Python Data Types: Sets - Exercises, Practice, Solution

Python Sets [ 30 exercises with solution]

A set object is an unordered collection of distinct hashable objects. It is commonly used in membership testing, removing duplicates from a sequence, and computing mathematical operations such as intersection, union, difference, and symmetric difference.
