No return to the parent function

[Joan Miller]

I've a main function called i.e. *foo()* which has a block of code
that is repetead several times (for the error catching code and error
reporting), but that code has a return to exit of *foo()*

-----------
foo():
  ...
    if self.background:
        _log.exception(str(error))
        return ReturnCode.ERROR, None
    else:
        raise NameError(error)

-----------

So I would tu put that code block into a separated function (*throw()
*), but the problem is that it returns to the parent function (foo()).
How to solve it?
