Comment The goal is modern, supported, popular tools? (Score 1) 325
If you're switching from LabView to Python because it's an open, popular, well-supported language that's easy to find experienced programmers for, I can't recommend learning anything other than git for version control. SVN works, yes, and lots of people have previous experience with it, yes, but git is ubiquitous and there are lots of excellent tutorials that should have your team up and running on it in less than an hour. My biggest difficulty in moving from SVN to git was not git, but rather un-learning SVN and the assumptions and mindset needed to use it effectively.
There's the added bonus of finding extremely inexpensive ($25/month) git hosting (GitHub) for private teams of unlimited size.
