frozenset Data Type in Python

It is exactly same as set except that it is immutable. 

Hence we cannot use add or remove functions.

>>> s=(10,20,30,40)

>>> fs-frozenset(s)

>>> type(fs)

<class 'frozenset'> 5) >>> fs

frozenset((40, 10, 20, 30))

>>> for i in fs:print(i)

40 10 20 30

>>> fs.add(70)

AttributeError: 'frozenset' object has no attribute 'add' 

>>> fs.remove(10)

AttributeError: 'frozenset' object has no attribute 'remove'
