In this video, we’ll dive into Python Sets, a powerful data structure that stores unordered, unique elements.
Unlike lists or tuples, sets do not allow duplicates and are optimized for operations like membership tests, unions, and intersections.

What You'll Learn:

•⁠ ⁠What is a Set? – Concept of sets and their key properties (unordered, unique, mutable)
•⁠ ⁠Creating Sets – Different ways to define a set in Python
•⁠ ⁠Accessing Elements – Why sets don’t support indexing or slicing
•⁠ ⁠Set Operations – Union, intersection, and difference with practical examples
•⁠ ⁠Use Cases – Real-world examples where sets are most efficient (e.g., removing duplicates, fast membership testing)

By the end of this tutorial, you’ll understand how to use sets in Python effectively and when to prefer them over lists or tuples.
