python类相关，super调用父类被重写的方法

python类相关，super调用父类被重写的方法

简单的小实例：

# -*- coding: utf-8 -*-
class Person:
    def __init__(self,name):
        self.name=name
        self.email="[email protected]"
    def f(self):
        print("Person f",self.name)

class Girl(Person):  
    '''Girl继承了Person类'''
    def __init__(self,height):
        self.height=height
    
    def f(self):
        print(self.name,self.email,self.height)

class Girl2(Person):
    '''Girl继承Person类，并通过super()初始化继承的成员'''
    def __init__(self,name,height):
        super(Girl2,self).__init__(name)
        self.height=height
    def f(self):
        super(Girl2,self).f()
        print("Girl2 f",self.name,self.email,self.height)

if __name__=="__main__":
    p1=Person("asd")
    print(p1.name)
    print(p1.email)
    
    '''p2=Person("asdf","123@123") 报错，无法通过传参初始化email属性'''
    
    g1=Girl(100)
    '''
    g1.f()    调用报错，因为__init__()方法被覆盖，Girl无法继承属性name,email
    print(g1.email) 因为__init__()方法被覆盖，Girl无法继承属性name,email 'Girl'，执行报错 object has no attribute 'email' 
    '''
    g2=Girl2("girl2",100)
    g2.f()
    

运行结果：

asd
[email protected]
Person f girl2
Girl2 f girl2 [email protected] 100
