What does this print?

def f():
    try:
        return 1
    finally:
        return 2

print(f())

finally always runs, even after a return in try.

If finally also contains a return, that second return replaces the first one, so f() returns 2. It can even hide exceptions.

That is why a return inside finally is considered a bug; recent Python versions warn about it.

Never return inside finally.
