sys.argv is filled in from the command line arguments.  Perhaps
 your script should protect itself by majing sure len (sys.argv)
 is what's required,  in this case at least 2.  That way the user
 gets a friendlier message when he omits the arguments.

By the way, you should simply copy/paste the entire stack trace.
 When you paraphrase,  you're likely to have a typo, or omit
 something useful.
