ArgumentParser.add_argument_group(title=None, description=None) By default, 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 add_argument_group() method: >>> parser = argparse.ArgumentParser(prog='PROG', add_help=False) >>> group = parser.add_argument_group('group') >>

ArgumentParser.exit(status=0, message=None) This method terminates the program, exiting with the specified status and, if given, it prints a message before that.

ArgumentParser.add_subparsers([title][, description][, prog][, parser_class][, action][, option_string][, dest][, help][, metavar]) 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. ArgumentParse

All parameters should be passed as keyword arguments. Each parameter has its own more detailed description below, but in short they are: prog - The name of the program (default: sys.argv[0]) us

any(iterable) Return True if any element of the iterable is true. If the iterable is empty, return False. Equivalent to: def any(iterable): for element in iterable: if element: return True return False

class argparse.Action(option_strings, dest, nargs=None, const=None, default=None, type=None, choices=None, required=False, help=None, metavar=None)

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 co

aifc.writeframesraw(data) Like writeframes(), except that the header of the audio file is not updated. Changed in version 3.4: Any bytes-like object is now accepted.
