python-super().__init__()

定义一个类，具有一个属性name

class Person:
    def __init__(self, name='Person'):
        self.name = name

1、继承时直接覆盖init方法，增加属性age，则Student不含name属性，输出name报错

class Student(Person):
    def __init__(self,age):
        self.age = age
lihua = Student(10)
print(lihua.age)
print(lihua.name)

 

 2、使用super().__init__()改写init()方法，增加一个属性age，此时构造的Student类可以调用name和age属性

class Student(Person):
    def __init__(self,age):
        super(Student,self).__init__()
        self.age = age

lihua = Student(10)
print(lihua.age)
print(lihua.name)
