questions related to frozenset objects in Python

frozenset is a built-in type for Python programming language. The elements of a set must be hashable. To represent sets of sets, the inner sets must be frozenset objects.

A set is a collection in which no element is repeated. It is often implemented by hashing the objects as they are added to the set, and comparing against those hashes for operations on the set.
