Thanks a lot. That works great. I can't belive how close I was in the end. Well that was the last lines of this application, so thanks a lot.
And thanks for the tip about the portability stuff. I can't belive I didn't think about that. Been writing to much in non portable languages and libs like DirectX lately.

Few observations. 1) Don't concatenate pathnames yourself use os.path.join, that makes your code portable. lexi_file = open(os.path.join(sys.path[0],"lexi",files), "r") 2) Start with an empty list and append your "lines" lists: files_and_lines=[] filenumber = 0 for files in file_names: fpath=os.path.join(sys.path[0]),"lexi", files) try: lexi_file = open(fpath, "r") files_and_lines.append(lexi_file.readlines()) except(IOError): print "Something went wrong trying to read the file:" print "'%s'" % fpath lexi_file.close() # Remember to close each file Now you have: files_and_lines[0][0] -> Line 1 of the first file files_and_lines[0][1] -> Line 2 of the first file . . . files_and_lines[0][n] -> Line n of the first file files_and_lines[1][0] -> Line 1 of the second file . . .
