If you're interested in Python, you won't want to miss the 
7th June 2012 class as David Billsbrough and Steve Litt's material on
"Introduction to the Python" programming language. David will delve
into the benefits of using Python as well as how to write excellent
Python. Steve will delve into writing object oriented Python, 
specifically: "How to make classes, how to instantiate objects from
those classes, and a tiny bit about inheritance and "what's the deal
with private variables."
