Python Cookbook. A. Martelli, A. Ravenscroft, D. Ascher

So what exactly is a Python cookbook? It`s a collection of recipes for Python programmers, contributed by Python community members. The original contributions were made through a web site set up by ActiveState, from which a selection was made by editors Alex Martelli and David Ascher. Other Python luminaries such as Fredrik Lundh, Paul Dubois, and Tim Peters were asked to write chapter  Introductions.
