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

#Ethiopia: Report warns of arbitrary detentions, growing restrictions on media in Addis Ababa ------- A new report by Human Rights First has raised concerns over alleged arbitrary detentions and increasing restrictions on media in #Addis_Ababa, particularly during periods of major international events. The report, titled “Situational Analysis of Human Rights in Addis Ababa,” states that security forces carried out “pre-emptive detentions” across several parts of the capital without due process. According to the findings, detentions were recorded in sub-cities including #Yeka, #Bole, and #Akaki_Kality, where individuals were held for more than a week without being charged or appearing before court. In addition, the report highlighted what it described as a growing pattern of restrictive actions against media between 2025 and early 2026. Read more: https://addisstandard.com/?p=55925

News: Report tracks #UAE-linked cargo flights to #Ethiopian military base amid regional power struggle A cargo aircraft previously linked to the supply of weapons to armed groups in #Sudan has conducted multiple flights to Ethiopia in recent weeks, according to an exclusive investigation by the UK-based outlet Middle East Eye (MEE), raising questions about Ethiopia’s role in intensifying regional rivalries tied to the war in Sudan. MEE reported that an Antonov An-124 cargo plane operated by UAE-based Maximus Air, and allegedly linked to Emirati military logistics, made repeated flights between #Abu_Dhabi and #Harar_Meda airbase, the main base of the Ethiopian Air Force. Flight-tracking data reviewed by the outlet shows at least four trips to Harar Meda between 3 and 17 January, including one flight that later continued to Addis Abeba’s #Bole International Airport before departing for #Europe and #Asia. While the purpose of the flights remains unclear... Read more: https://addisstandard.com/?p=54681
