Right! This is not something that needs OOP! Besides, I find this belief that inside a class everything goes completely wrong. In that case you could write your code with globals and do whatever, then wrap it in a class, make your globals to be properties and voilá, every thing's all right. I don't think that is the way to go. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
