Supplying 2 arguments to 3-argument function - valtih - Sep-10-2017
I have the following piece of code
def visit(self, path, rootf, extraf): return extraf(path, path.parent().visit(rootf, extraf))I wonder how can it work if function visit takes 3 parameters but recursive call supplies only two.

The first parameter is
self, which is auto-populated with the current instance.

Maybe the parent is a different class, that only expects two parameters?
Otherwise, it wouldn't run, since there's no default values.
