class Role(object):
    def __init__(self,name,role,weapon,life_value=100,money=15000):
        self.name = name
        self.role = role
        self.weapon = weapon
        self.life_value = life_value
        self.money = money
        self.aaa = 1

    def shot(self):
        print("shooting...")

    def got_shot(self):
        print("ah...,I got shot...")

#Role的实例
#把一个抽象的类变成一个具体的对象的过程
r1 = Role("wohaoshuai1","police","AK47")#生成一个角色
#相当于Role(p1,"wohaoshuai","police","AK47")

r2 = Role("wohaoshuai2","police","B22") #生成一个角色

r1.buy_gun("AK47") #会自动转换成Role.buy_gun(r1,"AK47")
