이 모든 내용은 OpenAPI에 결합되어 포함되고, API 문서에 표시됩니다:

## 미리 정의된 응답과 커스텀 응답 결합하기 { #combine-predefined-responses-and-custom-ones }

여러 *경로 처리*에 적용되는 미리 정의된 응답이 필요할 수도 있지만, 각 *경로 처리*마다 필요한 커스텀 응답과 결합하고 싶을 수도 있습니다.

그런 경우 Python의 `dict` “unpacking” 기법인 `**dict_to_unpack`을 사용할 수 있습니다:

```Python
old_dict = {

所有这些都会被合并并包含到你的 OpenAPI 中，并显示在 API 文档里：

## 组合预定义响应和自定义响应 { #combine-predefined-responses-and-custom-ones }

你可能希望有一些适用于许多*路径操作*的预定义响应，但同时又想把它们与每个*路径操作*所需的自定义响应组合在一起。

在这些情况下，你可以使用 Python 的“解包”`dict` 的技巧 `**dict_to_unpack`：

```Python
old_dict = {
    "old key": "old value",

* `skip`，具有預設值 `0` 的 `int`。
* `limit`，選填的 `int`。

你也可以像在[路徑參數](path-params.md#predefined-values)中一樣使用 `Enum`。
