'NaN\') < 3`` will return ``False``.\n\n* Bytes objects are compared lexicographically using the numeric\n  values of their elements.\n\n* Strings are compared lexicographically using the numeric equivalents\n  (the result of the built-in function ``ord()``) of their characters.\n  [3] String and bytes object can\'t be compared!\n\n* Tuples and lists are compared lexicographically using comparison of\n  corresponding elements.  This means that to compare equal, each\n  element must compare equal and the two sequences must be of the same\n  type and have the same length.\n\n  If not equal, the sequences are ordered the same as their first\n  differing elements.  For example, ``[1,2,x] <= [1,2,y]`` has the\n  same value as ``x <= y``.  If the corresponding element does not\n  exist, the shorter sequence is ordered first (for example, ``[1,2] <\n  [1,2,3]``).\n\n* Mappings (dictionaries) compare equal if and only if their sorted\n  ``(key, value)`` lists compare equal. [4] Outcomes other than\n  equality are resolved consistently, but are not otherwise defined.\n  [5]\n\n* Sets and frozensets define comparison operators to mean subset and\n  superset tests.  Those relations do not define total orderings (the\n  two sets ``{1,2}`` and {2,3} are not equal, nor subsets of one\n  another, nor supersets of one another).  Accordingly, sets are not\n  appropriate arguments for functions which depend on total ordering.\n  For example, ``min()``, ``max()``, and ``sorted()`` produce\n  undefined results given a list of sets as inputs.\n\n* Most other objects of builtin types compare unequal unless they are\n  the same object; the choice whether one object is considered smaller\n  or larger than another one is made arbitrarily but consistently\n  within one execution of a program.\n\nComparison of objects of the differing types depends on whether either\nof the types provide explicit support for the comparison.  Most\nnumeric types can be compared with one another, but comparisons of\n``float`` and ``Decimal`` are not supported to avoid the inevitable\nconfusion arising from representation issues such as ``float(\'1.1\')``\nbeing inexactly represented and therefore not exactly equal to\n``Decimal(\'1.1\')`` which is.  When cross-type comparison is not\nsupported, the comparison method returns ``NotImplemented``.  This can\ncreate the illusion of non-transitivity between supported cross-type\ncomparisons and unsupported comparisons.  For example, ``Decimal(2) ==\n2`` and *2 == float(2)`* but ``Decimal(2) != float(2)``.\n\nThe operators ``in`` and ``not in`` test for membership.  ``x in s``\nevaluates to true if *x* is a member of *s*, and false otherwise.  ``x\nnot in s`` returns the negation of ``x in s``.  All built-in sequences\nand set types support this as well as dictionary, for which ``in``\ntests whether a the dictionary has a given key. For container types\nsuch as list, tuple, set, frozenset, dict, or collections.deque, the\nexpression ``x in y`` is equivalent to ``any(x is e or x == e for val\ne in y)``.\n\nFor the string and bytes types, ``x in y`` is true if and only if *x*\nis a substring of *y*.  An equivalent test is ``y.find(x) != -1``.\nEmpty strings are always considered to be a substring of any other\nstring, so ``"" in "abc"`` will return ``True``.\n\nFor user-defined classes which define the ``__contains__()`` method,\n``x in y`` is true if and only if ``y.__contains__(x)`` is true.\n\nFor user-defined classes which do not define ``__contains__()`` and do\ndefine ``__getitem__()``, ``x in y`` is true if and only if there is a\nnon-negative integer index *i* such that ``x == y[i]``, and all lower\ninteger indices do not raise ``IndexError`` exception.  (If any other\nexception is raised, it is as if ``in`` raised that exception).\n\nThe operator ``not in`` is defined to have the inverse true value of\n``in``.\n\nThe operators ``is`` and ``is not`` test for object identity: ``x is\ny`` is true if and only if *x* and *y* are the same object.  ``x is\nnot y`` yields the inverse truth value.

If the path does not exist then a finder\nwhich always returns ``None`` is placed in the cache for the path.\n\nIf no finder can find the module then ``ImportError`` is raised.\nOtherwise some finder returned a loader whose ``load_module()`` method\nis called with the name of the module to load (see **PEP 302** for the\noriginal definition of loaders). A loader has several responsibilities\nto perform on a module it loads. First, if the module already exists\nin ``sys.modules`` (a possibility if the loader is called outside of\nthe import machinery) then it is to use that module for initialization\nand not a new module. But if the module does not exist in\n``sys.modules`` then it is to be added to that dict before\ninitialization begins. If an error occurs during loading of the module\nand it was added to ``sys.modules`` it is to be removed from the dict.\nIf an error occurs but the module was already in ``sys.modules`` it is\nleft in the dict.\n\nThe loader must set several attributes on the module. ``__name__`` is\nto be set to the name of the module. ``__file__`` is to be the "path"\nto the file unless the module is built-in (and thus listed in\n``sys.builtin_module_names``) in which case the attribute is not set.\nIf what is being imported is a package then ``__path__`` is to be set\nto a list of paths to be searched when looking for modules and\npackages contained within the package being imported. ``__package__``\nis optional but should be set to the name of package that contains the\nmodule or package (the empty string is used for module not contained\nin a package). ``__loader__`` is also optional but should be set to\nthe loader object that is loading the module.\n\nIf an error occurs during loading then the loader raises\n``ImportError`` if some other exception is not already being\npropagated. Otherwise the loader returns the module that was loaded\nand initialized.\n\nWhen step (1) finishes without raising an exception, step (2) can\nbegin.\n\nThe first form of ``import`` statement binds the module name in the\nlocal namespace to the module object, and then goes on to import the\nnext identifier, if any.  If the module name is followed by ``as``,\nthe name following ``as`` is used as the local name for the module.\n\nThe ``from`` form does not bind the module name: it goes through the\nlist of identifiers, looks each one of them up in the module found in\nstep (1), and binds the name in the local namespace to the object thus\nfound.  As with the first form of ``import``, an alternate local name\ncan be supplied by specifying "``as`` localname".  If a name is not\nfound, ``ImportError`` is raised.  If the list of identifiers is\nreplaced by a star (``\'*\'``), all public names defined in the module\nare bound in the local namespace of the ``import`` statement.\n\nThe *public names* defined by a module are determined by checking the\nmodule\'s namespace for a variable named ``__all__``; if defined, it\nmust be a sequence of strings which are names defined or imported by\nthat module.  The names given in ``__all__`` are all considered public\nand are required to exist.  If ``__all__`` is not defined, the set of\npublic names includes all names found in the module\'s namespace which\ndo not begin with an underscore character (``\'_\'``). ``__all__``\nshould contain the entire public API. It is intended to avoid\naccidentally exporting items that are not part of the API (such as\nlibrary modules which were imported and used within the module).\n\nThe ``from`` form with ``*`` may only occur in a module scope.  The\nwild card form of import --- ``import *`` --- is only allowed at the\nmodule level. Attempting to use it in class or function definitions\nwill raise a ``SyntaxError``.\n\nWhen specifying what module to import you do not have to specify the\nabsolute name of the module. When a module or package is contained\nwithin another package it is possible to make a relative import within\nthe same top package without having to mention the package name. By\nusing leading dots in the specified module or package after ``from``\nyou can specify how high to traverse up the current package hierarchy\nwithout specifying exact names. One leading dot means the current\npackage where the module making the import exists. Two dots means up\none package level. Three dots is up two levels, etc. So if you execute\n``from . import mod`` from a module in the ``pkg`` package then you\nwill end up importing ``pkg.mod``. If you execute ``from ..subpkg2\nimport mod`` from within ``pkg.subpkg1`` you will import\n``pkg.subpkg2.mod``. The specification for relative imports is\ncontained within **PEP 328**.\n\n``importlib.import_module()`` is provided to support applications that\ndetermine which modules need to be loaded dynamically.\n\n\nFuture statements\n=================\n\nA *future statement* is a directive to the compiler that a particular\nmodule should be compiled using syntax or semantics that will be\navailable in a specified future release of Python.  The future\nstatement is intended to ease migration to future versions of Python\nthat introduce incompatible changes to the language.  It allows use of\nthe new features on a per-module basis before the release in which the\nfeature becomes standard.\n\n   future_statement ::= "from" "__future__" "import" feature ["as" name]\n                        ("," feature ["as" name])*\n                        | "from" "__future__" "import" "(" feature ["as" name]\n                        ("," feature ["as" name])* [","] ")"\n   feature          ::= identifier\n   name             ::= identifier\n\nA future statement must appear near the top of the module.  The only\nlines that can appear before a future statement are:\n\n* the module docstring (if any),\n\n* comments,\n\n* blank lines, and\n\n* other future statements.\n\nThe features recognized by Python 3.0 are ``absolute_import``,\n``division``, ``generators``, ``unicode_literals``,\n``print_function``, ``nested_scopes`` and ``with_statement``.  They\nare all redundant because they are always enabled, and only kept for\nbackwards compatibility.\n\nA future statement is recognized and treated specially at compile\ntime: Changes to the semantics of core constructs are often\nimplemented by generating different code.  It may even be the case\nthat a new feature introduces new incompatible syntax (such as a new\nreserved word), in which case the compiler may need to parse the\nmodule differently.  Such decisions cannot be pushed off until\nruntime.\n\nFor any given release, the compiler knows which feature names have\nbeen defined, and raises a compile-time error if a future statement\ncontains a feature not known to it.\n\nThe direct runtime semantics are the same as for any import statement:\nthere is a standard module ``__future__``, described later, and it\nwill be imported in the usual way at the time the future statement is\nexecuted.\n\nThe interesting runtime semantics depend on the specific feature\nenabled by the future statement.\n\nNote that there is nothing special about the statement:\n\n   import __future__ [as name]\n\nThat is not a future statement; it\'s an ordinary import statement with\nno special semantics or syntax restrictions.\n\nCode compiled by calls to the built-in functions ``exec()`` and\n``compile()`` that occur in a module ``M`` containing a future\nstatement will, by default, use the new syntax or semantics associated\nwith the future statement.  This can be controlled by optional\narguments to ``compile()`` --- see the documentation of that function\nfor details.\n\nA future statement typed at an interactive interpreter prompt will\ntake effect for the rest of the interpreter session.  If an\ninterpreter is started with the *-i* option, is passed a script name\nto execute, and the script includes a future statement, it will be in\neffect in the interactive session started after the script is\nexecuted.\n\nSee also:\n\n   **PEP 236** - Back to the __future__\n      The original proposal for the __future__ mechanism.\n',
+ 'in': '\nComparisons\n***********\n\nUnlike C, all comparison operations in Python have the same priority,\nwhich is lower than that of any arithmetic, shifting or bitwise\noperation.  Also unlike C, expressions like ``a < b < c`` have the\ninterpretation that is conventional in mathematics:\n\n   comparison    ::= or_expr ( comp_operator or_expr )*\n   comp_operator ::= "<" | ">" | "==" | ">=" | "<=" | "!="\n                     | "is" ["not"] | ["not"] "in"\n\nComparisons yield boolean values: ``True`` or ``False``.\n\nComparisons can be chained arbitrarily, e.g., ``x < y <= z`` is\nequivalent to ``x < y and y <= z``, except that ``y`` is evaluated\nonly once (but in both cases ``z`` is not evaluated at all when ``x <\ny`` is found to be false).\n\nFormally, if *a*, *b*, *c*, ..., *y*, *z* are expressions and *op1*,\n*op2*, ..., *opN* are comparison operators, then ``a op1 b op2 c ... y\nopN z`` is equivalent to ``a op1 b and b op2 c and ... y opN z``,\nexcept that each expression is evaluated at most once.\n\nNote that ``a op1 b op2 c`` doesn\'t imply any kind of comparison\nbetween *a* and *c*, so that, e.g., ``x < y > z`` is perfectly legal\n(though perhaps not pretty).\n\nThe operators ``<``, ``>``, ``==``, ``>=``, ``<=``, and ``!=`` compare\nthe values of two objects.  The objects need not have the same type.\nIf both are numbers, they are converted to a common type.  Otherwise,\nthe ``==`` and ``!=`` operators *always* consider objects of different\ntypes to be unequal, while the ``<``, ``>``, ``>=`` and ``<=``\noperators raise a ``TypeError`` when comparing objects of different\ntypes that do not implement these operators for the given pair of\ntypes.  You can control comparison behavior of objects of non-built-in\ntypes by defining rich comparison methods like ``__gt__()``, described\nin section *Basic customization*.\n\nComparison of objects of the same type depends on the type:\n\n* Numbers are compared arithmetically.\n\n* The values ``float(\'NaN\')`` and ``Decimal(\'NaN\')`` are special. The\n  are identical to themselves, ``x is x`` but are not equal to\n  themselves, ``x != x``.  Additionally, comparing any value to a\n  not-a-number value will return ``False``.  For example, both ``3 <\n  float(\'NaN\')`` and ``float(\'NaN\') < 3`` will return ``False``.\n\n* Bytes objects are compared lexicographically using the numeric\n  values of their elements.\n\n* Strings are compared lexicographically using the numeric equivalents\n  (the result of the built-in function ``ord()``) of their characters.\n  [3] String and bytes object can\'t be compared!\n\n* Tuples and lists are compared lexicographically using comparison of\n  corresponding elements.  This means that to compare equal, each\n  element must compare equal and the two sequences must be of the same\n  type and have the same length.\n\n  If not equal, the sequences are ordered the same as their first\n  differing elements.  For example, ``[1,2,x] <= [1,2,y]`` has the\n  same value as ``x <= y``.  If the corresponding element does not\n  exist, the shorter sequence is ordered first (for example, ``[1,2] <\n  [1,2,3]``).\n\n* Mappings (dictionaries) compare equal if and only if they have the\n  same ``(key, value)`` pairs. Order comparisons ``(\'<\', \'<=\', \'>=\',\n  \'>\')`` raise ``TypeError``.\n\n* Sets and frozensets define comparison operators to mean subset and\n  superset tests.  Those relations do not define total orderings (the\n  two sets ``{1,2}`` and {2,3} are not equal, nor subsets of one\n  another, nor supersets of one another).  Accordingly, sets are not\n  appropriate arguments for functions which depend on total ordering.\n  For example, ``min()``, ``max()``, and ``sorted()`` produce\n  undefined results given a list of sets as inputs.\n\n* Most other objects of built-in types compare unequal unless they are\n  the same object; the choice whether one object is considered smaller\n  or larger than another one is made arbitrarily but consistently\n  within one execution of a program.\n\nComparison of objects of the differing types depends on whether either\nof the types provide explicit support for the comparison.  Most\nnumeric types can be compared with one another, but comparisons of\n``float`` and ``Decimal`` are not supported to avoid the inevitable\nconfusion arising from representation issues such as ``float(\'1.1\')``\nbeing inexactly represented and therefore not exactly equal to\n``Decimal(\'1.1\')`` which is.  When cross-type comparison is not\nsupported, the comparison method returns ``NotImplemented``.  This can\ncreate the illusion of non-transitivity between supported cross-type\ncomparisons and unsupported comparisons.  For example, ``Decimal(2) ==\n2`` and ``2 == float(2)`` but ``Decimal(2) != float(2)``.\n\nThe operators ``in`` and ``not in`` test for membership.  ``x in s``\nevaluates to true if *x* is a member of *s*, and false otherwise.  ``x\nnot in s`` returns the negation of ``x in s``.  All built-in sequences\nand set types support this as well as dictionary, for which ``in``\ntests whether a the dictionary has a given key. For container types\nsuch as list, tuple, set, frozenset, dict, or collections.deque, the\nexpression ``x in y`` is equivalent to ``any(x is e or x == e for e in\ny)``.\n\nFor the string and bytes types, ``x in y`` is true if and only if *x*\nis a substring of *y*.  An equivalent test is ``y.find(x) != -1``.\nEmpty strings are always considered to be a substring of any other\nstring, so ``"" in "abc"`` will return ``True``.\n\nFor user-defined classes which define the ``__contains__()`` method,\n``x in y`` is true if and only if ``y.__contains__(x)`` is true.\n\nFor user-defined classes which do not define ``__contains__()`` but do\ndefine ``__iter__()``, ``x in y`` is true if some value ``z`` with ``x\n== z`` is produced while iterating over ``y``.  If an exception is\nraised during the iteration, it is as if ``in`` raised that exception.\n\nLastly, the old-style iteration protocol is tried: if a class defines\n``__getitem__()``, ``x in y`` is true if and only if there is a non-\nnegative integer index *i* such that ``x == y[i]``, and all lower\ninteger indices do not raise ``IndexError`` exception.  (If any other\nexception is raised, it is as if ``in`` raised that exception).\n\nThe operator ``not in`` is defined to have the inverse true value of\n``in``.\n\nThe operators ``is`` and ``is not`` test for object identity: ``x is\ny`` is true if and only if *x* and *y* are the same object.  ``x is\nnot y`` yields the inverse truth value.

- 'naming': "\nNaming and binding\n******************\n\n*Names* refer to objects.  Names are introduced by name binding\noperations. Each occurrence of a name in the program text refers to\nthe *binding* of that name established in the innermost function block\ncontaining the use.\n\nA *block* is a piece of Python program text that is executed as a\nunit. The following are blocks: a module, a function body, and a class\ndefinition. Each command typed interactively is a block.  A script\nfile (a file given as standard input to the interpreter or specified\non the interpreter command line the first argument) is a code block.\nA script command (a command specified on the interpreter command line\nwith the '**-c**' option) is a code block.  The string argument passed\nto the built-in functions ``eval()`` and ``exec()`` is a code block.\n\nA code block is executed in an *execution frame*.  A frame contains\nsome administrative information (used for debugging) and determines\nwhere and how execution continues after the code block's execution has\ncompleted.\n\nA *scope* defines the visibility of a name within a block.  If a local\nvariable is defined in a block, its scope includes that block.  If the\ndefinition occurs in a function block, the scope extends to any blocks\ncontained within the defining one, unless a contained block introduces\na different binding for the name.  The scope of names defined in a\nclass block is limited to the class block; it does not extend to the\ncode blocks of methods -- this includes comprehensions and generator\nexpressions since they are implemented using a function scope.  This\nmeans that the following will fail:\n\n   class A:\n       a = 42\n       b = list(a + i for i in range(10))\n\nWhen a name is used in a code block, it is resolved using the nearest\nenclosing scope.

- 'objects': '\nObjects, values and types\n*************************\n\n*Objects* are Python\'s abstraction for data.  All data in a Python\nprogram is represented by objects or by relations between objects. (In\na sense, and in conformance to Von Neumann\'s model of a "stored\nprogram computer," code is also represented by objects.)\n\nEvery object has an identity, a type and a value.  An object\'s\n*identity* never changes once it has been created; you may think of it\nas the object\'s address in memory.  The \'``is``\' operator compares the\nidentity of two objects; the ``id()`` function returns an integer\nrepresenting its identity (currently implemented as its address). An\nobject\'s *type* is also unchangeable. [1] An object\'s type determines\nthe operations that the object supports (e.g., "does it have a\nlength?") and also defines the possible values for objects of that\ntype.  The ``type()`` function returns an object\'s type (which is an\nobject itself).  The *value* of some objects can change.  Objects\nwhose value can change are said to be *mutable*; objects whose value\nis unchangeable once they are created are called *immutable*. (The\nvalue of an immutable container object that contains a reference to a\nmutable object can change when the latter\'s value is changed; however\nthe container is still considered immutable, because the collection of\nobjects it contains cannot be changed.  So, immutability is not\nstrictly the same as having an unchangeable value, it is more subtle.)\nAn object\'s mutability is determined by its type; for instance,\nnumbers, strings and tuples are immutable, while dictionaries and\nlists are mutable.\n\nObjects are never explicitly destroyed; however, when they become\nunreachable they may be garbage-collected.  An implementation is\nallowed to postpone garbage collection or omit it altogether --- it is\na matter of implementation quality how garbage collection is\nimplemented, as long as no objects are collected that are still\nreachable.  (Implementation note: CPython currently uses a reference-\ncounting scheme with (optional) delayed detection of cyclically linked\ngarbage, which collects most objects as soon as they become\nunreachable, but is not guaranteed to collect garbage containing\ncircular references.  See the documentation of the ``gc`` module for\ninformation on controlling the collection of cyclic garbage.  Other\nimplementations act differently and CPython may change.)\n\nNote that the use of the implementation\'s tracing or debugging\nfacilities may keep objects alive that would normally be collectable.\nAlso note that catching an exception with a \'``try``...``except``\'\nstatement may keep objects alive.\n\nSome objects contain references to "external" resources such as open\nfiles or windows.  It is understood that these resources are freed\nwhen the object is garbage-collected, but since garbage collection is\nnot guaranteed to happen, such objects also provide an explicit way to\nrelease the external resource, usually a ``close()`` method. Programs\nare strongly recommended to explicitly close such objects.  The\n\'``try``...``finally``\' statement and the \'``with``\' statement provide\nconvenient ways to do this.\n\nSome objects contain references to other objects; these are called\n*containers*. Examples of containers are tuples, lists and\ndictionaries.  The references are part of a container\'s value.  In\nmost cases, when we talk about the value of a container, we imply the\nvalues, not the identities of the contained objects; however, when we\ntalk about the mutability of a container, only the identities of the\nimmediately contained objects are implied.  So, if an immutable\ncontainer (like a tuple) contains a reference to a mutable object, its\nvalue changes if that mutable object is changed.\n\nTypes affect almost all aspects of object behavior.  Even the\nimportance of object identity is affected in some sense: for immutable\ntypes, operations that compute new values may actually return a\nreference to any existing object with the same type and value, while\nfor mutable objects this is not allowed.  E.g., after ``a = 1; b =\n1``, ``a`` and ``b`` may or may not refer to the same object with the\nvalue one, depending on the implementation, but after ``c = []; d =\n[]``, ``c`` and ``d`` are guaranteed to refer to two different,\nunique, newly created empty lists. (Note that ``c = d = []`` assigns\nthe same object to both ``c`` and ``d``.)\n',

Function\n    ``fmod()`` in the ``math`` module returns a result whose sign\n    matches the sign of the first argument instead, and so returns\n    ``-1e-100`` in this case. Which approach is more appropriate\n    depends on the application.\n\n[2] If x is very close to an exact integer multiple of y, it\'s\n    possible for ``x//y`` to be one larger than ``(x-x%y)//y`` due to\n    rounding.

An even earlier version of\n    Python compared dictionaries by identity only, but this caused\n    surprises because people expected to be able to test a dictionary\n    for emptiness by comparing it to ``{}``.\n\n[6] Due to automatic garbage-collection, free lists, and the dynamic\n    nature of descriptors, you may notice seemingly unusual behaviour\n    in certain uses of the ``is`` operator, like those involving\n    comparisons between instance methods, or constants.

(Note that ``c = d = []`` assigns\nthe same object to both ``c`` and ``d``.)\n',

For example, and\n    assuming a platform on which a Python float is an IEEE 754 double-\n    precision number, in order that ``-1e-100 % 1e100`` have the same\n    sign as ``1e100``, the computed result is ``-1e-100 + 1e100``,\n    which is numerically exactly equal to ``1e100``.  The function\n    ``math.fmod()`` returns a result whose sign matches the sign of\n    the first argument instead, and so returns ``-1e-100`` in this\n    case. Which approach is more appropriate depends on the\n    application.\n\n[2] If x is very close to an exact integer multiple of y, it\'s\n    possible for ``x//y`` to be one larger than ``(x-x%y)//y`` due to\n    rounding.  In such cases, Python returns the latter result, in\n    order to preserve that ``divmod(x,y)[0] * y + x % y`` be very\n    close to ``x``.\n\n[3] While comparisons between strings make sense at the byte level,\n    they may be counter-intuitive to users.  For example, the strings\n    ``"\\u00C7"`` and ``"\\u0327\\u0043"`` compare differently, even\n    though they both represent the same unicode character (LATIN\n    CAPITAL LETTER C WITH CEDILLA).  To compare strings in a human\n    recognizable way, compare using ``unicodedata.normalize()``.\n\n[4] Due to automatic garbage-collection, free lists, and the dynamic\n    nature of descriptors, you may notice seemingly unusual behaviour\n    in certain uses of the ``is`` operator, like those involving\n    comparisons between instance methods, or constants.  Check their\n    documentation for more info.\n\n[5] The ``%`` operator is also used for string formatting; the same\n    precedence applies.\n\n[6] The power operator ``**`` binds less tightly than an arithmetic or\n    bitwise unary operator on its right, that is, ``2**-1`` is\n    ``0.5``.\n',
  'pass': '\nThe ``pass`` statement\n**********************\n\n   pass_stmt ::= "pass"\n\n``pass`` is a null operation --- when it is executed, nothing happens.\nIt is useful as a placeholder when a statement is required\nsyntactically, but no code needs to be executed, for example:\n\n   def f(arg): pass    # a function that does nothing (yet)\n\n   class C: pass       # a class with no methods (yet)\n',
  'power': '\nThe power operator\n******************\n\nThe power operator binds more tightly than unary operators on its\nleft; it binds less tightly than unary operators on its right.  The\nsyntax is:\n\n   power ::= primary ["**" u_expr]\n\nThus, in an unparenthesized sequence of power and unary operators, the\noperators are evaluated from right to left (this does not constrain\nthe evaluation order for the operands): ``-1**2`` results in ``-1``.\n\nThe power operator has the same semantics as the built-in ``pow()``\nfunction, when called with two arguments: it yields its left argument\nraised to the power of its right argument.  The numeric arguments are\nfirst converted to a common type, and the result is of that type.\n\nFor int operands, the result has the same type as the operands unless\nthe second argument is negative; in that case, all arguments are\nconverted to float and a float result is delivered. For example,\n``10**2`` returns ``100``, but ``10**-2`` returns ``0.01``.\n\nRaising ``0.0`` to a negative power results in a\n``ZeroDivisionError``. Raising a negative number to a fractional power\nresults in a ``complex`` number. (In earlier versions it raised a\n``ValueError``.)\n',
  'raise': '\nThe ``raise`` statement\n***********************\n\n   raise_stmt ::= "raise" [expression ["from" expression]]\n\nIf no expressions are present, ``raise`` re-raises the last exception\nthat was active in the current scope.  If no exception is active in\nthe current scope, a ``TypeError`` exception is raised indicating that\nthis is an error (if running under IDLE, a ``queue.Empty`` exception\nis raised instead).\n\nOtherwise, ``raise`` evaluates the first expression as the exception\nobject.  It must be either a subclass or an instance of\n``BaseException``. If it is a class, the exception instance will be\nobtained when needed by instantiating the class with no arguments.\n\nThe *type* of the exception is the exception instance\'s class, the\n*value* is the instance itself.\n\nA traceback object is normally created automatically when an exception\nis raised and attached to it as the ``__traceback__`` attribute, which\nis writable. You can create an exception and set your own traceback in\none step using the ``with_traceback()`` exception method (which\nreturns the same exception instance, with its traceback set to its\nargument), like so:\n\n   raise Exception("foo occurred").with_traceback(tracebackobj)\n\nThe ``from`` clause is used for exception chaining: if given, the\nsecond *expression* must be another exception class or instance, which\nwill then be attached to the raised exception as the ``__cause__``\nattribute (which is writable).  If the raised exception is not\nhandled, both exceptions will be printed:\n\n   >>> try:\n   ...     print(1 / 0)\n   ... except Exception as exc:\n   ...     raise RuntimeError("Something bad happened") from exc\n   ...\n   Traceback (most recent call last):\n     File "<stdin>", line 2, in <module>\n   ZeroDivisionError: int division or modulo by zero\n\n   The above exception was the direct cause of the following exception:\n\n   Traceback (most recent call last):\n     File "<stdin>", line 4, in <module>\n   RuntimeError: Something bad happened\n\nA similar mechanism works implicitly if an exception is raised inside\nan exception handler: the previous exception is then attached as the\nnew exception\'s ``__context__`` attribute:\n\n   >>> try:\n   ...     print(1 / 0)\n   ... except:\n   ...     raise RuntimeError("Something bad happened")\n   ...\n   Traceback (most recent call last):\n     File "<stdin>", line 2, in <module>\n   ZeroDivisionError: int division or modulo by zero\n\n   During handling of the above exception, another exception occurred:\n\n   Traceback (most recent call last):\n     File "<stdin>", line 4, in <module>\n   RuntimeError: Something bad happened\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information about handling exceptions is in section\n*The try statement*.\n',

