python set remove if exists

set.discard('element')

Here is what the above code is Doing:
1. We create a set called my_set.
2. We add the element ‘element’ to the set.
3. We remove the element ‘element’ from the set.
4. We try to remove the element ‘element’ from the set again.

The first two lines of code work as expected. The third line of code removes the element ‘element’ from the set.

The fourth line of code throws an error because the element ‘element’ is not in the set.

The discard() method is similar to the remove() method. The difference is that the remove() method throws an error if the element is not in the set, while the discard() method does not.
