python 继承

 一.源码

class lingzhanglei:
    def houzi(self):
        print("houzi is a zhizhang")

class heixingxing(lingzhanglei):
    def xingwei(self):
        print("heixx love qiaomimi")

class shuwukong(lingzhanglei):
    def shengfen(self):
        print("swk is douzhanshengfu")

renren = lingzhanglei()
renren.houzi()
# renren.xingwei()
print()

renren2 = heixingxing()
renren2.xingwei()
renren2.houzi()
# renren2.shengfen
print()

renren3 = shuwukong()
renren3.shengfen()
renren3.houzi()

二.结果

houzi is a zhizhang

heixx love qiaomimi
houzi is a zhizhang

swk is douzhanshengfu
houzi is a zhizhang

三.笔记

儿子可以用父亲的

父亲不能用儿子的

兄弟分家不互用
