[ale] Slightly OT: System default python version

[Jim Kinney]

Rhel, and centos, still use python 2.7 as system default. Python 3.4 is optional. Most of the system management is python 2.7.  Fedora ships with both 2.7 and 3.6

Lot's of python 2 code can work in 3. But there's enough changes that it can't be relied upon to work without modifications. 

New python projects should be with version 3, not 2.
