Awesome free Python class!

This class by Nick Parlante trumps most of the programming lectures I've attended in college!

What you get:

• Video recorded two day lectures that introduces Python and you require just the most basic of programming knowledge e.g. variables, if statement & loops.
• Good exercises that help you comfortably practice what you've just learnt.
