Python Object-Oriented Python (retired) Objects Create a Class with a Method

Method not working in challenge but seems to work fine in console.

Here is the challenge question:

Now, add a method named hours that returns "We're open from {} to {}.". Replace the first placeholder with the open time and the second with the close time. Remember you need to pass keywords to .format() if your placeholders have names.

Here is my code:

class Store:
    open = 9
    close = 10

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

I try it in a Python console and it gives me the expected output:

We're open from 9 to 10

But I can't get it to work in the challenge and it gives me no hints on how to fix it. Just a "Bummer! Try again!"

Your hours method doesn't have self as the first (and, really, only) argument and your open and close variables, inside, should be self.open and self.close. Other than that, looks good.

Thank you for that, it does make sense now.

class Store:
  open = 9
  close = 10

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

That worked to complete the challenge, but I am sure I could just remove the variable and just return it like this?

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