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

Method named 'hours' is supposed to use .format() to return "We're open from {} to {}"

The 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

I don't understand what you want.. i rewatched all the previous videos and there was NOTHING mentioned about .format(). I have tried answering the question every way possible and got nothing

The format() function is heavily used in Kenneth videos. You have to put those placeholders ({}) inside of the string, and then in the arguments of the format() function put what you want to appear inside of those placeholders.

class Store:
    open = 9
    close = 21

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

I hope that helps a little bit

I am still trying to understand why there is self.open, self,close.

Hi I am just wondering why is it self. open and self.close instead of just open and close?

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

return needs to have "()" so you can pass through the prompt
