/usr/bin/python is right now guaranteed to be the latest Python 2 and
/usr/bin/python3 is pointing to the latest Python 3. As I understand it,
there are no plans to repoint /usr/bin/python to Python 3, because that would
break application's expectations. I am aware that other distributions do this,
though, so you might need to autodetect what you are dealing with in this
case (e.g. through `python --version').
