首先要注意的是，我们定义了一个带有 `yield` 的异步函数。这与带有 `yield` 的依赖项非常相似。

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

这个函数在 `yield` 之前的部分，会在应用启动前执行。

剩下的部分在 `yield` 之后，会在应用完成后执行。

### 异步上下文管理器 { #async-context-manager }

如你所见，这个函数有一个装饰器 `@asynccontextmanager`。

它将函数转化为所谓的“**异步上下文管理器**”。

{* ../../docs_src/events/tutorial003_py310.py hl[1,13] *}

在 Python 中，**上下文管理器**是一个你可以在 `with` 语句中使用的东西，例如，`open()` 可以作为上下文管理器使用。

Only differences from the base Go toolchain defaults are reported.

When testing a package, `//go:debug` lines in the `*_test.go`
files are treated as directives for the test's main package.
In any other context, `//go:debug` lines are ignored by the toolchain;
`go` `vet` reports such lines as misplaced.
