Python or python 3?

Question

I want to learn python but I'm not sure if i need to learn first python before pass to python 3, or it's better start with python 3 instead

Answer 1

Python 2.x is no longer developed. Start learning Python 3, instead. Backward compatibility is easy and still you will learn something which is not dead :)

Answer 2

Use Python 3.5.X. This is the latest version of Python.
