Look. 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.
