Coursera

Coursera has several Python-focused classes which we've heard good things about.

• An Introduction to Interactive Programming in Python (Part 1)
• Learn to Program: The Fundamentals
• Programming for Everybody

For those who aren't complete beginners:

• Crafting Quality Code
• Machine Learning
• MIT 600.1x

Coursera classes work well with study groups since the regular schedule helps keep you on track (and self-accountable!), plus you can meet others taking the same class. It's sometimes good to hear that you weren't the only one bashing your head against a particular assignment!
