І відповідь з кодом статусу `200`, яка використовує ваш `response_model`, але містить власний `example`:

{* ../../docs_src/additional_responses/tutorial003_py310.py hl[20:31] *}

Усе це буде поєднано та включено до вашого OpenAPI і показано в документації API:

E um retorno com o código de status `200` que utiliza o seu `response_model`, porém inclui um `example` customizado:

{* ../../docs_src/additional_responses/tutorial003_py310.py hl[20:31] *}

Isso será combinado e incluído em seu OpenAPI, e disponibilizado na documentação da sua API:

<img src="/img/tutorial/additional-responses/image01.png">

例如，你可以宣告一個狀態碼為 `404` 的回應，使用一個 Pydantic 模型，並帶有自訂的 `description`。

以及一個狀態碼為 `200` 的回應，使用你的 `response_model`，但包含自訂的 `example`：

{* ../../docs_src/additional_responses/tutorial003_py310.py hl[20:31] *}

以上都會被結合並包含在你的 OpenAPI 中，並顯示在 API 文件：
