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.

Jesse Derry was taken to hospital as a precaution following his first-half substitution during today’s #PL game against Nottingham Forest.
Jesse is conscious, talking and undergoing precautionary checks. We wish him a speedy recovery and thank the medical staff for their swift response.
Steve Holland:
“Our last game, Bournemouth to Leeds, is a #PL record, I think, in terms of time between games.
“So the gap has been as big as you can have really. I think we felt it was important to get the whole group together again, and really focus on finishing the season well.
“I think this is the PERFECT venue for that, really.”
Steve Holland:
“I think the language we should be using as this club is to finish as CLOSE as we possibly can to the top [this season].
“I don’t know how possible that is, but that has to be the challenge always: to get as close as we possibly CAN to the top...” [MU]
Bruno Fernandes on matching Cristiano Ronaldo’s #PL POTM record:
“It’s always good company. We know when records are there, his name will always be around.
“It’s a HUGE honour and privilege to be close to him.” 🇵🇹❤️
