I want the code I currently have to go through a list of questions infinitely or until someone gets an answer wrong. I am currently using

```
random.shuffle(questions)

for question in questions:
    question.ask()

```

to ask every question in a list once.

How do I make it continuously ask until the user inputs a wrong answer? Here is my current code:

```
class Question(object):
    def __init__(self, question, answer):
        self.question = question
        self.answer = answer

    def ask(self):

        response = input(self.question)
        if response == self.answer:
            print "CORRECT"
        else:
            print "wrong"

questions = [
    Question("0", 0),
    Question("π/6", 30), 
    Question("π/3", 60),
    Question("π/4", 45),
    Question("π/2", 90),
    Question("2π/3", 120),
    Question("3π/4", 135),
    Question("5π/6", 150),
    Question("π", 180),
    Question("7π/6", 210),
    Question("4π/3", 240),
    Question("5π/4", 225),
    Question("3π/2", 270),
    Question("5π/3", 300),
    Question("7π/4", 315),
    Question("11π/6", 330),
    Question("2π",360),
]

```

Also, if you could tell me how to add one score for every question correct that would be much appreciated. I tried to do this but I already have a piece of the program that deducts 1 from a global score variable every 5 seconds. I would like to continue editing that same variable but it gives errors.
