Question

You notice that users are entering upper case letters, complete responses, and other hard to deal with input. To help them out, you will extend your program so that if the user enters something other than 'a', 'b', or 'c' the program will immediately respond with

Invalid input! Enter a, b, or c next time.

Your program will go on to mark them incorrect.

This behavior will apply to the multiple choice questions only. Below is how your output should look for the first question:

ART AND LITERATURE: Who painted Starry Night?
a. Vincent van Gogh
b. Michelangelo
c. Leonardo da Vinci
Enter your choice:d
Invalid input! Enter a, b, or c next time.
The correct answer was a

Save this and submit it

----------------

result = 0

print('ART AND LITERATURE: Who painted Starry Night?')
print('a. Vincent van Gogh')
print('b. Michelangelo')
print('c. Leonardo da Vinci')

answer = input('Enter your choice:')
if answer == 'a':
print('Correct!')
result = result + 1
else:
print ('The correct answer was a')

Answer 1

CODE:

result = 0

print('ART AND LITERATURE: Who painted Starry Night?')

print('a. Vincent van Gogh')

print('b. Michelangelo')

print('c. Leonardo da Vinci')

while True: #Using an infinite loop for asking user until a valid input

answer = input('Enter your choice:')

#If it is a valid input in both upper and lower cases then we are verfying the input

if(answer.lower() == 'a' or answer.lower() == 'b' or answer.lower() == 'c'):

if answer.lower() == 'a': #If it is a valid input and correct answer

print('Correct!')

result = result + 1

else: #If it is a valid input and wrong answer, i.e in this case

print ('The correct answer was a')

break

#If it is not valid reponse, we are asking user to again enter input

else:

print('Invalid input! Enter a, b, or c next time.')
