(Mostly for my own mental health)
Starting with Python, current is 3.3.3, so I'll stick with that for duration of project if possible.
For rev/scm, I'll start w/ git, since it's used at work and is pretty much the de-facto standard.
Hosting - bitbucket. (Free personal, option to switch to mercurial)
This ties in nicely as I like Sourcetree as my client for either.
Editor/IDE will probably be (free Community edition) PyCharm
