作业题目: 购物车程序

作业需求:

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},
......
]

功能要求：

1、启动程序后，输入用户名密码后，让用户输入工资，然后打印商品列表

2、允许用户根据商品编号购买商品

3、用户选择商品后，检测余额是否够，够就直接扣款，不够就提醒

4、可随时退出，退出时，打印已购买商品和余额

5、在用户使用过程中， 关键输出，如余额，商品已加入购物车等消息

代码实现过程

goods = [
{"name": "电脑", "price": 1999},
{"name": "鼠标", "price": 10},
{"name": "游艇", "price": 20},
{"name": "美女", "price": 998},
{"name":"特斯拉","price":300000}
]
shopping_list = []
salary = input("please input your salary:")
if salary.isdigit():
    salary = int(salary)
    while True:
        for index,i in enumerate(goods):
         print(index,i)
        choice = input("请选择要购买的商品编号：")
        if choice.isdigit():
            choice = int(choice)
            if choice >= 0 and choice < len(goods):
                if salary >= int(goods[choice]["price"]):
                    salary -= int(goods[choice]["price"])
                    print("购买商品后您的余额为：%s" '\033[95m'%salary)
                    list = goods[choice]
                    shopping_list.append(list)
                else:
                    print("您的工资太低，请选择能够买的起的商品")
            else:
                print("输入的商品编号不存在")
        elif choice == 'q' or choice == 'Q':
            print("******************** shopping_list *******************")
            for index,i in enumerate(shopping_list):
                print(index,i)
            exit()
        else:
            print("请根据提示内容输入商品编号")
