Expanding on Andrew Bennetts' answer, you typically do things like
this:

if sys.version_info[:2] >= (2, 2):
     print 'has 2.2 features in place'
elif sys.version_info[:3] == (1, 5, 2):
     print 'precisely version 1.5.2'

etc...

That is, use slices of version_info as desired, comparing with
constant tuples.
