Ранее я уже упоминал о другой фишке из ˍˍfutureˍˍ , это оператор деления.
from __future__ import division
Суть проста. Раньше сложность типа данных результата поределялась типом самого сложного операнда.
Например:
int/int => int
int/float => float
В первом случае оба операнда int, значит и результат будет int. Во втором float более сложный тип, поэтому результат будет float.
Если нам требуется получить дробное значение при делении двух int то приходилось форсированно один из операндов конверировать в float.
12/float(5) => float
Но с новой "философией" это не требуется. В Python3 "floor division" заменили на "true division" а старый способ теперь работает через оператор "//".
>>> 3/2
1.5
>>> 3//2
1
То есть теперь деление int на int даёт float если результат не целое число.
В классах теперь доступны методы __floordiv__() и __truediv__() для определения поведения с этими операторами.
Данный переход описан в PEP238.

Smile is the only curve that sets things in straight line.
Harsh from Gujarat pens down a thought on smile...!!
Do you know what's satisfying?
When you make someone smile while they were crying.
That smile which holds fire to shine from within, But helplessness just dims their light within.
The smile that wants to burst out laughing,
But their situation insists them to shed another drop of tear.
We can just take a small initiative.
Don't show hatred towards anyone in their low
You never know, when that low might turn everything around.
If possible bring a smile on someone's face
The satisfaction you'll gain can't be expressed.
God's above seeing this, will smile too
And in your life you'll surely ace.
