І знову ж таки, ви отримуєте всю підтримку редактора:

## Pydantic моделі

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> це бібліотека Python для валідації даних.

Ви оголошуєте «форму» даних як класи з атрибутами.

І кожен атрибут має тип.

{!../../docs_src/python_types/tutorial010.py!}
```

然后，你将再次获得所有的编辑器支持：

## Pydantic 模型

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> 是一个用来用来执行数据校验的 Python 库。

你可以将数据的"结构"声明为具有属性的类。

每个属性都拥有类型。

接着你用一些值来创建这个类的实例，这些值会被校验，并被转换为适当的类型（在需要的情况下），返回一个包含所有数据的对象。

然后，你将获得这个对象的所有编辑器支持。
