where did you look?  the obvious place should be under
"function definitions" in the language reference:

    http://www.python.org/doc/current/ref/function.html

    ...

    "If the form *identifier is present, it is initialized to a
    tuple receiving any excess positional parameters, defaulting
    to the empty tuple. If the form **identifier is present, it is
    initialized to a new dictionary receiving any excess keyword
    arguments, defaulting to a new empty dictionary."

    ...
