python - 建立网站的目录和文件列表

Question

对于外面的人来说，这可能是一件容易的事，也可能不是一件容易的事……

我正在尝试构建文件还原服务。我有一本看起来像这样的字典。

基本上......这是我发现可以恢复的数据的字典。所有文件（不确定目录）都将具有“版本”，这是该文件存在的版本列表。

我试图弄清楚如何将其转换为 HTML 数据，用户可以使用这些数据来选择他们想要恢复的文件的版本。（限制是每个文件一个版本恢复。

我从来没有建造过这样的东西，我也没有在搜索中找到任何东西。

我的详细信息中缺少什么？

我/认为/我正在寻找的是这样的东西......

- home
-- /michael
--- /Data
---- UpgradeToCentOS5
      □ Version: current
      □ Version: 09/10/12
---- basic_debian
      □ Version: current
---- deploy.tgz
      □ Version: current
---- firewall
      □ Version: current
---- legalholder.sh
      □ Version: current
---- lists
----- boothosts
       □ Version: current
[...]

我用它来产生类似你的例子的东西。
