Ele também declara novamente `id: int`. Ao fazer isso, estamos fazendo um **contrato** com os clientes da API, para que eles possam sempre esperar que o `id` estará lá e será um `int` (nunca será `None`).

You would do the same to declare `tuple`s and `set`s:

{* ../../docs_src/python_types/tutorial007_py39.py hl[1] *}

This means:

* The variable `items_t` is a `tuple` with 3 items, an `int`, another `int`, and a `str`.
* The variable `items_s` is a `set`, and each of its items is of type `bytes`.

#### Dict { #dict }

To define a `dict`, you pass 2 type parameters, separated by commas.
