构造函数的变量 也叫做 实例变量
class role(): # 传参数 def __init__(self,name,role,weapon,life_value=100,moneny=15000): # 构造函数 # 实例化过程中做一些类的初始化工作 self.name = name self.role = role self.weapon = weapon self.life_value = life_value self.moneny = moneny def shot(self): # 类的方法，功能（动态属性） print("shotting") def got_shot(self): print("on,%s got shoot..." % self.name) def buy_gun(self,gun_name): print("%s just bought %s" %(self.name,gun_name)) b1 = role('mike','police','AK47') b1.got_shot() # 调用 # on,mike got shoot... b1.buy_gun("B21") # mike just bought B21 b2 = role('ben','terrorist','AK47') b2.got_shot() # role.got_shot(b2) # on,ben got shoot... b2.buy_gun("B21") # ben just bought B21 b2.buy_gun("B46") # ben just bought B46 print(b2.weapon) # AK47
打印b2.weapon 还是AK47 部署B21 B46
