There's a pattern I have developed for my python scripts of writing a object like that : # where a and b are functions FOO = { a.__name__: a, b.__name__: b } and with argparse do parser = argparse.ArgumentParser() parser.add_argument( "-f", "--foo", choices=FOO.keys(), default=next(iter(FOO)), help="choose your type of foo", )
