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。

```Python
with open("file.txt") as file:
    file.read()
```

Python 的最近几个版本也有了一个**异步上下文管理器**，你可以通过 `async with` 来使用：

```Python
async with lifespan(app):
    await do_stuff()
```

你可以像上面一样创建了一个上下文管理器或者异步上下文管理器，它的作用是在进入 `with` 块时，执行 `yield` 之前的代码，并且在离开 `with` 块时，执行 `yield` 后面的代码。

但在我们上面的例子里，我们并不是直接使用，而是传递给 FastAPI 来供其使用。
