How to use sets?
Hi Logan, Ah! I think you looking for the set() builtin, which was added in Python 2.4. But you're still using Python 2.3.4, when sets weren't "built in" yet. They're still accessible, but you have to do a module import in 2.3. You can make your example work by doing the following at the beginning: ### from sets import Set as set ### Best of wishes to you! _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
