register cleanup handler

I have code like:

if (condition):
  do_something_needing_cleanup

code_executed_unconditionally

<cleanup has to happen here if required, even if above did return, continue 
or exception>

Now, how can I make sure cleanup happens?  Actually, what I really would 
like, is:

if (condition):
  do_something_needing_cleanup
  register_scoped_cleanup (cleanup_fnc)

code_executed_unconditionally


So, any thoughts/hopes of python being able to do something like this?

I know we have try/finally, but I don't think that helps here, because
code_executed_unconditionally couldn't be inside the try.  Or am I missing 
something obvious?
