The (n given) notice refers to the number of keyword parameters
you specified in the call that could be associated with a
non-keyword arguments of the function.
I agree that this is a bit misleading.
Please open a bug report on python.org.

You probably saw PEP 3102:
http://www.python.org/dev/peps/pep-3102/
That has a somewhat different focus though: it allows defining
keyword-only arguments, ie. ones that cannot be used as
both non-keyword parameter and keyword parameter (like we
have in Python 2.x).
