Summary

• Implements answer checking functionality in QuizBrain class by comparing user input with correct answers
• Adds score tracking to measure user performance throughout the quiz
• Converts answers to lowercase for case-insensitive comparison
• Displays current score after each question as ratio of correct answers to total attempts
• Shows final score and completion message when quiz ends

Notes\ Code

Our code is nearly finished, we just need the ability to check our answers, and to do this our QuizBrain class needs a new method called check_answer(), as well as a new attribute to hold the score.

We add score to our init real quick.

    def __init__(self, q_list):
        self.question_number = 0
        self.question_list = q_list
        self.score = 0

To check our user’s answer we need to make the input taking it, placed inside a variable. Easy enough:

    def next_question(self):
        current_question = self.question_list[self.question_number]
        self.question_number += 1
        user_answer = input(f"Q. {self.question_number}: {current_question.text} (True/False): ")

Now we need to create the check_answer function but we also need to call it inside of next_question and pass it the user_answer as well as the correct answer stored in our current_question variable. We can do this simply enough, and much like we got the text for the question in our input by calling the current_question variable and saying current_question.text, we can just say current_question.answer to pass that information along. Now next_question looks like this:

    def next_question(self):
        current_question = self.question_list[self.question_number]
        self.question_number += 1
        user_answer = input(f"Q. {self.question_number}: {current_question.text} (True/False): ")
        self.check_answer(user_answer, current_question.answer)

So lets write our check_answer method now:

    def check_answer(self, user_answer, correct_answer):
        if user_answer.lower() == correct_answer.lower():
            print("That is correct")
            self.score += 1
        else:
            print("That is incorrect")
        print(f"Your current score is {self.score}/{self.question_number}")
