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.

🚘 Skytop with "the most powerful V8 engine ever" unveiled
The latest BMW Skytop has made its debut at the Villa d'Este 2024 classic car show on the shores of Lake Como.
The two-seater car has a rigid roof that can be removed manually and the rear window can be raised and lowered with a button. "Chrome shadow effect" is designed specifically for the Skytop.
According to the manufacturer, the car has been given the "most powerful V8 engine", which is supposedly the same 4.4-litre 625bhp engine used in the M8 Competition.
In creating the Skytop, BMW decided to pay homage to the brand's classic models such as the Z8 and 503. Although the car is only a concept car at the moment, BMW has not ruled out the possibility of a limited production run.
