 A physical line is a sequence of characters terminated by an end-of-line

-sequences can be used - the Unix form using ASCII LF (linefeed), the Windows

 When embedding Python, source code strings should be passed to Python APIs using
 the standard C conventions for newline characters (the ``\n`` character,
