## Example { #example }

### Create it { #create-it }

Create a file `main.py` with:

```Python

Y puedes declarar dependencias con `async def` dentro de *path operation functions* normales `def`, o dependencias `def` dentro de *path operation functions* `async def`, etc.

No importa. **FastAPI** sabrá qué hacer.

`async def`을 사용하거나 혹은 일반적인 `def`를 사용할 수 있습니다.

그리고 일반적인 `def` *경로 작동 함수* 안에 `async def`로 의존성을 선언할 수 있으며, `async def` *경로 작동 함수* 안에 `def`로 의존성을 선언하는 등의 방법이 있습니다.

아무 문제 없습니다. **FastAPI**는 무엇을 할지 알고 있습니다.

Package zip provides support for reading and writing ZIP archives.

See the [ZIP specification] for details.

This package does not support disk spanning.

A note about ZIP64:

To be backwards compatible the FileHeader has both 32 and 64 bit Size
fields. The 64 bit fields will always contain the correct value and
for normal archives both fields will be the same. For files requiring

     * same class realm is used to load build extensions and load mojos for extensions=true plugins.

即，既可以使用异步的 `async def`，也可以使用普通的 `def` 定义依赖项。

在普通的 `def` *路径操作函数*中，可以声明异步的 `async def` 依赖项；也可以在异步的 `async def` *路径操作函数*中声明普通的 `def` 依赖项。

上述这些操作都是可行的，**FastAPI** 知道该怎么处理。

/// note | 笔记

如里不了解异步，请参阅[异步：*“着急了？”*](../../async.md){.internal-link target=_blank} 一章中 `async` 和 `await` 的内容。

## 与 OpenAPI 集成

依赖项及子依赖项的所有请求声明、验证和需求都可以集成至同一个 OpenAPI 概图。

所以，交互文档里也会显示依赖项的所有信息：
