`dict`의 키가 또 다른 `dict`인 각 예제와 값을 구별합니다.

각각의 특정 `examples` 속 `dict` 예제는 다음을 포함할 수 있습니다:

* `summary`: 예제에 대한 짧은 설명문.
* `description`: 마크다운 텍스트를 포함할 수 있는 긴 설명문.
* `value`: 실제로 보여지는 예시, 예를 들면 `dict`.
* `externalValue`: `value`의 대안이며 예제를 가르키는 URL. 비록 `value`처럼 많은 도구를 지원하지 못할 수 있습니다.

이를 다음과 같이 사용할 수 있습니다:

{* ../../docs_src/schema_extra_example/tutorial005_an_py310.py hl[23:49] *}

**FastAPI** will use that *temporal* response to extract the cookies (also headers and status code), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

You can also declare the `Response` parameter in dependencies, and set cookies (and headers) in them.

## Return a `Response` directly { #return-a-response-directly }

    /**

because it doesn't include the already stored attribute `"tax": 20.2`, the input model would take the default value of `"tax": 10.5`.

And the data would be saved with that "new" `tax` of `10.5`.
