What is the difference between remove() and discard() in Python sets?

Can you explain the difference between remove() and discard() in Python sets?

Sure! In Python, both remove() and discard() are used to delete elements from a set, but they behave differently when the element is not found.

What happens if I use remove() on an element that doesn't exist?

If you use remove() on an element that doesn't exist in the set, it will raise a KeyError.

And what about discard()?

If you use discard() on an element that doesn't exist, it will simply do nothing and won't raise an error.

So, when should I use one over the other?

Use remove() when you want to ensure the element is present and want to handle the error if it's not. Use discard() when you want to avoid errors and don't mind if the element is absent.
