我想从继承的类中调用父对象的 call 方法

代码看起来像这样

#!/usr/bin/env python

class Parent(object):

    def __call__(self, name):
        print "hello world, ", name


class Person(Parent):

    def __call__(self, someinfo):                                                                                                                                                            
        super(Parent, self).__call__(someinfo)

p = Person()
p("info")

我明白了

File "./test.py", line 12, in __call__
super(Parent, self).__call__(someinfo)
AttributeError: 'super' object has no attribute '__call__'

我不知道为什么，有人可以帮我吗？
