day24-python之面向对象
1.面向对象
1 # name='元昊' 2 # 3 # gender='母' 4 # 5 # type='藏獒' 6 7 #狗的特征 8 dog1={ 9 'name':'元昊', 10 'gender':'母', 11 'type':'藏獒' 12 } 13 dog2={ 14 'name':'alex', 15 'gender':'母', 16 'type':'腊肠', 17 } 18 dog3={ 19 'name':'hb', 20 'gender':'母', 21 'type':'哈士奇' 22 } 23 person1={ 24 'name':'武sir', 25 'gender':'母', 26 'type':'人' 27 } 28 29 person2 = { 30 'name':'流水', 31 'gender':'母', 32 'type':'狗' 33 } 34 35 36 def dog(name,gender,type): 37 # 狗的动作 38 def jiao(dog): 39 print('一条狗[%s]，汪汪汪' % dog['name']) 40 def chi_shi(dog): 41 print('一条[%s] 正在吃屎' % dog['type']) 42 dog1 = { 43 'name':name, 44 'gender': gender, 45 'type': type, 46 'jiao':jiao, 47 'chi_shi':chi_shi, 48 } 49 return dog1 50 # d1=dog('元昊','母','中华田园犬') 51 # d2=dog('alex','母','藏敖') 52 # print(d1) 53 # print(d2) 54 # d1['jiao'](d1) 55 # d2['chi_shi'](d2) 56 57 58 # def dog(name,gender,type): 59 # # 狗的动作 60 # def jiao(dog): 61 # print('一条狗[%s]，汪汪汪' % dog['name']) 62 # def chi_shi(dog): 63 # print('一条[%s] 正在吃屎' % dog['type']) 64 # def init(name,gender,type): 65 # dog1 = { 66 # 'name':name, 67 # 'gender': gender, 68 # 'type': type, 69 # 'jiao':jiao, 70 # 'chi_shi':chi_shi, 71 # } 72 # return dog1 73 # return init(name,gender,type) 74 # 75 # d1=dog('元昊','母','中华田园犬') 76 # d2=dog('alex','母','藏敖') 77 # print(d1) 78 # print(d2) 79 # d1['jiao'](d1) 80 # d2['chi_shi'](d2)
2.面向对象设计练习

3.面向对象展示
1 #用面向对象编程独有的语法class去实现面向对象设计 2 class Dog: 3 def __init__(self,name,gender,type): 4 self.name=name 5 self.gender=gender 6 self.type=type 7 8 def bark(self): 9 print('一条名字为[%s]的[%s],狂吠不止' %(self.name,self.type)) 10 11 def yao_ren(self): 12 print('[%s]正在咬人' %(self.name)) 13 14 def chi_shi(self): 15 print('[%s]正在吃屎' %(self.type)) 16 17 18 dog1=Dog('alex','female','京巴') 19 # print(dog1.__dict__) 20 dog2=Dog('wupeiqi','female','腊肠') 21 dog3=Dog('yuanhao','female','藏獒') 22 # 23 dog1.bark() 24 dog2.yao_ren() 25 dog3.chi_shi()
