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`).

because the path parameter `item_id` had a value of `"foo"`, which is not an `int`.

The same error would appear if you provided a `float` instead of an `int`, as in: <a href="http://127.0.0.1:8000/items/4.2" class="external-link" target="_blank">http://127.0.0.1:8000/items/4.2</a>

porque el parámetro de path `item_id` tenía un valor de `"foo"`, que no es un `int`.

El mismo error aparecería si proporcionaras un `float` en lugar de un `int`, como en: <a href="http://127.0.0.1:8000/items/4.2" class="external-link" target="_blank">http://127.0.0.1:8000/items/4.2</a>
