Question

错误：第29行，在地图'empty_room'中：我曾尝试重写我的课程和其他小东西，但却无法提出任何解决方案。我的缩进在记事本上是正确的（或似乎是这样），他们只是没有很好地转移到SOF。任何故障排除表示赞赏:)谢谢！

P.S。我正在学习“学习Python艰难之路”这本书，我正在做一个类似于zork的游戏练习。希望这会有所帮助。

Answer 1

在使用类定义之前，它应该首先出现。

class EmptyRoom(Scene):
    def enter(self):
        print ""
        action = raw_input("> ")
        if action == "open door":
            return 'living_room'

class Map(object):
    scenes = {
        'empty_room': EmptyRoom(),
        ...
    }

LivingRoom，Office，Hallway，Kitchen，MasterBedroom，KidsBedroom，Attic相同。

Answer 2

scenes内Map的定义是在构建类时运行的，而不是在您稍后调用类来实例化它时。那时，EmptyRoom还不存在 - Python从代码的顶部开始工作，因此EmptyRoom仅在到达class EmptyRoom:下面的缩进块的末尾后才存在。因此，为了实现这一点，Map需要在所有其他类之后而不是之前。

错误：EmptyRoom（），NameError：未定义名称“EmptyRoom”
