Question

I used Python a few years ago when 2 was the only version.

Now there is 2 and 3.

Was there a a reason 2 hasn’t continued to upgrade and now there is a split into two different pythons? Like no one uses Python 2.5. They all use 2.7 or whatever it is. Why not just use 3? Obviously there’s a reason, but I was unable to find it googling.

My second question is, which one should I use? I am assuming 3, but that’s ONLY based on the higher number. I wonder why 2 is still around if 3 is out??? If there aren’t any major bugs with 3, I am just going to use that as I don’t reckon it much matters: either one would probably work for py QT.

Answer 1

Why not just use 3?

A lot of existing Python code is not compatible with Python 3 yet. If you need to use Django for example you are forced to use Python 2.x.

My second question is, which one should I use?
