Here it is—a shiny new edition of Beginning Python. If you count its predecessor, Practical Python, this is actually the third edition, and a book I’ve been involved with for the better part of a decade. During this time, Python has seen many interesting changes, and I’ve done my best to update my introduction to the language. At the moment, Python is facing perhaps its most marked transition in a very long time: the introduction of version 3. As I write this, the final release isn’t out yet, but the features are clearly defined and working versions are available. One interesting challenge linked to this language.
