I suggest you read the other thread you started. And getting more specific, don't try to do everything on one line. Factor out the logic so you can test each part independently. And add comments describing what each line is trying to do. That way, you'll have a chance of figuring out why things aren't working. After it all works, if you're trying to impress someone, you can squeeze it down to one cryptic line again. -- DaveA _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
