I read Dive into Python and it's really good. Anybody interested in learning Python really should read it. Of course, the massive changes in Python 3 means that a lot of the old wisdom no longer works, so there's a need for a revise of this wonderful book.
I just found out that Dive into Python 3 will be out soon and it's once again an open source book. Good news for me since I'll be reading it. I never did find Dive into Python on the local bookshelves but hopefully I'll be able to find this new release.
