I wrote the below code

    def decorated(self, *args, **kw):
        'The    decorated    function    that    replaces    __init__()    or    __setstate__()\n\n                '
        if (not hasattr(self, '_canAddAttributes')):
            self.__dict__['_canAddAttributes'] = 1
        else:
            self._canAddAttributes += 1
        assert (self._canAddAttributes >= 1)
        count = self._canAddAttributes
        f(self, *args, **kw)
        if hasattr(self, '_canAddAttributes'):
            self._canAddAttributes -= 1
        else:
            self._canAddAttributes = (count - 1)
        assert (self._canAddAttributes >= 0)
        if (self._canAddAttributes == 0):
            del self._canAddAttributes
    decorated.__doc__ = f.__doc__
    decorated.__name__ = f.__name__
    return decorated
