Forget about re and slicing and blind guessing... item appears to be a tuple; in these cases repr is your friend. See what happens with: print repr(item), type(item) If it is in fact a tuple, you should ask *why* is it a tuple (maybe could have many items?). And if it's just an artifact and actually it always will be a single: assert len(item)==1 item = item[0] if item... -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
