What are the advantages of using sets in Python?

Sets in Python are unordered collections of unique elements. They offer advantages like fast membership testing, eliminating duplicates, and efficient operations like unions and intersections.

Can you explain how sets handle duplicates?

Sure! Sets automatically remove duplicate entries. If you try to add a duplicate item, it simply won't be included in the set.

What operations can I perform with sets?

You can perform various operations like union, intersection, difference, and symmetric difference, which are very efficient with sets.

Are there any performance benefits to using sets?

Yes, sets provide average time complexity of O(1) for membership tests, making them faster than lists for checking if an item exists.

Can you give an example of using sets in a real-world scenario?

Absolutely! For instance, you can use sets to find unique user IDs from a list of registrations, ensuring no duplicates.
