xlutils.copy [python 2.7 - excel]

Question

I'm new to python (and to programming in general).

I am having a problem using xlrd, xlwt and xlutils for accessing an xlsx workbook (it is a common question but i did not find any solution for me).

Should I change my package for py-excel? In that case, which one?

Here is my code:

import xlrd
import xlwt
from xlutils.copy import copy as xlutils_copy

rd = xlrd.open_workbook("x:/PROJECTS/Papers/2014_Pasture/a.xlsx")
rdsh = rd.sheet_by_name("FR_PASTURE")

wrb = xlutils_copy(rd)
ws = wrb.get_sheet_by_name("FR_PASTURE")

And the error I am receiving:

Traceback (most recent call last):
  File "X:\PROJECTS\Papers\2014_Pasture\AdjustXLSStats.py", line 28, in <module>
    wrb = xlutils_copy(rd)

xlrd, xlwt, and xlutils are for accessing xls files, and have not been updated for use with xlsx files, which results in your multiple errors.

As a workaround, there is now a Python library openpyxlwhich can easily read and write Excel xlsx/xlsm/xltx/xltm files.
