While the explaination on __nonzero__ is useful out of this context, how can list be a generator? I am assuming that none are confusing the terminologies. In practical cases for testing boolean in lists, just use the list as the test. Empty list is false. -- Senthil _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
