In this video, you’ll learn how Python sets automatically remove duplicate values in a simple and practical way.
A set is a data structure that only stores unique elements, so duplicate values are automatically ignored.
💡 What you will learn:
How to create a set in Python
How Python removes duplicate values automatically
How to find the length of a set using len()
Understanding the uniqueness property of sets
⭐ Example covered:
create a set with duplicates
numbers = {1, 2, 2, 3, 3, 3, 4}
print the set
print(numbers) # {1, 2, 3, 4}
print the length of the set
print(len(numbers))
⭐ Key Concept:
In Python, sets only store unique values — duplicates are automatically removed.
