The Google TechTalks from March 14, 2007 is about Python Design Patterns. It’s very interesting stuff. Alex Martelli, famous book author (Python Cookbook, Python in a Nutshell) and Googler in Mountain View since 2005, presents his talk in the Advanced Topics in Programming Languages Series. You can see the two parts on Google Video. In addition there are 82 pages (pdf) for download from Martellis own website.
