Те, кто в Python не первый день, хорошо знают, что на число можно умножить не только число, но и другие типы. Главное, чтобы у этих типов была реализация такой операции. # list >>> [1] * 3 [1, 1, 1] # tuple >>> (2, 3) * 3 (2, 3, 2, 3, 2, 3) # string >>> "A" * 3 "AAA" Так работает полиморфизм стандартных типов. Интересно здесь то, что это сработает и в том случае, когда порядок операндов обратный. То есть int умножить на [тип]. # list >>> 3 * [1] [1, 1, 1] # tuple >>> 3 * (2, 3) (2, 3, 2, 3, 2, 3) # string >>> 3 * "A" "AAA" Если хотите реализовать такое поведение в ваших классах то следует помнить два момента: 1. Если множитель справа, то вам нужно реализовать метод __mul__, наш класс это первый операнд, то есть слева. myType * 3 2. Если множитель слева, то вам нужно реализовать метод __rmul__, наш класс это второй операнд, справа. 3* myType Всё тоже самое можно делать и для других математических операторов. И если в этом примере действие и результат будут фактически одинаковыми, то бывают ситуации, когда это не так. Например, при умножении матриц имеет значение порядок операндов. Для других операторов, таких как деление или сдвиг, очень важно кто с какой стороны находится. >>> 2/4, 4/2 (0.5, 2.0) >>> 2<<3, 3<<2 (16, 12) >>> 100%15, 15%100 (10, 15) #tricks#basic

@RusEmbMalta Press release 🛑The “Register of Damage” and the So-Called Claims Commission: A Dangerous Legal Mirage The Russian Federation expresses serious concern over the ongoing attempts to promote the so-called “Register of Damage” and the related International Claims Commission for Ukraine (ICC) – initiatives that openly contradict international law and threaten to undermine the very foundations of the global legal order. 📌 As the Russian Foreign Ministry has repeatedly stressed, these structures are not genuine legal mechanisms, but politically motivated constructs designed to fabricate financial claims against Russia and to create informational justification for the illegal seizure of sovereign Russian assets. ⚖️Pseudolegal Tools Disguised as Justice According to the official statement of the Russian Foreign Ministry (26 September 2025), the proposed Claims Commission – currently being pushed through the Council of Europe – is intended to: • legitimize politically motivated accusations, • artificially calculate “compensation,” • and provide cover for the confiscation of Russian assets frozen in the West. Such actions constitute gross violations of international law and amount to nothing less than state-sponsored expropriation. 💰A Risky Scheme for Those Who Join The European Commission’s attempts to dress these actions up as a “reparations mechanism” have already alarmed a number of EU member states. Even senior European officials have openly warned that these plans expose participating countries to massive legal, financial and reputational risks. The danger is obvious: any state that associates itself with these mechanisms becomes a direct party to a hostile act and assumes serious exposure to future legal and economic consequences. 🌍An Appeal to Responsible States We call on all responsible members of the international community – not to allow themselves to be drawn into this politically charged and legally void project. This campaign is not about justice. It is about expanding geopolitical pressure, prolonging the conflict, and sabotaging any genuine diplomatic settlement. Those who value international law must not lend legitimacy to instruments that openly violate it. ________ ✋ The Russian Federation firmly urges governments to refrain from joining or endorsing the “Register of Damage” and the so-called International Claims Commission. 📍 Participation in these initiatives does not serve peace, law, or stability – it only deepens global fragmentation and legal chaos. ________ #InternationalLaw#RegisterOfDamage#ClaimsCommission#RuleOfLaw#StopTheScam
