'''
模拟cs游戏
人物角色分为警察和匪徒两种,定义成两个类
折有的警察的角色都是 police
每个警察都有自己独有名字,生命值,武器,性别
每个都可以开枪攻击敌人,且攻击目标不能是 police
所有的匪徒的角色都是 terrorist
每个匪徒都有自己独有名字,生命值,武器,性别
每个都可以开枪攻击敌人,切攻击目标不能是 terrorist
a.实例化一个警察,一个匪徒,警察攻击匪徒,匪徒掉血

16.自定义类
个圆形类,属性是半径,提供两个方法,计算圆周长和面积
实现如图的继承关系,然后验证经典类与新式类在查找一个属性时的搜索顺序
基于多态的概念来实现Liunx中一切皆文件的概念:文本文件,进程,磁盘都是文件,然后
验证多态性
ⅳv.定义老师类,把老师的属性:薪资,隐藏起来,然后针对该属性开放访问接口
V.定义如下类,并最大程度地重用代码(继承,派生:子类重用父类方法,组合,)老师
类学生类分数类课程类日期类
基于授权定制自己的列表类型,要求定制的自己的init方法。
ⅶi.定制自己的 append:只能向列表加入字符串类型的值
vi.定制显示列表中间那个值的属性(提示: property)
ⅸX.其余方法都使用is默认的(提示:_ getattr加反射)
