为何打印不了list
#coding:utf-8
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
#下面定义一个特殊方法。
def __str__(self):
l=[self.name,self.gender,self.score]
return l
