For which reason is the method able to access the variable sound?

I probably did not get the concept behind passing values as parameters.

Why is this code wrong:

sheep.py
from animal import Animal

class Sheep(Animal):
  sound ='bark'

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

[MOD: added ```python formatting -cf]

It looks like you're very close.

I'm going to assume that your indentation is not an issue, even though it's impossible to tell with the unformatted code shown.

But otherwise, it looks like you just have a spurious second parameter named sound in your definition of noise. Remove that and you should pass.

For future questions, be sure to format your code using the instructions from the Markdown Cheatsheet found below the "Add an Answer" area. :arrow_heading_down:
