Sometimes it can be hard to fill an entire hour with a single subject (although I had the impression that we could have filled two with our VIM meetup). Maybe it's a good time for a lightning talk/demo meetup where members who have done cool things with python can put them on display in a 10-15 minute format.
I can do one on virtualenv:
Managing virtualenv across multiple servers: Virtualenv is used to create a sandbox for python to run inside that allows a set of specific packages and versions to be available. I can show you how to write a bash script that will install or update your virtualenv before calling the python prgram that will utilize it. I can also demonstrate how to have a python application automatically invoke and then run inside a virtualenv using pickle.
I don't see another planned meetup yet and this might be a nice way to keep them going without having to find someone that can dedicate an hour to a particular subject.
