Create a new 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.
    • -
  • version - A version number used to add a -v/–version option to the parser.
  • 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.

    -

    Programs which want to display the program version at the command line can supply a version message as the version= argument to ArgumentParser. This will add a -v/--version option to the ArgumentParser that can be invoked to print the version string:

    -
    >>> parser = argparse.ArgumentParser(prog='PROG', version='%(prog)s 3.5')
->>> parser.print_help()

    Note you can use the %(prog)s format specifier to insert the program name into the version string. For greater customization, see the documentation on the 'version' action available for add_argument().
