I think you really want to do this:
tree = [] for i in xrange(200): n = item(str(i),i) tree.append(n) self._tree = tree
Thanks for the suggestion. Your code does about the same as my did - it also reproduces the 20000 references to objects of the item-class. And I also don't get rid of the 20000 references. I tried it! :-(
I was about to ask if your item() objects are persistent, when I read Chris McDonough's post. If you are storing al 20,000 items, no wonder you see memory uasge increasing.
Yes, the item() objects are persistent. And if I do recursive creation and deletion of the objects which contains the list with the persistent item() objects the references to the item objects are still growing. I just made the item objects not persistent, and it seems to work, so no growing references. So I wonder way the reference counter for persistent item objects is still growing by the recursive process of creation and deletion. christoph
