Function Details: frozenset

Description

Returns an immutable set object initialized from iterable.

Extended Description

The frozenset() function returns an immutable set object. Like sets, frozensets are unordered collections of unique elements, but unlike sets, frozensets are immutable and hashable. This makes them suitable for use as dictionary keys or as elements of other sets. If no argument is passed, it returns an empty frozenset.

Exceptions

TypeError: If the iterable contains unhashable objects
