Hi Lance,

> but I'm also curious if RH7 will have Python3 or just stay on Python2.

RDO Train will be released at GA on RHEL7/CentOS7 on Python2, since
that's what was tested throughout this release cycle,
and as soon as we have CBS Koji ready for c8, we'll start
bootstrapping dependencies and move master (Ussuri) and Train to
EL8/py3
This work is tracked in

There are no plans to add python36 support on RHEL 7.7.
