在Python中访问类的变量时遇到的问题

Question

这里是新学员。我尝试了here指示的方法，但没有成功。你能帮我解决下面的代码吗？我似乎无法让Escape Pod类访问Central Corridor类中的gothonlife变量。继续收到此错误消息“类型对象'CentralCorridor'没有属性'gothonlife'？谢谢！

class Scene(object):

    def enter(self):
        pass


class Engine(object):

    def __init__(self, scene_map):
        print "On the floor you find a map with the following options. \n 1) Central Corridor \n 2) Laser Weapon Armory \n 3) The Bridge \n 4) Escape Pod. \n Where do you want to go?"
    door = raw_input("> ")

    count = 0
    while (count < 1):

        if door == "Central Corridor":
            count = count + 1
            object1 = CentralCorridor()
            object1.enter()

        elif door == "Laser Weapon Armory":
            count = count + 1

        elif door == "The Bridge":
            count = count + 1

        elif door == "Escape Pod":
            count = count + 1
            object5 = EscapePod()
            object5.enter()

        else:
            print "Erm... where exactly do you want to go again?"
            door = raw_input("> ")

class CentralCorridor(Scene):

        print "There stands a Gothon. What do you want to do with him? \n 1) Offensive attack \n 2) Defensive attack \n 3) Suicide"

        gothonlife = 10
        herolife = 10

        def __init__(self):
            self.gothonlife = gothonlife

    while (gothonlife > 0 and herolife > 0):
        action = raw_input("What now? Offensive attack, defensive attack or suicide?")

        elif action == "Suicide":
            herolife = herolife -11
            print "your life stands at %s, the enemy life be at %s" % (herolife, gothonlife)

        else:

        object2.enter()
    elif herolife >0:

            object4 = CentralCorridor()
            object4.enter()
        elif CentralCorridor.gothonlife < 0:
            print "You escape from Gothon! Congrats!"



class Map(object):

    def __init__(self, start_scene):
