오류에는 정확히 어느 지점에서 검증을 통과하지 못했는지 명시됩니다.

이는 API와 상호 작용하는 코드를 개발하고 디버깅하는 데 매우 유용합니다.

## Documentation

Et quand vous vous rendez sur <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>, vous verrez la
documentation générée automatiquement et interactive :

/// info

* Designed around these standards, after a meticulous study. Instead of an afterthought layer on top.
* This also allows using automatic **client code generation** in many languages.

### Automatic docs { #automatic-docs }

Interactive API documentation and exploration web user interfaces. As the framework is based on OpenAPI, there are multiple options, 2 included by default.

{* ../../docs_src/path_operation_configuration/tutorial004_py310.py hl[17:25] *}

It will be used in the interactive docs:

## Response description { #response-description }

You can specify the response description with the parameter `response_description`:

### Revisa la documentación

Ahora puedes iniciar tu aplicación e ir a <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

Verás tu documentación incluyendo una sección de "Callbacks" para tu *path operation* que muestra cómo debería verse la *API externa*:

    # o documentOutputDirectory: (NotRequired - Default './output/doc')
    #  The output directory mainly for SchemaHtml and DataXlsTemplate.
    #  Basically you don't need this.
    #  It is considered of value that it always exists at same plain.
    #
    #; documentOutputDirectory = ./output/doc
    # - - - - - - - - - -/

    # /- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

So, the line:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

will not be executed.
