Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Python Interpreter Core Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Wolf Rogner (wrogner) Assigned to: Nobody/Anonymous (nobody) Summary: Destructor behavior faulty Initial Comment: I tried example 11.4. from bytesofpython (by C.H. Swaroop). Example works fine. Added a new Person instance 'wolf' -> Program terminated with: Exception exceptions.AttributeError: "'NoneType' object has no attribute 'population'" in <bound method Person.__del__ of <__main__.Person instance at 0xb7d48d6c>> ignored added print list(globals()) -> ['kalam', '__builtins__', '__file__', 'DBGPHideChildren', 'swaroop', 'Person', 'wolf', '__name__', '__doc__'] changed wolf to aaa: print list(globals()) -> ['aaa', 'kalam', '__builtins__', '__file__', 'DBGPHideChildren', 'swaroop', 'Person', '__name__', '__doc__'] Please note the position of 'aaa' at the beginning of the list, before 'Person'. With 'wolf' being after 'Person'. If the destructing code removes items in this order, no wonder I get an error. Person should not get deleted if refcount is still > 0.
