Posted 2020-12-25 solarzc

1.类的继承：

#/usr/bin/env
#coding = utf-8
class animal():
    def __init__(self,name):
        self.name=name
    def eat(self):
        print("%s eat food!" %self.name)

class cat(animal):
    def cry(self):
        print("%s miaomiao jiao" %self.name)

class dog(animal):
    def cry(self):
        print("%s wangwang jiao" %self.name)

cat1 = cat(‘小猫‘)
cat1.eat()
cat1.cry()

dog1 = dog(‘小狗‘)
dog1.eat()
dog1.cry()

结果：

小猫 eat food!
小猫 miaomiao jiao
小狗 eat food!
小狗 wangwang jiao
