购物车的简单实现（方式一）

本文主要是实现：商品的选择及添加到购物车，并与自己的总资产比较，最后结算

代码：

#!/usr/bin/env python# -*- coding:utf-8 -*-# author by lh

shopping=[]all_price=0countmoney=int(raw_input(‘请输入您的总资产：‘))print ‘您的总资产为:%s元‘% countmoneygoods=[{‘name‘:‘mouse‘,‘price‘:1999},       {‘name‘:‘keyboard‘,‘price‘:200},       {‘name‘:‘computer‘,‘price‘:3000},       {‘name‘:‘mouse pad‘,‘price‘:200}       ]for key,i in enumerate(goods):    print key,iwhile True:    inp=int(raw_input(‘请输入商品：‘))    shopping.append(goods[inp])    i = int(raw_input(‘请确认是否购买：(输入1结算，其他则继续选择)‘))    if i == 1:        print ‘您购物车中的商品如下：‘        print shopping        for item in shopping:            p=item[‘price‘]            all_price=all_price+p        if shopping[0][‘price‘] > countmoney:            print ‘您的资产不够，请充值！‘        else:            print ‘购买成功！‘        break    else:        print ‘请重新选择商品！‘

运行结果：
