Saad, please don't send HTML emails, as it destroys the essential

arguments = sys.argv[1:]  # get the list of command line arguments
if arguments:
    # There are some.
    process(arguments)
else:
    # There are no arguments.
    do_something_else()



Or if you prefer, check that len(sys.argv) > 1.
