what system is that? a mac? If so , the sadly you do have to get py3 yourself. If a Linux distro, then you likely already have python 3 preinstalled. `/usr/bin/python` won't point to python3 in anytime in the near future.
Haha it's Ubuntu. After I downloaded Python 3.6 last night, I found out I had Python 3.4 already on my machine. I got excited about new software and forgot to check. It's a crutch :/
