If you’re just wrapping or filling one or two text strings, the convenience functions should be good enough; otherwise, you should use an instance of TextWrapper for efficiency. ''' >>> import textwrap >>> for line in (textwrap.wrap(sample_text, width = 50)): print (line) The textwrap module provides some convenience functions, as well as TextWrapper class that does all the work.
