Passing default parameters into nested functions python

I have a function

foo(x, setting1=def1, settings2=def2)

(actually this is a third party library function with a bunch of default parameters of which I need to set only 1 externally, but for the sake of example..)

I am calling this from

bar(y, settings2_in=def2)
   x = get_x(y)
   foo(x, settings2=settings2_in)

This is ok, but stylistically I'd rather call name the parameter settings2_in settings2. When I keep passing another layer down, I'll have to keep renaming the parameter, and it gets ugly.

bletch(z, settings2_in_2=def2)
   y = get_y(z)
   bar(y, settings2_in=settings_in_2)

Is there a "nice"/Pythonic way to pass a subset of default parameters down many layers of functions in this way?

Is Python clever enough to work out that if I do:

bar(y, settings2=def2)
   x = get_x(y)
   foo(x, settings2=settings2)

That the 2 uses of settings2 are different from the context?
