In Quiz class, we have a answers = [] list which stores correct answers. Hence, I would assume that answers list looks like this [1, 10, 4, ....] a list of numbers. So When we want to check if user's answer is in the list, we just do for loop, and I don't get what the answer[0] does. answer is an integer, how come answer[0] works?

This might make more sense after you get to the point where the project is complete.

231,275 PointsSorry for the delay in responding, but yes, at this point of the project there are just 2 parts, the right/wrong boolean and the time to answer. I was probably thinking of a later expansion that had 3 parts.
