I’m really sorry if I translated it wrong, English is not my native language. Thank you in advance for any help given.

Answer

This problem requires knowledge about Object oriented programming. You need to create a class named ‘IntSet’ which has methods ‘new_element’, ‘symmetric_difference’, ‘has_element’, ‘delete_element’ and ‘union’ with required functionalities. I recommended you follow some tutorials on python classes and objects.
