I am trying to make a math quiz on python, and I am trying not to use random. When I set user input to the answer of the problem and then try to run it, it says its wrong. Why? Here is apart of my code. When I answer '78' correctly, it says sorry that is not right.
def problem1():
raw_input('36 + 42 = ')
if input == '78':
print('Correct!')
else:
print('Sorry that is not right.')
