@ -154,15 +154,15 @@ The :keyword:`for` statement is used to iterate over the elements of a sequence
(such as a string, tuple or list) or other iterable object:
.. productionlist:: python-grammar
for_stmt: "for" `target_list` "in" `starred_list` ":" `suite`
for_stmt: "for" `target_list` "in" `starred_expression_list` ":" `suite`

The ``starred_list`` expression is evaluated once; it should yield an
:term:`iterable` object. An :term:`iterator` is created for that iterable.
The first item provided
by the iterator is then assigned to the target list using the standard
rules for assignments (see :ref:`assignment`), and the suite is executed. This
repeats for each item provided by the iterator. When the iterator is exhausted,
The :token:`~python-grammar:starred_expression_list` expression is evaluated
once; it should yield an :term:`iterable` object. An :term:`iterator` is
created for that iterable. The first item provided by the iterator is then
assigned to the target list using the standard rules for assignments

item provided by the iterator. When the iterator is exhausted,
the suite in the :keyword:`!else` clause,
if present, is executed, and the loop terminates.
