/// info | 情報

`Offer`は`Item`のリストであり、オプションの`Image`のリストを持っていることに注目してください。

///

## 純粋なリストのボディ

期待するJSONボディのトップレベルの値がJSON`array`（Pythonの`list`）であれば、Pydanticモデルと同じように、関数のパラメータで型を宣言することができます:

```Python
images: List[Image]
```

以下のように:

{* ../../docs_src/body_nested_models/tutorial008.py hl[15] *}

## あらゆる場所でのエディタサポート

///

## Тіла запитів, що складаються зі списків

Якщо верхній рівень JSON тіла, яке Ви очікуєте, є JSON `масивом` (у Python — `list`), Ви можете оголосити тип у параметрі функції, як і в моделях Pydantic:

```Python
images: List[Image]
```
або в Python 3.9 і вище:

```Python
images: list[Image]
```
