Except that it doesn't. From the docs: "It is not guaranteed that __del__() methods are called for objects that still exist when the interpreter exits." https://docs.python.org/3/reference/datamodel.html#object.__del__ That limitation of CPython is much reduced now compared to older versions, but there are still circumstances where the __del__ method cannot be called. -- Steve -- https://mail.python.org/mailman/listinfo/python-list
