Not really, though a growing market is good. The OS system tools are in 
Python 2 so that's what is installed. Nothing prevents an application 
from installing Python 3, it just can't overwrite the OS python.

Application developers can put Python 3 in /usr/local or can use one of 
the probably older python3 rpm stacks. My dev box has both the OS Python 
2.6.6 and Python 3.6.2 called as python3.
