Go for 3. Most Python 2 projects have plans or are in the process of transitioning, if that is keeping you back. Also, the two lines aren't as different as they used to be, as a lot of features get back-ported from 3 to 2. Python 3 is IMO a much cleaner and friendlier language to work with than 2. Especially if you're doing anything to do with Unicode, Python 2 can be a real pain. Also, all real development is now taking place on the 3.x series - if you want to keep up, you'd better learn it.