If the slice list\ncontains at least one comma, the key is a tuple containing the\nconversion of the slice items; otherwise, the conversion of the lone\nslice item is the key.  The conversion of a slice item that is an\nexpression is that expression.  The conversion of a proper slice is a\nslice object (see section *The standard type hierarchy*) whose\n``start``, ``stop`` and ``step`` attributes are the values of the\nexpressions given as lower bound, upper bound and stride,\nrespectively, substituting ``None`` for missing expressions.\n',
- 'specialattrs': "\nSpecial Attributes\n******************\n\nThe implementation adds a few special read-only attributes to several\nobject types, where they are relevant.  Some of these are not reported\nby the ``dir()`` built-in function.\n\nobject.__dict__\n\n   A dictionary or other mapping object used to store an object's\n   (writable) attributes.\n\ninstance.__class__\n\n   The class to which a class instance belongs.\n\nclass.__bases__\n\n   The tuple of base classes of a class object.  If there are no base\n   classes, this will be an empty tuple.\n\nclass.__name__\n\n   The name of the class or type.\n\nThe following attributes are only supported by *new-style class*es.\n\nclass.__mro__\n\n   This attribute is a tuple of classes that are considered when\n   looking for base classes during method resolution.\n\nclass.mro()\n\n   This method can be overridden by a metaclass to customize the\n   method resolution order for its instances.  It is called at class\n   instantiation, and its result is stored in ``__mro__``.\n\nclass.__subclasses__()\n\n   Each new-style class keeps a list of weak references to its\n   immediate subclasses.  This method returns a list of all those\n   references still alive. Example:\n\n      >>> int.__subclasses__()\n      [<type 'bool'>]\n\n-[ Footnotes ]-\n\n[1] Additional information on these special methods may be found in\n    the Python Reference Manual (*Basic customization*).\n\n[2] As a consequence, the list ``[1, 2]`` is considered equal to\n    ``[1.0, 2.0]``, and similarly for tuples.\n\n[3] They must have since the parser can't tell the type of the\n    operands.\n\n[4] To format only a tuple you should therefore provide a singleton\n    tuple whose only element is the tuple to be formatted.\n\n[5] The advantage of leaving the newline on is that returning an empty\n    string is then an unambiguous EOF indication.  It is also possible\n    (in cases where it might matter, for example, if you want to make\n    an exact copy of a file while scanning its lines) to tell whether\n    the last line of a file ended in a newline or not (yes this\n    happens!).\n",
- 'specialnames': '\nSpecial method names\n********************\n\nA class can implement certain operations that are invoked by special\nsyntax (such as arithmetic operations or subscripting and slicing) by\ndefining methods with special names. This is Python\'s approach to\n*operator overloading*, allowing classes to define their own behavior\nwith respect to language operators.  For instance, if a class defines\na method named ``__getitem__()``, and ``x`` is an instance of this\nclass, then ``x[i]`` is roughly equivalent to ``type(x).__getitem__(x,\ni)``.  Except where mentioned, attempts to execute an operation raise\nan exception when no appropriate method is defined (typically\n``AttributeError`` or ``TypeError``).\n\nWhen implementing a class that emulates any built-in type, it is\nimportant that the emulation only be implemented to the degree that it\nmakes sense for the object being modelled.  For example, some\nsequences may work well with retrieval of individual elements, but\nextracting a slice may not make sense.  (One example of this is the\n``NodeList`` interface in the W3C\'s Document Object Model.)\n\n\nBasic customization\n===================\n\nobject.__new__(cls[, ...])\n\n   Called to create a new instance of class *cls*.  ``__new__()`` is a\n   static method (special-cased so you need not declare it as such)\n   that takes the class of which an instance was requested as its\n   first argument.  The remaining arguments are those passed to the\n   object constructor expression (the call to the class).  The return\n   value of ``__new__()`` should be the new object instance (usually\n   an instance of *cls*).\n\n   Typical implementations create a new instance of the class by\n   invoking the superclass\'s ``__new__()`` method using\n   ``super(currentclass, cls).__new__(cls[, ...])`` with appropriate\n   arguments and then modifying the newly-created instance as\n   necessary before returning it.\n\n   If ``__new__()`` returns an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will be invoked like\n   ``__init__(self[, ...])``, where *self* is the new instance and the\n   remaining arguments are the same as were passed to ``__new__()``.\n\n   If ``__new__()`` does not return an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will not be invoked.\n\n   ``__new__()`` is intended mainly to allow subclasses of immutable\n   types (like int, str, or tuple) to customize instance creation.  It\n   is also commonly overridden in custom metaclasses in order to\n   customize class creation.\n\nobject.__init__(self[, ...])\n\n   Called when the instance is created.  The arguments are those\n   passed to the class constructor expression.  If a base class has an\n   ``__init__()`` method, the derived class\'s ``__init__()`` method,\n   if any, must explicitly call it to ensure proper initialization of\n   the base class part of the instance; for example:\n   ``BaseClass.__init__(self, [args...])``.  As a special constraint\n   on constructors, no value may be returned; doing so will cause a\n   ``TypeError`` to be raised at runtime.\n\nobject.__del__(self)\n\n   Called when the instance is about to be destroyed.  This is also\n   called a destructor.  If a base class has a ``__del__()`` method,\n   the derived class\'s ``__del__()`` method, if any, must explicitly\n   call it to ensure proper deletion of the base class part of the\n   instance.  Note that it is possible (though not recommended!) for\n   the ``__del__()`` method to postpone destruction of the instance by\n   creating a new reference to it.  It may then be called at a later\n   time when this new reference is deleted.  It is not guaranteed that\n   ``__del__()`` methods are called for objects that still exist when\n   the interpreter exits.\n\n   Note: ``del x`` doesn\'t directly call ``x.__del__()`` --- the former\n     decrements the reference count for ``x`` by one, and the latter\n     is only called when ``x``\'s reference count reaches zero.  Some\n     common situations that may prevent the reference count of an\n     object from going to zero include: circular references between\n     objects (e.g., a doubly-linked list or a tree data structure with\n     parent and child pointers); a reference to the object on the\n     stack frame of a function that caught an exception (the traceback\n     stored in ``sys.exc_info()[2]`` keeps the stack frame alive); or\n     a reference to the object on the stack frame that raised an\n     unhandled exception in interactive mode (the traceback stored in\n     ``sys.last_traceback`` keeps the stack frame alive).  The first\n     situation can only be remedied by explicitly breaking the cycles;\n     the latter two situations can be resolved by storing ``None`` in\n     ``sys.last_traceback``. Circular references which are garbage are\n     detected when the option cycle detector is enabled (it\'s on by\n     default), but can only be cleaned up if there are no Python-\n     level ``__del__()`` methods involved. Refer to the documentation\n     for the ``gc`` module for more information about how\n     ``__del__()`` methods are handled by the cycle detector,\n     particularly the description of the ``garbage`` value.\n\n   Warning: Due to the precarious circumstances under which ``__del__()``\n     methods are invoked, exceptions that occur during their execution\n     are ignored, and a warning is printed to ``sys.stderr`` instead.\n     Also, when ``__del__()`` is invoked in response to a module being\n     deleted (e.g., when execution of the program is done), other\n     globals referenced by the ``__del__()`` method may already have\n     been deleted or in the process of being torn down (e.g. the\n     import machinery shutting down).  For this reason, ``__del__()``\n     methods should do the absolute minimum needed to maintain\n     external invariants.  Starting with version 1.5, Python\n     guarantees that globals whose name begins with a single\n     underscore are deleted from their module before other globals are\n     deleted; if no other references to such globals exist, this may\n     help in assuring that imported modules are still available at the\n     time when the ``__del__()`` method is called.\n\nobject.__repr__(self)\n\n   Called by the ``repr()`` built-in function to compute the\n   "official" string representation of an object.  If at all possible,\n   this should look like a valid Python expression that could be used\n   to recreate an object with the same value (given an appropriate\n   environment).  If this is not possible, a string of the form\n   ``<...some useful description...>`` should be returned. The return\n   value must be a string object. If a class defines ``__repr__()``\n   but not ``__str__()``, then ``__repr__()`` is also used when an\n   "informal" string representation of instances of that class is\n   required.\n\n   This is typically used for debugging, so it is important that the\n   representation is information-rich and unambiguous.\n\nobject.__str__(self)\n\n   Called by the ``str()`` built-in function and by the ``print()``\n   function to compute the "informal" string representation of an\n   object.  This differs from ``__repr__()`` in that it does not have\n   to be a valid Python expression: a more convenient or concise\n   representation may be used instead. The return value must be a\n   string object.\n\nobject.__format__(self, format_spec)\n\n   Called by the ``format()`` built-in function (and by extension, the\n   ``format()`` method of class ``str``) to produce a "formatted"\n   string representation of an object. The ``format_spec`` argument is\n   a string that contains a description of the formatting options\n   desired. The interpretation of the ``format_spec`` argument is up\n   to the type implementing ``__format__()``, however most classes\n   will either delegate formatting to one of the built-in types, or\n   use a similar formatting option syntax.\n\n   See *Format Specification Mini-Language* for a description of the\n   standard formatting syntax.\n\n   The return value must be a string object.\n\nobject.__lt__(self, other)\nobject.__le__(self, other)\nobject.__eq__(self, other)\nobject.__ne__(self, other)\nobject.__gt__(self, other)\nobject.__ge__(self, other)\n\n   These are the so-called "rich comparison" methods. The\n   correspondence between operator symbols and method names is as\n   follows: ``x<y`` calls ``x.__lt__(y)``, ``x<=y`` calls\n   ``x.__le__(y)``, ``x==y`` calls ``x.__eq__(y)``, ``x!=y`` calls\n   ``x.__ne__(y)``, ``x>y`` calls ``x.__gt__(y)``, and ``x>=y`` calls\n   ``x.__ge__(y)``.\n\n   A rich comparison method may return the singleton\n   ``NotImplemented`` if it does not implement the operation for a\n   given pair of arguments. By convention, ``False`` and ``True`` are\n   returned for a successful comparison. However, these methods can\n   return any value, so if the comparison operator is used in a\n   Boolean context (e.g., in the condition of an ``if`` statement),\n   Python will call ``bool()`` on the value to determine if the result\n   is true or false.\n\n   There are no implied relationships among the comparison operators.\n   The truth of ``x==y`` does not imply that ``x!=y`` is false.\n   Accordingly, when defining ``__eq__()``, one should also define\n   ``__ne__()`` so that the operators will behave as expected.  See\n   the paragraph on ``__hash__()`` for some important notes on\n   creating *hashable* objects which support custom comparison\n   operations and are usable as dictionary keys.\n\n   There are no swapped-argument versions of these methods (to be used\n   when the left argument does not support the operation but the right\n   argument does); rather, ``__lt__()`` and ``__gt__()`` are each\n   other\'s reflection, ``__le__()`` and ``__ge__()`` are each other\'s\n   reflection, and ``__eq__()`` and ``__ne__()`` are their own\n   reflection.\n\n   Arguments to rich comparison methods are never coerced.\n\n   To automatically generate ordering operations from a single root\n   operation, see the Total Ordering recipe in the ASPN cookbook.\n\nobject.__hash__(self)\n\n   Called by built-in function ``hash()`` and for operations on\n   members of hashed collections including ``set``, ``frozenset``, and\n   ``dict``.  ``__hash__()`` should return an integer.  The only\n   required property is that objects which compare equal have the same\n   hash value; it is advised to somehow mix together (e.g. using\n   exclusive or) the hash values for the components of the object that\n   also play a part in comparison of objects.\n\n   If a class does not define an ``__eq__()`` method it should not\n   define a ``__hash__()`` operation either; if it defines\n   ``__eq__()`` but not ``__hash__()``, its instances will not be\n   usable as items in hashable collections.  If a class defines\n   mutable objects and implements an ``__eq__()`` method, it should\n   not implement ``__hash__()``, since the implementation of hashable\n   collections requires that a key\'s hash value is immutable (if the\n   object\'s hash value changes, it will be in the wrong hash bucket).\n\n   User-defined classes have ``__eq__()`` and ``__hash__()`` methods\n   by default; with them, all objects compare unequal (except with\n   themselves) and ``x.__hash__()`` returns ``id(x)``.\n\n   Classes which inherit a ``__hash__()`` method from a parent class\n   but change the meaning of ``__eq__()`` such that the hash value\n   returned is no longer appropriate (e.g. by switching to a value-\n   based concept of equality instead of the default identity based\n   equality) can explicitly flag themselves as being unhashable by\n   setting ``__hash__ = None`` in the class definition. Doing so means\n   that not only will instances of the class raise an appropriate\n   ``TypeError`` when a program attempts to retrieve their hash value,\n   but they will also be correctly identified as unhashable when\n   checking ``isinstance(obj, collections.Hashable)`` (unlike classes\n   which define their own ``__hash__()`` to explicitly raise\n   ``TypeError``).\n\n   If a class that overrides ``__eq__()`` needs to retain the\n   implementation of ``__hash__()`` from a parent class, the\n   interpreter must be told this explicitly by setting ``__hash__ =\n   <ParentClass>.__hash__``. Otherwise the inheritance of\n   ``__hash__()`` will be blocked, just as if ``__hash__`` had been\n   explicitly set to ``None``.\n\nobject.__bool__(self)\n\n   Called to implement truth value testing and the built-in operation\n   ``bool()``; should return ``False`` or ``True``, or their integer\n   equivalents ``0`` or ``1``.  When this method is not defined,\n   ``__len__()`` is called, if it is defined, and the object is\n   considered true if its result is nonzero. If a class defines\n   neither ``__len__()`` nor ``__bool__()``, all its instances are\n   considered true.\n\n\nCustomizing attribute access\n============================\n\nThe following methods can be defined to customize the meaning of\nattribute access (use of, assignment to, or deletion of ``x.name``)\nfor class instances.\n\nobject.__getattr__(self, name)\n\n   Called when an attribute lookup has not found the attribute in the\n   usual places (i.e. it is not an instance attribute nor is it found\n   in the class tree for ``self``).  ``name`` is the attribute name.\n   This method should return the (computed) attribute value or raise\n   an ``AttributeError`` exception.\n\n   Note that if the attribute is found through the normal mechanism,\n   ``__getattr__()`` is not called.  (This is an intentional asymmetry\n   between ``__getattr__()`` and ``__setattr__()``.) This is done both\n   for efficiency reasons and because otherwise ``__getattr__()``\n   would have no way to access other attributes of the instance.  Note\n   that at least for instance variables, you can fake total control by\n   not inserting any values in the instance attribute dictionary (but\n   instead inserting them in another object).  See the\n   ``__getattribute__()`` method below for a way to actually get total\n   control over attribute access.\n\nobject.__getattribute__(self, name)\n\n   Called unconditionally to implement attribute accesses for\n   instances of the class. If the class also defines\n   ``__getattr__()``, the latter will not be called unless\n   ``__getattribute__()`` either calls it explicitly or raises an\n   ``AttributeError``. This method should return the (computed)\n   attribute value or raise an ``AttributeError`` exception. In order\n   to avoid infinite recursion in this method, its implementation\n   should always call the base class method with the same name to\n   access any attributes it needs, for example,\n   ``object.__getattribute__(self, name)``.\n\n   Note: This method may still be bypassed when looking up special methods\n     as the result of implicit invocation via language syntax or\n     builtin functions. See *Special method lookup*.\n\nobject.__setattr__(self, name, value)\n\n   Called when an attribute assignment is attempted.  This is called\n   instead of the normal mechanism (i.e. store the value in the\n   instance dictionary). *name* is the attribute name, *value* is the\n   value to be assigned to it.\n\n   If ``__setattr__()`` wants to assign to an instance attribute, it\n   should call the base class method with the same name, for example,\n   ``object.__setattr__(self, name, value)``.\n\nobject.__delattr__(self, name)\n\n   Like ``__setattr__()`` but for attribute deletion instead of\n   assignment.  This should only be implemented if ``del obj.name`` is\n   meaningful for the object.\n\nobject.__dir__(self)\n\n   Called when ``dir()`` is called on the object.  A list must be\n   returned.\n\n\nImplementing Descriptors\n------------------------\n\nThe following methods only apply when an instance of the class\ncontaining the method (a so-called *descriptor* class) appears in the\nclass dictionary of another class, known as the *owner* class.  In the\nexamples below, "the attribute" refers to the attribute whose name is\nthe key of the property in the owner class\' ``__dict__``.\n\nobject.__get__(self, instance, owner)\n\n   Called to get the attribute of the owner class (class attribute\n   access) or of an instance of that class (instance attribute\n   access). *owner* is always the owner class, while *instance* is the\n   instance that the attribute was accessed through, or ``None`` when\n   the attribute is accessed through the *owner*.  This method should\n   return the (computed) attribute value or raise an\n   ``AttributeError`` exception.\n\nobject.__set__(self, instance, value)\n\n   Called to set the attribute on an instance *instance* of the owner\n   class to a new value, *value*.\n\nobject.__delete__(self, instance)\n\n   Called to delete the attribute on an instance *instance* of the\n   owner class.\n\n\nInvoking Descriptors\n--------------------\n\nIn general, a descriptor is an object attribute with "binding\nbehavior", one whose attribute access has been overridden by methods\nin the descriptor protocol:  ``__get__()``, ``__set__()``, and\n``__delete__()``. If any of those methods are defined for an object,\nit is said to be a descriptor.\n\nThe default behavior for attribute access is to get, set, or delete\nthe attribute from an object\'s dictionary. For instance, ``a.x`` has a\nlookup chain starting with ``a.__dict__[\'x\']``, then\n``type(a).__dict__[\'x\']``, and continuing through the base classes of\n``type(a)`` excluding metaclasses.\n\nHowever, if the looked-up value is an object defining one of the\ndescriptor methods, then Python may override the default behavior and\ninvoke the descriptor method instead.  Where this occurs in the\nprecedence chain depends on which descriptor methods were defined and\nhow they were called.\n\nThe starting point for descriptor invocation is a binding, ``a.x``.\nHow the arguments are assembled depends on ``a``:\n\nDirect Call\n   The simplest and least common call is when user code directly\n   invokes a descriptor method:    ``x.__get__(a)``.\n\nInstance Binding\n   If binding to an object instance, ``a.x`` is transformed into the\n   call: ``type(a).__dict__[\'x\'].__get__(a, type(a))``.\n\nClass Binding\n   If binding to a class, ``A.x`` is transformed into the call:\n   ``A.__dict__[\'x\'].__get__(None, A)``.\n\nSuper Binding\n   If ``a`` is an instance of ``super``, then the binding ``super(B,\n   obj).m()`` searches ``obj.__class__.__mro__`` for the base class\n   ``A`` immediately preceding ``B`` and then invokes the descriptor\n   with the call: ``A.__dict__[\'m\'].__get__(obj, A)``.\n\nFor instance bindings, the precedence of descriptor invocation depends\non the which descriptor methods are defined.  Normally, data\ndescriptors define both ``__get__()`` and ``__set__()``, while non-\ndata descriptors have just the ``__get__()`` method.  Data descriptors\nalways override a redefinition in an instance dictionary.  In\ncontrast, non-data descriptors can be overridden by instances. [2]\n\nPython methods (including ``staticmethod()`` and ``classmethod()``)\nare implemented as non-data descriptors.  Accordingly, instances can\nredefine and override methods.  This allows individual instances to\nacquire behaviors that differ from other instances of the same class.\n\nThe ``property()`` function is implemented as a data descriptor.\nAccordingly, instances cannot override the behavior of a property.\n\n\n__slots__\n---------\n\nBy default, instances of classes have a dictionary for attribute\nstorage.  This wastes space for objects having very few instance\nvariables.  The space consumption can become acute when creating large\nnumbers of instances.\n\nThe default can be overridden by defining *__slots__* in a class\ndefinition. The *__slots__* declaration takes a sequence of instance\nvariables and reserves just enough space in each instance to hold a\nvalue for each variable.  Space is saved because *__dict__* is not\ncreated for each instance.\n\nobject.__slots__\n\n   This class variable can be assigned a string, iterable, or sequence\n   of strings with variable names used by instances.  If defined in a\n   class, *__slots__* reserves space for the declared variables and\n   prevents the automatic creation of *__dict__* and *__weakref__* for\n   each instance.\n\n\nNotes on using *__slots__*\n~~~~~~~~~~~~~~~~~~~~~~~~~~\n\n* When inheriting from a class without *__slots__*, the *__dict__*\n  attribute of that class will always be accessible, so a *__slots__*\n  definition in the subclass is meaningless.\n\n* Without a *__dict__* variable, instances cannot be assigned new\n  variables not listed in the *__slots__* definition.  Attempts to\n  assign to an unlisted variable name raises ``AttributeError``. If\n  dynamic assignment of new variables is desired, then add\n  ``\'__dict__\'`` to the sequence of strings in the *__slots__*\n  declaration.\n\n* Without a *__weakref__* variable for each instance, classes defining\n  *__slots__* do not support weak references to its instances. If weak\n  reference support is needed, then add ``\'__weakref__\'`` to the\n  sequence of strings in the *__slots__* declaration.\n\n* *__slots__* are implemented at the class level by creating\n  descriptors (*Implementing Descriptors*) for each variable name.  As\n  a result, class attributes cannot be used to set default values for\n  instance variables defined by *__slots__*; otherwise, the class\n  attribute would overwrite the descriptor assignment.\n\n* If a class defines a slot also defined in a base class, the instance\n  variable defined by the base class slot is inaccessible (except by\n  retrieving its descriptor directly from the base class). This\n  renders the meaning of the program undefined.  In the future, a\n  check may be added to prevent this.\n\n* The action of a *__slots__* declaration is limited to the class\n  where it is defined.  As a result, subclasses will have a *__dict__*\n  unless they also define *__slots__*.\n\n* Nonempty *__slots__* does not work for classes derived from\n  "variable-length" built-in types such as ``int``, ``str`` and\n  ``tuple``.\n\n* Any non-string iterable may be assigned to *__slots__*. Mappings may\n  also be used; however, in the future, special meaning may be\n  assigned to the values corresponding to each key.\n\n* *__class__* assignment works only if both classes have the same\n  *__slots__*.\n\n\nCustomizing class creation\n==========================\n\nBy default, classes are constructed using ``type()``. A class\ndefinition is read into a separate namespace and the value of class\nname is bound to the result of ``type(name, bases, dict)``.\n\nWhen the class definition is read, if a callable ``metaclass`` keyword\nargument is passed after the bases in the class definition, the\ncallable given will be called instead of ``type()``.  If other keyword\narguments are passed, they will also be passed to the metaclass.  This\nallows classes or functions to be written which monitor or alter the\nclass creation process:\n\n* Modifying the class dictionary prior to the class being created.\n\n* Returning an instance of another class -- essentially performing the\n  role of a factory function.\n\nThese steps will have to be performed in the metaclass\'s ``__new__()``\nmethod -- ``type.__new__()`` can then be called from this method to\ncreate a class with different properties.  This example adds a new\nelement to the class dictionary before creating the class:\n\n   class metacls(type):\n       def __new__(mcs, name, bases, dict):\n           dict[\'foo\'] = \'metacls was here\'\n           return type.__new__(mcs, name, bases, dict)\n\nYou can of course also override other class methods (or add new\nmethods); for example defining a custom ``__call__()`` method in the\nmetaclass allows custom behavior when the class is called, e.g. not\nalways creating a new instance.\n\nIf the metaclass has a ``__prepare__()`` attribute (usually\nimplemented as a class or static method), it is called before the\nclass body is evaluated with the name of the class and a tuple of its\nbases for arguments.  It should return an object that supports the\nmapping interface that will be used to store the namespace of the\nclass.  The default is a plain dictionary.  This could be used, for\nexample, to keep track of the order that class attributes are declared\nin by returning an ordered dictionary.\n\nThe appropriate metaclass is determined by the following precedence\nrules:\n\n* If the ``metaclass`` keyword argument is based with the bases, it is\n  used.\n\n* Otherwise, if there is at least one base class, its metaclass is\n  used.\n\n* Otherwise, the default metaclass (``type``) is used.\n\nThe potential uses for metaclasses are boundless. Some ideas that have\nbeen explored including logging, interface checking, automatic\ndelegation, automatic property creation, proxies, frameworks, and\nautomatic resource locking/synchronization.\n\nHere is an example of a metaclass that uses an\n``collections.OrderedDict`` to remember the order that class members\nwere defined:\n\n   class OrderedClass(type):\n\n        @classmethod\n        def __prepare__(metacls, name, bases, **kwds):\n           return collections.OrderedDict()\n\n        def __new__(cls, name, bases, classdict):\n           result = type.__new__(cls, name, bases, dict(classdict))\n           result.members = tuple(classdict)\n           return result\n\n   class A(metaclass=OrderedClass):\n       def one(self): pass\n       def two(self): pass\n       def three(self): pass\n       def four(self): pass\n\n   >>> A.members\n   (\'__module__\', \'one\', \'two\', \'three\', \'four\')\n\nWhen the class definition for *A* gets executed, the process begins\nwith calling the metaclass\'s ``__prepare__()`` method which returns an\nempty ``collections.OrderedDict``.  That mapping records the methods\nand attributes of *A* as they are defined within the body of the class\nstatement. Once those definitions are executed, the ordered dictionary\nis fully populated and the metaclass\'s ``__new__()`` method gets\ninvoked.  That method builds the new type and it saves the ordered\ndictionary keys in an attribute called *members*.\n\n\nEmulating callable objects\n==========================\n\nobject.__call__(self[, args...])\n\n   Called when the instance is "called" as a function; if this method\n   is defined, ``x(arg1, arg2, ...)`` is a shorthand for\n   ``x.__call__(arg1, arg2, ...)``.\n\n\nEmulating container types\n=========================\n\nThe following methods can be defined to implement container objects.\nContainers usually are sequences (such as lists or tuples) or mappings\n(like dictionaries), but can represent other containers as well.  The\nfirst set of methods is used either to emulate a sequence or to\nemulate a mapping; the difference is that for a sequence, the\nallowable keys should be the integers *k* for which ``0 <= k < N``\nwhere *N* is the length of the sequence, or slice objects, which\ndefine a range of items.  It is also recommended that mappings provide\nthe methods ``keys()``, ``values()``, ``items()``, ``get()``,\n``clear()``, ``setdefault()``, ``pop()``, ``popitem()``, ``copy()``,\nand ``update()`` behaving similar to those for Python\'s standard\ndictionary objects.  The ``collections`` module provides a\n``MutableMapping`` abstract base class to help create those methods\nfrom a base set of ``__getitem__()``, ``__setitem__()``,\n``__delitem__()``, and ``keys()``. Mutable sequences should provide\nmethods ``append()``, ``count()``, ``index()``, ``extend()``,\n``insert()``, ``pop()``, ``remove()``, ``reverse()`` and ``sort()``,\nlike Python standard list objects.  Finally, sequence types should\nimplement addition (meaning concatenation) and multiplication (meaning\nrepetition) by defining the methods ``__add__()``, ``__radd__()``,\n``__iadd__()``, ``__mul__()``, ``__rmul__()`` and ``__imul__()``\ndescribed below; they should not define other numerical operators.  It\nis recommended that both mappings and sequences implement the\n``__contains__()`` method to allow efficient use of the ``in``\noperator; for mappings, ``in`` should search the mapping\'s keys; for\nsequences, it should search through the values.  It is further\nrecommended that both mappings and sequences implement the\n``__iter__()`` method to allow efficient iteration through the\ncontainer; for mappings, ``__iter__()`` should be the same as\n``keys()``; for sequences, it should iterate through the values.\n\nobject.__len__(self)\n\n   Called to implement the built-in function ``len()``.  Should return\n   the length of the object, an integer ``>=`` 0.  Also, an object\n   that doesn\'t define a ``__bool__()`` method and whose ``__len__()``\n   method returns zero is considered to be false in a Boolean context.\n\nNote: Slicing is done exclusively with the following three methods.  A\n  call like\n\n     a[1:2] = b\n\n  is translated to\n\n     a[slice(1, 2, None)] = b\n\n  and so forth.  Missing slice items are always filled in with\n  ``None``.\n\nobject.__getitem__(self, key)\n\n   Called to implement evaluation of ``self[key]``. For sequence\n   types, the accepted keys should be integers and slice objects.\n   Note that the special interpretation of negative indexes (if the\n   class wishes to emulate a sequence type) is up to the\n   ``__getitem__()`` method. If *key* is of an inappropriate type,\n   ``TypeError`` may be raised; if of a value outside the set of\n   indexes for the sequence (after any special interpretation of\n   negative values), ``IndexError`` should be raised. For mapping\n   types, if *key* is missing (not in the container), ``KeyError``\n   should be raised.\n\n   Note: ``for`` loops expect that an ``IndexError`` will be raised for\n     illegal indexes to allow proper detection of the end of the\n     sequence.\n\nobject.__setitem__(self, key, value)\n\n   Called to implement assignment to ``self[key]``.  Same note as for\n   ``__getitem__()``.  This should only be implemented for mappings if\n   the objects support changes to the values for keys, or if new keys\n   can be added, or for sequences if elements can be replaced.  The\n   same exceptions should be raised for improper *key* values as for\n   the ``__getitem__()`` method.\n\nobject.__delitem__(self, key)\n\n   Called to implement deletion of ``self[key]``.  Same note as for\n   ``__getitem__()``.  This should only be implemented for mappings if\n   the objects support removal of keys, or for sequences if elements\n   can be removed from the sequence.  The same exceptions should be\n   raised for improper *key* values as for the ``__getitem__()``\n   method.\n\nobject.__iter__(self)\n\n   This method is called when an iterator is required for a container.\n   This method should return a new iterator object that can iterate\n   over all the objects in the container.  For mappings, it should\n   iterate over the keys of the container, and should also be made\n   available as the method ``keys()``.\n\n   Iterator objects also need to implement this method; they are\n   required to return themselves.  For more information on iterator\n   objects, see *Iterator Types*.\n\nobject.__reversed__(self)\n\n   Called (if present) by the ``reversed()`` builtin to implement\n   reverse iteration.  It should return a new iterator object that\n   iterates over all the objects in the container in reverse order.\n\n   If the ``__reversed__()`` method is not provided, the\n   ``reversed()`` builtin will fall back to using the sequence\n   protocol (``__len__()`` and ``__getitem__()``).  Objects that\n   support the sequence protocol should only provide\n   ``__reversed__()`` if they can provide an implementation that is\n   more efficient than the one provided by ``reversed()``.\n\nThe membership test operators (``in`` and ``not in``) are normally\nimplemented as an iteration through a sequence.  However, container\nobjects can supply the following special method with a more efficient\nimplementation, which also does not require the object be a sequence.\n\nobject.__contains__(self, item)\n\n   Called to implement membership test operators.  Should return true\n   if *item* is in *self*, false otherwise.  For mapping objects, this\n   should consider the keys of the mapping rather than the values or\n   the key-item pairs.\n\n\nEmulating numeric types\n=======================\n\nThe following methods can be defined to emulate numeric objects.\nMethods corresponding to operations that are not supported by the\nparticular kind of number implemented (e.g., bitwise operations for\nnon-integral numbers) should be left undefined.\n\nobject.__add__(self, other)\nobject.__sub__(self, other)\nobject.__mul__(self, other)\nobject.__truediv__(self, other)\nobject.__floordiv__(self, other)\nobject.__mod__(self, other)\nobject.__divmod__(self, other)\nobject.__pow__(self, other[, modulo])\nobject.__lshift__(self, other)\nobject.__rshift__(self, other)\nobject.__and__(self, other)\nobject.__xor__(self, other)\nobject.__or__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations (``+``, ``-``, ``*``, ``/``, ``//``, ``%``,\n   ``divmod()``, ``pow()``, ``**``, ``<<``, ``>>``, ``&``, ``^``,\n   ``|``).  For instance, to evaluate the expression ``x + y``, where\n   *x* is an instance of a class that has an ``__add__()`` method,\n   ``x.__add__(y)`` is called.  The ``__divmod__()`` method should be\n   the equivalent to using ``__floordiv__()`` and ``__mod__()``; it\n   should not be related to ``__truediv__()``.  Note that\n   ``__pow__()`` should be defined to accept an optional third\n   argument if the ternary version of the built-in ``pow()`` function\n   is to be supported.\n\n   If one of those methods does not support the operation with the\n   supplied arguments, it should return ``NotImplemented``.\n\nobject.__radd__(self, other)\nobject.__rsub__(self, other)\nobject.__rmul__(self, other)\nobject.__rtruediv__(self, other)\nobject.__rfloordiv__(self, other)\nobject.__rmod__(self, other)\nobject.__rdivmod__(self, other)\nobject.__rpow__(self, other)\nobject.__rlshift__(self, other)\nobject.__rrshift__(self, other)\nobject.__rand__(self, other)\nobject.__rxor__(self, other)\nobject.__ror__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations (``+``, ``-``, ``*``, ``/``, ``//``, ``%``,\n   ``divmod()``, ``pow()``, ``**``, ``<<``, ``>>``, ``&``, ``^``,\n   ``|``) with reflected (swapped) operands. These functions are only\n   called if the left operand does not support the corresponding\n   operation and the operands are of different types. [3]  For\n   instance, to evaluate the expression ``x - y``, where *y* is an\n   instance of a class that has an ``__rsub__()`` method,\n   ``y.__rsub__(x)`` is called if ``x.__sub__(y)`` returns\n   *NotImplemented*.\n\n   Note that ternary ``pow()`` will not try calling ``__rpow__()``\n   (the coercion rules would become too complicated).\n\n   Note: If the right operand\'s type is a subclass of the left operand\'s\n     type and that subclass provides the reflected method for the\n     operation, this method will be called before the left operand\'s\n     non-reflected method.  This behavior allows subclasses to\n     override their ancestors\' operations.\n\nobject.__iadd__(self, other)\nobject.__isub__(self, other)\nobject.__imul__(self, other)\nobject.__itruediv__(self, other)\nobject.__ifloordiv__(self, other)\nobject.__imod__(self, other)\nobject.__ipow__(self, other[, modulo])\nobject.__ilshift__(self, other)\nobject.__irshift__(self, other)\nobject.__iand__(self, other)\nobject.__ixor__(self, other)\nobject.__ior__(self, other)\n\n   These methods are called to implement the augmented arithmetic\n   assignments (``+=``, ``-=``, ``*=``, ``/=``, ``//=``, ``%=``,\n   ``**=``, ``<<=``, ``>>=``, ``&=``, ``^=``, ``|=``).  These methods\n   should attempt to do the operation in-place (modifying *self*) and\n   return the result (which could be, but does not have to be,\n   *self*).  If a specific method is not defined, the augmented\n   assignment falls back to the normal methods.  For instance, to\n   execute the statement ``x += y``, where *x* is an instance of a\n   class that has an ``__iadd__()`` method, ``x.__iadd__(y)`` is\n   called.  If *x* is an instance of a class that does not define a\n   ``__iadd__()`` method, ``x.__add__(y)`` and ``y.__radd__(x)`` are\n   considered, as with the evaluation of ``x + y``.\n\nobject.__neg__(self)\nobject.__pos__(self)\nobject.__abs__(self)\nobject.__invert__(self)\n\n   Called to implement the unary arithmetic operations (``-``, ``+``,\n   ``abs()`` and ``~``).\n\nobject.__complex__(self)\nobject.__int__(self)\nobject.__float__(self)\nobject.__round__(self[, n])\n\n   Called to implement the built-in functions ``complex()``,\n   ``int()``, ``float()`` and ``round()``.  Should return a value of\n   the appropriate type.\n\nobject.__index__(self)\n\n   Called to implement ``operator.index()``.  Also called whenever\n   Python needs an integer object (such as in slicing, or in the\n   built-in ``bin()``, ``hex()`` and ``oct()`` functions). Must return\n   an integer.\n\n\nWith Statement Context Managers\n===============================\n\nA *context manager* is an object that defines the runtime context to\nbe established when executing a ``with`` statement. The context\nmanager handles the entry into, and the exit from, the desired runtime\ncontext for the execution of the block of code.  Context managers are\nnormally invoked using the ``with`` statement (described in section\n*The with statement*), but can also be used by directly invoking their\nmethods.\n\nTypical uses of context managers include saving and restoring various\nkinds of global state, locking and unlocking resources, closing opened\nfiles, etc.\n\nFor more information on context managers, see *Context Manager Types*.\n\nobject.__enter__(self)\n\n   Enter the runtime context related to this object. The ``with``\n   statement will bind this method\'s return value to the target(s)\n   specified in the ``as`` clause of the statement, if any.\n\nobject.__exit__(self, exc_type, exc_value, traceback)\n\n   Exit the runtime context related to this object. The parameters\n   describe the exception that caused the context to be exited. If the\n   context was exited without an exception, all three arguments will\n   be ``None``.\n\n   If an exception is supplied, and the method wishes to suppress the\n   exception (i.e., prevent it from being propagated), it should\n   return a true value. Otherwise, the exception will be processed\n   normally upon exit from this method.\n\n   Note that ``__exit__()`` methods should not reraise the passed-in\n   exception; this is the caller\'s responsibility.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n\n\nSpecial method lookup\n=====================\n\nFor custom classes, implicit invocations of special methods are only\nguaranteed to work correctly if defined on an object\'s type, not in\nthe object\'s instance dictionary.  That behaviour is the reason why\nthe following code raises an exception:\n\n   >>> class C(object):\n   ...     pass\n   ...\n   >>> c = C()\n   >>> c.__len__ = lambda: 5\n   >>> len(c)\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   TypeError: object of type \'C\' has no len()\n\nThe rationale behind this behaviour lies with a number of special\nmethods such as ``__hash__()`` and ``__repr__()`` that are implemented\nby all objects, including type objects. If the implicit lookup of\nthese methods used the conventional lookup process, they would fail\nwhen invoked on the type object itself:\n\n   >>> 1 .__hash__() == hash(1)\n   True\n   >>> int.__hash__() == hash(int)\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   TypeError: descriptor \'__hash__\' of \'int\' object needs an argument\n\nIncorrectly attempting to invoke an unbound method of a class in this\nway is sometimes referred to as \'metaclass confusion\', and is avoided\nby bypassing the instance when looking up special methods:\n\n   >>> type(1).__hash__(1) == hash(1)\n   True\n   >>> type(int).__hash__(int) == hash(int)\n   True\n\nIn addition to bypassing any instance attributes in the interest of\ncorrectness, implicit special method lookup generally also bypasses\nthe ``__getattribute__()`` method even of the object\'s metaclass:\n\n   >>> class Meta(type):\n   ...    def __getattribute__(*args):\n   ...       print("Metaclass getattribute invoked")\n   ...       return type.__getattribute__(*args)\n   ...\n   >>> class C(object, metaclass=Meta):\n   ...     def __len__(self):\n   ...         return 10\n   ...     def __getattribute__(*args):\n   ...         print("Class getattribute invoked")\n   ...         return object.__getattribute__(*args)\n   ...\n   >>> c = C()\n   >>> c.__len__()                 # Explicit lookup via instance\n   Class getattribute invoked\n   10\n   >>> type(c).__len__(c)          # Explicit lookup via type\n   Metaclass getattribute invoked\n   10\n   >>> len(c)                      # Implicit lookup\n   10\n\nBypassing the ``__getattribute__()`` machinery in this fashion\nprovides significant scope for speed optimisations within the\ninterpreter, at the cost of some flexibility in the handling of\nspecial methods (the special method *must* be set on the class object\nitself in order to be consistently invoked by the interpreter).\n\n-[ Footnotes ]-\n\n[1] It *is* possible in some cases to change an object\'s type, under\n    certain controlled conditions. It generally isn\'t a good idea\n    though, since it can lead to some very strange behaviour if it is\n    handled incorrectly.\n\n[2] A descriptor can define any combination of ``__get__()``,\n    ``__set__()`` and ``__delete__()``.  If it does not define\n    ``__get__()``, then accessing the attribute even on an instance\n    will return the descriptor object itself.  If the descriptor\n    defines ``__set__()`` and/or ``__delete__()``, it is a data\n    descriptor; if it defines neither, it is a non-data descriptor.\n\n[3] For operands of the same type, it is assumed that if the non-\n    reflected method (such as ``__add__()``) fails the operation is\n    not supported, which is why the reflected method is not called.\n',
- 'string-methods': '\nString Methods\n**************\n\nString objects support the methods listed below.  Note that none of\nthese methods take keyword arguments.\n\nIn addition, Python\'s strings support the sequence type methods\ndescribed in the *Sequence Types --- str, bytes, bytearray, list,\ntuple, range* section. To output formatted strings, see the *String\nFormatting* section. Also, see the ``re`` module for string functions\nbased on regular expressions.\n\nstr.capitalize()\n\n   Return a copy of the string with only its first character\n   capitalized.\n\nstr.center(width[, fillchar])\n\n   Return centered in a string of length *width*. Padding is done\n   using the specified *fillchar* (default is a space).\n\nstr.count(sub[, start[, end]])\n\n   Return the number of non-overlapping occurrences of substring *sub*\n   in the range [*start*, *end*].  Optional arguments *start* and\n   *end* are interpreted as in slice notation.\n\nstr.encode([encoding[, errors]])\n\n   Return an encoded version of the string as a bytes object.  Default\n   encoding is the current default string encoding.  *errors* may be\n   given to set a different error handling scheme.  The default for\n   *errors* is ``\'strict\'``, meaning that encoding errors raise a\n   ``UnicodeError``.  Other possible values are ``\'ignore\'``,\n   ``\'replace\'``, ``\'xmlcharrefreplace\'``, ``\'backslashreplace\'`` and\n   any other name registered via ``codecs.register_error()``, see\n   section *Codec Base Classes*. For a list of possible encodings, see\n   section *Standard Encodings*.\n\nstr.endswith(suffix[, start[, end]])\n\n   Return ``True`` if the string ends with the specified *suffix*,\n   otherwise return ``False``.  *suffix* can also be a tuple of\n   suffixes to look for.  With optional *start*, test beginning at\n   that position.  With optional *end*, stop comparing at that\n   position.\n\nstr.expandtabs([tabsize])\n\n   Return a copy of the string where all tab characters are replaced\n   by one or more spaces, depending on the current column and the\n   given tab size.  The column number is reset to zero after each\n   newline occurring in the string. If *tabsize* is not given, a tab\n   size of ``8`` characters is assumed.  This doesn\'t understand other\n   non-printing characters or escape sequences.\n\nstr.find(sub[, start[, end]])\n\n   Return the lowest index in the string where substring *sub* is\n   found, such that *sub* is contained in the range [*start*, *end*].\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` if *sub* is not found.\n\nstr.format(*args, **kwargs)\n\n   Perform a string formatting operation.  The *format_string*\n   argument can contain literal text or replacement fields delimited\n   by braces ``{}``.  Each replacement field contains either the\n   numeric index of a positional argument, or the name of a keyword\n   argument.  Returns a copy of *format_string* where each replacement\n   field is replaced with the string value of the corresponding\n   argument.\n\n   >>> "The sum of 1 + 2 is {0}".format(1+2)\n   \'The sum of 1 + 2 is 3\'\n\n   See *Format String Syntax* for a description of the various\n   formatting options that can be specified in format strings.\n\nstr.index(sub[, start[, end]])\n\n   Like ``find()``, but raise ``ValueError`` when the substring is not\n   found.\n\nstr.isalnum()\n\n   Return true if all characters in the string are alphanumeric and\n   there is at least one character, false otherwise.\n\nstr.isalpha()\n\n   Return true if all characters in the string are alphabetic and\n   there is at least one character, false otherwise.\n\nstr.isdecimal()\n\n   Return true if all characters in the string are decimal characters\n   and there is at least one character, false otherwise. Decimal\n   characters include digit characters, and all characters that that\n   can be used to form decimal-radix numbers, e.g. U+0660, ARABIC-\n   INDIC DIGIT ZERO.\n\nstr.isdigit()\n\n   Return true if all characters in the string are digits and there is\n   at least one character, false otherwise.\n\nstr.isidentifier()\n\n   Return true if the string is a valid identifier according to the\n   language definition, section *Identifiers and keywords*.\n\nstr.islower()\n\n   Return true if all cased characters in the string are lowercase and\n   there is at least one cased character, false otherwise.\n\nstr.isnumeric()\n\n   Return true if all characters in the string are numeric characters,\n   and there is at least one character, false otherwise. Numeric\n   characters include digit characters, and all characters that have\n   the Unicode numeric value property, e.g. U+2155, VULGAR FRACTION\n   ONE FIFTH.\n\nstr.isprintable()\n\n   Return true if all characters in the string are printable or the\n   string is empty, false otherwise.  Nonprintable characters are\n   those characters defined in the Unicode character database as\n   "Other" or "Separator", excepting the ASCII space (0x20) which is\n   considered printable.  (Note that printable characters in this\n   context are those which should not be escaped when ``repr()`` is\n   invoked on a string.  It has no bearing on the handling of strings\n   written to ``sys.stdout`` or ``sys.stderr``.)\n\nstr.isspace()\n\n   Return true if there are only whitespace characters in the string\n   and there is at least one character, false otherwise.\n\nstr.istitle()\n\n   Return true if the string is a titlecased string and there is at\n   least one character, for example uppercase characters may only\n   follow uncased characters and lowercase characters only cased ones.\n   Return false otherwise.\n\nstr.isupper()\n\n   Return true if all cased characters in the string are uppercase and\n   there is at least one cased character, false otherwise.\n\nstr.join(seq)\n\n   Return a string which is the concatenation of the strings in the\n   sequence *seq*.  A ``TypeError`` will be raised if there are any\n   non-string values in *seq*, including ``bytes`` objects.  The\n   separator between elements is the string providing this method.\n\nstr.ljust(width[, fillchar])\n\n   Return the string left justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space).  The original string is returned if *width* is less than\n   ``len(s)``.\n\nstr.lower()\n\n   Return a copy of the string converted to lowercase.\n\nstr.lstrip([chars])\n\n   Return a copy of the string with leading characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a prefix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.lstrip()\n   \'spacious   \'\n   >>> \'www.example.com\'.lstrip(\'cmowz.\')\n   \'example.com\'\n\nstatic str.maketrans(x[, y[, z]])\n\n   This static method returns a translation table usable for\n   ``str.translate()``.\n\n   If there is only one argument, it must be a dictionary mapping\n   Unicode ordinals (integers) or characters (strings of length 1) to\n   Unicode ordinals, strings (of arbitrary lengths) or None.\n   Character keys will then be converted to ordinals.\n\n   If there are two arguments, they must be strings of equal length,\n   and in the resulting dictionary, each character in x will be mapped\n   to the character at the same position in y.  If there is a third\n   argument, it must be a string, whose characters will be mapped to\n   None in the result.\n\nstr.partition(sep)\n\n   Split the string at the first occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing the string itself, followed by\n   two empty strings.\n\nstr.replace(old, new[, count])\n\n   Return a copy of the string with all occurrences of substring *old*\n   replaced by *new*.  If the optional argument *count* is given, only\n   the first *count* occurrences are replaced.\n\nstr.rfind(sub[, start[, end]])\n\n   Return the highest index in the string where substring *sub* is\n   found, such that *sub* is contained within s[start,end].  Optional\n   arguments *start* and *end* are interpreted as in slice notation.\n   Return ``-1`` on failure.\n\nstr.rindex(sub[, start[, end]])\n\n   Like ``rfind()`` but raises ``ValueError`` when the substring *sub*\n   is not found.\n\nstr.rjust(width[, fillchar])\n\n   Return the string right justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space). The original string is returned if *width* is less than\n   ``len(s)``.\n\nstr.rpartition(sep)\n\n   Split the string at the last occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing two empty strings, followed by\n   the string itself.\n\nstr.rsplit([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string. If *maxsplit* is given, at most *maxsplit* splits\n   are done, the *rightmost* ones.  If *sep* is not specified or\n   ``None``, any whitespace string is a separator.  Except for\n   splitting from the right, ``rsplit()`` behaves like ``split()``\n   which is described in detail below.\n\nstr.rstrip([chars])\n\n   Return a copy of the string with trailing characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a suffix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.rstrip()\n   \'   spacious\'\n   >>> \'mississippi\'.rstrip(\'ipz\')\n   \'mississ\'\n\nstr.split([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string.  If *maxsplit* is given, at most *maxsplit*\n   splits are done (thus, the list will have at most ``maxsplit+1``\n   elements).  If *maxsplit* is not specified, then there is no limit\n   on the number of splits (all possible splits are made).\n\n   If *sep* is given, consecutive delimiters are not grouped together\n   and are deemed to delimit empty strings (for example,\n   ``\'1,,2\'.split(\',\')`` returns ``[\'1\', \'\', \'2\']``).  The *sep*\n   argument may consist of multiple characters (for example,\n   ``\'1<>2<>3\'.split(\'<>\')`` returns ``[\'1\', \'2\', \'3\']``). Splitting\n   an empty string with a specified separator returns ``[\'\']``.\n\n   If *sep* is not specified or is ``None``, a different splitting\n   algorithm is applied: runs of consecutive whitespace are regarded\n   as a single separator, and the result will contain no empty strings\n   at the start or end if the string has leading or trailing\n   whitespace.  Consequently, splitting an empty string or a string\n   consisting of just whitespace with a ``None`` separator returns\n   ``[]``.\n\n   For example, ``\' 1  2   3  \'.split()`` returns ``[\'1\', \'2\', \'3\']``,\n   and ``\'  1  2   3  \'.split(None, 1)`` returns ``[\'1\', \'2   3  \']``.\n\nstr.splitlines([keepends])\n\n   Return a list of the lines in the string, breaking at line\n   boundaries.  Line breaks are not included in the resulting list\n   unless *keepends* is given and true.\n\nstr.startswith(prefix[, start[, end]])\n\n   Return ``True`` if string starts with the *prefix*, otherwise\n   return ``False``. *prefix* can also be a tuple of prefixes to look\n   for.  With optional *start*, test string beginning at that\n   position.  With optional *end*, stop comparing string at that\n   position.\n\nstr.strip([chars])\n\n   Return a copy of the string with the leading and trailing\n   characters removed. The *chars* argument is a string specifying the\n   set of characters to be removed. If omitted or ``None``, the\n   *chars* argument defaults to removing whitespace. The *chars*\n   argument is not a prefix or suffix; rather, all combinations of its\n   values are stripped:\n\n   >>> \'   spacious   \'.strip()\n   \'spacious\'\n   >>> \'www.example.com\'.strip(\'cmowz.\')\n   \'example\'\n\nstr.swapcase()\n\n   Return a copy of the string with uppercase characters converted to\n   lowercase and vice versa.\n\nstr.title()\n\n   Return a titlecased version of the string: words start with\n   uppercase characters, all remaining cased characters are lowercase.\n\nstr.translate(map)\n\n   Return a copy of the *s* where all characters have been mapped\n   through the *map* which must be a dictionary of Unicode ordinals\n   (integers) to Unicode ordinals, strings or ``None``.  Unmapped\n   characters are left untouched. Characters mapped to ``None`` are\n   deleted.\n\n   You can use ``str.maketrans()`` to create a translation map from\n   character-to-character mappings in different formats.\n\n   Note: An even more flexible approach is to create a custom character\n     mapping codec using the ``codecs`` module (see\n     ``encodings.cp1251`` for an example).\n\nstr.upper()\n\n   Return a copy of the string converted to uppercase.\n\nstr.zfill(width)\n\n   Return the numeric string left filled with zeros in a string of\n   length *width*.  A sign prefix is handled correctly.  The original\n   string is returned if *width* is less than ``len(s)``.\n',
- 'strings': '\nString and Bytes literals\n*************************\n\nString literals are described by the following lexical definitions:\n\n   stringliteral   ::= [stringprefix](shortstring | longstring)\n   stringprefix    ::= "r" | "R"\n   shortstring     ::= "\'" shortstringitem* "\'" | \'"\' shortstringitem* \'"\'\n   longstring      ::= "\'\'\'" longstringitem* "\'\'\'" | \'"""\' longstringitem* \'"""\'\n   shortstringitem ::= shortstringchar | stringescapeseq\n   longstringitem  ::= longstringchar | stringescapeseq\n   shortstringchar ::= <any source character except "\\" or newline or the quote>\n   longstringchar  ::= <any source character except "\\">\n   stringescapeseq ::= "\\" <any source character>\n\n   bytesliteral   ::= bytesprefix(shortbytes | longbytes)\n   bytesprefix    ::= "b" | "B"\n   shortbytes     ::= "\'" shortbytesitem* "\'" | \'"\' shortbytesitem* \'"\'\n   longbytes      ::= "\'\'\'" longbytesitem* "\'\'\'" | \'"""\' longbytesitem* \'"""\'\n   shortbytesitem ::= shortbyteschar | bytesescapeseq\n   longbytesitem  ::= longbyteschar | bytesescapeseq\n   shortbyteschar ::= <any ASCII character except "\\" or newline or the quote>\n   longbyteschar  ::= <any ASCII character except "\\">\n   bytesescapeseq ::= "\\" <any ASCII character>\n\nOne syntactic restriction not indicated by these productions is that\nwhitespace is not allowed between the **stringprefix** or\n**bytesprefix** and the rest of the literal. The source character set\nis defined by the encoding declaration; it is UTF-8 if no encoding\ndeclaration is given in the source file; see section *Encoding\ndeclarations*.\n\nIn plain English: Both types of literals can be enclosed in matching\nsingle quotes (``\'``) or double quotes (``"``).  They can also be\nenclosed in matching groups of three single or double quotes (these\nare generally referred to as *triple-quoted strings*).  The backslash\n(``\\``) character is used to escape characters that otherwise have a\nspecial meaning, such as newline, backslash itself, or the quote\ncharacter.\n\nString literals may optionally be prefixed with a letter ``\'r\'`` or\n``\'R\'``; such strings are called *raw strings* and treat backslashes\nas literal characters.  As a result, ``\'\\U\'`` and ``\'\\u\'`` escapes in\nraw strings are not treated specially.\n\nBytes literals are always prefixed with ``\'b\'`` or ``\'B\'``; they\nproduce an instance of the ``bytes`` type instead of the ``str`` type.\nThey may only contain ASCII characters; bytes with a numeric value of\n128 or greater must be expressed with escapes.\n\nIn triple-quoted strings, unescaped newlines and quotes are allowed\n(and are retained), except that three unescaped quotes in a row\nterminate the string.  (A "quote" is the character used to open the\nstring, i.e. either ``\'`` or ``"``.)\n\nUnless an ``\'r\'`` or ``\'R\'`` prefix is present, escape sequences in\nstrings are interpreted according to rules similar to those used by\nStandard C.  The recognized escape sequences are:\n\n+-------------------+-----------------------------------+---------+\n| Escape Sequence   | Meaning                           | Notes   |\n+===================+===================================+=========+\n| ``\\newline``      | Backslash and newline ignored     |         |\n+-------------------+-----------------------------------+---------+\n| ``\\\\``            | Backslash (``\\``)                 |         |\n+-------------------+-----------------------------------+---------+\n| ``\\\'``            | Single quote (``\'``)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\"``            | Double quote (``"``)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\a``            | ASCII Bell (BEL)                  |         |\n+-------------------+-----------------------------------+---------+\n| ``\\b``            | ASCII Backspace (BS)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\f``            | ASCII Formfeed (FF)               |         |\n+-------------------+-----------------------------------+---------+\n| ``\\n``            | ASCII Linefeed (LF)               |         |\n+-------------------+-----------------------------------+---------+\n| ``\\r``            | ASCII Carriage Return (CR)        |         |\n+-------------------+-----------------------------------+---------+\n| ``\\t``            | ASCII Horizontal Tab (TAB)        |         |\n+-------------------+-----------------------------------+---------+\n| ``\\v``            | ASCII Vertical Tab (VT)           |         |\n+-------------------+-----------------------------------+---------+\n| ``\\ooo``          | Character with octal value *ooo*  | (1,3)   |\n+-------------------+-----------------------------------+---------+\n| ``\\xhh``          | Character with hex value *hh*     | (2,3)   |\n+-------------------+-----------------------------------+---------+\n\nEscape sequences only recognized in string literals are:\n\n+-------------------+-----------------------------------+---------+\n| Escape Sequence   | Meaning                           | Notes   |\n+===================+===================================+=========+\n| ``\\N{name}``      | Character named *name* in the     |         |\n|                   | Unicode database                  |         |\n+-------------------+-----------------------------------+---------+\n| ``\\uxxxx``        | Character with 16-bit hex value   | (4)     |\n|                   | *xxxx*                            |         |\n+-------------------+-----------------------------------+---------+\n| ``\\Uxxxxxxxx``    | Character with 32-bit hex value   | (5)     |\n|                   | *xxxxxxxx*                        |         |\n+-------------------+-----------------------------------+---------+\n\nNotes:\n\n1. As in Standard C, up to three octal digits are accepted.\n\n2. Unlike in Standard C, at most two hex digits are accepted.\n\n3. In a bytes literal, hexadecimal and octal escapes denote the byte\n   with the given value. In a string literal, these escapes denote a\n   Unicode character with the given value.\n\n4. Individual code units which form parts of a surrogate pair can be\n   encoded using this escape sequence. Unlike in Standard C, exactly\n   two hex digits are required.\n\n5. Any Unicode character can be encoded this way, but characters\n   outside the Basic Multilingual Plane (BMP) will be encoded using a\n   surrogate pair if Python is compiled to use 16-bit code units (the\n   default).  Individual code units which form parts of a surrogate\n   pair can be encoded using this escape sequence.\n\nUnlike Standard C, all unrecognized escape sequences are left in the\nstring unchanged, i.e., *the backslash is left in the string*.  (This\nbehavior is useful when debugging: if an escape sequence is mistyped,\nthe resulting output is more easily recognized as broken.)  It is also\nimportant to note that the escape sequences only recognized in string\nliterals fall into the category of unrecognized escapes for bytes\nliterals.\n\nEven in a raw string, string quotes can be escaped with a backslash,\nbut the backslash remains in the string; for example, ``r"\\""`` is a\nvalid string literal consisting of two characters: a backslash and a\ndouble quote; ``r"\\"`` is not a valid string literal (even a raw\nstring cannot end in an odd number of backslashes).  Specifically, *a\nraw string cannot end in a single backslash* (since the backslash\nwould escape the following quote character).  Note also that a single\nbackslash followed by a newline is interpreted as those two characters\nas part of the string, *not* as a line continuation.\n',
- 'subscriptions': '\nSubscriptions\n*************\n\nA subscription selects an item of a sequence (string, tuple or list)\nor mapping (dictionary) object:\n\n   subscription ::= primary "[" expression_list "]"\n\nThe primary must evaluate to an object that supports subscription,\ne.g. a list or dictionary.  User-defined objects can support\nsubscription by defining a ``__getitem__()`` method.\n\nFor built-in objects, there are two types of objects that support\nsubscription:\n\nIf the primary is a mapping, the expression list must evaluate to an\nobject whose value is one of the keys of the mapping, and the\nsubscription selects the value in the mapping that corresponds to that\nkey.  (The expression list is a tuple except if it has exactly one\nitem.)\n\nIf the primary is a sequence, the expression (list) must evaluate to\nan integer. If this value is negative, the length of the sequence is\nadded to it (so that, e.g., ``x[-1]`` selects the last item of ``x``.)\nThe resulting value must be a nonnegative integer less than the number\nof items in the sequence, and the subscription selects the item whose\nindex is that value (counting from zero).\n\nA string\'s items are characters.  A character is not a separate data\ntype but a string of exactly one character.\n',
+ 'specialattrs': "\nSpecial Attributes\n******************\n\nThe implementation adds a few special read-only attributes to several\nobject types, where they are relevant.  Some of these are not reported\nby the ``dir()`` built-in function.\n\nobject.__dict__\n\n   A dictionary or other mapping object used to store an object's\n   (writable) attributes.\n\ninstance.__class__\n\n   The class to which a class instance belongs.\n\nclass.__bases__\n\n   The tuple of base classes of a class object.\n\nclass.__name__\n\n   The name of the class or type.\n\nThe following attributes are only supported by *new-style class*es.\n\nclass.__mro__\n\n   This attribute is a tuple of classes that are considered when\n   looking for base classes during method resolution.\n\nclass.mro()\n\n   This method can be overridden by a metaclass to customize the\n   method resolution order for its instances.  It is called at class\n   instantiation, and its result is stored in ``__mro__``.\n\nclass.__subclasses__()\n\n   Each new-style class keeps a list of weak references to its\n   immediate subclasses.  This method returns a list of all those\n   references still alive. Example:\n\n      >>> int.__subclasses__()\n      [<type 'bool'>]\n\n-[ Footnotes ]-\n\n[1] Additional information on these special methods may be found in\n    the Python Reference Manual (*Basic customization*).\n\n[2] As a consequence, the list ``[1, 2]`` is considered equal to\n    ``[1.0, 2.0]``, and similarly for tuples.\n\n[3] They must have since the parser can't tell the type of the\n    operands.\n\n[4] To format only a tuple you should therefore provide a singleton\n    tuple whose only element is the tuple to be formatted.\n",
+ 'specialnames': '\nSpecial method names\n********************\n\nA class can implement certain operations that are invoked by special\nsyntax (such as arithmetic operations or subscripting and slicing) by\ndefining methods with special names. This is Python\'s approach to\n*operator overloading*, allowing classes to define their own behavior\nwith respect to language operators.  For instance, if a class defines\na method named ``__getitem__()``, and ``x`` is an instance of this\nclass, then ``x[i]`` is roughly equivalent to ``type(x).__getitem__(x,\ni)``.  Except where mentioned, attempts to execute an operation raise\nan exception when no appropriate method is defined (typically\n``AttributeError`` or ``TypeError``).\n\nWhen implementing a class that emulates any built-in type, it is\nimportant that the emulation only be implemented to the degree that it\nmakes sense for the object being modelled.  For example, some\nsequences may work well with retrieval of individual elements, but\nextracting a slice may not make sense.  (One example of this is the\n``NodeList`` interface in the W3C\'s Document Object Model.)\n\n\nBasic customization\n===================\n\nobject.__new__(cls[, ...])\n\n   Called to create a new instance of class *cls*.  ``__new__()`` is a\n   static method (special-cased so you need not declare it as such)\n   that takes the class of which an instance was requested as its\n   first argument.  The remaining arguments are those passed to the\n   object constructor expression (the call to the class).  The return\n   value of ``__new__()`` should be the new object instance (usually\n   an instance of *cls*).\n\n   Typical implementations create a new instance of the class by\n   invoking the superclass\'s ``__new__()`` method using\n   ``super(currentclass, cls).__new__(cls[, ...])`` with appropriate\n   arguments and then modifying the newly-created instance as\n   necessary before returning it.\n\n   If ``__new__()`` returns an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will be invoked like\n   ``__init__(self[, ...])``, where *self* is the new instance and the\n   remaining arguments are the same as were passed to ``__new__()``.\n\n   If ``__new__()`` does not return an instance of *cls*, then the new\n   instance\'s ``__init__()`` method will not be invoked.\n\n   ``__new__()`` is intended mainly to allow subclasses of immutable\n   types (like int, str, or tuple) to customize instance creation.  It\n   is also commonly overridden in custom metaclasses in order to\n   customize class creation.\n\nobject.__init__(self[, ...])\n\n   Called when the instance is created.  The arguments are those\n   passed to the class constructor expression.  If a base class has an\n   ``__init__()`` method, the derived class\'s ``__init__()`` method,\n   if any, must explicitly call it to ensure proper initialization of\n   the base class part of the instance; for example:\n   ``BaseClass.__init__(self, [args...])``.  As a special constraint\n   on constructors, no value may be returned; doing so will cause a\n   ``TypeError`` to be raised at runtime.\n\nobject.__del__(self)\n\n   Called when the instance is about to be destroyed.  This is also\n   called a destructor.  If a base class has a ``__del__()`` method,\n   the derived class\'s ``__del__()`` method, if any, must explicitly\n   call it to ensure proper deletion of the base class part of the\n   instance.  Note that it is possible (though not recommended!) for\n   the ``__del__()`` method to postpone destruction of the instance by\n   creating a new reference to it.  It may then be called at a later\n   time when this new reference is deleted.  It is not guaranteed that\n   ``__del__()`` methods are called for objects that still exist when\n   the interpreter exits.\n\n   Note: ``del x`` doesn\'t directly call ``x.__del__()`` --- the former\n     decrements the reference count for ``x`` by one, and the latter\n     is only called when ``x``\'s reference count reaches zero.  Some\n     common situations that may prevent the reference count of an\n     object from going to zero include: circular references between\n     objects (e.g., a doubly-linked list or a tree data structure with\n     parent and child pointers); a reference to the object on the\n     stack frame of a function that caught an exception (the traceback\n     stored in ``sys.exc_info()[2]`` keeps the stack frame alive); or\n     a reference to the object on the stack frame that raised an\n     unhandled exception in interactive mode (the traceback stored in\n     ``sys.last_traceback`` keeps the stack frame alive).  The first\n     situation can only be remedied by explicitly breaking the cycles;\n     the latter two situations can be resolved by storing ``None`` in\n     ``sys.last_traceback``. Circular references which are garbage are\n     detected when the option cycle detector is enabled (it\'s on by\n     default), but can only be cleaned up if there are no Python-\n     level ``__del__()`` methods involved. Refer to the documentation\n     for the ``gc`` module for more information about how\n     ``__del__()`` methods are handled by the cycle detector,\n     particularly the description of the ``garbage`` value.\n\n   Warning: Due to the precarious circumstances under which ``__del__()``\n     methods are invoked, exceptions that occur during their execution\n     are ignored, and a warning is printed to ``sys.stderr`` instead.\n     Also, when ``__del__()`` is invoked in response to a module being\n     deleted (e.g., when execution of the program is done), other\n     globals referenced by the ``__del__()`` method may already have\n     been deleted or in the process of being torn down (e.g. the\n     import machinery shutting down).  For this reason, ``__del__()``\n     methods should do the absolute minimum needed to maintain\n     external invariants.  Starting with version 1.5, Python\n     guarantees that globals whose name begins with a single\n     underscore are deleted from their module before other globals are\n     deleted; if no other references to such globals exist, this may\n     help in assuring that imported modules are still available at the\n     time when the ``__del__()`` method is called.\n\nobject.__repr__(self)\n\n   Called by the ``repr()`` built-in function to compute the\n   "official" string representation of an object.  If at all possible,\n   this should look like a valid Python expression that could be used\n   to recreate an object with the same value (given an appropriate\n   environment).  If this is not possible, a string of the form\n   ``<...some useful description...>`` should be returned. The return\n   value must be a string object. If a class defines ``__repr__()``\n   but not ``__str__()``, then ``__repr__()`` is also used when an\n   "informal" string representation of instances of that class is\n   required.\n\n   This is typically used for debugging, so it is important that the\n   representation is information-rich and unambiguous.\n\nobject.__str__(self)\n\n   Called by the ``str()`` built-in function and by the ``print()``\n   function to compute the "informal" string representation of an\n   object.  This differs from ``__repr__()`` in that it does not have\n   to be a valid Python expression: a more convenient or concise\n   representation may be used instead. The return value must be a\n   string object.\n\nobject.__format__(self, format_spec)\n\n   Called by the ``format()`` built-in function (and by extension, the\n   ``format()`` method of class ``str``) to produce a "formatted"\n   string representation of an object. The ``format_spec`` argument is\n   a string that contains a description of the formatting options\n   desired. The interpretation of the ``format_spec`` argument is up\n   to the type implementing ``__format__()``, however most classes\n   will either delegate formatting to one of the built-in types, or\n   use a similar formatting option syntax.\n\n   See *Format Specification Mini-Language* for a description of the\n   standard formatting syntax.\n\n   The return value must be a string object.\n\nobject.__lt__(self, other)\nobject.__le__(self, other)\nobject.__eq__(self, other)\nobject.__ne__(self, other)\nobject.__gt__(self, other)\nobject.__ge__(self, other)\n\n   These are the so-called "rich comparison" methods. The\n   correspondence between operator symbols and method names is as\n   follows: ``x<y`` calls ``x.__lt__(y)``, ``x<=y`` calls\n   ``x.__le__(y)``, ``x==y`` calls ``x.__eq__(y)``, ``x!=y`` calls\n   ``x.__ne__(y)``, ``x>y`` calls ``x.__gt__(y)``, and ``x>=y`` calls\n   ``x.__ge__(y)``.\n\n   A rich comparison method may return the singleton\n   ``NotImplemented`` if it does not implement the operation for a\n   given pair of arguments. By convention, ``False`` and ``True`` are\n   returned for a successful comparison. However, these methods can\n   return any value, so if the comparison operator is used in a\n   Boolean context (e.g., in the condition of an ``if`` statement),\n   Python will call ``bool()`` on the value to determine if the result\n   is true or false.\n\n   There are no implied relationships among the comparison operators.\n   The truth of ``x==y`` does not imply that ``x!=y`` is false.\n   Accordingly, when defining ``__eq__()``, one should also define\n   ``__ne__()`` so that the operators will behave as expected.  See\n   the paragraph on ``__hash__()`` for some important notes on\n   creating *hashable* objects which support custom comparison\n   operations and are usable as dictionary keys.\n\n   There are no swapped-argument versions of these methods (to be used\n   when the left argument does not support the operation but the right\n   argument does); rather, ``__lt__()`` and ``__gt__()`` are each\n   other\'s reflection, ``__le__()`` and ``__ge__()`` are each other\'s\n   reflection, and ``__eq__()`` and ``__ne__()`` are their own\n   reflection.\n\n   Arguments to rich comparison methods are never coerced.\n\n   To automatically generate ordering operations from a single root\n   operation, see ``functools.total_ordering()``.\n\nobject.__hash__(self)\n\n   Called by built-in function ``hash()`` and for operations on\n   members of hashed collections including ``set``, ``frozenset``, and\n   ``dict``.  ``__hash__()`` should return an integer.  The only\n   required property is that objects which compare equal have the same\n   hash value; it is advised to somehow mix together (e.g. using\n   exclusive or) the hash values for the components of the object that\n   also play a part in comparison of objects.\n\n   If a class does not define an ``__eq__()`` method it should not\n   define a ``__hash__()`` operation either; if it defines\n   ``__eq__()`` but not ``__hash__()``, its instances will not be\n   usable as items in hashable collections.  If a class defines\n   mutable objects and implements an ``__eq__()`` method, it should\n   not implement ``__hash__()``, since the implementation of hashable\n   collections requires that a key\'s hash value is immutable (if the\n   object\'s hash value changes, it will be in the wrong hash bucket).\n\n   User-defined classes have ``__eq__()`` and ``__hash__()`` methods\n   by default; with them, all objects compare unequal (except with\n   themselves) and ``x.__hash__()`` returns ``id(x)``.\n\n   Classes which inherit a ``__hash__()`` method from a parent class\n   but change the meaning of ``__eq__()`` such that the hash value\n   returned is no longer appropriate (e.g. by switching to a value-\n   based concept of equality instead of the default identity based\n   equality) can explicitly flag themselves as being unhashable by\n   setting ``__hash__ = None`` in the class definition. Doing so means\n   that not only will instances of the class raise an appropriate\n   ``TypeError`` when a program attempts to retrieve their hash value,\n   but they will also be correctly identified as unhashable when\n   checking ``isinstance(obj, collections.Hashable)`` (unlike classes\n   which define their own ``__hash__()`` to explicitly raise\n   ``TypeError``).\n\n   If a class that overrides ``__eq__()`` needs to retain the\n   implementation of ``__hash__()`` from a parent class, the\n   interpreter must be told this explicitly by setting ``__hash__ =\n   <ParentClass>.__hash__``. Otherwise the inheritance of\n   ``__hash__()`` will be blocked, just as if ``__hash__`` had been\n   explicitly set to ``None``.\n\nobject.__bool__(self)\n\n   Called to implement truth value testing and the built-in operation\n   ``bool()``; should return ``False`` or ``True``.  When this method\n   is not defined, ``__len__()`` is called, if it is defined, and the\n   object is considered true if its result is nonzero.  If a class\n   defines neither ``__len__()`` nor ``__bool__()``, all its instances\n   are considered true.\n\n\nCustomizing attribute access\n============================\n\nThe following methods can be defined to customize the meaning of\nattribute access (use of, assignment to, or deletion of ``x.name``)\nfor class instances.\n\nobject.__getattr__(self, name)\n\n   Called when an attribute lookup has not found the attribute in the\n   usual places (i.e. it is not an instance attribute nor is it found\n   in the class tree for ``self``).  ``name`` is the attribute name.\n   This method should return the (computed) attribute value or raise\n   an ``AttributeError`` exception.\n\n   Note that if the attribute is found through the normal mechanism,\n   ``__getattr__()`` is not called.  (This is an intentional asymmetry\n   between ``__getattr__()`` and ``__setattr__()``.) This is done both\n   for efficiency reasons and because otherwise ``__getattr__()``\n   would have no way to access other attributes of the instance.  Note\n   that at least for instance variables, you can fake total control by\n   not inserting any values in the instance attribute dictionary (but\n   instead inserting them in another object).  See the\n   ``__getattribute__()`` method below for a way to actually get total\n   control over attribute access.\n\nobject.__getattribute__(self, name)\n\n   Called unconditionally to implement attribute accesses for\n   instances of the class. If the class also defines\n   ``__getattr__()``, the latter will not be called unless\n   ``__getattribute__()`` either calls it explicitly or raises an\n   ``AttributeError``. This method should return the (computed)\n   attribute value or raise an ``AttributeError`` exception. In order\n   to avoid infinite recursion in this method, its implementation\n   should always call the base class method with the same name to\n   access any attributes it needs, for example,\n   ``object.__getattribute__(self, name)``.\n\n   Note: This method may still be bypassed when looking up special methods\n     as the result of implicit invocation via language syntax or\n     built-in functions. See *Special method lookup*.\n\nobject.__setattr__(self, name, value)\n\n   Called when an attribute assignment is attempted.  This is called\n   instead of the normal mechanism (i.e. store the value in the\n   instance dictionary). *name* is the attribute name, *value* is the\n   value to be assigned to it.\n\n   If ``__setattr__()`` wants to assign to an instance attribute, it\n   should call the base class method with the same name, for example,\n   ``object.__setattr__(self, name, value)``.\n\nobject.__delattr__(self, name)\n\n   Like ``__setattr__()`` but for attribute deletion instead of\n   assignment.  This should only be implemented if ``del obj.name`` is\n   meaningful for the object.\n\nobject.__dir__(self)\n\n   Called when ``dir()`` is called on the object.  A list must be\n   returned.\n\n\nImplementing Descriptors\n------------------------\n\nThe following methods only apply when an instance of the class\ncontaining the method (a so-called *descriptor* class) appears in the\nclass dictionary of another class, known as the *owner* class.  In the\nexamples below, "the attribute" refers to the attribute whose name is\nthe key of the property in the owner class\' ``__dict__``.\n\nobject.__get__(self, instance, owner)\n\n   Called to get the attribute of the owner class (class attribute\n   access) or of an instance of that class (instance attribute\n   access). *owner* is always the owner class, while *instance* is the\n   instance that the attribute was accessed through, or ``None`` when\n   the attribute is accessed through the *owner*.  This method should\n   return the (computed) attribute value or raise an\n   ``AttributeError`` exception.\n\nobject.__set__(self, instance, value)\n\n   Called to set the attribute on an instance *instance* of the owner\n   class to a new value, *value*.\n\nobject.__delete__(self, instance)\n\n   Called to delete the attribute on an instance *instance* of the\n   owner class.\n\n\nInvoking Descriptors\n--------------------\n\nIn general, a descriptor is an object attribute with "binding\nbehavior", one whose attribute access has been overridden by methods\nin the descriptor protocol:  ``__get__()``, ``__set__()``, and\n``__delete__()``. If any of those methods are defined for an object,\nit is said to be a descriptor.\n\nThe default behavior for attribute access is to get, set, or delete\nthe attribute from an object\'s dictionary. For instance, ``a.x`` has a\nlookup chain starting with ``a.__dict__[\'x\']``, then\n``type(a).__dict__[\'x\']``, and continuing through the base classes of\n``type(a)`` excluding metaclasses.\n\nHowever, if the looked-up value is an object defining one of the\ndescriptor methods, then Python may override the default behavior and\ninvoke the descriptor method instead.  Where this occurs in the\nprecedence chain depends on which descriptor methods were defined and\nhow they were called.\n\nThe starting point for descriptor invocation is a binding, ``a.x``.\nHow the arguments are assembled depends on ``a``:\n\nDirect Call\n   The simplest and least common call is when user code directly\n   invokes a descriptor method:    ``x.__get__(a)``.\n\nInstance Binding\n   If binding to an object instance, ``a.x`` is transformed into the\n   call: ``type(a).__dict__[\'x\'].__get__(a, type(a))``.\n\nClass Binding\n   If binding to a class, ``A.x`` is transformed into the call:\n   ``A.__dict__[\'x\'].__get__(None, A)``.\n\nSuper Binding\n   If ``a`` is an instance of ``super``, then the binding ``super(B,\n   obj).m()`` searches ``obj.__class__.__mro__`` for the base class\n   ``A`` immediately preceding ``B`` and then invokes the descriptor\n   with the call: ``A.__dict__[\'m\'].__get__(obj, A)``.\n\nFor instance bindings, the precedence of descriptor invocation depends\non the which descriptor methods are defined.  A descriptor can define\nany combination of ``__get__()``, ``__set__()`` and ``__delete__()``.\nIf it does not define ``__get__()``, then accessing the attribute will\nreturn the descriptor object itself unless there is a value in the\nobject\'s instance dictionary.  If the descriptor defines ``__set__()``\nand/or ``__delete__()``, it is a data descriptor; if it defines\nneither, it is a non-data descriptor.  Normally, data descriptors\ndefine both ``__get__()`` and ``__set__()``, while non-data\ndescriptors have just the ``__get__()`` method.  Data descriptors with\n``__set__()`` and ``__get__()`` defined always override a redefinition\nin an instance dictionary.  In contrast, non-data descriptors can be\noverridden by instances.\n\nPython methods (including ``staticmethod()`` and ``classmethod()``)\nare implemented as non-data descriptors.  Accordingly, instances can\nredefine and override methods.  This allows individual instances to\nacquire behaviors that differ from other instances of the same class.\n\nThe ``property()`` function is implemented as a data descriptor.\nAccordingly, instances cannot override the behavior of a property.\n\n\n__slots__\n---------\n\nBy default, instances of classes have a dictionary for attribute\nstorage.  This wastes space for objects having very few instance\nvariables.  The space consumption can become acute when creating large\nnumbers of instances.\n\nThe default can be overridden by defining *__slots__* in a class\ndefinition. The *__slots__* declaration takes a sequence of instance\nvariables and reserves just enough space in each instance to hold a\nvalue for each variable.  Space is saved because *__dict__* is not\ncreated for each instance.\n\nobject.__slots__\n\n   This class variable can be assigned a string, iterable, or sequence\n   of strings with variable names used by instances.  If defined in a\n   class, *__slots__* reserves space for the declared variables and\n   prevents the automatic creation of *__dict__* and *__weakref__* for\n   each instance.\n\n\nNotes on using *__slots__*\n~~~~~~~~~~~~~~~~~~~~~~~~~~\n\n* When inheriting from a class without *__slots__*, the *__dict__*\n  attribute of that class will always be accessible, so a *__slots__*\n  definition in the subclass is meaningless.\n\n* Without a *__dict__* variable, instances cannot be assigned new\n  variables not listed in the *__slots__* definition.  Attempts to\n  assign to an unlisted variable name raises ``AttributeError``. If\n  dynamic assignment of new variables is desired, then add\n  ``\'__dict__\'`` to the sequence of strings in the *__slots__*\n  declaration.\n\n* Without a *__weakref__* variable for each instance, classes defining\n  *__slots__* do not support weak references to its instances. If weak\n  reference support is needed, then add ``\'__weakref__\'`` to the\n  sequence of strings in the *__slots__* declaration.\n\n* *__slots__* are implemented at the class level by creating\n  descriptors (*Implementing Descriptors*) for each variable name.  As\n  a result, class attributes cannot be used to set default values for\n  instance variables defined by *__slots__*; otherwise, the class\n  attribute would overwrite the descriptor assignment.\n\n* The action of a *__slots__* declaration is limited to the class\n  where it is defined.  As a result, subclasses will have a *__dict__*\n  unless they also define *__slots__* (which must only contain names\n  of any *additional* slots).\n\n* If a class defines a slot also defined in a base class, the instance\n  variable defined by the base class slot is inaccessible (except by\n  retrieving its descriptor directly from the base class). This\n  renders the meaning of the program undefined.  In the future, a\n  check may be added to prevent this.\n\n* Nonempty *__slots__* does not work for classes derived from\n  "variable-length" built-in types such as ``int``, ``str`` and\n  ``tuple``.\n\n* Any non-string iterable may be assigned to *__slots__*. Mappings may\n  also be used; however, in the future, special meaning may be\n  assigned to the values corresponding to each key.\n\n* *__class__* assignment works only if both classes have the same\n  *__slots__*.\n\n\nCustomizing class creation\n==========================\n\nBy default, classes are constructed using ``type()``. A class\ndefinition is read into a separate namespace and the value of class\nname is bound to the result of ``type(name, bases, dict)``.\n\nWhen the class definition is read, if a callable ``metaclass`` keyword\nargument is passed after the bases in the class definition, the\ncallable given will be called instead of ``type()``.  If other keyword\narguments are passed, they will also be passed to the metaclass.  This\nallows classes or functions to be written which monitor or alter the\nclass creation process:\n\n* Modifying the class dictionary prior to the class being created.\n\n* Returning an instance of another class -- essentially performing the\n  role of a factory function.\n\nThese steps will have to be performed in the metaclass\'s ``__new__()``\nmethod -- ``type.__new__()`` can then be called from this method to\ncreate a class with different properties.  This example adds a new\nelement to the class dictionary before creating the class:\n\n   class metacls(type):\n       def __new__(mcs, name, bases, dict):\n           dict[\'foo\'] = \'metacls was here\'\n           return type.__new__(mcs, name, bases, dict)\n\nYou can of course also override other class methods (or add new\nmethods); for example defining a custom ``__call__()`` method in the\nmetaclass allows custom behavior when the class is called, e.g. not\nalways creating a new instance.\n\nIf the metaclass has a ``__prepare__()`` attribute (usually\nimplemented as a class or static method), it is called before the\nclass body is evaluated with the name of the class and a tuple of its\nbases for arguments.  It should return an object that supports the\nmapping interface that will be used to store the namespace of the\nclass.  The default is a plain dictionary.  This could be used, for\nexample, to keep track of the order that class attributes are declared\nin by returning an ordered dictionary.\n\nThe appropriate metaclass is determined by the following precedence\nrules:\n\n* If the ``metaclass`` keyword argument is passed with the bases, it\n  is used.\n\n* Otherwise, if there is at least one base class, its metaclass is\n  used.\n\n* Otherwise, the default metaclass (``type``) is used.\n\nThe potential uses for metaclasses are boundless. Some ideas that have\nbeen explored including logging, interface checking, automatic\ndelegation, automatic property creation, proxies, frameworks, and\nautomatic resource locking/synchronization.\n\nHere is an example of a metaclass that uses an\n``collections.OrderedDict`` to remember the order that class members\nwere defined:\n\n   class OrderedClass(type):\n\n        @classmethod\n        def __prepare__(metacls, name, bases, **kwds):\n           return collections.OrderedDict()\n\n        def __new__(cls, name, bases, classdict):\n           result = type.__new__(cls, name, bases, dict(classdict))\n           result.members = tuple(classdict)\n           return result\n\n   class A(metaclass=OrderedClass):\n       def one(self): pass\n       def two(self): pass\n       def three(self): pass\n       def four(self): pass\n\n   >>> A.members\n   (\'__module__\', \'one\', \'two\', \'three\', \'four\')\n\nWhen the class definition for *A* gets executed, the process begins\nwith calling the metaclass\'s ``__prepare__()`` method which returns an\nempty ``collections.OrderedDict``.  That mapping records the methods\nand attributes of *A* as they are defined within the body of the class\nstatement. Once those definitions are executed, the ordered dictionary\nis fully populated and the metaclass\'s ``__new__()`` method gets\ninvoked.  That method builds the new type and it saves the ordered\ndictionary keys in an attribute called ``members``.\n\n\nCustomizing instance and subclass checks\n========================================\n\nThe following methods are used to override the default behavior of the\n``isinstance()`` and ``issubclass()`` built-in functions.\n\nIn particular, the metaclass ``abc.ABCMeta`` implements these methods\nin order to allow the addition of Abstract Base Classes (ABCs) as\n"virtual base classes" to any class or type (including built-in\ntypes), including other ABCs.\n\nclass.__instancecheck__(self, instance)\n\n   Return true if *instance* should be considered a (direct or\n   indirect) instance of *class*. If defined, called to implement\n   ``isinstance(instance, class)``.\n\nclass.__subclasscheck__(self, subclass)\n\n   Return true if *subclass* should be considered a (direct or\n   indirect) subclass of *class*.  If defined, called to implement\n   ``issubclass(subclass, class)``.\n\nNote that these methods are looked up on the type (metaclass) of a\nclass.  They cannot be defined as class methods in the actual class.\nThis is consistent with the lookup of special methods that are called\non instances, only in this case the instance is itself a class.\n\nSee also:\n\n   **PEP 3119** - Introducing Abstract Base Classes\n      Includes the specification for customizing ``isinstance()`` and\n      ``issubclass()`` behavior through ``__instancecheck__()`` and\n      ``__subclasscheck__()``, with motivation for this functionality\n      in the context of adding Abstract Base Classes (see the ``abc``\n      module) to the language.\n\n\nEmulating callable objects\n==========================\n\nobject.__call__(self[, args...])\n\n   Called when the instance is "called" as a function; if this method\n   is defined, ``x(arg1, arg2, ...)`` is a shorthand for\n   ``x.__call__(arg1, arg2, ...)``.\n\n\nEmulating container types\n=========================\n\nThe following methods can be defined to implement container objects.\nContainers usually are sequences (such as lists or tuples) or mappings\n(like dictionaries), but can represent other containers as well.  The\nfirst set of methods is used either to emulate a sequence or to\nemulate a mapping; the difference is that for a sequence, the\nallowable keys should be the integers *k* for which ``0 <= k < N``\nwhere *N* is the length of the sequence, or slice objects, which\ndefine a range of items.  It is also recommended that mappings provide\nthe methods ``keys()``, ``values()``, ``items()``, ``get()``,\n``clear()``, ``setdefault()``, ``pop()``, ``popitem()``, ``copy()``,\nand ``update()`` behaving similar to those for Python\'s standard\ndictionary objects.  The ``collections`` module provides a\n``MutableMapping`` abstract base class to help create those methods\nfrom a base set of ``__getitem__()``, ``__setitem__()``,\n``__delitem__()``, and ``keys()``. Mutable sequences should provide\nmethods ``append()``, ``count()``, ``index()``, ``extend()``,\n``insert()``, ``pop()``, ``remove()``, ``reverse()`` and ``sort()``,\nlike Python standard list objects.  Finally, sequence types should\nimplement addition (meaning concatenation) and multiplication (meaning\nrepetition) by defining the methods ``__add__()``, ``__radd__()``,\n``__iadd__()``, ``__mul__()``, ``__rmul__()`` and ``__imul__()``\ndescribed below; they should not define other numerical operators.  It\nis recommended that both mappings and sequences implement the\n``__contains__()`` method to allow efficient use of the ``in``\noperator; for mappings, ``in`` should search the mapping\'s keys; for\nsequences, it should search through the values.  It is further\nrecommended that both mappings and sequences implement the\n``__iter__()`` method to allow efficient iteration through the\ncontainer; for mappings, ``__iter__()`` should be the same as\n``keys()``; for sequences, it should iterate through the values.\n\nobject.__len__(self)\n\n   Called to implement the built-in function ``len()``.  Should return\n   the length of the object, an integer ``>=`` 0.  Also, an object\n   that doesn\'t define a ``__bool__()`` method and whose ``__len__()``\n   method returns zero is considered to be false in a Boolean context.\n\nNote: Slicing is done exclusively with the following three methods.  A\n  call like\n\n     a[1:2] = b\n\n  is translated to\n\n     a[slice(1, 2, None)] = b\n\n  and so forth.  Missing slice items are always filled in with\n  ``None``.\n\nobject.__getitem__(self, key)\n\n   Called to implement evaluation of ``self[key]``. For sequence\n   types, the accepted keys should be integers and slice objects.\n   Note that the special interpretation of negative indexes (if the\n   class wishes to emulate a sequence type) is up to the\n   ``__getitem__()`` method. If *key* is of an inappropriate type,\n   ``TypeError`` may be raised; if of a value outside the set of\n   indexes for the sequence (after any special interpretation of\n   negative values), ``IndexError`` should be raised. For mapping\n   types, if *key* is missing (not in the container), ``KeyError``\n   should be raised.\n\n   Note: ``for`` loops expect that an ``IndexError`` will be raised for\n     illegal indexes to allow proper detection of the end of the\n     sequence.\n\nobject.__setitem__(self, key, value)\n\n   Called to implement assignment to ``self[key]``.  Same note as for\n   ``__getitem__()``.  This should only be implemented for mappings if\n   the objects support changes to the values for keys, or if new keys\n   can be added, or for sequences if elements can be replaced.  The\n   same exceptions should be raised for improper *key* values as for\n   the ``__getitem__()`` method.\n\nobject.__delitem__(self, key)\n\n   Called to implement deletion of ``self[key]``.  Same note as for\n   ``__getitem__()``.  This should only be implemented for mappings if\n   the objects support removal of keys, or for sequences if elements\n   can be removed from the sequence.  The same exceptions should be\n   raised for improper *key* values as for the ``__getitem__()``\n   method.\n\nobject.__iter__(self)\n\n   This method is called when an iterator is required for a container.\n   This method should return a new iterator object that can iterate\n   over all the objects in the container.  For mappings, it should\n   iterate over the keys of the container, and should also be made\n   available as the method ``keys()``.\n\n   Iterator objects also need to implement this method; they are\n   required to return themselves.  For more information on iterator\n   objects, see *Iterator Types*.\n\nobject.__reversed__(self)\n\n   Called (if present) by the ``reversed()`` built-in to implement\n   reverse iteration.  It should return a new iterator object that\n   iterates over all the objects in the container in reverse order.\n\n   If the ``__reversed__()`` method is not provided, the\n   ``reversed()`` built-in will fall back to using the sequence\n   protocol (``__len__()`` and ``__getitem__()``).  Objects that\n   support the sequence protocol should only provide\n   ``__reversed__()`` if they can provide an implementation that is\n   more efficient than the one provided by ``reversed()``.\n\nThe membership test operators (``in`` and ``not in``) are normally\nimplemented as an iteration through a sequence.  However, container\nobjects can supply the following special method with a more efficient\nimplementation, which also does not require the object be a sequence.\n\nobject.__contains__(self, item)\n\n   Called to implement membership test operators.  Should return true\n   if *item* is in *self*, false otherwise.  For mapping objects, this\n   should consider the keys of the mapping rather than the values or\n   the key-item pairs.\n\n   For objects that don\'t define ``__contains__()``, the membership\n   test first tries iteration via ``__iter__()``, then the old\n   sequence iteration protocol via ``__getitem__()``, see *this\n   section in the language reference*.\n\n\nEmulating numeric types\n=======================\n\nThe following methods can be defined to emulate numeric objects.\nMethods corresponding to operations that are not supported by the\nparticular kind of number implemented (e.g., bitwise operations for\nnon-integral numbers) should be left undefined.\n\nobject.__add__(self, other)\nobject.__sub__(self, other)\nobject.__mul__(self, other)\nobject.__truediv__(self, other)\nobject.__floordiv__(self, other)\nobject.__mod__(self, other)\nobject.__divmod__(self, other)\nobject.__pow__(self, other[, modulo])\nobject.__lshift__(self, other)\nobject.__rshift__(self, other)\nobject.__and__(self, other)\nobject.__xor__(self, other)\nobject.__or__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations (``+``, ``-``, ``*``, ``/``, ``//``, ``%``,\n   ``divmod()``, ``pow()``, ``**``, ``<<``, ``>>``, ``&``, ``^``,\n   ``|``).  For instance, to evaluate the expression ``x + y``, where\n   *x* is an instance of a class that has an ``__add__()`` method,\n   ``x.__add__(y)`` is called.  The ``__divmod__()`` method should be\n   the equivalent to using ``__floordiv__()`` and ``__mod__()``; it\n   should not be related to ``__truediv__()``.  Note that\n   ``__pow__()`` should be defined to accept an optional third\n   argument if the ternary version of the built-in ``pow()`` function\n   is to be supported.\n\n   If one of those methods does not support the operation with the\n   supplied arguments, it should return ``NotImplemented``.\n\nobject.__radd__(self, other)\nobject.__rsub__(self, other)\nobject.__rmul__(self, other)\nobject.__rtruediv__(self, other)\nobject.__rfloordiv__(self, other)\nobject.__rmod__(self, other)\nobject.__rdivmod__(self, other)\nobject.__rpow__(self, other)\nobject.__rlshift__(self, other)\nobject.__rrshift__(self, other)\nobject.__rand__(self, other)\nobject.__rxor__(self, other)\nobject.__ror__(self, other)\n\n   These methods are called to implement the binary arithmetic\n   operations (``+``, ``-``, ``*``, ``/``, ``//``, ``%``,\n   ``divmod()``, ``pow()``, ``**``, ``<<``, ``>>``, ``&``, ``^``,\n   ``|``) with reflected (swapped) operands. These functions are only\n   called if the left operand does not support the corresponding\n   operation and the operands are of different types. [2]  For\n   instance, to evaluate the expression ``x - y``, where *y* is an\n   instance of a class that has an ``__rsub__()`` method,\n   ``y.__rsub__(x)`` is called if ``x.__sub__(y)`` returns\n   *NotImplemented*.\n\n   Note that ternary ``pow()`` will not try calling ``__rpow__()``\n   (the coercion rules would become too complicated).\n\n   Note: If the right operand\'s type is a subclass of the left operand\'s\n     type and that subclass provides the reflected method for the\n     operation, this method will be called before the left operand\'s\n     non-reflected method.  This behavior allows subclasses to\n     override their ancestors\' operations.\n\nobject.__iadd__(self, other)\nobject.__isub__(self, other)\nobject.__imul__(self, other)\nobject.__itruediv__(self, other)\nobject.__ifloordiv__(self, other)\nobject.__imod__(self, other)\nobject.__ipow__(self, other[, modulo])\nobject.__ilshift__(self, other)\nobject.__irshift__(self, other)\nobject.__iand__(self, other)\nobject.__ixor__(self, other)\nobject.__ior__(self, other)\n\n   These methods are called to implement the augmented arithmetic\n   assignments (``+=``, ``-=``, ``*=``, ``/=``, ``//=``, ``%=``,\n   ``**=``, ``<<=``, ``>>=``, ``&=``, ``^=``, ``|=``).  These methods\n   should attempt to do the operation in-place (modifying *self*) and\n   return the result (which could be, but does not have to be,\n   *self*).  If a specific method is not defined, the augmented\n   assignment falls back to the normal methods.  For instance, to\n   execute the statement ``x += y``, where *x* is an instance of a\n   class that has an ``__iadd__()`` method, ``x.__iadd__(y)`` is\n   called.  If *x* is an instance of a class that does not define a\n   ``__iadd__()`` method, ``x.__add__(y)`` and ``y.__radd__(x)`` are\n   considered, as with the evaluation of ``x + y``.\n\nobject.__neg__(self)\nobject.__pos__(self)\nobject.__abs__(self)\nobject.__invert__(self)\n\n   Called to implement the unary arithmetic operations (``-``, ``+``,\n   ``abs()`` and ``~``).\n\nobject.__complex__(self)\nobject.__int__(self)\nobject.__float__(self)\nobject.__round__(self[, n])\n\n   Called to implement the built-in functions ``complex()``,\n   ``int()``, ``float()`` and ``round()``.  Should return a value of\n   the appropriate type.\n\nobject.__index__(self)\n\n   Called to implement ``operator.index()``.  Also called whenever\n   Python needs an integer object (such as in slicing, or in the\n   built-in ``bin()``, ``hex()`` and ``oct()`` functions). Must return\n   an integer.\n\n\nWith Statement Context Managers\n===============================\n\nA *context manager* is an object that defines the runtime context to\nbe established when executing a ``with`` statement. The context\nmanager handles the entry into, and the exit from, the desired runtime\ncontext for the execution of the block of code.  Context managers are\nnormally invoked using the ``with`` statement (described in section\n*The with statement*), but can also be used by directly invoking their\nmethods.\n\nTypical uses of context managers include saving and restoring various\nkinds of global state, locking and unlocking resources, closing opened\nfiles, etc.\n\nFor more information on context managers, see *Context Manager Types*.\n\nobject.__enter__(self)\n\n   Enter the runtime context related to this object. The ``with``\n   statement will bind this method\'s return value to the target(s)\n   specified in the ``as`` clause of the statement, if any.\n\nobject.__exit__(self, exc_type, exc_value, traceback)\n\n   Exit the runtime context related to this object. The parameters\n   describe the exception that caused the context to be exited. If the\n   context was exited without an exception, all three arguments will\n   be ``None``.\n\n   If an exception is supplied, and the method wishes to suppress the\n   exception (i.e., prevent it from being propagated), it should\n   return a true value. Otherwise, the exception will be processed\n   normally upon exit from this method.\n\n   Note that ``__exit__()`` methods should not reraise the passed-in\n   exception; this is the caller\'s responsibility.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n\n\nSpecial method lookup\n=====================\n\nFor custom classes, implicit invocations of special methods are only\nguaranteed to work correctly if defined on an object\'s type, not in\nthe object\'s instance dictionary.  That behaviour is the reason why\nthe following code raises an exception:\n\n   >>> class C:\n   ...     pass\n   ...\n   >>> c = C()\n   >>> c.__len__ = lambda: 5\n   >>> len(c)\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   TypeError: object of type \'C\' has no len()\n\nThe rationale behind this behaviour lies with a number of special\nmethods such as ``__hash__()`` and ``__repr__()`` that are implemented\nby all objects, including type objects. If the implicit lookup of\nthese methods used the conventional lookup process, they would fail\nwhen invoked on the type object itself:\n\n   >>> 1 .__hash__() == hash(1)\n   True\n   >>> int.__hash__() == hash(int)\n   Traceback (most recent call last):\n     File "<stdin>", line 1, in <module>\n   TypeError: descriptor \'__hash__\' of \'int\' object needs an argument\n\nIncorrectly attempting to invoke an unbound method of a class in this\nway is sometimes referred to as \'metaclass confusion\', and is avoided\nby bypassing the instance when looking up special methods:\n\n   >>> type(1).__hash__(1) == hash(1)\n   True\n   >>> type(int).__hash__(int) == hash(int)\n   True\n\nIn addition to bypassing any instance attributes in the interest of\ncorrectness, implicit special method lookup generally also bypasses\nthe ``__getattribute__()`` method even of the object\'s metaclass:\n\n   >>> class Meta(type):\n   ...    def __getattribute__(*args):\n   ...       print("Metaclass getattribute invoked")\n   ...       return type.__getattribute__(*args)\n   ...\n   >>> class C(object, metaclass=Meta):\n   ...     def __len__(self):\n   ...         return 10\n   ...     def __getattribute__(*args):\n   ...         print("Class getattribute invoked")\n   ...         return object.__getattribute__(*args)\n   ...\n   >>> c = C()\n   >>> c.__len__()                 # Explicit lookup via instance\n   Class getattribute invoked\n   10\n   >>> type(c).__len__(c)          # Explicit lookup via type\n   Metaclass getattribute invoked\n   10\n   >>> len(c)                      # Implicit lookup\n   10\n\nBypassing the ``__getattribute__()`` machinery in this fashion\nprovides significant scope for speed optimisations within the\ninterpreter, at the cost of some flexibility in the handling of\nspecial methods (the special method *must* be set on the class object\nitself in order to be consistently invoked by the interpreter).\n\n-[ Footnotes ]-\n\n[1] It *is* possible in some cases to change an object\'s type, under\n    certain controlled conditions. It generally isn\'t a good idea\n    though, since it can lead to some very strange behaviour if it is\n    handled incorrectly.\n\n[2] For operands of the same type, it is assumed that if the non-\n    reflected method (such as ``__add__()``) fails the operation is\n    not supported, which is why the reflected method is not called.\n',
+ 'string-methods': '\nString Methods\n**************\n\nString objects support the methods listed below.\n\nIn addition, Python\'s strings support the sequence type methods\ndescribed in the *Sequence Types --- str, bytes, bytearray, list,\ntuple, range* section. To output formatted strings, see the *String\nFormatting* section. Also, see the ``re`` module for string functions\nbased on regular expressions.\n\nstr.capitalize()\n\n   Return a copy of the string with its first character capitalized\n   and the rest lowercased.\n\nstr.center(width[, fillchar])\n\n   Return centered in a string of length *width*. Padding is done\n   using the specified *fillchar* (default is a space).\n\nstr.count(sub[, start[, end]])\n\n   Return the number of non-overlapping occurrences of substring *sub*\n   in the range [*start*, *end*].  Optional arguments *start* and\n   *end* are interpreted as in slice notation.\n\nstr.encode(encoding="utf-8", errors="strict")\n\n   Return an encoded version of the string as a bytes object. Default\n   encoding is ``\'utf-8\'``. *errors* may be given to set a different\n   error handling scheme. The default for *errors* is ``\'strict\'``,\n   meaning that encoding errors raise a ``UnicodeError``. Other\n   possible values are ``\'ignore\'``, ``\'replace\'``,\n   ``\'xmlcharrefreplace\'``, ``\'backslashreplace\'`` and any other name\n   registered via ``codecs.register_error()``, see section *Codec Base\n   Classes*. For a list of possible encodings, see section *Standard\n   Encodings*.\n\n   Changed in version 3.1: Support for keyword arguments added.\n\nstr.endswith(suffix[, start[, end]])\n\n   Return ``True`` if the string ends with the specified *suffix*,\n   otherwise return ``False``.  *suffix* can also be a tuple of\n   suffixes to look for.  With optional *start*, test beginning at\n   that position.  With optional *end*, stop comparing at that\n   position.\n\nstr.expandtabs([tabsize])\n\n   Return a copy of the string where all tab characters are replaced\n   by one or more spaces, depending on the current column and the\n   given tab size.  The column number is reset to zero after each\n   newline occurring in the string. If *tabsize* is not given, a tab\n   size of ``8`` characters is assumed.  This doesn\'t understand other\n   non-printing characters or escape sequences.\n\nstr.find(sub[, start[, end]])\n\n   Return the lowest index in the string where substring *sub* is\n   found, such that *sub* is contained in the slice ``s[start:end]``.\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` if *sub* is not found.\n\nstr.format(*args, **kwargs)\n\n   Perform a string formatting operation.  The string on which this\n   method is called can contain literal text or replacement fields\n   delimited by braces ``{}``.  Each replacement field contains either\n   the numeric index of a positional argument, or the name of a\n   keyword argument.  Returns a copy of the string where each\n   replacement field is replaced with the string value of the\n   corresponding argument.\n\n   >>> "The sum of 1 + 2 is {0}".format(1+2)\n   \'The sum of 1 + 2 is 3\'\n\n   See *Format String Syntax* for a description of the various\n   formatting options that can be specified in format strings.\n\nstr.format_map(mapping)\n\n   Similar to ``str.format(**mapping)``, except that ``mapping`` is\n   used directly and not copied to a ``dict`` .  This is useful if for\n   example ``mapping`` is a dict subclass:\n\n   >>> class Default(dict):\n   ...     def __missing__(self, key):\n   ...         return key\n   ...\n   >>> \'{name} was born in {country}\'.format_map(Default(name=\'Guido\'))\n   \'Guido was born in country\'\n\n   New in version 3.2.\n\nstr.index(sub[, start[, end]])\n\n   Like ``find()``, but raise ``ValueError`` when the substring is not\n   found.\n\nstr.isalnum()\n\n   Return true if all characters in the string are alphanumeric and\n   there is at least one character, false otherwise.  A character\n   ``c`` is alphanumeric if one of the following returns ``True``:\n   ``c.isalpha()``, ``c.isdecimal()``, ``c.isdigit()``, or\n   ``c.isnumeric()``.\n\nstr.isalpha()\n\n   Return true if all characters in the string are alphabetic and\n   there is at least one character, false otherwise.  Alphabetic\n   characters are those characters defined in the Unicode character\n   database as "Letter", i.e., those with general category property\n   being one of "Lm", "Lt", "Lu", "Ll", or "Lo".  Note that this is\n   different from the "Alphabetic" property defined in the Unicode\n   Standard.\n\nstr.isdecimal()\n\n   Return true if all characters in the string are decimal characters\n   and there is at least one character, false otherwise. Decimal\n   characters are those from general category "Nd". This category\n   includes digit characters, and all characters that that can be used\n   to form decimal-radix numbers, e.g. U+0660, ARABIC-INDIC DIGIT\n   ZERO.\n\nstr.isdigit()\n\n   Return true if all characters in the string are digits and there is\n   at least one character, false otherwise.  Digits include decimal\n   characters and digits that need special handling, such as the\n   compatibility superscript digits.  Formally, a digit is a character\n   that has the property value Numeric_Type=Digit or\n   Numeric_Type=Decimal.\n\nstr.isidentifier()\n\n   Return true if the string is a valid identifier according to the\n   language definition, section *Identifiers and keywords*.\n\nstr.islower()\n\n   Return true if all cased characters in the string are lowercase and\n   there is at least one cased character, false otherwise.  Cased\n   characters are those with general category property being one of\n   "Lu", "Ll", or "Lt" and lowercase characters are those with general\n   category property "Ll".\n\nstr.isnumeric()\n\n   Return true if all characters in the string are numeric characters,\n   and there is at least one character, false otherwise. Numeric\n   characters include digit characters, and all characters that have\n   the Unicode numeric value property, e.g. U+2155, VULGAR FRACTION\n   ONE FIFTH.  Formally, numeric characters are those with the\n   property value Numeric_Type=Digit, Numeric_Type=Decimal or\n   Numeric_Type=Numeric.\n\nstr.isprintable()\n\n   Return true if all characters in the string are printable or the\n   string is empty, false otherwise.  Nonprintable characters are\n   those characters defined in the Unicode character database as\n   "Other" or "Separator", excepting the ASCII space (0x20) which is\n   considered printable.  (Note that printable characters in this\n   context are those which should not be escaped when ``repr()`` is\n   invoked on a string.  It has no bearing on the handling of strings\n   written to ``sys.stdout`` or ``sys.stderr``.)\n\nstr.isspace()\n\n   Return true if there are only whitespace characters in the string\n   and there is at least one character, false otherwise.  Whitespace\n   characters  are those characters defined in the Unicode character\n   database as "Other" or "Separator" and those with bidirectional\n   property being one of "WS", "B", or "S".\n\nstr.istitle()\n\n   Return true if the string is a titlecased string and there is at\n   least one character, for example uppercase characters may only\n   follow uncased characters and lowercase characters only cased ones.\n   Return false otherwise.\n\nstr.isupper()\n\n   Return true if all cased characters in the string are uppercase and\n   there is at least one cased character, false otherwise. Cased\n   characters are those with general category property being one of\n   "Lu", "Ll", or "Lt" and uppercase characters are those with general\n   category property "Lu".\n\nstr.join(iterable)\n\n   Return a string which is the concatenation of the strings in the\n   *iterable* *iterable*.  A ``TypeError`` will be raised if there are\n   any non-string values in *seq*, including ``bytes`` objects.  The\n   separator between elements is the string providing this method.\n\nstr.ljust(width[, fillchar])\n\n   Return the string left justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space).  The original string is returned if *width* is less than\n   ``len(s)``.\n\nstr.lower()\n\n   Return a copy of the string converted to lowercase.\n\nstr.lstrip([chars])\n\n   Return a copy of the string with leading characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a prefix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.lstrip()\n   \'spacious   \'\n   >>> \'www.example.com\'.lstrip(\'cmowz.\')\n   \'example.com\'\n\nstatic str.maketrans(x[, y[, z]])\n\n   This static method returns a translation table usable for\n   ``str.translate()``.\n\n   If there is only one argument, it must be a dictionary mapping\n   Unicode ordinals (integers) or characters (strings of length 1) to\n   Unicode ordinals, strings (of arbitrary lengths) or None.\n   Character keys will then be converted to ordinals.\n\n   If there are two arguments, they must be strings of equal length,\n   and in the resulting dictionary, each character in x will be mapped\n   to the character at the same position in y.  If there is a third\n   argument, it must be a string, whose characters will be mapped to\n   None in the result.\n\nstr.partition(sep)\n\n   Split the string at the first occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing the string itself, followed by\n   two empty strings.\n\nstr.replace(old, new[, count])\n\n   Return a copy of the string with all occurrences of substring *old*\n   replaced by *new*.  If the optional argument *count* is given, only\n   the first *count* occurrences are replaced.\n\nstr.rfind(sub[, start[, end]])\n\n   Return the highest index in the string where substring *sub* is\n   found, such that *sub* is contained within ``s[start:end]``.\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` on failure.\n\nstr.rindex(sub[, start[, end]])\n\n   Like ``rfind()`` but raises ``ValueError`` when the substring *sub*\n   is not found.\n\nstr.rjust(width[, fillchar])\n\n   Return the string right justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space). The original string is returned if *width* is less than\n   ``len(s)``.\n\nstr.rpartition(sep)\n\n   Split the string at the last occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing two empty strings, followed by\n   the string itself.\n\nstr.rsplit([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string. If *maxsplit* is given, at most *maxsplit* splits\n   are done, the *rightmost* ones.  If *sep* is not specified or\n   ``None``, any whitespace string is a separator.  Except for\n   splitting from the right, ``rsplit()`` behaves like ``split()``\n   which is described in detail below.\n\nstr.rstrip([chars])\n\n   Return a copy of the string with trailing characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a suffix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.rstrip()\n   \'   spacious\'\n   >>> \'mississippi\'.rstrip(\'ipz\')\n   \'mississ\'\n\nstr.split([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string.  If *maxsplit* is given, at most *maxsplit*\n   splits are done (thus, the list will have at most ``maxsplit+1``\n   elements).  If *maxsplit* is not specified, then there is no limit\n   on the number of splits (all possible splits are made).\n\n   If *sep* is given, consecutive delimiters are not grouped together\n   and are deemed to delimit empty strings (for example,\n   ``\'1,,2\'.split(\',\')`` returns ``[\'1\', \'\', \'2\']``).  The *sep*\n   argument may consist of multiple characters (for example,\n   ``\'1<>2<>3\'.split(\'<>\')`` returns ``[\'1\', \'2\', \'3\']``). Splitting\n   an empty string with a specified separator returns ``[\'\']``.\n\n   If *sep* is not specified or is ``None``, a different splitting\n   algorithm is applied: runs of consecutive whitespace are regarded\n   as a single separator, and the result will contain no empty strings\n   at the start or end if the string has leading or trailing\n   whitespace.  Consequently, splitting an empty string or a string\n   consisting of just whitespace with a ``None`` separator returns\n   ``[]``.\n\n   For example, ``\' 1  2   3  \'.split()`` returns ``[\'1\', \'2\', \'3\']``,\n   and ``\'  1  2   3  \'.split(None, 1)`` returns ``[\'1\', \'2   3  \']``.\n\nstr.splitlines([keepends])\n\n   Return a list of the lines in the string, breaking at line\n   boundaries.  Line breaks are not included in the resulting list\n   unless *keepends* is given and true.\n\nstr.startswith(prefix[, start[, end]])\n\n   Return ``True`` if string starts with the *prefix*, otherwise\n   return ``False``. *prefix* can also be a tuple of prefixes to look\n   for.  With optional *start*, test string beginning at that\n   position.  With optional *end*, stop comparing string at that\n   position.\n\nstr.strip([chars])\n\n   Return a copy of the string with the leading and trailing\n   characters removed. The *chars* argument is a string specifying the\n   set of characters to be removed. If omitted or ``None``, the\n   *chars* argument defaults to removing whitespace. The *chars*\n   argument is not a prefix or suffix; rather, all combinations of its\n   values are stripped:\n\n   >>> \'   spacious   \'.strip()\n   \'spacious\'\n   >>> \'www.example.com\'.strip(\'cmowz.\')\n   \'example\'\n\nstr.swapcase()\n\n   Return a copy of the string with uppercase characters converted to\n   lowercase and vice versa.\n\nstr.title()\n\n   Return a titlecased version of the string where words start with an\n   uppercase character and the remaining characters are lowercase.\n\n   The algorithm uses a simple language-independent definition of a\n   word as groups of consecutive letters.  The definition works in\n   many contexts but it means that apostrophes in contractions and\n   possessives form word boundaries, which may not be the desired\n   result:\n\n      >>> "they\'re bill\'s friends from the UK".title()\n      "They\'Re Bill\'S Friends From The Uk"\n\n   A workaround for apostrophes can be constructed using regular\n   expressions:\n\n      >>> import re\n      >>> def titlecase(s):\n              return re.sub(r"[A-Za-z]+(\'[A-Za-z]+)?",\n                            lambda mo: mo.group(0)[0].upper() +\n                                       mo.group(0)[1:].lower(),\n                            s)\n\n      >>> titlecase("they\'re bill\'s friends.")\n      "They\'re Bill\'s Friends."\n\nstr.translate(map)\n\n   Return a copy of the *s* where all characters have been mapped\n   through the *map* which must be a dictionary of Unicode ordinals\n   (integers) to Unicode ordinals, strings or ``None``.  Unmapped\n   characters are left untouched. Characters mapped to ``None`` are\n   deleted.\n\n   You can use ``str.maketrans()`` to create a translation map from\n   character-to-character mappings in different formats.\n\n   Note: An even more flexible approach is to create a custom character\n     mapping codec using the ``codecs`` module (see\n     ``encodings.cp1251`` for an example).\n\nstr.upper()\n\n   Return a copy of the string converted to uppercase.\n\nstr.zfill(width)\n\n   Return the numeric string left filled with zeros in a string of\n   length *width*.  A sign prefix is handled correctly.  The original\n   string is returned if *width* is less than ``len(s)``.\n',
+ 'strings': '\nString and Bytes literals\n*************************\n\nString literals are described by the following lexical definitions:\n\n   stringliteral   ::= [stringprefix](shortstring | longstring)\n   stringprefix    ::= "r" | "R"\n   shortstring     ::= "\'" shortstringitem* "\'" | \'"\' shortstringitem* \'"\'\n   longstring      ::= "\'\'\'" longstringitem* "\'\'\'" | \'"""\' longstringitem* \'"""\'\n   shortstringitem ::= shortstringchar | stringescapeseq\n   longstringitem  ::= longstringchar | stringescapeseq\n   shortstringchar ::= <any source character except "\\" or newline or the quote>\n   longstringchar  ::= <any source character except "\\">\n   stringescapeseq ::= "\\" <any source character>\n\n   bytesliteral   ::= bytesprefix(shortbytes | longbytes)\n   bytesprefix    ::= "b" | "B" | "br" | "Br" | "bR" | "BR"\n   shortbytes     ::= "\'" shortbytesitem* "\'" | \'"\' shortbytesitem* \'"\'\n   longbytes      ::= "\'\'\'" longbytesitem* "\'\'\'" | \'"""\' longbytesitem* \'"""\'\n   shortbytesitem ::= shortbyteschar | bytesescapeseq\n   longbytesitem  ::= longbyteschar | bytesescapeseq\n   shortbyteschar ::= <any ASCII character except "\\" or newline or the quote>\n   longbyteschar  ::= <any ASCII character except "\\">\n   bytesescapeseq ::= "\\" <any ASCII character>\n\nOne syntactic restriction not indicated by these productions is that\nwhitespace is not allowed between the ``stringprefix`` or\n``bytesprefix`` and the rest of the literal. The source character set\nis defined by the encoding declaration; it is UTF-8 if no encoding\ndeclaration is given in the source file; see section *Encoding\ndeclarations*.\n\nIn plain English: Both types of literals can be enclosed in matching\nsingle quotes (``\'``) or double quotes (``"``).  They can also be\nenclosed in matching groups of three single or double quotes (these\nare generally referred to as *triple-quoted strings*).  The backslash\n(``\\``) character is used to escape characters that otherwise have a\nspecial meaning, such as newline, backslash itself, or the quote\ncharacter.\n\nBytes literals are always prefixed with ``\'b\'`` or ``\'B\'``; they\nproduce an instance of the ``bytes`` type instead of the ``str`` type.\nThey may only contain ASCII characters; bytes with a numeric value of\n128 or greater must be expressed with escapes.\n\nBoth string and bytes literals may optionally be prefixed with a\nletter ``\'r\'`` or ``\'R\'``; such strings are called *raw strings* and\ntreat backslashes as literal characters.  As a result, in string\nliterals, ``\'\\U\'`` and ``\'\\u\'`` escapes in raw strings are not treated\nspecially.\n\nIn triple-quoted strings, unescaped newlines and quotes are allowed\n(and are retained), except that three unescaped quotes in a row\nterminate the string.  (A "quote" is the character used to open the\nstring, i.e. either ``\'`` or ``"``.)\n\nUnless an ``\'r\'`` or ``\'R\'`` prefix is present, escape sequences in\nstrings are interpreted according to rules similar to those used by\nStandard C.  The recognized escape sequences are:\n\n+-------------------+-----------------------------------+---------+\n| Escape Sequence   | Meaning                           | Notes   |\n+===================+===================================+=========+\n| ``\\newline``      | Backslash and newline ignored     |         |\n+-------------------+-----------------------------------+---------+\n| ``\\\\``            | Backslash (``\\``)                 |         |\n+-------------------+-----------------------------------+---------+\n| ``\\\'``            | Single quote (``\'``)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\"``            | Double quote (``"``)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\a``            | ASCII Bell (BEL)                  |         |\n+-------------------+-----------------------------------+---------+\n| ``\\b``            | ASCII Backspace (BS)              |         |\n+-------------------+-----------------------------------+---------+\n| ``\\f``            | ASCII Formfeed (FF)               |         |\n+-------------------+-----------------------------------+---------+\n| ``\\n``            | ASCII Linefeed (LF)               |         |\n+-------------------+-----------------------------------+---------+\n| ``\\r``            | ASCII Carriage Return (CR)        |         |\n+-------------------+-----------------------------------+---------+\n| ``\\t``            | ASCII Horizontal Tab (TAB)        |         |\n+-------------------+-----------------------------------+---------+\n| ``\\v``            | ASCII Vertical Tab (VT)           |         |\n+-------------------+-----------------------------------+---------+\n| ``\\ooo``          | Character with octal value *ooo*  | (1,3)   |\n+-------------------+-----------------------------------+---------+\n| ``\\xhh``          | Character with hex value *hh*     | (2,3)   |\n+-------------------+-----------------------------------+---------+\n\nEscape sequences only recognized in string literals are:\n\n+-------------------+-----------------------------------+---------+\n| Escape Sequence   | Meaning                           | Notes   |\n+===================+===================================+=========+\n| ``\\N{name}``      | Character named *name* in the     |         |\n|                   | Unicode database                  |         |\n+-------------------+-----------------------------------+---------+\n| ``\\uxxxx``        | Character with 16-bit hex value   | (4)     |\n|                   | *xxxx*                            |         |\n+-------------------+-----------------------------------+---------+\n| ``\\Uxxxxxxxx``    | Character with 32-bit hex value   | (5)     |\n|                   | *xxxxxxxx*                        |         |\n+-------------------+-----------------------------------+---------+\n\nNotes:\n\n1. As in Standard C, up to three octal digits are accepted.\n\n2. Unlike in Standard C, exactly two hex digits are required.\n\n3. In a bytes literal, hexadecimal and octal escapes denote the byte\n   with the given value. In a string literal, these escapes denote a\n   Unicode character with the given value.\n\n4. Individual code units which form parts of a surrogate pair can be\n   encoded using this escape sequence.  Exactly four hex digits are\n   required.\n\n5. Any Unicode character can be encoded this way, but characters\n   outside the Basic Multilingual Plane (BMP) will be encoded using a\n   surrogate pair if Python is compiled to use 16-bit code units (the\n   default).  Exactly eight hex digits are required.\n\nUnlike Standard C, all unrecognized escape sequences are left in the\nstring unchanged, i.e., *the backslash is left in the string*.  (This\nbehavior is useful when debugging: if an escape sequence is mistyped,\nthe resulting output is more easily recognized as broken.)  It is also\nimportant to note that the escape sequences only recognized in string\nliterals fall into the category of unrecognized escapes for bytes\nliterals.\n\nEven in a raw string, string quotes can be escaped with a backslash,\nbut the backslash remains in the string; for example, ``r"\\""`` is a\nvalid string literal consisting of two characters: a backslash and a\ndouble quote; ``r"\\"`` is not a valid string literal (even a raw\nstring cannot end in an odd number of backslashes).  Specifically, *a\nraw string cannot end in a single backslash* (since the backslash\nwould escape the following quote character).  Note also that a single\nbackslash followed by a newline is interpreted as those two characters\nas part of the string, *not* as a line continuation.\n',
+ 'subscriptions': '\nSubscriptions\n*************\n\nA subscription selects an item of a sequence (string, tuple or list)\nor mapping (dictionary) object:\n\n   subscription ::= primary "[" expression_list "]"\n\nThe primary must evaluate to an object that supports subscription,\ne.g. a list or dictionary.  User-defined objects can support\nsubscription by defining a ``__getitem__()`` method.\n\nFor built-in objects, there are two types of objects that support\nsubscription:\n\nIf the primary is a mapping, the expression list must evaluate to an\nobject whose value is one of the keys of the mapping, and the\nsubscription selects the value in the mapping that corresponds to that\nkey.  (The expression list is a tuple except if it has exactly one\nitem.)\n\nIf the primary is a sequence, the expression (list) must evaluate to\nan integer or a slice (as discussed in the following section).\n\nThe formal syntax makes no special provision for negative indices in\nsequences; however, built-in sequences all provide a ``__getitem__()``\nmethod that interprets negative indices by adding the length of the\nsequence to the index (so that ``x[-1]`` selects the last item of\n``x``).  The resulting value must be a nonnegative integer less than\nthe number of items in the sequence, and the subscription selects the\nitem whose index is that value (counting from zero). Since the support\nfor negative indices and slicing occurs in the object\'s\n``__getitem__()`` method, subclasses overriding this method will need\nto explicitly add that support.\n\nA string\'s items are characters.  A character is not a separate data\ntype but a string of exactly one character.\n',
  'truth': "\nTruth Value Testing\n*******************\n\nAny object can be tested for truth value, for use in an ``if`` or\n``while`` condition or as operand of the Boolean operations below. The\nfollowing values are considered false:\n\n* ``None``\n\n* ``False``\n\n* zero of any numeric type, for example, ``0``, ``0.0``, ``0j``.\n\n* any empty sequence, for example, ``''``, ``()``, ``[]``.\n\n* any empty mapping, for example, ``{}``.\n\n* instances of user-defined classes, if the class defines a\n  ``__bool__()`` or ``__len__()`` method, when that method returns the\n  integer zero or ``bool`` value ``False``. [1]\n\nAll other values are considered true --- so objects of many types are\nalways true.\n\nOperations and built-in functions that have a Boolean result always\nreturn ``0`` or ``False`` for false and ``1`` or ``True`` for true,\nunless otherwise stated. (Important exception: the Boolean operations\n``or`` and ``and`` always return one of their operands.)\n",
- 'try': '\nThe ``try`` statement\n*********************\n\nThe ``try`` statement specifies exception handlers and/or cleanup code\nfor a group of statements:\n\n   try_stmt  ::= try1_stmt | try2_stmt\n   try1_stmt ::= "try" ":" suite\n                 ("except" [expression ["as" target]] ":" suite)+\n                 ["else" ":" suite]\n                 ["finally" ":" suite]\n   try2_stmt ::= "try" ":" suite\n                 "finally" ":" suite\n\nThe ``except`` clause(s) specify one or more exception handlers. When\nno exception occurs in the ``try`` clause, no exception handler is\nexecuted. When an exception occurs in the ``try`` suite, a search for\nan exception handler is started.  This search inspects the except\nclauses in turn until one is found that matches the exception.  An\nexpression-less except clause, if present, must be last; it matches\nany exception.  For an except clause with an expression, that\nexpression is evaluated, and the clause matches the exception if the\nresulting object is "compatible" with the exception.  An object is\ncompatible with an exception if it is the class or a base class of the\nexception object or a tuple containing an item compatible with the\nexception.\n\nIf no except clause matches the exception, the search for an exception\nhandler continues in the surrounding code and on the invocation stack.\n[1]\n\nIf the evaluation of an expression in the header of an except clause\nraises an exception, the original search for a handler is canceled and\na search starts for the new exception in the surrounding code and on\nthe call stack (it is treated as if the entire ``try`` statement\nraised the exception).\n\nWhen a matching except clause is found, the exception is assigned to\nthe target specified after the ``as`` keyword in that except clause,\nif present, and the except clause\'s suite is executed.  All except\nclauses must have an executable block.  When the end of this block is\nreached, execution continues normally after the entire try statement.\n(This means that if two nested handlers exist for the same exception,\nand the exception occurs in the try clause of the inner handler, the\nouter handler will not handle the exception.)\n\nWhen an exception has been assigned using ``as target``, it is cleared\nat the end of the except clause.  This is as if\n\n   except E as N:\n       foo\n\nwas translated to\n\n   except E as N:\n       try:\n           foo\n       finally:\n           N = None\n           del N\n\nThat means that you have to assign the exception to a different name\nif you want to be able to refer to it after the except clause.  The\nreason for this is that with the traceback attached to them,\nexceptions will form a reference cycle with the stack frame, keeping\nall locals in that frame alive until the next garbage collection\noccurs.\n\nBefore an except clause\'s suite is executed, details about the\nexception are stored in the ``sys`` module and can be access via\n``sys.exc_info()``. ``sys.exc_info()`` returns a 3-tuple consisting\nof: ``exc_type``, the exception class; ``exc_value``, the exception\ninstance; ``exc_traceback``, a traceback object (see section *The\nstandard type hierarchy*) identifying the point in the program where\nthe exception occurred. ``sys.exc_info()`` values are restored to\ntheir previous values (before the call) when returning from a function\nthat handled an exception.\n\nThe optional ``else`` clause is executed if and when control flows off\nthe end of the ``try`` clause. [2] Exceptions in the ``else`` clause\nare not handled by the preceding ``except`` clauses.\n\nIf ``finally`` is present, it specifies a \'cleanup\' handler.  The\n``try`` clause is executed, including any ``except`` and ``else``\nclauses.  If an exception occurs in any of the clauses and is not\nhandled, the exception is temporarily saved. The ``finally`` clause is\nexecuted.  If there is a saved exception, it is re-raised at the end\nof the ``finally`` clause. If the ``finally`` clause raises another\nexception or executes a ``return`` or ``break`` statement, the saved\nexception is lost.  The exception information is not available to the\nprogram during execution of the ``finally`` clause.\n\nWhen a ``return``, ``break`` or ``continue`` statement is executed in\nthe ``try`` suite of a ``try``...``finally`` statement, the\n``finally`` clause is also executed \'on the way out.\' A ``continue``\nstatement is illegal in the ``finally`` clause. (The reason is a\nproblem with the current implementation --- this restriction may be\nlifted in the future).\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information on using the ``raise`` statement to\ngenerate exceptions may be found in section *The raise statement*.\n',
- 'types': '\nThe standard type hierarchy\n***************************\n\nBelow is a list of the types that are built into Python.  Extension\nmodules (written in C, Java, or other languages, depending on the\nimplementation) can define additional types.  Future versions of\nPython may add types to the type hierarchy (e.g., rational numbers,\nefficiently stored arrays of integers, etc.), although such additions\nwill often be provided via the standard library instead.\n\nSome of the type descriptions below contain a paragraph listing\n\'special attributes.\'  These are attributes that provide access to the\nimplementation and are not intended for general use.  Their definition\nmay change in the future.\n\nNone\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name ``None``.\n   It is used to signify the absence of a value in many situations,\n   e.g., it is returned from functions that don\'t explicitly return\n   anything. Its truth value is false.\n\nNotImplemented\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name\n   ``NotImplemented``. Numeric methods and rich comparison methods may\n   return this value if they do not implement the operation for the\n   operands provided.  (The interpreter will then try the reflected\n   operation, or some other fallback, depending on the operator.)  Its\n   truth value is true.\n\nEllipsis\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the literal ``...`` or the\n   built-in name ``Ellipsis``.  Its truth value is true.\n\n``numbers.Number``\n   These are created by numeric literals and returned as results by\n   arithmetic operators and arithmetic built-in functions.  Numeric\n   objects are immutable; once created their value never changes.\n   Python numbers are of course strongly related to mathematical\n   numbers, but subject to the limitations of numerical representation\n   in computers.\n\n   Python distinguishes between integers, floating point numbers, and\n   complex numbers:\n\n   ``numbers.Integral``\n      These represent elements from the mathematical set of integers\n      (positive and negative).\n\n      There are two types of integers:\n\n      Integers (``int``)\n\n         These represent numbers in an unlimited range, subject to\n         available (virtual) memory only.  For the purpose of shift\n         and mask operations, a binary representation is assumed, and\n         negative numbers are represented in a variant of 2\'s\n         complement which gives the illusion of an infinite string of\n         sign bits extending to the left.\n\n      Booleans (``bool``)\n         These represent the truth values False and True.  The two\n         objects representing the values False and True are the only\n         Boolean objects. The Boolean type is a subtype of the integer\n         type, and Boolean values behave like the values 0 and 1,\n         respectively, in almost all contexts, the exception being\n         that when converted to a string, the strings ``"False"`` or\n         ``"True"`` are returned, respectively.\n\n      The rules for integer representation are intended to give the\n      most meaningful interpretation of shift and mask operations\n      involving negative integers.\n\n   ``numbers.Real`` (``float``)\n      These represent machine-level double precision floating point\n      numbers. You are at the mercy of the underlying machine\n      architecture (and C or Java implementation) for the accepted\n      range and handling of overflow. Python does not support single-\n      precision floating point numbers; the savings in processor and\n      memory usage that are usually the reason for using these is\n      dwarfed by the overhead of using objects in Python, so there is\n      no reason to complicate the language with two kinds of floating\n      point numbers.\n\n   ``numbers.Complex`` (``complex``)\n      These represent complex numbers as a pair of machine-level\n      double precision floating point numbers.  The same caveats apply\n      as for floating point numbers. The real and imaginary parts of a\n      complex number ``z`` can be retrieved through the read-only\n      attributes ``z.real`` and ``z.imag``.\n\nSequences\n   These represent finite ordered sets indexed by non-negative\n   numbers. The built-in function ``len()`` returns the number of\n   items of a sequence. When the length of a sequence is *n*, the\n   index set contains the numbers 0, 1, ..., *n*-1.  Item *i* of\n   sequence *a* is selected by ``a[i]``.\n\n   Sequences also support slicing: ``a[i:j]`` selects all items with\n   index *k* such that *i* ``<=`` *k* ``<`` *j*.  When used as an\n   expression, a slice is a sequence of the same type.  This implies\n   that the index set is renumbered so that it starts at 0.\n\n   Some sequences also support "extended slicing" with a third "step"\n   parameter: ``a[i:j:k]`` selects all items of *a* with index *x*\n   where ``x = i + n*k``, *n* ``>=`` ``0`` and *i* ``<=`` *x* ``<``\n   *j*.\n\n   Sequences are distinguished according to their mutability:\n\n   Immutable sequences\n      An object of an immutable sequence type cannot change once it is\n      created.  (If the object contains references to other objects,\n      these other objects may be mutable and may be changed; however,\n      the collection of objects directly referenced by an immutable\n      object cannot change.)\n\n      The following types are immutable sequences:\n\n      Strings\n         The items of a string object are Unicode code units.  A\n         Unicode code unit is represented by a string object of one\n         item and can hold either a 16-bit or 32-bit value\n         representing a Unicode ordinal (the maximum value for the\n         ordinal is given in ``sys.maxunicode``, and depends on how\n         Python is configured at compile time).  Surrogate pairs may\n         be present in the Unicode object, and will be reported as two\n         separate items.  The built-in functions ``chr()`` and\n         ``ord()`` convert between code units and nonnegative integers\n         representing the Unicode ordinals as defined in the Unicode\n         Standard 3.0. Conversion from and to other encodings are\n         possible through the string method ``encode()``.\n\n      Tuples\n         The items of a tuple are arbitrary Python objects. Tuples of\n         two or more items are formed by comma-separated lists of\n         expressions.  A tuple of one item (a \'singleton\') can be\n         formed by affixing a comma to an expression (an expression by\n         itself does not create a tuple, since parentheses must be\n         usable for grouping of expressions).  An empty tuple can be\n         formed by an empty pair of parentheses.\n\n      Bytes\n         A bytes object is an immutable array.  The items are 8-bit\n         bytes, represented by integers in the range 0 <= x < 256.\n         Bytes literals (like ``b\'abc\'`` and the built-in function\n         ``bytes()`` can be used to construct bytes objects.  Also,\n         bytes objects can be decoded to strings via the ``decode()``\n         method.\n\n   Mutable sequences\n      Mutable sequences can be changed after they are created.  The\n      subscription and slicing notations can be used as the target of\n      assignment and ``del`` (delete) statements.\n\n      There are currently two intrinsic mutable sequence types:\n\n      Lists\n         The items of a list are arbitrary Python objects.  Lists are\n         formed by placing a comma-separated list of expressions in\n         square brackets. (Note that there are no special cases needed\n         to form lists of length 0 or 1.)\n\n      Byte Arrays\n         A bytearray object is a mutable array. They are created by\n         the built-in ``bytearray()`` constructor.  Aside from being\n         mutable (and hence unhashable), byte arrays otherwise provide\n         the same interface and functionality as immutable bytes\n         objects.\n\n      The extension module ``array`` provides an additional example of\n      a mutable sequence type, as does the ``collections`` module.\n\nSet types\n   These represent unordered, finite sets of unique, immutable\n   objects. As such, they cannot be indexed by any subscript. However,\n   they can be iterated over, and the built-in function ``len()``\n   returns the number of items in a set. Common uses for sets are fast\n   membership testing, removing duplicates from a sequence, and\n   computing mathematical operations such as intersection, union,\n   difference, and symmetric difference.\n\n   For set elements, the same immutability rules apply as for\n   dictionary keys. Note that numeric types obey the normal rules for\n   numeric comparison: if two numbers compare equal (e.g., ``1`` and\n   ``1.0``), only one of them can be contained in a set.\n\n   There are currently two intrinsic set types:\n\n   Sets\n      These represent a mutable set. They are created by the built-in\n      ``set()`` constructor and can be modified afterwards by several\n      methods, such as ``add()``.\n\n   Frozen sets\n      These represent an immutable set.  They are created by the\n      built-in ``frozenset()`` constructor.  As a frozenset is\n      immutable and *hashable*, it can be used again as an element of\n      another set, or as a dictionary key.\n\nMappings\n   These represent finite sets of objects indexed by arbitrary index\n   sets. The subscript notation ``a[k]`` selects the item indexed by\n   ``k`` from the mapping ``a``; this can be used in expressions and\n   as the target of assignments or ``del`` statements. The built-in\n   function ``len()`` returns the number of items in a mapping.\n\n   There is currently a single intrinsic mapping type:\n\n   Dictionaries\n      These represent finite sets of objects indexed by nearly\n      arbitrary values.  The only types of values not acceptable as\n      keys are values containing lists or dictionaries or other\n      mutable types that are compared by value rather than by object\n      identity, the reason being that the efficient implementation of\n      dictionaries requires a key\'s hash value to remain constant.\n      Numeric types used for keys obey the normal rules for numeric\n      comparison: if two numbers compare equal (e.g., ``1`` and\n      ``1.0``) then they can be used interchangeably to index the same\n      dictionary entry.\n\n      Dictionaries are mutable; they can be created by the ``{...}``\n      notation (see section *Dictionary displays*).\n\n      The extension modules ``dbm.ndbm`` and ``dbm.gnu`` provide\n      additional examples of mapping types, as does the\n      ``collections`` module.\n\nCallable types\n   These are the types to which the function call operation (see\n   section *Calls*) can be applied:\n\n   User-defined functions\n      A user-defined function object is created by a function\n      definition (see section *Function definitions*).  It should be\n      called with an argument list containing the same number of items\n      as the function\'s formal parameter list.\n\n      Special attributes:\n\n      +---------------------------+---------------------------------+-------------+\n      | Attribute                 | Meaning                         |             |\n      +===========================+=================================+=============+\n      | ``__doc__``               | The function\'s documentation    | Writable    |\n      |                           | string, or ``None`` if          |             |\n      |                           | unavailable                     |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__name__``              | The function\'s name             | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | ``__module__``            | The name of the module the      | Writable    |\n      |                           | function was defined in, or     |             |\n      |                           | ``None`` if unavailable.        |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__defaults__``          | A tuple containing default      | Writable    |\n      |                           | argument values for those       |             |\n      |                           | arguments that have defaults,   |             |\n      |                           | or ``None`` if no arguments     |             |\n      |                           | have a default value            |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__code__``              | The code object representing    | Writable    |\n      |                           | the compiled function body.     |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__globals__``           | A reference to the dictionary   | Read-only   |\n      |                           | that holds the function\'s       |             |\n      |                           | global variables --- the global |             |\n      |                           | namespace of the module in      |             |\n      |                           | which the function was defined. |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__dict__``              | The namespace supporting        | Writable    |\n      |                           | arbitrary function attributes.  |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__closure__``           | ``None`` or a tuple of cells    | Read-only   |\n      |                           | that contain bindings for the   |             |\n      |                           | function\'s free variables.      |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__annotations__``       | A dict containing annotations   | Writable    |\n      |                           | of parameters.

