 This feature is particularly useful when you want to break long strings::
 
    >>> text = ('Put several strings within parentheses '
-               'to have them joined together.')
+   ...         'to have them joined together.')
    >>> text

 Slice indices have useful defaults; an omitted first index defaults to zero, an
 omitted second index defaults to the size of the string being sliced. ::

 One way to remember how slices work is to think of the indices as pointing
