The frozenset is a built-in function in Python. The simple and easy method comes to our mind to loop over lists of dictionaries and compares the value for a duplicate to remove the duplicate value. Possible solution: add an ordered subtype of frozenset which would keep an array of items in the original order. It is same as set, but its elements are unchangeable. In such scenario, we apply the frozenset () function as shown below. Python frozenset returns immutable version of set.Unlike set, once frozenset is created, it can not be modified.It is suitable for keys in the dictionary. The constructor set is used to create the sets. Since python set is iterable, we can use for loop to iterate over individual items of the python set. Example 1: Working of Python frozenset (). When you use a dictionary as an iterable for a frozen set, it only takes keys of the dictionary to create the set. Example of creating a frozen set in python. Python provides another built-in type called a frozenset. In this Part 4 of Python Data Structure series, we will be discussing what is a set, how it differs from other data structure in python, how to create set objects, delete set objects and methods of set objects.
