argparse.py

import argparse

parser = argparse.ArgumentParser()

parser.add_argument("--argument_one", help="This argument does nothing")
parser.add_argument("--argument_two", help="This argument is even more useless than other one.")

parsed = parser.parse_args()  # By default, this uses sys.argv. 
                              # This means the arguments doesnt have to be coming from CLI.

print parsed.__dict__
