Current versions of Python on Debian Stable

[ode <ode5002@blueyonder.co.uk>]

I would like to run Python 2.7 and 3.2 on Debian stable. They are not in 
squeeze-backports. I would rather not install them from Unstable as I do 
not want a mixed system. Do I have to compile them myself or do you know 
of another trusted source that has backported them to Squeeze.

Many Thanks
