There are defaults for arguments that can be either positional or passed as
a keyword -- and there are keyword-only arguments. __kwdefaults__ is used
for keyword-only arguments, other defaults are stored in __defaults__:
>>> def f(a, b="kw", *, c="kwonly"): pass
...
>>> f.__kwdefaults__
{'c': 'kwonly'}
>>> f.__defaults__
('kw',)
