Any time you can avoid making specific version # checks, you're better 
off.  When I was dealing with Microsoft version changes, I frequently 
ran into problems where one piece of code would lie about versions just 
to fool certain libraries into compensating, and the resulting mess was 
a morass of bugs waiting to pop.  Remember when Windows 4.0 had an 
internal version of 3.99, so that some obscure package would still be 
willing to work?

try:
     input = raw_input
except NameError as e:
     pass

try:
     range = xrange
except NameError as e:
     pass
