Question

I am trying to code a basic quiz application. For some reason when I move forwards and back again the mini-quiz won’t reset like I think it should. For example if I’m midway through a quiz and if I decide to hit the arrow forwards then back again my progress should be reset. I have two scripts I’m showing you one is my main.py and the other is referred to as quizzes.py. There is also an excerpt of the csv file I’m using for the quiz.
