You can combine the two except clauses like:

```python
except (peer_api.PeerAssessmentRequestError , peer_api.PeerAssessmentInternalError) as err:
    return {
        'success': False,
        'msg': unicode(err)
    }

return {
    'success': True,
    'msg': _(u"Feedback saved!"),
}
```

Note that in the original code, `msg` is an exception object, not a string. So we should explicitly make it a string before passing it back.

Also, do we really want to bubble up the internal error specifics? As opposed to giving something more specific?
