python操作统计excel表格，生成新excel表格

0、前言

因产品的同学试着用python统计Excel表格，但百度的程序又一直有各种问题，所以叫我帮用python实现一个统计Excel表格程序；我之前也没有写过python操作Excel表格的程序，快速搜索实现了一下，还是发现一些问题，所以分享一下。

1、需求

我们使用TAPD管理项目，这里从TAPD导出的原Excel报表，统计后再生成的新Excel表。
原Excel报表是任务（标题）的信息列表，需要按需求分类分别统计各处理人的预估工时，如下（图1原始Excel表格有200多行、图2统计生成的新Excel表格）：

2、python操作excel表格说明

python操作excel表格有不少组件，如：xlwt、openpyxl、pandas、xlrd、xlwings

       一些组件在使用时有问题，如下：
               https://blog.csdn.net/weixin_42555985/article/details/102872781
               https://www.jianshu.com/p/8640abf11297

       这里选用xlwings，xlwings使用接近VBA的语法从Python自动与Excel交互，注意是使用到Excel软件；
       官方文档及一些参考如下：
               https://docs.xlwings.org/en/stable/index.html
               https://blog.csdn.net/whalefall/article/details/102665002
               http://www.dszhp.com/xlwings-range.html
               https://www.cnblogs.com/cyanrose/p/12059040.html
               https://blog.csdn.net/lh_hebine/article/details/104559382

       当然xlwing使用中也发现一个问题，range().expand()选择表格范围时无法识别一行/一列中的空值，遇到空值默认读取终止：
               https://blog.csdn.net/weixin_44781801/article/details/88692982
       下面程序会跳过一行/一列的范围选择问题。

3、python xlwings操作excel表格程序

目录下有111.py脚本、原始excel表格222.xls和生成的excel表格333.xls；

直接运行程序： $ python 111.py
即可实现222.xls --统计、生成--> 333.xls，效果如前面的excel表格图片；
下面是python 111.py脚本程序，可在python2.7运行:
