hello, maybe i know less python than you do, but i am talking from the point of view of my common sense and experience. if you store an object in a list more than once, i doubt that python creates a duplicate. unless the object is a value type. thus you have a reference to this object in both elements. and then if you are asking this question, maybe your design is not good enough? would you explain the problem? konstantin -- http://mail.python.org/mailman/listinfo/python-list
