Just wanted to make a quick post to mention that the 3rd Edition revision is going well. I've completed about 2/3 of the book and hope to have it done by the end of the year. With reviews, editing, and finalizing, it should be available before next spring.
This is an extensive rewrite, incorporating changes readers have mentioned and adding new material as the Python language has evolved. I'm also going to include practice questions so the book can be used more like a textbook, as well as a primer and reference.
If there is anything special you'd like me to cover, please post it in the comments.
