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

On the Schöningen Double-Pointed Sticks In Schöningen, Germany, archaeologists found double-pointed sticks, crafted 200,000 years ago by early Europeans, likely Neanderthals. These slender wooden tools, possibly throwing sticks, showcase precise craftsmanship. Sharpened at both ends, they reflect sophisticated woodwork and hunting skill. Their balanced design suggests aerodynamic mastery for small prey. Preserved in sediment, these artifacts highlight Europe’s ancient ingenuity. #artifacts @EuropeanTribalism

On swastikas (18) In 2020 scientists discovered a trove in Denmark, which contained around one kilogram of gold artifacts. Among these items there was a disc depicting the Norse god Odin. The interesting thing is, that this disc can be dated to the 5th century A.D., and is thus the oldest trace of Odin worship which was ever found. The runic inscription on the disc reads "He is Odin's man". Interestingly the swastika is clearly depicted next to Odins head in the center of the disc. #artifacts @EuropeanTribalism
