python购物车

哈哈哈哈，怎么说呢，苦尽甘来吧，终于，购物车这个B东西，终于让老子搞出来了

money=int(input("please put you money:"))
print("you money is",money)
commodity=[["iphone",9000],
           ["huawei",8000],
           ["redmi",3000],
           ["oppo",2000]]
print,enumerate(commodity)
mmy=[]
a=""
while True:
    for i,k in enumerate(commodity):
        print(i,k)
    want_buy=int(input("please put you want buy:"))
    if want_buy<=3:
       if money>=commodity[want_buy][1]:
          sur=money-commodity[want_buy][1]
          mmy.append(commodity[want_buy])
          money=sur
          print("you want buy is:",mmy,"	"
             "The rest of money is:",sur)
          a=input("Keep pressing'y',Press 'n' at the end:")
          if a=="y":
           continue
          elif a=="n":
              break
              print("Sorry,your balance is insufficient")
              print("you want buy is:",mmy,"	"          
                 "The rest of money is:",money)          
              break                                      
       else:
           print("Sorry,your balance is insufficient")
           print("you want buy is:",mmy,"	"  
              "The rest of money is:",money)
           break
    else:
        print("Invalid input")
        break

这个是整个过程的代码，独一无二，这个和教程上是不同的，我也操作过，基本没什么问题，

3个小时的苦果，哈哈哈，虽然很耗时间，但是能做出来真的肯开心。
