Out of range list index in python

import glob
import xlrd

from xlwt import Workbook

wb = Workbook()

for file_name in glob.glob("foo*.xls"):
    wb_orig = xlrd.open_workbook(file_name)
    for ws_orig in wb_orig.sheets():
        ws = wb.add_sheet('{0} {1}'.format(file_name, ws_orig.name))
        for rx in range(ws_orig.nrows):
            for cx in range(ws_orig.ncols):
                ws.write(rx, cx, ws_orig.cell_value(rx,cx))

wb.save("mefoo.xls")

I tried the above code in many ways to combine multiple excel sheets into one workbook ........ this code gives an error like

Traceback (most recent call last):
  File "E:\my python\Internship\mergestackoverflow.py", line 16, in <module>
    wb.save("mefoo.xls")
  File "C:\Python27\lib\site-packages\xlwt\Workbook.py", line 634, in save
    doc.save(filename, self.get_biff_data())
  File "C:\Python27\lib\site-packages\xlwt\Workbook.py", line 615, in get_biff_data
    self.__worksheets[self.__active_sheet].selected = True
IndexError: list index out of range

please help me resolve this error.

The only way to get this IndexError is if there are no sheets in the workbook.

You need to study yours glob.glob("foo*.xls"); it doesn't seem to return files.

I found a solution not to use the absolute path in glob.

for file_name in glob.glob("C://your//full//path//here//foo*.xls"):
  #population/merging code here

wb.save("mefoo.xls")

As to why this solved the problem, I don't know. But I hope this helps someone.
