Оператор pipe позволяет писать более компактный код, реализуя логику объединения данных (Union). Важно помнить, что его поведение зависит от контекста. Побитовые операции (логическое OR) result = 5 | 3 # 5 (0101) | 3 (0011) = 7 (0111) Самое главное - не путать с оператором or, это другое! Объединение множеств set_a = {1, 2, 3} set_b = {3, 4, 5} set_c = set_a | set_b # {1, 2, 3, 4, 5} set_c |= {5, 6} # {1, 2, 3, 4, 5, 6} Слияние словарей dict_1 = {"a": 1, "b": 2} dict_2 = {"b": 3, "c": 4} merged = dict_1 | dict_2 # {'a': 1, 'b': 3, 'c': 4} merged |= {"d": 5} # {'a': 1, 'b': 3, 'c': 4, 'd': 5} Аннотации типов, заменяет Union def process_data(value: int | str) -> None: print(value) Допустимо использовать в isinstance или issubclass isinstance(3, int | float) # True Паттерн-матчинг status_code = 404 match status_code: case 200 | 201 | 204: print("OK") case 400 | 404 | 500: print("ERROR") Для использования в своих классах требуется переопределить метод __or__ Так же нашел библиотеку pipe которая добавляет еще много возможностей. Рекомендую ознакомиться ;) #basic

Linus Torvalds 拒绝 Linux 6.17 的 RISC-V 更改，原因在于提交过晚且代码“垃圾” Linus Torvalds 拒绝了 Linux 6.17 内核的 RISC-V 架构更改，原因是提交时间过晚以及代码质量问题。此次变更的提交恰逢合并窗口即将关闭，且Torvalds本人正在旅行。Torvalds对其中包含的特定代码片段表示不满，将其描述为“垃圾”，特别指出了一段名为 make_u32_from_two_u16() 的辅助函数。Torvalds强调，这类低质量的代码不应出现在通用头文件中，并警告未来将不再接受迟到的合并请求或非 RISC-V 树中的垃圾代码。提交者回应将改进提交时间并关注质量问题。Slashdot 🏷#Linus#Torvalds#RISC#V#Linux 📢频道👥群组📝投稿

Vitalik Buterin proposes binary state trees and a RISC-V VM to solve Ethereum’s execution bottlenecks. ⚡️ 他指出，目前以太坊执行层面临两大核心瓶颈： 1️⃣ 状态访问与存储效率 2️⃣ 虚拟机架构限制 通过引入 Binary State Trees，有望优化状态证明结构，而 RISC-V 虚拟机 则可能提升执行效率与灵活性。 “A better VM can make Ethereum beautiful and great.” ⚡️这不仅是技术升级讨论，更是 长期可扩展性与模块化路线的关键一步。 若推进顺利，或将影响未来 L2 设计与执行层架构方向。 #Ethereum#ETH#Layer1#Scaling #Blockchain#EVM#RISC#Crypto
