Is this what you want to happen when port is None? >>> port = None >>> print (port != None) and '' or port None I think you're getting caught by the classic and/or trap in Python, trying to avoid using a simple if statement. By the way, equality comparison with None is generally a bad idea as well, so even if the above worked it should be (port is not None) rather than (port != None). -Peter -- http://mail.python.org/mailman/listinfo/python-list
