Solve the following python programming problem given the following code:
def create_fake_clusters(self) : 
    self.now = datetime.utcnow ().replace (microsecond = 0) 
    self.add_mock_s3_data ({ 
        'my_bucket' : { 
            
}, 
}) 
    def ago(**kwargs) : 
        if any (((v is None) for v in kwargs.values ())) : 
            return None 
return to_iso8601 ((self.now - timedelta (** kwargs))) 
def step(jar = '/home/hadoop/contrib/streaming/hadoop-streaming.jar', args = self._DEFAULT_STEP_ARGS, state = 'COMPLETED', create_hours_ago = None, start_hours_ago = None, end_hours_ago = None, name = 'Streaming Step', action_on_failure = 'TERMINATE_CLUSTER', **kwargs) : 
        return MockEmrObject (config = MockEmrObject (actiononfailure = action_on_failure, args = [MockEmrObject (value = a) for a in args], jar = jar), status = MockEmrObject (state = state, timeline = MockEmrObject (creationdatetime = ago (hours = create_hours_ago), enddatetime = ago (hours = end_hours_ago), startdatetime = ago (hours = start_hours_ago)))) 
self.add_mock_emr_cluster (MockEmrObject (id = 'j-EMPTY', status = MockEmrObject (state = 'STARTING', timeline = MockEmrObject (creationdatetime = ago (hours = 10))))) 
    self.add_mock_emr_cluster (MockEmrObject (id = 'j-BOOTSTRAPPING', status = MockEmrObject (state = 'BOOTSTRAPPING', timeline = MockEmrObject (creationdatetime = ago (hours = 10))), _steps = [step (create_hours_ago = 10, state = 'PENDING')])) 
    self.add_mock_emr_cluster (MockEmrObject (id = 'j-CURRENTLY_RUNNING', status = MockEmrObject (state = 'RUNNING', timeline = MockEmrObject (creationdatetime = ago (hours = 4, minutes = 15), readydatetime = ago (hours = 4, minutes = 10))), _steps = [step (start_hours_ago = 4, state = 'RUNNING')])) 
    self.add_mock_emr_cluster (MockEmrObject (id = 'j-DONE', status = MockEmrObject (state = 'TERMINATED', timeline = MockEmrObject (creationdatetime = ago (hours = 10), readydatetime = ago (hours = 8), enddatetime = ago (hours = 5))), _steps = [step (start_hours_ago = 8, end_hours_ago = 6)]))
