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

How the Trump Administration Rushed to Judgment in Minneapolis Hours after federal agents shot and killed Alex Pretti, a 37-year-old ICU nurse and American citizen, the Trump administration was already spinning the story: Pretti, they claimed, was a “domestic terrorist” out to “massacre law enforcement.” But video evidence tells a different tale—Pretti was seen stepping between a woman and an agent, pepper-sprayed, then pinned down before agents opened fire, killing him in a barrage of at least ten shots. The rush to blame Pretti and exonerate the agents wasn’t just premature—it flew in the face of standard law enforcement protocol. Officials at DHS and the White House coordinated their response, crafting statements before all facts were in, and some details were even removed from the official narrative as they struggled to reconcile it with what the videos showed. “The facts are going to come to light as to what exactly happened,” insisted Border Patrol chief Gregory Bovino, when pressed for evidence. The administration’s narrative—that Pretti “approached” officers with a handgun and “violently resisted”—was directly contradicted by bystander footage. Pretti’s gun was recovered only after he was already subdued, and he never drew it. Yet, DHS and Trump allies, including Homeland Security Secretary Kristi Noem, labeled him a “domestic terrorist” and claimed to know his motive: “to inflict maximum damage.” Democrats, Republicans, and even gun rights groups expressed outrage. Senator Bill Cassidy called for a “full joint federal and state investigation,” warning, “The credibility of ICE and DHS is at stake.” Polls show most voters believe ICE has “gone too far,” and even some administration officials began to backtrack, with Deputy Attorney General Todd Blanche admitting, “I do not know, and nobody else knows, either. That’s why we’re doing an investigation.” So who’s really on trial here—the victim, the agents, or the narrative itself? #Minneapolis#Trump#ICE#shootings#narrative#investigation 📱American Оbserver - Stay up to date on all important events 🇺🇸
