python实现Excel删除特定行、拷贝指定行操作

工作中遇到的，本来用VBA写的，操作很慢，尝试用Python实现，

任务需求：

从原始的两张表中拷贝行到五张表中，如下表所示：

source1和source2是一样的格式：

				one		two		three		four		five
1	2	3		11	11	22	22	33	33	44	44	55	55

目标表格有one,two,three,four,five。

将前三列和对应表的两列拷贝到目标表格中，目标表格中原始也需要删除有关键字的行(注释代码中实现了，但是有8000多行，删除很耗时，改为了手动删除)，然后把source1和source2含有同样关键字的行拷贝过来，拷贝的列索引是固定的

实现：

采用xlrd读Excel，xlutils写Excel，注释中用win32com删除行(需要安装模块pip install pywin32)

#! /usr/bin/env python
# encoding:utf-8
import os
import xlrd
from xlutils.copy import copy
import win32com.client as win32
'''
文件名、修改的表名、查找的字符串固定，如有变化，则相应修改
'''
regstr = ['str1', 'str2']
tarExcels = ['one.xls','two.xls','three.xls','four.xls','five.xls']
tarSheet = 'targetSheet'
sourceExcels =['source1.xlsm','source2.xlsm']

    for item in sourcefiles:
