When should I use mutable or immutable sets?

Can you explain when to use mutable or immutable sets in Python?

Sure! Mutable sets can be changed after creation, while immutable sets cannot. Use mutable sets when you need to modify the set, and immutable sets for fixed collections.

What are some examples of when I might need a mutable set?

You might use a mutable set when you need to add or remove elements dynamically, like tracking unique user IDs in a session.

And when would an immutable set be more appropriate?

An immutable set is great for ensuring that the data remains constant, such as using it as a key in a dictionary or for fixed configurations.

Are there performance differences between the two?

Yes, immutable sets can be slightly faster for lookups since they are hashable, while mutable sets may have overhead due to their dynamic nature.
