你也可以将其定义为常规函数而不使用 `async def`:

```Python hl_lines="7"
{!../../../docs_src/first_steps/tutorial003.py!}
```

!!! note
    如果你不知道两者的区别，请查阅 [Async: *"In a hurry?"*](https://fastapi.tiangolo.com/async/#in-a-hurry){.internal-link target=_blank}。

### 步骤 5：返回内容

```Python hl_lines="8"
{!../../../docs_src/first_steps/tutorial001.py!}
```

你可以返回一个 `dict`、`list`，像 `str`、`int` 一样的单个值，等等。
