How do sets and lists compare in Python performance?

What are the performance differences between sets and lists in Python?

Sets in Python are generally faster for membership tests compared to lists because they use a hash table for storage.

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

Use a set when you need to ensure all elements are unique or when you need fast membership checks.

What about the memory usage between sets and lists?

Sets typically use more memory than lists due to the overhead of storing hash values.

Are there any scenarios where lists are better than sets?

Yes, lists are better when you need to maintain order or allow duplicate elements.
