I would still stick with python 2.
In my opinion there is no reason to rush to the most recent version.
Especially when working in a corporate environment or when being obliged
to use certain web servers / servers you will notice, that
you will still encounter quite some hosts with python 2.5 and even some
with python2.4.
Most machines, that I have to use, run python 2.6 (and some python
2.5) I personally try to write most of my code such that it could still
run with python 2.5 I decided that python2.4 is my cut-off point,
though I still have one machines and some embedded devices, which just
run 2.4
Other considerations
- there are still more libraries / packages available for python
2 than for python 3, though this is changing.
- if you write code nicely enough in python 2, then you can translate it
to python 3. autmatically. However up to my knowledge you
cannot automatically translate python 3 code to python 2 code.
With that strategy your code will be able to run on most web servers and
your own machines.
If you want to write your own code which does not have to run on other
machines and / or if you want to heavily use unicode, then it might be
better to start with Python 3.
