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.

The Dead Rabbit pregnancy test injected a woman’s urine into a female rabbit. If the rabbit’s ovaries changed, she was pregnant. The rabbit was always killed to check. People wrongly thought the rabbit died only if pregnant, thus creating the euphemism "the rabbit died" to say someone was pregnant.
This outdated but effective test killed many rabbits before kinder tests were made.

The UK government has unveiled an unprecedented plan to gradually eliminate animal testing in medical and pharmaceutical research.
The first phase will begin at the end of 2026 and will eliminate tests on mice used to develop treatments for skin and eye irritations.
Additionally, the country has committed to reducing the use of dogs and primates in laboratories by 35% by 2030, fulfilling an election promise made by the Labour Party.
Backed by £60 million, the strategy aims to promote ethical and technologically advanced alternatives that replace animal models without compromising the safety of vaccines, medicines, or pesticides.
Although animal experiments peaked in 2015 — with over 4 million animals used — advances in alternative methods had already helped reduce that number.
However, progress has stalled in recent years, so this new initiative seeks to accelerate the full replacement of animals.
Science Secretary Patrick Vallance stated, “Nobody wants to witness animal suffering,” and the new roadmap will allow governments, companies, scientists, and animal welfare organizations to collaborate on faster and more effective solutions.
Part of the investment will go to a specialized center that will integrate technology, data, and expertise to accelerate the transition to animal-free science.
🐾 Do you think Uzbekistan should implement a similar plan to reduce and replace animal testing? 🇺🇿💭
