Python is a powerful programming language that provides various built-in data structures to store and manipulate data. The set data structure is one of them. A set is an unordered collection of unique elements. In this article, we will discuss how to create a set from a list in Python.

Step-by-Step Guide

Here are the steps to create a set from a list in Python:

Step 1: Create a List

The first step is to create a list of elements. For example, let's create a list of integers:

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

Step 2: Convert List to Set

The next step is to convert the list to a set using the built-in set() function in Python. Here is how you can do it:

my_set = set(my_list)

Step 3: Output the Set

Finally, you can output the set to verify that it only contains unique elements:


The output will be:

{1, 2, 3, 4, 5}


In this article, we have discussed how to create a set from a list in Python. The process is straightforward and can be accomplished in just a few steps using the built-in set() function. Keep in mind that sets are unordered collections of unique elements, which can be useful in many programming scenarios.
