Vous aurez des propositions de complétion que vous n'auriez jamais imaginées. Par exemple la clé `prix` dans le corps d'un document JSON (qui est peut-être imbriqué) venant d'une requête.

Plus jamais vous ne vous tromperez en tapant le nom d'une clé, vous ne ferez des aller-retour entre votre code et la documentation ou vous ne scrollerez de haut en bas afin d'enfin savoir si vous devez taper `username` ou `user_name`.

To handle that, we first convert the `username` and `password` to `bytes` encoding them with UTF-8.

Then we can use `secrets.compare_digest()` to ensure that `credentials.username` is `"stanleyjobson"`, and that `credentials.password` is `"swordfish"`.
