对python中类的继承与方法重写介绍

class 子类(父类):

     方法

class Animal:
    def eat(self):
       print("-----吃-------")
    def drink(self):
       print("-----喝--------")
class Dog(Animal):
     def drak(self):
       print("汪汪叫")
a=Animal()
a.eat()

 #调用被重写的父类的方法
 #1 必须加上self
 Dog.bark(self)
 #2
 super().bark()
