Description

help(statistics.reduce)

reduce(function, iterable[, initial]) -> value

Apply a function of two arguments cumulatively to the items of a sequence
or 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).  If initial is present, it is placed before the items
of the iterable in the calculation, and serves as a default when the
iterable is empty.
