## Declare escopos em *operações de rota* e dependências

Agora nós declaramos que a *operação de rota* para `/users/me/items/` exige o escopo `items`.

Para isso, nós importamos e utilizamos `Security` de `fastapi`.

        and `tf.data.Dataset.with_options()` respectively.
    *   New `tf.data.Dataset.reduce()` API allows users to reduce a finite
        dataset to a single element using a user-provided reduce function.
    *   New `tf.data.Dataset.window()` API allows users to create finite windows
        of input dataset; when combined with the `tf.data.Dataset.reduce()` API,
        this allows users to implement customized batching.
