有時候我們的表單可能很簡單，只是一個簡單交互的表單，但有可能還是要勞師動眾的給它建個工程寫個插件，是不是很不爽？例如我有如下一個表單：

功能很簡單就是選個業務對象，收集綁定幾個字段名，然后確定返回一個對象而已。我不想寫插件，因為K3Cloud是基于.net 4.0的，它對動態語言有了支持，于是我選擇使用python來實現這個簡單邏輯，以下是我的py插件，有注釋，小伙伴們應該讀得懂：

如果沒有LUTAI.K3.BOS.Core.DLL文件的話，可能會報錯：Could not add reference to assembly LUTAI.K3.BOS.Core，可以先刪掉。

我順便發個py編譯的小工具，小工具依賴cloud產品類庫，所以請放到ide臨時目錄里執行或者website\bin目錄下執行，本來讓sp2在這個編輯窗口上加個編譯按鈕，常見的語法錯誤都能查出來，不知sp2出來后為啥沒有，可能是在3.0里做了。
