python_面向对象——多继承

1.多继承

class Shenxian:
    def fly(self):
        print('神仙会飞~')

class Monkey:
    def eat_peach(self):
        print('猴子喜欢吃桃子')
# 继承多个类
class MongkeyKing(Shenxian,Monkey):
    def play_stick(self):
        print('孙悟空玩金箍棒')

m = MongkeyKing()
# 子类对象可以执行多个父类中的方法
m.play_stick()
m.fly()
m.eat_peach()

 

 2.多继承顺序（按顺序从左到右继承）

class Shenxian:
    def fly(self):
        print('神仙会飞~')
    def fight(self):
        print('神仙打架')

class Monkey:
    def eat_peach(self):
        print('猴子喜欢吃桃子')
    def fight(self):
        print('猴子打架')
# 当多继承父类中同时有两个重名方法时，先继承左边父类中发方法（继承顺序从左到右）
class MongkeyKing(Shenxian,Monkey):
    def play_stick(self):
        print('孙悟空玩金箍棒')

m = MongkeyKing()
m.fight()

3.查看多继续顺序

class Base:
    def fight(self):
        print('祖先在打架')

class ShenxianBase(Base):
    def fight(self):
        print('神仙始祖们打架')
class Shenxian(ShenxianBase):
    def fly(self):
        print('神仙会飞~')
    def fight(self):
        print('神仙打架')

class MongekBase(Base):
    def eat(self):
        print('。。。')
    def fight(self):
        print('猿猴打架')

class Monkey(MongekBase):
    def eat_peach(self):
        print('猴子喜欢吃桃子')
    def fight(self):
        print('猴子打架')

class MongkeyKing(Monkey,Shenxian):
    def play_stick(self):
        print('孙悟空玩金箍棒')

m = MongkeyKing()
m.fight()
# 显示类的多继承顺序
print(MongkeyKing.mro())

　　将类的继承顺序放在列表中顺序排放。
