There are lots of differences between 2.6 and the just-released 3.1, but
opinions are split about which is better for learning: some people say
that you should learn 3.x first because it's the future of Python and
it's simpler/cleaner; others (including me) say you should learn 2.x
first because that's where the bulk of current code is and many 3rd-party
libraries have not yet been ported to 3.x.

In the end, it doesn't make a lot of difference, as long as you stick
with only 2.x or 3.x during your initial learning: the core Python
syntax changes very little between the 2.x and 3.x, and there are only
two critical differences that will hit you up-front:

* Python 2.x has ``print`` as a statement; 3.x has ``print()`` as a
function

* Python 2.x has 8-bit strings by default; 3.x uses Unicode and has no
way to access 8-bit strings except as byte arrays

You might want to bookmark this, though:
