All the same process that applied for path parameters also applies for query parameters:

* Editor support (obviously)
* Data <abbr title="converting the string that comes from an HTTP request into Python data">"parsing"</abbr>
* Data validation
* Automatic documentation

Функция `Field` работает так же, как `Query`, `Path` и `Body`, у неё такие же параметры и т.д.

/// note | "Технические детали"

На самом деле, `Query`, `Path` и другие функции, которые вы увидите в дальнейшем, создают объекты подклассов общего класса `Param`, который сам по себе является подклассом `FieldInfo` из Pydantic.
