python中重写与调用方法是什么

class Cat(object):

    def sayHello(self):

        print("Hello:Cat")

class Bosi(Cat):

    def sayHello(self):

        print("Hello:Bosi")

bs = Bosi()

bs.sayHello()

Hello:Bosi

class Cat(object):

    def __init__(self,name):

        self.name = name

        self.color = "黄色"

class Bosi(Cat):

    def __init__(self,name):

        #Cat.__init__(self,name) #python2的语法

        #调用父类的方法

        super().__init__(name)

        def getName(self):

            return self.name

        pass

bs = Bosi("波斯")

print(bs.name)

print(bs.color)
