用Python完成购物车简单操作

products=[["iphone",6888],["macpro",14800],["小米6",2499],["coffee",31],["Book",60],["Nike",699]]
print("————————商品列表——————————")
i = 0
for product in products:
    print(i,end="\t")
    print(product[0],end="\t")
    print(product[1],end="\t")
    print("\r")
    i=i+1
shopping_car=[]
while 1:
    user=input("请选择你要买的东西，填写序号即可(按q结账)")
    if user!="q" and 0<=int(user)<=5:
        user=int(user)
        shopping_car.append(products[user][0])
        print("请问还需要其他东西吗？")
    elif user=="q":
        print("你购买的东西有：",end="")
        for i in shopping_car:
            print(i,end="、")
        break
    else:
        print("你输入的序号不存在，请重新输入")
