"""Docstring for the example.py module.
Modules names should have short, all-lowercase names. The module name may
have underscores if this improves readability.
Every module should have a docstring at the very top of the file. The
module's docstring may extend over multiple lines. If your docstring does
extend over multiple lines, the closing three quotation marks must be on
a line by itself, preferably preceded by a blank line.
"""
import os # standard library imports first
# Do NOT import using *, e.g. from numpy import *
#
# Import the module using
#
# import numpy
#
# instead or import individual functions as needed, e.g
#
# from numpy import array, zeros
#
# If you prefer the use of abbreviated module names, we suggest the
# convention used by NumPy itself::
import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
# These abbreviated names are not to be used in docstrings; users must
# be able to paste and execute docstrings after importing only the
# numpy module itself, unabbreviated.
def foo(var1, var2, *args, long_var_name="hi", only_seldom_used_keyword=0, **kwargs):
r"""Summarize the function in one line.
Several sentences providing an extended description. Refer to
variables using back-ticks, e.g. `var`.
Parameters
----------
var1 : array_like
Array_like means all those objects -- lists, nested lists, etc. --
that can be converted to an array. We can also refer to
variables like `var1`.
var2 : int
The type above can either refer to an actual Python type
(e.g. ``int``), or describe the type of the variable in more
detail, e.g. ``(N,) ndarray`` or ``array_like``.
*args : iterable
Other arguments.
long_var_name : {'hi', 'ho'}, optional
Choices in brackets, default first when optional.
Returns
-------
type
Explanation of anonymous return value of type ``type``.
describe : type
Explanation of return value named `describe`.
out : type
Explanation of `out`.
type_without_description
Other Parameters
----------------
only_seldom_used_keyword : int, optional
Infrequently used parameters can be described under this optional
section to prevent cluttering the Parameters section.
**kwargs : dict
Other infrequently used keyword arguments. Note that all keyword
arguments appearing after the first parameter specified under the
Other Parameters section, should also be described under this
section.
Raises
------
BadException
Because you shouldn't have done that.
See Also
--------
numpy.array : Relationship (optional).
numpy.ndarray : Relationship (optional), which could be fairly long, in
which case the line wraps here.
numpy.dot, numpy.linalg.norm, numpy.eye
Notes
-----
Notes about the implementation algorithm (if needed).
This can have multiple paragraphs.
You may include some math:
.. math:: X(e^{j\omega } ) = x(n)e^{ - j\omega n}
And even use a Greek symbol like :math:`\omega` inline.
References
----------
Cite the relevant literature, e.g. [1]_. You may also cite these
references in the notes section above.

expert systems and adaptive co-kriging for environmental habitat

and neural-network techniques," Computers & Geosciences, vol. 22,
pp. 585-588, 1996.
Examples
--------
These are written in doctest format, and should illustrate how to
use the function.
>>> a = [1, 2, 3]
>>> print([x + 3 for x in a])
[4, 5, 6]
>>> print("a\nb")
