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 = {

# 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)

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()
