In case that helps with the decision making process:
Debian 5.0 (lenny - no longer supported): py 2.5
Debian 6.0 (squeeze - current oldoldstable): py2.6
Debian 7.0/8.0/9.0 (wheezy/jessie/stretch - currently
oldstable/stable/testing): py2.7
So even this very conservative Linux distribution is supporting py2.7
for the past two years (and with the backporting branch I assume even
squeeze supports 2.7 which would make it a supported platform for the
pat 4 years on that distribution).
