No, it does not work in Python 2.4. gi_frame can be None only in Python 2.5 and higher. Via "What’s New in Python 2.5" (http://docs.python.org/whatsnew/ 2.5.html): """ Another even more esoteric effect of this change: previously, the gi_frame attribute of a generator was always a frame object. It’s now possible for gi_frame to be None once the generator has been exhausted. """ Cheers, mk -- http://mail.python.org/mailman/listinfo/python-list
