super() : 获取当前类的父类

效果图：

代码：

class Animal:
    def __init__(self,name):
        self._name = name

    @property
    def name(self):
        return self._name

    @name.setter
    def name(self,name):
        self._name = name

class Dog(Animal):
    def __init__(self,name,age):
        # super()获取当前类的父类
        #    并且通过super()返回对象调用父类方法时，不需要传递self
        super().__init__(name)   # 替换这个 self._name = name
        self._age = age
        
    @property
    def age(self):
        return self._age

    @age.setter    
    def age(self,age):
        self._age = name 

d = Dog(‘001‘,19)
print(d.name)
print(d.age)
