The Personal Distributed Information Store (PDIS) project at the Helsinki Institute for Information Technology has released a couple really nice utilities for Python on Series 60:
pyexpat for Series 60 "This is a port of the expat XML parser to Python for Series 60 enabling the standard Python xml package to be used in Python applications running on Series 60 phones."
Series 60 Compatibility Library "This is a wxPython-based implementation of some of the user interface toolkit APIs defined by Python for Series 60. It enables running many Python for Series 60 scripts on the desktop. The present version only supports Mac OS X."
