I don't think that 'efficient' and 'plainly' mean what you think they 
mean. However to answer your question:

     new_list[-1] if new_list else None

BTW I get the impression that the yield statement yields the whole 
pot_file_text list each time, so that new_list will be a list of lists; 
is that intentional?
