Elegant way of re-raise exception with finally part exists

I want to catch exception out of a function, while if finally part exists in the function, the outer part couldn't know exception exists.

Here is the code:

def f():
    l = []

    try:
        raise Exception('fake')
    except:
        raise e
    finally:
        return l

try:
    f()
except:
    print 'wrong'
else:
    print 'right'

Output is

right

And if I remove "finally" part, it will output wrong as expected.

I know the reason from here, but I don't know any elegant way to deal with this scenario, how should I write code if I need re-raise and finally together?

Other than not returning in `finally`? – Ignacio Vazquez-Abrams Dec 28 '15 at 07:42
thanks, so you mean "use return in finally part" is bad idea? – linpingta Dec 28 '15 at 07:44

you do know that finally always gets executed right? – mid Dec 28 '15 at 07:53
thanks for help guys, I think it's my wrong way of "finally" usage – linpingta Dec 28 '15 at 08:18
