python面向对象

用animal举例代码如下：

class Animal:
    name = ''
    age = 0

    def call(self):
        print('I am %s, and I\'m %d years old.' % (self.name, self.age))
    
    def isMe(self, name) -> bool:
        return self.name == name
    
animal = Animal()
animal.name = 'coco'
animal.age = 10
animal.call()

print(animal.isMe('coco'))

class Dog(Animal):
    score = 0 # 驯养成度

    def call(self):
        super().call()
        print("and my score is {}".format(self.score))

dog = Dog()
dog.name = 'momo'
dog.age = 2
dog.score = 99
dog.call()
