Since assignment is a statement in Python, not an expression,
and since "def f" is an assignment that binds a function
object to the name "f", you can't do exactly what you've
asked for.

On the other hand, this should be about equivalent, though
it's not merely an expression:

f = lambda x, y: x + y
