`Offer`’ın bir `Item` list’i olduğuna, `Item`’ların da opsiyonel bir `Image` list’ine sahip olduğuna dikkat edin.

///

## Sadece list olan body’ler { #bodies-of-pure-lists }

Beklediğiniz JSON body’nin en üst seviye değeri bir JSON `array` (Python’da `list`) ise, tipi Pydantic modellerinde olduğu gibi fonksiyonun parametresinde tanımlayabilirsiniz:

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

şu örnekte olduğu gibi:

///

## Тіла запитів, що складаються зі списків { #bodies-of-pure-lists }

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]
```

наприклад:

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

as in:

{* ../../docs_src/body_nested_models/tutorial008_py310.py hl[13] *}

## Editor support everywhere { #editor-support-everywhere }

And you get editor support everywhere.

Even for items inside of lists:
