day24-python之面向对象

1.面向对象

 # name='元昊'
 #
 # gender='母'
 #
 # type='藏獒'

 #狗的特征
 dog1={
     'name':'元昊',
     'gender':'母',
     'type':'藏獒'
 }
 dog2={
     'name':'alex',
     'gender':'母',
     'type':'腊肠',
 }
 dog3={
     'name':'hb',
     'gender':'母',
     'type':'哈士奇'
 }
 person1={
     'name':'武sir',
     'gender':'母',
     'type':'人'
 }

 person2 = {
     'name':'流水',
     'gender':'母',
     'type':'狗'
 }

 def dog(name,gender,type):
     # 狗的动作
     def jiao(dog):
         print('一条狗[%s]，汪汪汪' % dog['name'])
     def chi_shi(dog):
         print('一条[%s] 正在吃屎' % dog['type'])
     dog1 = {
         'name':name,
         'gender': gender,
         'type': type,
         'jiao':jiao,
         'chi_shi':chi_shi,
     }
     return dog1
 # d1=dog('元昊','母','中华田园犬')
 # d2=dog('alex','母','藏敖')
 # print(d1)
 # print(d2)
 # d1['jiao'](d1)
 # d2['chi_shi'](d2)

 # def dog(name,gender,type):
 #     # 狗的动作
 #     def jiao(dog):
 #         print('一条狗[%s]，汪汪汪' % dog['name'])
 #     def chi_shi(dog):
 #         print('一条[%s] 正在吃屎' % dog['type'])
 #     def init(name,gender,type):
 #         dog1 = {
 #             'name':name,
 #             'gender': gender,
 #             'type': type,
 #             'jiao':jiao,
 #             'chi_shi':chi_shi,
 #         }
 #         return dog1
 #     return init(name,gender,type)
 #
 # d1=dog('元昊','母','中华田园犬')
 # d2=dog('alex','母','藏敖')
 # print(d1)
 # print(d2)
 # d1['jiao'](d1)
 # d2['chi_shi'](d2)

2.面向对象设计练习

 def school1(name,addr,type):
     def init(name,addr,type):
         sch = {
             'name':name,
             'addr':addr,
             'type':type,
             'kao_shi':kao_shi,
             'zhao_sheng':zhao_sheng
         }
         return sch
     def kao_shi(school):
         print('%s 学校正在考试'%school['name'])
     def zhao_sheng(school):
         print('%s %s 正在招生'%(school['type'],school['name']))
     return init(name,addr,type)
 s1 = school1('将近','sb','肥猪')
 s1['zhao_sheng'](s1)
 def school(name,addr,type):
     def init(name, addr, type):
         sch = {
             'name': name,
             'addr': addr,
             'type': type,
             'kao_shi': kao_shi,
             'zhao_sheng': zhao_sheng,
         }
         return sch
     def kao_shi(school):
         print('%s 学校正在考试' %school['name'])
     def zhao_sheng(school):
         print('%s %s 正在招生' %(school['type'],school['name']))
     return  init(name,addr,type)

 # s1=school('oldboy','沙河','私立学校')
 # print(s1)
 # print(s1['name'])
 #
 # s1['zhao_sheng'](s1)
 #
 s2=school('清华','北京','公立学校')

 print(s2)
 print(s2['name'],s2['addr'],s2['type'])
 s2['zhao_sheng'](s2)

3.面向对象展示

 #用面向对象编程独有的语法class去实现面向对象设计
 class Dog:
     def __init__(self,name,gender,type):
         self.name=name
         self.gender=gender
         self.type=type

     def bark(self):
         print('一条名字为[%s]的[%s],狂吠不止' %(self.name,self.type))

     def yao_ren(self):
         print('[%s]正在咬人' %(self.name))

     def chi_shi(self):
         print('[%s]正在吃屎' %(self.type))

 dog1=Dog('alex','female','京巴')
 # print(dog1.__dict__)
 dog2=Dog('wupeiqi','female','腊肠')
 dog3=Dog('yuanhao','female','藏獒')
 #
 dog1.bark()
 dog2.yao_ren()
 dog3.chi_shi()

4.类相关知识

 # class Chinese:
 #     '这是一个中国人的类'
 #     pass
 #
 # print(Chinese)
 #
 # #实例化到底干了什么？
 # p1=Chinese() #实例化
 # print(p1)

 '''
 1.数据属性
 2.函数属性
 '''

 class Chinese:
     '这是一个中国人的类'
     dang='好'
     def sui_di_tu_tan():
         print('朝着墙上就是一口痰')
     def cha_dui(self):
         print('插到了前面')
 #
 # print(Chinese.dang)
 # Chinese.sui_di_tu_tan()
 # Chinese.cha_dui('元昊')
 #
 # print(dir(Chinese))
 # print(Chinese.__dict__) #查看属性字典
 # print(Chinese.__dict__['dang'])
 # Chinese.__dict__['sui_di_tu_tan']()
 # Chinese.__dict__['cha_dui'](1)
 # print(Chinese.__name__)
 # print(Chinese.__doc__)
 print(Chinese.__module__)

5.对象相关知识

 '''
 1.数据属性
 2.函数属性
 '''
 class Chinese:
     '这是一个中国人的类'

     dang='公司'

     # def __init__(name,age,gender):
     #     dic={
     #         'name':name,
     #         'age':age,
     #         'gender':gender

6.类属性增删改查

 class Chinese:
     country='China'
     def __init__(self,name):
         self.name=name

     def play_ball(self,ball):
         print('%s 正在打 %s' %(self.name))
 #查看
 # print(Chinese.country)

 #修改
 # Chinese.country='Japan'
 # print(Chinese.country)
 #
 p1=Chinese('alex')
 # print(p1.__dict__)
 # print(p1.country)
 #
 # #增加
 Chinese.dang='对的'
 # #
 # print(Chinese.dang)
 # print(p1.dang)
 #
 # #删除
 del Chinese.dang
 del Chinese.country
 #
 print(Chinese.__dict__)
 # print(Chinese.country)
 #
 #
 def eat_food(self,food):
     print('%s 正在吃%s' %(self.name,food))

 Chinese.eat=eat_food
 #
 # print(Chinese.__dict__)
 # p1.eat('屎')
 #
 #
 def test(self):
     print('test')

 Chinese.play_ball=test
 p1.play_ball()# Chinese.play_ball(p1)

7.实例属性增删改查

 class Chinese:
     country='China'
     def __init__(self,name):
         self.name=name

     def play_ball(self,ball):
         print('%s 正在打 %s' %(self.name,ball))
 p1=Chinese('alex')
 # print(p1.__dict__)

 #查看
 # print(p1.name)
 # print(p1.play_ball)

 #增加
 # p1.age=18
 # print(p1.__dict__)
 # print(p1.age)

 #不要修改底层的属性字典
 # p1.__dict__['sex']='male'
 # print(p1.__dict__)
 # print(p1.sex)

 #修改
 p1.age=19
 print(p1.__dict__)
 print(p1.age)
 #
 # #删除
 del p1.age
 print(p1.__dict__)
