您好我很抱歉这样的问题，但我正在学习python，我正在使用名为[学习python艰难的方式]的书。在练习43_Classes.py我无法弄清楚为什么我的输出提供了无效的语法我希望有人在这里指出这个脚本出了什么问题谢谢你。

我想在你的Map课程中想要一本字典：
class Map(object):
scenes = {
"central_corridor": CentralCorridor(),
"laser_weapon_armory": LaserWeaponArmory(),
"the_bridge": TheBridge(),
"escape_pod": EscapePod(),
"death": Death()
}
