定义锐雯类：
class Riven:
camp='Noxus'
def __init__(self,nickname,
aggressivity=54,
life_value=414,
money=1001,
armor=3):
self.nickname=nickname
self.aggressivity=aggressivity
self.life_value=life_value
self.money=money
self.armor=armor
def attack(self,enemy):
damage_value=self.aggressivity-enemy.armor
enemy.life_value-=damage_value
定义盖文类：
class Garen:
camp='Demacia'
def __init__(self,nickname,
aggressivity=58,
life_value=455,
money=100,
armor=10):
self.nickname=nickname
self.aggressivity=aggressivity
self.life_value=life_value
self.money=money
self.armor=armor
def attack(self,enemy):
damage_value=self.aggressivity-enemy.armor
enemy.life_value-=damage_value
定义装备：
class BlackCleaver:
def __init__(self,price=475,aggrev=9,life_value=100):
self.price=price
self.aggrev=aggrev
self.life_value=life_value
def update(self,obj):
obj.money-=self.price #减钱
obj.aggressivity+=self.aggrev #加***
obj.life_value+=self.life_value #加生命值
def fire(self,obj): #这是该装备的主动技能,喷火,烧死对方
obj.life_value-=1000 #假设火烧的***力是1000
测试交互：
r1=Riven('草丛伦')
g1=Garen('盖文')
b1=BlackCleaver()
print(r1.aggressivity,r1.life_value,r1.money) #r1的***力,生命值,护甲
if r1.money > b1.price:
r1.b1=b1
b1.update(r1)
print(r1.aggressivity,r1.life_value,r1.money) #r1的***力,生命值,护甲
print(g1.life_value)
r1.attack(g1) #普通***
print(g1.life_value)
r1.b1.fire(g1) #用装备***
print(g1.life_value) #g1的生命值小于0就死了
