    def __init__(self):
      question_types = (Add, Multiply)
      # generate 10 random questions with numbers from 1 to 10
      for _ in range(10):
        num1 = random.choice(1, 10)
        num2 = random.choice(1, 10)
        question = random.choice(question_types)(num1, num2)
      # add these questions into self.questions
        self.questions.append(question)

Relooking at Kenneth's code, the self. should not be necessary. There is something else not right with the code.

There is a syntax error in num1 = random.choice(1, 10). random.choice takes only one argument. I think you meant to use num1 = random.randint(1, 10). Is the code above your "final" version?

If you want to investigate further, please post your updated code and your questions.py file,

Need to add self. in front of question_type:

class Quiz:
    questions = []
    answers = []

    def __init__(self):
        self.question_types = (Add, Multiply) #<-- added 'self'

Thanks it works but how comes kenneth's code runs fine without self in front of question_types
