練習：編寫一個學生類，產生一堆學生物件
要求：有一個計數器（屬性），統計總共實力化多少個物件

class Student:
    school = 'luffycity'
    count = 0

    def __init__(self, name, sex, age):  # 獨有特徵
        self.Name = name
        self.Sex = sex
        self.Age = age
        Student.count += 1  # 核心，這樣是累加呼叫的次數；self.count 是物件自己一個 值為1

    def learn(self):  #
 
 技能
        print('is learning')




stu1 = Student("alex",'male',28)
stu2 = Student("egon",'male',18)
stu3 = Student("wusi",'male',27)

print(stu1.count)
print(stu2.count)
print(stu3.count)

練習2：模仿LOL定義兩個英雄類，
要求：

英雄有暱稱，攻擊力，生命值等屬性；
例項化兩個英雄物件
英雄之間可以互毆，被毆掉一方的掉血，血量小於0則判斷死亡。

class Garen:
    camp = 'camp
 
'

    def __init__(self,nickname,life_value,aggresivity):
        self.nickname=nickname
        self.life_value=life_value
        self.aggresivity=aggresivity

    def attack(self,enemy):
        enemy.life_value -= self.aggresivity


class Riven:
    camp = 'Noxus'

    def __init__(self,nickname,life_value,aggresivity):
        self.nickname
 
=nickname
        self.life_value=life_value
        self.aggresivity=aggresivity

    def attack(self,enemy):
        enemy.life_value -= self.aggresivity
        # if enemy.life_value <= 0:



g1=Garen('草叢倫',100,30)

r1=Riven('芮雯雯',80, 50)
print(r1.life_value)

g1.attack(r1)
g1.attack(r1)
g1.attack(r1)
print(g1.attack(r1))
print(r1.life_value)
