I'm new to python world. I started to use https://www.pythonanywhere.com and at some point if asks me to select python version which I want:
Select a Python version
» Python 2.7
» Python 3.4
» Python 3.5
» Python 3.6
» Python 3.7
For me this is similar to:
What hammer do you want to hit this nail? Version "oldest", "newer", "the newest"?
Of course "the newest"! Why would I use some old crap?
So (unless there are some compatibility mater in my nail to be hit) why would I want to use an old version of python?
