In python frozenset is similar to set but unlike set, elements cannot be added or removed from a frozenset since they are frozen. Frozenset can be used as Dictionary keys(since keys in a Dictionary are immutable) and also as elements in another set.

example :
fruits = {‘apple’, ‘banana’, ‘cherry’}
x = frozenset(fruits) #
x[1] = “strawberry” #Attempting to modify a frozenset will result in a TypeError# If you need to modify the set, we need to use a regular set instead
fruits.add(“strawberry”)
print(fruits)

Frozen set is just an immutable version of python set.
