Hey Saro there are just two small mistakes in your code:

  1. The question asks you to make a class variable called sound that holds any string value other than 'Roar'
  2. Secondly when you create a class method, you do not need to prefix the method name with the class name

Here what it look like: 

from animal import Animal

class Sheep(Animal):
    sound = 'Maaaaaaa'

    def noise(self):
        return self.sound.upper()
