Presentation software for Python code

[Michael Hoffman]

I mean to give a presentation next week to my workgroup on good Python 
programming practice. Last time I did a Python presentation I used 
PowerPoint which was not totally well-suited for the task. In 
particular, formatting code snippets was a pain, and they weren't even 
prettyprinted.

Does anyone here have software they would suggest for making a 
presentation that includes Python code? Other than that it would 
probably be mainly bullet points. I'm willing to consider TeX- and 
HTML-based approaches.
