I've made the switch on the code I write at work from Python 2 to Python 3, and it was far less of a hassle than I feared. Unless you're using a package that doesn't work on Python 3 (which isn't the case for me; NumPy, SciPy, pandas, scikit-learn, etc, all work fine on 3) or worrying a lot about Unicode, it isn't that difficult (in my experience) to write code that is compatible with both 2 and 3.
