Chú ý rằng, biến `item` là một trong các phần tử trong danh sách `items`.

Và do vậy, trình soạn thảo biết nó là một `str`, và cung cấp sự hỗ trợ cho nó.

#### Tuple and Set

Bạn sẽ làm điều tương tự để khai báo các `tuple` và  các `set`:

                By default, if the query parameter is not provided, `APIKeyQuery` will
                automatically cancel the request and send the client an error.

                If `auto_error` is set to `False`, when the query parameter is not
                available, instead of erroring out, the dependency result will be
                `None`.

                This is useful when you want to have optional authentication.
