Welcome to Google's Python Class -- this is a free class for people with a little bit of programming experience who want to learn Python. The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience.
This book describes Python, an open-source general-purpose interpreted programming language. Python has distributions available for Microsoft Windows, Apple Mac OS X, GNU/Linux, BSD, web browser environments (NCLab, Sage) and many other platforms. There are currently three major implementations: the standard implementation written in C, Jython written in Java, and IronPython written in C# for the .NET environment.
