This is, unfortunately, a FAQ:

You must use

try:
    try:
        <statements>
    except WhatEver:
        <statements>
finally:
    <statements>

This is due to the fact that try-except and try-finally are two
different constructs; there was a thread here not long ago, starting
with Message-ID <mailman.30.1087503791.18066.python-list at python.org>
(if you use a news server to access comp.lang.python).
