Yeah, it's probably the wrong list; still, easy enough to answer... You want this: text_file = open(i, "a") to open the individual file, as opposed to: text_file = open(textlist, "a") which tries to open the whole list of filenames. Python cannot figure out how to turn the list into a single (unicode) filename, hence the error. As for your wanting to write files with new names: for txtfile in txtlist: f = open(txtfile, 'r') data = f.read() f.close() fnew = open(get_new_name(txtfile), 'w') fnew.write(data) fnew.write('\nHelp is on the way.') fnew.close() where get_new_name() or whatever is defined appropriately to transform the old name ('test1.txt', say) into 'test1_appended.txt'...
