This was posted on XSIBase a few weeks ago-ish. I bought the material and watched it and am thoroughly impressed. It explains concepts very clearly and shows many examples. The author also walks you through building a few python tools from start to finish. I would recommend a more simplistic intro to python before this tutorial however.
Overall I give it a 4 out of 5.
Python resources for 3d pros is slim but this one is worth the money.
