[Tutor] Python 2 vs Python 3

[Danny Yoo]

Hi Ratheeshkumar,

It probably makes the most sense to switch to Python 3; Python 3 was
meant to have fewer idiosyncrasies than Python 2, and should be easier
to learn.

There is a document that summarizes the Python 2 -> Python 3 changes.
It's here: https://docs.python.org/3/whatsnew/3.0.html.  You can find
more information at: https://wiki.python.org/moin/Python2orPython3.

But I think you probably want to use Python 3, unless you have a
legacy reason for it.  And as a beginner, those legacy reasons should
be minimal for you.  :P
