Trying something that is called Multiple Inheritance!

myTUP = ("APP", "BAN", "QUIRK")

class Mike:
    def __init__(self, myTUP):
        self.ITEMS = []
        self.__update_it(myTUP)

    def update(self, myTUP):
        for Item in myTUP:
            self.ITEMS.append(Item)

    __update_it = update # PRIVATE

class Mikes_APT(Mike):
    def update(self, keys, values):
        for Item in csv(keys, values):
            self.ITEMS.append(Item)
