Keep getting this in PyDev "TypeError: quiz() takes exactly 1 argument (0 given)"

[Chuck]

Thanks for the help guys!  I finally got it working.  Shouldn't I technically call quiz() through the constructor, though?  Otherwise, the constructor is pointless.  I just put in pass for now.  (Also, I always thought that if __name__ == '__main__': went IN the class.  Why wouldn't it be apart of the class?  )

Thanks again!
