We used tkinter for making the gui. We faced a problem when we wanted to go to the next question of the quiz. We intially tried to use a for loop to iterate through the questions. But then we failed to find a way to delay the next iteration of the loop so that the user can answer the previous question.

In the end we figured out a way to go through all the questions without using a loop. We declared a global variable that will store the question number. We made the tkinter function displaying the question call itself everytime we click the next button until we reach the last question.
