Don't worry, I'm not going to put out another version so soon after making this one available. However, I would like some input from readers on what they would like to see in the next version, whenever I get ready to write it.
I've been thinking about adding a section about web programming, using either Django (which I haven't used yet, so it would be a good reason to learn) or Karrigell (which is a great web framework that is very easy to use). I think more expansion of GUI programming would be helpful as well, such as including screen shots and more discussion of GUI libraries.
I also don't know if rewriting the book to focus on Python 3.x would be good. It would relegate Python 2.x to a single chapter, much like the reverse of the book as it is now. People who are just starting in Python will most likely be using Python 3, but the installed Python version of *nix systems is usually an older version. Also, there is a lot of code in the wild that doesn't work with newer versions.
If you have an opinion about what to include, remove, or otherwise change in the next book version, please let me know.
