Pick up the Learning Python book.
Strangely, I think this youtube lecture series from Stanford is fantastic. http://www.youtube.com/watch?v=KkMDCCdjyW8
It's java but the lecturer eases you into the most important concepts with an understanding of how to engineer readable, reusable code. So watch it free. Then buy Learning Python. If there is an equivalent python learning video on youtube, I haven't found it.
