编程练习-购物车程序开发

编程练习-购物车程序开发
根据以下数据结构：
goods = [
{“name”: “电脑”, “price”: 1999},
{“name”: “鼠标”, “price”: 10},
{“name”: “游艇”, “price”: 20},
{“name”: “美女”, “price”: 998},
…
]
实现功能要求：
1、启动程序后，让用户输入工资，然后进入循环，打印商品列表和编号

2、允许用户根据商品编号选择商品

3、用户选择商品后，检测余额是否够，够就直接扣款，并加入购物车， 不够就提醒余额不足

4、可随时退出，退出时，打印已购买商品和余额

goods = [{"name": "电脑","price": 1999},
        {"name": "鼠标", "price": 10},
        {"name": "游艇", "price": 20},
        {"name": '美女',"price": 998},
        {"name": '面', "price": 9}]
salary = int(input("请输入你的工资："))
balance = salary
shopping_cart =[]
for n, good in enumerate(goods):
    n += 1
    print(n, good)
while True:
    select_goodnum = int(input("请输入商品对应的编号："))
    if select_goodnum == 0:
        print("余额：%d，购买商品：%s"%(balance,shopping_cart))
        break
    else:
        if select_goodnum <= 5:
            select_good = goods[select_goodnum-1]
            print("选择货物%s" % select_good)
            shopping_cart.append(select_good)
            balance = balance - select_good['price']
            if balance < 0:
                print("余额不足")

        else:
            print("无此货物，请重新输入")
