 1 # 类
 2 class Role:
 3     def __init__(self, name, character, weapon, skills=10, life_value=10000, money=30000, level=99):
 4         # 构造函数，在实例化时做一些类的初始化工作
 5         self.name = name  # [[实例变量]]（静态属性）【变量】，作用域是实例本身
 6         self.character = character
 7         self.weapon = weapon
 8         self.life_value = life_value  # 私有属性——前面加两个杠，就不能在类的外部直接访问、更改了，类内部的方法仍可以访问
 9         self.money = money
10         self.level = level
11         self.skills = skills
12 
13     def __del__(self):
14         # 析构函数，做收尾工作
15         print("%s Completely Dead" % self.name)
16 
17 class Villan(Role):
18     def kill(self):
19         print("I am Thanos")
20 
21 class Avenger(Role):
22     A = "Infinity War"  # [[类变量]]
23     ‘‘‘类变量与实例变量
24     类变量存储实例共有的属性，实例变量存储各自特有的属性
25     所以若实例变量中出现了和类变量同名的变量，自然是优先访问实例变量
26     但并不通过将其设置为默认参数来给实例添加属性，因为类变量只需要一份存储空间
27     而实例变量则每次实例化都会占用一次存储空间‘‘‘
