## Створіть свою модель даних

Потім ви оголошуєте свою модель даних як клас, який успадковується від `BaseModel`.

Використовуйте стандартні типи Python для всіх атрибутів:

```

////

//// tab | Python 3.10+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.

///

```Python hl_lines="6-7"
{!> ../../docs_src/dependencies/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.

///

```Python hl_lines="8-11"

## Определение полей содержащих списки

Вы можете определять атрибут как подтип. Например, тип `list` в Python:

//// tab | Python 3.10+

```Python hl_lines="12"
{!> ../../docs_src/body_nested_models/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="14"
{!> ../../docs_src/body_nested_models/tutorial001.py!}
```

////

////

//// tab | Python 3.10+ без Annotated

/// tip | "Подсказка"

Рекомендуется использовать версию с `Annotated` если возможно.

///

```Python hl_lines="7"
