Well, the version of python-mode i've go t'would still put that as 

    self.data[x][y].variable = (
        self.long_function_name(
        lots,
        of,
        arguments 
        )
        )

Which is better than i thought it would be:

    self.data[x][y].variable = (
                                self.long_function_name(
                                                        lots,
                                                        of,
                                                        arguments 
                                                        )
                               )

But I still need to change it sometime =)
