Часто всю функциональность использования асинхронного кода с `async` и `await` кратко называют «сопрограммами». Это сопоставимо с ключевой особенностью Go — «goroutines».

## Заключение { #conclusion }

Вернёмся к той же фразе:

> Современные версии Python поддерживают **«асинхронный код»** с помощью **«сопрограмм»** (coroutines) и синтаксиса **`async` и `await`**.

Теперь это должно звучать понятнее. ✨
