python - Why doesn't `finally: return` propagate an unhandled exception? -

this question has answer here:

• python try-finally 1 answer

why function not raise exception? it's apparently not caught.

def f():     try:         raise exception     finally:         return "ok"  print(f())  # ok 

this explicitly explained in the documentation:

if exception occurs in of clauses , not handled, exception temporarily saved. finally clause executed. [..] if finally clause executes return or break statement, the saved exception discarded
