    ip,cred,sn,st,phn in list:         w_sheet.write(row,0,ip)         w_sheet.write(row,2, cred )         w_sheet.write(row,3, sn)         w_sheet.write(row,5,st)         w_sheet.write(row,4,phn)         row += 1

here 0,2,3,5,4 column number, data written excel sheet based on column number. xlrd import open_workbook xlutils.copy import copy

book = open_workbook(r'testdata_new_modified.xls') sheet = book.sheet_by_index(1) wb= copy(book) w_sheet  = wb.get_sheet(1) dict_list=[] keys = [sheet.cell(0, col_index).value col_index in range(sheet.ncols)] in keys:     print     #w_sheet.write(sheet.nrows,i,list[i])     d={}     row_index in range(1, sheet.nrows):         d = {keys[col_index]: sheet.cell(row_index, col_index).value                 col_index in xrange(sheet.ncols)}         dict_list.append(d)     le in range(0,len(dict_list)):         data=dict_list[le][i]     print data     list = (      ['100.98.23.22', 'admin2', 'sn1','e1','9900'],      ['100.33.44.5',  'admin3',  'sn3','e3','8888'],      ['100.44.55.66', 'admin4','sn4','e4','9999'])     row= sheet.nrows     ip,cred,sn,st,phn in list:         w_sheet.write(row,0,ip)         w_sheet.write(row,2, cred )         w_sheet.write(row,3, sn)         w_sheet.write(row,5,st)         w_sheet.write(row,4,phn)         row += 1     #to write data excel sheet wb.save('testdata_new_modified.xls')

android - InAppBilling registering BroadcastReceiver in AndroidManifest -
