Detect Python Version

I was working on a distribution recently where python was mapped to python2. It mixed me up for a bit since I was writing a script for python3 but it ran partially under python2. To lower confusion in the future, I think it’s a great idea to check the python version and exit if it isn’t the version you expect.

from sys import version_info, exit

if version_info.major != 3:
    print("This script only supports Python 3")
    print("Curent version: " + \
          str(version_info.major) + "." + \
          str(version_info.minor) + "." + \
