I'm delighted to welcome you to our Python Sets lesson! Remember, sets are like lists or tuples, except they can only hold unique elements. They're especially useful when you need to guarantee that elements in a collection appear only once.

In this lesson, you'll consolidate your knowledge of creating and operating on sets. You will learn about the special frozen sets and discover how sets enhance performance. Ready, Set, Go!

Python provides methods to manipulate sets, such as add(), in, remove(), and discard().
