Forget properties. Python is not Java or C++, and you almost never need this kind of thing. Read up a tutorial on doing classes Python's way, and you'll find that all this sort of thing just doesn't matter. You've come here with a significant number of questions about properties, and it looks as if you're trying to do everything through them - which is utterly and completely useless, especially when you use properties to be as dynamic as you're doing. Just don't do it. ChrisA
