"Floor division" is the default in Python 2 (without "from __future__ 
import division"), but in Python 3, "true division" is the  default and 
there is a new "floor division" operator.

Python 2:

4 / 5 == 0
4.0 / 5 == 0.8

Python 3:

4 / 5 == 0.8
4 // 5 == 0

Project Jupyter <https://en.wikipedia.org/wiki/Project_Jupyter> provides 
a rich set of tools and supports Python.

Kind regards,
