标签：ice 休息 shel rom 成功 管理 append 讲师 上海 之前有一个关于选课的练习，一直没有给实现，趁着明天休息，琢磨一下给弄出来，本来以为今天能搞定，看来是我想多了。 先看一下文件分布吧 没啥可多说的，今天完成了一部分，剩下的明天搞定。 bin文件下： conf文件下的setting core文件下的main core文件下的school_view 关于logging模块、shelve模块，基本忘的差不多了，现在内容逐渐多了，复习貌似更重要，不能过于激进，争取端午节前实现自己的承诺。 Python学习第72天（复习：选课实现习题） 标签：ice 休息 shel rom 成功 管理 append 讲师 上海 原文地址：https://www.cnblogs.com/xiaoyaotx/p/12861410.html