Regular attribute dot-notation is used to get and\n      set such attributes. *Note that the current implementation only\n      supports function attributes on user-defined functions. Function\n      attributes on built-in functions may be supported in the\n      future.*\n\n      Additional information about a function\'s definition can be\n      retrieved from its code object; see the description of internal\n      types below.\n\n   Instance methods\n      An instance method object combines a class, a class instance and\n      any callable object (normally a user-defined function).\n\n      Special read-only attributes: ``__self__`` is the class instance\n      object, ``__func__`` is the function object; ``__doc__`` is the\n      method\'s documentation (same as ``__func__.__doc__``);\n      ``__name__`` is the method name (same as ``__func__.__name__``);\n      ``__module__`` is the name of the module the method was defined\n      in, or ``None`` if unavailable.\n\n      Methods also support accessing (but not setting) the arbitrary\n      function attributes on the underlying function object.\n\n      User-defined method objects may be created when getting an\n      attribute of a class (perhaps via an instance of that class), if\n      that attribute is a user-defined function object or a class\n      method object.\n\n      When an instance method object is created by retrieving a user-\n      defined function object from a class via one of its instances,\n      its ``__self__`` attribute is the instance, and the method\n      object is said to be bound.  The new method\'s ``__func__``\n      attribute is the original function object.\n\n      When a user-defined method object is created by retrieving\n      another method object from a class or instance, the behaviour is\n      the same as for a function object, except that the ``__func__``\n      attribute of the new instance is not the original method object\n      but its ``__func__`` attribute.\n\n      When an instance method object is created by retrieving a class\n      method object from a class or instance, its ``__self__``\n      attribute is the class itself, and its ``__func__`` attribute is\n      the function object underlying the class method.\n\n      When an instance method object is called, the underlying\n      function (``__func__``) is called, inserting the class instance\n      (``__self__``) in front of the argument list.  For instance,\n      when ``C`` is a class which contains a definition for a function\n      ``f()``, and ``x`` is an instance of ``C``, calling ``x.f(1)``\n      is equivalent to calling ``C.f(x, 1)``.\n\n      When an instance method object is derived from a class method\n      object, the "class instance" stored in ``__self__`` will\n      actually be the class itself, so that calling either ``x.f(1)``\n      or ``C.f(1)`` is equivalent to calling ``f(C,1)`` where ``f`` is\n      the underlying function.\n\n      Note that the transformation from function object to instance\n      method object happens each time the attribute is retrieved from\n      the instance.  In some cases, a fruitful optimization is to\n      assign the attribute to a local variable and call that local\n      variable. Also notice that this transformation only happens for\n      user-defined functions; other callable objects (and all non-\n      callable objects) are retrieved without transformation.  It is\n      also important to note that user-defined functions which are\n      attributes of a class instance are not converted to bound\n      methods; this *only* happens when the function is an attribute\n      of the class.\n\n   Generator functions\n      A function or method which uses the ``yield`` statement (see\n      section *The yield statement*) is called a *generator function*.\n      Such a function, when called, always returns an iterator object\n      which can be used to execute the body of the function:  calling\n      the iterator\'s ``__next__()`` method will cause the function to\n      execute until it provides a value using the ``yield`` statement.\n      When the function executes a ``return`` statement or falls off\n      the end, a ``StopIteration`` exception is raised and the\n      iterator will have reached the end of the set of values to be\n      returned.\n\n   Built-in functions\n      A built-in function object is a wrapper around a C function.\n      Examples of built-in functions are ``len()`` and ``math.sin()``\n      (``math`` is a standard built-in module). The number and type of\n      the arguments are determined by the C function. Special read-\n      only attributes: ``__doc__`` is the function\'s documentation\n      string, or ``None`` if unavailable; ``__name__`` is the\n      function\'s name; ``__self__`` is set to ``None`` (but see the\n      next item); ``__module__`` is the name of the module the\n      function was defined in or ``None`` if unavailable.\n\n   Built-in methods\n      This is really a different disguise of a built-in function, this\n      time containing an object passed to the C function as an\n      implicit extra argument.  An example of a built-in method is\n      ``alist.append()``, assuming *alist* is a list object. In this\n      case, the special read-only attribute ``__self__`` is set to the\n      object denoted by *list*.\n\n   Classes\n      Classes are callable.  These objects normally act as factories\n      for new instances of themselves, but variations are possible for\n      class types that override ``__new__()``.  The arguments of the\n      call are passed to ``__new__()`` and, in the typical case, to\n      ``__init__()`` to initialize the new instance.\n\n   Class Instances\n      Instances of arbitrary classes can be made callable by defining\n      a ``__call__()`` method in their class.\n\nModules\n   Modules are imported by the ``import`` statement (see section *The\n   import statement*). A module object has a namespace implemented by\n   a dictionary object (this is the dictionary referenced by the\n   __globals__ attribute of functions defined in the module).\n   Attribute references are translated to lookups in this dictionary,\n   e.g., ``m.x`` is equivalent to ``m.__dict__["x"]``. A module object\n   does not contain the code object used to initialize the module\n   (since it isn\'t needed once the initialization is done).\n\n   Attribute assignment updates the module\'s namespace dictionary,\n   e.g., ``m.x = 1`` is equivalent to ``m.__dict__["x"] = 1``.\n\n   Special read-only attribute: ``__dict__`` is the module\'s namespace\n   as a dictionary object.\n\n   Predefined (writable) attributes: ``__name__`` is the module\'s\n   name; ``__doc__`` is the module\'s documentation string, or ``None``\n   if unavailable; ``__file__`` is the pathname of the file from which\n   the module was loaded, if it was loaded from a file. The\n   ``__file__`` attribute is not present for C modules that are\n   statically linked into the interpreter; for extension modules\n   loaded dynamically from a shared library, it is the pathname of the\n   shared library file.\n\nCustom classes\n   Custon class types are typically created by class definitions (see\n   section *Class definitions*).  A class has a namespace implemented\n   by a dictionary object. Class attribute references are translated\n   to lookups in this dictionary, e.g., ``C.x`` is translated to\n   ``C.__dict__["x"]`` (although there are a number of hooks which\n   allow for other means of locating attributes). When the attribute\n   name is not found there, the attribute search continues in the base\n   classes. This search of the base classes uses the C3 method\n   resolution order which behaves correctly even in the presence of\n   \'diamond\' inheritance structures where there are multiple\n   inheritance paths leading back to a common ancestor. Additional\n   details on the C3 MRO used by Python can be found in the\n   documentation accompanying the 2.3 release at\n   http://www.python.org/download/releases/2.3/mro/.\n\n   When a class attribute reference (for class ``C``, say) would yield\n   a class method object, it is transformed into an instance method\n   object whose ``__self__`` attributes is ``C``.  When it would yield\n   a static method object, it is transformed into the object wrapped\n   by the static method object. See section *Implementing Descriptors*\n   for another way in which attributes retrieved from a class may\n   differ from those actually contained in its ``__dict__``.\n\n   Class attribute assignments update the class\'s dictionary, never\n   the dictionary of a base class.\n\n   A class object can be called (see above) to yield a class instance\n   (see below).\n\n   Special attributes: ``__name__`` is the class name; ``__module__``\n   is the module name in which the class was defined; ``__dict__`` is\n   the dictionary containing the class\'s namespace; ``__bases__`` is a\n   tuple (possibly empty or a singleton) containing the base classes,\n   in the order of their occurrence in the base class list;\n   ``__doc__`` is the class\'s documentation string, or None if\n   undefined.\n\nClass instances\n   A class instance is created by calling a class object (see above).\n   A class instance has a namespace implemented as a dictionary which\n   is the first place in which attribute references are searched.\n   When an attribute is not found there, and the instance\'s class has\n   an attribute by that name, the search continues with the class\n   attributes.  If a class attribute is found that is a user-defined\n   function object, it is transformed into an instance method object\n   whose ``__self__`` attribute is the instance.  Static method and\n   class method objects are also transformed; see above under\n   "Classes".  See section *Implementing Descriptors* for another way\n   in which attributes of a class retrieved via its instances may\n   differ from the objects actually stored in the class\'s\n   ``__dict__``.  If no class attribute is found, and the object\'s\n   class has a ``__getattr__()`` method, that is called to satisfy the\n   lookup.\n\n   Attribute assignments and deletions update the instance\'s\n   dictionary, never a class\'s dictionary.  If the class has a\n   ``__setattr__()`` or ``__delattr__()`` method, this is called\n   instead of updating the instance dictionary directly.\n\n   Class instances can pretend to be numbers, sequences, or mappings\n   if they have methods with certain special names.  See section\n   *Special method names*.\n\n   Special attributes: ``__dict__`` is the attribute dictionary;\n   ``__class__`` is the instance\'s class.\n\nFiles\n   A file object represents an open file.  File objects are created by\n   the ``open()`` built-in function, and also by ``os.popen()``,\n   ``os.fdopen()``, and the ``makefile()`` method of socket objects\n   (and perhaps by other functions or methods provided by extension\n   modules).  The objects ``sys.stdin``, ``sys.stdout`` and\n   ``sys.stderr`` are initialized to file objects corresponding to the\n   interpreter\'s standard input, output and error streams.  See *File\n   Objects* for complete documentation of file objects.\n\nInternal types\n   A few types used internally by the interpreter are exposed to the\n   user. Their definitions may change with future versions of the\n   interpreter, but they are mentioned here for completeness.\n\n   Code objects\n      Code objects represent *byte-compiled* executable Python code,\n      or *bytecode*. The difference between a code object and a\n      function object is that the function object contains an explicit\n      reference to the function\'s globals (the module in which it was\n      defined), while a code object contains no context; also the\n      default argument values are stored in the function object, not\n      in the code object (because they represent values calculated at\n      run-time).  Unlike function objects, code objects are immutable\n      and contain no references (directly or indirectly) to mutable\n      objects.\n\n      Special read-only attributes: ``co_name`` gives the function\n      name; ``co_argcount`` is the number of positional arguments\n      (including arguments with default values); ``co_nlocals`` is the\n      number of local variables used by the function (including\n      arguments); ``co_varnames`` is a tuple containing the names of\n      the local variables (starting with the argument names);\n      ``co_cellvars`` is a tuple containing the names of local\n      variables that are referenced by nested functions;\n      ``co_freevars`` is a tuple containing the names of free\n      variables; ``co_code`` is a string representing the sequence of\n      bytecode instructions; ``co_consts`` is a tuple containing the\n      literals used by the bytecode; ``co_names`` is a tuple\n      containing the names used by the bytecode; ``co_filename`` is\n      the filename from which the code was compiled;\n      ``co_firstlineno`` is the first line number of the function;\n      ``co_lnotab`` is a string encoding the mapping from bytecode\n      offsets to line numbers (for details see the source code of the\n      interpreter); ``co_stacksize`` is the required stack size\n      (including local variables); ``co_flags`` is an integer encoding\n      a number of flags for the interpreter.\n\n      The following flag bits are defined for ``co_flags``: bit\n      ``0x04`` is set if the function uses the ``*arguments`` syntax\n      to accept an arbitrary number of positional arguments; bit\n      ``0x08`` is set if the function uses the ``**keywords`` syntax\n      to accept arbitrary keyword arguments; bit ``0x20`` is set if\n      the function is a generator.\n\n      Future feature declarations (``from __future__ import\n      division``) also use bits in ``co_flags`` to indicate whether a\n      code object was compiled with a particular feature enabled: bit\n      ``0x2000`` is set if the function was compiled with future\n      division enabled; bits ``0x10`` and ``0x1000`` were used in\n      earlier versions of Python.\n\n      Other bits in ``co_flags`` are reserved for internal use.\n\n      If a code object represents a function, the first item in\n      ``co_consts`` is the documentation string of the function, or\n      ``None`` if undefined.\n\n   Frame objects\n      Frame objects represent execution frames.  They may occur in\n      traceback objects (see below).\n\n      Special read-only attributes: ``f_back`` is to the previous\n      stack frame (towards the caller), or ``None`` if this is the\n      bottom stack frame; ``f_code`` is the code object being executed\n      in this frame; ``f_locals`` is the dictionary used to look up\n      local variables; ``f_globals`` is used for global variables;\n      ``f_builtins`` is used for built-in (intrinsic) names;\n      ``f_lasti`` gives the precise instruction (this is an index into\n      the bytecode string of the code object).\n\n      Special writable attributes: ``f_trace``, if not ``None``, is a\n      function called at the start of each source code line (this is\n      used by the debugger); ``f_lineno`` is the current line number\n      of the frame --- writing to this from within a trace function\n      jumps to the given line (only for the bottom-most frame).  A\n      debugger can implement a Jump command (aka Set Next Statement)\n      by writing to f_lineno.\n\n   Traceback objects\n      Traceback objects represent a stack trace of an exception.  A\n      traceback object is created when an exception occurs.  When the\n      search for an exception handler unwinds the execution stack, at\n      each unwound level a traceback object is inserted in front of\n      the current traceback.  When an exception handler is entered,\n      the stack trace is made available to the program. (See section\n      *The try statement*.) It is accessible as the third item of the\n      tuple returned by ``sys.exc_info()``. When the program contains\n      no suitable handler, the stack trace is written (nicely\n      formatted) to the standard error stream; if the interpreter is\n      interactive, it is also made available to the user as\n      ``sys.last_traceback``.\n\n      Special read-only attributes: ``tb_next`` is the next level in\n      the stack trace (towards the frame where the exception\n      occurred), or ``None`` if there is no next level; ``tb_frame``\n      points to the execution frame of the current level;\n      ``tb_lineno`` gives the line number where the exception\n      occurred; ``tb_lasti`` indicates the precise instruction.  The\n      line number and last instruction in the traceback may differ\n      from the line number of its frame object if the exception\n      occurred in a ``try`` statement with no matching except clause\n      or with a finally clause.\n\n   Slice objects\n      Slice objects are used to represent slices for ``__getitem__()``\n      methods.  They are also created by the built-in ``slice()``\n      function.\n\n      Special read-only attributes: ``start`` is the lower bound;\n      ``stop`` is the upper bound; ``step`` is the step value; each is\n      ``None`` if omitted. These attributes can have any type.\n\n      Slice objects support one method:\n\n      slice.indices(self, length)\n\n         This method takes a single integer argument *length* and\n         computes information about the slice that the slice object\n         would describe if applied to a sequence of *length* items.\n         It returns a tuple of three integers; respectively these are\n         the *start* and *stop* indices and the *step* or stride\n         length of the slice. Missing or out-of-bounds indices are\n         handled in a manner consistent with regular slices.\n\n   Static method objects\n      Static method objects provide a way of defeating the\n      transformation of function objects to method objects described\n      above. A static method object is a wrapper around any other\n      object, usually a user-defined method object. When a static\n      method object is retrieved from a class or a class instance, the\n      object actually returned is the wrapped object, which is not\n      subject to any further transformation. Static method objects are\n      not themselves callable, although the objects they wrap usually\n      are. Static method objects are created by the built-in\n      ``staticmethod()`` constructor.\n\n   Class method objects\n      A class method object, like a static method object, is a wrapper\n      around another object that alters the way in which that object\n      is retrieved from classes and class instances. The behaviour of\n      class method objects upon such retrieval is described above,\n      under "User-defined methods". Class method objects are created\n      by the built-in ``classmethod()`` constructor.\n',
+ 'try': '\nThe ``try`` statement\n*********************\n\nThe ``try`` statement specifies exception handlers and/or cleanup code\nfor a group of statements:\n\n   try_stmt  ::= try1_stmt | try2_stmt\n   try1_stmt ::= "try" ":" suite\n                 ("except" [expression ["as" target]] ":" suite)+\n                 ["else" ":" suite]\n                 ["finally" ":" suite]\n   try2_stmt ::= "try" ":" suite\n                 "finally" ":" suite\n\nThe ``except`` clause(s) specify one or more exception handlers. When\nno exception occurs in the ``try`` clause, no exception handler is\nexecuted. When an exception occurs in the ``try`` suite, a search for\nan exception handler is started.  This search inspects the except\nclauses in turn until one is found that matches the exception.  An\nexpression-less except clause, if present, must be last; it matches\nany exception.  For an except clause with an expression, that\nexpression is evaluated, and the clause matches the exception if the\nresulting object is "compatible" with the exception.  An object is\ncompatible with an exception if it is the class or a base class of the\nexception object or a tuple containing an item compatible with the\nexception.\n\nIf no except clause matches the exception, the search for an exception\nhandler continues in the surrounding code and on the invocation stack.\n[1]\n\nIf the evaluation of an expression in the header of an except clause\nraises an exception, the original search for a handler is canceled and\na search starts for the new exception in the surrounding code and on\nthe call stack (it is treated as if the entire ``try`` statement\nraised the exception).\n\nWhen a matching except clause is found, the exception is assigned to\nthe target specified after the ``as`` keyword in that except clause,\nif present, and the except clause\'s suite is executed.  All except\nclauses must have an executable block.  When the end of this block is\nreached, execution continues normally after the entire try statement.\n(This means that if two nested handlers exist for the same exception,\nand the exception occurs in the try clause of the inner handler, the\nouter handler will not handle the exception.)\n\nWhen an exception has been assigned using ``as target``, it is cleared\nat the end of the except clause.  This is as if\n\n   except E as N:\n       foo\n\nwas translated to\n\n   except E as N:\n       try:\n           foo\n       finally:\n           del N\n\nThis means the exception must be assigned to a different name to be\nable to refer to it after the except clause.  Exceptions are cleared\nbecause with the traceback attached to them, they form a reference\ncycle with the stack frame, keeping all locals in that frame alive\nuntil the next garbage collection occurs.\n\nBefore an except clause\'s suite is executed, details about the\nexception are stored in the ``sys`` module and can be access via\n``sys.exc_info()``. ``sys.exc_info()`` returns a 3-tuple consisting of\nthe exception class, the exception instance and a traceback object\n(see section *The standard type hierarchy*) identifying the point in\nthe program where the exception occurred.  ``sys.exc_info()`` values\nare restored to their previous values (before the call) when returning\nfrom a function that handled an exception.\n\nThe optional ``else`` clause is executed if and when control flows off\nthe end of the ``try`` clause. [2] Exceptions in the ``else`` clause\nare not handled by the preceding ``except`` clauses.\n\nIf ``finally`` is present, it specifies a \'cleanup\' handler.  The\n``try`` clause is executed, including any ``except`` and ``else``\nclauses.  If an exception occurs in any of the clauses and is not\nhandled, the exception is temporarily saved. The ``finally`` clause is\nexecuted.  If there is a saved exception, it is re-raised at the end\nof the ``finally`` clause. If the ``finally`` clause raises another\nexception or executes a ``return`` or ``break`` statement, the saved\nexception is lost.  The exception information is not available to the\nprogram during execution of the ``finally`` clause.\n\nWhen a ``return``, ``break`` or ``continue`` statement is executed in\nthe ``try`` suite of a ``try``...``finally`` statement, the\n``finally`` clause is also executed \'on the way out.\' A ``continue``\nstatement is illegal in the ``finally`` clause. (The reason is a\nproblem with the current implementation --- this restriction may be\nlifted in the future).\n\nAdditional information on exceptions can be found in section\n*Exceptions*, and information on using the ``raise`` statement to\ngenerate exceptions may be found in section *The raise statement*.\n',
+ 'types': '\nThe standard type hierarchy\n***************************\n\nBelow is a list of the types that are built into Python.  Extension\nmodules (written in C, Java, or other languages, depending on the\nimplementation) can define additional types.  Future versions of\nPython may add types to the type hierarchy (e.g., rational numbers,\nefficiently stored arrays of integers, etc.), although such additions\nwill often be provided via the standard library instead.\n\nSome of the type descriptions below contain a paragraph listing\n\'special attributes.\'  These are attributes that provide access to the\nimplementation and are not intended for general use.  Their definition\nmay change in the future.\n\nNone\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name ``None``.\n   It is used to signify the absence of a value in many situations,\n   e.g., it is returned from functions that don\'t explicitly return\n   anything. Its truth value is false.\n\nNotImplemented\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the built-in name\n   ``NotImplemented``. Numeric methods and rich comparison methods may\n   return this value if they do not implement the operation for the\n   operands provided.  (The interpreter will then try the reflected\n   operation, or some other fallback, depending on the operator.)  Its\n   truth value is true.\n\nEllipsis\n   This type has a single value.  There is a single object with this\n   value. This object is accessed through the literal ``...`` or the\n   built-in name ``Ellipsis``.  Its truth value is true.\n\n``numbers.Number``\n   These are created by numeric literals and returned as results by\n   arithmetic operators and arithmetic built-in functions.  Numeric\n   objects are immutable; once created their value never changes.\n   Python numbers are of course strongly related to mathematical\n   numbers, but subject to the limitations of numerical representation\n   in computers.\n\n   Python distinguishes between integers, floating point numbers, and\n   complex numbers:\n\n   ``numbers.Integral``\n      These represent elements from the mathematical set of integers\n      (positive and negative).\n\n      There are two types of integers:\n\n      Integers (``int``)\n\n         These represent numbers in an unlimited range, subject to\n         available (virtual) memory only.  For the purpose of shift\n         and mask operations, a binary representation is assumed, and\n         negative numbers are represented in a variant of 2\'s\n         complement which gives the illusion of an infinite string of\n         sign bits extending to the left.\n\n      Booleans (``bool``)\n         These represent the truth values False and True.  The two\n         objects representing the values False and True are the only\n         Boolean objects. The Boolean type is a subtype of the integer\n         type, and Boolean values behave like the values 0 and 1,\n         respectively, in almost all contexts, the exception being\n         that when converted to a string, the strings ``"False"`` or\n         ``"True"`` are returned, respectively.\n\n      The rules for integer representation are intended to give the\n      most meaningful interpretation of shift and mask operations\n      involving negative integers.\n\n   ``numbers.Real`` (``float``)\n      These represent machine-level double precision floating point\n      numbers. You are at the mercy of the underlying machine\n      architecture (and C or Java implementation) for the accepted\n      range and handling of overflow. Python does not support single-\n      precision floating point numbers; the savings in processor and\n      memory usage that are usually the reason for using these is\n      dwarfed by the overhead of using objects in Python, so there is\n      no reason to complicate the language with two kinds of floating\n      point numbers.\n\n   ``numbers.Complex`` (``complex``)\n      These represent complex numbers as a pair of machine-level\n      double precision floating point numbers.  The same caveats apply\n      as for floating point numbers. The real and imaginary parts of a\n      complex number ``z`` can be retrieved through the read-only\n      attributes ``z.real`` and ``z.imag``.\n\nSequences\n   These represent finite ordered sets indexed by non-negative\n   numbers. The built-in function ``len()`` returns the number of\n   items of a sequence. When the length of a sequence is *n*, the\n   index set contains the numbers 0, 1, ..., *n*-1.  Item *i* of\n   sequence *a* is selected by ``a[i]``.\n\n   Sequences also support slicing: ``a[i:j]`` selects all items with\n   index *k* such that *i* ``<=`` *k* ``<`` *j*.  When used as an\n   expression, a slice is a sequence of the same type.  This implies\n   that the index set is renumbered so that it starts at 0.\n\n   Some sequences also support "extended slicing" with a third "step"\n   parameter: ``a[i:j:k]`` selects all items of *a* with index *x*\n   where ``x = i + n*k``, *n* ``>=`` ``0`` and *i* ``<=`` *x* ``<``\n   *j*.\n\n   Sequences are distinguished according to their mutability:\n\n   Immutable sequences\n      An object of an immutable sequence type cannot change once it is\n      created.  (If the object contains references to other objects,\n      these other objects may be mutable and may be changed; however,\n      the collection of objects directly referenced by an immutable\n      object cannot change.)\n\n      The following types are immutable sequences:\n\n      Strings\n         The items of a string object are Unicode code units.  A\n         Unicode code unit is represented by a string object of one\n         item and can hold either a 16-bit or 32-bit value\n         representing a Unicode ordinal (the maximum value for the\n         ordinal is given in ``sys.maxunicode``, and depends on how\n         Python is configured at compile time).  Surrogate pairs may\n         be present in the Unicode object, and will be reported as two\n         separate items.  The built-in functions ``chr()`` and\n         ``ord()`` convert between code units and nonnegative integers\n         representing the Unicode ordinals as defined in the Unicode\n         Standard 3.0. Conversion from and to other encodings are\n         possible through the string method ``encode()``.\n\n      Tuples\n         The items of a tuple are arbitrary Python objects. Tuples of\n         two or more items are formed by comma-separated lists of\n         expressions.  A tuple of one item (a \'singleton\') can be\n         formed by affixing a comma to an expression (an expression by\n         itself does not create a tuple, since parentheses must be\n         usable for grouping of expressions).  An empty tuple can be\n         formed by an empty pair of parentheses.\n\n      Bytes\n         A bytes object is an immutable array.  The items are 8-bit\n         bytes, represented by integers in the range 0 <= x < 256.\n         Bytes literals (like ``b\'abc\'`` and the built-in function\n         ``bytes()`` can be used to construct bytes objects.  Also,\n         bytes objects can be decoded to strings via the ``decode()``\n         method.\n\n   Mutable sequences\n      Mutable sequences can be changed after they are created.  The\n      subscription and slicing notations can be used as the target of\n      assignment and ``del`` (delete) statements.\n\n      There are currently two intrinsic mutable sequence types:\n\n      Lists\n         The items of a list are arbitrary Python objects.  Lists are\n         formed by placing a comma-separated list of expressions in\n         square brackets. (Note that there are no special cases needed\n         to form lists of length 0 or 1.)\n\n      Byte Arrays\n         A bytearray object is a mutable array. They are created by\n         the built-in ``bytearray()`` constructor.  Aside from being\n         mutable (and hence unhashable), byte arrays otherwise provide\n         the same interface and functionality as immutable bytes\n         objects.\n\n      The extension module ``array`` provides an additional example of\n      a mutable sequence type, as does the ``collections`` module.\n\nSet types\n   These represent unordered, finite sets of unique, immutable\n   objects. As such, they cannot be indexed by any subscript. However,\n   they can be iterated over, and the built-in function ``len()``\n   returns the number of items in a set. Common uses for sets are fast\n   membership testing, removing duplicates from a sequence, and\n   computing mathematical operations such as intersection, union,\n   difference, and symmetric difference.\n\n   For set elements, the same immutability rules apply as for\n   dictionary keys. Note that numeric types obey the normal rules for\n   numeric comparison: if two numbers compare equal (e.g., ``1`` and\n   ``1.0``), only one of them can be contained in a set.\n\n   There are currently two intrinsic set types:\n\n   Sets\n      These represent a mutable set. They are created by the built-in\n      ``set()`` constructor and can be modified afterwards by several\n      methods, such as ``add()``.\n\n   Frozen sets\n      These represent an immutable set.  They are created by the\n      built-in ``frozenset()`` constructor.  As a frozenset is\n      immutable and *hashable*, it can be used again as an element of\n      another set, or as a dictionary key.\n\nMappings\n   These represent finite sets of objects indexed by arbitrary index\n   sets. The subscript notation ``a[k]`` selects the item indexed by\n   ``k`` from the mapping ``a``; this can be used in expressions and\n   as the target of assignments or ``del`` statements. The built-in\n   function ``len()`` returns the number of items in a mapping.\n\n   There is currently a single intrinsic mapping type:\n\n   Dictionaries\n      These represent finite sets of objects indexed by nearly\n      arbitrary values.  The only types of values not acceptable as\n      keys are values containing lists or dictionaries or other\n      mutable types that are compared by value rather than by object\n      identity, the reason being that the efficient implementation of\n      dictionaries requires a key\'s hash value to remain constant.\n      Numeric types used for keys obey the normal rules for numeric\n      comparison: if two numbers compare equal (e.g., ``1`` and\n      ``1.0``) then they can be used interchangeably to index the same\n      dictionary entry.\n\n      Dictionaries are mutable; they can be created by the ``{...}``\n      notation (see section *Dictionary displays*).\n\n      The extension modules ``dbm.ndbm`` and ``dbm.gnu`` provide\n      additional examples of mapping types, as does the\n      ``collections`` module.\n\nCallable types\n   These are the types to which the function call operation (see\n   section *Calls*) can be applied:\n\n   User-defined functions\n      A user-defined function object is created by a function\n      definition (see section *Function definitions*).  It should be\n      called with an argument list containing the same number of items\n      as the function\'s formal parameter list.\n\n      Special attributes:\n\n      +---------------------------+---------------------------------+-------------+\n      | Attribute                 | Meaning                         |             |\n      +===========================+=================================+=============+\n      | ``__doc__``               | The function\'s documentation    | Writable    |\n      |                           | string, or ``None`` if          |             |\n      |                           | unavailable                     |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__name__``              | The function\'s name             | Writable    |\n      +---------------------------+---------------------------------+-------------+\n      | ``__module__``            | The name of the module the      | Writable    |\n      |                           | function was defined in, or     |             |\n      |                           | ``None`` if unavailable.        |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__defaults__``          | A tuple containing default      | Writable    |\n      |                           | argument values for those       |             |\n      |                           | arguments that have defaults,   |             |\n      |                           | or ``None`` if no arguments     |             |\n      |                           | have a default value            |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__code__``              | The code object representing    | Writable    |\n      |                           | the compiled function body.     |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__globals__``           | A reference to the dictionary   | Read-only   |\n      |                           | that holds the function\'s       |             |\n      |                           | global variables --- the global |             |\n      |                           | namespace of the module in      |             |\n      |                           | which the function was defined. |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__dict__``              | The namespace supporting        | Writable    |\n      |                           | arbitrary function attributes.  |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__closure__``           | ``None`` or a tuple of cells    | Read-only   |\n      |                           | that contain bindings for the   |             |\n      |                           | function\'s free variables.      |             |\n      +---------------------------+---------------------------------+-------------+\n      | ``__annotations__``       | A dict containing annotations   | Writable    |\n      |                           | of parameters.

Regular attribute dot-notation is used to get and\n      set such attributes. *Note that the current implementation only\n      supports function attributes on user-defined functions. Function\n      attributes on built-in functions may be supported in the\n      future.*\n\n      Additional information about a function\'s definition can be\n      retrieved from its code object; see the description of internal\n      types below.\n\n   Instance methods\n      An instance method object combines a class, a class instance and\n      any callable object (normally a user-defined function).\n\n      Special read-only attributes: ``__self__`` is the class instance\n      object, ``__func__`` is the function object; ``__doc__`` is the\n      method\'s documentation (same as ``__func__.__doc__``);\n      ``__name__`` is the method name (same as ``__func__.__name__``);\n      ``__module__`` is the name of the module the method was defined\n      in, or ``None`` if unavailable.\n\n      Methods also support accessing (but not setting) the arbitrary\n      function attributes on the underlying function object.\n\n      User-defined method objects may be created when getting an\n      attribute of a class (perhaps via an instance of that class), if\n      that attribute is a user-defined function object or a class\n      method object.\n\n      When an instance method object is created by retrieving a user-\n      defined function object from a class via one of its instances,\n      its ``__self__`` attribute is the instance, and the method\n      object is said to be bound.  The new method\'s ``__func__``\n      attribute is the original function object.\n\n      When a user-defined method object is created by retrieving\n      another method object from a class or instance, the behaviour is\n      the same as for a function object, except that the ``__func__``\n      attribute of the new instance is not the original method object\n      but its ``__func__`` attribute.\n\n      When an instance method object is created by retrieving a class\n      method object from a class or instance, its ``__self__``\n      attribute is the class itself, and its ``__func__`` attribute is\n      the function object underlying the class method.\n\n      When an instance method object is called, the underlying\n      function (``__func__``) is called, inserting the class instance\n      (``__self__``) in front of the argument list.  For instance,\n      when ``C`` is a class which contains a definition for a function\n      ``f()``, and ``x`` is an instance of ``C``, calling ``x.f(1)``\n      is equivalent to calling ``C.f(x, 1)``.\n\n      When an instance method object is derived from a class method\n      object, the "class instance" stored in ``__self__`` will\n      actually be the class itself, so that calling either ``x.f(1)``\n      or ``C.f(1)`` is equivalent to calling ``f(C,1)`` where ``f`` is\n      the underlying function.\n\n      Note that the transformation from function object to instance\n      method object happens each time the attribute is retrieved from\n      the instance.  In some cases, a fruitful optimization is to\n      assign the attribute to a local variable and call that local\n      variable. Also notice that this transformation only happens for\n      user-defined functions; other callable objects (and all non-\n      callable objects) are retrieved without transformation.  It is\n      also important to note that user-defined functions which are\n      attributes of a class instance are not converted to bound\n      methods; this *only* happens when the function is an attribute\n      of the class.\n\n   Generator functions\n      A function or method which uses the ``yield`` statement (see\n      section *The yield statement*) is called a *generator function*.\n      Such a function, when called, always returns an iterator object\n      which can be used to execute the body of the function:  calling\n      the iterator\'s ``__next__()`` method will cause the function to\n      execute until it provides a value using the ``yield`` statement.\n      When the function executes a ``return`` statement or falls off\n      the end, a ``StopIteration`` exception is raised and the\n      iterator will have reached the end of the set of values to be\n      returned.\n\n   Built-in functions\n      A built-in function object is a wrapper around a C function.\n      Examples of built-in functions are ``len()`` and ``math.sin()``\n      (``math`` is a standard built-in module). The number and type of\n      the arguments are determined by the C function. Special read-\n      only attributes: ``__doc__`` is the function\'s documentation\n      string, or ``None`` if unavailable; ``__name__`` is the\n      function\'s name; ``__self__`` is set to ``None`` (but see the\n      next item); ``__module__`` is the name of the module the\n      function was defined in or ``None`` if unavailable.\n\n   Built-in methods\n      This is really a different disguise of a built-in function, this\n      time containing an object passed to the C function as an\n      implicit extra argument.  An example of a built-in method is\n      ``alist.append()``, assuming *alist* is a list object. In this\n      case, the special read-only attribute ``__self__`` is set to the\n      object denoted by *alist*.\n\n   Classes\n      Classes are callable.  These objects normally act as factories\n      for new instances of themselves, but variations are possible for\n      class types that override ``__new__()``.  The arguments of the\n      call are passed to ``__new__()`` and, in the typical case, to\n      ``__init__()`` to initialize the new instance.\n\n   Class Instances\n      Instances of arbitrary classes can be made callable by defining\n      a ``__call__()`` method in their class.\n\nModules\n   Modules are imported by the ``import`` statement (see section *The\n   import statement*). A module object has a namespace implemented by\n   a dictionary object (this is the dictionary referenced by the\n   __globals__ attribute of functions defined in the module).\n   Attribute references are translated to lookups in this dictionary,\n   e.g., ``m.x`` is equivalent to ``m.__dict__["x"]``. A module object\n   does not contain the code object used to initialize the module\n   (since it isn\'t needed once the initialization is done).\n\n   Attribute assignment updates the module\'s namespace dictionary,\n   e.g., ``m.x = 1`` is equivalent to ``m.__dict__["x"] = 1``.\n\n   Special read-only attribute: ``__dict__`` is the module\'s namespace\n   as a dictionary object.\n\n   **CPython implementation detail:** Because of the way CPython\n   clears module dictionaries, the module dictionary will be cleared\n   when the module falls out of scope even if the dictionary still has\n   live references.  To avoid this, copy the dictionary or keep the\n   module around while using its dictionary directly.\n\n   Predefined (writable) attributes: ``__name__`` is the module\'s\n   name; ``__doc__`` is the module\'s documentation string, or ``None``\n   if unavailable; ``__file__`` is the pathname of the file from which\n   the module was loaded, if it was loaded from a file. The\n   ``__file__`` attribute is not present for C modules that are\n   statically linked into the interpreter; for extension modules\n   loaded dynamically from a shared library, it is the pathname of the\n   shared library file.\n\nCustom classes\n   Custom class types are typically created by class definitions (see\n   section *Class definitions*).  A class has a namespace implemented\n   by a dictionary object. Class attribute references are translated\n   to lookups in this dictionary, e.g., ``C.x`` is translated to\n   ``C.__dict__["x"]`` (although there are a number of hooks which\n   allow for other means of locating attributes). When the attribute\n   name is not found there, the attribute search continues in the base\n   classes. This search of the base classes uses the C3 method\n   resolution order which behaves correctly even in the presence of\n   \'diamond\' inheritance structures where there are multiple\n   inheritance paths leading back to a common ancestor. Additional\n   details on the C3 MRO used by Python can be found in the\n   documentation accompanying the 2.3 release at\n   http://www.python.org/download/releases/2.3/mro/.\n\n   When a class attribute reference (for class ``C``, say) would yield\n   a class method object, it is transformed into an instance method\n   object whose ``__self__`` attributes is ``C``.  When it would yield\n   a static method object, it is transformed into the object wrapped\n   by the static method object. See section *Implementing Descriptors*\n   for another way in which attributes retrieved from a class may\n   differ from those actually contained in its ``__dict__``.\n\n   Class attribute assignments update the class\'s dictionary, never\n   the dictionary of a base class.\n\n   A class object can be called (see above) to yield a class instance\n   (see below).\n\n   Special attributes: ``__name__`` is the class name; ``__module__``\n   is the module name in which the class was defined; ``__dict__`` is\n   the dictionary containing the class\'s namespace; ``__bases__`` is a\n   tuple (possibly empty or a singleton) containing the base classes,\n   in the order of their occurrence in the base class list;\n   ``__doc__`` is the class\'s documentation string, or None if\n   undefined.\n\nClass instances\n   A class instance is created by calling a class object (see above).\n   A class instance has a namespace implemented as a dictionary which\n   is the first place in which attribute references are searched.\n   When an attribute is not found there, and the instance\'s class has\n   an attribute by that name, the search continues with the class\n   attributes.  If a class attribute is found that is a user-defined\n   function object, it is transformed into an instance method object\n   whose ``__self__`` attribute is the instance.  Static method and\n   class method objects are also transformed; see above under\n   "Classes".  See section *Implementing Descriptors* for another way\n   in which attributes of a class retrieved via its instances may\n   differ from the objects actually stored in the class\'s\n   ``__dict__``.  If no class attribute is found, and the object\'s\n   class has a ``__getattr__()`` method, that is called to satisfy the\n   lookup.\n\n   Attribute assignments and deletions update the instance\'s\n   dictionary, never a class\'s dictionary.  If the class has a\n   ``__setattr__()`` or ``__delattr__()`` method, this is called\n   instead of updating the instance dictionary directly.\n\n   Class instances can pretend to be numbers, sequences, or mappings\n   if they have methods with certain special names.  See section\n   *Special method names*.\n\n   Special attributes: ``__dict__`` is the attribute dictionary;\n   ``__class__`` is the instance\'s class.\n\nI/O objects (also known as file objects)\n   A *file object* represents an open file.  Various shortcuts are\n   available to create file objects: the ``open()`` built-in function,\n   and also ``os.popen()``, ``os.fdopen()``, and the ``makefile()``\n   method of socket objects (and perhaps by other functions or methods\n   provided by extension modules).\n\n   The objects ``sys.stdin``, ``sys.stdout`` and ``sys.stderr`` are\n   initialized to file objects corresponding to the interpreter\'s\n   standard input, output and error streams; they are all open in text\n   mode and therefore follow the interface defined by the\n   ``io.TextIOBase`` abstract class.\n\nInternal types\n   A few types used internally by the interpreter are exposed to the\n   user. Their definitions may change with future versions of the\n   interpreter, but they are mentioned here for completeness.\n\n   Code objects\n      Code objects represent *byte-compiled* executable Python code,\n      or *bytecode*. The difference between a code object and a\n      function object is that the function object contains an explicit\n      reference to the function\'s globals (the module in which it was\n      defined), while a code object contains no context; also the\n      default argument values are stored in the function object, not\n      in the code object (because they represent values calculated at\n      run-time).  Unlike function objects, code objects are immutable\n      and contain no references (directly or indirectly) to mutable\n      objects.\n\n      Special read-only attributes: ``co_name`` gives the function\n      name; ``co_argcount`` is the number of positional arguments\n      (including arguments with default values); ``co_nlocals`` is the\n      number of local variables used by the function (including\n      arguments); ``co_varnames`` is a tuple containing the names of\n      the local variables (starting with the argument names);\n      ``co_cellvars`` is a tuple containing the names of local\n      variables that are referenced by nested functions;\n      ``co_freevars`` is a tuple containing the names of free\n      variables; ``co_code`` is a string representing the sequence of\n      bytecode instructions; ``co_consts`` is a tuple containing the\n      literals used by the bytecode; ``co_names`` is a tuple\n      containing the names used by the bytecode; ``co_filename`` is\n      the filename from which the code was compiled;\n      ``co_firstlineno`` is the first line number of the function;\n      ``co_lnotab`` is a string encoding the mapping from bytecode\n      offsets to line numbers (for details see the source code of the\n      interpreter); ``co_stacksize`` is the required stack size\n      (including local variables); ``co_flags`` is an integer encoding\n      a number of flags for the interpreter.\n\n      The following flag bits are defined for ``co_flags``: bit\n      ``0x04`` is set if the function uses the ``*arguments`` syntax\n      to accept an arbitrary number of positional arguments; bit\n      ``0x08`` is set if the function uses the ``**keywords`` syntax\n      to accept arbitrary keyword arguments; bit ``0x20`` is set if\n      the function is a generator.\n\n      Future feature declarations (``from __future__ import\n      division``) also use bits in ``co_flags`` to indicate whether a\n      code object was compiled with a particular feature enabled: bit\n      ``0x2000`` is set if the function was compiled with future\n      division enabled; bits ``0x10`` and ``0x1000`` were used in\n      earlier versions of Python.\n\n      Other bits in ``co_flags`` are reserved for internal use.\n\n      If a code object represents a function, the first item in\n      ``co_consts`` is the documentation string of the function, or\n      ``None`` if undefined.\n\n   Frame objects\n      Frame objects represent execution frames.  They may occur in\n      traceback objects (see below).\n\n      Special read-only attributes: ``f_back`` is to the previous\n      stack frame (towards the caller), or ``None`` if this is the\n      bottom stack frame; ``f_code`` is the code object being executed\n      in this frame; ``f_locals`` is the dictionary used to look up\n      local variables; ``f_globals`` is used for global variables;\n      ``f_builtins`` is used for built-in (intrinsic) names;\n      ``f_lasti`` gives the precise instruction (this is an index into\n      the bytecode string of the code object).\n\n      Special writable attributes: ``f_trace``, if not ``None``, is a\n      function called at the start of each source code line (this is\n      used by the debugger); ``f_lineno`` is the current line number\n      of the frame --- writing to this from within a trace function\n      jumps to the given line (only for the bottom-most frame).  A\n      debugger can implement a Jump command (aka Set Next Statement)\n      by writing to f_lineno.\n\n   Traceback objects\n      Traceback objects represent a stack trace of an exception.  A\n      traceback object is created when an exception occurs.  When the\n      search for an exception handler unwinds the execution stack, at\n      each unwound level a traceback object is inserted in front of\n      the current traceback.  When an exception handler is entered,\n      the stack trace is made available to the program. (See section\n      *The try statement*.) It is accessible as the third item of the\n      tuple returned by ``sys.exc_info()``. When the program contains\n      no suitable handler, the stack trace is written (nicely\n      formatted) to the standard error stream; if the interpreter is\n      interactive, it is also made available to the user as\n      ``sys.last_traceback``.\n\n      Special read-only attributes: ``tb_next`` is the next level in\n      the stack trace (towards the frame where the exception\n      occurred), or ``None`` if there is no next level; ``tb_frame``\n      points to the execution frame of the current level;\n      ``tb_lineno`` gives the line number where the exception\n      occurred; ``tb_lasti`` indicates the precise instruction.  The\n      line number and last instruction in the traceback may differ\n      from the line number of its frame object if the exception\n      occurred in a ``try`` statement with no matching except clause\n      or with a finally clause.\n\n   Slice objects\n      Slice objects are used to represent slices for ``__getitem__()``\n      methods.  They are also created by the built-in ``slice()``\n      function.\n\n      Special read-only attributes: ``start`` is the lower bound;\n      ``stop`` is the upper bound; ``step`` is the step value; each is\n      ``None`` if omitted. These attributes can have any type.\n\n      Slice objects support one method:\n\n      slice.indices(self, length)\n\n         This method takes a single integer argument *length* and\n         computes information about the slice that the slice object\n         would describe if applied to a sequence of *length* items.\n         It returns a tuple of three integers; respectively these are\n         the *start* and *stop* indices and the *step* or stride\n         length of the slice. Missing or out-of-bounds indices are\n         handled in a manner consistent with regular slices.\n\n   Static method objects\n      Static method objects provide a way of defeating the\n      transformation of function objects to method objects described\n      above. A static method object is a wrapper around any other\n      object, usually a user-defined method object. When a static\n      method object is retrieved from a class or a class instance, the\n      object actually returned is the wrapped object, which is not\n      subject to any further transformation. Static method objects are\n      not themselves callable, although the objects they wrap usually\n      are. Static method objects are created by the built-in\n      ``staticmethod()`` constructor.\n\n   Class method objects\n      A class method object, like a static method object, is a wrapper\n      around another object that alters the way in which that object\n      is retrieved from classes and class instances. The behaviour of\n      class method objects upon such retrieval is described above,\n      under "User-defined methods". Class method objects are created\n      by the built-in ``classmethod()`` constructor.\n',
  'typesfunctions': '\nFunctions\n*********\n\nFunction objects are created by function definitions.  The only\noperation on a function object is to call it: ``func(argument-list)``.\n\nThere are really two flavors of function objects: built-in functions\nand user-defined functions.  Both support the same operation (to call\nthe function), but the implementation is different, hence the\ndifferent object types.\n\nSee *Function definitions* for more information.\n',
- 'typesmapping': '\nMapping Types --- ``dict``\n**************************\n\nA *mapping* object maps *hashable* values to arbitrary objects.\nMappings are mutable objects.  There is currently only one standard\nmapping type, the *dictionary*.  (For other containers see the built\nin ``list``, ``set``, and ``tuple`` classes, and the ``collections``\nmodule.)\n\nA dictionary\'s keys are *almost* arbitrary values.  Values that are\nnot *hashable*, that is, values containing lists, dictionaries or\nother mutable types (that are compared by value rather than by object\nidentity) may not be used as keys.  Numeric types used for keys obey\nthe normal rules for numeric comparison: if two numbers compare equal\n(such as ``1`` and ``1.0``) then they can be used interchangeably to\nindex the same dictionary entry.  (Note however, that since computers\nstore floating-point numbers as approximations it is usually unwise to\nuse them as dictionary keys.)\n\nDictionaries can be created by placing a comma-separated list of\n``key: value`` pairs within braces, for example: ``{\'jack\': 4098,\n\'sjoerd\': 4127}`` or ``{4098: \'jack\', 4127: \'sjoerd\'}``, or by the\n``dict`` constructor.\n\nclass class dict([arg])\n\n   Return a new dictionary initialized from an optional positional\n   argument or from a set of keyword arguments.  If no arguments are\n   given, return a new empty dictionary.  If the positional argument\n   *arg* is a mapping object, return a dictionary mapping the same\n   keys to the same values as does the mapping object.  Otherwise the\n   positional argument must be a sequence, a container that supports\n   iteration, or an iterator object.  The elements of the argument\n   must each also be of one of those kinds, and each must in turn\n   contain exactly two objects.  The first is used as a key in the new\n   dictionary, and the second as the key\'s value.  If a given key is\n   seen more than once, the last value associated with it is retained\n   in the new dictionary.\n\n   If keyword arguments are given, the keywords themselves with their\n   associated values are added as items to the dictionary.  If a key\n   is specified both in the positional argument and as a keyword\n   argument, the value associated with the keyword is retained in the\n   dictionary.  For example, these all return a dictionary equal to\n   ``{"one": 2, "two": 3}``:\n\n   * ``dict(one=2, two=3)``\n\n   * ``dict({\'one\': 2, \'two\': 3})``\n\n   * ``dict(zip((\'one\', \'two\'), (2, 3)))``\n\n   * ``dict([[\'two\', 3], [\'one\', 2]])``\n\n   The first example only works for keys that are valid Python\n   identifiers; the others work with any valid keys.\n\n   These are the operations that dictionaries support (and therefore,\n   custom mapping types should support too):\n\n   len(d)\n\n      Return the number of items in the dictionary *d*.\n\n   d[key]\n\n      Return the item of *d* with key *key*.  Raises a ``KeyError`` if\n      *key* is not in the map.\n\n      If a subclass of dict defines a method ``__missing__()``, if the\n      key *key* is not present, the ``d[key]`` operation calls that\n      method with the key *key* as argument.  The ``d[key]`` operation\n      then returns or raises whatever is returned or raised by the\n      ``__missing__(key)`` call if the key is not present. No other\n      operations or methods invoke ``__missing__()``. If\n      ``__missing__()`` is not defined, ``KeyError`` is raised.\n      ``__missing__()`` must be a method; it cannot be an instance\n      variable. For an example, see ``collections.defaultdict``.\n\n   d[key] = value\n\n      Set ``d[key]`` to *value*.\n\n   del d[key]\n\n      Remove ``d[key]`` from *d*.  Raises a ``KeyError`` if *key* is\n      not in the map.\n\n   key in d\n\n      Return ``True`` if *d* has a key *key*, else ``False``.\n\n   key not in d\n\n      Equivalent to ``not key in d``.\n\n   iter(d)\n\n      Return an iterator over the keys of the dictionary.  This is a\n      shortcut for ``iterkeys()``.\n\n   clear()\n\n      Remove all items from the dictionary.\n\n   copy()\n\n      Return a shallow copy of the dictionary.\n\n   classmethod fromkeys(seq[, value])\n\n      Create a new dictionary with keys from *seq* and values set to\n      *value*.\n\n      ``fromkeys()`` is a class method that returns a new dictionary.\n      *value* defaults to ``None``.\n\n   get(key[, default])\n\n      Return the value for *key* if *key* is in the dictionary, else\n      *default*. If *default* is not given, it defaults to ``None``,\n      so that this method never raises a ``KeyError``.\n\n   items()\n\n      Return a new view of the dictionary\'s items (``(key, value)``\n      pairs).  See below for documentation of view objects.\n\n   keys()\n\n      Return a new view of the dictionary\'s keys.  See below for\n      documentation of view objects.\n\n   pop(key[, default])\n\n      If *key* is in the dictionary, remove it and return its value,\n      else return *default*.  If *default* is not given and *key* is\n      not in the dictionary, a ``KeyError`` is raised.\n\n   popitem()\n\n      Remove and return an arbitrary ``(key, value)`` pair from the\n      dictionary.\n\n      ``popitem()`` is useful to destructively iterate over a\n      dictionary, as often used in set algorithms.  If the dictionary\n      is empty, calling ``popitem()`` raises a ``KeyError``.\n\n   setdefault(key[, default])\n\n      If *key* is in the dictionary, return its value.  If not, insert\n      *key* with a value of *default* and return *default*.  *default*\n      defaults to ``None``.\n\n   update([other])\n\n      Update the dictionary with the key/value pairs from *other*,\n      overwriting existing keys.  Return ``None``.\n\n         ``update()`` accepts either another dictionary object or an\n         iterable of key/value pairs (as a tuple or other iterable of\n         length two).  If keyword arguments are specified, the\n         dictionary is then is updated with those key/value pairs:\n         ``d.update(red=1, blue=2)``.\n\n   values()\n\n      Return a new view of the dictionary\'s values.  See below for\n      documentation of view objects.\n\n\nDictionary view objects\n=======================\n\nThe objects returned by ``dict.keys()``, ``dict.values()`` and\n``dict.items()`` are *view objects*.  They provide a dynamic view on\nthe dictionary\'s entries, which means that when the dictionary\nchanges, the view reflects these changes.\n\nDictionary views can be iterated over to yield their respective data,\nand support membership tests:\n\nlen(dictview)\n\n   Return the number of entries in the dictionary.\n\niter(dictview)\n\n   Return an iterator over the keys, values or items (represented as\n   tuples of ``(key, value)``) in the dictionary.\n\n   Keys and values are iterated over in an arbitrary order which is\n   non-random, varies across Python implementations, and depends on\n   the dictionary\'s history of insertions and deletions. If keys,\n   values and items views are iterated over with no intervening\n   modifications to the dictionary, the order of items will directly\n   correspond.  This allows the creation of ``(value, key)`` pairs\n   using ``zip()``: ``pairs = zip(d.values(), d.keys())``.  Another\n   way to create the same list is ``pairs = [(v, k) for (k, v) in\n   d.items()]``.\n\n   Iterating views while adding or deleting entries in the dictionary\n   may raise a ``RuntimeError`` or fail to iterate over all entries.\n\nx in dictview\n\n   Return ``True`` if *x* is in the underlying dictionary\'s keys,\n   values or items (in the latter case, *x* should be a ``(key,\n   value)`` tuple).\n\nKeys views are set-like since their entries are unique and hashable.\nIf all values are hashable, so that (key, value) pairs are unique and\nhashable, then the items view is also set-like.  (Values views are not\ntreated as set-like since the entries are generally not unique.)  Then\nthese set operations are available ("other" refers either to another\nview or a set):\n\ndictview & other\n\n   Return the intersection of the dictview and the other object as a\n   new set.\n\ndictview | other\n\n   Return the union of the dictview and the other object as a new set.\n\ndictview - other\n\n   Return the difference between the dictview and the other object\n   (all elements in *dictview* that aren\'t in *other*) as a new set.\n\ndictview ^ other\n\n   Return the symmetric difference (all elements either in *dictview*\n   or *other*, but not in both) of the dictview and the other object\n   as a new set.\n\nAn example of dictionary view usage:\n\n   >>> dishes = {\'eggs\': 2, \'sausage\': 1, \'bacon\': 1, \'spam\': 500}\n   >>> keys = dishes.keys()\n   >>> values = dishes.values()\n\n   >>> # iteration\n   >>> n = 0\n   >>> for val in values:\n   ...     n += val\n   >>> print(n)\n   504\n\n   >>> # keys and values are iterated over in the same order\n   >>> list(keys)\n   [\'eggs\', \'bacon\', \'sausage\', \'spam\']\n   >>> list(values)\n   [2, 1, 1, 500]\n\n   >>> # view objects are dynamic and reflect dict changes\n   >>> del dishes[\'eggs\']\n   >>> del dishes[\'sausage\']\n   >>> list(keys)\n   [\'spam\', \'bacon\']\n\n   >>> # set operations\n   >>> keys & {\'eggs\', \'bacon\', \'salad\'}\n   {\'bacon\'}\n',

(Note however, that since computers\nstore floating-point numbers as approximations it is usually unwise to\nuse them as dictionary keys.)\n\nDictionaries can be created by placing a comma-separated list of\n``key: value`` pairs within braces, for example: ``{\'jack\': 4098,\n\'sjoerd\': 4127}`` or ``{4098: \'jack\', 4127: \'sjoerd\'}``, or by the\n``dict`` constructor.\n\nclass class dict([arg])\n\n   Return a new dictionary initialized from an optional positional\n   argument or from a set of keyword arguments.  If no arguments are\n   given, return a new empty dictionary.  If the positional argument\n   *arg* is a mapping object, return a dictionary mapping the same\n   keys to the same values as does the mapping object.  Otherwise the\n   positional argument must be a sequence, a container that supports\n   iteration, or an iterator object.  The elements of the argument\n   must each also be of one of those kinds, and each must in turn\n   contain exactly two objects.  The first is used as a key in the new\n   dictionary, and the second as the key\'s value.  If a given key is\n   seen more than once, the last value associated with it is retained\n   in the new dictionary.\n\n   If keyword arguments are given, the keywords themselves with their\n   associated values are added as items to the dictionary.  If a key\n   is specified both in the positional argument and as a keyword\n   argument, the value associated with the keyword is retained in the\n   dictionary.  For example, these all return a dictionary equal to\n   ``{"one": 1, "two": 2}``:\n\n   * ``dict(one=1, two=2)``\n\n   * ``dict({\'one\': 1, \'two\': 2})``\n\n   * ``dict(zip((\'one\', \'two\'), (1, 2)))``\n\n   * ``dict([[\'two\', 2], [\'one\', 1]])``\n\n   The first example only works for keys that are valid Python\n   identifiers; the others work with any valid keys.\n\n   These are the operations that dictionaries support (and therefore,\n   custom mapping types should support too):\n\n   len(d)\n\n      Return the number of items in the dictionary *d*.\n\n   d[key]\n\n      Return the item of *d* with key *key*.  Raises a ``KeyError`` if\n      *key* is not in the map.\n\n      If a subclass of dict defines a method ``__missing__()``, if the\n      key *key* is not present, the ``d[key]`` operation calls that\n      method with the key *key* as argument.  The ``d[key]`` operation\n      then returns or raises whatever is returned or raised by the\n      ``__missing__(key)`` call if the key is not present. No other\n      operations or methods invoke ``__missing__()``. If\n      ``__missing__()`` is not defined, ``KeyError`` is raised.\n      ``__missing__()`` must be a method; it cannot be an instance\n      variable:\n\n         >>> class Counter(dict):\n         ...     def __missing__(self, key):\n         ...         return 0\n         >>> c = Counter()\n         >>> c[\'red\']\n         0\n         >>> c[\'red\'] += 1\n         >>> c[\'red\']\n         1\n\n      See ``collections.Counter`` for a complete implementation\n      including other methods helpful for accumulating and managing\n      tallies.\n\n   d[key] = value\n\n      Set ``d[key]`` to *value*.\n\n   del d[key]\n\n      Remove ``d[key]`` from *d*.  Raises a ``KeyError`` if *key* is\n      not in the map.\n\n   key in d\n\n      Return ``True`` if *d* has a key *key*, else ``False``.\n\n   key not in d\n\n      Equivalent to ``not key in d``.\n\n   iter(d)\n\n      Return an iterator over the keys of the dictionary.  This is a\n      shortcut for ``iter(d.keys())``.\n\n   clear()\n\n      Remove all items from the dictionary.\n\n   copy()\n\n      Return a shallow copy of the dictionary.\n\n   classmethod fromkeys(seq[, value])\n\n      Create a new dictionary with keys from *seq* and values set to\n      *value*.\n\n      ``fromkeys()`` is a class method that returns a new dictionary.\n      *value* defaults to ``None``.\n\n   get(key[, default])\n\n      Return the value for *key* if *key* is in the dictionary, else\n      *default*. If *default* is not given, it defaults to ``None``,\n      so that this method never raises a ``KeyError``.\n\n   items()\n\n      Return a new view of the dictionary\'s items (``(key, value)``\n      pairs).  See below for documentation of view objects.\n\n   keys()\n\n      Return a new view of the dictionary\'s keys.  See below for\n      documentation of view objects.\n\n   pop(key[, default])\n\n      If *key* is in the dictionary, remove it and return its value,\n      else return *default*.  If *default* is not given and *key* is\n      not in the dictionary, a ``KeyError`` is raised.\n\n   popitem()\n\n      Remove and return an arbitrary ``(key, value)`` pair from the\n      dictionary.\n\n      ``popitem()`` is useful to destructively iterate over a\n      dictionary, as often used in set algorithms.  If the dictionary\n      is empty, calling ``popitem()`` raises a ``KeyError``.\n\n   setdefault(key[, default])\n\n      If *key* is in the dictionary, return its value.  If not, insert\n      *key* with a value of *default* and return *default*.  *default*\n      defaults to ``None``.\n\n   update([other])\n\n      Update the dictionary with the key/value pairs from *other*,\n      overwriting existing keys.  Return ``None``.\n\n      ``update()`` accepts either another dictionary object or an\n      iterable of key/value pairs (as tuples or other iterables of\n      length two).  If keyword arguments are specified, the dictionary\n      is then updated with those key/value pairs: ``d.update(red=1,\n      blue=2)``.\n\n   values()\n\n      Return a new view of the dictionary\'s values.  See below for\n      documentation of view objects.\n\n\nDictionary view objects\n=======================\n\nThe objects returned by ``dict.keys()``, ``dict.values()`` and\n``dict.items()`` are *view objects*.  They provide a dynamic view on\nthe dictionary\'s entries, which means that when the dictionary\nchanges, the view reflects these changes.\n\nDictionary views can be iterated over to yield their respective data,\nand support membership tests:\n\nlen(dictview)\n\n   Return the number of entries in the dictionary.\n\niter(dictview)\n\n   Return an iterator over the keys, values or items (represented as\n   tuples of ``(key, value)``) in the dictionary.\n\n   Keys and values are iterated over in an arbitrary order which is\n   non-random, varies across Python implementations, and depends on\n   the dictionary\'s history of insertions and deletions. If keys,\n   values and items views are iterated over with no intervening\n   modifications to the dictionary, the order of items will directly\n   correspond.  This allows the creation of ``(value, key)`` pairs\n   using ``zip()``: ``pairs = zip(d.values(), d.keys())``.  Another\n   way to create the same list is ``pairs = [(v, k) for (k, v) in\n   d.items()]``.\n\n   Iterating views while adding or deleting entries in the dictionary\n   may raise a ``RuntimeError`` or fail to iterate over all entries.\n\nx in dictview\n\n   Return ``True`` if *x* is in the underlying dictionary\'s keys,\n   values or items (in the latter case, *x* should be a ``(key,\n   value)`` tuple).\n\nKeys views are set-like since their entries are unique and hashable.\nIf all values are hashable, so that ``(key, value)`` pairs are unique\nand hashable, then the items view is also set-like.  (Values views are\nnot treated as set-like since the entries are generally not unique.)\nFor set-like views, all of the operations defined for the abstract\nbase class ``collections.Set`` are available (for example, ``==``,\n``<``, or ``^``).\n\nAn example of dictionary view usage:\n\n   >>> dishes = {\'eggs\': 2, \'sausage\': 1, \'bacon\': 1, \'spam\': 500}\n   >>> keys = dishes.keys()\n   >>> values = dishes.values()\n\n   >>> # iteration\n   >>> n = 0\n   >>> for val in values:\n   ...     n += val\n   >>> print(n)\n   504\n\n   >>> # keys and values are iterated over in the same order\n   >>> list(keys)\n   [\'eggs\', \'bacon\', \'sausage\', \'spam\']\n   >>> list(values)\n   [2, 1, 1, 500]\n\n   >>> # view objects are dynamic and reflect dict changes\n   >>> del dishes[\'eggs\']\n   >>> del dishes[\'sausage\']\n   >>> list(keys)\n   [\'spam\', \'bacon\']\n\n   >>> # set operations\n   >>> keys & {\'eggs\', \'bacon\', \'salad\'}\n   {\'bacon\'}\n   >>> keys ^ {\'sausage\', \'juice\'}\n   {\'juice\', \'eggs\', \'bacon\', \'spam\'}\n',
  'typesmethods': "\nMethods\n*******\n\nMethods are functions that are called using the attribute notation.\nThere are two flavors: built-in methods (such as ``append()`` on\nlists) and class instance methods.  Built-in methods are described\nwith the types that support them.\n\nIf you access a method (a function defined in a class namespace)\nthrough an instance, you get a special object: a *bound method* (also\ncalled *instance method*) object. When called, it will add the\n``self`` argument to the argument list.  Bound methods have two\nspecial read-only attributes: ``m.__self__`` is the object on which\nthe method operates, and ``m.__func__`` is the function implementing\nthe method.  Calling ``m(arg-1, arg-2, ..., arg-n)`` is completely\nequivalent to calling ``m.__func__(m.__self__, arg-1, arg-2, ...,\narg-n)``.\n\nLike function objects, bound method objects support getting arbitrary\nattributes.  However, since method attributes are actually stored on\nthe underlying function object (``meth.__func__``), setting method\nattributes on bound methods is disallowed.  Attempting to set a method\nattribute results in a ``TypeError`` being raised.  In order to set a\nmethod attribute, you need to explicitly set it on the underlying\nfunction object:\n\n   class C:\n       def method(self):\n           pass\n\n   c = C()\n   c.method.__func__.whoami = 'my name is c'\n\nSee *The standard type hierarchy* for more information.\n",
  'typesmodules': "\nModules\n*******\n\nThe only special operation on a module is attribute access:\n``m.name``, where *m* is a module and *name* accesses a name defined\nin *m*'s symbol table. Module attributes can be assigned to.  (Note\nthat the ``import`` statement is not, strictly speaking, an operation\non a module object; ``import foo`` does not require a module object\nnamed *foo* to exist, rather it requires an (external) *definition*\nfor a module named *foo* somewhere.)\n\nA special member of every module is ``__dict__``. This is the\ndictionary containing the module's symbol table. Modifying this\ndictionary will actually change the module's symbol table, but direct\nassignment to the ``__dict__`` attribute is not possible (you can\nwrite ``m.__dict__['a'] = 1``, which defines ``m.a`` to be ``1``, but\nyou can't write ``m.__dict__ = {}``).  Modifying ``__dict__`` directly\nis not recommended.\n\nModules built into the interpreter are written like this: ``<module\n'sys' (built-in)>``.  If loaded from a file, they are written as\n``<module 'os' from '/usr/local/lib/pythonX.Y/os.pyc'>``.\n",
- 'typesseq': '\nSequence Types --- ``str``, ``bytes``, ``bytearray``, ``list``, ``tuple``, ``range``\n************************************************************************************\n\nThere are six sequence types: strings, byte sequences (``bytes``\nobjects), byte arrays (``bytearray`` objects), lists, tuples, and\nrange objects.  For other containers see the built in ``dict`` and\n``set`` classes, and the ``collections`` module.\n\nStrings contain Unicode characters.  Their literals are written in\nsingle or double quotes: ``\'xyzzy\'``, ``"frobozz"``.  See *String and\nBytes literals* for more about string literals.  In addition to the\nfunctionality described here, there are also string-specific methods\ndescribed in the *String Methods* section.\n\nBytes and bytearray objects contain single bytes -- the former is\nimmutable while the latter is a mutable sequence.  Bytes objects can\nbe constructed the constructor, ``bytes()``, and from literals; use a\n``b`` prefix with normal string syntax: ``b\'xyzzy\'``.  To construct\nbyte arrays, use the ``bytearray()`` function.\n\nWarning: While string objects are sequences of characters (represented by\n  strings of length 1), bytes and bytearray objects are sequences of\n  *integers* (between 0 and 255), representing the ASCII value of\n  single bytes.  That means that for a bytes or bytearray object *b*,\n  ``b[0]`` will be an integer, while ``b[0:1]`` will be a bytes or\n  bytearray object of length 1.  The representation of bytes objects\n  uses the literal format (``b\'...\'``) since it is generally more\n  useful than e.g. ``bytes([50, 19, 100])``.  You can always convert a\n  bytes object into a list of integers using ``list(b)``.Also, while\n  in previous Python versions, byte strings and Unicode strings could\n  be exchanged for each other rather freely (barring encoding issues),\n  strings and bytes are now completely separate concepts.  There\'s no\n  implicit en-/decoding if you pass and object of the wrong type.  A\n  string always compares unequal to a bytes or bytearray object.\n\nLists are constructed with square brackets, separating items with\ncommas: ``[a, b, c]``.  Tuples are constructed by the comma operator\n(not within square brackets), with or without enclosing parentheses,\nbut an empty tuple must have the enclosing parentheses, such as ``a,\nb, c`` or ``()``.  A single item tuple must have a trailing comma,\nsuch as ``(d,)``.\n\nObjects of type range are created using the ``range()`` function.\nThey don\'t support slicing, concatenation or repetition, and using\n``in``, ``not in``, ``min()`` or ``max()`` on them is inefficient.\n\nMost sequence types support the following operations.  The ``in`` and\n``not in`` operations have the same priorities as the comparison\noperations.  The ``+`` and ``*`` operations have the same priority as\nthe corresponding numeric operations. [3] Additional methods are\nprovided for *Mutable Sequence Types*.\n\nThis table lists the sequence operations sorted in ascending priority\n(operations in the same box have the same priority).  In the table,\n*s* and *t* are sequences of the same type; *n*, *i* and *j* are\nintegers:\n\n+--------------------+----------------------------------+------------+\n| Operation          | Result                           | Notes      |\n+====================+==================================+============+\n| ``x in s``         | ``True`` if an item of *s* is    | (1)        |\n|                    | equal to *x*, else ``False``     |            |\n+--------------------+----------------------------------+------------+\n| ``x not in s``     | ``False`` if an item of *s* is   | (1)        |\n|                    | equal to *x*, else ``True``      |            |\n+--------------------+----------------------------------+------------+\n| ``s + t``          | the concatenation of *s* and *t* | (6)        |\n+--------------------+----------------------------------+------------+\n| ``s * n, n * s``   | *n* shallow copies of *s*        | (2)        |\n|                    | concatenated                     |            |\n+--------------------+----------------------------------+------------+\n| ``s[i]``           | *i*\'th item of *s*, origin 0     | (3)        |\n+--------------------+----------------------------------+------------+\n| ``s[i:j]``         | slice of *s* from *i* to *j*     | (3)(4)     |\n+--------------------+----------------------------------+------------+\n| ``s[i:j:k]``       | slice of *s* from *i* to *j*     | (3)(5)     |\n|                    | with step *k*                    |            |\n+--------------------+----------------------------------+------------+\n| ``len(s)``         | length of *s*                    |            |\n+--------------------+----------------------------------+------------+\n| ``min(s)``         | smallest item of *s*             |            |\n+--------------------+----------------------------------+------------+\n| ``max(s)``         | largest item of *s*              |            |\n+--------------------+----------------------------------+------------+\n\nSequence types also support comparisons.  In particular, tuples and\nlists are compared lexicographically by comparing corresponding\nelements.  This means that to compare equal, every element must\ncompare equal and the two sequences must be of the same type and have\nthe same length.  (For full details see *Comparisons* in the language\nreference.)\n\nNotes:\n\n1. When *s* is a string object, the ``in`` and ``not in`` operations\n   act like a substring test.\n\n2. Values of *n* less than ``0`` are treated as ``0`` (which yields an\n   empty sequence of the same type as *s*).  Note also that the copies\n   are shallow; nested structures are not copied.  This often haunts\n   new Python programmers; consider:\n\n   >>> lists = [[]] * 3\n   >>> lists\n   [[], [], []]\n   >>> lists[0].append(3)\n   >>> lists\n   [[3], [3], [3]]\n\n   What has happened is that ``[[]]`` is a one-element list containing\n   an empty list, so all three elements of ``[[]] * 3`` are (pointers\n   to) this single empty list.  Modifying any of the elements of\n   ``lists`` modifies this single list. You can create a list of\n   different lists this way:\n\n   >>> lists = [[] for i in range(3)]\n   >>> lists[0].append(3)\n   >>> lists[1].append(5)\n   >>> lists[2].append(7)\n   >>> lists\n   [[3], [5], [7]]\n\n3. If *i* or *j* is negative, the index is relative to the end of the\n   string: ``len(s) + i`` or ``len(s) + j`` is substituted.  But note\n   that ``-0`` is still ``0``.\n\n4. The slice of *s* from *i* to *j* is defined as the sequence of\n   items with index *k* such that ``i <= k < j``.  If *i* or *j* is\n   greater than ``len(s)``, use ``len(s)``.  If *i* is omitted or\n   ``None``, use ``0``.  If *j* is omitted or ``None``, use\n   ``len(s)``.  If *i* is greater than or equal to *j*, the slice is\n   empty.\n\n5. The slice of *s* from *i* to *j* with step *k* is defined as the\n   sequence of items with index  ``x = i + n*k`` such that ``0 <= n <\n   (j-i)/k``.  In other words, the indices are ``i``, ``i+k``,\n   ``i+2*k``, ``i+3*k`` and so on, stopping when *j* is reached (but\n   never including *j*).  If *i* or *j* is greater than ``len(s)``,\n   use ``len(s)``.  If *i* or *j* are omitted or ``None``, they become\n   "end" values (which end depends on the sign of *k*).  Note, *k*\n   cannot be zero. If *k* is ``None``, it is treated like ``1``.\n\n6. If *s* and *t* are both strings, some Python implementations such\n   as CPython can usually perform an in-place optimization for\n   assignments of the form ``s=s+t`` or ``s+=t``.  When applicable,\n   this optimization makes quadratic run-time much less likely.  This\n   optimization is both version and implementation dependent. For\n   performance sensitive code, it is preferable to use the\n   ``str.join()`` method which assures consistent linear concatenation\n   performance across versions and implementations.\n\n\nString Methods\n==============\n\nString objects support the methods listed below.  Note that none of\nthese methods take keyword arguments.\n\nIn addition, Python\'s strings support the sequence type methods\ndescribed in the *Sequence Types --- str, bytes, bytearray, list,\ntuple, range* section. To output formatted strings, see the *String\nFormatting* section. Also, see the ``re`` module for string functions\nbased on regular expressions.\n\nstr.capitalize()\n\n   Return a copy of the string with only its first character\n   capitalized.\n\nstr.center(width[, fillchar])\n\n   Return centered in a string of length *width*. Padding is done\n   using the specified *fillchar* (default is a space).\n\nstr.count(sub[, start[, end]])\n\n   Return the number of non-overlapping occurrences of substring *sub*\n   in the range [*start*, *end*].  Optional arguments *start* and\n   *end* are interpreted as in slice notation.\n\nstr.encode([encoding[, errors]])\n\n   Return an encoded version of the string as a bytes object.  Default\n   encoding is the current default string encoding.  *errors* may be\n   given to set a different error handling scheme.  The default for\n   *errors* is ``\'strict\'``, meaning that encoding errors raise a\n   ``UnicodeError``.  Other possible values are ``\'ignore\'``,\n   ``\'replace\'``, ``\'xmlcharrefreplace\'``, ``\'backslashreplace\'`` and\n   any other name registered via ``codecs.register_error()``, see\n   section *Codec Base Classes*. For a list of possible encodings, see\n   section *Standard Encodings*.\n\nstr.endswith(suffix[, start[, end]])\n\n   Return ``True`` if the string ends with the specified *suffix*,\n   otherwise return ``False``.  *suffix* can also be a tuple of\n   suffixes to look for.  With optional *start*, test beginning at\n   that position.  With optional *end*, stop comparing at that\n   position.\n\nstr.expandtabs([tabsize])\n\n   Return a copy of the string where all tab characters are replaced\n   by one or more spaces, depending on the current column and the\n   given tab size.  The column number is reset to zero after each\n   newline occurring in the string. If *tabsize* is not given, a tab\n   size of ``8`` characters is assumed.  This doesn\'t understand other\n   non-printing characters or escape sequences.\n\nstr.find(sub[, start[, end]])\n\n   Return the lowest index in the string where substring *sub* is\n   found, such that *sub* is contained in the range [*start*, *end*].\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` if *sub* is not found.\n\nstr.format(*args, **kwargs)\n\n   Perform a string formatting operation.  The *format_string*\n   argument can contain literal text or replacement fields delimited\n   by braces ``{}``.  Each replacement field contains either the\n   numeric index of a positional argument, or the name of a keyword\n   argument.  Returns a copy of *format_string* where each replacement\n   field is replaced with the string value of the corresponding\n   argument.\n\n   >>> "The sum of 1 + 2 is {0}".format(1+2)\n   \'The sum of 1 + 2 is 3\'\n\n   See *Format String Syntax* for a description of the various\n   formatting options that can be specified in format strings.\n\nstr.index(sub[, start[, end]])\n\n   Like ``find()``, but raise ``ValueError`` when the substring is not\n   found.\n\nstr.isalnum()\n\n   Return true if all characters in the string are alphanumeric and\n   there is at least one character, false otherwise.\n\nstr.isalpha()\n\n   Return true if all characters in the string are alphabetic and\n   there is at least one character, false otherwise.\n\nstr.isdecimal()\n\n   Return true if all characters in the string are decimal characters\n   and there is at least one character, false otherwise. Decimal\n   characters include digit characters, and all characters that that\n   can be used to form decimal-radix numbers, e.g. U+0660, ARABIC-\n   INDIC DIGIT ZERO.\n\nstr.isdigit()\n\n   Return true if all characters in the string are digits and there is\n   at least one character, false otherwise.\n\nstr.isidentifier()\n\n   Return true if the string is a valid identifier according to the\n   language definition, section *Identifiers and keywords*.\n\nstr.islower()\n\n   Return true if all cased characters in the string are lowercase and\n   there is at least one cased character, false otherwise.\n\nstr.isnumeric()\n\n   Return true if all characters in the string are numeric characters,\n   and there is at least one character, false otherwise. Numeric\n   characters include digit characters, and all characters that have\n   the Unicode numeric value property, e.g. U+2155, VULGAR FRACTION\n   ONE FIFTH.\n\nstr.isprintable()\n\n   Return true if all characters in the string are printable or the\n   string is empty, false otherwise.  Nonprintable characters are\n   those characters defined in the Unicode character database as\n   "Other" or "Separator", excepting the ASCII space (0x20) which is\n   considered printable.  (Note that printable characters in this\n   context are those which should not be escaped when ``repr()`` is\n   invoked on a string.  It has no bearing on the handling of strings\n   written to ``sys.stdout`` or ``sys.stderr``.)\n\nstr.isspace()\n\n   Return true if there are only whitespace characters in the string\n   and there is at least one character, false otherwise.\n\nstr.istitle()\n\n   Return true if the string is a titlecased string and there is at\n   least one character, for example uppercase characters may only\n   follow uncased characters and lowercase characters only cased ones.\n   Return false otherwise.\n\nstr.isupper()\n\n   Return true if all cased characters in the string are uppercase and\n   there is at least one cased character, false otherwise.\n\nstr.join(seq)\n\n   Return a string which is the concatenation of the strings in the\n   sequence *seq*.  A ``TypeError`` will be raised if there are any\n   non-string values in *seq*, including ``bytes`` objects.  The\n   separator between elements is the string providing this method.\n\nstr.ljust(width[, fillchar])\n\n   Return the string left justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space).  The original string is returned if *width* is less than\n   ``len(s)``.\n\nstr.lower()\n\n   Return a copy of the string converted to lowercase.\n\nstr.lstrip([chars])\n\n   Return a copy of the string with leading characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a prefix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.lstrip()\n   \'spacious   \'\n   >>> \'www.example.com\'.lstrip(\'cmowz.\')\n   \'example.com\'\n\nstatic str.maketrans(x[, y[, z]])\n\n   This static method returns a translation table usable for\n   ``str.translate()``.\n\n   If there is only one argument, it must be a dictionary mapping\n   Unicode ordinals (integers) or characters (strings of length 1) to\n   Unicode ordinals, strings (of arbitrary lengths) or None.\n   Character keys will then be converted to ordinals.\n\n   If there are two arguments, they must be strings of equal length,\n   and in the resulting dictionary, each character in x will be mapped\n   to the character at the same position in y.  If there is a third\n   argument, it must be a string, whose characters will be mapped to\n   None in the result.\n\nstr.partition(sep)\n\n   Split the string at the first occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing the string itself, followed by\n   two empty strings.\n\nstr.replace(old, new[, count])\n\n   Return a copy of the string with all occurrences of substring *old*\n   replaced by *new*.  If the optional argument *count* is given, only\n   the first *count* occurrences are replaced.\n\nstr.rfind(sub[, start[, end]])\n\n   Return the highest index in the string where substring *sub* is\n   found, such that *sub* is contained within s[start,end].  Optional\n   arguments *start* and *end* are interpreted as in slice notation.\n   Return ``-1`` on failure.\n\nstr.rindex(sub[, start[, end]])\n\n   Like ``rfind()`` but raises ``ValueError`` when the substring *sub*\n   is not found.\n\nstr.rjust(width[, fillchar])\n\n   Return the string right justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space). The original string is returned if *width* is less than\n   ``len(s)``.\n\nstr.rpartition(sep)\n\n   Split the string at the last occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing two empty strings, followed by\n   the string itself.\n\nstr.rsplit([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string. If *maxsplit* is given, at most *maxsplit* splits\n   are done, the *rightmost* ones.  If *sep* is not specified or\n   ``None``, any whitespace string is a separator.  Except for\n   splitting from the right, ``rsplit()`` behaves like ``split()``\n   which is described in detail below.\n\nstr.rstrip([chars])\n\n   Return a copy of the string with trailing characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a suffix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.rstrip()\n   \'   spacious\'\n   >>> \'mississippi\'.rstrip(\'ipz\')\n   \'mississ\'\n\nstr.split([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string.  If *maxsplit* is given, at most *maxsplit*\n   splits are done (thus, the list will have at most ``maxsplit+1``\n   elements).  If *maxsplit* is not specified, then there is no limit\n   on the number of splits (all possible splits are made).\n\n   If *sep* is given, consecutive delimiters are not grouped together\n   and are deemed to delimit empty strings (for example,\n   ``\'1,,2\'.split(\',\')`` returns ``[\'1\', \'\', \'2\']``).  The *sep*\n   argument may consist of multiple characters (for example,\n   ``\'1<>2<>3\'.split(\'<>\')`` returns ``[\'1\', \'2\', \'3\']``). Splitting\n   an empty string with a specified separator returns ``[\'\']``.\n\n   If *sep* is not specified or is ``None``, a different splitting\n   algorithm is applied: runs of consecutive whitespace are regarded\n   as a single separator, and the result will contain no empty strings\n   at the start or end if the string has leading or trailing\n   whitespace.  Consequently, splitting an empty string or a string\n   consisting of just whitespace with a ``None`` separator returns\n   ``[]``.\n\n   For example, ``\' 1  2   3  \'.split()`` returns ``[\'1\', \'2\', \'3\']``,\n   and ``\'  1  2   3  \'.split(None, 1)`` returns ``[\'1\', \'2   3  \']``.\n\nstr.splitlines([keepends])\n\n   Return a list of the lines in the string, breaking at line\n   boundaries.  Line breaks are not included in the resulting list\n   unless *keepends* is given and true.\n\nstr.startswith(prefix[, start[, end]])\n\n   Return ``True`` if string starts with the *prefix*, otherwise\n   return ``False``. *prefix* can also be a tuple of prefixes to look\n   for.  With optional *start*, test string beginning at that\n   position.  With optional *end*, stop comparing string at that\n   position.\n\nstr.strip([chars])\n\n   Return a copy of the string with the leading and trailing\n   characters removed. The *chars* argument is a string specifying the\n   set of characters to be removed. If omitted or ``None``, the\n   *chars* argument defaults to removing whitespace. The *chars*\n   argument is not a prefix or suffix; rather, all combinations of its\n   values are stripped:\n\n   >>> \'   spacious   \'.strip()\n   \'spacious\'\n   >>> \'www.example.com\'.strip(\'cmowz.\')\n   \'example\'\n\nstr.swapcase()\n\n   Return a copy of the string with uppercase characters converted to\n   lowercase and vice versa.\n\nstr.title()\n\n   Return a titlecased version of the string: words start with\n   uppercase characters, all remaining cased characters are lowercase.\n\nstr.translate(map)\n\n   Return a copy of the *s* where all characters have been mapped\n   through the *map* which must be a dictionary of Unicode ordinals\n   (integers) to Unicode ordinals, strings or ``None``.  Unmapped\n   characters are left untouched. Characters mapped to ``None`` are\n   deleted.\n\n   You can use ``str.maketrans()`` to create a translation map from\n   character-to-character mappings in different formats.\n\n   Note: An even more flexible approach is to create a custom character\n     mapping codec using the ``codecs`` module (see\n     ``encodings.cp1251`` for an example).\n\nstr.upper()\n\n   Return a copy of the string converted to uppercase.\n\nstr.zfill(width)\n\n   Return the numeric string left filled with zeros in a string of\n   length *width*.  A sign prefix is handled correctly.  The original\n   string is returned if *width* is less than ``len(s)``.\n\n\nOld String Formatting Operations\n================================\n\nNote: The formatting operations described here are obsolete and may go\n  away in future versions of Python.  Use the new *String Formatting*\n  in new code.\n\nString objects have one unique built-in operation: the ``%`` operator\n(modulo). This is also known as the string *formatting* or\n*interpolation* operator. Given ``format % values`` (where *format* is\na string), ``%`` conversion specifications in *format* are replaced\nwith zero or more elements of *values*. The effect is similar to the\nusing ``sprintf()`` in the C language.\n\nIf *format* requires a single argument, *values* may be a single non-\ntuple object. [4]  Otherwise, *values* must be a tuple with exactly\nthe number of items specified by the format string, or a single\nmapping object (for example, a dictionary).\n\nA conversion specifier contains two or more characters and has the\nfollowing components, which must occur in this order:\n\n1. The ``\'%\'`` character, which marks the start of the specifier.\n\n2. Mapping key (optional), consisting of a parenthesised sequence of\n   characters (for example, ``(somename)``).\n\n3. Conversion flags (optional), which affect the result of some\n   conversion types.\n\n4. Minimum field width (optional).  If specified as an ``\'*\'``\n   (asterisk), the actual width is read from the next element of the\n   tuple in *values*, and the object to convert comes after the\n   minimum field width and optional precision.\n\n5. Precision (optional), given as a ``\'.\'`` (dot) followed by the\n   precision.  If specified as ``\'*\'`` (an asterisk), the actual width\n   is read from the next element of the tuple in *values*, and the\n   value to convert comes after the precision.\n\n6. Length modifier (optional).\n\n7. Conversion type.\n\nWhen the right argument is a dictionary (or other mapping type), then\nthe formats in the string *must* include a parenthesised mapping key\ninto that dictionary inserted immediately after the ``\'%\'`` character.\nThe mapping key selects the value to be formatted from the mapping.\nFor example:\n\n>>> print(\'%(language)s has %(#)03d quote types.\' % \\\n...       {\'language\': "Python", "#": 2})\nPython has 002 quote types.\n\nIn this case no ``*`` specifiers may occur in a format (since they\nrequire a sequential parameter list).\n\nThe conversion flag characters are:\n\n+-----------+-----------------------------------------------------------------------+\n| Flag      | Meaning                                                               |\n+===========+=======================================================================+\n| ``\'#\'``   | The value conversion will use the "alternate form" (where defined     |\n|           | below).                                                               |\n+-----------+-----------------------------------------------------------------------+\n| ``\'0\'``   | The conversion will be zero padded for numeric values.                |\n+-----------+-----------------------------------------------------------------------+\n| ``\'-\'``   | The converted value is left adjusted (overrides the ``\'0\'``           |\n|           | conversion if both are given).                                        |\n+-----------+-----------------------------------------------------------------------+\n| ``\' \'``   | (a space) A blank should be left before a positive number (or empty   |\n|           | string) produced by a signed conversion.                              |\n+-----------+-----------------------------------------------------------------------+\n| ``\'+\'``   | A sign character (``\'+\'`` or ``\'-\'``) will precede the conversion     |\n|           | (overrides a "space" flag).                                           |\n+-----------+-----------------------------------------------------------------------+\n\nA length modifier (``h``, ``l``, or ``L``) may be present, but is\nignored as it is not necessary for Python -- so e.g. ``%ld`` is\nidentical to ``%d``.\n\nThe conversion types are:\n\n+--------------+-------------------------------------------------------+---------+\n| Conversion   | Meaning                                               | Notes   |\n+==============+=======================================================+=========+\n| ``\'d\'``      | Signed integer decimal.                               |         |\n+--------------+-------------------------------------------------------+---------+\n| ``\'i\'``      | Signed integer decimal.                               |         |\n+--------------+-------------------------------------------------------+---------+\n| ``\'o\'``      | Signed octal value.                                   | (1)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'u\'``      | Obsolete type -- it is identical to ``\'d\'``.          | (7)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'x\'``      | Signed hexadecimal (lowercase).                       | (2)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'X\'``      | Signed hexadecimal (uppercase).                       | (2)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'e\'``      | Floating point exponential format (lowercase).        | (3)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'E\'``      | Floating point exponential format (uppercase).        | (3)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'f\'``      | Floating point decimal format.                        | (3)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'F\'``      | Floating point decimal format.                        | (3)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'g\'``      | Floating point format.

