Summary: Minor error in sum() docs
Initial Comment:
In 2.1 Built-in Functions, the docs for sum() say it takes a sequence argument.
IIUC the actual requirement is for an iterable which is a weaker requirement
than a sequence. For example the argument can be a generator expression or a
dict, neither of which is a sequence. Also there is a missing 'a' in the fourth
sentence.
Here is a suggested rewrite:
sum(iterable[, start])
Sums start and the items of an iterable, from left to right, and returns
the total. start defaults to 0. The iterable's items are normally numbers, and
are not allowed to be strings. The fast, correct way to concatenate a sequence
of strings...
