Or
result = bar()
if not result:
result = default
Seriously, what is the obsession with putting things on one line here?
If it's because "it works better when there is a long list of such
assignments" then unless you actually show a real-world example, it's hard
to discuss the *actual* trade-offs. And typically with a real-world
example, there are a lot more options available (for example, if this is
defaulting a series of arguments to a function, it's often an anti-pattern
to have a function with that many arguments in the first place, so
refactoring the code may be a better option).