The alternate form causes a leading zero (``\'0\'``) to be inserted\n   between left-hand padding and the formatting of the number if the\n   leading character of the result is not already a zero.\n\n2. The alternate form causes a leading ``\'0x\'`` or ``\'0X\'`` (depending\n   on whether the ``\'x\'`` or ``\'X\'`` format was used) to be inserted\n   between left-hand padding and the formatting of the number if the\n   leading character of the result is not already a zero.\n\n3. The alternate form causes the result to always contain a decimal\n   point, even if no digits follow it.\n\n   The precision determines the number of digits after the decimal\n   point and defaults to 6.\n\n4. The alternate form causes the result to always contain a decimal\n   point, and trailing zeroes are not removed as they would otherwise\n   be.\n\n   The precision determines the number of significant digits before\n   and after the decimal point and defaults to 6.\n\n5. The precision determines the maximal number of characters used.\n\n1. See **PEP 237**.\n\nSince Python strings have an explicit length, ``%s`` conversions do\nnot assume that ``\'\\0\'`` is the end of the string.\n\nChanged in version 3.1: ``%f`` conversions for numbers whose absolute\nvalue is over 1e50 are no longer replaced by ``%g`` conversions.\n\nAdditional string operations are defined in standard modules\n``string`` and ``re``.\n\n\nRange Type\n==========\n\nThe ``range`` type is an immutable sequence which is commonly used for\nlooping.  The advantage of the ``range`` type is that an ``range``\nobject will always take the same amount of memory, no matter the size\nof the range it represents.  There are no consistent performance\nadvantages.\n\nRange objects have very little behavior: they only support indexing,\niteration, and the ``len()`` function.\n\n\nMutable Sequence Types\n======================\n\nList and bytearray objects support additional operations that allow\nin-place modification of the object.  Other mutable sequence types\n(when added to the language) should also support these operations.\nStrings and tuples are immutable sequence types: such objects cannot\nbe modified once created. The following operations are defined on\nmutable sequence types (where *x* is an arbitrary object).\n\nNote that while lists allow their items to be of any type, bytearray\nobject "items" are all integers in the range 0 <= x < 256.\n\n+--------------------------------+----------------------------------+-----------------------+\n| Operation                      | Result                           | Notes                 |\n+================================+==================================+=======================+\n| ``s[i] = x``                   | item *i* of *s* is replaced by   |                       |\n|                                | *x*                              |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s[i:j] = t``                 | slice of *s* from *i* to *j* is  |                       |\n|                                | replaced by the contents of the  |                       |\n|                                | iterable *t*                     |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``del s[i:j]``                 | same as ``s[i:j] = []``          |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s[i:j:k] = t``               | the elements of ``s[i:j:k]`` are | (1)                   |\n|                                | replaced by those of *t*         |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``del s[i:j:k]``               | removes the elements of          |                       |\n|                                | ``s[i:j:k]`` from the list       |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.append(x)``                | same as ``s[len(s):len(s)] =     |                       |\n|                                | [x]``                            |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.extend(x)``                | same as ``s[len(s):len(s)] = x`` | (2)                   |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.count(x)``                 | return number of *i*\'s for which |                       |\n|                                | ``s[i] == x``                    |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.index(x[, i[, j]])``       | return smallest *k* such that    | (3)                   |\n|                                | ``s[k] == x`` and ``i <= k < j`` |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.insert(i, x)``             | same as ``s[i:i] = [x]``         | (4)                   |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.pop([i])``                 | same as ``x = s[i]; del s[i];    | (5)                   |\n|                                | return x``                       |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.remove(x)``                | same as ``del s[s.index(x)]``    | (3)                   |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.reverse()``                | reverses the items of *s* in     | (6)                   |\n|                                | place                            |                       |\n+--------------------------------+----------------------------------+-----------------------+\n| ``s.sort([key[, reverse]])``   | sort the items of *s* in place   | (6), (7), (8)         |\n+--------------------------------+----------------------------------+-----------------------+\n\nNotes:\n\n1. *t* must have the same length as the slice it is replacing.\n\n2. *x* can be any iterable object.\n\n3. Raises ``ValueError`` when *x* is not found in *s*. When a negative\n   index is passed as the second or third parameter to the ``index()``\n   method, the sequence length is added, as for slice indices.  If it\n   is still negative, it is truncated to zero, as for slice indices.\n\n4. When a negative index is passed as the first parameter to the\n   ``insert()`` method, the sequence length is added, as for slice\n   indices.  If it is still negative, it is truncated to zero, as for\n   slice indices.\n\n5. The optional argument *i* defaults to ``-1``, so that by default\n   the last item is removed and returned.\n\n6. The ``sort()`` and ``reverse()`` methods modify the sequence in\n   place for economy of space when sorting or reversing a large\n   sequence.  To remind you that they operate by side effect, they\n   don\'t return the sorted or reversed sequence.\n\n7. The ``sort()`` method takes optional arguments for controlling the\n   comparisons.  Each must be specified as a keyword argument.\n\n   *key* specifies a function of one argument that is used to extract\n   a comparison key from each list element: ``key=str.lower``.  The\n   default value is ``None``.\n\n   *reverse* is a boolean value.  If set to ``True``, then the list\n   elements are sorted as if each comparison were reversed.\n\n   The ``sort()`` method is guaranteed to be stable.

The C implementation makes\n   the list appear empty for the duration, and raises ``ValueError``\n   if it can detect that the list has been mutated during a sort.\n\n8. ``sort()`` is not supported by ``bytearray`` objects.\n\n\nBytes and Byte Array Methods\n============================\n\nBytes and bytearray objects, being "strings of bytes", have all\nmethods found on strings, with the exception of ``encode()``,\n``format()`` and ``isidentifier()``, which do not make sense with\nthese types.  For converting the objects to strings, they have a\n``decode()`` method.\n\nWherever one of these methods needs to interpret the bytes as\ncharacters (e.g. the ``is...()`` methods), the ASCII character set is\nassumed.\n\nNote: The methods on bytes and bytearray objects don\'t accept strings as\n  their arguments, just as the methods on strings don\'t accept bytes\n  as their arguments.  For example, you have to write\n\n     a = "abc"\n     b = a.replace("a", "f")\n\n  and\n\n     a = b"abc"\n     b = a.replace(b"a", b"f")\n\nbytes.decode([encoding[, errors]])\nbytearray.decode([encoding[, errors]])\n\n   Return a string decoded from the given bytes.  Default encoding is\n   the current default string encoding.  *errors* may be given to set\n   a different error handling scheme.  The default for *errors* is\n   ``\'strict\'``, meaning that encoding errors raise a\n   ``UnicodeError``.  Other possible values are ``\'ignore\'``,\n   ``\'replace\'`` and any other name registered via\n   ``codecs.register_error()``, see section *Codec Base Classes*. For\n   a list of possible encodings, see section *Standard Encodings*.\n\nThe bytes and bytearray types have an additional class method:\n\nclassmethod bytes.fromhex(string)\nclassmethod bytearray.fromhex(string)\n\n   This ``bytes`` class method returns a bytes or bytearray object,\n   decoding the given string object.  The string must contain two\n   hexadecimal digits per byte, spaces are ignored.\n\n   >>> bytes.fromhex(\'f0 f1f2  \')\n   b\'\\xf0\\xf1\\xf2\'\n\nThe maketrans and translate methods differ in semantics from the\nversions available on strings:\n\nbytes.translate(table[, delete])\nbytearray.translate(table[, delete])\n\n   Return a copy of the bytes or bytearray object where all bytes\n   occurring in the optional argument *delete* are removed, and the\n   remaining bytes have been mapped through the given translation\n   table, which must be a bytes object of length 256.\n\n   You can use the ``bytes.maketrans()`` method to create a\n   translation table.\n\n   Set the *table* argument to ``None`` for translations that only\n   delete characters:\n\n      >>> b\'read this short text\'.translate(None, b\'aeiou\')\n      b\'rd ths shrt txt\'\n\nstatic bytes.maketrans(from, to)\nstatic bytearray.maketrans(from, to)\n\n   This static method returns a translation table usable for\n   ``bytes.translate()`` that will map each character in *from* into\n   the character at the same position in *to*; *from* and *to* must be\n   bytes objects and have the same length.\n\n   New in version 3.1.\n',

+ 'typesseq': '\nSequence Types --- ``str``, ``bytes``, ``bytearray``, ``list``, ``tuple``, ``range``\n************************************************************************************\n\nThere are six sequence types: strings, byte sequences (``bytes``\nobjects), byte arrays (``bytearray`` objects), lists, tuples, and\nrange objects.  For other containers see the built in ``dict`` and\n``set`` classes, and the ``collections`` module.\n\nStrings contain Unicode characters.  Their literals are written in\nsingle or double quotes: ``\'xyzzy\'``, ``"frobozz"``.  See *String and\nBytes literals* for more about string literals.  In addition to the\nfunctionality described here, there are also string-specific methods\ndescribed in the *String Methods* section.\n\nBytes and bytearray objects contain single bytes -- the former is\nimmutable while the latter is a mutable sequence.  Bytes objects can\nbe constructed the constructor, ``bytes()``, and from literals; use a\n``b`` prefix with normal string syntax: ``b\'xyzzy\'``.  To construct\nbyte arrays, use the ``bytearray()`` function.\n\nWhile string objects are sequences of characters (represented by\nstrings of length 1), bytes and bytearray objects are sequences of\n*integers* (between 0 and 255), representing the ASCII value of single\nbytes.  That means that for a bytes or bytearray object *b*, ``b[0]``\nwill be an integer, while ``b[0:1]`` will be a bytes or bytearray\nobject of length 1.  The representation of bytes objects uses the\nliteral format (``b\'...\'``) since it is generally more useful than\ne.g. ``bytes([50, 19, 100])``.  You can always convert a bytes object\ninto a list of integers using ``list(b)``.\n\nAlso, while in previous Python versions, byte strings and Unicode\nstrings could be exchanged for each other rather freely (barring\nencoding issues), strings and bytes are now completely separate\nconcepts.  There\'s no implicit en-/decoding if you pass an object of\nthe wrong type.  A string always compares unequal to a bytes or\nbytearray object.\n\nLists are constructed with square brackets, separating items with\ncommas: ``[a, b, c]``.  Tuples are constructed by the comma operator\n(not within square brackets), with or without enclosing parentheses,\nbut an empty tuple must have the enclosing parentheses, such as ``a,\nb, c`` or ``()``.  A single item tuple must have a trailing comma,\nsuch as ``(d,)``.\n\nObjects of type range are created using the ``range()`` function.\nThey don\'t support concatenation or repetition, and using ``min()`` or\n``max()`` on them is inefficient.\n\nMost sequence types support the following operations.  The ``in`` and\n``not in`` operations have the same priorities as the comparison\noperations.  The ``+`` and ``*`` operations have the same priority as\nthe corresponding numeric operations. [3] Additional methods are\nprovided for *Mutable Sequence Types*.\n\nThis table lists the sequence operations sorted in ascending priority\n(operations in the same box have the same priority).  In the table,\n*s* and *t* are sequences of the same type; *n*, *i*, *j* and *k* are\nintegers.\n\n+--------------------+----------------------------------+------------+\n| Operation          | Result                           | Notes      |\n+====================+==================================+============+\n| ``x in s``         | ``True`` if an item of *s* is    | (1)        |\n|                    | equal to *x*, else ``False``     |            |\n+--------------------+----------------------------------+------------+\n| ``x not in s``     | ``False`` if an item of *s* is   | (1)        |\n|                    | equal to *x*, else ``True``      |            |\n+--------------------+----------------------------------+------------+\n| ``s + t``          | the concatenation of *s* and *t* | (6)        |\n+--------------------+----------------------------------+------------+\n| ``s * n, n * s``   | *n* shallow copies of *s*        | (2)        |\n|                    | concatenated                     |            |\n+--------------------+----------------------------------+------------+\n| ``s[i]``           | *i*\'th item of *s*, origin 0     | (3)        |\n+--------------------+----------------------------------+------------+\n| ``s[i:j]``         | slice of *s* from *i* to *j*     | (3)(4)     |\n+--------------------+----------------------------------+------------+\n| ``s[i:j:k]``       | slice of *s* from *i* to *j*     | (3)(5)     |\n|                    | with step *k*                    |            |\n+--------------------+----------------------------------+------------+\n| ``len(s)``         | length of *s*                    |            |\n+--------------------+----------------------------------+------------+\n| ``min(s)``         | smallest item of *s*             |            |\n+--------------------+----------------------------------+------------+\n| ``max(s)``         | largest item of *s*              |            |\n+--------------------+----------------------------------+------------+\n| ``s.index(i)``     | index of the first occurence of  |            |\n|                    | *i* in *s*                       |            |\n+--------------------+----------------------------------+------------+\n| ``s.count(i)``     | total number of occurences of    |            |\n|                    | *i* in *s*                       |            |\n+--------------------+----------------------------------+------------+\n\nSequence types also support comparisons.  In particular, tuples and\nlists are compared lexicographically by comparing corresponding\nelements.  This means that to compare equal, every element must\ncompare equal and the two sequences must be of the same type and have\nthe same length.  (For full details see *Comparisons* in the language\nreference.)\n\nNotes:\n\n1. When *s* is a string object, the ``in`` and ``not in`` operations\n   act like a substring test.\n\n2. Values of *n* less than ``0`` are treated as ``0`` (which yields an\n   empty sequence of the same type as *s*).  Note also that the copies\n   are shallow; nested structures are not copied.  This often haunts\n   new Python programmers; consider:\n\n   >>> lists = [[]] * 3\n   >>> lists\n   [[], [], []]\n   >>> lists[0].append(3)\n   >>> lists\n   [[3], [3], [3]]\n\n   What has happened is that ``[[]]`` is a one-element list containing\n   an empty list, so all three elements of ``[[]] * 3`` are (pointers\n   to) this single empty list.  Modifying any of the elements of\n   ``lists`` modifies this single list. You can create a list of\n   different lists this way:\n\n   >>> lists = [[] for i in range(3)]\n   >>> lists[0].append(3)\n   >>> lists[1].append(5)\n   >>> lists[2].append(7)\n   >>> lists\n   [[3], [5], [7]]\n\n3. If *i* or *j* is negative, the index is relative to the end of the\n   string: ``len(s) + i`` or ``len(s) + j`` is substituted.  But note\n   that ``-0`` is still ``0``.\n\n4. The slice of *s* from *i* to *j* is defined as the sequence of\n   items with index *k* such that ``i <= k < j``.  If *i* or *j* is\n   greater than ``len(s)``, use ``len(s)``.  If *i* is omitted or\n   ``None``, use ``0``.  If *j* is omitted or ``None``, use\n   ``len(s)``.  If *i* is greater than or equal to *j*, the slice is\n   empty.\n\n5. The slice of *s* from *i* to *j* with step *k* is defined as the\n   sequence of items with index  ``x = i + n*k`` such that ``0 <= n <\n   (j-i)/k``.  In other words, the indices are ``i``, ``i+k``,\n   ``i+2*k``, ``i+3*k`` and so on, stopping when *j* is reached (but\n   never including *j*).  If *i* or *j* is greater than ``len(s)``,\n   use ``len(s)``.  If *i* or *j* are omitted or ``None``, they become\n   "end" values (which end depends on the sign of *k*).  Note, *k*\n   cannot be zero. If *k* is ``None``, it is treated like ``1``.\n\n6. **CPython implementation detail:** If *s* and *t* are both strings,\n   some Python implementations such as CPython can usually perform an\n   in-place optimization for assignments of the form ``s = s + t`` or\n   ``s += t``.  When applicable, this optimization makes quadratic\n   run-time much less likely.  This optimization is both version and\n   implementation dependent.  For performance sensitive code, it is\n   preferable to use the ``str.join()`` method which assures\n   consistent linear concatenation performance across versions and\n   implementations.\n\n\nString Methods\n==============\n\nString objects support the methods listed below.\n\nIn addition, Python\'s strings support the sequence type methods\ndescribed in the *Sequence Types --- str, bytes, bytearray, list,\ntuple, range* section. To output formatted strings, see the *String\nFormatting* section. Also, see the ``re`` module for string functions\nbased on regular expressions.\n\nstr.capitalize()\n\n   Return a copy of the string with its first character capitalized\n   and the rest lowercased.\n\nstr.center(width[, fillchar])\n\n   Return centered in a string of length *width*. Padding is done\n   using the specified *fillchar* (default is a space).\n\nstr.count(sub[, start[, end]])\n\n   Return the number of non-overlapping occurrences of substring *sub*\n   in the range [*start*, *end*].  Optional arguments *start* and\n   *end* are interpreted as in slice notation.\n\nstr.encode(encoding="utf-8", errors="strict")\n\n   Return an encoded version of the string as a bytes object. Default\n   encoding is ``\'utf-8\'``. *errors* may be given to set a different\n   error handling scheme. The default for *errors* is ``\'strict\'``,\n   meaning that encoding errors raise a ``UnicodeError``. Other\n   possible values are ``\'ignore\'``, ``\'replace\'``,\n   ``\'xmlcharrefreplace\'``, ``\'backslashreplace\'`` and any other name\n   registered via ``codecs.register_error()``, see section *Codec Base\n   Classes*. For a list of possible encodings, see section *Standard\n   Encodings*.\n\n   Changed in version 3.1: Support for keyword arguments added.\n\nstr.endswith(suffix[, start[, end]])\n\n   Return ``True`` if the string ends with the specified *suffix*,\n   otherwise return ``False``.  *suffix* can also be a tuple of\n   suffixes to look for.  With optional *start*, test beginning at\n   that position.  With optional *end*, stop comparing at that\n   position.\n\nstr.expandtabs([tabsize])\n\n   Return a copy of the string where all tab characters are replaced\n   by one or more spaces, depending on the current column and the\n   given tab size.  The column number is reset to zero after each\n   newline occurring in the string. If *tabsize* is not given, a tab\n   size of ``8`` characters is assumed.  This doesn\'t understand other\n   non-printing characters or escape sequences.\n\nstr.find(sub[, start[, end]])\n\n   Return the lowest index in the string where substring *sub* is\n   found, such that *sub* is contained in the slice ``s[start:end]``.\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` if *sub* is not found.\n\nstr.format(*args, **kwargs)\n\n   Perform a string formatting operation.  The string on which this\n   method is called can contain literal text or replacement fields\n   delimited by braces ``{}``.  Each replacement field contains either\n   the numeric index of a positional argument, or the name of a\n   keyword argument.  Returns a copy of the string where each\n   replacement field is replaced with the string value of the\n   corresponding argument.\n\n   >>> "The sum of 1 + 2 is {0}".format(1+2)\n   \'The sum of 1 + 2 is 3\'\n\n   See *Format String Syntax* for a description of the various\n   formatting options that can be specified in format strings.\n\nstr.format_map(mapping)\n\n   Similar to ``str.format(**mapping)``, except that ``mapping`` is\n   used directly and not copied to a ``dict`` .  This is useful if for\n   example ``mapping`` is a dict subclass:\n\n   >>> class Default(dict):\n   ...     def __missing__(self, key):\n   ...         return key\n   ...\n   >>> \'{name} was born in {country}\'.format_map(Default(name=\'Guido\'))\n   \'Guido was born in country\'\n\n   New in version 3.2.\n\nstr.index(sub[, start[, end]])\n\n   Like ``find()``, but raise ``ValueError`` when the substring is not\n   found.\n\nstr.isalnum()\n\n   Return true if all characters in the string are alphanumeric and\n   there is at least one character, false otherwise.  A character\n   ``c`` is alphanumeric if one of the following returns ``True``:\n   ``c.isalpha()``, ``c.isdecimal()``, ``c.isdigit()``, or\n   ``c.isnumeric()``.\n\nstr.isalpha()\n\n   Return true if all characters in the string are alphabetic and\n   there is at least one character, false otherwise.  Alphabetic\n   characters are those characters defined in the Unicode character\n   database as "Letter", i.e., those with general category property\n   being one of "Lm", "Lt", "Lu", "Ll", or "Lo".  Note that this is\n   different from the "Alphabetic" property defined in the Unicode\n   Standard.\n\nstr.isdecimal()\n\n   Return true if all characters in the string are decimal characters\n   and there is at least one character, false otherwise. Decimal\n   characters are those from general category "Nd". This category\n   includes digit characters, and all characters that that can be used\n   to form decimal-radix numbers, e.g. U+0660, ARABIC-INDIC DIGIT\n   ZERO.\n\nstr.isdigit()\n\n   Return true if all characters in the string are digits and there is\n   at least one character, false otherwise.  Digits include decimal\n   characters and digits that need special handling, such as the\n   compatibility superscript digits.  Formally, a digit is a character\n   that has the property value Numeric_Type=Digit or\n   Numeric_Type=Decimal.\n\nstr.isidentifier()\n\n   Return true if the string is a valid identifier according to the\n   language definition, section *Identifiers and keywords*.\n\nstr.islower()\n\n   Return true if all cased characters in the string are lowercase and\n   there is at least one cased character, false otherwise.  Cased\n   characters are those with general category property being one of\n   "Lu", "Ll", or "Lt" and lowercase characters are those with general\n   category property "Ll".\n\nstr.isnumeric()\n\n   Return true if all characters in the string are numeric characters,\n   and there is at least one character, false otherwise. Numeric\n   characters include digit characters, and all characters that have\n   the Unicode numeric value property, e.g. U+2155, VULGAR FRACTION\n   ONE FIFTH.  Formally, numeric characters are those with the\n   property value Numeric_Type=Digit, Numeric_Type=Decimal or\n   Numeric_Type=Numeric.\n\nstr.isprintable()\n\n   Return true if all characters in the string are printable or the\n   string is empty, false otherwise.  Nonprintable characters are\n   those characters defined in the Unicode character database as\n   "Other" or "Separator", excepting the ASCII space (0x20) which is\n   considered printable.  (Note that printable characters in this\n   context are those which should not be escaped when ``repr()`` is\n   invoked on a string.  It has no bearing on the handling of strings\n   written to ``sys.stdout`` or ``sys.stderr``.)\n\nstr.isspace()\n\n   Return true if there are only whitespace characters in the string\n   and there is at least one character, false otherwise.  Whitespace\n   characters  are those characters defined in the Unicode character\n   database as "Other" or "Separator" and those with bidirectional\n   property being one of "WS", "B", or "S".\n\nstr.istitle()\n\n   Return true if the string is a titlecased string and there is at\n   least one character, for example uppercase characters may only\n   follow uncased characters and lowercase characters only cased ones.\n   Return false otherwise.\n\nstr.isupper()\n\n   Return true if all cased characters in the string are uppercase and\n   there is at least one cased character, false otherwise. Cased\n   characters are those with general category property being one of\n   "Lu", "Ll", or "Lt" and uppercase characters are those with general\n   category property "Lu".\n\nstr.join(iterable)\n\n   Return a string which is the concatenation of the strings in the\n   *iterable* *iterable*.  A ``TypeError`` will be raised if there are\n   any non-string values in *seq*, including ``bytes`` objects.  The\n   separator between elements is the string providing this method.\n\nstr.ljust(width[, fillchar])\n\n   Return the string left justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space).  The original string is returned if *width* is less than\n   ``len(s)``.\n\nstr.lower()\n\n   Return a copy of the string converted to lowercase.\n\nstr.lstrip([chars])\n\n   Return a copy of the string with leading characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a prefix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.lstrip()\n   \'spacious   \'\n   >>> \'www.example.com\'.lstrip(\'cmowz.\')\n   \'example.com\'\n\nstatic str.maketrans(x[, y[, z]])\n\n   This static method returns a translation table usable for\n   ``str.translate()``.\n\n   If there is only one argument, it must be a dictionary mapping\n   Unicode ordinals (integers) or characters (strings of length 1) to\n   Unicode ordinals, strings (of arbitrary lengths) or None.\n   Character keys will then be converted to ordinals.\n\n   If there are two arguments, they must be strings of equal length,\n   and in the resulting dictionary, each character in x will be mapped\n   to the character at the same position in y.  If there is a third\n   argument, it must be a string, whose characters will be mapped to\n   None in the result.\n\nstr.partition(sep)\n\n   Split the string at the first occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing the string itself, followed by\n   two empty strings.\n\nstr.replace(old, new[, count])\n\n   Return a copy of the string with all occurrences of substring *old*\n   replaced by *new*.  If the optional argument *count* is given, only\n   the first *count* occurrences are replaced.\n\nstr.rfind(sub[, start[, end]])\n\n   Return the highest index in the string where substring *sub* is\n   found, such that *sub* is contained within ``s[start:end]``.\n   Optional arguments *start* and *end* are interpreted as in slice\n   notation.  Return ``-1`` on failure.\n\nstr.rindex(sub[, start[, end]])\n\n   Like ``rfind()`` but raises ``ValueError`` when the substring *sub*\n   is not found.\n\nstr.rjust(width[, fillchar])\n\n   Return the string right justified in a string of length *width*.\n   Padding is done using the specified *fillchar* (default is a\n   space). The original string is returned if *width* is less than\n   ``len(s)``.\n\nstr.rpartition(sep)\n\n   Split the string at the last occurrence of *sep*, and return a\n   3-tuple containing the part before the separator, the separator\n   itself, and the part after the separator.  If the separator is not\n   found, return a 3-tuple containing two empty strings, followed by\n   the string itself.\n\nstr.rsplit([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string. If *maxsplit* is given, at most *maxsplit* splits\n   are done, the *rightmost* ones.  If *sep* is not specified or\n   ``None``, any whitespace string is a separator.  Except for\n   splitting from the right, ``rsplit()`` behaves like ``split()``\n   which is described in detail below.\n\nstr.rstrip([chars])\n\n   Return a copy of the string with trailing characters removed.  The\n   *chars* argument is a string specifying the set of characters to be\n   removed.  If omitted or ``None``, the *chars* argument defaults to\n   removing whitespace.  The *chars* argument is not a suffix; rather,\n   all combinations of its values are stripped:\n\n   >>> \'   spacious   \'.rstrip()\n   \'   spacious\'\n   >>> \'mississippi\'.rstrip(\'ipz\')\n   \'mississ\'\n\nstr.split([sep[, maxsplit]])\n\n   Return a list of the words in the string, using *sep* as the\n   delimiter string.  If *maxsplit* is given, at most *maxsplit*\n   splits are done (thus, the list will have at most ``maxsplit+1``\n   elements).  If *maxsplit* is not specified, then there is no limit\n   on the number of splits (all possible splits are made).\n\n   If *sep* is given, consecutive delimiters are not grouped together\n   and are deemed to delimit empty strings (for example,\n   ``\'1,,2\'.split(\',\')`` returns ``[\'1\', \'\', \'2\']``).  The *sep*\n   argument may consist of multiple characters (for example,\n   ``\'1<>2<>3\'.split(\'<>\')`` returns ``[\'1\', \'2\', \'3\']``). Splitting\n   an empty string with a specified separator returns ``[\'\']``.\n\n   If *sep* is not specified or is ``None``, a different splitting\n   algorithm is applied: runs of consecutive whitespace are regarded\n   as a single separator, and the result will contain no empty strings\n   at the start or end if the string has leading or trailing\n   whitespace.  Consequently, splitting an empty string or a string\n   consisting of just whitespace with a ``None`` separator returns\n   ``[]``.\n\n   For example, ``\' 1  2   3  \'.split()`` returns ``[\'1\', \'2\', \'3\']``,\n   and ``\'  1  2   3  \'.split(None, 1)`` returns ``[\'1\', \'2   3  \']``.\n\nstr.splitlines([keepends])\n\n   Return a list of the lines in the string, breaking at line\n   boundaries.  Line breaks are not included in the resulting list\n   unless *keepends* is given and true.\n\nstr.startswith(prefix[, start[, end]])\n\n   Return ``True`` if string starts with the *prefix*, otherwise\n   return ``False``. *prefix* can also be a tuple of prefixes to look\n   for.  With optional *start*, test string beginning at that\n   position.  With optional *end*, stop comparing string at that\n   position.\n\nstr.strip([chars])\n\n   Return a copy of the string with the leading and trailing\n   characters removed. The *chars* argument is a string specifying the\n   set of characters to be removed. If omitted or ``None``, the\n   *chars* argument defaults to removing whitespace. The *chars*\n   argument is not a prefix or suffix; rather, all combinations of its\n   values are stripped:\n\n   >>> \'   spacious   \'.strip()\n   \'spacious\'\n   >>> \'www.example.com\'.strip(\'cmowz.\')\n   \'example\'\n\nstr.swapcase()\n\n   Return a copy of the string with uppercase characters converted to\n   lowercase and vice versa.\n\nstr.title()\n\n   Return a titlecased version of the string where words start with an\n   uppercase character and the remaining characters are lowercase.\n\n   The algorithm uses a simple language-independent definition of a\n   word as groups of consecutive letters.  The definition works in\n   many contexts but it means that apostrophes in contractions and\n   possessives form word boundaries, which may not be the desired\n   result:\n\n      >>> "they\'re bill\'s friends from the UK".title()\n      "They\'Re Bill\'S Friends From The Uk"\n\n   A workaround for apostrophes can be constructed using regular\n   expressions:\n\n      >>> import re\n      >>> def titlecase(s):\n              return re.sub(r"[A-Za-z]+(\'[A-Za-z]+)?",\n                            lambda mo: mo.group(0)[0].upper() +\n                                       mo.group(0)[1:].lower(),\n                            s)\n\n      >>> titlecase("they\'re bill\'s friends.")\n      "They\'re Bill\'s Friends."\n\nstr.translate(map)\n\n   Return a copy of the *s* where all characters have been mapped\n   through the *map* which must be a dictionary of Unicode ordinals\n   (integers) to Unicode ordinals, strings or ``None``.  Unmapped\n   characters are left untouched. Characters mapped to ``None`` are\n   deleted.\n\n   You can use ``str.maketrans()`` to create a translation map from\n   character-to-character mappings in different formats.\n\n   Note: An even more flexible approach is to create a custom character\n     mapping codec using the ``codecs`` module (see\n     ``encodings.cp1251`` for an example).\n\nstr.upper()\n\n   Return a copy of the string converted to uppercase.\n\nstr.zfill(width)\n\n   Return the numeric string left filled with zeros in a string of\n   length *width*.  A sign prefix is handled correctly.  The original\n   string is returned if *width* is less than ``len(s)``.\n\n\nOld String Formatting Operations\n================================\n\nNote: The formatting operations described here are obsolete and may go\n  away in future versions of Python.  Use the new *String Formatting*\n  in new code.\n\nString objects have one unique built-in operation: the ``%`` operator\n(modulo). This is also known as the string *formatting* or\n*interpolation* operator. Given ``format % values`` (where *format* is\na string), ``%`` conversion specifications in *format* are replaced\nwith zero or more elements of *values*. The effect is similar to the\nusing ``sprintf()`` in the C language.\n\nIf *format* requires a single argument, *values* may be a single non-\ntuple object. [4]  Otherwise, *values* must be a tuple with exactly\nthe number of items specified by the format string, or a single\nmapping object (for example, a dictionary).\n\nA conversion specifier contains two or more characters and has the\nfollowing components, which must occur in this order:\n\n1. The ``\'%\'`` character, which marks the start of the specifier.\n\n2. Mapping key (optional), consisting of a parenthesised sequence of\n   characters (for example, ``(somename)``).\n\n3. Conversion flags (optional), which affect the result of some\n   conversion types.\n\n4. Minimum field width (optional).  If specified as an ``\'*\'``\n   (asterisk), the actual width is read from the next element of the\n   tuple in *values*, and the object to convert comes after the\n   minimum field width and optional precision.\n\n5. Precision (optional), given as a ``\'.\'`` (dot) followed by the\n   precision.  If specified as ``\'*\'`` (an asterisk), the actual width\n   is read from the next element of the tuple in *values*, and the\n   value to convert comes after the precision.\n\n6. Length modifier (optional).\n\n7. Conversion type.\n\nWhen the right argument is a dictionary (or other mapping type), then\nthe formats in the string *must* include a parenthesised mapping key\ninto that dictionary inserted immediately after the ``\'%\'`` character.\nThe mapping key selects the value to be formatted from the mapping.\nFor example:\n\n>>> print(\'%(language)s has %(number)03d quote types.\' %\n...       {\'language\': "Python", "number": 2})\nPython has 002 quote types.\n\nIn this case no ``*`` specifiers may occur in a format (since they\nrequire a sequential parameter list).\n\nThe conversion flag characters are:\n\n+-----------+-----------------------------------------------------------------------+\n| Flag      | Meaning                                                               |\n+===========+=======================================================================+\n| ``\'#\'``   | The value conversion will use the "alternate form" (where defined     |\n|           | below).                                                               |\n+-----------+-----------------------------------------------------------------------+\n| ``\'0\'``   | The conversion will be zero padded for numeric values.                |\n+-----------+-----------------------------------------------------------------------+\n| ``\'-\'``   | The converted value is left adjusted (overrides the ``\'0\'``           |\n|           | conversion if both are given).                                        |\n+-----------+-----------------------------------------------------------------------+\n| ``\' \'``   | (a space) A blank should be left before a positive number (or empty   |\n|           | string) produced by a signed conversion.                              |\n+-----------+-----------------------------------------------------------------------+\n| ``\'+\'``   | A sign character (``\'+\'`` or ``\'-\'``) will precede the conversion     |\n|           | (overrides a "space" flag).                                           |\n+-----------+-----------------------------------------------------------------------+\n\nA length modifier (``h``, ``l``, or ``L``) may be present, but is\nignored as it is not necessary for Python -- so e.g. ``%ld`` is\nidentical to ``%d``.\n\nThe conversion types are:\n\n+--------------+-------------------------------------------------------+---------+\n| Conversion   | Meaning                                               | Notes   |\n+==============+=======================================================+=========+\n| ``\'d\'``      | Signed integer decimal.                               |         |\n+--------------+-------------------------------------------------------+---------+\n| ``\'i\'``      | Signed integer decimal.                               |         |\n+--------------+-------------------------------------------------------+---------+\n| ``\'o\'``      | Signed octal value.                                   | (1)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'u\'``      | Obsolete type -- it is identical to ``\'d\'``.          | (7)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'x\'``      | Signed hexadecimal (lowercase).                       | (2)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'X\'``      | Signed hexadecimal (uppercase).                       | (2)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'e\'``      | Floating point exponential format (lowercase).        | (3)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'E\'``      | Floating point exponential format (uppercase).        | (3)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'f\'``      | Floating point decimal format.                        | (3)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'F\'``      | Floating point decimal format.                        | (3)     |\n+--------------+-------------------------------------------------------+---------+\n| ``\'g\'``      | Floating point format.

The alternate form causes a leading zero (``\'0\'``) to be inserted\n   between left-hand padding and the formatting of the number if the\n   leading character of the result is not already a zero.\n\n2. The alternate form causes a leading ``\'0x\'`` or ``\'0X\'`` (depending\n   on whether the ``\'x\'`` or ``\'X\'`` format was used) to be inserted\n   between left-hand padding and the formatting of the number if the\n   leading character of the result is not already a zero.\n\n3. The alternate form causes the result to always contain a decimal\n   point, even if no digits follow it.\n\n   The precision determines the number of digits after the decimal\n   point and defaults to 6.\n\n4. The alternate form causes the result to always contain a decimal\n   point, and trailing zeroes are not removed as they would otherwise\n   be.\n\n   The precision determines the number of significant digits before\n   and after the decimal point and defaults to 6.\n\n5. The precision determines the maximal number of characters used.\n\n1. See **PEP 237**.\n\nSince Python strings have an explicit length, ``%s`` conversions do\nnot assume that ``\'\\0\'`` is the end of the string.\n\nChanged in version 3.1: ``%f`` conversions for numbers whose absolute\nvalue is over 1e50 are no longer replaced by ``%g`` conversions.\n\nAdditional string operations are defined in standard modules\n``string`` and ``re``.\n\n\nRange Type\n==========\n\nThe ``range`` type is an immutable sequence which is commonly used for\nlooping.  The advantage of the ``range`` type is that an ``range``\nobject will always take the same amount of memory, no matter the size\nof the range it represents.\n\nRange objects have relatively little behavior: they support indexing,\ncontains, iteration, the ``len()`` function, and the following\nmethods:\n\nrange.count(x)\n\n   Return the number of *i*\'s for which ``s[i] == x``.\n\n      New in version 3.2.\n\nrange.index(x)\n\n   Return the smallest *i* such that ``s[i] == x``.

For converting the objects to strings, they have a\n``decode()`` method.\n\nWherever one of these methods needs to interpret the bytes as\ncharacters (e.g. the ``is...()`` methods), the ASCII character set is\nassumed.\n\nNote: The methods on bytes and bytearray objects don\'t accept strings as\n  their arguments, just as the methods on strings don\'t accept bytes\n  as their arguments.  For example, you have to write\n\n     a = "abc"\n     b = a.replace("a", "f")\n\n  and\n\n     a = b"abc"\n     b = a.replace(b"a", b"f")\n\nbytes.decode(encoding="utf-8", errors="strict")\nbytearray.decode(encoding="utf-8", errors="strict")\n\n   Return a string decoded from the given bytes.  Default encoding is\n   ``\'utf-8\'``. *errors* may be given to set a different error\n   handling scheme.  The default for *errors* is ``\'strict\'``, meaning\n   that encoding errors raise a ``UnicodeError``.  Other possible\n   values are ``\'ignore\'``, ``\'replace\'`` and any other name\n   registered via ``codecs.register_error()``, see section *Codec Base\n   Classes*. For a list of possible encodings, see section *Standard\n   Encodings*.\n\n   Changed in version 3.1: Added support for keyword arguments.\n\nThe bytes and bytearray types have an additional class method:\n\nclassmethod bytes.fromhex(string)\nclassmethod bytearray.fromhex(string)\n\n   This ``bytes`` class method returns a bytes or bytearray object,\n   decoding the given string object.  The string must contain two\n   hexadecimal digits per byte, spaces are ignored.\n\n   >>> bytes.fromhex(\'f0 f1f2  \')\n   b\'\\xf0\\xf1\\xf2\'\n\nThe maketrans and translate methods differ in semantics from the\nversions available on strings:\n\nbytes.translate(table[, delete])\nbytearray.translate(table[, delete])\n\n   Return a copy of the bytes or bytearray object where all bytes\n   occurring in the optional argument *delete* are removed, and the\n   remaining bytes have been mapped through the given translation\n   table, which must be a bytes object of length 256.\n\n   You can use the ``bytes.maketrans()`` method to create a\n   translation table.\n\n   Set the *table* argument to ``None`` for translations that only\n   delete characters:\n\n      >>> b\'read this short text\'.translate(None, b\'aeiou\')\n      b\'rd ths shrt txt\'\n\nstatic bytes.maketrans(from, to)\nstatic bytearray.maketrans(from, to)\n\n   This static method returns a translation table usable for\n   ``bytes.translate()`` that will map each character in *from* into\n   the character at the same position in *to*; *from* and *to* must be\n   bytes objects and have the same length.\n\n   New in version 3.1.\n',

If a target was included in the ``with`` statement, the return\n   value from ``__enter__()`` is assigned to it.\n\n   Note: The ``with`` statement guarantees that if the ``__enter__()``\n     method returns without an error, then ``__exit__()`` will always\n     be called.  Thus, if an error occurs during the assignment to the\n     target list, it will be treated the same as an error occurring\n     within the suite would be.  See step 5 below.\n\n4. The suite is executed.\n\n5. The context manager\'s ``__exit__()`` method is invoked.  If an\n   exception caused the suite to be exited, its type, value, and\n   traceback are passed as arguments to ``__exit__()``. Otherwise,\n   three ``None`` arguments are supplied.\n\n   If the suite was exited due to an exception, and the return value\n   from the ``__exit__()`` method was false, the exception is\n   reraised.  If the return value was true, the exception is\n   suppressed, and execution continues with the statement following\n   the ``with`` statement.\n\n   If the suite was exited for any reason other than an exception, the\n   return value from ``__exit__()`` is ignored, and execution proceeds\n   at the normal location for the kind of exit that was taken.\n\nWith more than one item, the context managers are processed as if\nmultiple ``with`` statements were nested:\n\n   with A() as a, B() as b:\n       suite\n\nis equivalent to\n\n   with A() as a:\n       with B() as b:\n           suite\n\nChanged in version 3.1: Support for multiple context expressions.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n',

When a generator function is called, it returns an\niterator known as a generator iterator, or more commonly, a generator.\nThe body of the generator function is executed by calling the\n``next()`` function on the generator repeatedly until it raises an\nexception.\n\nWhen a ``yield`` statement is executed, the state of the generator is\nfrozen and the value of **expression_list** is returned to\n``next()``\'s caller.  By "frozen" we mean that all local state is\nretained, including the current bindings of local variables, the\ninstruction pointer, and the internal evaluation stack: enough\ninformation is saved so that the next time ``next()`` is invoked, the\nfunction can proceed exactly as if the ``yield`` statement were just\nanother external call.\n\nThe ``yield`` statement is allowed in the ``try`` clause of a ``try``\n...  ``finally`` construct.

The context expression (the expression given in the ``with_item``)\n   is evaluated to obtain a context manager.\n\n2. The context manager\'s ``__exit__()`` is loaded for later use.\n\n3. The context manager\'s ``__enter__()`` method is invoked.\n\n4. If a target was included in the ``with`` statement, the return\n   value from ``__enter__()`` is assigned to it.\n\n   Note: The ``with`` statement guarantees that if the ``__enter__()``\n     method returns without an error, then ``__exit__()`` will always\n     be called. Thus, if an error occurs during the assignment to the\n     target list, it will be treated the same as an error occurring\n     within the suite would be. See step 6 below.\n\n5. The suite is executed.\n\n6. The context manager\'s ``__exit__()`` method is invoked.  If an\n   exception caused the suite to be exited, its type, value, and\n   traceback are passed as arguments to ``__exit__()``. Otherwise,\n   three ``None`` arguments are supplied.\n\n   If the suite was exited due to an exception, and the return value\n   from the ``__exit__()`` method was false, the exception is\n   reraised.  If the return value was true, the exception is\n   suppressed, and execution continues with the statement following\n   the ``with`` statement.\n\n   If the suite was exited for any reason other than an exception, the\n   return value from ``__exit__()`` is ignored, and execution proceeds\n   at the normal location for the kind of exit that was taken.\n\nWith more than one item, the context managers are processed as if\nmultiple ``with`` statements were nested:\n\n   with A() as a, B() as b:\n       suite\n\nis equivalent to\n\n   with A() as a:\n       with B() as b:\n           suite\n\nChanged in version 3.1: Support for multiple context expressions.\n\nSee also:\n\n   **PEP 0343** - The "with" statement\n      The specification, background, and examples for the Python\n      ``with`` statement.\n',
+ 'yield': '\nThe ``yield`` statement\n***********************\n\n   yield_stmt ::= yield_expression\n\nThe ``yield`` statement is only used when defining a generator\nfunction, and is only used in the body of the generator function.\nUsing a ``yield`` statement in a function definition is sufficient to\ncause that definition to create a generator function instead of a\nnormal function. When a generator function is called, it returns an\niterator known as a generator iterator, or more commonly, a generator.\nThe body of the generator function is executed by calling the\n``next()`` function on the generator repeatedly until it raises an\nexception.\n\nWhen a ``yield`` statement is executed, the state of the generator is\nfrozen and the value of ``expression_list`` is returned to\n``next()``\'s caller.  By "frozen" we mean that all local state is\nretained, including the current bindings of local variables, the\ninstruction pointer, and the internal evaluation stack: enough\ninformation is saved so that the next time ``next()`` is invoked, the\nfunction can proceed exactly as if the ``yield`` statement were just\nanother external call.\n\nThe ``yield`` statement is allowed in the ``try`` clause of a ``try``\n...  ``finally`` construct.  If the generator is not resumed before it\nis finalized (by reaching a zero reference count or by being garbage\ncollected), the generator-iterator\'s ``close()`` method will be\ncalled, allowing any pending ``finally`` clauses to execute.\n\nSee also:\n\n   **PEP 0255** - Simple Generators\n      The proposal for adding generators and the ``yield`` statement\n      to Python.\n\n   **PEP 0342** - Coroutines via Enhanced Generators\n      The proposal that, among other generator enhancements, proposed\n      allowing ``yield`` to appear inside a ``try`` ... ``finally``\n      block.\n'}

+# This is the main Samba configuration file. You should read the
+# smb.conf(5) manual page in order to understand the options listed

+# many!) most of which are not shown in this example
+#
+# Any line which starts with a ; (semi-colon) or a # (hash) 
+# is a comment and is ignored. In this example we will use a #
+# for commentry and a ; for parts of the config file that you
+# may wish to enable
+#
+# NOTE: Whenever you modify this file you should run the command #"testparm" # to check that you have not made any basic syntactic #errors. 
+#
+#======================= Global Settings =====================================
+[global]
+
+# 1. Server Naming Options:
+# workgroup = NT-Domain-Name or Workgroup-Name
+   
+  workgroup = MDKGROUP
+
+# netbios name is the name you will see in "Network Neighbourhood",
+# but defaults to your hostname
+

+
+# Message command is run by samba when a "popup" message is sent to it.
+# The example below is for use with LinPopUp:
+; message command = /usr/bin/linpopup "%f" "%m" %s; rm %s
+
+# 2. Printing Options:
+# CHANGES TO ENABLE PRINTING ON ALL CUPS PRINTERS IN THE NETWORK
+# (as cups is now used in linux-mandrake 7.2 by default)
+# if you want to automatically load your printer list rather
+# than setting them up individually then you'll need this
+   
+   printcap name = lpstat
+   load printers = yes
+
+# It should not be necessary to spell out the print system type unless
+# yours is non-standard. Currently supported print systems include:
+# bsd, sysv, plp, lprng, aix, hpux, qnx, cups
+   
+  printing = cups
+
+# Samba 2.2 supports the Windows NT-style point-and-print feature. To
+# use this, you need to be able to upload print drivers to the samba
+# server. The printer admins (or root) may install drivers onto samba.
+# Note that this feature uses the print$ share, so you will need to 
+# enable it below.
+# This parameter works like domain admin group:
+# printer admin = @<group> <user>
+;   printer admin = @adm
+# This should work well for winbind:
+;   printer admin = @"Domain Admins"
+
+# 3. Logging Options:

+
+# 4. Security and Domain Membership Options:
+# This option is important for security. It allows you to restrict
+# connections to machines which are on your local network. The
+# following example restricts access to two C class networks and
+# the "loopback" interface. For more examples of the syntax see

+# 7. Name Resolution Options:
+# All NetBIOS names must be resolved to IP Addresses

+# either /etc/hosts OR DNS or NIS depending on the settings of 
+# /etc/host.config, /etc/nsswitch.conf
+# and the /etc/resolv.conf file. "host" therefore is system 
+# configuration dependant. This parameter is most often of use to 
+# prevent DNS lookups
+# in order to resolve NetBIOS names to IP Addresses. Use with care!

--- This file tests base conversions from string to a decimal number
--- and back to a string (in Scientific form)
-
--- Note that unlike other operations the operand is subject to rounding
--- to conform to emax and precision settings (that is, numbers will
--- conform to rules and exponent will be in permitted range).  The
--- 'left hand side', therefore, may have numbers that cannot be
--- represented in a decDouble.  Some testcases go to the limit of the
--- next-wider format, and hence these testcases may also be used to
--- test narrowing and widening operations.

+-- This file tests base conversions from string to a decimal number

+-- and back to a string (in Scientific form)

+

+-- Note that unlike other operations the operand is subject to rounding

+-- to conform to emax and precision settings (that is, numbers will

+-- conform to rules and exponent will be in permitted range).  The

+-- 'left hand side', therefore, may have numbers that cannot be

+-- represented in a decDouble.  Some testcases go to the limit of the

+-- next-wider format, and hence these testcases may also be used to

+-- test narrowing and widening operations.

+

+precision:   16

+maxExponent: 384

+minExponent: -383

-version: 2.59
-
--- This file tests that copy operations leave uncanonical operands
--- unchanged, and vice versa
--- All operands and results are decDoubles.
-precision:   16
-maxExponent: 384
-minExponent: -383
-extended:    1
-clamp:       1
-rounding:    half_even
-
--- Uncanonical declets are: abc, where:
---   a=1,2,3
---   b=6,7,e,f
---   c=e,f
-
--- assert some standard (canonical) values; this tests that FromString
--- produces canonical results (many more in decimalNN)

+-- Note that we cannot assume add/subtract tests cover paths adequately,

+-- here, because the code might be quite different (comparison cannot

+-- overflow or underflow, so actual subtractions are not necessary).

+-- Similarly, comparetotal will have some radically different paths

+-- than compare.

+

+-- All operands and results are decDoubles.

--- This set of tests is for the eight-byte concrete representation.
--- Its characteristics are:
---
---  1 bit  sign
---  5 bits combination field
---  8 bits exponent continuation
--- 50 bits coefficient continuation
---
--- Total exponent length 10 bits
--- Total coefficient length 54 bits (16 digits)
---
--- Elimit =  767 (maximum encoded exponent)
--- Emax   =  384 (largest exponent value)
--- Emin   = -383 (smallest exponent value)
--- bias   =  398 (subtracted from encoded exponent) = -Etiny
-
--- The testcases here have only exactly representable data on the
--- 'left-hand-side'; rounding from strings is tested in 'base'
--- testcase groups.

+

+-- This set of tests is for the eight-byte concrete representation.

+-- Its characteristics are:

+--

+--  1 bit  sign

+--  5 bits combination field

+--  8 bits exponent continuation

+-- 50 bits coefficient continuation

+--

+-- Total exponent length 10 bits

+-- Total coefficient length 54 bits (16 digits)

+--

+-- Elimit =  767 (maximum encoded exponent)

+-- Emax   =  384 (largest exponent value)

+-- Emin   = -383 (smallest exponent value)

+-- bias   =  398 (subtracted from encoded exponent) = -Etiny

+

+-- The testcases here have only exactly representable data on the

+-- 'left-hand-side'; rounding from strings is tested in 'base'

+-- testcase groups.

+

+extended:    1

+clamp:       1

+precision:   16

-version: 2.59
-
--- This set of tests tests the extended specification 'round-to-integral
--- value-exact' operations (from IEEE 854, later modified in 754r).
--- All non-zero results are defined as being those from either copy or
--- quantize, so those are assumed to have been tested extensively
--- elsewhere; the tests here are for integrity, rounding mode, etc.
--- Also, it is assumed the test harness will use these tests for both
--- ToIntegralExact (which does set Inexact) and the fixed-name
--- functions (which do not set Inexact).
-
--- Note that decNumber implements an earlier definition of toIntegral
--- which never sets Inexact; the decTest operator for that is called
--- 'tointegral' instead of 'tointegralx'.

+version: 2.59

+

+-- This set of tests tests the extended specification 'round-to-integral

+-- value-exact' operations (from IEEE 854, later modified in 754r).

+-- All non-zero results are defined as being those from either copy or

+-- quantize, so those are assumed to have been tested extensively

+-- elsewhere; the tests here are for integrity, rounding mode, etc.

+-- Also, it is assumed the test harness will use these tests for both

+-- ToIntegralExact (which does set Inexact) and the fixed-name

+-- functions (which do not set Inexact).

+

+-- Note that decNumber implements an earlier definition of toIntegral

+-- which never sets Inexact; the decTest operator for that is called

+-- 'tointegral' instead of 'tointegralx'.

--- This file tests base conversions from string to a decimal number
--- and back to a string (in Scientific form)
-
--- Note that unlike other operations the operand is subject to rounding
--- to conform to emax and precision settings (that is, numbers will
--- conform to rules and exponent will be in permitted range).  The
--- 'left hand side', therefore, may have numbers that cannot be
--- represented in a decQuad.  Some testcases go to the limit of the
--- next-wider format, and hence these testcases may also be used to
--- test narrowing and widening operations.

+-- This file tests base conversions from string to a decimal number

+-- and back to a string (in Scientific form)

+

+-- Note that unlike other operations the operand is subject to rounding

+-- to conform to emax and precision settings (that is, numbers will

+-- conform to rules and exponent will be in permitted range).  The

+-- 'left hand side', therefore, may have numbers that cannot be

+-- represented in a decQuad.  Some testcases go to the limit of the

+-- next-wider format, and hence these testcases may also be used to

+-- test narrowing and widening operations.

+-- Note that we cannot assume add/subtract tests cover paths adequately,

+-- here, because the code might be quite different (comparison cannot

+-- overflow or underflow, so actual subtractions are not necessary).

+-- Similarly, comparetotal will have some radically different paths

+-- than compare.

+

+-- All operands and results are decQuads.

+-- Note that we cannot assume add/subtract tests cover paths adequately,

+-- here, because the code might be quite different (comparison cannot

+-- overflow or underflow, so actual subtractions are not necessary).

+-- Similarly, comparetotal will have some radically different paths

+-- than compare.

+

+-- All operands and results are decQuads.

-version: 2.59
-
--- This set of tests is for the sixteen-byte concrete representation.
--- Its characteristics are:
---
---   1 bit  sign
---   5 bits combination field
---  12 bits exponent continuation
--- 110 bits coefficient continuation
---
--- Total exponent length 14 bits
--- Total coefficient length 114 bits (34 digits)
---
--- Elimit = 12287 (maximum encoded exponent)
--- Emax   =  6144 (largest exponent value)
--- Emin   = -6143 (smallest exponent value)
--- bias   =  6176 (subtracted from encoded exponent) = -Etiny
-
--- The testcases here have only exactly representable data on the
--- 'left-hand-side'; rounding from strings is tested in 'base'
--- testcase groups.

+

+-- This set of tests is for the sixteen-byte concrete representation.

+-- Its characteristics are:

+--

+--   1 bit  sign

+--   5 bits combination field

+--  12 bits exponent continuation

+-- 110 bits coefficient continuation

+--

+-- Total exponent length 14 bits

+-- Total coefficient length 114 bits (34 digits)

+--

+-- Elimit = 12287 (maximum encoded exponent)

+-- Emax   =  6144 (largest exponent value)

+-- Emin   = -6143 (smallest exponent value)

+-- bias   =  6176 (subtracted from encoded exponent) = -Etiny

+

+-- The testcases here have only exactly representable data on the

+-- 'left-hand-side'; rounding from strings is tested in 'base'

+-- testcase groups.

--- These tests comprese three parts:
---   1. Sanity checks and other three-operand tests (especially those
---      where the fused operation makes a difference)
---   2. Multiply tests (third operand is neutral zero [0E+emax])
---   3. Addition tests (first operand is 1)
--- The multiply and addition tests are extensive because FMA may have
--- its own dedicated multiplication or addition routine(s), and they
--- also inherently check the left-to-right properties.

+-- These tests comprese three parts:

+--   1. Sanity checks and other three-operand tests (especially those

+--      where the fused operation makes a difference)

+--   2. Multiply tests (third operand is neutral zero [0E+emax])

+--   3. Addition tests (first operand is 1)

+-- The multiply and addition tests are extensive because FMA may have

+-- its own dedicated multiplication or addition routine(s), and they

+-- also inherently check the left-to-right properties.

-version: 2.59
-
--- This set of tests tests the extended specification 'round-to-integral
--- value-exact' operations (from IEEE 854, later modified in 754r).
--- All non-zero results are defined as being those from either copy or
--- quantize, so those are assumed to have been tested extensively
--- elsewhere; the tests here are for integrity, rounding mode, etc.
--- Also, it is assumed the test harness will use these tests for both
--- ToIntegralExact (which does set Inexact) and the fixed-name
--- functions (which do not set Inexact).
-
--- Note that decNumber implements an earlier definition of toIntegral
--- which never sets Inexact; the decTest operator for that is called
--- 'tointegral' instead of 'tointegralx'.

+version: 2.59

+

+-- This set of tests tests the extended specification 'round-to-integral

+-- value-exact' operations (from IEEE 854, later modified in 754r).

+-- All non-zero results are defined as being those from either copy or

+-- quantize, so those are assumed to have been tested extensively

+-- elsewhere; the tests here are for integrity, rounding mode, etc.

+-- Also, it is assumed the test harness will use these tests for both

+-- ToIntegralExact (which does set Inexact) and the fixed-name

+-- functions (which do not set Inexact).

+

+-- Note that decNumber implements an earlier definition of toIntegral

+-- which never sets Inexact; the decTest operator for that is called

+-- 'tointegral' instead of 'tointegralx'.

--- This file tests base conversions from string to a decimal number
--- and back to a string (in Scientific form)
-
--- Note that unlike other operations the operand is subject to rounding
--- to conform to emax and precision settings (that is, numbers will
--- conform to rules and exponent will be in permitted range).  The
--- 'left hand side', therefore, may have numbers that cannot be
--- represented in a decSingle.  Some testcases go to the limit of the
--- next-wider format, and hence these testcases may also be used to
--- test narrowing and widening operations.

+-- This file tests base conversions from string to a decimal number

+-- and back to a string (in Scientific form)

+

+-- Note that unlike other operations the operand is subject to rounding

+-- to conform to emax and precision settings (that is, numbers will

+-- conform to rules and exponent will be in permitted range).  The

+-- 'left hand side', therefore, may have numbers that cannot be

+-- represented in a decSingle.  Some testcases go to the limit of the

+-- next-wider format, and hence these testcases may also be used to

+-- test narrowing and widening operations.

--- This set of tests is for the four-byte concrete representation.
--- Its characteristics are:
---
---  1 bit  sign
---  5 bits combination field
---  6 bits exponent continuation
--- 20 bits coefficient continuation
---
--- Total exponent length 8 bits
--- Total coefficient length 24 bits (7 digits)
---
--- Elimit =  191 (maximum encoded exponent)
--- Emax   =   96 (largest exponent value)
--- Emin   =  -95 (smallest exponent value)
--- bias   =  101 (subtracted from encoded exponent) = -Etiny
-
--- The testcases here have only exactly representable data on the
--- 'left-hand-side'; rounding from strings is tested in 'base'
--- testcase groups.

+

+-- This set of tests is for the four-byte concrete representation.

+-- Its characteristics are:

+--

+--  1 bit  sign

+--  5 bits combination field

+--  6 bits exponent continuation

+-- 20 bits coefficient continuation

+--

+-- Total exponent length 8 bits

+-- Total coefficient length 24 bits (7 digits)

+--

+-- Elimit =  191 (maximum encoded exponent)

+-- Emax   =   96 (largest exponent value)

+-- Emin   =  -95 (smallest exponent value)

+-- bias   =  101 (subtracted from encoded exponent) = -Etiny

+

+-- The testcases here have only exactly representable data on the

+-- 'left-hand-side'; rounding from strings is tested in 'base'

+-- testcase groups.

--- These tests comprese three parts:
---   1. Sanity checks and other three-operand tests (especially those
---      where the fused operation makes a difference)
---   2. Multiply tests (third operand is neutral zero [0E+emax])
---   3. Addition tests (first operand is 1)
--- The multiply and addition tests are extensive because FMA may have
--- its own dedicated multiplication or addition routine(s), and they
--- also inherently check the left-to-right properties.

--- evaluated using the power operator.  The differences in results
--- (153 out of 2856) fall into the following categories:
---
---    x    ** 0.5 (x>0) has no preferred exponent, and is Inexact
---                (and hence full precision); almost all differences are
---                in this category
---    0.00 ** 0.5 becomes 0 (not 0.0), etc.
---   -0    ** 0.5 becomes 0 (never -0)
---    Some exact subnormals become inexact and hence underflows

+-- These testcases are taken from squareroot.decTest but are

+-- evaluated using the power operator.  The differences in results

+-- (153 out of 2856) fall into the following categories:

+--

+--    x    ** 0.5 (x>0) has no preferred exponent, and is Inexact

+--                (and hence full precision); almost all differences are

+--                in this category

+--    0.00 ** 0.5 becomes 0 (not 0.0), etc.

+--   -0    ** 0.5 becomes 0 (never -0)

+--    Some exact subnormals become inexact and hence underflows

--N Put coverage files alongside modules.

--s means to run only a single test and exit.  This is useful when

-/tmp).
+-s On the first invocation of regrtest using -s, the first test file found
+or the first test file given on the command line is run, and the name of
+the next test is recorded in a file named pynexttest.  If run from the
+Python build directory, pynexttest is located in the 'build' subdirectory,
+otherwise it is located in tempfile.gettempdir().  On subsequent runs,
+the test in pynexttest is run, and the next test is written to pynexttest.
+When the last test has been run, pynexttest is deleted.  In this way it
+is possible to single step through the test files.  This is useful when
+doing memory analysis on the Python interpreter, which process tends to
+consume too many resources to run the full regression test non-stop.

+Python unit testing framework, based on Erich Gamma's JUnit and Kent Beck's
+Smalltalk testing framework.
+
+This module contains the core framework classes that form the basis of
+specific test cases and suites (TestCase, TestSuite etc.), and also a
+text-based utility class for running the tests and reporting the results
+ (TextTestRunner).
+
+Simple usage:
+
+    import unittest
+
+    class IntegerArithmenticTestCase(unittest.TestCase):
+        def testAdd(self):  ## test method names begin 'test*'
+            self.assertEqual((1 + 2), 3)
+            self.assertEqual(0 + 1, 1)
+        def testMultiply(self):
+            self.assertEqual((0 * 10), 0)
+            self.assertEqual((5 * 8), 40)
+
+    if __name__ == '__main__':
+        unittest.main()

+Building a Python Mac OS X distribution
+=======================================
 
-The ``build-install.py`` script creates MacPython distributions, including

+The ``build-install.py`` script creates Python distributions, including
+certain third-party libraries as necessary.  It builds a complete 
 framework-based Python out-of-tree, installs it in a funny place with 
 $DESTROOT, massages that installation to remove .pyc files and such, creates 
 an Installer package from the installation plus other files in ``resources`` 
 and ``scripts`` and placed that on a ``.dmg`` disk image.
 
-Prerequisites
--------------
+As of Python 2.7.x and 3.2, PSF practice is to build two installer variants
+for each release:
 
-* A MacOS X 10.4 (or later)
+1.  32-bit-only, i386 and PPC universal, capable on running on all machines
+    supported by Mac OS X 10.3.9 through (at least) 10.6::
 
-* XCode 2.2 (or later), with the universal SDK
+        python build-installer.py \
+            --sdk-path=/Developer/SDKs/MacOSX10.4u.sdk \
+            --universal-archs=32-bit \
+            --dep-target=10.3 
+            # These are the current default options
 
-* No Fink (in ``/sw``) or DarwinPorts (in ``/opt/local``), those could
+    - builds the following third-party libraries
+
+        * Bzip2
+        * Zlib 1.2.3
+        * GNU Readline (GPL)
+        * SQLite 3
+        * NCurses
+        * Oracle Sleepycat DB 4.8 (Python 2.x only)
+
+    - requires ActiveState ``Tcl/Tk 8.4`` (currently 8.4.19) to be installed for building
+
+    - current target build environment:
+        
+        * Mac OS X 10.5.8 PPC or Intel
+        * Xcode 3.1.4 (or later)
+        * ``MacOSX10.4u`` SDK (later SDKs do not support PPC G3 processors)
+        * ``MACOSX_DEPLOYMENT_TARGET=10.3``
+        * Apple ``gcc-4.0``
+        * Python 2.n (n >= 4) for documentation build with Sphinx
+
+    - alternate build environments:
+
+        * Mac OS X 10.4.11 with Xcode 2.5
+        * Mac OS X 10.6.6 with Xcode 3.2.5
+            - need to change ``/System/Library/Frameworks/{Tcl,Tk}.framework/Version/Current`` to ``8.4``
+
+2.  64-bit / 32-bit, x86_64 and i386 universal, for OS X 10.6 (and later)::
+
+        python build-installer.py \
+            --sdk-path=/Developer/SDKs/MacOSX10.6.sdk \
+            --universal-archs=intel \
+            --dep-target=10.6
+
+    - uses system-supplied versions of third-party libraries
+    
+        * readline module links with Apple BSD editline (libedit)
+        * builds Oracle Sleepycat DB 4.8 (Python 2.x only)
+
+    - requires ActiveState Tcl/Tk 8.5.9 (or later) to be installed for building
+
+    - current target build environment:
+        
+        * Mac OS X 10.6.6 (or later)
+        * Xcode 3.2.5 (or later)
+        * ``MacOSX10.6`` SDK
+        * ``MACOSX_DEPLOYMENT_TARGET=10.6``
+        * Apple ``gcc-4.2``
+        * Python 2.n (n >= 4) for documentation build with Sphinx
+
+    - alternate build environments:
+
+        * none
+
+
+General Prerequisites
+---------------------
+
+* No Fink (in ``/sw``) or MacPorts (in ``/opt/local``) or other local
+  libraries or utilities (in ``/usr/local``) as they could
   interfere with the build.
 
-* The documentation for the release must be available on python.org
+* The documentation for the release is built using Sphinx
   because it is included in the installer.
 
+* It is safest to start each variant build with an empty source directory
+  populated with a fresh copy of the untarred source.
+

-Building a 4-way universal installer
-....................................
+Building other universal installers
+...................................
 
 It is also possible to build a 4-way universal installer that runs on 
-OSX Leopard or later::
+OS X Leopard or later::
 
-  $ ./build-installer.py --dep-target=10.5 --universal-archs=all --sdk=/
+  python 2.6 /build-installer.py \
+        --dep-target=10.5
+        --universal-archs=all
+        --sdk-path=/Developer/SDKs/MacOSX10.5.sdk
 
-This requires that the deployment target is 10.5 (or later), and hence
-also that your building on at least OSX 10.5.
-
-Testing
--------
-
-The resulting binaries should work on MacOSX 10.3.9 or later. I usually run
-the installer on a 10.3.9, a 10.4.x PPC and a 10.4.x Intel system and then
-run the testsuite to make sure.
+This requires that the deployment target is 10.5, and hence
+also that you are building on at least OS X 10.5.  4-way includes
+``i386``, ``x86_64``, ``ppc``, and ``ppc64`` (G5).  ``ppc64`` executable
+variants can only be run on G5 machines running 10.5.  Note that,
+while OS X 10.6 is only supported on Intel-based machines, it is possible
+to run ``ppc`` (32-bit) executables unmodified thanks to the Rosetta ppc
+emulation in OS X 10.5 and 10.6.
 
+Other ``--universal-archs`` options are ``64-bit`` (``x86_64``, ``ppc64``),
+and ``3-way`` (``ppc``, ``i386``, ``x86_64``).  None of these options
+are regularly exercised; use at your own risk.
 
-Announcements
--------------
 
-(This is mostly of historic interest)
+Testing
+-------
 
-When all is done, announcements can be posted to at least the following
-places:
--   pythonmac-sig@python.org
--   python-dev@python.org
--   python-announce@python.org
--   archivist@info-mac.org
--   adcnews@apple.com
--   news@macnn.com
--   http://www.macupdate.com
--   http://guide.apple.com/usindex.lasso
--   http://www.apple.com/downloads/macosx/submit
--   http://www.versiontracker.com/ (userid Jack.Jansen@oratrix.com)
--   http://www.macshareware.net (userid jackjansen)
+Ideally, the resulting binaries should be installed and the test suite run
+on all supported OS X releases and architectures.  As a practical matter,
+that is generally not possible.  At a minimum, variant 1 should be run on
+at least one Intel, one PPC G4, and one PPC G3 system and one each of 
+OS X 10.6, 10.5, 10.4, and 10.3.9.  Not all tests run on 10.3.9.
+Variant 2 should be run on 10.6 in both 32-bit and 64-bit modes.::
+
+    arch -i386 /usr/local/bin/pythonn.n -m test.regrtest -w -u all 
+    arch -X86_64 /usr/local/bin/pythonn.n -m test.regrtest -w -u all
+    
+Certain tests will be skipped and some cause the interpreter to fail
+which will likely generate ``Python quit unexpectedly`` alert messages
+to be generated at several points during a test run.  These can
+be ignored.

+*Release date: 13-Nov-2010*
 
 Core and Builtins
 -----------------
 
+- Issue #10372: Import the warnings module only after the IO library is
+  initialized, so as to avoid bootstrap issues with the '-W' option.
+
+- Issue #10293: Remove obsolete field in the PyMemoryView structure, unused
+  undocumented value PyBUF_SHADOW, and strangely-looking code in
+  PyMemoryView_GetContiguous.
+
+- Issue #6081: Add str.format_map(), similar to ``str.format(**mapping)``.
+
+- If FileIO.__init__ fails, close the file descriptor.
+
 - Issue #10221: dict.pop(k) now has a key error message that includes the
   missing key (same message d[k] returns for missing keys).
 
-- Issue #5437: A preallocated MemoryError instance should not hold traceback
+- Issue #5437: A preallocated MemoryError instance should not keep traceback
   data (including local variables caught in the stack trace) alive infinitely.
 
-- Issue #10077: Fix logging of site module errors at startup.
-
 - Issue #10186: Fix the SyntaxError caret when the offset is equal to the length
   of the offending line.
 
-- Issue #9713, #10114: Parser functions (eg. PyParser_ASTFromFile) expects
-  filenames encoded to the filesystem encoding with surrogateescape error
-  handler (to support undecodable bytes), instead of UTF-8 in strict mode.
+- Issue #10089: Add support for arbitrary -X options on the command line.  They
+  can be retrieved through a new attribute ``sys._xoptions``.
 
-- Issue #10006: type.__abstractmethods__ now raises an AttributeError.  As a
-  result metaclasses can now be ABCs (see #9533).
+- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
+  the locale encoding.  If the LANG (and LC_ALL and LC_CTYPE) environment
+  variable is not set, the locale encoding is ISO-8859-1, whereas most programs
+  (including Python) expect UTF-8.  Python already uses UTF-8 for the filesystem
+  encoding and to encode command line arguments on this OS.
+
+- Issue #9713, #10114: Parser functions (e.g. PyParser_ASTFromFile) expect
+  filenames encoded to the filesystem encoding with the surrogateescape error
+  handler (to support undecodable bytes), instead of UTF-8 in strict mode.
 
 - Issue #9997: Don't let the name "top" have special significance in scope
   resolution.
 
-- Issue #9930: Remove bogus subtype check that was causing (e.g.)
-  float.__rdiv__(2.0, 3) to return NotImplemented instead of the
-  expected 1.5.
+- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as
+  the default 512 when compiling on AIX.
 
-- Issue #9804: ascii() now always represents unicode surrogate pairs as
-  a single ``\UXXXXXXXX``, regardless of whether the character is printable
-  or not.  Also, the "backslashreplace" error handler now joins surrogate
-  pairs into a single character on UCS-2 builds.
+- Use locale encoding instead of UTF-8 to encode and decode filenames if
+  Py_FileSystemDefaultEncoding is not set.
 
-- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
-  thread-local storage key.
+- Issue #10095: fp_setreadl() doesn't reopen the file, instead reuse the file
+  descriptor.
 
-- Issue #9737: Fix a crash when trying to delete a slice or an item from
-  a memoryview object.
+- Issue #9418: Moved private string methods ``_formatter_parser`` and
+  ``_formatter_field_name_split`` into a new ``_string`` module.
 
-- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
-  properly.  Patch by Stefan Behnel.
+- Issue #9992: Remove PYTHONFSENCODING environment variable.
 
-- Restore GIL in nis_cat in case of error.
+Library
+-------
 
-- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
+- Issue #10465: fix broken delegating of attributes by gzip._PaddedFile.
 
-- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
+- Issue #10356: Decimal.__hash__(-1) should return -2.
 
-- Issue #5319: Print an error if flushing stdout fails at interpreter
-  shutdown.
+- Issue #1553375: logging: Added stack_info kwarg to display stack information.
 
-- Issue #8814: function annotations (the ``__annotations__`` attribute)
-  are now included in the set of attributes copied by default by
-  functools.wraps and functools.update_wrapper.  Patch by Terrence Cole.
+- Issue #5111: IPv6 Host in the Header is wrapped inside [ ]. Patch by Chandru.
 
-- Issue #83755:  Implicit set-to-frozenset conversion was not thread-safe.
+- Fix Fraction.__hash__ so that Fraction.__hash__(-1) is -2.  (See also issue
+  #10356.)
 
-- Issue #10068: Global objects which have reference cycles with their module's
-  dict are now cleared again. This causes issue #7140 to appear again.
+- Issue #4471: Add the IMAP.starttls() method to enable encryption on standard
+  IMAP4 connections.  Original patch by Lorenzo M. Catucci.
 
-- Issue #9416: Fix some issues with complex formatting where the
-  output with no type specifier failed to match the str output:
+- Issue #1466065: Add 'validate' option to base64.b64decode to raise an error if
+  there are non-base64 alphabet characters in the input.
 
-    - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
-    - format(complex(0.0, 2.0), '-') included a sign and parentheses.
+- Issue #10386: Add __all__ to token module; this simplifies importing in
+  tokenize module and prevents leaking of private names through ``import *``.
 
-- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
-  compiler.
+- Issue #4471: Properly shutdown socket in IMAP.shutdown().  Patch by Lorenzo
+  M. Catucci.
 
-- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
-  start byte and the continuation byte(s) are now considered invalid, instead
-  of the number of bytes specified by the start byte.
-  E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
-  replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
-  ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
-  Previous versions returned a single u'\ufffd'.
+- Fix IMAP.login() to work properly.
 
-- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
-  Fix the encoding of the modules filename. Patch written by Amaury Forgeot
-  d'Arc.
+- Issue #9244: multiprocessing pool worker processes could terminate
+  unexpectedly if the return value of a task could not be pickled.  Only the
+  ``repr`` of such errors are now sent back, wrapped in an
+  ``MaybeEncodingError`` exception.
 
-- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
+- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of
+  ``multiprocessing.Pool`` now accepts a ``error_callback`` argument.  This can
+  be a callback with the signature ``callback(exc)``, which will be called if
+  the target raises an exception.
 
-- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
-  the interpreter with characters outside the Basic Multilingual Plane
-  (higher than 0x10000).
+- Issue #10022: The dictionary returned by the ``getpeercert()`` method of SSL
+  sockets now has additional items such as ``issuer`` and ``notBefore``.

-  large.
+- ``usenetrc`` is now false by default for NNTP objects.
 
-- Issue #8766: Initialize _warnings module before importing the first module.
-  Fix a crash if an empty directory called "encodings" exists in sys.path.
+- Issue #1926: Add support for NNTP over SSL on port 563, as well as STARTTLS.
+  Patch by Andrew Vant.
 
-- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
-  (instead of strict) error handler to escape surrogates
+- Issue #10335: Add tokenize.open(), detect the file encoding using
+  tokenize.detect_encoding() and open it in read only mode.
 
-- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
-  indirectly Python signal handlers anymore because mywrite() ignores
-  exceptions (KeyboardInterrupt)
+- Issue #10321: Add support for binary data to smtplib.SMTP.sendmail, and a new
+  method send_message to send an email.message.Message object.
 
-- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
-  unicode string (eg. backslashreplace)
+- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
+  handler to parse the Makefile file.  Avoid a UnicodeDecodeError if the source
+  code directory name contains a non-ASCII character and the locale encoding is
+  ASCII.
 
-- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
-  PyMemberDefs could produce an internal error;  raise TypeError instead.
+- Issue #10329: The trace module writes reports using the input Python script
+  encoding, instead of the locale encoding.  Patch written by Alexander
+  Belopolsky.
 
-- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
-  passed to bytes or bytearray.
+- Issue #10126: Fix distutils' test_build when Python was built with
+  --enable-shared.
 
-- Issue #8329: Don't return the same lists from select.select when no fds are
-  changed.
+- Issue #9281: Prevent race condition with mkdir in distutils.  Patch by
+  Arfrever.
 
-- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
+- Issue #10229: Fix caching error in gettext.
 
-- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
-  is unknown
+- Issue #10252: Close file objects in a timely manner in distutils code and
+  tests.  Patch by Brian Brazil, completed by Éric Araujo.
 
-- Issue #1583863: An str subclass can now override the __str__ method
+- Issue #10180: Pickling file objects is now explicitly forbidden, since
+  unpickling them produced nonsensical results.
 
-- Issue #7072: isspace(0xa0) is true on Mac OS X
+- Issue #10311: The signal module now restores errno before returning from its
+  low-level signal handler.  Patch by Hallvard B Furuseth.
 
-C-API
------
+- Issue #10282: Add a ``nntp_implementation`` attribute to NNTP objects.
 
-- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
-  PySequence_DelSlice when the object doesn't have any mapping operations
-  defined.
+- Issue #10283: Add a ``group_pattern`` argument to NNTP.list().
 
-- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
-  embedders of the interpreter to set sys.argv without also modifying
-  sys.path.  This helps fix `CVE-2008-5983
-  <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
+- Issue #10155: Add IISCGIHandler to wsgiref.handlers to support IIS CGI
+  environment better, and to correct unicode environment values for WSGI 1.0.1.
 
-Library
--------
+- Issue #10281: nntplib now returns None for absent fields in the OVER/XOVER
+  response, instead of raising an exception.
 
-- Issue #5111: IPv6 Host in the Header is wrapped inside [ ]. Patch by Chandru.
+- wsgiref now implements and validates PEP 3333, rather than an experimental
+  extension of PEP 333.  (Note: earlier versions of Python 3.x may have
+  incorrectly validated some non-compliant applications as WSGI compliant; if
+  your app validates with Python <3.2b1+, but not on this version, it is likely
+  the case that your app was not compliant.)
 
-- Issue #4471: Properly shutdown socket in IMAP.shutdown().  Patch by
-  Lorenzo M. Catucci.

+
+What's New in Python 3.2 Alpha 3?
+=================================
+
+*Release date: 09-Oct-2010*
+
+Core and Builtins
+-----------------
+
+- Issue #10068: Global objects which have reference cycles with their module's
+  dict are now cleared again. This causes issue #7140 to appear again.
+
+- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
+  encodings.
+
+- ast.literal_eval() can now handle negative numbers.  It is also a little more
+  liberal in what it accepts without compromising the safety of the evaluation.
+  For example, 3j+4 and 3+4+5 are both accepted.
+
+- Issue #10006: type.__abstractmethods__ now raises an AttributeError.  As a
+  result metaclasses can now be ABCs (see #9533).
+
+- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
+
+- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
+  UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
+  32 bits wchar_t (eg. Linux in narrow build).
+
+- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
+  introduced by issue #9324.
+
+- Issue #9979: Create function PyUnicode_AsWideCharString().
+
+- Issue #7397: Mention that importlib.import_module() is probably what someone
+  really wants to be using in __import__'s docstring.
+
+- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
+  to use named arguments.
+
+- Issue #9930: Remove bogus subtype check that was causing (e.g.)
+  float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
+
+- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
+
+- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
+  threads are still running.  Instead, reinitialize the GIL on a second call to
+  Py_Initialize().
+
+- All SyntaxErrors now have a column offset and therefore a caret when the error
+  is printed.
+
+- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
+  module that was imported, but instead gets the module from sys.modules.
+
+- Issue #9213: The range type_items now provides index() and count() methods, to
+  conform to the Sequence ABC.  Patch by Daniel Urban and Daniel Stutzbach.
+
+- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
+  with a non-empty format string.  This is an effort to future-proof user
+  code. If a derived class does not currently implement __format__ but later
+  adds its own __format__, it would most likely break user code that had
+  supplied a format string.  This will be changed to a DeprecationWaring in
+  Python 3.3 and it will be an error in Python 3.4.
+
+- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
+  re-created on a subsequent call to Py_Initialize().  The problem (a crash)
+  wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
+
+- Issue #9210: Configure option --with-wctype-functions was removed.  Using the
+  functions from the libc caused the methods .upper() and lower() to become
+  locale aware and created subtly wrong results.
+
+- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
+  non-ASCII byte in the format string.
+
+- Issue #4617: Previously it was illegal to delete a name from the local
+  namespace if it occurs as a free variable in a nested block.  This limitation
+  of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
+
+- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
+  ``\UXXXXXXXX``, regardless of whether the character is printable or not.
+  Also, the "backslashreplace" error handler now joins surrogate pairs into a
+  single character on UCS-2 builds.
+

 Core and Builtins
 -----------------
 
-- Issue #7544: Preallocate thread memory before creating the thread to avoid
-  a fatal error in low memory condition.
+- Issue #8991: convertbuffer() rejects discontigious buffers.
+
+- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
+  compiler.
+
+- Issue #8413: structsequence now subclasses tuple.
+
+- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
+  start byte and the continuation byte(s) are now considered invalid, instead of
+  the number of bytes specified by the start byte.  E.g.:
+  '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
+  with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
+  even if '\xf1' is the start byte of a 4-bytes sequence.  Previous versions
+  returned a single u'\ufffd'.
+
+- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
+  rather than 0.0.  So "-7j" is now exactly equivalent to "-(7j)".
+
+- Be more specific in error messages about positional arguments.
+
+- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
+  objects, as described in the documentation.
+
+- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
+  Fix the encoding of the modules filename.  Patch written by Amaury Forgeot
+  d'Arc.
+
+- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
+  dealing with unary minus applied to a constant.  The removed code was mutating
+  the ST, causing a second compilation to fail.
+
+- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
+  mode raises unicode errors.  The encoder only supports "strict" and "replace"
+  error handlers, the decoder only supports "strict" and "ignore" error
+  handlers.  Patch written by Mark Hammond.
+
+- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
+  "w*" format instead. Add tests for "w*" format.
+
+- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
+  formats if the string contains a null byte/character.  Write unit tests for
+  string formats.
+
+- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
+  suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
+  location of the raised exception.
+
+- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
+  filenames and enable os.fsencode().
+
+- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
+
+- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
+  interpreter with characters outside the Basic Multilingual Plane (higher than
+  0x10000).
+
+- Issue #8950: (See also issue #5080).  Py_ArgParse*() functions now raise
+  TypeError instead of giving a DeprecationWarning when a float is parsed using
+  the 'L' code (for long long).  (All other integer codes already raise
+  TypeError in this case.)
+
+- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
+  enable shortcuts for upper case encoding name. Add also a shortcut for
+  "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
+
+- Issue #8838: Remove codecs.charbuffer_encode() function.  The buffer protocol
+  doesn't support "char buffer" anymore in Python 3.
+
+- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
+  instead.  codecs.charbuffer_encode() now accepts modifiable buffer objects
+  like bytearray.
+
+- Issue #8837: Remove "O?" format of PyArg_Parse*() functions.  The format is no
+  used anymore and it was never documented.
+
+- In str.format(), raise a ValueError when indexes to arguments are too large.
+
+- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
+  integers n (including n = -909).
+
+- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
+  of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
+  easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
+  equal value.
+
+- Issue #8748: Fix two issues with comparisons between complex and integer
+  objects.  (1) The comparison could incorrectly return True in some cases
+  (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
+  (2) The comparison raised an OverflowError for large integers, leading to
+  unpredictable exceptions when combining integers and complex objects in sets
+  or dicts.
+
+- Issue #8766: Initialize _warnings module before importing the first module.
+  Fix a crash if an empty directory called "encodings" exists in sys.path.
+
+- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
+  encoding and surrogateescape error handler instead of the locale encoding to
+  be consistent with os.environ.  Add PySys_AddWarnOptionUnicode() function.
+
+- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
+  of strict) error handler to escape surrogates.
+
+- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
+  object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
+  handler, and return bytes.  If Py_FileSystemDefaultEncoding is not set, fall
+  back to UTF-8.
+
+- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
+  error handler, not only the default error handler (strict).
+
+- Issue #8610: Load file system codec at startup, and display a fatal error on
+  failure.  Set the file system encoding to utf-8 (instead of None) if getting
+  the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
+
+- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
+  PyUnicode_FromString() to support surrogates in the filename and use the right
+  encoding.
+
+- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
+
+- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
+
+- Issue #8419: Prevent the dict constructor from accepting non-string keyword
+  arguments.
+
+- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
+  indirectly Python signal handlers anymore because mywrite() ignores exceptions
+  (KeyboardInterrupt).
+
+- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
+  unicode string (eg. backslashreplace).
+
+- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
+  anymore, you have to convert your bytearray filenames to bytes.
+
+- Issue #7332: Remove the 16KB stack-based buffer in
+  PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
+  compared to the dynamic memory allocation fallback.  Patch by Charles-François
+  Natali.
+
+- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
+  passed to bytes or bytearray.
+
+- Issue #7301: Add environment variable $PYTHONWARNINGS.
+
+- Issue #8329: Don't return the same lists from select.select when no fds are
+  changed.
+
+- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
+  64-bit machines.  The shift count for either left or right shift is permitted
+  to be up to sys.maxsize.
+
+- Ensure that tokenization of identifiers is not affected by locale.
 
-- Issue #7820: The parser tokenizer restores all bytes in the right if
-  the BOM check fails.
+- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
+
+- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
+
+- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
+  is set.
+
+- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
+  is unknown.
+
+- Issue #1583863: A str subclass can now override the __str__ method.
+
+- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
+  PyMemberDefs could produce an internal error; raise TypeError instead.
+
+- Issue #7845: Rich comparison methods on the complex type now return
+  NotImplemented rather than raising a TypeError when comparing with an
+  incompatible type; this allows user-defined classes to implement their own
+  comparisons with complex.
+
+- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
+  (SIGINT). If an error occurs while importing the site module, the error is
+  printed and Python exits. Initialize the GIL before importing the site module.
+
+- Issue #7173: Generator finalization could invalidate sys.exc_info().
+
+- Issue #7544: Preallocate thread memory before creating the thread to avoid a
+  fatal error in low memory condition.
+
+- Issue #7820: The parser tokenizer restores all bytes in the right if the BOM
+  check fails.
 
 - Handle errors from looking up __prepare__ correctly.

 - Issue #7309: Fix unchecked attribute access when converting
-  UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
-  strings.
+  UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to strings.
+
+- Issue #6902: Fix problem with built-in types format incorrectly with 0
+  padding.
+
+- Issue #7988: Fix default alignment to be right aligned for complex.__format__.
+  Now it matches other numeric types.
+
+- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
+  PyOS_ascii_strtod, and PyOS_ascii_atof.  Use PyOS_double_to_string and
+  PyOS_string_to_double instead.  See issue #5835 for the original deprecations.
+
+- Issue #7385: Fix a crash in `MemoryView_FromObject` when `PyObject_GetBuffer`
+  fails.  Patch by Florent Xicluna.
 
-- Issue #6902: Fix problem with built-in types format incorrectly with
-  0 padding.
+- Issue #7788: Fix an interpreter crash produced by deleting a list slice with
+  very large step value.
 
-- Issue #7988: Fix default alignment to be right aligned for
-  complex.__format__. Now it matches other numeric types.
+- Issue #7766: Change sys.getwindowsversion() return value to a named tuple and
+  add the additional members returned in an OSVERSIONINFOEX structure.  The new
+  members are service_pack_major, service_pack_minor, suite_mask, and
+  product_type.
 
-- Issue #7385: Fix a crash in `MemoryView_FromObject` when
-  `PyObject_GetBuffer` fails.  Patch by Florent Xicluna.
+- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`) could
+  crash in many places because of the PyByteArray_AS_STRING() macro returning
+  NULL.  The macro now returns a statically allocated empty string instead.
 
-- Issue #7788: Fix an interpreter crash produced by deleting a list
-  slice with very large step value.
+- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
+  where the right hand operand is a set of constants, by turning the set into a
+  frozenset and pre-building it as a constant.  The comparison operation is made
+  against the constant instead of building a new set each time it is executed (a
+  similar optimization already existed which turned a list of constants into a
+  pre-built tuple).  Patch and additional tests by Dave Malcolm.
 
-- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
-  could crash in many places because of the PyByteArray_AS_STRING() macro
-  returning NULL.  The macro now returns a statically allocated empty
-  string instead.
+- Issue #7622: Improve the split(), rsplit(), splitlines() and replace() methods
+  of bytes, bytearray and unicode objects by using a common implementation based
+  on stringlib's fast search.  Patch by Florent Xicluna.
 
-- Issue #7632: Fix various str -> float conversion bugs present in 2.7
-  alpha 2, including: (1) a serious 'wrong output' bug that could
-  occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
-  that occurred in debug builds when parsing certain long numeric
-  strings corresponding to subnormal values, (3) a memory leak for
-  some values large enough to cause overflow, and (4) a number of
-  flaws that could lead to incorrectly rounded results.

-  in the middle of populating a tuple.  Patch by Florent Xicluna.
+- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
+  in ** operator.  The behaviour now conforms to that described in C99 Annex F.
+
+- Issue #1811: improve accuracy and cross-platform consistency for true division
+  of integers: the result of a/b is now correctly rounded for ints a and b (at
+  least on IEEE 754 platforms), and in particular does not depend on the
+  internal representation of an int.
+
+- Issue #6834: replace the implementation for the 'python' and 'pythonw'

+
+  These executables now work properly with the arch(1) command: ``arch -ppc
+  python`` will start a universal binary version of python in PPC mode (unlike
+  previous releases).

+
+- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
+  allocator will be automatically disabled when running under Valgrind.  This
+  gives improved memory leak detection when running under Valgrind, while taking
+  advantage of pymalloc at other times.

-=============
-
-If you want to edit Python code in Emacs, you should download python-mode.el
-and install it somewhere on your load-path.  See the project page to download:
-
-    https://launchpad.net/python-mode
-
-While Emacs comes with a python.el file, it is not recommended.
-python-mode.el is maintained by core Python developers and is generally
-considered more Python programmer friendly.  For example, python-mode.el
-includes a killer feature called `pdbtrack` which allows you to set a pdb
-breakpoint in your code, run your program in an Emacs shell buffer, and do gud
-style debugging when the breakpoint is hit.
-
-python-mode.el is compatible with both GNU Emacs from the FSF, and XEmacs.
-

-
-Each warning has a unique id and comments that can be made on it.
-When checking in changes due to a K7 report, the unique id

-A comment was added to the K7 warning indicating the SVN revision

-
-False positives were also annotated so that the comments can

-To:  python-list
-Subject: comp.lang.python RFD again
-From: Guido.van.Rossum@cwi.nl
-
-I've followed the recent discussion and trimmed the blurb RFD down a bit
-(and added the word "object-oriented" to the blurb).
-
-I don't think it's too early to *try* to create the newsgroup --
-whether we will succeed may depend on how many Python supporters there
-are outside the mailing list.
-
-I'm personally not worried about moderation, and anyway I haven't
-heard from any volunteers for moderation (and I won't volunteer
-myself) so I suggest that we'll continue to ask for one unmoderated
-newsgroup.
-
-My next action will be to post an updated FAQ (which will hint at the
-upcoming RFD) to comp.lang.misc; then finalize the 1.0.0 release and
-put it on the ftp site.  I'll also try to get it into
-comp.sources.unix or .misc.  And all this before the end of January!
-
---Guido van Rossum, CWI, Amsterdam <Guido.van.Rossum@cwi.nl>
-URL:  <http://www.cwi.nl/cwi/people/Guido.van.Rossum.html>
-
-======================================================================
-
-These are the steps required (in case you don't know about the
-newsgroup creation process):
-
-First, we need to draw up an RFD (Request For Discussion).  This is a
-document that tells what the purpose of the group is, and gives a case
-for its creation.  We post this to relevant groups (comp.lang.misc,
-the mailing list, news.groups, etc.)  Discussion is held on
-news.groups.
-
-Then, after a few weeks, we run the official CFV (Call For Votes).
-The votes are then collected over a period of weeks.  We need 100 more
-yes votes than no votes, and a 2/3 majority, to get the group.
-
-There are some restrictions on the vote taker: [s]he cannot actively
-campaign for/against the group during the vote process.  So the main
-benefit to Steve instead of me running the vote is that I will be free
-to campaign for its creation!
-
-The following is our current draft for the RFD.
-
-======================================================================
-
-Request For Discussion: comp.lang.python
-
-
-Purpose
--------
-
-The newsgroup will be for discussion on the Python computer language.
-Possible topics include requests for information, general programming,
-development, and bug reports. The group will be unmoderated.
-
-
-What is Python?
----------------
-
-Python is a relatively new very-high-level language developed in
-Amsterdam.  Python is a simple, object-oriented procedural language,
-with features taken from ABC, Icon, Modula-3, and C/C++.
-
-Its central goal is to provide the best of both worlds: the dynamic
-nature of scripting languages like Perl/TCL/REXX, but also support for
-general programming found in the more traditional languages like Icon,
-C, Modula,...
-
-Python may be FTP'd from the following sites:
-
-	ftp.cwi.nl in directory /pub/python (its "home site", also has a FAQ)
-	ftp.uu.net in directory /languages/python
-	gatekeeper.dec.com in directory /pub/plan/python/cwi
-
-
-Rationale
----------
-
-Currently there is a mailing list with over 130 subscribers.
-The activity of this list is high, and to make handling the
-traffic more reasonable, a newsgroup is being proposed. We
-also feel that comp.lang.misc would not be a suitable forum
-for this volume of discussion on a particular language.
-
-
-Charter
--------
-
-Comp.lang.python is an unmoderated newsgroup which will serve
-as a forum for discussing the Python computer language. The
-group will serve both those who just program in Python and
-those who work on developing the language. Topics that
-may be discussed include:
-
-	- announcements of new versions of the language and
-	  applications written in Python.
-
-	- discussion on the internals of the Python language.
-
-	- general information about the language.
-
-	- discussion on programming in Python.
-
-
-Discussion
-----------
-
-Any objections to this RFD will be considered and, if determined
-to be appropriate, will be incorporated. The discussion period
-will be for a period of 21 days after which the first CFV will be
-issued.

-
-python [-diOStuUvxX?] [-c command | script | - ] [args]
-
-                              Invocation Options
-Option                                  Effect
--c cmd  program passed in as string (terminates option list)
--d      Outputs parser debugging information (also PYTHONDEBUG=x)
--E      ignore environment variables (such as PYTHONPATH)
--h      print this help message and exit
--i      Inspect interactively after running script (also PYTHONINSPECT=x) and
-        force prompts, even if stdin appears not to be a terminal
--m mod  run library module as a script (terminates option list
--O      optimize generated bytecode (a tad; also PYTHONOPTIMIZE=x)
--OO     remove doc-strings in addition to the -O optimizations
--Q arg  division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew
--S      Don't perform 'import site' on initialization
--u      Unbuffered binary stdout and stderr (also PYTHONUNBUFFERED=x).
--v      Verbose (trace import statements) (also PYTHONVERBOSE=x)
--W arg : warning control (arg is action:message:category:module:lineno)
--x      Skip first line of source, allowing use of non-unix Forms of #!cmd
--?      Help!
--c      Specify the command to execute (see next section). This terminates the
-command option list (following options are passed as arguments to the command).
-        the name of a python file (.py) to execute read from stdin.
-script  Anything afterward is passed as options to python script or command,
-        not interpreted as an option to interpreter itself.
-args    passed to script or command (in sys.argv[1:])
-        If no script or command, Python enters interactive mode.

-Environment variables
-
-                             Environment variables
-    Variable                                 Effect
-PYTHONHOME       Alternate prefix directory (or prefix;exec_prefix). The
-                 default module search path uses prefix/lib
-                 Augments the default search path for module files. The format
-                 is the same as the shell's $PATH: one or more directory
-                 pathnames separated by ':' or ';' without spaces around
-                 (semi-)colons!
-PYTHONPATH       On Windows first search for Registry key HKEY_LOCAL_MACHINE\
-                 Software\Python\PythonCore\x.y\PythonPath (default value). You
-                 may also define a key named after your application with a
-                 default string value giving the root directory path of your
-                 app.
-                 If this is the name of a readable file, the Python commands in
-PYTHONSTARTUP    that file are executed before the first prompt is displayed in
-                 interactive mode (no default).
-PYTHONDEBUG      If non-empty, same as -d option
-PYTHONINSPECT    If non-empty, same as -i option
-PYTHONSUPPRESS   If non-empty, same as -s option
-PYTHONUNBUFFERED If non-empty, same as -u option
-PYTHONVERBOSE    If non-empty, same as -v option
-PYTHONCASEOK     If non-empty, ignore case in file/module names (imports)

-  * (list of keywords in std module: keyword)
-  * Illegitimate Tokens (only valid in strings): @ $ ?
-  * A statement must all be on a single line. To break a statement over
-    multiple lines use "\", as with the C preprocessor.
-    Exception: can always break when inside any (), [], or {} pair, or in
-    triple-quoted strings.
-  * More than one statement can appear on a line if they are separated with
-    semicolons (";").
-  * Comments start with "#" and continue to end of line.
-
-Identifiers
-
-        (letter | "_")  (letter | digit | "_")*
-
-  * Python identifiers keywords, attributes, etc. are case-sensitive.
-  * Special forms: _ident (not imported by 'from module import *'); __ident__
-    (system defined name);
-               __ident (class-private name mangling)
-
-Strings
-
-    "a string enclosed by double quotes"
-    'another string delimited by single quotes and with a " inside'
-    '''a string containing embedded newlines and quote (') marks, can be
-    delimited with triple quotes.'''
-    """ may also use 3- double quotes as delimiters """
-    u'a unicode string'   U"Another unicode string"
-    r'a raw string where \ are kept (literalized): handy for regular
-    expressions and windows paths!'
-    R"another raw string"    -- raw strings cannot end with a \
-    ur'a unicode raw string'   UR"another raw unicode"
-
-        Use \ at end of line to continue a string on next line.
-        adjacent strings are concatened, e.g. 'Monty' ' Python' is the same as
-        'Monty Python'.
-        u'hello' + ' world'  --> u'hello world'   (coerced to unicode)
-
-    String Literal Escapes
-
-     \newline  Ignored (escape newline)
-     \\ Backslash (\)        \e Escape (ESC)        \v Vertical Tab (VT)
-     \' Single quote (')     \f Formfeed (FF)       \OOO char with octal value OOO
-     \" Double quote (")     \n Linefeed (LF)
-     \a Bell (BEL)           \r Carriage Return (CR) \xHH  char with hex value HH
-     \b Backspace (BS)       \t Horizontal Tab (TAB)
-     \uHHHH  unicode char with hex value HHHH, can only be used in unicode string
-     \UHHHHHHHH  unicode char with hex value HHHHHHHH, can only be used in unicode string
-     \AnyOtherChar is left as-is
-
-  * NUL byte (\000) is NOT an end-of-string marker; NULs may be embedded in
-    strings.
-  * Strings (and tuples) are immutable: they cannot be modified.
-
-Numbers
-
-    Decimal integer: 1234, 1234567890546378940L        (or l)
-    Octal integer: 0177, 0177777777777777777 (begin with a 0)
-    Hex integer: 0xFF, 0XFFFFffffFFFFFFFFFF (begin with 0x or 0X)
-    Long integer (unlimited precision): 1234567890123456
-    Float (double precision): 3.14e-10, .001, 10., 1E3
-    Complex: 1J, 2+3J, 4+5j (ends with J or j, + separates (float) real and
-    imaginary parts)
-
-Sequences
-
-  * String of length 0, 1, 2 (see above)
-    '', '1', "12", 'hello\n'
-  * Tuple of length 0, 1, 2, etc:
-    () (1,) (1,2)     # parentheses are optional if len > 0
-  * List of length 0, 1, 2, etc:
-    [] [1] [1,2]
-
-Indexing is 0-based. Negative indices (usually) mean count backwards from end
-of sequence.
-
-Sequence slicing [starting-at-index : but-less-than-index]. Start defaults to
-'0'; End defaults to 'sequence-length'.
-
-a = (0,1,2,3,4,5,6,7)
-    a[3] ==> 3
-    a[-1] ==> 7
-    a[2:4] ==> (2, 3)
-    a[1:] ==> (1, 2, 3, 4, 5, 6, 7)
-    a[:3] ==> (0, 1, 2)
-    a[:] ==> (0,1,2,3,4,5,6,7)  # makes a copy of the sequence.
-
-Dictionaries (Mappings)
-
-    {}                              # Zero length empty dictionary
-    {1 : 'first'}                   # Dictionary with one (key, value) pair
-    {1 : 'first',  'next': 'second'}
-    dict([('one',1),('two',2)])     # Construct a dict from an item list
-    dict('one'=1, 'two'=2)          # Construct a dict using keyword args
-    dict.fromkeys(['one', 'keys'])  # Construct a dict from a sequence

-
-Alternate names are defined in module operator (e.g. __add__ and add for +)
-Most operators are overridable.
-
-Many binary operators also support augmented assignment:
-        x += 1                            # Same as x = x + 1
-
-
-Basic Types and Their Operations
-
-Comparisons (defined between *any* types)
-
-               Comparisons
-Comparison         Meaning          Notes
-<          strictly less than        (1)
-<=         less than or equal to
->          strictly greater than
->=         greater than or equal to
-==         equal to
-!=         not equal to
-is         object identity           (2)
-is not     negated object identity   (2)
-
-Notes :
-    Comparison behavior can be overridden for a given class by defining special
-method __cmp__.
-    The above comparisons return True or False which are of type bool
-(a subclass of int) and behave exactly as 1 or 0 except for their type and
-that they print as True or False instead of 1 or 0.
-    (1) X < Y < Z < W has expected meaning, unlike C
-    (2) Compare object identities (i.e. id(object)), not object values.
-
-Boolean values and operators
-
-                         Boolean values and operators
-              Value or Operator                         Returns           Notes
-None, numeric zeros, empty sequences and      False
-mappings
-all other values                              True
-not x                                         True if x is False, else
-                                              True
-x or y                                        if x is False then y, else   (1)

-    (2) The slice of s from i to j is defined as the sequence of items with
-index k such that i <= k < j.
-          If i or j is greater than len(s), use len(s). If i is omitted, use
-len(s). If i is greater than or

-
-Notes :
-    (1) raise a ValueError exception when x is not found in s (i.e. out of
-range).
-     (2) The sort() method takes an optional argument specifying a comparison
-fct of 2 arguments (list items) which should
-          return -1, 0, or 1 depending on whether the 1st argument is
-considered smaller than, equal to, or larger than the 2nd
-          argument. Note that this slows the sorting process down considerably.
-     (3) The sort() and reverse() methods modify the list in place for economy
-of space when sorting or reversing a large list.
-           They don't return the sorted or reversed list to remind you of this
-side effect.
-     (4) [New 1.5.2] The optional  argument i defaults to -1, so that by default the last
-item is removed and returned.

-    (11) Line breaks are not included in the resulting list unless keepends is
-given and true.
-    (12) table must be a string of length 256. All characters occurring in the
-optional argument deletechars are removed prior to translation.

-String formatting with the % operator
-
-formatString % args--> evaluates to a string
-
-  * formatString uses C printf format codes : %, c, s, i, d, u, o, x, X, e, E,
-    f, g, G, r (details below).
-  * Width and precision may be a * to specify that an integer argument gives
-    the actual width or precision.
-  * The flag characters -, +, blank, # and 0 are understood. (details below)
-  * %s will convert any type argument to string (uses str() function)
-  * args may be a single arg or a tuple of args
-
-        '%s has %03d quote types.' % ('Python', 2)  # => 'Python has 002 quote types.'
-
-  * Right-hand-side can also be a mapping:
-
-        a = '%(lang)s has %(c)03d quote types.' % {'c':2, 'lang':'Python}
-(vars() function very handy to use on right-hand-side.)
-
-                                 Format codes

-G          Same as "E" if exponent is greater than -4 or less than precision,
-           "F" otherwise.
-c          Single character (accepts integer or single character string).
-r          String (converts any python object using repr()).
-s          String (converts any python object using str()).
-%          No argument is converted, results in a "%" character in the result.
-           (The complete specification is %%.)
-
-                          Conversion flag characters
-Flag                                  Meaning
-#    The value conversion will use the ``alternate form''.
-0    The conversion will be zero padded.
--    The converted value is left adjusted (overrides "-").
-     (a space) A blank should be left before a positive number (or empty
-     string) produced by a signed conversion.
-+    A sign character ("+" or "-") will precede the conversion (overrides a
-     "space" flag).

-                       "callable()"       <=>  "callable(1, 2)"
-                       "callable(10)"     <=>  "callable(10, 2)"
-                       "callable(p2=99)"  <=>  "callable(1, 99)"
-                       *args is a tuple of positional arguments.
-                       **kw is a dictionary of keyword arguments.

-    a = b    Basic assignment - assign object b to label a  (1)
-    a += b   Roughly equivalent to a = a + b                (2)
-    a -= b   Roughly equivalent to a = a - b                (2)
-    a *= b   Roughly equivalent to a = a * b                (2)
-    a /= b   Roughly equivalent to a = a / b                (2)
-    a %= b   Roughly equivalent to a = a % b                (2)
-    a **= b  Roughly equivalent to a = a ** b               (2)
-    a &= b   Roughly equivalent to a = a & b                (2)
-    a |= b   Roughly equivalent to a = a | b                (2)

-    Control Flow
-
-    if condition: suite
-    [elif condition: suite]*
-    [else: suite]   -- usual if/else_if/else statement
-    while condition: suite
-    [else: suite]
-                    -- usual while statement. "else" suite is executed
-                       after loop exits, unless the loop is exited with
-                       "break"
-    for element in sequence: suite

-    return [result] -- Exits from function (or method) and returns result (use a tuple to
-                       return more than one value). If no result given, then returns None.
-    yield result    -- Freezes the execution frame of a generator and returns the result
-                       to the iterator's .__next__() method.  Upon the next call to __next__(),
-                       resumes execution at the frozen point with all of the local variables
-                       still intact.
-
-    Exception Statements
-
-    assert expr[, message]
-                    -- expr is evaluated. if false, raises exception AssertionError
-                       with message. Inhibited if __debug__ is 0.
-    try: suite1
-    [except [exception [, value]: suite2]+
-    [else: suite3]
-                    -- statements in suite1 are executed. If an exception occurs, look
-                       in "except" clauses for matching <exception>. If matches or bare
-                       "except" execute suite of that clause. If no exception happens
-                       suite in "else" clause is executed after suite1.
-                       If exception has a value, it is put in value.
-                       exception can also be tuple of exceptions, e.g.
-                       "except (KeyError, NameError), val: print val"
-    try: suite1
-    finally: suite2
-                    -- statements in suite1 are executed. If no
-                       exception, execute suite2 (even if suite1 is
-                       exited with a "return", "break" or "continue"
-                       statement). If exception did occur, executes
-                       suite2 and then immediately reraises exception.
-    raise exception [,value [, traceback]]
-                    -- raises exception with optional value
-                       value. Arg traceback specifies a traceback object to
-                       use when printing the exception's backtrace.
-    raise           -- a raise statement without arguments re-raises
-                       the last exception raised in the current function
-An exception is either a string (object) or a class instance.
-  Can create a new one simply by creating a new string:
-
-              my_exception = 'You did something wrong'
-      try:
-                   if bad:
-              raise my_exception, bad
-      except my_exception, value:
-                    print 'Oops', value
-
-Exception classes must be derived from the predefined class: Exception, e.g.:
-            class text_exception(Exception): pass
-            try:
-                if bad:
-                    raise text_exception()
-                    # This is a shorthand for the form
-                    # "raise <class>, <instance>"
-             except Exception:
-                 print 'Oops'
-                 # This will be printed because
-                 # text_exception is a subclass of Exception
-When an error message is printed for an unhandled exception which is a
-class, the class name is printed, then a colon and a space, and
-finally the instance converted to a string using the built-in function
-str().
-All built-in exception classes derives from Exception, itself
-derived from BaseException.

-Name Space Statements
-
-[1.51: On Mac & Windows, the case of module file names must now match the case
-as used
-  in the import statement]
-Packages (>1.5): a package is a name space which maps to a directory including
-                module(s) and the special initialization module '__init__.py'
-                (possibly empty). Packages/dirs can be nested. You address a
-                module's symbol via '[package.[package...]module.symbol's.
-import module1 [as name1] [, module2]*
-                -- imports modules. Members of module must be
-                   referred to by qualifying with [package.]module name:
-                   "import sys; print sys.argv:"
-                   "import package1.subpackage.module; package1.subpackage.module.foo()"
-                   module1 renamed as name1, if supplied.
-from module import name1 [as othername1] [, name2]*
-                -- imports names from module module in current namespace.
-                   "from sys import argv; print argv"
-                   "from package1 import module; module.foo()"
-                   "from package1.module import foo; foo()"
-                   name1 renamed as othername1, if supplied.
-from module import *
-                -- imports all names in module, except those starting with "_";
-                   *to be used sparsely, beware of name clashes* :
-                   "from sys import *; print argv"
-                   "from package.module import *; print x'
-                    NB: "from package import *" only imports the symbols defined
-                    in the package's __init__.py file, not those in the
-                    template modules!
-global name1 [, name2]*
-                -- names are from global scope (usually meaning from module)
-                   rather than local (usually meaning only in function).
-                -- E.g. in fct without "global" statements, assuming
-                   "a" is name that hasn't been used in fct or module
-                   so far:
-                   -Try to read from "a" -> NameError
-                   -Try to write to "a" -> creates "a" local to fcn
-                   -If "a" not defined in fct, but is in module, then
-                       -Try to read from "a", gets value from module
-                       -Try to write to "a", creates "a" local to fct
-                   But note "a[0]=3" starts with search for "a",
-                   will use to global "a" if no local "a".

