Python 2.7 通过Python使用COM API阅读Excel工作表

我在前面使用过xlrd和xlwt，它们易于读取行和列。我正在将当前的excel读写代码（当前正在使用xlrd和xlwt）转换为excel com api

import win32com.client as win32
excel = win32.Dispatch('Excel.Application')
wbtemp = excel.Workbooks.Open(file path)
readtemp = wbtemp.Worksheets('Temp')
read_1 = readtemp.Cells(1,1)
print read_1
System User

used = readtemp.UsedRange
print used.Find('System User')
System User ## it shows System User is present in worksheet, wont give which cell

print used.Find('xyz')
None ## when its not found on worksheet

目前上述代码硬编码到单元格（1,1），但我正在寻找灵活的方法，如在工作表中搜索“系统用户”，并以单元格（1,1）的形式获得回复

import win32com.client as win32
excel = win32.Dispatch('Excel.Application')
wbtemp = excel.Workbooks.Open(file path)
readtemp = wbtemp.Worksheets('Temp')
read_1 = readtemp.Cells(1,1)
print read_1
System User

used = readtemp.UsedRange
a = used.Rows.Find('System User')
print a.Address
$A$1 ## Thats what I was looking for..
