1. class Student(object):
   
2.     def __init__(self, sid, name, score):
   
3.         self.sid = sid
   
4.         self.name = name
   
5.         self.score = score
   
6. 
   
7.     def get_average_scores(self):
   
8.         return "平均成绩:%.1f" % (sum(self.score.values()) / 3)
   
9. 
   
10.     def get_info(self):
    
11.         return "学号:%s\n姓名:%s\n成绩:%s" % (self.sid, self.name, self.score)
    
12. 
    
13.     def __str__(self):
    
14.         return self.get_info()
    
15. 
    
16. if __name__ == '__main__':
    
17.     xiaoming = Student("66", "小明", {"语文": 90, "数学": 80, "英语": 70})
    
18.     print(xiaoming.get_info())
    
19.     print(xiaoming.get_average_scores())
    
20.     print(xiaoming)
