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

#Kashkadarya Spring is the breath of nature, the heartbeat of our land. When fields are covered with scarlet tulips, it feels as if the earth itself has dressed in festive colors… 🌺 Yet sadly, there are those who, instead of admiring this beauty, consider destroying it a “heroic” act. A video circulating on social media shows a car with the license plate 70 R418XA and two other vehicles driving over fields of tulips, crushing not only the flowers but also the insects and reptiles that live there. What is most disturbing is that they record this cruelty with laughter and a sense of “pride”… This is not just a violation. This is violence against nature. This is a clear manifestation of moral degradation. Tulips are not just flowers. They are a symbol of spring, a vital part of the ecosystem, and a habitat for thousands of living beings. Destroying them means breaking an entire chain of life. The exact location of the incident is unknown, but based on the license plate, it is likely that it took place in the Kashkadarya region. In this regard, we call on the Kashkadarya Regional Department of Ecology to provide a legal assessment of this incident and hold those responsible accountable under the law. Nature does not belong to us. We are only its guests. If we fail to protect beauty, we will fail to protect the future… 🌍 ☘️Read the latest environmental news on the @ekologuz page.
