It can have mutable objects. For example, a key k can have a list v as
value. You can modify v, but you can't assign to the key k another
value w. It's the same with the tuples, as you said. An index i can
contain a list l. Since it's a tuple, you can't set another object at
the index i, but you can modify the list l.
