While poking around, I stumbled across this site and found the information to be pretty darn good. It's a Google class on Python taught by Nick Parlante of Stanford (and Google apparently.) There are videos, all materials, exercises--the works.
I found it helpful to go through (I'm somewhat self-taught) and it undid some bad habits and showed me some stuff I'd missed along the way. Can't beat the price of admission.
