Python tutorials http://anandology.com/python-practice-book/object_oriented_programming.html This is a good one....but it gets too deep too fast. This is the best thing I have read so far to help me understand classes. What I would like to see is more examples of computing before starting on drawing examples. I have to practice the first few steps of a dance before trying the whole thing.
For anyone here that might have an interest in making tutorials, using something useful as an example instead of using foo and bar helps me a lot towards understanding the concept too. -- https://mail.python.org/mailman/listinfo/python-list
