why is this method wrong?

This doesn't seem to pass the objective check, but I've no idea why?

method.py 
class Store():
  open = 9
  close = 5

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

Hey Y B !

It looks like you might have an issue with variable scope :)

So, in your hours method, you need to use self to access open and close like so:

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

This way, you are referencing the variables open and close that are members of the Store class and not variables that the compiler expects to be defined locally within the hours method.

Hi YB

The reason your not getting the desired result is because in your hours method you are trying to access the open and close properties without referencing the current instance.

do it this way

class Store():
    open = 9
    close = 5

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