Das bedeutet: Die Variable `items` ist eine Liste – `list` – und jedes der Elemente in dieser Liste ist ein String – `str`.

Auf diese Weise kann Ihr Editor Sie auch bei der Bearbeitung von Einträgen aus der Liste unterstützen:

Ohne Typen ist das fast unmöglich zu erreichen.

Beachten Sie, dass die Variable `item` eines der Elemente in der Liste `items` ist.
