I am making a quiz program using the Python GUI interface. When the start button is selected, a random question is generated. User will next select true of false and then select the submit button.
How do I do this ?: I need to check the user attempt against the answer and display either ‘Question X is correct’ or ‘Question X is incorrect! in the Scrolled Text below’.

Hi you can use a dictionary for the question and answers After which when you randomly select the question store a reference to the answer as well.
self._question, self._answer = random.choice(list(Questions.items()))
