子类中执行父类中的方法

示例

class Base(object):

    def func(self):
        print('Base.func')

class Foo(Base):

    def func(self):
        # 方式一：根据mro的顺序执行方法
        # super(Foo,self).func()
        # 方式二：主动执行Base类的方法
        Base.func(self)

        print('Foo.func')


obj = Foo()
obj.func()

'''
    Base.func
    Foo.func
'''

# 示例一
# obj = Foo()
# obj.func()
# '''
#     Bar.func
#     Base.func
# '''
# print(Foo.__mro__)  #(<class '__main__.Foo'>, <class '__main__.Base'>, <class '__main__.Bar'>, <class 'object'>)

# 示例二
# obj = Base()
# obj.func()    #报错 Base父类Object中无func方法
