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

📖Gallup: Gen Z Reassesses AI Use Amid Growing Concerns A Gallup report based on a survey of nearly 1,600 U.S. respondents aged 14–29 shows declining enthusiasm for AI among Gen Z, alongside rising negative sentiment. Only 18% reported feeling hopeful and 22% excited about AI, down from 27% and 36% the previous year, while 31% expressed anger, up from 22%. Anxiety levels remained stable at around 40%. Despite growing skepticism, AI use continues: over half of respondents reported using AI at least weekly, though adoption growth has slowed. Nearly half of Gen Z workers believe the risks of AI in the workplace outweigh the benefits, even as 56% say it improves efficiency. Eight in ten respondents indicated that reliance on AI may negatively affect learning outcomes, while around half expect AI to be necessary for education and future careers. #AIRegulation#AIethics#FutureOfWork#Education#AIsociety

🚀 AI TRENDS | OpenAI's Sam Altman Addresses AI Development Concerns and Recent Incident OpenAI founder Sam Altman has expressed understanding of societal fears regarding the rapid development of artificial intelligence. According to Odaily, Altman acknowledged that the current period is marked by significant technological change, with associated risks escalating to systemic challenges at the societal level. He emphasized that AI power should not be concentrated in a few institutions and advocated for broader distribution through technological democratization and institutional constraints. Addressing a recent incident where his residence was targeted with a Molotov cocktail, Altman admitted to underestimating the impact of public narratives and emotions amid AI-related anxieties. He also acknowledged mistakes in company governance and conflict management, offering apologies for past actions. Furthermore, Altman reiterated his decision to reject Elon Musk's attempts to control OpenAI, ensuring the company's independent development. Previously, it was reported that the OpenAI founder's residence was attacked with a Molotov cocktail. #AI#OpenAI#SamAltman#AIdevelopment#technologicalchange#AIsociety#democratization#institutionalconstraints#Molotovcocktail#publicnarratives#conflictmanagement#ElonMusk#companygovernance#independence
