I am learning Python, and using PyQt to develop a GUI that will be used

working with a fairly recent Python version, 2.5.4. I've now become
aware of the existence of Python 3.1, which apparently is a major
revision of the language. Does it make sense to stick with Python 2.x at
this point, or should I be starting off with 3.1? If it is recommended
to stick with version 2, should I use the latest (2.6.4 or 2.7), and if
so why? Thanks.
My view is that if PyQt works with 3.1 (I have the impression it does
but may be wrong) and that is the only 3rd parth library you need, or
anything else you need works with 3.1, then strongly consider 3.1 for
new code. The main difference between 2.6 and 3.1 is the number of old,
obsolete things removed that you will not even be tempted to learn about.

On balance I think I'll stick with 2.x - another factor I didn't mention is that
most end-users will probably not have 3.x installed on their machines.
