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

#html The International Obfuscated C Code Contest (IOCCC) is a programming contest where participants write the most confusing and hard-to-understand C code, often under 512 bytes. It started in 1984 to highlight bad coding styles and show how poor structure can ruin a program. The contest uses satire to teach programmers about C’s tricky parts and the importance of clear coding by showing what not to do. Winning entries are both educational and entertaining, helping you learn subtle C language details while having fun. The contest encourages you to explore and understand complex code, improving your programming skills and appreciation for good style. https://github.com/ioccc-src/winner

#html You can easily create a secure Octra blockchain wallet by running a simple webserver on your computer. Just clone the wallet generator from GitHub, start the server, and open your browser to generate a new wallet. The tool shows your mnemonic phrase, private and public keys, and address, lets you test signatures, derive addresses for different networks, and automatically saves your wallet file. This helps you safely manage your Octra blockchain assets with full control over your keys and easy access to wallet features without needing complex setups. It’s a user-friendly way to secure and use your Octra wallet locally. https://github.com/octra-labs/wallet-gen

Is Skia the works-everywhere feature-rich text rendering engine I’ve always been looking for? It seems to work on all sorts of platforms, even on #HTML Canvas with WebAssembly (!) It even used to have particles support, but was sadly removed from 2 months ago. https://skia.org/ 🐘
