Please help Why does it still get lower case when I have infused upper case all over?
Challenge Task 3 of 3
Animal.noise() returns self.sound.lower(). Make Sheep.noise() return the uppercased version of the instance's sound.
Why does it return expected "SNEEZE" but got "sneeze"? Surely I have put lots of upper() all over. Is there a bug in this task?
from animal import Animal class Sheep(Animal): sound = "SNEEZE".upper() def __init__(self, sound): self.sound = 'SNEEZE'.upper return self.sound.upper()

The key here is inheritance. The challenge checker is running
Sheep.noise() to get the sound. If there is not a method name
Sheep, it will try to run the inherited method from the parent class. This is
Animal.noise() which returns self.sound.lower().
To solve the challenge, create a
noise which will override the inherited
Animal.noise(). It is in the
Sheep.noise() that you use the
upper() method to get the result you are looking for.
Post back if you have more questions. Good Luck!!!
from animal import Animal class Sheep(Animal): sound = 'roar' def noise(self): return self.sound.upper()
