Let's look at how we can make that work.

#### Випадковий елемент { #a-random-item }

За допомогою `data.items()` ми отримуємо <dfn title="Щось, що ми можемо ітерувати циклом for, як-от список, множина тощо.">ітерабельний об'єкт</dfn> із кортежами, що містять ключ і значення для кожного елемента словника.

Ми перетворюємо цей ітерабельний об'єкт у звичайний `list` за допомогою `list(data.items())`.

但如果你把同一個模型用作輸出，如下所示：

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py hl[19] *}

...由於 `description` 有預設值，就算你沒有為該欄位回傳任何內容，它仍會有那個預設值。

### 輸出回應資料的模型 { #model-for-output-response-data }

在互動式文件中試用並檢視回應時，儘管程式碼沒有為其中一個 `description` 欄位加入任何內容，JSON 回應仍包含預設值（`null`）：

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image02.png">
</div>

但如果你把同一个模型用作输出，例如：

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py hl[19] *}

...那么因为 `description` 有默认值，即使你**不返回该字段**，它仍然会有这个**默认值**。

### 输出响应数据的模型 { #model-for-output-response-data }

如果你在文档中交互并查看响应，即使代码没有给某个 `description` 字段赋值，JSON 响应中仍包含默认值（`null`）：

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image02.png">
</div>
