class methods

what's the difference between the below two class methods. the second one seem to work differently though / or doesn't work as desired as its not accessible via the instance...

class Store:
    open = 9
    close = 3

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


class Store:
    open = 9
    close = 3

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

There are two errors in the second example.

First, you left off the return statement, so while the string is formatted, the result does not go back to the caller.

Second, you prefaced your variables with Store, but you need self to reference instance variables.
