I wrote the below code

    image_id = 123
    fixtures = []
    def add_fixture(**kwargs):
        kwargs.update(created_at=NOW_DATE, updated_at=NOW_DATE)
        fixtures.append(kwargs)
    add_fixture(id=str(image_id), name='public    image', is_public=True, status='active', properties={'key1': 'value1'}, min_ram='128', min_disk='10', size='25165824')
    image_id += 1
    uuid = 'aa640691-d1a7-4a67-9d3c-d35ee6b3cc74'
    snapshot_properties = {'instance_uuid': uuid, 'user_id': 'fake'}
    for status in ('queued', 'saving', 'active', 'killed', 'deleted', 'pending_delete'):
        deleted = (False if (status != 'deleted') else True)
        deleted_at = (NOW_DATE if deleted else None)
        add_fixture(id=str(image_id), name=('%s    snapshot' % status), is_public=False, status=status, properties=snapshot_properties, size='25165824', deleted=deleted, deleted_at=deleted_at)
        image_id += 1
    add_fixture(id=str(image_id), is_public=True, status='active', properties={})
    image_id += 1
    add_fixture(id=str(image_id), is_public=True, status='active', properties={}, owner='authorized_fake')
    return fixtures

What's a good function header?
