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:
基础要求:
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,需高亮显示
扩展需求:
1、用户下一次登录后,输入用户名密码,直接回到上次的状态,即上次消费的余额什么的还是那些,再次登录可继续购买
2、允许查询之前的消费记录
