Python3项目初始化5-->面向对象

18、面向对象--类和实例属性
创建一个类
class PerSon(object):
    def __init__(self, name , age):
        self.name = name
        self.age = age

    def get_name(self):
        return self.name

    def set_name(self, name):
        self.name = name
kk = PerSon('kk', 30)
print(kk.get_name())
kk.set_name("huahua")
print(kk.get_name())

19、面向对象--类和实例方法
猫狗大战练习
#encoding:utf-8
import random
class Cat(object):
    def __init__(self, name, blood=100):
        self.name = name
        self.blood = blood
    def get_blood(self):
        return self.blood
    def drop_blood(self, drop):
        self.blood -= drop
    def attack(self, rival):
        drop = random.randint(0, 20)
        rival.drop_blood(drop)
class Dog(object):
    def __init__(self, name, blood=100):
        self.name = name
        self.blood = blood
    def get_blood(self):
        return self.blood
    def drop_blood(self, drop):
        self.blood -= drop
    def attack(self, rival):
        drop = random.randint(0, 20)
        rival.drop_blood(drop)
wangwang = Dog("wangwang")
miaomiao = Cat("miaomiao", 120)
while True:
    wangwang.attack(miaomiao)
    if miaomiao.get_blood() <= 0:
        print(wangwang.name + ' is win.')
        break
    miaomiao.attack(wangwang)
    if wangwang.get_blood() <= 0:
        print(miaomiao.name + 'is win..')
        break

20、面向对象--私有属性和继承
