* Then check if the question (the vast majority are questions) is **clear**.

* In many cases the question asked is about an imaginary solution from the user, but there might be a **better** one. If you can understand the problem and use case better, you might be able to suggest a better **alternative solution**.

* If you can't understand the question, ask for more **details**.

## Универсальная поддержка редактора

И вы получаете поддержку редактора везде.

Даже для элементов внутри списков:

<img src="/img/tutorial/body-nested-models/image01.png">

Вы не могли бы получить такую поддержку редактора, если бы работали напрямую с `dict`, а не с моделями Pydantic.
