## Создание вашей собственной модели

После этого вы описываете вашу модель данных как класс, наследующий от `BaseModel`.

Используйте аннотации типов Python для всех атрибутов:

```Python hl_lines="7-11"
{!../../../docs_src/body/tutorial001.py!}
```

=== "Python 3.10+"

    ```Python hl_lines="18-20"
    {!> ../../../docs_src/body_multiple_params/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="18-20"
    {!> ../../../docs_src/body_multiple_params/tutorial001_an_py39.py!}
    ```
