You have forgotten to tell us which problem the code above revealed. > When I tried overwrite __getstate__ to below: > def __getstate__(self): > return self.__repr__() > pickle it will shows: > b'\x80...__main__...Wrapper...' <- I don't know why it shows the class name. > That makes me confused. It should not: pickling a class instance entails pickling a class reference and the instance's state. The class name is part of the class reference. -- https://mail.python.org/mailman/listinfo/python-list
