## Типи множин

Але потім ми подумали, що теги не повинні повторюватися, вони, ймовірно, повинні бути унікальними рядками.

І Python має спеціальний тип даних для множин унікальних елементів — це `set`.

Тому ми можемо оголосити `tags` як множину рядків:

                and send the client an error.

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