Python 3 has the advantage of having a future. It is the living branch of the language. The advantage of Python 2 is an evaporating pool of legacy Python2-only libraries and legacy Python2-only programmers. Python2 is dying at the rate that pool is evaporating. Python 3 has the advantage of having a future, plus all the advantages of Python 2 and more with the exception of that shrinking pool. I have already replaced all my Python 2 code and won't intentionally write more code that I know will have to be replaced. I'd like anything I build now to have the greatest likelihood of still being something I can continue building on in the future. Python 3 is more likely to fit that requirement than Python 2. I'm teaching my kids to program. Python 3 is a good choice for doing so. Python 2 would set them up to be teenage maintenance programmers. Doing that to them would be child abuse. I upgrade my own skills, too, so wouldn't choosing Python 2 for my own upgrades be a form of self-abuse?
