I have posted PythonToolbox, a list of modules and resources that I use quite often with Python. It includes modules that I commonly use for database access, markup, XML input/output, templating, searching, and classification. It also has a section on resources that I always seem to be turning to. Russ also helped out by adding some additional resources.
As always, it’s a wiki page, so if there’s something that you think should be in my PythonToolbox, feel free to add it. Enjoy!
