Python 2.7 使用字典选择游戏中的场景，但它'；这不是正确的场景。为什么？

开始时，如果一个随机整数=1，它将播放一个随机事件。应从包含每个场景名称的字典中选择随机事件（也是随机的）。相反，它不会尝试访问其他场景。它只按照所写的顺序运行每个方法（函数？）。我做错了什么？这是一个糟糕的方式吗

我还在学习，所以任何指点都很感激

来自随机导入randint
从时间上导入睡眠
类随机事件（对象）：

#插入艺术
打印“\n对不起，我有一个不寻常的请求。”
打印“我的星座告诉我这是我的幸运日，”
打印“但我没有钱。”
打印“\n如果你让我借点钱，我”
打印“承诺给你一半的奖金。”
打印“我们达成协议了吗？”
给钱=原始输入（“（y）es或（n）o？”）
如果给你钱。下（）=“y”：
打印“\n资金：$”，self.wallet
how_mound=int（原始输入（“你会给多少钱？$”）
如果在创建字典时调用了多少函数：

scene_list = {1: story.old_man(), 2: story.robber(), 3: story.pretty_woman()}

由于希望
场景列表[1]
引用函数，请传递函数：

scene_list = {1: story.old_man, 2: story.robber, 3: story.pretty_woman}

我明白了，“（）”应该放在我想调用函数的地方？ie在“场景列表[2]之后”
