面向对象（metaclass继承高级用法）

方法一：
# class   MyType(type):
#     def  __init__(self,*args,**kwargs):
#         print('132')
#         super(MyType,self).__init__(*args,**kwargs)
#         ###执行父类的init方法
#
#
# class  Base(object,metaclass = MyType):####metaclass继承父类的
#     pass







方法二：
# class  Mytype(type):
#     def  __init__(self,*args,**kwargs):
#         print('23')
#         super(Mytype,self).__init__(*args,**kwargs)
# Base=Mytype('Base',(object,),{})



# class MyType1(type):
#     def   __init__(self,*args,**kwargs):
#         print('sdsd')
#         super(MyType1,self).__init__(*args,**kwargs)
#
# def  with_args(arg):
#     base=MyType1('Base',(arg,),{})
#     return  base
#
# class  FOO(with_args(object)):
#     pass
#
# FOO()









方法三：
class  FOO1(type):
    def  __init__(self,*args,**kwargs):
        print('223')
        super(FOO1,self).__init__(*args,**kwargs)
class  FOO2(metaclass=FOO1):
    pass
FOO2()
