@ -280,14 +280,14 @@ The :mod:`functools` module defines the following functions:
.. function:: reduce(function, iterable[, initializer])
Apply *function* of two arguments cumulatively to the items of *sequence*, from
left to right, so as to reduce the sequence to a single value. For example,
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.
