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

Jun 15: Leung Ling-kit wore a yellow raincoat with an umbrella standing at Pacific Place Patio at 4:30. He wrote “Carrie Lam kills Hong Kong” & “Black Cops are cold blooded” on a banner and hang it at the building for everyone to see. Police and negotiators went but did not allow anyone to go near him. At 9:15pm, he jumped down. That was the beginning of the 2 million+1 people march the next day. People still commemorate him in Hong Kong to this day while countless of #HKPolice was standing by as if having a flower in hand can damage #nationalsecurity. This is the excuse they use to arrest people anyway. The laws that we having been fighting against, the extradition bill, national security law & article 23 are laws that criminalize thoughts. #leunglingkit#HongKongProtest#5demandnot1less#fightforfreedom#standwithhongkong
