python3.x多继承顺序

大家是不是还在为3.x的python多继承顺序感到苦恼，今天为大家带来多继承的实战例子

class BaseClass:
    def show(self):
        print("BaseClass")


class SubClassA(BaseClass):
    def show(self):
        print("Enter SubClassA")
        super().show()
        print("Exit SubClassA")


class SubClassB(BaseClass):
    def show(self):
        print("Enter SubClassB")
        super().show()
        print("Exit SubClassB")


class SubClassC(SubClassA):
    def show(self):
        print("Enter SubClassC")
        super().show()
        print("Exit SubClassC")


class SubClassD(SubClassB,SubClassC):
    def show(self):
        print("Enter SubClassD")
        super().show()
        print("Exit SubClassD")


D = SubClassD()
D.show()
print(SubClassD.mro())

执行结果
Enter SubClassD
Enter SubClassB
Enter SubClassC
Enter SubClassA
BaseClass
Exit SubClassA
Exit SubClassC
Exit SubClassB
Exit SubClassD
[<class '__main__.SubClassD'>, <class '__main__.SubClassB'>, <class '__main__.SubClassC'>, <class '__main__.SubClassA'>, <class '__main__.BaseClass'>, <class 'object'>]
