Question

The local driver's license office has asked you to design a program that grades the written portion of the driver's license exam. The exam has 20 multiple choice questions. Here are the correct answers:

B

D

A

A

C

A

B

A

C

D

B

C

D

A

D

C

C

B

D

A

Your program should store these correct answers in an list. (Store each question's correct answer in an element of a String list). The program should ask the user to enter the student's answers for each questions, which should be stored in another list. After the student's answers have been entered, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam). The program should also display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly answered questions.

Notes:

1. Python program

2. Your program needs three lists: the first list holds the correct answers, the second list holds the student's answers, and the third list holds the question numbers for those questions that are not answered correctly.

3. Input validation is required for student's answers: when the input is not A, B, C, or D, your program needs to display an error message and get another input. The input validation is done using a while loop.

4. After getting the student's answers, the program will compare the two lists. If a question is answered wrong, the question number of that question will be put into the third list.

Answer 1

Program:

correctAnswers=["B","D","A","A","C","A","B","A","C","D","B","C","D","A","D","C","C","B","D","A"]
studentAnswers = []
questionNums=[]
i = 1
print("Enter your answers : ")
while (i <= 20):
    answer = input() # Taking answers input from user
    if (answer == "A" or answer == "B" or answer == "C" or answer == "D"):
        studentAnswers.append(answer)
        i = i + 1
    else:
        print("Please enter a valid answer")
    
for x in range(20):
    if correctAnswers[x] != studentAnswers[x]: # Comparing the answers
        questionNums.append(x+1)
        
if len(questionNums) > 5:
    print("Oops!! You have failed the exam")
else:
    print("Yayy!! You have passed the exam")
# Printing output
print("Total corrected answers :", 20-len(questionNums))
print("Total incorrected answers :", len(questionNums))
print("Incorrected question numbers list :", questionNums)

Output:
