That doesn't work:

>>> print(_ if d.get('a', None) is not None else get_default())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name '_' is not defined

But this works:

>>> print(_ if (_ := d.get('a', None)) is not None else get_default())
1

(I would prefer ChrisA's solution, though.)
