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. #pep#2to3#basic

📹 Russia's Foreign Minister Sergey #Lavrov’s video address to participants in the Moscow Nonproliferation Conference Key talking points: • The arms control, disarmament and #nonproliferation system crisis reflects unprecedented degradation in the sphere of international security. • The #West is balancing on the dangerous edge of a direct military confrontation between nuclear powers, which could have catastrophic consequences. • The US-led collective West is cynically complementing the deliberate destruction of balanced and equal agreements that do not suit Washington with the promotion of apparently dishonest schemes that would create advantages for the United States. • Striving to attain decisive military superiority, Washington and its allies are enlarging the network of alliances directed against other countries. They are working energetically to implement a number of highly destabilising military-technical programmes. • There is no basis whatsoever for an arms control and strategic stability dialogue with the United States in the face of a total hybrid war being waged against our country. • Moves to undermine the existing arms control and non-proliferation system are affecting the stability of the Treaty on the Non-Proliferation of Nuclear Weapons (https://disarmament.unoda.org/wmd/Nuclear/npt/text). <...> The Western countries have used the treaty for years to address political agendas unrelated to nuclear non-proliferation. • The attempts of the Western countries to tailor the OPCW to their vested interests are a source of serious concern. The Western states have already turned this prestigious and strictly technical international agency into an instrument for implementing their geopolitical interests in the Middle East and beyond by privatising the OPCW Secretariat. • We are convinced that to prevent further degradation of the world situation <...> all countries should pool their efforts to upgrade the international security system relying on the principles of multilateralism, equality and indivisibility. 🔗Read in full: https://mid.ru/en/foreign_policy/news/1945334/
