Class method code challenge: returning string not working

My code is shown below. I can create the class fine but the second step says to define a class method named hours that returns the string that you can see in the code. I'm pretty sure I did the format function correctly.

I don't think your code made it in the post, could you provide it?

I tried with and without using self as an argument.

class Store:
  open = 10
  close = 12

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

Your solution is very close! You just need to pass 'self' into your hours def. *update after your updated post: Looks like you were not calling self on the open and close hours.

class Store:
    open = 9 
    close = 5
    def hours(self): 
      return "We're open from {} to {}. ".format(self.open,self.close)

Ah, thanks, I could not for the life of me figure it out. But I forgot that you have to call self on the variables also.

But shouldn't it work anyways if I don't call self on anything?

The open and close variables are not global. so you you have to pass them into you hours method. If you had multiple stores with multiple open hours you'd want to pass in the self value for each store to make sure you have the right values for each store.
