Python has short-circuiting logical operations, so one way to get the behavior
you're looking for is:
D.get('a') or get_default()
That will call get_default for any falsey value (0, "", an empty list ...),
not just for missing values.
Which may or may not be what the OP wants.
Good point, thanks for clarifying.
