Das bedeutet:

* Die Variable `items_t` ist ein `tuple` mit 3 Elementen, einem `int`, einem weiteren `int` und einem `str`.
* Die Variable `items_s` ist ein `set`, und jedes seiner Elemente ist vom Typ `bytes`.

#### Dict

Um ein `dict` zu definieren, übergeben Sie zwei Typ-Parameter, getrennt durch Kommas.
