The Book of Python is a complete reference to the Python programming language. It begins with a discussion of Python's programming environment (data types, packages, and modules), then moves on to more advanced topics, including object oriented programming, interacting with operating systems, creating GUIs and database interfaces, network programming, XML, and web programming. Functions and modules are cross-referenced throughout and multiple examples illustrate how to use Python. The authors have extensive experience with large scale, mission critical Python applications-real world experience that forms an unusually solid foundation for a book of this sort.
