 Since this is typically only desired when reading text one line at a time, using
 ``S.rstrip()`` this way works well.
 
-For older versions of Python, there are two partial substitutes:
-
-- If you want to remove all trailing whitespace, use the ``rstrip()`` method of
-  string objects.  This removes all trailing whitespace, not just a single
-  newline.
-
-- Otherwise, if there is only one line in the string ``S``, use

 Is there a scanf() or sscanf() equivalent?
