No, an object that holds reference to other objects is something like a list, tuple, dict. e.g. if you had: a = [] b = [a] a.append(b) you've got two lists, and each one has a reference to the other one. These exist independent of the variables - you could del b and it would still exist in a[0]. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
