Python is a very interesting programming language. It's object-oritented, very high level, interpreted, and has a clean syntax.

The root of all things Python is http://www.python.org/. There are many links from that page to tutorials for people of all skill levels, including people who want to learn to program computers for the first time.

An interesting online book is http://diveintopython.net/ . It's geared toward programmers who want to learn Python.
