Just two days ago I had the same qustion, and I got this as answer from
Raymond Hettinger:

Regarding your C question: I didn't do such a thing, but *list only makes
the items of list be used as distinct arguments - so its more a matter of
the function signature you're calling. I'm sure you'll find something about
variable list arguments somewhere - that means that you function looks like
this:

def foo(arg1, arg2, *args):
  ....
