When should I use sets in Python?

You should use sets in Python when you need to store unique items, perform set operations, or check for membership efficiently.

Can you give me an example of when to use a set?

Sure! If you want to find unique elements in a list, using a set can help eliminate duplicates easily.

What are the performance benefits of using sets?

Sets offer average O(1) time complexity for membership tests, making them faster than lists for checking if an item exists.

Are there any downsides to using sets?

Yes, sets are unordered and do not support indexing, so if you need to maintain order or access elements by index, consider using lists.
