That's a strong question... Knowing OOP well is important, and it's often a good way to program, etc. But... You may try to rewrite your code with functions only and no classes (well, you may need to use classes for the TK gui). Feel free to not follow this suggestion of mine. Even if you follow it, it will not damage your brain :-) Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
