Python 3 vs Python 2.7 dilemma

[Jorge Romero]

I would recommend you going on the Python 2.x path.

Python 2.x is far from being deprecated. According to Wesley Chun (active
member of Python community and author of Core Python Programming) on a
Google I/O talk, everybody will be using Python 3 by 2018, so there's still
plenty of time. Besides, you can start with Python 2.7, which still is 2.x
but introduces 3.x features, and in some benchmarks seems to be more
efficient than latest 3.x.

3.x is said to be backwards incompatible, but that incompatibility is not
something that would bring you a limitation on porting your code later.

So, for the sake of web frameworks and runtime infrastructures, I'd stick to
2.x.

This is my IMHO, I'm sure you can get a more accurate answer from someone in
this list more experienced in the matter ;)

Have a good one.
