Python属性创建了两个变量

Question

我有两个私有变量（属性），我给了它们getter和setter，现在它为每个创建了两个变量（我只想要一个，我希望它是私有的）：

_indoor_location_cards
indoor_location_cards
_outdoor_location_cards
outdoor_location_cards

我在调试器中发现了这一点。

这是我的代码：

the_game = None
class Game(object):
    """Template for the Zimp game."""
    _indoor_location_cards = []
    _outdoor_location_cards = []
    game_dev_cards = []
    the_user = None
    items = []
    the_time = None
    def __init__(self):
        pass

    #getter and setter for the private indoor card list
    def indoor_location_cards():
        doc = """The priavte list for indoor location cards
              of the game. Has a getter, setter, & deleter"""
        def fget(self):
            return self._indoor_location_cards
        def fset(self, value):
            self._indoor_location_cards = value
        def fdel(self):
            del self._indoor_location_cards[0:len(self._indoor_location_cards)]
        return locals()  # credit: David Niergarth
    indoor_location_cards = property(**indoor_location_cards())

    #getter and setter for the private outdoor card list
    def outdoor_location_cards():
        doc = """The priavte list for outdoor location cards
              of the game. Has a getter, setter, & deleter"""
        def fget(self):
            return self._outdoor_location_cards
        def fset(self, value):
            self._outdoor_location_cards = value
        def fdel(self):
            del self._outdoor_location_cards[0:len(self._outdoor_location_cards)]
        return locals()  # credit: David Niergarth
    outdoor_location_cards = property(**outdoor_location_cards())

def main():
    pass

if __name__ == '__main__':
    main()

the_game是一个模块范围变量，包含一个Game实例。

我只使用代码来设置像这样的the_games属性：

    model.zimp.the_game = model.zimp.Game()
        model.zimp.the_game.the_time = datetime.time(9, 0)
        # Add the indoor cards to the indoor cards list.
        model.zimp.the_game._indoor_location_cards.append(card1)
        model.zimp.the_game._indoor_location_cards.append(card2)
        model.zimp.the_game._indoor_location_cards.append(card3)
model.zimp.the_game._outdoor_location_cards.append(card9)
        model.zimp.the_game._outdoor_location_cards.append(card10)
        model.zimp.the_game._outdoor_location_cards.append(card11)
