Hi, If you like programming problems and reading about/creating
solutions to tasks in many languages not just Python, then take a look
at Rosetta Code: http://www.rosettacode.org . If you 'lurk' for a
while and read the submissions of others to get a feal for the site,
then their is a list of tasks
PyQt: http://www.riverbankcomputing.co.uk/software/pyqt/intro
All the benefits of Qt: multiplataform, excellent documentation, great
API, visual widget designer, etc, etc.
For the coding itself, I use netbeans + python plugin.
