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

https://code.tutsplus.com/tutorials/beginning-test-driven-development-in-python--net-30137 Test-driven development (#TDD) is a process that has been documented considerably over recent years. A process of baking your tests right into your everyday coding, as opposed to a nagging afterthought, should be something that developers seek to make the norm, rather than some ideal fantasy. I will introduce the core concepts of TDD.

http://index-of.es/Python/Foundations.of.Agile.Python.Development.Jeff.Younker.2008.pdf What Is Agile Development? #Agile development is a term given to an entire class of iterative development methodologies. Their unifying characteristic is a focus on short development cycles, on the scale of weeks rather than months. Each development cycle, referred to as an iteration or sprint, produces a working product. #TDD#test

https://www.obeythetestinggoat.com/pages/book.html#toc "Test-Driven Web Development with Python" aims to teach #TDD for web programming. It uses a concrete example — the development of a website, from scratch — to explain the TDD metholology and how it applies to building web applications. It covers the #Selenium browser-automation tool, #unit_testing, mocking, and interacting with Web technologies from the basics of static content, database integration, throught the inescapable JavaScript, and onto more advanced (and trendy) topics like #NoSQL, #websockets and Async programming.
