How do I remove elements from a set in Python?

How do I remove elements from a set in Python?

You can use the remove() method to remove an element from a set. If the element is not found, it raises a KeyError.

What if I want to remove multiple elements?

You can use the difference_update() method or a loop to remove multiple elements from a set.

Can you show me an example?

Sure! Here's an example:

my_set = {1, 2, 3, 4}
my_set.difference_update({2, 3})
print(my_set)  # Output: {1, 4}

Is there a way to remove an element without raising an error if it doesn't exist?

Yes, you can use the discard() method. It removes the element if it exists, and does nothing if it doesn't.
