+   Apply *function* of two arguments cumulatively to the items of *iterable*, from
+   left to right, so as to reduce the iterable to a single value.  For example,
    ``reduce(lambda x, y: x+y, [1, 2, 3, 4, 5])`` calculates ``((((1+2)+3)+4)+5)``.
    The left argument, *x*, is the accumulated value and the right argument, *y*, is
-   the update value from the *sequence*.  If the optional *initializer* is present,
-   it is placed before the items of the sequence in the calculation, and serves as
-   a default when the sequence is empty.  If *initializer* is not given and
-   *sequence* contains only one item, the first item is returned.
