Python is a versatile programming language loved for its ease of use and readability. It has been used to create various applications, from web applications to enterprise software.
Python frozenset( ) is a built-in function that uses elements from the specified iterable to return an immutable frozenset object.
Here we will learn the uses of Python frozenset( ) with examples. Also, this blog will discuss how Python frozenset( ) is different from the Python set.

Python frozenset(): Introduction
The frozenset( ) is a Python inbuilt function. Frozenset is just like Python set object except for its immutable nature. Immutable means that frozenset doesn’t allow any element to be added or removed once it is created. Whereas in the set, we can modify the elements as per choice.
Python frozenset( ) takes iterable objects as input and makes them unchangeable, immutable version. This function freezes those iterable objects and makes them immutable objects. Unlike sets, it does not guarantee any order of elements to be preserved.
The Python frozenset( ) is used as the key in Dictionaries because of its immutable nature.
Python frozenset( ): Syntax
Here is Python frozenset syntax:
frozenset(iterable_object) There is only one single input parameter:
Iterable_object: Initializes the frozenset with the elements; Iterables include set, tuple, list, dictionary, etc.
In the output, frozenset( ) function returns an immutable frozenset.
Note: An empty frozen set in input returns an empty frozen set in output, as no parameters are passed.
Let’s study a few examples to learn better.
Example No. 01
Here is a simple example to understand Python frozenset( ).
vowels = ('a', 'e', 'i', 'o', 'u')
f_letters = frozenset(vowels)
print("Frozenset Object: ", f_letters)
Output
Example No. 02
This example explains how to use Python frozenset( ) for keys in Dictionary.
Dictionary= {"name": "Robert", "sex": "Male", "age": 21 }
Key = frozenset(Dictionary)
print('The Frozen Set Object:', Key)
Output
FAQs
What are the advantages of using a frozenset overusing lists or tuples?
There are a few advantages to using a frozenset over lists or tuples. First, a frozenset is more efficient because it can store multiple values in a single location. It is more reliable as it maintains its data integrity. A frozenset is easier to use because it allows you to select a specific value without searching through the entire set.
Can you perform any other useful operations on a frozenset besides creating, indexing, and slicing it like lists and tuples?
You can perform other useful operations on a frozenset besides creating, indexing, and slicing it like lists and tuples. For example, you can find union, intersect, and symmetric difference on a frozenset.
What are some useful operations that can be performed on a frozenset?
A frozenset is a powerful tool that can be used for a variety of operations, such as data restoration, file synchronization, and even data migration. It can also be used to clone drives and servers.
Conclusion
Python frozenset is immutable type that provides a concise and easy-to-read way to manage collections of data. This blog discussed the advantages and uses of Python’s frozenset( ) along with key differences of frozenset and set. I hope the examples helped you in learning Python frozenset efficiently.
