Dictionaries in Python require their keys to be immutable. As a result, a set cannot be used as keys as it is mutable. Yet, if you want to use a set, consider declaring it as a frozenset. It is an immutable set, meaning its elements cannot be changed after it is created. Therefore, they can be safely used as a dictionary’s key.
