I see that I haven't been on this site since last August. However, I have a good excuse: I've been writing a new Python book for a publisher. The book is now going to the printers, so I have some time to get back here.
The book is titled Secrets of the Python Ninja, from Packt Publishing. The book will actually be available June 11, but pre-orders are available at Amazon right now. It has over 70 walk-throughs of a variety of Python features, both in the standard library and third party tools.
