Before anyone comments that you can write a function for the points system, which was helpful to me when I asked a question regarding that very chapter: The book doesn't deal with functions until Chapter 6. As for your problem, Alan; I believe Alan already answered it -- you have two different lists, attributes and points, but a dictionary would be easier to handle. Not to say that it couldn't be done the way you're doing it though. A dictionary is built with key:value pairs. Then it's just about figuring out a way to change the value associated with each key when the attribute changes. I don't want to spoil the challenge of working it out yourself, but when I asked I was told to check out how values() and sum() worked. best regards, Robert S. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
