Newbie python version choice?

Question

Python

I want to start learning this language, I ran into the problem of choosing a version. Everywhere they write 3.4 raw and many libraries do not work. I work on Linux OS with python on board 2.7.4. Question to knowledgeable people, which version to use? I would like to learn to program in python from the console to the GUI, as network support is also important.

Answer 1

2016 is about to start soon. It's time to consider the third python as the default python.
Yes, there are several libraries that do not work under the third python, but almost all of them have a replacement.

Answer 2

Python 3.4+ and asyncio rule. Not enough scrapy, but it will come out someday
