Set vs Tuple in Python

Python is an object-oriented programming language that provides different data types to store data. Two such data types are sets and tuples. Although both data types are used to store a collection of elements, they differ in their functionality and properties. In this blog post, we will discuss sets and tuples in detail, their differences, and how to use them in Python.

Sets in Python:

A set is an unordered collection of unique elements. In Python, sets are represented using curly braces {}. The elements in a set are enclosed in the braces, separated by commas. Here’s an example of how to create a set in Python:

my_set = {1, 2, 3, 4, 5}

In the above example, we have created a set named my_set with five elements.

Tuples in Python:

A tuple is an ordered collection of elements that are immutable, meaning that once a tuple is created, its elements cannot be modified. In Python, tuples are represented using parentheses (). The elements in a tuple are enclosed in the parentheses, separated by commas. Here’s an example of how to create a tuple in Python:

my_tuple = (1, 2, 3, 4, 5)

In the above example, we have created a tuple named my_tuple with five elements.

Differences between Sets and Tuples:

  1. Mutability: Sets are mutable, meaning that their elements can be added, removed, or modified after the set is created. On the other hand, tuples are immutable, meaning that their elements cannot be modified after the tuple is created.
  2. Order: Sets are unordered, meaning that their elements do not have a specific order. Tuples, on the other hand, are ordered, meaning that their elements have a specific order.
  3. Duplicate Elements: Sets cannot have duplicate elements, meaning that each element in a set must be unique. Tuples can have duplicate elements.
  4. Indexing: Sets do not support indexing, meaning that we cannot access elements in a set using an index. Tuples support indexing, meaning that we can access elements in a tuple using an index.
  5. Brackets: Sets are represented using curly braces {}, while tuples are represented using parentheses ().


Let’s consider a scenario where we have a list of numbers and we want to create a set and a tuple from it. Here’s how we can do that:

numbers_list = [1, 2, 3, 4, 5]

# Creating a set from the list
numbers_set = set(numbers_list)

# Creating a tuple from the list
numbers_tuple = tuple(numbers_list)

In the above example, we have created a list named numbers_list with five elements. We have then created a set named numbers_set and a tuple named numbers_tuple from the list. We have used the set() function to create a set from the list, and the tuple() function to create a tuple from the list.


{1, 2, 3, 4, 5}
(1, 2, 3, 4, 5)


In conclusion, both sets and tuples are important data types in Python, each with its own unique properties and functionalities. While sets are mutable, unordered, and do not support indexing, tuples are immutable, ordered, and support indexing. Choosing between sets and tuples depends on the specific use case and the requirements of the program. It is important to understand the differences between the two data types and use them appropriately to achieve the desired results in your Python programs.
