folks, what's wrong with this?

Hi All:

I am just a beginner in python. Can anyone please tell me what is
wrong with this piece of code?

import copy
class BaseDummyObject(object):

    def __init__(self):
        pass

    def __getattr__(self, item):
        try:
            return self.__dict__.__getitem__(item)
        except KeyError:
            print "Attribute Error: attr %s of class %s non-existent!"
%(item,
 
self.__class__.__name__)
class DummyObject(BaseDummyObject):
        pass


def main():
    bar = 3
    obj = DummyObject()
    obj.foo = bar
    obj.me = obj

    newobj = copy.deepcopy(obj)


if __name__ == "__main__":
    main()

So when I do this, I get:

Attribute Error: attr __deepcopy__ of class DummyObject non-existent!
Attribute Error: attr __getnewargs__ of class DummyObject non-
existent!
Traceback (most recent call last):
  File "C:\Workspace\QA3.0\Python_Lib\Mobidia\RemoteManager
\test_code.py", line 39, in <module>
    main()
  File "C:\Workspace\QA3.0\Python_Lib\Mobidia\RemoteManager
\test_code.py", line 30, in main
    newobj = copy.deepcopy(obj)
  File "C:\Python26\lib\copy.py", line 181, in deepcopy
    rv = reductor(2)
TypeError: 'NoneType' object is not callable

Any help will be really appreciated.
