Moving to Python 3.x

[Antranig Vartanian]

Hay,

I learned the basics of python using the book "Think Python" 
(http://www.greenteapress.com/thinkpython/) which was good (IMHO), and it 
teaches in Python 2.7. Now I'm trying to write my first python+gtk 
program.

anyways, my question will be, is it so necessary to move to python3.x 
ASAP? or Python2.7 will live for a while (2-3 years)?.

and what do you advice a newbie programmer to do after learning the 
basics?

Thanks all!
