- Python and Eclipse
- version control
The installation of these two tools is pretty easy under windows and mac. I currently use the python version 2.6 and the appropriate pygame version. I want to recommend Eclipse as an IDE, for which you can get the addon PyDev from the official page or the Eclipse Marketplace (available in all Eclipse versions except "Classic") to comfortably write python scripts ;). The next Eclipse Addons, which I use are a better XML-editor (e.g. Rhinzo XML editor) and eGit.
