class Person(object):

    def __init__(self,name,gender):

        self.name=name

        self.gender=gender

class Student(Person):

    def __init__(self,name,gender,score):

        super(Student,self).__init__(name,gender)

        self.score=score

        def __str__(self):

            return '(Student:%s,%s,%d)'%(self.name,self.gender,self.score)

            __repr__=__str__      

s=Student('Bob','male',88)

print(s)

请问一下大家，为啥我输出的结果是：<__main__.Student object at 0x000001E6FDB190F0>
