Отдельно разберём TaskGroup, который пришел на замену gather в Python 3.11. Ключевые отличия ▫️create_task() возвращает объект asyncio.Task, у которого есть соответствюущие методы управления. То есть у нас больше контроля ▫️это контекстный менеджер, который гарантирует что все таски будут остановлены по выходу из контекста ▫️ошибка автоматически отменяет незавершенные задачи, ▫️except* передает нам ExceptionGroup, в котором каждую ошибку можно обработать отдельно import asyncio import random async def do_it() -> str: if random.random() < 0.1: raise ValueError('Oops') delay = random.uniform(0.5, 1.5) await asyncio.sleep(delay) return delay async def main(): try: async with asyncio.TaskGroup() as tg: for _ in range(10): tasks.append(tg.create_task(do_it())) for t in tasks: print(t.result()) except *ValueError as e: for err in e.exceptions: print(err) asyncio.run(main()) Рекомендую изучить страницу Coroutines and Tasks из документации, где представлено больше интересных примеров и механизмов - таймауты - отмена задач - создание задач из другого потока #async

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.
