简易购物程序的实现。（一种方式）
1 # 简易购物程序 2 3 money = 20000 4 goods_list = ['IPhone 8', 'Bicycle', 'Banana', 'Xiaomi Note', 'MacBook', '矿泉水'] 5 goods_price = [9000, 800, 20, 3200, 12000, 5] 6 print("欢迎来到智能购物中心！您卡上余额共有%d元。"% money) 7 print() 8 print('商品信息：') 9 count = 0 10 while count < len(goods_list): 11 print('商品编号:%d' % count + " " + goods_list[count] + '----' + str(goods_price[count]) + '元',end=" ") 12 count += 1 13 print() 14 flag = True 15 buy_lists = [] 16 buy_price = [] 17 while flag: 18 print() 19 num = input("请输入要购买商品的编号：") 20 print() 21 if num.isdigit() and int(num) < len(goods_list): 22 num = int(num) 23 if num < len(goods_list) and money >= goods_price[num]: 24 money -= int(goods_price[num]) 25 print("您购买了%s" % goods_list[num], '剩余%d元' % money) 26 buy_lists.append(goods_list[num]) 27 buy_price.append(goods_price[num]) 28 else: 29 print("余额不足！") 30 flag = False 31 else: 32 print("请输入正确的商品编号！") 33 print() 34 for m in range(len(buy_lists)): 35 buy_lists[m] += '--' + str(buy_price[m]) + '元' 36 print("您共购买了%d件商品：%s" % (len(buy_lists),' , '.join(buy_lists)) + ' ' + '您卡上剩余%d元' %(money) + ' ' + '欢迎下次光临！')
运行结果：

运行结果：
目前能力不足，以上两种方式都有很多不足之处，继续努力！
