You suggest an interesting idea which triggered another idea... Are there mechanisms for using, accessing, executing the object id? objid = id(obj1) If so, I could set that as an attribute in the subsequent object when adding it as an attribute and then call it when values of that attribute changed. -- http://mail.python.org/mailman/listinfo/python-list
