在子类中重用父类的方法或属性

# 在子类派生出的新的方法中重用父类的方法，有两种实现方式
# 方式一：指名道姓（不依赖继承）
# 方式二： super（）（依赖继承）并且super 是按照mro顺序找的

# 方式一：
class Hoer:
    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 Garen(Hoer):
    camp = 'Demacia'
    def __init__(self,nickname,life_value,aggresivity,weapon):
        Hoer.__init__(self,nickname,life_value,aggresivity) # 指名道姓
        self.weapon = weapon

    def attack(self, enemy):
        Hoer.attack(self, enemy)  # 指名道姓
        print('from Garen Class')

class Riven(Hoer):
    camp = 'Noxus'

g1 = Garen('草丛伦',100,30,'金箍棒')
r1 = Riven('可爱的锐雯',80,50)

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

# 方式二：

class Hoer:
    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 Garen(Hoer):
    camp = 'Demacia'
    def __init__(self,nickname,life_value,aggresivity,weapon):
        super().__init__(nickname,life_value,aggresivity)
        self.weapon = weapon

    def attack(self, enemy):
        print('from Garen Class')

class Riven(Hoer):
    camp = 'Noxus'


g1 = Garen('草丛伦',100,30,'金箍棒')
r1 = Riven('可爱的锐雯',80,50)

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


# -----------------------
class A:
    def f1(self):
        print('form class a')
        super().f1()


class B:
    def f1(self):
        print('form class b')

class C(A,B):
    pass

print(C.mro())
'''
<class '__main__.C'>
<class '__main__.A'>
<class '__main__.B'>
<class 'object'>
'''
c = C()
c.f1()
# super 继承是按照mro 顺序找的
