documentation of arguments

[Skaperen]

But then again, the docs for 3.0's sorted do indicate that they're keyword only:

[quote="https://docs.python.org/3.6/library/func...tml#sorted"]sorted(iterable[, key][, reverse])
Return a new sorted list from the items in iterable.

Has two optional arguments which must be specified as keyword arguments.

my bad, reading the docs for sorted in version 2 and version 3 side by side seems to leave me confused.

and that feature of combing one-after-another posts to same thread with a long horizontal rule between them seems to leave the reply editing confused.  that long horizontal rule gets in the reply and can't be removed.
