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

In the wake of the Minneapolis Catholic church shooting, senior Justice Department officials are weighing proposals to limit transgender people’s right to possess firearms, according to two officials familiar with the internal discussions. The talks, described as preliminary in nature, appear to build on an idea that has gained some currency in conservative media since the Minneapolis shooting that killed two children and injured 21, most of them children, at Annunciation Catholic Church, an attack that police say was carried out by a 23-year-old transgender woman. Such a move would represent a dramatic escalation of the Trump administration’s fight against the rights of transgender Americans. President Donald Trump has issued a series of executive orders on the topic, including one barring transgender people from serving in the military and another ordering federal prisons to move transgender inmates to facilities corresponding to their gender assigned at birth. In addition, the idea of restricting gun rights has long been a red line for conservatives, with many Republican lawmakers and gun rights groups opposing red flag laws and or other policies aimed at keeping guns away from people suffering from mental health issues. But Justice Department leadership is seriously considering whether it can use its rulemaking authority to follow on to Trump’s determination to bar military service by transgender people and declare that people who are transgender are mentally ill and can lose their Second Amendment rights to possess firearms, according to one Justice official. Another senior Justice Department official cautioned that any such proposal, should it gain steam, would likely run into legal complications. Millions of Americans have mental health issues and many take medications, but are not a danger to society and therefore cannot have their rights infringed upon. #DOJ#transgenders#firearms 👂More on Trump's Ear ⚠️
