How do I switch my default Python version to Python 3 in Fedora 23?

edit

I am trying to switch my default Python version to Python 3, since that's what I primarily work in and if I don't, then several IDE's will freak out at me. I have no idea how to do this. Can I just rename Python 3 "python" and switch Python 2's name to "python2" if I want to run it, and if so, how?
