这有助于确保：

* 文档始终是最新的。
* 文档示例可以直接运行。
* 绝大多数特性既在文档中得以阐述，又通过测试覆盖进行保障。


### 应用和文档同时运行

如果你使用以下方式运行示例程序：

<div class="termy">

```console
$ uvicorn tutorial001:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

由于 Uvicorn 默认使用 `8000` 端口 ，因此运行在 `8008` 端口上的文档不会与之冲突。

Any other utility function that you call directly can be created with normal `def` or `async def` and FastAPI won't affect the way you call it.
