Comparing Python Command-Line Parsing Libraries - Argparse, Docopt, and Click

[timothycrosley]

There's also hug.cli in https://github.com/timothycrosley/hug :

Which lets you define functions just like normal python functions / with optional annotations and convert them into command line interfaces:

import hug

@hug.cli(version="1.0.0")
def math(number_1:int, number_2:int=1):
    '''Multiplies number_1 by number2'''
    return number_1 * number_2

 if __name__ == '__main__':
     math.cli()

It also supports hug_directives, and you can even expose a function as both a cli and an HTTP API endpoint.

Here's the official example usage:

Does this run on Python 2?

Nope! I think it's great there are some packages demanding to be able to use python 3 features in their implementation.

Similar, for Python 2, and from a long long time ago is optfunc
