一、程序功能

购物功能

 -输入工资

 -列出购物菜单

 -选择购物项目

  -选择的购物项目,金额小于工资,扣钱,加入购物车

  -选择的购物项目,金额大于工资,给出提示,买金额小的项目

  -此时输入quit,退出购物,列出购物清单,退出

二、流程图如下

技术分享

三、python代码

#!/usr/bin/env python

import sys

salary = int(raw_input(‘Please input your salary:‘))

products = [

  [‘Iphone‘,5800],

  [‘MacPro‘,12000],

  [‘NB Shoes‘,680],

  [‘Cigarate‘,48],

  [‘MX4‘,2500]

]

#create a shopping list

shopping_list = []

while True:

  for p in products:

    print products.index(p) ,p[0], p[1]

  choice = raw_input("\033[32;1mPlease choose sth to buy:\033[0m")

  if choice == ‘quit‘:

    print "You have bought below stuff:"

    for i in shopping_list:

      print ‘\t‘,i

    sys.exit(‘Goodbye!‘)

  if len(choice) == 0:continue

  if not choice.isdigit():continue

  choice = int(choice)

  if choice >= len(products):

    print ‘\033[31;1m Could not find this item\033[0m‘

    continue

  pro = products[choice]

  if salary >= pro[1]: #means you can afford this

    salary = salary - pro[1]

    shopping_list.append(pro)

    print "\033[34;1mAdding %s to shopping list, you have %s left\033[0m" % (pro[0], salary) 

  else:

    print ‘The price of %s is %s, yet your current balance is %s,so try another one!‘ %(pro[0],pro[1], salary)
