The Python Script can use "getObject" in the same way as the ZPT, e.g.

    ....
    return [x.getObject() for x in Catalog(queryspec)]


Note, that "getObject" is a potentially expensive operation.
You would not like to call it on hundreds/thousands of objects
(especially not, when you later use only a handful).
