Sums \var{start} and the items of an \var{iterable} from left to
right and returns the total. \var{start} defaults to \code{0}.
The \var{iterable}'s items are normally numbers, and are not allowed
to be strings. The fast, correct way to concatenate a sequence of
strings is by calling \code{''.join(\var{sequence})}.
Note that \code{sum(range(\var{n}), \var{m})} is equivalent to
\code{reduce(operator.add, range(\var{n}), \var{m})}
