The string method
join, takes a sequence of string objects and joins them together in a single string:
>>> ', '.join( ('one', 'two', 'three') ) 'one, two, three' >>> print('\n'.join(reversed(['one', 'two', 'three']))) three two one >>> ' '.join('hello') 'h e l l o'
Recall that strings are themselves iterable sequences,so the last statement joins the letters of
'hello' with a single space.
