abstractoperation.py?????????????????????????? //抽象操作類

代碼如下：

import string

class Operation(object):

def __init__(self):

pass

def init(self, num1, num2):

self.numA = string.atoi(num1)

self.numB = string.atoi(num2)

def Getresult():

pass

operation.py????????????????????????????????? //實現(xiàn)具體操作的類

代碼如下：

from abstractoperation import *

class OperationAdd(Operation):

def Getresult(self):

return self.numA + self.numB

class OperationSub(Operation):

def Getresult(self):

return self.numA - self.numB

class OperationMul(Operation):

def Getresult(self):

return self.numA * self.numB

class OperationDiv(Operation):

def Getresult(self):

if self.numB == 0:

return 'error'

return self.numA / self.numB

faction.py?????????????????????????????? //工廠類

代碼如下：

from operation import *

class Factory(object):

obj = None

def main(self, str):

if str == '+':

obj = OperationAdd()

elif str == '-':

obj = OperationSub()

elif str == '*':

obj = OperationMul()

elif str == '/':

obj = OperationDiv()

else:

pass

return obj

client.py??????????????????????????????????????????????????? //用來測試的客戶端程序

代碼如下：

#!/usr/bin/env python

from factory import *

num1 = raw_input('please input the first num:')

optType = raw_input('please input the operation type:')

num2 = raw_input('please input the second num:')

factory = Factory()

opt = factory.main(optType)

opt.init(num1, num2)

result = opt.Getresult()

print(result)

通過執(zhí)行客戶端程序就可以看到程序運行的結果，這里使用的python版本是2.7.5，對于python3來說，可能有點不同。。。。
