Why both class attributes and instance attributes are in the classes?
I saw Kenneth had both 'questions = ', class attributes, and 'self.questions', instance attributes, in Quiz class. But I don't understand why. Also in questions.py, he used 'answer = None' and 'text = None' but in Add and Multiply class he used self.answer and self.text instead. Are class attributes in this scenario necessary? Thank you.
