Ryan Heisler added the comment: Perfect, thanks for your quick response. I was passing a bound method of obj as the func to `weakref.finalize(obj, func, /, *args, **kwargs)`. It slipped my mind that an instance variable like self.name and a bound method like self.clean_up, though they both

[issue42945] weakref.finalize documentation contradicts itself RE: finalizer callback or args referencing object

Tim Peters added the comment: Not a problem. Arguments to a function are evaluated before the function is invoked. So in self._finalizer = weakref.finalize(self, shutil.rmtree, self.name) self.name is evaluated before weakref.finalize is called(). `self.name` _extracts_ the `.name`
