No need to feel bad about it :) Getting your head around "this is a function, that's where the function's being called" is not easy, and it takes experience. Your question was very well put. You provided a short, compact example that showcased the problem you were experiencing. That made it easy to answer your question. Keep on asking questions like that, please - you're helping yourself and making the mailing list a great place too :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
