And here's a version that doesn't lose updates to the finalizer attributes:

http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/519635 It replaces enablefinalizer() with a class attribute finalattrs. >From finalize, all class attributes and methods are accessible, as are any instance attributes specified by finalattrs. Guido's BufferedWriter example looks like:: class BufferedWriter(Finalized): finalattrs = 'buffer', 'raw' ... def flush(self): self.raw.write(self.buffer) self.buffer = b"" def finalize(self): self.flush()

But can I subclass it and in the subclass override (extend) flush()? E.g.

class MyWriter(BufferedWriter): def flush(self): super(MyWriter, self).flush() # Or super.flush() once PEP xxx is accepted print("Feel free to unplug the disk now")
