RHEL supports Python 3, it just doesn't provide Python 3. It almost 
certainly will work if you install from source. I haven't tried it on 
RHEL myself, but I have done so on Fedora and Centos, and there's no 
problem.

But be warned that you should not replace the system python with Python 
3. When installing, don't use "make install", as that will replace the 
system Python, instead use "make altinstall". Then the command "python" 
will still refer to the system Python (probably Python 2.4 or 2.5?), and 
"python3" should refer to Python 3.x.

You shouldn't be learning programming on a production server :)
