### 列表插件python用法，转载参考
```python
#参考代码:
##****************************保存服务插件*******************
#引入clr运行库
import clr
#添加对cloud插件开发的常用组件的引用
clr.AddReference('System')
clr.AddReference('System.Data')
clr.AddReference('Kingdee.BOS')
clr.AddReference('Kingdee.BOS.Core')
clr.AddReference('Kingdee.BOS.App')
clr.AddReference('Kingdee.BOS.DataEntity')
clr.AddReference('Kingdee.BOS.Contracts')
clr.AddReference('Kingdee.BOS.ServiceHelper')
#导入cloud基础库中的常用实体对象（分命名空间导入，不会递归导入）
