| 表格受密码保护时，我们修改数据Excel弹出“您试图更改的单元格或图表受保护，因而是只读的。 | |
| 若要修改受保护单元格或图表，请先使用‘撤消工作表保护’命令(在‘审阅’选项卡的‘更改’组中)来取消保护。 | |

I've written a simple Python class for creating daemons on unix/linux systems. It was pieced together for various other examples, mostly corrections to various Python Cookbook articles and a couple of examples posted to the Python mailing lists. It has support for a pidfile to keep track of the process. I hope it's useful to someone.
