  def hours(self, open, close):

Hi there Maciej, I have taken a look at you code and have found where you went wrong. When defining the hours method, the only argument that needs to be passed in is self. Then if you wanted to use the attribute e.g. open, you would write self.open instead. Here is what your code should look like:

class Store(object):
  open = 9
  close = 22

  def hours(self):
    return("We're open from {} to {}.".format(self.open, self.close))
