python 3.x comparing variables

[mcmxl22]

Why doesn't this work in Python 3.x?

quarters = input('How many quarters do you have? ')
if quarters <= 8:
    print ('You need more money.')

I get this error from the original program here.

Error:
Traceback (most recent call last):
  File "house.py", line 118, in <module>
    front_porch()
  File "house.py", line 21, in front_porch
    living_room()
  File "house.py", line 106, in living_room
    basement()
  File "house.py", line 67, in basement
    if quarters <= 8:
TypeError: '<=' not supported between instances of 'str' and 'int'

change:

quarters = input('How many quarters do you have? ')

to

quarters = int(input('How many quarters do you have? '))
