I have use Click for some years now.
Has some strong features that other tool in this category may lack.
Quick demo of sorting some input from command line.

import click

@click.command()
@click.option('-q', '--quick', type=str, help='Sort text input')
def my_sort(quick):
    lst = list(quick)
    lst = sorted(lst)
    click.echo(''.join(lst))

if __name__ == '__main__':
   my_sort()

Usage command line:

Output:
λ my_sort --quick 9593912358439
1233345589999

λ my_sort -q 94567phron230hdrt9931
012334567999dhhnoprrt

λ my_sort --help
Usage: my_sort [OPTIONS]

Options:
  -q, --quick TEXT  Sort text input
  --help            Show this message and exit.

See that can call my_sort without python or .py
As Click has good Setuptools Integration.

from setuptools import setup

setup(
    name='my_sort',
    version='0.1',
    py_modules=['my_sort'],
    install_requires=[
        'Click',
    ],
    entry_points='''
        [console_scripts]
        my_sort=my_sort:my_sort
    ''',
)
