Python之类和函数的综合应用

1. 程序

定义一个类，描述美女。

属性：

1、 姓名

2、 年龄

3、 体重

4、 电话

5、 家庭住址

6、 余额

7、 等等

方法：

1、 消费购物：随着购物的增加，余额减少

2、 吃零食，体重增加

3、 等等

初始化的时候，家庭住址默认是 未知

打印美女对象的时候，打印美女的所有信息

class Mm:

def __init__(self,name,age,weight,tel,balances,address='未知'):

self.name = name

self.age = age

self.weight = weight

self.tel = tel

self.address = address

self.balances = balances

def __str__(self):

msg = '姓名:%s|年龄:%s|体重:%s|电话:%s|家庭住址:%s|余额:%s '

%(self.name,self.age,self.weight,self.tel,self.address

,self.balances)

return msg

#购物消费的金额

def shopping(self,balance):

m = int(self.balances)

if m>balance:

m -= balance

self.balances = m

else:

print('余额不足!!!无法购物。。。')

#吃零食，kg表示将要增加的体重

def eat(self,junk_food,kg):

self.weight += kg

xiaohong = Mm('小红',20,100,12306,10000)

xiaohong.shopping(2000)

xiaohong.eat('吃喝',10)

print(xiaohong)

2. 程序

独立自己写出烤地瓜案例。

class Cordura(object):

def __init__(self,times=0,range='还没有入炉',spices=None):

spices = []

self.times = times

self.range = range

def __str__(self):

msg = '地瓜已经烧烤:%s分钟,状态:%s,口味:%s'%(self.times,self.range,self.spices)

return msg

def cor(self,ms):

self.times += ms

if self.times <= 3:

self.range = '别急客官，地瓜还是生的!!!'

elif self.times <= 6:

self.range = '马上就好，地瓜已经半熟了!!!'

elif self.times <= 10:

self.range = '已经熟了,客官您慢用!!!'

else:

self.range = '不好意思客官，厨师是个新来的，烤砸了!!!'

def sp(self,spice):

self.spices.append(spice)

self.spices = ','.join(self.spices)

guest = Cordura()

guest.cor(8)

guest.sp('沙拉味')

print(guest)

2.存放家具的案例

class family:

def __init__(self,area,furnitures=None):

furnitures = []

self.area = area

self.furnitures = furnitures

def __str__(self):

m=''

k=self.area

if(len(self.furnitures)>0):

for n in self.furnitures:

m = m + n.name + '大小:' + str(n.acreage)

k += n.acreage

msg = '家中总面积:%s剩余面积是:%s 放进家具有:%s'%(k,self.area,m)

return msg

def put_the_furniture(self,furniture):

if self.area > furniture.acreage:

self.furnitures.append(furniture)

self.area -= furniture.acreage

print('存放完成!!!')

else:

print('家中空间不足，放不下啦!!!')

class suite:

def __init__(self,name,acreage):

self.name = name

self.acreage = acreage

def __str__(self):

return '家具:%s,该家具所占面积:%s'%(self.name,self.acreage)

ww = family(120)

zz = suite('电脑桌',40)

zz1 = suite('大床',10)

ww.put_the_furniture(zz)

ww.put_the_furniture(zz1)

print(ww)
