Convert list to set in Python

In this tutorial, I will be sharing how to convert list to set in python. As we know set does not allow duplicates i.e contains only unique elements without any order. Our main goal should be to remove all the duplicates present in the given list.


Note: We will use python set() method to convert list to set.

Example of Converting list to set in Python
