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.

Vegan diets can help the environment, but large-scale plant farming can hurt soil, wildlife, and cause pollution. Synthetic fertilizers used in farming can damage oceans and soil. Animal farming done the right way helps soil, supports wildlife, and uses natural manure. Eating animal foods gives important nutrients like B12 and iron that plants don’t provide.

A single tree, called the Tree of 40 Fruits, holds the record for the most varieties of fruit on one tree. Created by Sam Van Aken, it has 40 different types of stone fruits. These include peaches, plums, apricots, almonds, and cherries. The tree was made using grafting, where branches from different fruit trees are attached to one rootstock. This project shows how diverse fruit can grow on a single tree.

Hussam Saraf set a record for the most species grafted onto a single tree. His tree has 5 different species: plum, apricot, almond, peach, and cherry. The tree was made by grafting branches from these species onto one trunk. This represents diversity and peaceful coexistence, as the fruits symbolize how different cultures can live together.
