Here's an argparse example: $ cat argparse_list.py import argparse parser = argparse.ArgumentParser() parser.add_argument("-m", "--modus", type=int, nargs="*") print parser.parse_args().modus $ python argparse_list.py None $ python argparse_list.py -m [] $ python argparse_list.py -m 1 [1] $ python argparse_list.py -m 1 2 3 [1, 2, 3] -- http://mail.python.org/mailman/listinfo/python-list
