如果你需要在异步函数里调用阻塞代码，或在阻塞函数里调用异步函数，可以使用 [Asyncer](https://asyncer.tiangolo.com)，它是 FastAPI 的姐妹库。

### `yield from` { #yield-from }

当你在迭代某个对象（例如类文件对象），并为每个条目执行 `yield` 时，你也可以使用 `yield from` 直接产出每个条目，从而省去 `for` 循环。

这并不是 FastAPI 特有的功能，只是 Python 的语法，但这是一个值得知道的小技巧。😎

### Функция lifespan { #lifespan-function }

Первое, на что стоит обратить внимание, — мы определяем асинхронную функцию с `yield`. Это очень похоже на Зависимости с `yield`.

{* ../../docs_src/events/tutorial003_py310.py hl[14:19] *}

Первая часть функции, до `yield`, будет выполнена до запуска приложения.

А часть после `yield` будет выполнена после завершения работы приложения.
