We just scratched the surface, but you already get the idea of how it all works.

Try changing the line with:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...from:

```Python
        ... "item_name": item.name ...
```

...to:

```Python
        ... "item_price": item.price ...
```

    * 檢查是否有必填屬性 `name`，且為 `str`。
    * 檢查是否有必填屬性 `price`，且為 `float`。
    * 檢查是否有可選屬性 `is_offer`，若存在則應為 `bool`。
    * 以上也適用於深度巢狀的 JSON 物件。
* 自動在 JSON 與 Python 之間轉換。
* 以 OpenAPI 記錄所有內容，可用於：
    * 互動式文件系統。
    * 為多種語言自動產生用戶端程式碼的系統。
* 直接提供兩種互動式文件網頁介面。

我們只觸及了表面，但你已經了解它的運作方式了。

試著把這一行：

```Python
    return {"item_name": item.name, "item_id": item_id}
```

All container images are available as manifest lists and support the described
architectures. It is also possible to pull a specific architecture directly by
adding the "-$ARCH" suffix  to the container image name.

Например, модель выше описывает такой JSON "`object`" (или Python `dict`):

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...так как `description` и `tax` являются необязательными (со значением по умолчанию `None`), такой JSON "`object`" тоже будет корректным:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

### Использование имени *функции-обработчика пути* как operationId { #using-the-path-operation-function-name-as-the-operationid }

Если вы хотите использовать имена функций ваших API в качестве `operationId`, вы можете пройти по всем из них и переопределить `operation_id` каждой *операции пути* с помощью их `APIRoute.name`.

Делать это следует после добавления всех *операций пути*.
