super().__init__()的使用

“One should not forget to call super in order to implement the functionality of
the original class being overloaded. ”——Kivy官网
如：

#!/usr/bin/env python
# -*- coding:utf-8 -*-
 
class Person(object):
    def __init__(self,name,gender,age):
        self.name = name
        self.gender = gender
        self.age = age

class Student(Person):
    def __init__(self,name,gender,age,school,score)
	self.name = name.upper()  
        self.gender = gender.upper()
        self.school = school
        self.score = score

s = Student('Alice','female',18,'Middle school',87)
print (s.school)
print (s.name)

Output:
Middle school
ALICE

如果使用super(Student, self).init():

#!/usr/bin/env python
# -*- coding:utf-8 -*-
 
class Person(object):
    def __init__(self,name,gender,age):
        self.name = name
        self.gender = gender
        self.age = age
 
class Student(Person):
    def __init__(self,name,gender,age,school,score):
        super(Student,self).__init__(name,gender,age)
        self.school = school
        
s = Student('Alice','female',18,'Middle school',87)
print (s.school)
print (s.name)

Output:
Middle school
Alice
可见super().__init__()可以继承父类的初始化方式，也就是不只是运行子类，还运行了父类。
