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
