<html><head></head><body>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<br>

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. <br>
<br>
New python projects should be with version 3, not 2.<br><br><div class="gmail_quote">On January 24, 2018 6:03:33 PM EST, Todor Fassl via Ale <ale@ale.org> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
