Do you mean something like the standard library ‘weakref’ module <URL:https://docs.python.org/3/library/weakref.html>? The weakref module allows the Python programmer to create weak references to objects. […] A weak reference to an object is not enough to keep the object alive: when the only remaining references to a referent are weak references, garbage collection is free to destroy the referent and reuse its memory for something else. However, until the object is actually destroyed the weak reference may return the object even if there are no strong references to it. -- \ “The cost of education is trivial compared to the cost of | `\ ignorance.” —Thomas Jefferson | _o__) | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list
