Can't figure out how to use .format in a class method.

On this code challenge, it asks me to create a method inside of the class Store. I think I understand that from the video but can't seem to figure out how to use the .format in it. I feel lost for the first time so I would appreciate help!

Thanks in advance!

method.py 
class Store:
  open = 9
  close = 7

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

You are very close. You need some "self help":

class Store:
    open = 9
    close = 7

    def hours(self):
        # refer to attributes using the 'self.' prefix
        openclose = "We're open from {} to {}.".format(self.open, self.close)
        # local variables do not use 'self.' prefix
        return openclose

Ohh! For some reason that thought didn't even enter my mind. Thanks!
