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

ATTENTION! Nominations for the Her Abilities Award are now open! We are seeking nominations of incredible women with disabilities from around the globe in three categories: Health & Education; Rights; Arts, Culture & Sports. This year, the Award takes on a special significance. 2020 has seen catastrophic bush fires in Australia, the global COVID19 pandemic, and the rise of the Black Lives Matter movement, uniting people worldwide against racism and police violence. Women with disabilities have been a part of it all. Whether on the front lines or ploughing a quiet furrow for progress. Their situation means they often face extra danger. Yet their stories are too seldom heard. Do you know a woman with a disability who has achieved excellence? Help us celebrate #herabilities! You have until 27th September to nominate. More info is available on the Her Abilities Award website www.her-abilities-award.org #HerAbilities#EU4HumanRights#EU4Women
