lang/python/ PythonVersion3

Python2 is now legacy. Python3 is where it's at. On UbuntuLinux one can install a package {{python-is-python3}} which means {{/usr/bin/python}} points to {{/usr/bin/python3}} rather than {{/usr/bin/python2}}. I used to be a Ruby person, and didn't get into Python until Python3 was ready for serious use, and was recommended to beginners.
