Solve the following python programming problem given the following code:
def _mock_lookup_configdrive_path(self, ext, rescue = False) : 
    self._pathutils.get_instance_dir = mock.MagicMock (return_value = configdrive_path.fake_instance_dir) 
    def mock_exists(* args, **kwargs) : 
        path = args [0] 
        return (True if (path [(path.rfind ('.') + 1) :] == ext) else False) 
self._pathutils.exists = mock_exists 
    configdrive_path = self._pathutils.lookup_configdrive_path (self.fake_instance_name, rescue) 
    return configdrive_path 

    
    

    Fix the buggy line: self._pathutils.get_instance_dir = mock.MagicMock (return_value = configdrive_path.fake_instance_dir)

#Here is Python program to find ('.

self._pathutils.get_instance_dir = mock.MagicMock (return_value = self.fake_instance_dir)
