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

Hong Kong Democracy Movement

The calendar of this year’s June is exactly like the one 5 years ago. June 16th, was a Father’s Day, but it wasn’t a time for celebration. Instead, millions of families came out to protest against a bill that would destroy the #ruleoflaw. Everyone in the city knew that in order to maintain the city’s order and status, the bill needed to be revoked. However, the Chief Executive of Hong Kong at the time, Carrie Lam, was arrogant enough not to respond. The government even transform the city into a #PoliceState, organized #TerroristAttack on July21, and #Police randomly attacking regular citizens on Aug31. Now, look at the city, what has it become? Dropping its ranking in every single criteria. Even judges resigned saying that Hong Kong is becoming a #totalitarianstate. This is 1 of many brilliant cities the #CCP destroys.
