Dive Into Python 3

Mark Pilgrim's Dive Into Python 3 is a hands-on guide to Python 3 and its differences from Python 2. As in the original book, Dive Into Python, each chapter starts with a real, complete code sample, proceeds to pick it apart and explain the pieces, and then puts it all back together in a summary at the end. This book includes example programs completely rewritten to illustrate powerful new concepts now available in Python 3: sets, iterators, generators, closures, comprehensions, and much more. It also features a detailed case study of porting a major library from Python 2 to Python 3 and a comprehensive appendix of all the syntactic and semantic changes in Python 3. This is the perfect resource for you if you need to port applications to Python 3, or if you like to jump into languages fast and get going right away.
