Er zijn enkele datastructuren die andere waarden kunnen bevatten, zoals `dict`, `list`, `set` en `tuple` en waar ook de interne waarden hun eigen type kunnen hebben.

Deze types die interne types hebben worden “**generieke**” types genoemd. Het is mogelijk om ze te declareren, zelfs met hun interne types.
