Well, if you're just starting, learns ZPT now, not DTML...

You're setting the attribute of a _class_ in a method. Go ask on 
comp.lang.python why that's bad, but, the quick answer is just DON'T DO IT!

as a concept is very simple (hence why everyone loves it), the implementation is 
often very complex... think about form submission, and one-way state transitions...