-Function Definition
-
-def func_id ([param_list]): suite
-                -- Creates a function object & binds it to name func_id.
-
-    param_list ::= [id [, id]*]
-    id ::= value | id = value | *id | **id
-    [Args are passed by value.Thus only args representing a mutable object
-    can be modified (are inout parameters). Use a tuple to return more than
-    one value]
-
-Example:
-        def test (p1, p2 = 1+1, *rest, **keywords):
-            -- Parameters with "=" have default value (v is
-               evaluated when function defined).
-               If list has "*id" then id is assigned a tuple of
-               all remaining args passed to function (like C vararg)
-               If list has "**id" then id is assigned a dictionary of
-               all extra arguments passed as keywords.
-
-Class Definition
-
-class <class_id> [(<super_class1> [,<super_class2>]*)]: <suite>
-        -- Creates a class object and assigns it name <class_id>
-           <suite> may contain local "defs" of class methods and
-           assignments to class attributes.
-Example:
-       class my_class (class1, class_list[3]): ...
-                  Creates a class object inheriting from both "class1" and whatever
-                  class object "class_list[3]" evaluates to. Assigns new
-                  class object to name "my_class".
-        - First arg to class methods is always instance object, called 'self'
-          by convention.
-        - Special method __init__() is called when instance is created.
-        - Special method __del__() called when no more reference to object.
-        - Create instance by "calling" class object, possibly with arg
-          (thus instance=apply(aClassObject, args...) creates an instance!)
-        - In current implementation, can't subclass off built-in
-          classes. But can "wrap" them, see UserDict & UserList modules,
-          and see __getattr__() below.
-Example:
-        class c (c_parent):
-           def __init__(self, name): self.name = name
-           def print_name(self): print "I'm", self.name
-           def call_parent(self): c_parent.print_name(self)
-           instance = c('tom')
-           print instance.name
-           'tom'
-           instance.print_name()
-           "I'm tom"
-        Call parent's super class by accessing parent's method
-        directly and passing "self" explicitly (see "call_parent"
-        in example above).
-        Many other special methods available for implementing
-        arithmetic operators, sequence, mapping indexing, etc.
-
-Documentation Strings
-
-Modules, classes and functions may be documented by placing a string literal by
-itself as the first statement in the suite. The documentation can be retrieved
-by getting the '__doc__' attribute from the module, class or function.
-Example:
-        class C:
-            "A description of C"
-            def __init__(self):
-                "A description of the constructor"
-                # etc.
-Then c.__doc__ == "A description of C".
-Then c.__init__.__doc__ == "A description of the constructor".
-
-Others
-
-lambda [param_list]: returnedExpr
-                -- Creates an anonymous function. returnedExpr must be
-                   an expression, not a statement (e.g., not "if xx:...",
-                   "print xxx", etc.) and thus can't contain newlines.
-                   Used mostly for filter(), map() functions, and GUI callbacks..
-List comprehensions
-result = [expression for item1 in sequence1  [if condition1]
-                        [for item2 in sequence2 ... for itemN in sequenceN]
-                      ]
-is equivalent to:
-result = []
-for item1 in sequence1:
-    for item2 in sequence2:
-    ...
-        for itemN in sequenceN:
-             if (condition1) and furthur conditions:
-                  result.append(expression)

-Standard methods & operators redefinition in classes
-
-Standard methods & operators map to special '__methods__' and thus may be
- redefined (mostly in user-defined classes), e.g.:
-    class x:
-         def __init__(self, v): self.value = v
-         def __add__(self, r): return self.value + r
-    a = x(3) # sort of like calling x.__init__(a, 3)
-    a + 4    # is equivalent to a.__add__(4)
-
-Special methods for any class
-
-(s: self, o: other)

-        DEL      reduce indentation, or delete single character
-Primarily for reindenting existing code:
-        C-c :    guess py-indent-offset from file content; change locally
-        C-u C-c :        ditto, but change globally
-        C-c TAB  reindent region to match its context
-        C-c <    shift region left by py-indent-offset
-        C-c >    shift region right by py-indent-offset

-C-c !   starts a Python interpreter window; this will be used by
-        subsequent C-c C-c or C-c | commands
-C-c C-w runs PyChecker
-
-VARIABLES
-py-indent-offset        indentation increment

-
-(Not revised, possibly not up to date, see 1.5.2 Library Ref section 9.1; in 1.5.2, you may also use debugger integrated in IDLE)
-
-Accessing
-
-import pdb      (it's a module written in Python)
-        -- defines functions :
-           run(statement[,globals[, locals]])
-                        -- execute statement string under debugger control, with optional
-                           global & local environment.
-           runeval(expression[,globals[, locals]])
-                        -- same as run, but evaluate expression and return value.
-           runcall(function[, argument, ...])
-                        -- run function object with given arg(s)
-           pm()         -- run postmortem on last exception (like debugging a core file)
-           post_mortem(t)
-                        -- run postmortem on traceback object <t>
-
-        -- defines class Pdb :
-           use Pdb to create reusable debugger objects. Object
-           preserves state (i.e. break points) between calls.
-
-        runs until a breakpoint hit, exception, or end of program
-        If exception, variable '__exception__' holds (exception,value).
-
-Commands
-
-h, help
-        brief reminder of commands
-b, break [<arg>]
-        if <arg> numeric, break at line <arg> in current file
-        if <arg> is function object, break on entry to fcn <arg>
-        if no arg, list breakpoints
-cl, clear [<arg>]
-        if <arg> numeric, clear breakpoint at <arg> in current file
-        if no arg, clear all breakpoints after confirmation
-w, where
-        print current call stack
-u, up
-        move up one stack frame (to top-level caller)
-d, down
-        move down one stack frame
-s, step
-        advance one line in the program, stepping into calls
-n, next
-        advance one line, stepping over calls
-r, return
-        continue execution until current function returns
-        (return value is saved in variable "__return__", which
-        can be printed or manipulated from debugger)
-c, continue
-        continue until next breakpoint
-j, jump lineno
-        Set the next line that will be executed
-a, args
-        print args to current function
-rv, retval
-        prints return value from last function that returned
-p, print <arg>
-        prints value of <arg> in current stack frame
-l, list [<first> [, <last>]]
-               List source code for the current file.
-               Without arguments, list 11 lines around the current line
-               or continue the previous listing.
-               With one argument, list 11 lines starting at that line.
-               With two arguments, list the given range;
-               if the second argument is less than the first, it is a count.
-whatis <arg>
-        prints type of <arg>
-!
-        executes rest of line as a Python statement in the current stack frame
-q quit
-        immediately stop execution and leave debugger
-<return>
-        executes last command again
-Any input debugger doesn't recognize as a command is assumed to be a
-Python statement to execute in the current stack frame, the same way
-the exclamation mark ("!") command does.

-Quirks
-
-Breakpoints are stored as filename, line number tuples. If a module is reloaded
-after editing, any remembered breakpoints are likely to be wrong.
-
-Always single-steps through top-most stack frame. That is, "c" acts like "n".

-Maintainers Index
-=================
-
-.. warning::
-
-   This document is out of date and replaced by another version in the
-   developer's guide at http://docs.python.org/devguide/experts
-
-This document has tables that list Python Modules, Tools, Platforms and
-Interest Areas and names for each item that indicate a maintainer or an
-expert in the field.  This list is intended to be used by issue submitters,
-issue triage people, and other issue participants to find people to add to
-the nosy list or to contact directly by email for help and decisions on
-feature requests and bug fixes.  People on this list may be asked to render
-final judgement on a feature or bug.  If no active maintainer is listed for
-a given module, then questionable changes should go to python-dev, while
-any other issues can and should be decided by any committer.
-
-Unless a name is followed by a '*', you should never assign an issue to
-that person, only make them nosy.  Names followed by a '*' may be assigned
-issues involving the module or topic.
-
-The Platform and Interest Area tables list broader fields in which various
-people have expertise.  These people can also be contacted for help,
-opinions, and decisions when issues involve their areas.
-
-If a listed maintainer does not respond to requests for comment for an
-extended period (three weeks or more), they should be marked as inactive
-in this list by placing the word 'inactive' in parenthesis behind their
-tracker id.  They are of course free to remove that inactive mark at
-any time.
-
-Committers should update these tables as their areas of expertise widen.
-New topics may be added to the Interest Area table at will.
-
-The existence of this list is not meant to indicate that these people
-*must* be contacted for decisions; it is, rather, a resource to be used
-by non-committers to find responsible parties, and by committers who do
-not feel qualified to make a decision in a particular context.
-
-See also `PEP 291`_ and `PEP 360`_ for information about certain modules
-with special rules.

-   Template for a setuid program that calls a script.
-
-   The script should be in an unwritable directory and should itself
-   be unwritable.  In fact all parent directories up to the root
-   should be unwritable.  The script must not be setuid, that's what
-   this program is for.
-
-   This is a template program.  You need to fill in the name of the
-   script that must be executed.  This is done by changing the
-   definition of FULL_PATH below.
-
-   There are also some rules that should be adhered to when writing
-   the script itself.
-
-   The first and most important rule is to never, ever trust that the
-   user of the program will behave properly.  Program defensively.
-   Check your arguments for reasonableness.  If the user is allowed to
-   create files, check the names of the files.  If the program depends
-   on argv[0] for the action it should perform, check it.
-
-   Assuming the script is a Bourne shell script, the first line of the
-   script should be
-    #!/bin/sh -
-   The - is important, don't omit it.  If you're using esh, the first
-   line should be
-    #!/usr/local/bin/esh -f
-   and for ksh, the first line should be
-    #!/usr/local/bin/ksh -p
-   The script should then set the variable IFS to the string
-   consisting of <space>, <tab>, and <newline>.  After this (*not*
-   before!), the PATH variable should be set to a reasonable value and
-   exported.  Do not expect the PATH to have a reasonable value, so do
-   not trust the old value of PATH.  You should then set the umask of
-   the program by calling
-    umask 077 # or 022 if you want the files to be readable
-   If you plan to change directories, you should either unset CDPATH
-   or set it to a good value.  Setting CDPATH to just ``.'' (dot) is a
-   good idea.
-   If, for some reason, you want to use csh, the first line should be
-    #!/bin/csh -fb
-   You should then set the path variable to something reasonable,
-   without trusting the inherited path.  Here too, you should set the
-   umask using the command
-    umask 077 # or 022 if you want the files to be readable

+Tue Nov 26 14:12:43 1996  Anthony Green  <green@csk3.cygnus.com>
+
+	* v8.S: Used STACKFRAME define elsewhere. 
+
+	* ffi.c (ffi_prep_args): Zero out space when USING_PURIFY
+	is set.
+	(ffi_prep_cif_machdep): Allocate the correct stack frame 
+	space for functions with < 6 args.
+
+Tue Oct 29 15:08:55 1996  Anthony Green  <green@rtl.cygnus.com>
+
+	* ffi.c (ffi_prep_args): int z is now size_t z.
+
+Mon Oct 14 13:31:24 1996  Anthony Green  <green@rtl.cygnus.com>
+
+	* v8.S (ffi_call_V8): Gordon rewrites this again. It looks
+	great now.
+
+	* ffi.c (ffi_call): The comment about hijacked registers
+	is no longer valid after gordoni hacked v8.S.
+
+        * v8.S (ffi_call_V8): Rewrote with gordoni. Much simpler.
+	
+	* v8.S, ffi.c: ffi_call() had changed to accept more than
+	two args, so v8.S had to change (because it hijacks incoming
+	arg registers).
+
+	* ffi.c: Interface changes based on feedback from Jim Blandy.
+
+Thu Oct 10 17:48:16 1996  Anthony Green  <green@rtl.cygnus.com>
+
+	* ffi.c, v8.S, objects.mak: Created.

-Platform Specific Notes
-=======================
-
-	MIPS - Irix 5.3 & 6.x
-	---------------------
-
-Irix 6.2 and better supports three different calling conventions: o32,
-n32 and n64. Currently, libffi only supports both o32 and n32 under
-Irix 6.x, but only o32 under Irix 5.3. Libffi will automatically be
-configured for whichever calling convention it was built for.
-
-By default, the configure script will try to build libffi with the GNU
-development tools. To build libffi with the SGI development tools, set
-the environment variable CC to either "cc -32" or "cc -n32" before
-running configure under Irix 6.x (depending on whether you want an o32
-or n32 library), or just "cc" for Irix 5.3.
-
-With the n32 calling convention, when returning structures smaller
-than 16 bytes, be sure to provide an RVALUE that is 8 byte aligned.
-Here's one way of forcing this:
-
-	double struct_storage[2];
-	my_small_struct *s = (my_small_struct *) struct_storage;  
-	/* Use s for RVALUE */
-
-If you don't do this you are liable to get spurious bus errors. 
-
-"long long" values are not supported yet.
-
-You must use GNU Make to build libffi on SGI platforms.
-
-
-	PowerPC System V ABI
-	--------------------
+History
+=======
 
-There are two `System V ABI's which libffi implements for PowerPC.
-They differ only in how small structures are returned from functions.
+See the ChangeLog files for details.
 
-In the FFI_SYSV version, structures that are 8 bytes or smaller are
-returned in registers.  This is what GCC does when it is configured
-for solaris, and is what the System V ABI I have (dated September
-1995) says.
+3.0.10 ???-??-??
+        Fix the N64 build on mips-sgi-irix6.5.
+	Testsuite fixes for Tru64 Unix.
+	Enable builds with Microsoft's compiler.
+	Enable x86 builds with Sun's compiler.
 
-In the FFI_GCC_SYSV version, all structures are returned the same way:
-by passing a pointer as the first argument to the function.  This is
-what GCC does when it is configured for linux or a generic sysv
-target.
+3.0.9 Dec-31-09
+        Add AVR32 and win64 ports.  Add ARM softfp support.
+	Many fixes for AIX, Solaris, HP-UX, *BSD.
+	Several PowerPC and x86-64 bug fixes.
+	Build DLL for windows.
 
-EGCS 1.0.1 (and probably other versions of EGCS/GCC) also has a
-inconsistency with the SysV ABI: When a procedure is called with many
-floating-point arguments, some of them get put on the stack.  They are
-all supposed to be stored in double-precision format, even if they are
-only single-precision, but EGCS stores single-precision arguments as
-single-precision anyway.  This causes one test to fail (the `many
-arguments' test).
+3.0.8 Dec-19-08
+        Add *BSD, BeOS, and PA-Linux support.
 
+3.0.7 Nov-11-08
+        Fix for ppc FreeBSD.
+	(thanks to Andreas Tobler)

+3.0.6 Jul-17-08

+	Mark the sh/sh64 stack as non-executable.

+1 What is libffi?
+*****************
+
+Compilers for high level languages generate code that follow certain
+conventions.  These conventions are necessary, in part, for separate
+compilation to work.  One such convention is the "calling convention".
+The calling convention is a set of assumptions made by the compiler
+about where function arguments will be found on entry to a function.  A
+calling convention also specifies where the return value for a function
+is found.  The calling convention is also sometimes called the "ABI" or
+"Application Binary Interface".  
+
+   Some programs may not know at the time of compilation what arguments
+are to be passed to a function.  For instance, an interpreter may be
+told at run-time about the number and types of arguments used to call a
+given function.  `Libffi' can be used in such programs to provide a
+bridge from the interpreter program to compiled code.
+
+   The `libffi' library provides a portable, high level programming
+interface to various calling conventions.  This allows a programmer to
+call any function specified by a call interface description at run time.
+
+   FFI stands for Foreign Function Interface.  A foreign function
+interface is the popular name for the interface that allows code
+written in one language to call code written in another language.  The
+`libffi' library really only provides the lowest, machine dependent
+layer of a fully featured foreign function interface.  A layer must
+exist above `libffi' that handles type conversions for values passed
+between the two languages.

+
+2.1 The Basics
+==============
+
+`Libffi' assumes that you have a pointer to the function you wish to
+call and that you know the number and types of arguments to pass it, as
+well as the return type of the function.
+
+   The first thing you must do is create an `ffi_cif' object that
+matches the signature of the function you wish to call.  This is a
+separate step because it is common to make multiple calls using a
+single `ffi_cif'.  The "cif" in `ffi_cif' stands for Call InterFace.
+To prepare a call interface object, use the function `ffi_prep_cif'.  
+
+ -- Function: ffi_status ffi_prep_cif (ffi_cif *CIF, ffi_abi ABI,
+          unsigned int NARGS, ffi_type *RTYPE, ffi_type **ARGTYPES)
+     This initializes CIF according to the given parameters.
+
+     ABI is the ABI to use; normally `FFI_DEFAULT_ABI' is what you
+     want.  *note Multiple ABIs:: for more information.
+
+     NARGS is the number of arguments that this function accepts.
+     `libffi' does not yet handle varargs functions; see *note Missing
+     Features:: for more information.
+
+     RTYPE is a pointer to an `ffi_type' structure that describes the
+     return type of the function.  *Note Types::.
+
+     ARGTYPES is a vector of `ffi_type' pointers.  ARGTYPES must have
+     NARGS elements.  If NARGS is 0, this argument is ignored.
+
+     `ffi_prep_cif' returns a `libffi' status code, of type
+     `ffi_status'.  This will be either `FFI_OK' if everything worked
+     properly; `FFI_BAD_TYPEDEF' if one of the `ffi_type' objects is
+     incorrect; or `FFI_BAD_ABI' if the ABI parameter is invalid.
+
+   To call a function using an initialized `ffi_cif', use the
+`ffi_call' function:
+
+ -- Function: void ffi_call (ffi_cif *CIF, void *FN, void *RVALUE, void
+          **AVALUES)
+     This calls the function FN according to the description given in
+     CIF.  CIF must have already been prepared using `ffi_prep_cif'.
+
+     RVALUE is a pointer to a chunk of memory that will hold the result
+     of the function call.  This must be large enough to hold the
+     result and must be suitably aligned; it is the caller's
+     responsibility to ensure this.  If CIF declares that the function
+     returns `void' (using `ffi_type_void'), then RVALUE is ignored.
+     If RVALUE is `NULL', then the return value is discarded.
+
+     AVALUES is a vector of `void *' pointers that point to the memory
+     locations holding the argument values for a call.  If CIF declares
+     that the function has no arguments (i.e., NARGS was 0), then
+     AVALUES is ignored.

+
+2.3.1 Primitive Types
+---------------------
+
+`Libffi' provides a number of built-in type descriptors that can be
+used to describe argument and return types:
+
+`ffi_type_void'
+     The type `void'.  This cannot be used for argument types, only for
+     return values.
+
+`ffi_type_uint8'
+     An unsigned, 8-bit integer type.
+
+`ffi_type_sint8'
+     A signed, 8-bit integer type.
+
+`ffi_type_uint16'
+     An unsigned, 16-bit integer type.
+
+`ffi_type_sint16'
+     A signed, 16-bit integer type.
+
+`ffi_type_uint32'
+     An unsigned, 32-bit integer type.
+
+`ffi_type_sint32'
+     A signed, 32-bit integer type.
+
+`ffi_type_uint64'
+     An unsigned, 64-bit integer type.
+
+`ffi_type_sint64'
+     A signed, 64-bit integer type.
+
+`ffi_type_float'
+     The C `float' type.
+
+`ffi_type_double'
+     The C `double' type.
+
+`ffi_type_uchar'
+     The C `unsigned char' type.
+
+`ffi_type_schar'
+     The C `signed char' type.  (Note that there is not an exact
+     equivalent to the C `char' type in `libffi'; ordinarily you should
+     either use `ffi_type_schar' or `ffi_type_uchar' depending on
+     whether `char' is signed.)
+
+`ffi_type_ushort'
+     The C `unsigned short' type.
+
+`ffi_type_sshort'
+     The C `short' type.
+
+`ffi_type_uint'
+     The C `unsigned int' type.
+
+`ffi_type_sint'
+     The C `int' type.
+
+`ffi_type_ulong'
+     The C `unsigned long' type.
+
+`ffi_type_slong'
+     The C `long' type.
+
+`ffi_type_longdouble'
+     On platforms that have a C `long double' type, this is defined.
+     On other platforms, it is not.
+
+`ffi_type_pointer'
+     A generic `void *' pointer.  You should use this for all pointers,
+     regardless of their real type.
+
+   Each of these is of type `ffi_type', so you must take the address
+when passing to `ffi_prep_cif'.
+
+
+File: libffi.info,  Node: Structures,  Next: Type Example,  Prev: Primitive Types,  Up: Types
+
+2.3.2 Structures
+----------------
+
+Although `libffi' has no special support for unions or bit-fields, it
+is perfectly happy passing structures back and forth.  You must first
+describe the structure to `libffi' by creating a new `ffi_type' object
+for it.
+
+ -- ffi_type:
+     The `ffi_type' has the following members:
+    `size_t size'
+          This is set by `libffi'; you should initialize it to zero.
+
+    `unsigned short alignment'
+          This is set by `libffi'; you should initialize it to zero.
+
+    `unsigned short type'
+          For a structure, this should be set to `FFI_TYPE_STRUCT'.
+
+    `ffi_type **elements'
+          This is a `NULL'-terminated array of pointers to `ffi_type'
+          objects.  There is one element per field of the struct.
+
+
+File: libffi.info,  Node: Type Example,  Prev: Structures,  Up: Types
+
+2.3.3 Type Example
+------------------
+
+The following example initializes a `ffi_type' object representing the
+`tm' struct from Linux's `time.h'.
+
+   Here is how the struct is defined:
+
+     struct tm {
+         int tm_sec;
+         int tm_min;
+         int tm_hour;
+         int tm_mday;
+         int tm_mon;
+         int tm_year;
+         int tm_wday;
+         int tm_yday;
+         int tm_isdst;
+         /* Those are for future use. */
+         long int __tm_gmtoff__;
+         __const char *__tm_zone__;
+     };
+
+   Here is the corresponding code to describe this struct to `libffi':
+
+         {
+           ffi_type tm_type;
+           ffi_type *tm_type_elements[12];
+           int i;
+
+           tm_type.size = tm_type.alignment = 0;
+           tm_type.elements = &tm_type_elements;
+
+           for (i = 0; i < 9; i++)
+               tm_type_elements[i] = &ffi_type_sint;
+
+           tm_type_elements[9] = &ffi_type_slong;
+           tm_type_elements[10] = &ffi_type_pointer;
+           tm_type_elements[11] = NULL;
+
+           /* tm_type can now be used to represent tm argument types and
+     	 return types for ffi_prep_cif() */
+         }

+
+2.4 Multiple ABIs
+=================
+
+A given platform may provide multiple different ABIs at once.  For
+instance, the x86 platform has both `stdcall' and `fastcall' functions.
+
+   `libffi' provides some support for this.  However, this is
+necessarily platform-specific.
+
+
+File: libffi.info,  Node: The Closure API,  Next: Closure Example,  Prev: Multiple ABIs,  Up: Using libffi
+
+2.5 The Closure API
+===================
+
+`libffi' also provides a way to write a generic function - a function
+that can accept and decode any combination of arguments.  This can be
+useful when writing an interpreter, or to provide wrappers for
+arbitrary functions.
+
+   This facility is called the "closure API".  Closures are not
+supported on all platforms; you can check the `FFI_CLOSURES' define to
+determine whether they are supported on the current platform.  
+
+   Because closures work by assembling a tiny function at runtime, they
+require special allocation on platforms that have a non-executable
+heap.  Memory management for closures is handled by a pair of functions:
+
+ -- Function: void *ffi_closure_alloc (size_t SIZE, void **CODE)
+     Allocate a chunk of memory holding SIZE bytes.  This returns a
+     pointer to the writable address, and sets *CODE to the
+     corresponding executable address.
+
+     SIZE should be sufficient to hold a `ffi_closure' object.
+
+ -- Function: void ffi_closure_free (void *WRITABLE)
+     Free memory allocated using `ffi_closure_alloc'.  The argument is
+     the writable address that was returned.
+
+   Once you have allocated the memory for a closure, you must construct
+a `ffi_cif' describing the function call.  Finally you can prepare the
+closure function:
+
+ -- Function: ffi_status ffi_prep_closure_loc (ffi_closure *CLOSURE,
+          ffi_cif *CIF, void (*FUN) (ffi_cif *CIF, void *RET, void
+          **ARGS, void *USER_DATA), void *USER_DATA, void *CODELOC)
+     Prepare a closure function.
+
+     CLOSURE is the address of a `ffi_closure' object; this is the
+     writable address returned by `ffi_closure_alloc'.
+
+     CIF is the `ffi_cif' describing the function parameters.
+
+     USER_DATA is an arbitrary datum that is passed, uninterpreted, to
+     your closure function.
+
+     CODELOC is the executable address returned by `ffi_closure_alloc'.
+
+     FUN is the function which will be called when the closure is
+     invoked.  It is called with the arguments:
+    CIF
+          The `ffi_cif' passed to `ffi_prep_closure_loc'.
+
+    RET
+          A pointer to the memory used for the function's return value.
+          FUN must fill this, unless the function is declared as
+          returning `void'.
+
+    ARGS
+          A vector of pointers to memory holding the arguments to the
+          function.
+
+    USER_DATA
+          The same USER_DATA that was passed to `ffi_prep_closure_loc'.
+
+     `ffi_prep_closure_loc' will return `FFI_OK' if everything went ok,
+     and something else on error.
+
+     After calling `ffi_prep_closure_loc', you can cast CODELOC to the
+     appropriate pointer-to-function type.
+
+   You may see old code referring to `ffi_prep_closure'.  This function
+is deprecated, as it cannot handle the need for separate writable and
+executable addresses.

+2.6 Closure Example
+===================
+
+A trivial example that creates a new `puts' by binding `fputs' with
+`stdin'.
+
+     #include <stdio.h>
+     #include <ffi.h>
+
+     /* Acts like puts with the file given at time of enclosure. */
+     void puts_binding(ffi_cif *cif, unsigned int *ret, void* args[],
+                       FILE *stream)
+     {
+       *ret = fputs(*(char **)args[0], stream);
+     }
+
+     int main()
+     {
+       ffi_cif cif;
+       ffi_type *args[1];
+       ffi_closure *closure;
+
+       int (*bound_puts)(char *);
+       int rc;
+
+       /* Allocate closure and bound_puts */
+       closure = ffi_closure_alloc(sizeof(ffi_closure), &bound_puts);
+
+       if (closure)
+         {
+           /* Initialize the argument info vectors */
+           args[0] = &ffi_type_pointer;
+
+           /* Initialize the cif */
+           if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1,
+                            &ffi_type_uint, args) == FFI_OK)
+             {
+               /* Initialize the closure, setting stream to stdout */
+               if (ffi_prep_closure_loc(closure, &cif, puts_binding,
+                                        stdout, bound_puts) == FFI_OK)
+                 {
+                   rc = bound_puts("Hello World!");
+                   /* rc now holds the result of the call to fputs */
+                 }
+             }
+         }
+
+       /* Deallocate both closure, and bound_puts */
+       ffi_closure_free(closure);
+
+       return 0;
+     }

+3 Missing Features
+******************
+
+`libffi' is missing a few features.  We welcome patches to add support
+for these.
+
+   * There is no support for calling varargs functions.  This may work
+     on some platforms, depending on how the ABI is defined, but it is
+     not reliable.
+
+   * There is no support for bit fields in structures.
+
+   * The closure API is
+
+   * The "raw" API is undocumented.

+@chapter What is libffi?
+
+Compilers for high level languages generate code that follow certain
+conventions.  These conventions are necessary, in part, for separate
+compilation to work.  One such convention is the @dfn{calling
+convention}.  The calling convention is a set of assumptions made by
+the compiler about where function arguments will be found on entry to
+a function.  A calling convention also specifies where the return
+value for a function is found.  The calling convention is also
+sometimes called the @dfn{ABI} or @dfn{Application Binary Interface}.
+@cindex calling convention
+@cindex ABI
+@cindex Application Binary Interface
+
+Some programs may not know at the time of compilation what arguments
+are to be passed to a function.  For instance, an interpreter may be
+told at run-time about the number and types of arguments used to call
+a given function.  @samp{Libffi} can be used in such programs to
+provide a bridge from the interpreter program to compiled code.
+
+The @samp{libffi} library provides a portable, high level programming
+interface to various calling conventions.  This allows a programmer to
+call any function specified by a call interface description at run
+time.
+

+@section The Basics
+
+@samp{Libffi} assumes that you have a pointer to the function you wish
+to call and that you know the number and types of arguments to pass
+it, as well as the return type of the function.
+
+The first thing you must do is create an @code{ffi_cif} object that
+matches the signature of the function you wish to call.  This is a
+separate step because it is common to make multiple calls using a
+single @code{ffi_cif}.  The @dfn{cif} in @code{ffi_cif} stands for
+Call InterFace.  To prepare a call interface object, use the function
+@code{ffi_prep_cif}.
+@cindex cif
+
+@findex ffi_prep_cif
+@defun ffi_status ffi_prep_cif (ffi_cif *@var{cif}, ffi_abi @var{abi}, unsigned int @var{nargs}, ffi_type *@var{rtype}, ffi_type **@var{argtypes})
+This initializes @var{cif} according to the given parameters.
+
+@var{abi} is the ABI to use; normally @code{FFI_DEFAULT_ABI} is what
+you want.  @ref{Multiple ABIs} for more information.
+
+@var{nargs} is the number of arguments that this function accepts.
+@samp{libffi} does not yet handle varargs functions; see @ref{Missing
+Features} for more information.
+
+@var{rtype} is a pointer to an @code{ffi_type} structure that
+describes the return type of the function.  @xref{Types}.
+
+@var{argtypes} is a vector of @code{ffi_type} pointers.
+@var{argtypes} must have @var{nargs} elements.  If @var{nargs} is 0,
+this argument is ignored.
+
+@code{ffi_prep_cif} returns a @code{libffi} status code, of type
+@code{ffi_status}.  This will be either @code{FFI_OK} if everything
+worked properly; @code{FFI_BAD_TYPEDEF} if one of the @code{ffi_type}
+objects is incorrect; or @code{FFI_BAD_ABI} if the @var{abi} parameter
+is invalid.
+@end defun
+
+
+To call a function using an initialized @code{ffi_cif}, use the
+@code{ffi_call} function:
+
+@findex ffi_call
+@defun void ffi_call (ffi_cif *@var{cif}, void *@var{fn}, void *@var{rvalue}, void **@var{avalues})
+This calls the function @var{fn} according to the description given in
+@var{cif}.  @var{cif} must have already been prepared using
+@code{ffi_prep_cif}.
+
+@var{rvalue} is a pointer to a chunk of memory that will hold the
+result of the function call.  This must be large enough to hold the
+result and must be suitably aligned; it is the caller's responsibility
+to ensure this.  If @var{cif} declares that the function returns
+@code{void} (using @code{ffi_type_void}), then @var{rvalue} is
+ignored.  If @var{rvalue} is @samp{NULL}, then the return value is
+discarded.
+
+@var{avalues} is a vector of @code{void *} pointers that point to the
+memory locations holding the argument values for a call.  If @var{cif}
+declares that the function has no arguments (i.e., @var{nargs} was 0),
+then @var{avalues} is ignored.
+@end defun
+
+
+@node Simple Example
+@section Simple Example
+
+Here is a trivial example that calls @code{puts} a few times.
+

+      
+      /* values holds a pointer to the function's arg, so to

+@subsection Primitive Types
+
+@code{Libffi} provides a number of built-in type descriptors that can
+be used to describe argument and return types:
+
+@table @code
+@item ffi_type_void
+@tindex ffi_type_void
+The type @code{void}.  This cannot be used for argument types, only
+for return values.
+
+@item ffi_type_uint8
+@tindex ffi_type_uint8
+An unsigned, 8-bit integer type.
+
+@item ffi_type_sint8
+@tindex ffi_type_sint8
+A signed, 8-bit integer type.
+
+@item ffi_type_uint16
+@tindex ffi_type_uint16
+An unsigned, 16-bit integer type.
+
+@item ffi_type_sint16
+@tindex ffi_type_sint16
+A signed, 16-bit integer type.
+
+@item ffi_type_uint32
+@tindex ffi_type_uint32
+An unsigned, 32-bit integer type.
+
+@item ffi_type_sint32
+@tindex ffi_type_sint32
+A signed, 32-bit integer type.
+
+@item ffi_type_uint64
+@tindex ffi_type_uint64
+An unsigned, 64-bit integer type.
+
+@item ffi_type_sint64
+@tindex ffi_type_sint64
+A signed, 64-bit integer type.
+
+@item ffi_type_float
+@tindex ffi_type_float
+The C @code{float} type.
+
+@item ffi_type_double
+@tindex ffi_type_double
+The C @code{double} type.
+
+@item ffi_type_uchar
+@tindex ffi_type_uchar
+The C @code{unsigned char} type.
+
+@item ffi_type_schar
+@tindex ffi_type_schar
+The C @code{signed char} type.  (Note that there is not an exact
+equivalent to the C @code{char} type in @code{libffi}; ordinarily you
+should either use @code{ffi_type_schar} or @code{ffi_type_uchar}
+depending on whether @code{char} is signed.)
+
+@item ffi_type_ushort
+@tindex ffi_type_ushort
+The C @code{unsigned short} type.
+
+@item ffi_type_sshort
+@tindex ffi_type_sshort
+The C @code{short} type.
+
+@item ffi_type_uint
+@tindex ffi_type_uint
+The C @code{unsigned int} type.
+
+@item ffi_type_sint
+@tindex ffi_type_sint
+The C @code{int} type.
+
+@item ffi_type_ulong
+@tindex ffi_type_ulong
+The C @code{unsigned long} type.
+
+@item ffi_type_slong
+@tindex ffi_type_slong
+The C @code{long} type.
+
+@item ffi_type_longdouble
+@tindex ffi_type_longdouble
+On platforms that have a C @code{long double} type, this is defined.
+On other platforms, it is not.
+
+@item ffi_type_pointer
+@tindex ffi_type_pointer
+A generic @code{void *} pointer.  You should use this for all
+pointers, regardless of their real type.
+@end table
+
+Each of these is of type @code{ffi_type}, so you must take the address
+when passing to @code{ffi_prep_cif}.
+
+
+@node Structures
+@subsection Structures
+
+Although @samp{libffi} has no special support for unions or
+bit-fields, it is perfectly happy passing structures back and forth.
+You must first describe the structure to @samp{libffi} by creating a
+new @code{ffi_type} object for it.
+
+@tindex ffi_type
+@deftp ffi_type
+The @code{ffi_type} has the following members:
+@table @code
+@item size_t size
+This is set by @code{libffi}; you should initialize it to zero.
+
+@item unsigned short alignment
+This is set by @code{libffi}; you should initialize it to zero.
+
+@item unsigned short type
+For a structure, this should be set to @code{FFI_TYPE_STRUCT}.
+
+@item ffi_type **elements
+This is a @samp{NULL}-terminated array of pointers to @code{ffi_type}
+objects.  There is one element per field of the struct.
+@end table
+@end deftp
+
+
+@node Type Example
+@subsection Type Example
+
+The following example initializes a @code{ffi_type} object
+representing the @code{tm} struct from Linux's @file{time.h}.
+
+Here is how the struct is defined:
+
+@example
+struct tm @{
+    int tm_sec;
+    int tm_min;
+    int tm_hour;
+    int tm_mday;
+    int tm_mon;
+    int tm_year;
+    int tm_wday;
+    int tm_yday;
+    int tm_isdst;
+    /* Those are for future use. */
+    long int __tm_gmtoff__;
+    __const char *__tm_zone__;
+@};
+@end example
+
+Here is the corresponding code to describe this struct to
+@code{libffi}:
+
+@example
+    @{
+      ffi_type tm_type;
+      ffi_type *tm_type_elements[12];
+      int i;
+
+      tm_type.size = tm_type.alignment = 0;
+      tm_type.elements = &tm_type_elements;
+    
+      for (i = 0; i < 9; i++)
+          tm_type_elements[i] = &ffi_type_sint;
+
+      tm_type_elements[9] = &ffi_type_slong;
+      tm_type_elements[10] = &ffi_type_pointer;
+      tm_type_elements[11] = NULL;
+
+      /* tm_type can now be used to represent tm argument types and
+	 return types for ffi_prep_cif() */

+@node Multiple ABIs
+@section Multiple ABIs
+
+A given platform may provide multiple different ABIs at once.  For
+instance, the x86 platform has both @samp{stdcall} and @samp{fastcall}
+functions.
+
+@code{libffi} provides some support for this.  However, this is
+necessarily platform-specific.
+
+@c FIXME: document the platforms
+
+@node The Closure API
+@section The Closure API
+
+@code{libffi} also provides a way to write a generic function -- a
+function that can accept and decode any combination of arguments.
+This can be useful when writing an interpreter, or to provide wrappers
+for arbitrary functions.
+
+This facility is called the @dfn{closure API}.  Closures are not
+supported on all platforms; you can check the @code{FFI_CLOSURES}
+define to determine whether they are supported on the current
+platform.
+@cindex closures
+@cindex closure API
+@findex FFI_CLOSURES
+
+Because closures work by assembling a tiny function at runtime, they
+require special allocation on platforms that have a non-executable
+heap.  Memory management for closures is handled by a pair of
+functions:
+
+@findex ffi_closure_alloca
+@defun void *ffi_closure_alloc (size_t @var{size}, void **@var{code})
+Allocate a chunk of memory holding @var{size} bytes.  This returns a
+pointer to the writable address, and sets *@var{code} to the
+corresponding executable address.
+
+@var{size} should be sufficient to hold a @code{ffi_closure} object.
+@end defun
+
+@findex ffi_closure_free
+@defun void ffi_closure_free (void *@var{writable})
+Free memory allocated using @code{ffi_closure_alloc}.  The argument is
+the writable address that was returned.
+@end defun
+
+
+Once you have allocated the memory for a closure, you must construct a
+@code{ffi_cif} describing the function call.  Finally you can prepare
+the closure function:
+
+@findex ffi_prep_closure_loc
+@defun ffi_status ffi_prep_closure_loc (ffi_closure *@var{closure}, ffi_cif *@var{cif}, void (*@var{fun}) (ffi_cif *@var{cif}, void *@var{ret}, void **@var{args}, void *@var{user_data}), void *@var{user_data}, void *@var{codeloc})
+Prepare a closure function.
+
+@var{closure} is the address of a @code{ffi_closure} object; this is
+the writable address returned by @code{ffi_closure_alloc}.
+
+@var{cif} is the @code{ffi_cif} describing the function parameters.
+
+@var{user_data} is an arbitrary datum that is passed, uninterpreted,
+to your closure function.
+
+@var{codeloc} is the executable address returned by
+@code{ffi_closure_alloc}.
+
+@var{fun} is the function which will be called when the closure is
+invoked.  It is called with the arguments:
+@table @var
+@item cif
+The @code{ffi_cif} passed to @code{ffi_prep_closure_loc}.
+
+@item ret
+A pointer to the memory used for the function's return value.
+@var{fun} must fill this, unless the function is declared as returning
+@code{void}.
+@c FIXME: is this NULL for void-returning functions?
+
+@item args
+A vector of pointers to memory holding the arguments to the function.
+
+@item user_data
+The same @var{user_data} that was passed to
+@code{ffi_prep_closure_loc}.
+@end table
+
+@code{ffi_prep_closure_loc} will return @code{FFI_OK} if everything
+went ok, and something else on error.
+@c FIXME: what?
+
+After calling @code{ffi_prep_closure_loc}, you can cast @var{codeloc}
+to the appropriate pointer-to-function type.
+@end defun
+
+You may see old code referring to @code{ffi_prep_closure}.  This
+function is deprecated, as it cannot handle the need for separate
+writable and executable addresses.
+

+#
+# 3. If the library source code has changed at all since the last
+#    update, then increment revision (`c:r:a' becomes `c:r+1:a').
+#
+# 4. If any interfaces have been added, removed, or changed since the

+.Sh DESCRIPTION
+The
+.Nm ffi_call
+function provides a simple mechanism for invoking a function without
+requiring knowledge of the function's interface at compile time.
+.Fa fn
+is called with the values retrieved from the pointers in the
+.Fa avalue
+array. The return value from
+.Fa fn
+is placed in storage pointed to by
+.Fa rvalue .
+.Fa cif
+contains information describing the data types, sizes and alignments of the
+arguments to and return value from
+.Fa fn ,
+and must be initialized with
+.Nm ffi_prep_cif
+before it is used with
+.Nm ffi_call .
+.Pp
+.Fa rvalue
+must point to storage that is sizeof(ffi_arg) or larger for non-floating point
+types. For smaller-sized return value types, the
+.Nm ffi_arg
+or
+.Nm ffi_sarg
+integral type must be used to hold
+the return value.
+.Sh EXAMPLES

+  This is a version (aka dlmalloc) of malloc/free/realloc written by
+  Doug Lea and released to the public domain, as explained at
+  http://creativecommons.org/licenses/publicdomain.  Send questions,
+  comments, complaints, performance data, etc to dl@cs.oswego.edu
+
+* Version 2.8.3 Thu Sep 22 11:16:15 2005  Doug Lea  (dl at gee)
+
+   Note: There may be an updated version of this malloc obtainable at
+           ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+         Check before installing!
+
+* Quickstart
+
+  This library is all in one file to simplify the most common usage:
+  ftp it, compile it (-O3), and link it into another program. All of
+  the compile-time options default to reasonable values for use on
+  most platforms.  You might later want to step through various
+  compile-time and dynamic tuning options.
+
+  For convenience, an include file for code using this malloc is at:
+     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h
+  You don't really need this .h file unless you call functions not
+  defined in your system include files.  The .h file contains only the
+  excerpts from this file needed for using this malloc on ANSI C/C++
+  systems, so long as you haven't changed compile-time options about
+  naming and tuning parameters.  If you do, then you can create your
+  own malloc.h that does include all settings by cutting at the point
+  indicated below. Note that you may already by default be using a C
+  library containing a malloc that is based on some version of this
+  malloc (for example in linux). You might still want to use the one
+  in this file to customize settings or to avoid overheads associated
+  with library versions.
+
+* Vital statistics:
+
+  Supported pointer/size_t representation:       4 or 8 bytes
+       size_t MUST be an unsigned type of the same width as
+       pointers. (If you are using an ancient system that declares
+       size_t as a signed type, or need it to be a different width
+       than pointers, you can use a previous release of this malloc
+       (e.g. 2.7.2) supporting these.)
+
+  Alignment:                                     8 bytes (default)
+       This suffices for nearly all current machines and C compilers.
+       However, you can define MALLOC_ALIGNMENT to be wider than this
+       if necessary (up to 128bytes), at the expense of using more space.
+
+  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
+                                          8 or 16 bytes (if 8byte sizes)
+       Each malloced chunk has a hidden word of overhead holding size
+       and status information, and additional cross-check word
+       if FOOTERS is defined.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
+                          8-byte ptrs:  32 bytes    (including overhead)
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+       The maximum overhead wastage (i.e., number of extra bytes
+       allocated than were requested in malloc) is less than or equal
+       to the minimum size, except for requests >= mmap_threshold that
+       are serviced via mmap(), where the worst case wastage is about
+       32 bytes plus the remainder from a system page (the minimal
+       mmap unit); typically 4096 or 8192 bytes.
+
+  Security: static-safe; optionally more or less
+       The "security" of malloc refers to the ability of malicious
+       code to accentuate the effects of errors (for example, freeing
+       space that is not currently malloc'ed or overwriting past the
+       ends of chunks) in code that calls malloc.  This malloc
+       guarantees not to modify any memory locations below the base of
+       heap, i.e., static variables, even in the presence of usage
+       errors.  The routines additionally detect most improper frees
+       and reallocs.  All this holds as long as the static bookkeeping
+       for malloc itself is not corrupted by some other means.  This
+       is only one aspect of security -- these checks do not, and
+       cannot, detect all possible programming errors.
+
+       If FOOTERS is defined nonzero, then each allocated chunk
+       carries an additional check word to verify that it was malloced
+       from its space.  These check words are the same within each
+       execution of a program using malloc, but differ across
+       executions, so externally crafted fake chunks cannot be
+       freed. This improves security by rejecting frees/reallocs that
+       could corrupt heap memory, in addition to the checks preventing
+       writes to statics that are always on.  This may further improve
+       security at the expense of time and space overhead.  (Note that
+       FOOTERS may also be worth using with MSPACES.)
+
+       By default detected errors cause the program to abort (calling
+       "abort()"). You can override this to instead proceed past
+       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
+       has no effect, and a malloc that encounters a bad address
+       caused by user overwrites will ignore the bad address by
+       dropping pointers and indices to all known memory. This may
+       be appropriate for programs that should continue if at all
+       possible in the face of programming errors, although they may
+       run out of memory because dropped memory is never reclaimed.
+
+       If you don't like either of these options, you can define
+       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+       else. And if if you are sure that your program using malloc has
+       no errors or vulnerabilities, you can define INSECURE to 1,
+       which might (or might not) provide a small performance improvement.
+
+  Thread-safety: NOT thread-safe unless USE_LOCKS defined
+       When USE_LOCKS is defined, each public call to malloc, free,
+       etc is surrounded with either a pthread mutex or a win32
+       spinlock (depending on WIN32). This is not especially fast, and
+       can be a major bottleneck.  It is designed only to provide
+       minimal protection in concurrent environments, and to provide a
+       basis for extensions.  If you are using malloc in a concurrent
+       program, consider instead using ptmalloc, which is derived from
+       a version of this malloc. (See http://www.malloc.de).
+
+  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+       This malloc can use unix sbrk or any emulation (invoked using
+       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+       memory.  On most unix systems, it tends to work best if both
+       MORECORE and MMAP are enabled.  On Win32, it uses emulations
+       based on VirtualAlloc. It also uses common C library functions
+       like memset.
+
+  Compliance: I believe it is compliant with the Single Unix Specification
+       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+       others as well.
+
+* Overview of algorithms
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and
+  tunable.  Consistent balance across these factors results in a good
+  general-purpose allocator for malloc-intensive programs.
+
+  In most ways, this malloc is a best-fit allocator. Generally, it
+  chooses the best-fitting existing chunk for a request, with ties
+  broken in approximately least-recently-used order. (This strategy
+  normally maintains low fragmentation.) However, for requests less
+  than 256bytes, it deviates from best-fit when there is not an
+  exactly fitting available chunk by preferring to use space adjacent
+  to that used for the previous small request, as well as by breaking
+  ties in approximately most-recently-used order. (These enhance
+  locality of series of small allocations.)  And for very large requests
+  (>= 256Kb by default), it relies on system memory mapping
+  facilities, if supported.  (This helps avoid carrying around and
+  possibly fragmenting memory used only for large chunks.)
+
+  All operations (except malloc_stats and mallinfo) have execution
+  times that are bounded by a constant factor of the number of bits in
+  a size_t, not counting any clearing in calloc or copying in realloc,
+  or actions surrounding MORECORE and MMAP that have times
+  proportional to the number of non-contiguous regions returned by
+  system allocation routines, which is often just 1.
+
+  The implementation is not very modular and seriously overuses
+  macros. Perhaps someday all C compilers will do as good a job
+  inlining modular code as can now be done by brute-force expansion,
+  but now, enough of them seem not to.
+
+  Some compilers issue a lot of warnings about code that is
+  dead/unreachable only on some platforms, and also about intentional
+  uses of negation on unsigned types. All known cases of each can be
+  ignored.
+
+  For a longer but out of date high-level description, see
+     http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+  If MSPACES is defined, then in addition to malloc, free, etc.,
+  this file also defines mspace_malloc, mspace_free, etc. These
+  are versions of malloc routines that take an "mspace" argument
+  obtained using create_mspace, to control all internal bookkeeping.
+  If ONLY_MSPACES is defined, only these versions are compiled.
+  So if you would like to use this allocator for only some allocations,
+  and your system malloc for others, you can compile with
+  ONLY_MSPACES and then do something like...
+    static mspace mymspace = create_mspace(0,0); // for example
+    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
+
+  (Note: If you only need one instance of an mspace, you can instead
+  use "USE_DL_PREFIX" to relabel the global malloc.)
+
+  You can similarly create thread-local allocators by storing
+  mspaces as thread-locals. For example:
+    static __thread mspace tlms = 0;
+    void*  tlmalloc(size_t bytes) {
+      if (tlms == 0) tlms = create_mspace(0, 0);
+      return mspace_malloc(tlms, bytes);
+    }
+    void  tlfree(void* mem) { mspace_free(tlms, mem); }
+
+  Unless FOOTERS is defined, each mspace is completely independent.
+  You cannot allocate from one and free to another (although
+  conformance is only weakly checked, so usage errors are not always
+  caught). If FOOTERS is defined, then each chunk carries around a tag
+  indicating its originating mspace, and frees are directed to their
+  originating spaces.
+
+ -------------------------  Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix.
+
+MALLOC_ALIGNMENT         default: (size_t)8
+  Controls the minimum alignment for malloc'ed chunks.  It must be a
+  power of two and at least 8, even on machines for which smaller
+  alignments would suffice. It may be defined as larger than this
+  though. Note however that code and data structures are optimized for
+  the case of 8-byte alignment.
+
+MSPACES                  default: 0 (false)
+  If true, compile in support for independent allocation spaces.
+  This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES             default: 0 (false)
+  If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS                default: 0 (false)
+  Causes each call to each public routine to be surrounded with
+  pthread or WIN32 mutex lock/unlock. (If set true, this can be
+  overridden on a per-mspace basis for mspace versions.)
+
+FOOTERS                  default: 0
+  If true, provide extra checking and dispatching by placing
+  information in the footers of allocated chunks. This adds
+  space and time overhead.
+
+INSECURE                 default: 0
+  If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX            default: NOT defined
+  Causes compiler to prefix all public routines with the string 'dl'.
+  This can be useful when you only want to use this malloc in one part
+  of a program, using your regular system malloc elsewhere.
+
+ABORT                    default: defined as abort()
+  Defines how to abort on failed checks.  On most systems, a failed
+  check cannot die with an "assert" or even print an informative
+  message, because the underlying print routines in turn call malloc,
+  which will fail again.  Generally, the best policy is to simply call
+  abort(). It's not very useful to do more than this because many
+  errors due to overwriting will show up as address faults (null, odd
+  addresses etc) rather than malloc-triggered checks, so will also
+  abort.  Also, most compilers know that abort() does not return, so
+  can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR           default: defined as 0 (false)
+  Controls whether detected bad addresses cause them to bypassed
+  rather than aborting. If set, detected bad arguments to free and
+  realloc are ignored. And all bookkeeping information is zeroed out
+  upon a detected overwrite of freed heap space, thus losing the
+  ability to ever return it from malloc again, but enabling the
+  application to proceed. If PROCEED_ON_ERROR is defined, the
+  static variable malloc_corruption_error_count is compiled in
+  and can be examined to see if errors have occurred. This option
+  generates slower code than the default abort policy.
+
+DEBUG                    default: NOT defined
+  The DEBUG setting is mainly intended for people trying to modify
+  this code or diagnose problems when porting to new platforms.
+  However, it may also be able to better isolate user errors than just
+  using runtime checks.  The assertions in the check routines spell
+  out in more detail the assumptions and invariants underlying the
+  algorithms.  The checking is fairly extensive, and will slow down
+  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+  set will attempt to check every non-mmapped allocated and free chunk
+  in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
+  Debugging assertion failures can be nearly impossible if your
+  version of the assert macro causes malloc to be called, which will
+  lead to a cascade of further failures, blowing the runtime stack.
+  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+  which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
+  The action to take before "return 0" when malloc fails to be able to
+  return memory because there is none available.
+
+HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
+  True if this system supports sbrk or an emulation of it.
+
+MORECORE                  default: sbrk
+  The name of the sbrk-style system routine to call to obtain more
+  memory.  See below for guidance on writing custom MORECORE
+  functions. The type of the argument to sbrk/MORECORE varies across
+  systems.  It cannot be size_t, because it supports negative
+  arguments, so it is normally the signed type of the same width as
+  size_t (sometimes declared as "intptr_t").  It doesn't much matter
+  though. Internally, we only call it with arguments less than half
+  the max value of a size_t, which should work across all reasonable
+  possibilities, although sometimes generating compiler warnings.  See
+  near the end of this file for guidelines for creating a custom
+  version of MORECORE.
+
+MORECORE_CONTIGUOUS       default: 1 (true)
+  If true, take advantage of fact that consecutive calls to MORECORE
+  with positive arguments always return contiguous increasing
+  addresses.  This is true of unix sbrk. It does not hurt too much to
+  set it true anyway, since malloc copes with non-contiguities.
+  Setting it false when definitely non-contiguous saves time
+  and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM      default: NOT defined
+  True if MORECORE cannot release space back to the system when given
+  negative arguments. This is generally necessary only if you are
+  using a hand-crafted MORECORE function that cannot handle negative
+  arguments.
+
+HAVE_MMAP                 default: 1 (true)
+  True if this system supports mmap or an emulation of it.  If so, and
+  HAVE_MORECORE is not true, MMAP is used for all system
+  allocation. If set and HAVE_MORECORE is true as well, MMAP is
+  primarily used to directly allocate very large blocks. It is also
+  used as a backup strategy in cases where MORECORE fails to provide
+  space from system. Note: A single call to MUNMAP is assumed to be
+  able to unmap memory that may have be allocated using multiple calls
+  to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP               default: 1 on linux, else 0
+  If true realloc() uses mremap() to re-allocate large blocks and
+  extend or shrink allocation spaces.
+
+MMAP_CLEARS               default: 1 on unix
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero.
+
+USE_BUILTIN_FFS            default: 0 (i.e., not used)
+  Causes malloc to use the builtin ffs() function to compute indices.
+  Some compilers may recognize and intrinsify ffs to be faster than the
+  supplied C version. Also, the case of x86 using gcc is special-cased
+  to an asm instruction, so is already as fast as it can be, and so
+  this setting has no effect. (On most x86s, the asm version is only
+  slightly faster than the C version.)
+
+malloc_getpagesize         default: derive from system includes, or 4096.
+  The system page size. To the extent possible, this malloc manages
+  memory from the system in page-size units.  This may be (and
+  usually is) a function rather than a constant. This is ignored
+  if WIN32, where page size is determined using getSystemInfo during
+  initialization.
+
+USE_DEV_RANDOM             default: 0 (i.e., not used)
+  Causes malloc to use /dev/random to initialize secure magic seed for
+  stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO                default: 0
+  If defined, don't compile "mallinfo". This can be a simple way
+  of dealing with mismatches between system declarations and
+  those in this file.
+
+MALLINFO_FIELD_TYPE        default: size_t
+  The type of the fields in the mallinfo struct. This was originally
+  defined as "int" in SVID etc, but is more usefully defined as
+  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
+
+REALLOC_ZERO_BYTES_FREES    default: not defined
+  This should be set if a call to realloc with zero bytes should 
+  be the same as a call to free. Some people think it should. Otherwise, 
+  since this malloc returns a unique pointer for malloc(0), so does 
+  realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
+LACKS_STDLIB_H                default: NOT defined unless on WIN32
+  Define these if your system does not have these header files.
+  You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
+                                system_info.dwAllocationGranularity in WIN32,
+                                otherwise 64K.
+      Also settable using mallopt(M_GRANULARITY, x)
+  The unit for allocating and deallocating memory from the system.  On
+  most systems with contiguous MORECORE, there is no reason to
+  make this more than a page. However, systems with MMAP tend to
+  either require or encourage larger granularities.  You can increase
+  this value to prevent system allocation functions to be called so
+  often, especially if they are slow.  The value must be at least one
+  page and must be a power of two.  Setting to 0 causes initialization
+  to either page size or win32 region size.  (Note: In previous
+  versions of malloc, the equivalent of this option was called
+  "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD    default: 2MB
+      Also settable using mallopt(M_TRIM_THRESHOLD, x)
+  The maximum amount of unused top-most memory to keep before
+  releasing via malloc_trim in free().  Automatic trimming is mainly
+  useful in long-lived programs using contiguous MORECORE.  Because
+  trimming via sbrk can be slow on some systems, and can sometimes be
+  wasteful (in cases where programs immediately afterward allocate
+  more large chunks) the value should be high enough so that your
+  overall system performance would improve by releasing this much
+  memory.  As a rough guide, you might set to a value close to the
+  average size of a process (program) running on your system.
+  Releasing this much memory would allow such a process to run in
+  memory.  Generally, it is worth tuning trim thresholds when a
+  program undergoes phases where several large chunks are allocated
+  and released in ways that can reuse each other's storage, perhaps
+  mixed with phases where there are no such chunks at all. The trim
+  value must be greater than page size to have any useful effect.  To
+  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+  some people use of mallocing a huge space and then freeing it at
+  program startup, in an attempt to reserve system memory, doesn't
+  have the intended effect under automatic trimming, since that memory
+  will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD       default: 256K
+      Also settable using mallopt(M_MMAP_THRESHOLD, x)
+  The request size threshold for using MMAP to directly service a
+  request. Requests of at least this size that cannot be allocated
+  using already-existing space will be serviced via mmap.  (If enough
+  normal freed space already exists it is used instead.)  Using mmap
+  segregates relatively large chunks of memory so that they can be
+  individually obtained and released from the host system. A request
+  serviced through mmap is never reused by any other request (at least
+  not directly; the system may just so happen to remap successive
+  requests to the same locations).  Segregating space in this way has
+  the benefits that: Mmapped space can always be individually released
+  back to the system, which helps keep the system level memory demands
+  of a long-lived program low.  Also, mapped memory doesn't become
+  `locked' between other chunks, as can happen with normally allocated
+  chunks, which means that even trimming via malloc_trim would not
+  release them.  However, it has the disadvantage that the space
+  cannot be reclaimed, consolidated, and then used to service later
+  requests, as happens with normal chunks.  The advantages of mmap
+  nearly always outweigh disadvantages for "large" chunks, but the
+  value of "large" may vary across systems.  The default is an
+  empirically derived value that works well in most systems. You can
+  disable mmap by setting to MAX_SIZE_T.

+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and "chunks"
+  is null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use regular calloc and assign pointers into this
+  space to represent elements.  (In this case though, you cannot
+  independently free elements.)
+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:
+
+  struct Node { int item; struct Node* next; };
+
+  struct Node* build_list() {
+    struct Node** pool;
+    int n = read_number_of_nodes_needed();
+    if (n <= 0) return 0;
+    pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0);
+    if (pool == 0) die();
+    // organize into a linked list...
+    struct Node* first = pool[0];
+    for (i = 0; i < n-1; ++i)
+      pool[i]->next = pool[i+1];
+    free(pool);     // Can now free the array (or not, if it is needed later)
+    return first;
+  }

+  independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use a single regular malloc, and assign pointers at
+  particular offsets in the aggregate space. (In this case though, you
+  cannot independently free elements.)
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+
+  void send_message(char* msg) {
+    int msglen = strlen(msg);
+    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
+    void* chunks[3];
+    if (independent_comalloc(3, sizes, chunks) == 0)
+      die();
+    struct Head* head = (struct Head*)(chunks[0]);
+    char*        body = (char*)(chunks[1]);
+    struct Foot* foot = (struct Foot*)(chunks[2]);
+    // ...
+  }
+
+  In general though, independent_comalloc is worth using only for
+  larger values of n_elements. For small values, you probably won't
+  detect enough difference from series of malloc calls to bother.
+
+  Overuse of independent_comalloc can increase overall memory usage,
+  since it cannot reuse existing noncontiguous small chunks that
+  might be available for some of the elements.

+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+           | Size of previous chunk (if P = 1)                             |

+         +-                                                             -+

+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse. This redundancy enables usage checks within free and realloc,
+  and reduces indirection when freeing and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+        the one bordering the end of available memory). It is treated
+        specially.  Top is never included in any bin, is used only if
+        no other chunk is available, and is released back to the
+        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+        the top chunk is treated as larger (and thus less well
+        fitting) than any other available chunk.  The top chunk
+        doesn't update its trailing size field since there is no next
+        contiguous chunk that would have to index off it. However,
+        space is still allocated for it (TOP_FOOT_SIZE) to enable
+        separation or merging when space is extended.
+
+     3. Chunks allocated via mmap, which have the lowest-order bit
+        (IS_MMAPPED_BIT) set in their prev_foot fields, and do not set
+        PINUSE_BIT in their head fields.  Because they are allocated
+        one-by-one, each must carry its own prev_foot field, which is
+        also used to hold the offset this chunk has within its mmapped
+        region, which is needed to preserve alignment. Each mmapped
+        chunk is trailed by the first two fields of a fake next-chunk
+        for sake of usage checks.

+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size an an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child
+  pointers until we reach a null, here we follow the right child
+  pointer any time the left one is null, until we reach a leaf with
+  both child pointers null. The smallest chunk in the tree will be
+  somewhere along that path.
+
+  The worst case number of steps to add, find, or remove a node is
+  bounded by the number of bits differentiating chunks within
+  bins. Under current bin calculations, this ranges from 6 up to 21
+  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+  is of course much better.

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If IS_MMAPPED_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.

+/* ---------------------------- malloc_state ----------------------------- */
+
+/*
+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+    fenceposts and segment records if necessary when getting more
+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.

