Solve the following python programming problem given the following code:
def test_node_deletion_subtask_progress(self) : 
    supertask = Task (uuid = str (uuid.uuid4 ()), name = 'super', status = 'running') 
    self.db.add (supertask) 
    task_deletion = supertask.create_subtask ('node_deletion') 
    task_provision = supertask.create_subtask ('provision', weight = 0.4) 
    self.db.commit () 
    subtask_progress = random.randint (1, 20) 
    deletion_kwargs = { 
        'task_uuid' : task_deletion.uuid, 
        'progress' : subtask_progress, 
        'status' : 'running', 
} 
    provision_kwargs = { 
        'task_uuid' : task_provision.uuid, 
        'progress' : subtask_progress, 
        'status' : 'running', 
} 
    def progress_difference() : 
        self.receiver.provision_resp (** provision_kwargs) 
        self.db.commit () 
        self.db.refresh (task_provision) 
        self.assertEqual (task_provision.progress, subtask_progress) 
        self.db.refresh (supertask) 
        progress_before_delete_subtask = supertask.progress 
        self.receiver.remove_nodes_resp (** deletion_kwargs) 
        self.db.commit () 
        self.db.refresh (task_deletion) 
        self.assertEqual (task_deletion.progress, subtask_progress) 
        self.db.refresh (supertask) 
        progress_after_delete_subtask = supertask.progress 
        return abs ((progress_after_delete_subtask - progress_before_delete_subtask)) 
without_coeff = progress_difference () 
    task_deletion.progress = 0 
    task_deletion.weight = 0.5 
    self.db.merge (task_deletion) 
    task_provision.progress = 0 
    self.db.merge (task_provision) 
    supertask.progress = 0 
    self.db.merge (supertask) 
    self.db.commit () 
    with_coeff = progress_difference () 
    self.assertTrue (((supertask / with_coeff) < 2)) 

    
    

    Fix the buggy line: self.assertTrue (((supertask / with_coeff) < 2))

#Here is Python code to fix the buggy line: self.

self.assertTrue (((without_coeff / with_coeff) < 2))
