The two most common uses of it are: When add_argument() is called with action='store_const' or action='append_const'.

The original point of the discussion was in fact about using alternative quotes to avoid alternate backslashes (or at least excessive ones). https://bytes.com/topic/python/answers/803203-newbie-help-typeerror-int-argument-required This object has a single method, add_parser(), which takes a command name and any ArgumentParser constructor arguments, and returns an ArgumentParser object that can be modified as usual. The Action class must accept the two positional arguments plus any keyword arguments passed to ArgumentParser.add_argument() except for the action itself. With the 'store_const' and 'append_const' actions, the const keyword argument must be given.

To change this behavior, see the formatter_class argument. Creating a parser¶ The first step in using the argparse is creating an ArgumentParser object: >>> parser = argparse.ArgumentParser(description='Process some integers.')

When it's finished, the query will actually say, "...WHERE price < 5". I still remember when I started programming, I wrote in QBASIC without indentations. A single optional argument --foo that should be followed by a single command-line argument will be referred to as FOO. his comment is here 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,

The supported values are: N (an integer). N arguments from the command line will be gathered together into a list. 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 parse_args() is called, optional arguments will be was indented weird ... I find it odd that you consider qquoting less scalable than backslashes.

This is commonly useful for command line utilities that dispatch to other command line utilities: >>> parser = argparse.ArgumentParser(prog='PROG') >>> parser.add_argument('--foo') >>> parser.add_argument('command') >>> parser.add_argument('args', nargs=argparse.REMAINDER) >>> print(parser.parse_args('--foo B cmd --arg1 epilog¶ Some programs like to display additional description of the program after the description of the arguments. The nargs keyword argument associates a different number of command-line arguments with a single action. prog¶ By default, ArgumentParser objects use sys.argv[0] to determine how to display the name of the program in help messages.