+  believe all pointers, sizes, maps etc held in malloc_state, but
+  check all of those linked or offsetted from other embedded data
+  structures.  These checks are interspersed with main code in a way
+  that tends to minimize their run-time cost.
+
+  When FOOTERS is defined, in addition to range checking, we also
+  verify footer fields of inuse chunks, which can be used guarantee
+  that the mstate controlling malloc/free is intact.  This is a
+  streamlined version of the approach described by William Robertson
+  et al in "Run-time Detection of Heap-based Overflows" LISA'03
+  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+  of an inuse chunk holds the xor of its mstate and a random seed,
+  that is checked upon calls to free() and realloc().  This is
+  (probablistically) unguessable from outside the program, but can be
+  computed by any code successfully malloc'ing any chunk, so does not
+  itself provide protection against code that has already broken
+  security through some other means.  Unlike Robertson et al, we
+  always dynamically check addresses of all offset chunks (previous,
+  next, etc). This turns out to be cheaper than relying on hashes.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+  Guidelines for creating a custom version of MORECORE:
+
+  * For best performance, MORECORE should allocate in multiples of pagesize.
+  * MORECORE may allocate more memory than requested. (Or even less,
+      but this will usually result in a malloc failure.)
+  * MORECORE must not allocate memory when given argument zero, but
+      instead return one past the end address of memory from previous
+      nonzero call.
+  * For best performance, consecutive calls to MORECORE with positive
+      arguments should return increasing addresses, indicating that
+      space has been contiguously extended.
+  * Even though consecutive calls to MORECORE need not return contiguous
+      addresses, it must be OK for malloc'ed chunks to span multiple
+      regions in those cases where they do happen to be contiguous.
+  * MORECORE need not handle negative arguments -- it may instead
+      just return MFAIL when given negative arguments.
+      Negative arguments are always multiples of pagesize. MORECORE
+      must not misinterpret negative args as large positive unsigned
+      args. You can suppress all such calls from even occurring by defining
+      MORECORE_CANNOT_TRIM,
+
+  As an example alternative MORECORE, here is a custom allocator
+  kindly contributed for pre-OSX macOS.  It uses virtually but not
+  necessarily physically contiguous non-paged memory (locked in,
+  present and won't get swapped out).  You can use it by uncommenting
+  this section, adding some #includes, and setting up the appropriate
+  defines above:
+
+      #define MORECORE osMoreCore
+
+  There is also a shutdown routine that should somehow be called for
+  cleanup upon program exit.
+
+  #define MAX_POOL_ENTRIES 100
+  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
+  static int next_os_pool;
+  void *our_os_pools[MAX_POOL_ENTRIES];

+  void *osMoreCore(int size)

+    void *ptr = 0;
+    static void *sbrk_top = 0;
+
+    if (size > 0)
+    {
+      if (size < MINIMUM_MORECORE_SIZE)
+         size = MINIMUM_MORECORE_SIZE;
+      if (CurrentExecutionLevel() == kTaskLevel)
+         ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);

+      * Optional footer checks. Thanks to William Robertson for the idea.
+      * Internal code refactoring
+      * Incorporate suggestions and platform-specific changes.
+        Thanks to Dennis Flanagan, Colin Plumb, Niall Douglas,
+        Aaron Bachmann,  Emery Berger, and others.
+      * Speed up non-fastbin processing enough to remove fastbins.
+      * Remove useless cfree() to avoid conflicts with other apps.
+      * Remove internal memcpy, memset. Compilers handle builtins better.
+      * Remove some options that no one ever used and rename others.
+
+    V2.7.2 Sat Aug 17 09:07:30 2002  Doug Lea  (dl at gee)
+      * Fix malloc_state bitmap array misdeclaration
+
+    V2.7.1 Thu Jul 25 10:58:03 2002  Doug Lea  (dl at gee)
+      * Allow tuning of FIRST_SORTED_BIN_SIZE
+      * Use PTR_UINT as type for all ptr->int casts. Thanks to John Belmonte.
+      * Better detection and support for non-contiguousness of MORECORE.
+        Thanks to Andreas Mueller, Conal Walsh, and Wolfram Gloger
+      * Bypass most of malloc if no frees. Thanks To Emery Berger.
+      * Fix freeing of old top non-contiguous chunk im sysmalloc.
+      * Raised default trim and map thresholds to 256K.
+      * Fix mmap-related #defines. Thanks to Lubos Lunak.
+      * Fix copy macros; added LACKS_FCNTL_H. Thanks to Neal Walfield.
+      * Branch-free bin calculation
+      * Default trim and mmap thresholds now 256K.
+
+    V2.7.0 Sun Mar 11 14:14:06 2001  Doug Lea  (dl at gee)

+      * Make optional .h file available
+      * Allow > 2GB requests on 32bit systems.
+      * new WIN32 sbrk, mmap, munmap, lock code from <Walter@GeNeSys-e.de>.
+        Thanks also to Andreas Mueller <a.mueller at paradatec.de>,
+        and Anonymous.
+      * Allow override of MALLOC_ALIGNMENT (Thanks to Ruud Waij for
+        helping test this.)
+      * memalign: check alignment arg
+      * realloc: don't try to shift chunks backwards, since this
+        leads to  more fragmentation in some programs and doesn't
+        seem to help in any others.
+      * Collect all cases in malloc requiring system memory into sysmalloc
+      * Use mmap as backup to sbrk
+      * Place all internal state in malloc_state

+        Thanks to Tony E. Bennett <tbennett@nvidia.com> and others.
+      * Include errno.h to support default failure action.
+
+    V2.6.6 Sun Dec  5 07:42:19 1999  Doug Lea  (dl at gee)
+      * return null for negative arguments
+      * Added Several WIN32 cleanups from Martin C. Fong <mcfong at yahoo.com>
+         * Add 'LACKS_SYS_PARAM_H' for those systems without 'sys/param.h'
+          (e.g. WIN32 platforms)
+         * Cleanup header file inclusion for WIN32 platforms
+         * Cleanup code to avoid Microsoft Visual C++ compiler complaints
+         * Add 'USE_DL_PREFIX' to quickly allow co-existence with existing
+           memory allocation routines
+         * Set 'malloc_getpagesize' for WIN32 platforms (needs more work)
+         * Use 'assert' rather than 'ASSERT' in WIN32 code to conform to
+           usage of 'assert' in non-WIN32 code
+         * Improve WIN32 'sbrk()' emulation's 'findRegion()' routine to
+           avoid infinite loop
+      * Always call 'fREe()' rather than 'free()'
+
+    V2.6.5 Wed Jun 17 15:57:31 1998  Doug Lea  (dl at gee)
+      * Fixed ordering problem with boundary-stamping
+
+    V2.6.3 Sun May 19 08:17:58 1996  Doug Lea  (dl at gee)
+      * Added pvalloc, as recommended by H.J. Liu
+      * Added 64bit pointer support mainly from Wolfram Gloger
+      * Added anonymously donated WIN32 sbrk emulation
+      * Malloc, calloc, getpagesize: add optimizations from Raymond Nijssen
+      * malloc_extend_top: fix mask error that caused wastage after
+        foreign sbrks
+      * Add linux mremap support code from HJ Liu
+
+    V2.6.2 Tue Dec  5 06:52:55 1995  Doug Lea  (dl at gee)
+      * Integrated most documentation with the code.
+      * Add support for mmap, with help from
+        Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Use last_remainder in more cases.
+      * Pack bins using idea from  colin@nyx10.cs.du.edu
+      * Use ordered bins instead of best-fit threshhold
+      * Eliminate block-local decls to simplify tracing and debugging.
+      * Support another case of realloc via move into top
+      * Fix error occuring when initial sbrk_base not word-aligned.
+      * Rely on page size for units instead of SBRK_UNIT to
+        avoid surprises about sbrk alignment conventions.
+      * Add mallinfo, mallopt. Thanks to Raymond Nijssen
+        (raymond@es.ele.tue.nl) for the suggestion.
+      * Add `pad' argument to malloc_trim and top_pad mallopt parameter.
+      * More precautions for cases where other routines call sbrk,
+        courtesy of Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Added macros etc., allowing use in linux libc from
+        H.J. Lu (hjl@gnu.ai.mit.edu)
+      * Inverted this history list
+
+    V2.6.1 Sat Dec  2 14:10:57 1995  Doug Lea  (dl at gee)
+      * Re-tuned and fixed to behave more nicely with V2.6.0 changes.
+      * Removed all preallocation code since under current scheme
+        the work required to undo bad preallocations exceeds
+        the work saved in good cases for most test programs.
+      * No longer use return list or unconsolidated bins since
+        no scheme using them consistently outperforms those that don't
+        given above changes.
+      * Use best fit for very large chunks to prevent some worst-cases.
+      * Added some support for debugging
+
+    V2.6.0 Sat Nov  4 07:05:23 1995  Doug Lea  (dl at gee)
+      * Removed footers when chunks are in use. Thanks to
+        Paul Wilson (wilson@cs.texas.edu) for the suggestion.
+
+    V2.5.4 Wed Nov  1 07:54:51 1995  Doug Lea  (dl at gee)
+      * Added malloc_trim, with help from Wolfram Gloger
+        (wmglo@Dent.MED.Uni-Muenchen.DE).
+
+    V2.5.3 Tue Apr 26 10:16:01 1994  Doug Lea  (dl at g)
+
+    V2.5.2 Tue Apr  5 16:20:40 1994  Doug Lea  (dl at g)
+      * realloc: try to expand in both directions
+      * malloc: swap order of clean-bin strategy;
+      * realloc: only conditionally expand backwards
+      * Try not to scavenge used bins
+      * Use bin counts as a guide to preallocation
+      * Occasionally bin return list chunks in first scan
+      * Add a few optimizations from colin@nyx10.cs.du.edu
+
+    V2.5.1 Sat Aug 14 15:40:43 1993  Doug Lea  (dl at g)
+      * faster bin computation & slightly different binning
+      * merged all consolidations to one part of malloc proper
+         (eliminating old malloc_find_space & malloc_clean_bin)
+      * Scan 2 returns chunks (not just 1)
+      * Propagate failure in realloc if malloc returns 0
+      * Add stuff to allow compilation on non-ANSI compilers
+          from kpv@research.att.com
+
+    V2.5 Sat Aug  7 07:41:59 1993  Doug Lea  (dl at g.oswego.edu)
+      * removed potential for odd address access in prev_chunk
+      * removed dependency on getpagesize.h
+      * misc cosmetics and a bit more internal documentation
+      * anticosmetics: mangled names in macros to evade debugger strangeness
+      * tested on sparc, hp-700, dec-mips, rs6000
+          with gcc & native cc (hp, dec only) allowing
+          Detlefs & Zorn comparison study (in SIGPLAN Notices.)
+
+    Trial version Fri Aug 28 13:14:29 1992  Doug Lea  (dl at g.oswego.edu)
+      * Based loosely on libg++-1.2X malloc. (It retains some of the overall
+         structure of old version,  but most details differ.)

+% As a special exception, when this file is read by TeX when processing
+% a Texinfo source document, you may use the result without
+% restriction.  (This has been our intent since Texinfo was invented.)
+%
+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+%   http://www.gnu.org/software/texinfo/ (the Texinfo home page), or
+%   ftp://tug.org/tex/texinfo.tex
+%     (and all CTAN mirrors, see http://www.ctan.org).
+% The texinfo.tex in any given distribution could well be out
+% of date, so if that's what you're using, please check.
+%
+% Send bug reports to bug-texinfo@gnu.org.  Please include including a
+% complete document in each bug report with which we can reproduce the
+% problem.  Patches are, of course, greatly appreciated.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+       y-1-x will not be exactly representable any more and the result can be

+   entire float domain.  Note that accuracy may depend on the quality of the
+   system math functions, the pow function in particular.  Special cases
+   follow C99 annex F.  The parameters and method are tailored to platforms
+   whose double format is the IEEE 754 binary64 format.
+
+   Method: for x > 0.0 we use the Lanczos approximation with parameters N=13
+   and g=6.024680040776729583740234375; these parameters are amongst those
+   used by the Boost library.  Following Boost (again), we re-express the
+   Lanczos sum as a rational function, and compute it that way.  The
+   coefficients below were computed independently using MPFR, and have been
+   double-checked against the coefficients in the Boost source code.
+
+   For x < 0.0 we use the reflection formula.
+
+   There's one minor tweak that deserves explanation: Lanczos' formula for
+   Gamma(x) involves computing pow(x+g-0.5, x-0.5) / exp(x+g-0.5).  For many x
+   values, x+g-0.5 can be represented exactly.  However, in cases where it
+   can't be represented exactly the small error in x+g-0.5 can be magnified
+   significantly by the pow and exp calls, especially for large x.  A cheap
+   correction is to multiply by (1 + e*g/(x+g-0.5)), where e is the error
+   involved in the computation of x+g-0.5 (that is, e = computed value of
+   x+g-0.5 - exact value of x+g-0.5).  Here's the proof:
+
+   Correction factor
+   -----------------
+   Write x+g-0.5 = y-e, where y is exactly representable as an IEEE 754
+   double, and e is tiny.  Then:
+
+     pow(x+g-0.5,x-0.5)/exp(x+g-0.5) = pow(y-e, x-0.5)/exp(y-e)
+     = pow(y, x-0.5)/exp(y) * C,
+
+   where the correction_factor C is given by
+
+     C = pow(1-e/y, x-0.5) * exp(e)
+
+   Since e is tiny, pow(1-e/y, x-0.5) ~ 1-(x-0.5)*e/y, and exp(x) ~ 1+e, so:
+
+     C ~ (1-(x-0.5)*e/y) * (1+e) ~ 1 + e*(y-(x-0.5))/y
+
+   But y-(x-0.5) = g+e, and g+e ~ g.  So we get C ~ 1 + e*g/y, and
+
+     pow(x+g-0.5,x-0.5)/exp(x+g-0.5) ~ pow(y, x-0.5)/exp(y) * (1 + e*g/y),
+
+   Note that for accuracy, when computing r*C it's better to do
+
+     r + e*g/y*r;
+
+   than
+
+     r * (1 + e*g/y);
+
+   since the addition in the latter throws away most of the bits of
+   information in e*g/y.

+   Implementations of the error function erf(x) and the complementary error
+   function erfc(x).
+
+   Method: following 'Numerical Recipes' by Flannery, Press et. al. (2nd ed.,
+   Cambridge University Press), we use a series approximation for erf for
+   small x, and a continued fraction approximation for erfc(x) for larger x;
+   combined with the relations erf(-x) = -erf(x) and erfc(x) = 1.0 - erf(x),
+   this gives us erf(x) and erfc(x) for all x.
+
+   The series expansion used is:
+
+      erf(x) = x*exp(-x*x)/sqrt(pi) * [
+                     2/1 + 4/3 x**2 + 8/15 x**4 + 16/105 x**6 + ...]
+
+   The coefficient of x**(2k-2) here is 4**k*factorial(k)/factorial(2*k).
+   This series converges well for smallish x, but slowly for larger x.
+
+   The continued fraction expansion used is:
+
+      erfc(x) = x*exp(-x*x)/sqrt(pi) * [1/(0.5 + x**2 -) 0.5/(2.5 + x**2 - )
+                              3.0/(4.5 + x**2 - ) 7.5/(6.5 + x**2 - ) ...]
+
+   after the first term, the general term has the form:
+
+      k*(k-0.5)/(2*k+0.5 + x**2 - ...).
+
+   This expansion converges fast for larger x, but convergence becomes
+   infinitely slow as x approaches 0.0.  The (somewhat naive) continued
+   fraction evaluation algorithm used below also risks overflow for large x;
+   but for large x, erfc(x) == 0.0 to within machine precision.  (For
+   example, erfc(30.0) is approximately 2.56e-393).
+
+   Parameters: use series expansion for abs(x) < ERF_SERIES_CUTOFF and
+   continued fraction expansion for ERF_SERIES_CUTOFF <= abs(x) <
+   ERFC_CONTFRAC_CUTOFF.  ERFC_SERIES_TERMS and ERFC_CONTFRAC_TERMS are the
+   numbers of terms to use for the relevant expansions.  */

+ *
+ * Notes on the algorithm
+ * ----------------------
+ *
+ * factorial(n) is written in the form 2**k * m, with m odd.  k and m are
+ * computed separately, and then combined using a left shift.
+ *
+ * The function factorial_odd_part computes the odd part m (i.e., the greatest
+ * odd divisor) of factorial(n), using the formula:
+ *
+ *   factorial_odd_part(n) =
+ *
+ *        product_{i >= 0} product_{0 < j <= n / 2**i, j odd} j
+ *
+ * Example: factorial_odd_part(20) =
+ *
+ *        (1) *
+ *        (1) *
+ *        (1 * 3 * 5) *
+ *        (1 * 3 * 5 * 7 * 9)
+ *        (1 * 3 * 5 * 7 * 9 * 11 * 13 * 15 * 17 * 19)
+ *
+ * Here i goes from large to small: the first term corresponds to i=4 (any
+ * larger i gives an empty product), and the last term corresponds to i=0.
+ * Each term can be computed from the last by multiplying by the extra odd
+ * numbers required: e.g., to get from the penultimate term to the last one,
+ * we multiply by (11 * 13 * 15 * 17 * 19).
+ *
+ * To see a hint of why this formula works, here are the same numbers as above
+ * but with the even parts (i.e., the appropriate powers of 2) included.  For
+ * each subterm in the product for i, we multiply that subterm by 2**i:
+ *
+ *   factorial(20) =
+ *
+ *        (16) *
+ *        (8) *
+ *        (4 * 12 * 20) *
+ *        (2 * 6 * 10 * 14 * 18) *
+ *        (1 * 3 * 5 * 7 * 9 * 11 * 13 * 15 * 17 * 19)
+ *

 33. Does zlib have any security vulnerabilities?
 
-    The only one that we are aware of is potentially in gzprintf(). If zlib

 34. Is there a Java version of zlib?
 
     Probably what you want is to use zlib in Java. zlib is already included

     Isn't that a bug?
 
-    No.  That is intentional for performance reasons, and the output of

-# library is created. If the primitive shared library support provided here
-# does not work, use ftp://prep.ai.mit.edu/pub/gnu/libtool-*.tar.gz
+# Normally configure builds both a static and a shared library.
+# If you want to build just a static library, use: ./configure --static
 #
 # To impose specific compiler or flags or install directory, use for example:
 #    prefix=$HOME CC=cc CFLAGS="-O4" ./configure
 # or for csh/tcsh users:
 #    (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
-# LDSHARED is the command to be used to create a shared library
 
 # Incorrect settings of CC or CFLAGS may prevent creating a shared library.
 # If you have problems, try without defining CC and CFLAGS before reporting
 # an error.

-/* All about c_lnotab.
-
-c_lnotab is an array of unsigned bytes disguised as a Python string.  In -O
-mode, SET_LINENO opcodes aren't generated, and bytecode offsets are mapped
-to source code line #s (when needed for tracebacks) via c_lnotab instead.
-The array is conceptually a list of
-    (bytecode offset increment, line number increment)
-pairs.  The details are important and delicate, best illustrated by example:
-
-    byte code offset    source code line number
-    0                       1
-    6                       2
-       50                   7
-      350                 307
-      361                 308
-
-The first trick is that these numbers aren't stored, only the increments
-from one row to the next (this doesn't really work, but it's a start):
-
-    0, 1,  6, 1,  44, 5,  300, 300,  11, 1
-
-The second trick is that an unsigned byte can't hold negative values, or
-values larger than 255, so (a) there's a deep assumption that byte code
-offsets and their corresponding line #s both increase monotonically, and (b)
-if at least one column jumps by more than 255 from one row to the next, more
-than one pair is written to the table. In case #b, there's no way to know
-from looking at the table later how many were written.  That's the delicate
-part.  A user of c_lnotab desiring to find the source line number
-corresponding to a bytecode address A should do something like this
-
-    lineno = addr = 0
-    for addr_incr, line_incr in c_lnotab:
-    addr += addr_incr
-    if addr > A:
-        return lineno
-    lineno += line_incr
-
-In order for this to work, when the addr field increments by more than 255,
-the line # increment in each pair generated must be 0 until the remaining addr
-increment is < 256.  So, in the example above, com_set_lineno should not (as
-was actually done until 2.2) expand 300, 300 to 255, 255,  45, 45, but to
-255, 0,  45, 255,  0, 45.

-/*
-   Check whether the current instruction is at the start of a line.

-
-    /* The theory of SET_LINENO-less tracing.
-
-       In a nutshell, we use the co_lnotab field of the code object
-       to tell when execution has moved onto a different line.
-
-       As mentioned above, the basic idea is so set things up so
-       that
-
-         *instr_lb <= frame->f_lasti < *instr_ub
-
-       is true so long as execution does not change lines.
-
-       This is all fairly simple.  Digging the information out of
-       co_lnotab takes some work, but is conceptually clear.
-
-       Somewhat harder to explain is why we don't *always* call the
-       line trace function when the above test fails.
-
-       Consider this code:
-
-       1: def f(a):
-       2:     if a:
-       3:        print 1
-       4:     else:
-       5:        print 2
-
-       which compiles to this:
-
-       2           0 LOAD_FAST                0 (a)
-                   3 JUMP_IF_FALSE            9 (to 15)
-                   6 POP_TOP
-
-       3           7 LOAD_CONST               1 (1)
-                  10 PRINT_ITEM
-                  11 PRINT_NEWLINE
-                  12 JUMP_FORWARD             6 (to 21)
-         >>   15 POP_TOP
-
-       5          16 LOAD_CONST               2 (2)
-                  19 PRINT_ITEM
-                  20 PRINT_NEWLINE
-         >>   21 LOAD_CONST               0 (None)
-              24 RETURN_VALUE
-
-       If 'a' is false, execution will jump to instruction at offset
-       15 and the co_lnotab will claim that execution has moved to
-       line 3.  This is at best misleading.  In this case we could
-       associate the POP_TOP with line 4, but that doesn't make
-       sense in all cases (I think).
-
-       What we do is only call the line trace function if the co_lnotab
-       indicates we have jumped to the *start* of a line, i.e. if the
-       current instruction offset matches the offset given for the
-       start of a line by the co_lnotab.
-
-       This also takes care of the situation where 'a' is true.
-       Execution will jump from instruction offset 12 to offset 21.
-       Then the co_lnotab would imply that execution has moved to line
-       5, which is again misleading.
-
-       Why do we set f_lineno when tracing?  Well, consider the code
-       above when 'a' is true.  If stepping through this with 'n' in
-       pdb, you would stop at line 1 with a "call" type event, then
-       line events on lines 2 and 3, then a "return" type event -- but
-       you would be shown line 5 during this event.  This is a change
-       from the behaviour in 2.2 and before, and I've found it
-       confusing in practice.  By setting and using f_lineno when
-       tracing, one can report a line number different from that
-       suggested by f_lasti on this one occasion where it's desirable.

+All about co_lnotab, the line number table.
+
+Code objects store a field named co_lnotab.  This is an array of unsigned bytes
+disguised as a Python string.  It is used to map bytecode offsets to source code
+line #s for tracebacks and to identify line number boundaries for line tracing.
+
+The array is conceptually a compressed list of
+    (bytecode offset increment, line number increment)
+pairs.  The details are important and delicate, best illustrated by example:
+
+    byte code offset    source code line number
+        0		    1
+        6		    2
+       50		    7
+      350                 307
+      361                 308
+
+Instead of storing these numbers literally, we compress the list by storing only
+the increments from one row to the next.  Conceptually, the stored list might
+look like:
+
+    0, 1,  6, 1,  44, 5,  300, 300,  11, 1
+
+The above doesn't really work, but it's a start. Note that an unsigned byte
+can't hold negative values, or values larger than 255, and the above example
+contains two such values. So we make two tweaks:
+
+ (a) there's a deep assumption that byte code offsets and their corresponding
+ line #s both increase monotonically, and
+ (b) if at least one column jumps by more than 255 from one row to the next,
+ more than one pair is written to the table. In case #b, there's no way to know
+ from looking at the table later how many were written.  That's the delicate
+ part.  A user of co_lnotab desiring to find the source line number
+ corresponding to a bytecode address A should do something like this
+
+    lineno = addr = 0
+    for addr_incr, line_incr in co_lnotab:
+        addr += addr_incr
+        if addr > A:
+            return lineno
+        lineno += line_incr
+
+(In C, this is implemented by PyCode_Addr2Line().)  In order for this to work,
+when the addr field increments by more than 255, the line # increment in each
+pair generated must be 0 until the remaining addr increment is < 256.  So, in
+the example above, assemble_lnotab in compile.c should not (as was actually done
+until 2.2) expand 300, 300 to
+    255, 255, 45, 45,
+but to
+    255, 0, 45, 255, 0, 45.
+
+The above is sufficient to reconstruct line numbers for tracebacks, but not for
+line tracing.  Tracing is handled by PyCode_CheckLineNumber() in codeobject.c
+and maybe_call_line_trace() in ceval.c.
+
+*** Tracing ***
+
+To a first approximation, we want to call the tracing function when the line
+number of the current instruction changes.  Re-computing the current line for
+every instruction is a little slow, though, so each time we compute the line
+number we save the bytecode indices where it's valid:
+
+     *instr_lb <= frame->f_lasti < *instr_ub
+
+is true so long as execution does not change lines.  That is, *instr_lb holds
+the first bytecode index of the current line, and *instr_ub holds the first
+bytecode index of the next line.  As long as the above expression is true,
+maybe_call_line_trace() does not need to call PyCode_CheckLineNumber().  Note
+that the same line may appear multiple times in the lnotab, either because the
+bytecode jumped more than 255 indices between line number changes or because
+the compiler inserted the same line twice.  Even in that case, *instr_ub holds
+the first index of the next line.
+
+However, we don't *always* want to call the line trace function when the above
+test fails.
+
+Consider this code:
+
+1: def f(a):
+2:    while a:
+3:       print 1,
+4:       break
+5:    else:
+6:       print 2,
+
+which compiles to this:
+
+  2           0 SETUP_LOOP              19 (to 22)
+        >>    3 LOAD_FAST                0 (a)
+              6 POP_JUMP_IF_FALSE       17
+
+  3           9 LOAD_CONST               1 (1)
+             12 PRINT_ITEM          
+
+  4          13 BREAK_LOOP          
+             14 JUMP_ABSOLUTE            3
+        >>   17 POP_BLOCK           
+
+  6          18 LOAD_CONST               2 (2)
+             21 PRINT_ITEM          
+        >>   22 LOAD_CONST               0 (None)
+             25 RETURN_VALUE        
+
+If 'a' is false, execution will jump to the POP_BLOCK instruction at offset 17
+and the co_lnotab will claim that execution has moved to line 4, which is wrong.
+In this case, we could instead associate the POP_BLOCK with line 5, but that
+would break jumps around loops without else clauses.
+
+We fix this by only calling the line trace function for a forward jump if the
+co_lnotab indicates we have jumped to the *start* of a line, i.e. if the current
+instruction offset matches the offset given for the start of a line by the
+co_lnotab.  For backward jumps, however, we always call the line trace function,
+which lets a debugger stop on every evaluation of a loop guard (which usually
+won't be the first opcode in a line).
+
+Why do we set f_lineno when tracing, and only just before calling the trace
+function?  Well, consider the code above when 'a' is true.  If stepping through
+this with 'n' in pdb, you would stop at line 1 with a "call" type event, then
+line events on lines 2, 3, and 4, then a "return" type event -- but because the
+code for the return actually falls in the range of the "line 6" opcodes, you
+would be shown line 6 during this event.  This is a change from the behaviour in
+2.2 and before, and I've found it confusing in practice.  By setting and using
+f_lineno when tracing, one can report a line number different from that
+suggested by f_lasti on this one occasion where it's desirable.

-       end; for small v no rounding is necessary.)  Write n for the number
-       of bits in v, so that 2**(n-1) <= v < 2**n, and n > DBL_MANT_DIG.
-
-       Some terminology: the *rounding bit* of v is the 1st bit of v that
-       will be rounded away (bit n - DBL_MANT_DIG - 1); the *parity bit*
-       is the bit immediately above.  The round-half-to-even rule says
-       that we round up if the rounding bit is set, unless v is exactly
-       halfway between two floats and the parity bit is zero.
-
-       Write d[0] ... d[m] for the digits of v, least to most significant.
-       Let rnd_bit be the index of the rounding bit, and rnd_digit the
-       index of the PyLong digit containing the rounding bit.  Then the
-       bits of the digit d[rnd_digit] look something like:
-
-              rounding bit
-              |
-              v
-          msb -> sssssrttttttttt <- lsb
-                     ^
-                     |
-              parity bit
-
-       where 's' represents a 'significant bit' that will be included in
-       the mantissa of the result, 'r' is the rounding bit, and 't'
-       represents a 'trailing bit' following the rounding bit.  Note that
-       if the rounding bit is at the top of d[rnd_digit] then the parity
-       bit will be the lsb of d[rnd_digit+1].  If we set
-
-          lsb = 1 << (rnd_bit % PyLong_SHIFT)
-
-       then d[rnd_digit] & (PyLong_BASE - 2*lsb) selects just the
-       significant bits of d[rnd_digit], d[rnd_digit] & (lsb-1) gets the
-       trailing bits, and d[rnd_digit] & lsb gives the rounding bit.
-
-       We initialize the double x to the integer given by digits
-       d[rnd_digit:m-1], but with the rounding bit and trailing bits of
-       d[rnd_digit] masked out.  So the value of x comes from the top
-       DBL_MANT_DIG bits of v, multiplied by 2*lsb.  Note that in the loop
-       that produces x, all floating-point operations are exact (assuming
-       that FLT_RADIX==2).  Now if we're rounding down, the value we want
-       to return is simply
-
-          x * 2**(PyLong_SHIFT * rnd_digit).
-
-       and if we're rounding up, it's
-
-          (x + 2*lsb) * 2**(PyLong_SHIFT * rnd_digit).
-
-       Under the round-half-to-even rule, we round up if, and only
-       if, the rounding bit is set *and* at least one of the
-       following three conditions is satisfied:
-
-          (1) the parity bit is set, or
-          (2) at least one of the trailing bits of d[rnd_digit] is set, or
-          (3) at least one of the digits d[i], 0 <= i < rnd_digit
-         is nonzero.
-
-       Finally, we have to worry about overflow.  If v >= 2**DBL_MAX_EXP,
-       or equivalently n > DBL_MAX_EXP, then overflow occurs.  If v <
-       2**DBL_MAX_EXP then we're usually safe, but there's a corner case
-       to consider: if v is very close to 2**DBL_MAX_EXP then it's
-       possible that v is rounded up to exactly 2**DBL_MAX_EXP, and then
-       again overflow occurs.

+

+
+             x * 2**PyLong_SHIFT = y + z (mod _PyHASH_MODULUS).
+
+           The right-hand side is just the result of rotating the

+         1. choose a suitable integer 'shift'
+         2. use integer arithmetic to compute x = floor(2**-shift*a/b)
+         3. adjust x for correct rounding
+         4. convert x to a double dx with the same value
+         5. return ldexp(dx, shift).
+
+       In more detail:
+
+       0. For any a, a/0 raises ZeroDivisionError; for nonzero b, 0/b
+       returns either 0.0 or -0.0, depending on the sign of b.  For a and
+       b both nonzero, ignore signs of a and b, and add the sign back in
+       at the end.  Now write a_bits and b_bits for the bit lengths of a
+       and b respectively (that is, a_bits = 1 + floor(log_2(a)); likewise
+       for b).  Then
+
+          2**(a_bits - b_bits - 1) < a/b < 2**(a_bits - b_bits + 1).
+
+       So if a_bits - b_bits > DBL_MAX_EXP then a/b > 2**DBL_MAX_EXP and
+       so overflows.  Similarly, if a_bits - b_bits < DBL_MIN_EXP -
+       DBL_MANT_DIG - 1 then a/b underflows to 0.  With these cases out of
+       the way, we can assume that
+
+          DBL_MIN_EXP - DBL_MANT_DIG - 1 <= a_bits - b_bits <= DBL_MAX_EXP.
+
+       1. The integer 'shift' is chosen so that x has the right number of
+       bits for a double, plus two or three extra bits that will be used
+       in the rounding decisions.  Writing a_bits and b_bits for the
+       number of significant bits in a and b respectively, a
+       straightforward formula for shift is:
+
+          shift = a_bits - b_bits - DBL_MANT_DIG - 2
+
+       This is fine in the usual case, but if a/b is smaller than the
+       smallest normal float then it can lead to double rounding on an
+       IEEE 754 platform, giving incorrectly rounded results.  So we
+       adjust the formula slightly.  The actual formula used is:
+
+           shift = MAX(a_bits - b_bits, DBL_MIN_EXP) - DBL_MANT_DIG - 2
+
+       2. The quantity x is computed by first shifting a (left -shift bits
+       if shift <= 0, right shift bits if shift > 0) and then dividing by
+       b.  For both the shift and the division, we keep track of whether
+       the result is inexact, in a flag 'inexact'; this information is
+       needed at the rounding stage.
+
+       With the choice of shift above, together with our assumption that
+       a_bits - b_bits >= DBL_MIN_EXP - DBL_MANT_DIG - 1, it follows
+       that x >= 1.
+
+       3. Now x * 2**shift <= a/b < (x+1) * 2**shift.  We want to replace
+       this with an exactly representable float of the form
+
+          round(x/2**extra_bits) * 2**(extra_bits+shift).
+
+       For float representability, we need x/2**extra_bits <
+       2**DBL_MANT_DIG and extra_bits + shift >= DBL_MIN_EXP -
+       DBL_MANT_DIG.  This translates to the condition:
+
+          extra_bits >= MAX(x_bits, DBL_MIN_EXP - shift) - DBL_MANT_DIG
+
+       To round, we just modify the bottom digit of x in-place; this can
+       end up giving a digit with value > PyLONG_MASK, but that's not a
+       problem since digits can hold values up to 2*PyLONG_MASK+1.
+
+       With the original choices for shift above, extra_bits will always
+       be 2 or 3.  Then rounding under the round-half-to-even rule, we
+       round up iff the most significant of the extra bits is 1, and
+       either: (a) the computation of x in step 2 had an inexact result,
+       or (b) at least one other of the extra bits is 1, or (c) the least
+       significant bit of x (above those to be rounded) is 1.
+
+       4. Conversion to a double is straightforward; all floating-point
+       operations involved in the conversion are exact, so there's no
+       danger of rounding errors.
+
+       5. Use ldexp(x, shift) to compute x*2**shift, the final result.
+       The result will always be exactly representable as a double, except
+       in the case that it overflows.  To avoid dependence on the exact
+       behaviour of ldexp on overflow, we check for overflow before
+       applying ldexp.  The result of ldexp is adjusted for sign before
+       returning.

-          (2) round to nearest integer (round to even in case of tie)
-          (3) multiply result by 10**n.
-
-       But the rounding step involves examining the fractional part of the
-       quotient to see whether it's greater than 0.5 or not.  Since we
-       want to do the whole calculation in integer arithmetic, it's
-       simpler to do:
-
-          (1) divide by (10**n)/2
-          (2) round to nearest multiple of 2 (multiple of 4 in case of tie)
-          (3) multiply result by (10**n)/2.
-
-       Then all we need to know about the fractional part of the quotient
-       arising in step (2) is whether it's zero or not.
-
-       Doing both a multiplication and division is wasteful, and is easily
-       avoided if we just figure out how much to adjust the original input
-       by to do the rounding.

+/* For numeric types, the hash of a number x is based on the reduction
+   of x modulo the prime P = 2**_PyHASH_BITS - 1.  It's designed so that
+   hash(x) == hash(y) whenever x and y are numerically equal, even if
+   x and y have different types.
+
+   A quick summary of the hashing strategy:
+
+   (1) First define the 'reduction of x modulo P' for any rational
+   number x; this is a standard extension of the usual notion of
+   reduction modulo P for integers.  If x == p/q (written in lowest
+   terms), the reduction is interpreted as the reduction of p times
+   the inverse of the reduction of q, all modulo P; if q is exactly
+   divisible by P then define the reduction to be infinity.  So we've
+   got a well-defined map
+
+      reduce : { rational numbers } -> { 0, 1, 2, ..., P-1, infinity }.
+
+   (2) Now for a rational number x, define hash(x) by:
+
+      reduce(x)   if x >= 0
+      -reduce(-x) if x < 0
+
+   If the result of the reduction is infinity (this is impossible for
+   integers, floats and Decimals) then use the predefined hash value
+   _PyHASH_INF for x >= 0, or -_PyHASH_INF for x < 0, instead.
+   _PyHASH_INF, -_PyHASH_INF and _PyHASH_NAN are also used for the
+   hashes of float and Decimal infinities and nans.
+
+   A selling point for the above strategy is that it makes it possible
+   to compute hashes of decimal and binary floating-point numbers
+   efficiently, even if the exponent of the binary or decimal number
+   is large.  The key point is that
+
+      reduce(x * y) == reduce(x) * reduce(y) (modulo _PyHASH_MODULUS)
+
+   provided that {reduce(x), reduce(y)} != {0, infinity}.  The reduction of a
+   binary or decimal float is never infinity, since the denominator is a power
+   of 2 (for binary) or a divisor of a power of 10 (for decimal).  So we have,
+   for nonnegative x,
+
+      reduce(x * 2**e) == reduce(x) * reduce(2**e) % _PyHASH_MODULUS
+
+      reduce(x * 10**e) == reduce(x) * reduce(10**e) % _PyHASH_MODULUS
+
+   and reduce(10**e) can be computed efficiently by the usual modular
+   exponentiation algorithm.  For reduce(2**e) it's even better: since
+   P is of the form 2**n-1, reduce(2**e) is 2**(e mod n), and multiplication
+   by 2**(e mod n) modulo 2**n-1 just amounts to a rotation of bits.

+   Notes about the implementation:
+
+   - The GIL is just a boolean variable (gil_locked) whose access is protected
+     by a mutex (gil_mutex), and whose changes are signalled by a condition
+     variable (gil_cond). gil_mutex is taken for short periods of time,
+     and therefore mostly uncontended.
+
+   - In the GIL-holding thread, the main loop (PyEval_EvalFrameEx) must be
+     able to release the GIL on demand by another thread. A volatile boolean
+     variable (gil_drop_request) is used for that purpose, which is checked
+     at every turn of the eval loop. That variable is set after a wait of
+     `interval` microseconds on `gil_cond` has timed out.
+      
+      [Actually, another volatile boolean variable (eval_breaker) is used
+       which ORs several conditions into one. Volatile booleans are
+       sufficient as inter-thread signalling means since Python is run
+       on cache-coherent architectures only.]
+
+   - A thread wanting to take the GIL will first let pass a given amount of
+     time (`interval` microseconds) before setting gil_drop_request. This
+     encourages a defined switching period, but doesn't enforce it since
+     opcodes can take an arbitrary time to execute.
+ 
+     The `interval` value is available for the user to read and modify
+     using the Python API `sys.{get,set}switchinterval()`.
+
+   - When a thread releases the GIL and gil_drop_request is set, that thread
+     ensures that another GIL-awaiting thread gets scheduled.
+     It does so by waiting on a condition variable (switch_cond) until
+     the value of gil_last_holder is changed to something else than its
+     own thread state pointer, indicating that another thread was able to
+     take the GIL.
+ 
+     This is meant to prohibit the latency-adverse behaviour on multi-core
+     machines where one thread would speculatively release the GIL, but still
+     run and end up being the first to re-acquire it, making the "timeslices"
+     much longer than expected.
+     (Note: this mechanism is enabled with FORCE_SWITCHING above)

-/* All about a_lnotab.
-
-c_lnotab is an array of unsigned bytes disguised as a Python string.
-It is used to map bytecode offsets to source code line #s (when needed
-for tracebacks).
-
-The array is conceptually a list of
-    (bytecode offset increment, line number increment)
-pairs.  The details are important and delicate, best illustrated by example:
-
-    byte code offset    source code line number
-    0                       1
-    6                       2
-       50                   7
-      350                 307
-      361                 308
-
-The first trick is that these numbers aren't stored, only the increments
-from one row to the next (this doesn't really work, but it's a start):
-
-    0, 1,  6, 1,  44, 5,  300, 300,  11, 1
-
-The second trick is that an unsigned byte can't hold negative values, or
-values larger than 255, so (a) there's a deep assumption that byte code
-offsets and their corresponding line #s both increase monotonically, and (b)
-if at least one column jumps by more than 255 from one row to the next, more
-than one pair is written to the table. In case #b, there's no way to know
-from looking at the table later how many were written.  That's the delicate
-part.  A user of c_lnotab desiring to find the source line number
-corresponding to a bytecode address A should do something like this
-
-    lineno = addr = 0
-    for addr_incr, line_incr in c_lnotab:
-    addr += addr_incr
-    if addr > A:
-        return lineno
-    lineno += line_incr
-
-In order for this to work, when the addr field increments by more than 255,
-the line # increment in each pair generated must be 0 until the remaining addr
-increment is < 256.  So, in the example above, assemble_lnotab (it used
-to be called com_set_lineno) should not (as was actually done until 2.2)
-expand 300, 300 to 255, 255, 45, 45,
-            but to 255,   0, 45, 255, 0, 45.

+       fills the buffer?  By appending 4 more characters onto the string
+       here, we could overrun the buffer.
+
+       As a simple example, let's say buflen=32 and the input string is
+       'xxx.py'.  strlen() would be 6 and the test above would yield:
+
+       (6 + 11 + 10 + 5 == 32) > 32
+
+       which is false and so the name mangling would continue.  This would
+       be fine because we'd end up with this string in buf:
+
+       __pycache__/xxx.cpython-32.pyc\0
+
+       strlen(of that) == 30 + the nul fits inside a 32 character buffer.
+       We can even handle an input string of say 'xxxxx' above because
+       that's (5 + 11 + 10 + 5 == 31) > 32 which is also false.  Name
+       mangling that yields:
+
+       __pycache__/xxxxxcpython-32.pyc\0
+
+       which is 32 characters including the nul, and thus fits in the
+       buffer. However, an input string of 'xxxxxx' would yield a result
+       string of:
+
+       __pycache__/xxxxxxcpython-32.pyc\0
+
+       which is 33 characters long (including the nul), thus overflowing
+       the buffer, even though the first test would fail, i.e.: the input
+       string is also 6 characters long, so 32 > 32 is false.
+
+       The reason the first test fails but we still overflow the buffer is
+       that the test above only expects to add one extra character to be
+       added to the extension, and here we're adding three (pyc).  We
+       don't add the first dot, so that reclaims one of expected
+       positions, leaving us overflowing by 1 byte (3 extra - 1 reclaimed
+       dot - 1 expected extra == 1 overflowed).
+
+       The best we can do is ensure that we still have enough room in the
+       target buffer before we write the extension.  Because it's always
+       only the extension that can cause the overflow, and never the other
+       path bytes we've written, it's sufficient to just do one more test
+       here.  Still, the assertion that follows can't hurt.

 A source-to-source translation tool, "2to3", can take care of the mundane task
 of converting large amounts of source code.  It is not a complete solution but
 is complemented by the deprecation warnings in 2.6.  See
-http://docs.python.org/py3k/library/2to3.html for more information.

 Testing
 -------
 
-To test the interpreter, type "make test" in the top-level directory.
-This runs the test set twice (once with no compiled files, once with
-the compiled files left by the previous test run).  The test set
-produces some output.  You can generally ignore the messages about
-skipped tests due to optional features which can't be imported.
-If a message is printed about a failed test or a traceback or core
-dump is produced, something is wrong.  On some Linux systems (those
-that are not yet using glibc 6), test_strftime fails due to a
-non-standard implementation of strftime() in the C library. Please
-ignore this, or upgrade to glibc version 6.

 Installing multiple versions
 ----------------------------
 
 On Unix and Mac systems if you intend to install multiple versions of Python
-using the same installation prefix (--prefix argument to the configure
-script) you must take care that your primary python executable is not
-overwritten by the installation of a different version.  All files and
-directories installed using "make altinstall" contain the major and minor
-version and can thus live side-by-side.  "make install" also creates
-${prefix}/bin/python3 which refers to ${prefix}/bin/pythonX.Y.  If you intend
-to install multiple versions using the same prefix you must decide which
-version (if any) is your "primary" version.  Install that version using
-"make install".  Install all other versions using "make altinstall".

-For example, if you want to install Python 2.5, 2.6 and 3.0 with 2.6 being
-the primary version, you would execute "make install" in your 2.6 build
-directory and "make altinstall" in the others.

-FAQ Wizard
-----------
-
-Author: Guido van Rossum <guido@python.org>
-Version: 1.0
-Date:  6 April 1998
-
-
-This is a CGI program that maintains a user-editable FAQ.  It uses RCS
-to keep track of changes to individual FAQ entries.  It is fully
-configurable; everything you might want to change when using this
-program to maintain some other FAQ than the Python FAQ is contained in
-the configuration module, faqconf.py.
-
-Note that the bulk of the code is not an executable script; it's an
-importable module.  The actual script in cgi-bin is minimal.
-
-Files:
-
-faqw.py		executable script to be edited and installed in cgi-bin
-faqwiz.py	main module, lives in same directory as FAQ entry files
-faqconf.py	main configuration module
-faqcust.py	additional local customization module (optional)
-move-faqwiz.sh  Script to move faqwiz entries.
-
-
-What's New?
------------
-
-Version 1.0 corrects some minor bugs and uses tab-agnostic
-indentation; it is otherwise unchanged from version 0.9.0.
-
-Version 0.9.0 uses the re module (Perl style regular expressions) for
-all its regular expression needs, instead of the regex and regsub
-modules (Emacs style).  This affects the syntax for regular
-expressions entered by the user as search strings (with "regular
-expression" checked), hence the version number jump.
-
-
-Setup Information
------------------
-
-This assumes you are familiar with Python, with your http server, and
-with running CGI scripts under your http server.  You need Python 1.5
-or better.
-
-Select a place where the Python modules that constitute the FAQ wizard
-will live (the directory where you unpacked it is an obvious choice).
-This will be called the SRCDIR.  This directory should not be writable
-by other users of your system (since they would be able to execute
-arbitrary code by invoking the FAQ wizard's CGI script).
-
-Create a dedicated working directory, preferably one that's not
-directly reachable from your http server.  This will be called the
-FAQDIR.  Create a subdirectory named RCS.  Make both the working
-directory and the RCS subdirectory wrld-writable.  (This is essential,
-since the FAQ wizard runs as use nobody, and needs to create
-additional files here!)
-
-Edit faqconf.py to reflect your setup.  You only need to edit the top
-part, up till the line of all dashes.  The comments should guide you
-in your edits.  (Actually, you can also choose to add your changes to
-faqcust.py and leave faqconf.py alone.  This is essential if you are
-maintaining multiple FAQs; see below.)
-
-Don't forget to edit the SECTION_TITLES variables to reflect the set
-of section titles for your FAQ!
-
-Next, edit faqw.py to reflect the pathname of your Python interpreter
-and the values for SRCDIR and FAQDIR that you just chose.  Then
-install faqw.py in your cgi-bin directory.  Make sure that it is
-world-executable.  You should now be able to connect to the FAQ wizard
-by entering the following URL in your web client (subsituting the
-appropriate host and port for "your.web.server", and perhaps
-specifying a different directory for "cgi-bin" if local conventions so
-dictate):
-
-	http://your.web.server/cgi-bin/faqw.py
-
-If you are unable to get this working, check your server's error_log
-file.  The documentation for Python's cgi module in the Python Library
-Reference Manual gives plentyu additional information about installing
-and debugging CGI scripts, including setup debugging.  This
-documentation is repeated in the doc string in the cgi module; try
-``import cgi; print cgi.__doc__''.
-
-Assuming this works, you should now be able to add the first entry to
-your FAQ using the FAQ wizard interface.  This creates a file
-faq01.001.htp in your working directory and an RCS revision history
-file faq01.001.htp,v in the RCS subdirectory.  You can now exercise
-the other FAQ wizard features (search, index, whole FAQ, what's new,
-roulette, and so on).
-
-
-Maintaining Multiple FAQs
--------------------------
-
-If you have multiple FAQs, you need a separate FAQDIR per FAQ, and a
-different customization file per FAQ.  The easiest thing to do would
-be to have the faqcust.py for each FAQ live in the FAQDIR for that
-FAQ, but that creates some security concerns, since the FAQDIR must be
-world writable: *if* someone who breaks into your system (or a
-legitimate user) manages to edit the faqcust.py file they can get
-arbitrary code to execute through the FAQ wizard.  Therefore, you will
-need a more complex setup.
-
-The best way is probably to have a directory that is only writable by
-you for each FAQ, where you place the copy of faqcust.py for that FAQ,
-and have a world-writable subdirectory DATA for the data.  You then
-set FAQDIR to point to the DATA directory and change the faqw.py
-bootstrap script to add FAQDIR/.. to sys.path (in front of SRCDIR, so
-the dummy faqcust.py from SRCDIR is ignored).

-framer is a tool to generate boilerplate code for C extension types.
-
-The boilerplate is generated from a specification object written in
-Python.  The specification uses the class statement to describe the
-extension module and any extension types it contains.  From the

+#!/usr/bin/python
+'''
+From gdb 7 onwards, gdb's build can be configured --with-python, allowing gdb
+to be extended with Python code e.g. for library-specific data visualizations,
+such as for the C++ STL types.  Documentation on this API can be seen at:
+http://sourceware.org/gdb/current/onlinedocs/gdb/Python-API.html
+
+
+This python module deals with the case when the process being debugged (the
+"inferior process" in gdb parlance) is itself python, or more specifically,
+linked against libpython.  In this situation, almost every item of data is a
+(PyObject*), and having the debugger merely print their addresses is not very
+enlightening.
+
+This module embeds knowledge about the implementation details of libpython so
+that we can emit useful visualizations e.g. a string, a list, a dict, a frame
+giving file/line information and the state of local variables
+
+In particular, given a gdb.Value corresponding to a PyObject* in the inferior
+process, we can generate a "proxy value" within the gdb process.  For example,
+given a PyObject* in the inferior process that is in fact a PyListObject*
+holding three PyObject* that turn out to be PyBytesObject* instances, we can
+generate a proxy value within the gdb process that is a list of bytes
+instances:
+  [b"foo", b"bar", b"baz"]
+
+Doing so can be expensive for complicated graphs of objects, and could take
+some time, so we also have a "write_repr" method that writes a representation
+of the data to a file-like object.  This allows us to stop the traversal by
+having the file-like object raise an exception if it gets too much data.
+
+With both "proxyval" and "write_repr" we keep track of the set of all addresses
+visited so far in the traversal, to avoid infinite recursion due to cycles in
+the graph of object references.
+
+We try to defer gdb.lookup_type() invocations for python types until as late as
+possible: for a dynamically linked python binary, when the process starts in
+the debugger, the libpython.so hasn't been dynamically loaded yet, so none of
+the type names are known to the debugger
+
+The module also extends gdb with some python-specific commands.

+C'est revenir tard, je le sens, sur un sujet trop rebattu et déjà presque oublié. Mon état, qui ne me permet plus aucun travail suivi, mon aversion pour le genre polémique, ont causé ma lenteur à écrire et ma répugnance à publier. J'aurais même tout à fait supprimé ces Lettres, ou plutôt je lie les aurais point écrites, s'il n'eût été question que de moi : Mais ma patrie ne m'est pas tellement devenue étrangère que je puisse voir tranquillement opprimer ses citoyens, surtout lorsqu'ils n'ont compromis leurs droits qu'en défendant ma cause. Je serais le dernier des hommes si dans une telle occasion j'écoutais un sentiment qui n'est plus ni douceur ni patience, mais faiblesse et lâcheté, dans celui qu'il empêche de remplir son devoir.
+Rien de moins important pour le public, j'en conviens, que la matière de ces lettres. La constitution d'une petite République, le sort d'un petit particulier, l'exposé de quelques injustices, la réfutation de quelques sophismes ; tout cela n'a rien en soi d'assez considérable pour mériter beaucoup de lecteurs : mais si mes sujets sont petits mes objets sont grands, et dignes de l'attention de tout honnête homme. Laissons Genève à sa place, et Rousseau dans sa dépression ; mais la religion, mais la liberté, la justice ! voilà, qui que vous soyez, ce qui n'est pas au-dessous de vous.
+Qu'on ne cherche pas même ici dans le style le dédommagement de l'aridité de la matière. Ceux que quelques traits heureux de ma plume ont si fort irrités trouveront de quoi s'apaiser dans ces lettres, L'honneur de défendre un opprimé eût enflammé mon coeur si j'avais parlé pour un autre. Réduit au triste emploi de me défendre moi-même, j'ai dû me borner à raisonner ; m'échauffer eût été m'avilir. J'aurai donc trouvé grâce en ce point devant ceux qui s'imaginent qu'il est essentiel à la vérité d'être dite froidement ; opinion que pourtant j'ai peine à comprendre. Lorsqu'une vive persuasion nous anime, le moyen d'employer un langage glacé ? Quand Archimède tout transporté courait nu dans les rues de Syracuse, en avait-il moins trouvé la vérité parce qu'il se passionnait pour elle ? Tout au contraire, celui qui la sent ne peut s'abstenir de l'adorer ; celui qui demeure froid ne l'a pas vue.
+Quoi qu'il en soit, je prie les lecteurs de vouloir bien mettre à part mon beau style, et d'examiner seulement si je raisonne bien ou mal ; car enfin, de cela seul qu'un auteur s'exprime en bons termes, je ne vois pas comment il peut s'ensuivre que cet auteur ne sait ce qu'il dit.

-This is release 1.2 of modulator, a generator of boilerplate code for

-
-Difference between 1.2 and 1.1: __doc__ templates are now generated
-(thanks to Jim Fulton).
-
-Difference between 1.1 and 1.0: the templates now use "new-style"
-naming conventions. Many thanks to Chak Tan <tan@ee.rochester.edu> for
-supplying them.
-
-Usage when you have tk is *really* simple: start modulator, fill out
-the forms specifying all the objects and methods, tell modulator
-whether objects should also be accessible as sequences, etc and press
-'generate code'. It will write a complete skeleton module for you.
-
-Usage when you don't have tk is slightly more difficult. Look at
-EXAMPLE.py for some details (to run, use "python EXAMPLE.py").  Don't
-bother with EXAMPLE.py if you have Tkinter!!!
-
-Oh yeah: you'll probably want to change Templates/copyright, or all

-"""checkappend.py -- search for multi-argument .append() calls.
-
-Usage:  specify one or more file or directory paths:
-    checkappend [-v] file_or_dir [file_or_dir] ...
-
-Each file_or_dir is checked for multi-argument .append() calls.  When
-a directory, all .py files in the directory, and recursively in its
-subdirectories, are checked.
-
-Use -v for status msgs.  Use -vv for more status msgs.
-
-In the absence of -v, the only output is pairs of the form
-
-    filename(linenumber):
-    line containing the suspicious append
-
-Note that this finds multi-argument append calls regardless of whether
-they're attached to list objects.  If a module defines a class with an
-append method that takes more than one argument, calls to that method
-will be listed.
-
-Note that this will not find multi-argument list.append calls made via a
-bound method object.  For example, this is not caught:
-
-    somelist = []
-    push = somelist.append
-    push(1, 2, 3)

-Webchecker
-----------
-
-This is a simple web tree checker, useful to find bad links in a web
-tree.  It currently checks links pointing within the same subweb for
-validity.  The main program is "webchecker.py".  See its doc string
-(or invoke it with the option "-?") for more defails.
-
-History:
-
-- Jan 1997.  First release.  The module robotparser.py was written by
-Skip Montanaro; the rest is original work by Guido van Rossum.
-
-- May 1999.  Sam Bayer contributed a new version, wcnew.py, which
-supports checking internal links (#spam fragments in URLs) and some
-other options.
-
-- Nov 1999.  Sam Bayer contributed patches to reintegrate wcnew.py
-into webchecker.py, and corresponding mods to wcgui.py and
-websucker.py.
-
-- Mar 2004.  Chris Herborth contributed a patch to let webchecker.py
-handle XHTML's 'id' attribute.

-"""GUI interface to webchecker.
-
-This works as a Grail applet too!  E.g.
-
-  <APPLET CODE=wcgui.py NAME=CheckerWindow></APPLET>
-
-Checkpoints are not (yet???  ever???) supported.
-
-User interface:
-
-Enter a root to check in the text entry box.  To enter more than one root,
-enter them one at a time and press <Return> for each one.
-
-Command buttons Start, Stop and "Check one" govern the checking process in
-the obvious way.  Start and "Check one" also enter the root from the text
-entry box if one is present.  There's also a check box (enabled by default)
-to decide whether actually to follow external links (since this can slow
-the checking down considerably).  Finally there's a Quit button.
-
-A series of checkbuttons determines whether the corresponding output panel
-is shown.  List panels are also automatically shown or hidden when their
-status changes between empty to non-empty.  There are six panels:
-
-Log        -- raw output from the checker (-v, -q affect this)
-To check   -- links discovered but not yet checked
-Checked    -- links that have been checked
-Bad links  -- links that failed upon checking
-Errors     -- pages containing at least one bad link
-Details    -- details about one URL; double click on a URL in any of
-              the above list panels (not in Log) will show details
-              for that URL
-
-Use your window manager's Close command to quit.
-
-Command line options:
-
--m bytes  -- skip HTML pages larger than this size (default %(MAXPAGE)d)
--q        -- quiet operation (also suppresses external links report)
--v        -- verbose operation; repeating -v will increase verbosity
--t root   -- specify root dir which should be treated as internal (can repeat)
--a        -- don't check name anchors
-
-Command line arguments:
-
-rooturl   -- URL to start checking
-             (default %(DEFROOT)s)
-
-XXX The command line options (-m, -q, -v) should be GUI accessible.
-
-XXX The roots should be visible as a list (?).
-
-XXX The multipanel user interface is clumsy.

-#! /usr/bin/env python
-
-# Original code by Guido van Rossum; extensive changes by Sam Bayer,
-# including code to check URL fragments.
-
-"""Web tree checker.
-
-This utility is handy to check a subweb of the world-wide web for
-errors.  A subweb is specified by giving one or more ``root URLs''; a
-page belongs to the subweb if one of the root URLs is an initial
-prefix of it.
-
-File URL extension:
-
-In order to easy the checking of subwebs via the local file system,
-the interpretation of ``file:'' URLs is extended to mimic the behavior
-of your average HTTP daemon: if a directory pathname is given, the
-file index.html in that directory is returned if it exists, otherwise
-a directory listing is returned.  Now, you can point webchecker to the
-document tree in the local file system of your HTTP daemon, and have
-most of it checked.  In fact the default works this way if your local
-web tree is located at /usr/local/etc/httpd/htdpcs (the default for
-the NCSA HTTP daemon and probably others).
-
-Report printed:
-
-When done, it reports pages with bad links within the subweb.  When
-interrupted, it reports for the pages that it has checked already.
-
-In verbose mode, additional messages are printed during the
-information gathering phase.  By default, it prints a summary of its
-work status every 50 URLs (adjustable with the -r option), and it
-reports errors as they are encountered.  Use the -q option to disable
-this output.
-
-Checkpoint feature:
-
-Whether interrupted or not, it dumps its state (a Python pickle) to a
-checkpoint file and the -R option allows it to restart from the
-checkpoint (assuming that the pages on the subweb that were already
-processed haven't changed).  Even when it has run till completion, -R
-can still be useful -- it will print the reports again, and -Rq prints
-the errors only.  In this case, the checkpoint file is not written
-again.  The checkpoint file can be set with the -d option.
-
-The checkpoint file is written as a Python pickle.  Remember that
-Python's pickle module is currently quite slow.  Give it the time it
-needs to load and save the checkpoint file.  When interrupted while
-writing the checkpoint file, the old checkpoint file is not
-overwritten, but all work done in the current run is lost.
-
-Miscellaneous:
-
-- You may find the (Tk-based) GUI version easier to use.  See wcgui.py.
-
-- Webchecker honors the "robots.txt" convention.  Thanks to Skip
-Montanaro for his robotparser.py module (included in this directory)!
-The agent name is hardwired to "webchecker".  URLs that are disallowed
-by the robots.txt file are reported as external URLs.
-
-- Because the SGML parser is a bit slow, very large SGML files are
-skipped.  The size limit can be set with the -m option.
-
-- When the server or protocol does not tell us a file's type, we guess
-it based on the URL's suffix.  The mimetypes.py module (also in this
-directory) has a built-in table mapping most currently known suffixes,
-and in addition attempts to read the mime.types configuration files in
-the default locations of Netscape and the NCSA HTTP daemon.
-
-- We follow links indicated by <A>, <FRAME> and <IMG> tags.  We also
-honor the <BASE> tag.
-
-- We now check internal NAME anchor links, as well as toplevel links.
-
-- Checking external links is now done by default; use -x to *disable*
-this feature.  External links are now checked during normal
-processing.  (XXX The status of a checked link could be categorized
-better.  Later...)
-
-- If external links are not checked, you can use the -t flag to
-provide specific overrides to -x.
-
-Usage: webchecker.py [option] ... [rooturl] ...
-
-Options:
-
--R        -- restart from checkpoint file
--d file   -- checkpoint filename (default %(DUMPFILE)s)
--m bytes  -- skip HTML pages larger than this size (default %(MAXPAGE)d)
--n        -- reports only, no checking (use with -R)
--q        -- quiet operation (also suppresses external links report)
--r number -- number of links processed per round (default %(ROUNDSIZE)d)
--t root   -- specify root dir which should be treated as internal (can repeat)
--v        -- verbose operation; repeating -v will increase verbosity
--x        -- don't check external links (these are often slow to check)
--a        -- don't check name anchors
-
-Arguments:
-
-rooturl   -- URL to start checking
-             (default %(DEFROOT)s)

-world -- Print mappings between country names and DNS country codes.
-
-Contact: Barry Warsaw
-Email:   bwarsaw@python.org
-
-This script will take a list of Internet addresses and print out where in the
-world those addresses originate from, based on the top-level domain country
-code found in the address.  Addresses can be in any of the following forms:
-
-    xx                -- just the country code or top-level domain identifier
-    host.domain.xx    -- any Internet host or network name
-    somebody@where.xx -- an Internet email address
-
-If no match is found, the address is interpreted as a regular expression [*]
-and a reverse lookup is attempted.  This script will search the country names
-and print a list of matching entries.  You can force reverse mappings with the
-`-r' flag (see below).
-
-For example:
-
-    %% world tz us
-    tz originated from Tanzania, United Republic of
-    us originated from United States
-
-    %% world united
-    united matches 6 countries:
-        ae: United Arab Emirates
-        uk: United Kingdom (common practice)
-        um: United States Minor Outlying Islands
-        us: United States
-        tz: Tanzania, United Republic of
-        gb: United Kingdom
-
-
- [*] Note that regular expressions must conform to Python 1.5's re.py module
- syntax.  The comparison is done with the search() method.
-
-Country codes are maintained by the RIPE Network Coordination Centre,
-in coordination with the ISO 3166 Maintenance Agency at DIN Berlin.  The
-authoritative source of counry code mappings is:
-
-    <url:ftp://info.ripe.net/iso3166-countrycodes>
-
-The latest known change to this information was:
-
-    Thu Aug  7 17:59:51 MET DST 1997
-
-This script also knows about non-geographic top-level domains.
-
-Usage: world [-d] [-p file] [-o] [-h] addr [addr ...]
-
-    --dump
-    -d
-        Print mapping of all top-level domains.
-
-    --parse file
-    -p file
-        Parse an iso3166-countrycodes file extracting the two letter country
-        code followed by the country name.  Note that the three letter country
-        codes and numbers, which are also provided in the standard format
-        file, are ignored.
-
-    --outputdict
-    -o
-        When used in conjunction with the `-p' option, output is in the form
-        of a Python dictionary, and country names are normalized
-        w.r.t. capitalization.  This makes it appropriate for cutting and
-        pasting back into this file.
-
-    --reverse
-    -r
-        Force reverse lookup.  In this mode the address can be any Python
-        regular expression; this is matched against all country names and a
-        list of matching mappings is printed.  In normal mode (e.g. without
-        this flag), reverse lookup is performed on addresses if no matching
-        country code is found.
