Here is an example for quick reference. argv holds the program name at index 0. That's why we start at 1.

#!/usr/bin/python

import sys

def main():
    # print command line arguments
    for arg in sys.argv[1:]:
        print arg

if __name__ == "__main__":
    main()

Try it out:

$ python cmdline_args.py arg1 arg2 arg3
arg1
arg2
arg3
