+#从前啊，有三个bro，分别是：
+bro1="刘备"
+bro2="关羽"
+bro3="张飞"
+#他们来到了桃园准备结拜
+bros = ["刘备","关羽", "张飞"]
+#酒也准备好了，誓词也准备好了，得排个辈分，三人的信息卡是这样的：
+bro1=["刘备",161,9.1]
+bro2=["关羽",160,8.5]
+bro3=["张飞",166,8.3]
+#虽然呢，看起来关羽最年长，但是刘备的综合水平最强，所以，关羽一抱拳，甘为老二，刘备就成了大哥。
+#结拜，大哥自然得站在C位，所以把列表中的刘备替换为关羽，关羽替换为刘备：
+bros[0] = "关羽" 
+bros[1] = "刘备" 
+#这时打印出列表：
+print(bros)
+#辈分也排完了，三人顺利结拜，讲出誓言：念刘备、关羽、张飞，虽然异姓，既结为兄弟，则同心协力，救困扶危，上报国家，下安黎庶；不求同年同月同日生，只愿同年同月同日死。皇天后土，实鉴此心；背义忘恩，天人共戮！  这就是桃园结义的故事~

+#同时也可以说说以上都用到了列表的哪些知识：
+#列表的定义、列表的包容性、列表中元素的替换
