## Recap

With `Query`, `Path` (and others you haven't seen yet) you can declare metadata and string validations in the same ways as with [Query Parameters and String Validations](query-params-str-validations.md){.internal-link target=_blank}.

And you can also declare numeric validations:

* `gt`: `g`reater `t`han

=== "Python 3.8+"

    ```Python hl_lines="11-14"
    {!> ../../../docs_src/body_fields/tutorial001.py!}
    ```

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.
