首先，这里的代码是受Head First Python的启发。瞄了1眼，看了mvc分离的思路以后。自己画了一张草图。

打算做1个我的书单演示web

最终效果

1：1个简单的index.py，显示所有书单列表

2：添加或删除书

3：点击一本书，查看内容

记录其中遇到的问题

1:cgi-bin执行需要权限 chmod +x [file or path]

2:cgi-bin执行的脚本文件头部需要加上环境#!/usr/bin/env python

否则，会提示run_cgi 权限错误

今天完成：

模型部分

简单的模版替换(string.Template模版)

首页简单打印一句话

运行截图:
