Solve the following python programming problem given the following code:
def test_node_instances2(self) : 
    dsl_path = resource ('dsl/node_instances.yaml') 
    blueprint_id1 = 'blueprint-{0}'.format (str (uuid.uuid4 ())) 
    blueprint_id2 = 'blueprint-{0}'.format (str (uuid.uuid4 ())) 
    deployment_id1 = 'deployment-{0}'.format (str (uuid.uuid4 ())) 
    deployment_id2 = 'deployment-{0}'.format (str (uuid.uuid4 ())) 
    self._create_basic_deployment (dsl_path, blueprint_id1, deployment_id1) 
    self._create_basic_deployment (dsl_path, blueprint_id2, deployment_id2) 
    all_instances = self.client.node_instances.list () 
    dep1_instances = self.client.node_instances.list (deployment_id1) 
    dep2_instances = self.client.node_instances.list (deployment_id2) 
    dep1_n1_instances = self.client.node_instances.list (deployment_id1, 'node1') 
    dep1_n2_instances = self.client.node_instances.list (deployment_id1, 'node2') 
    dep2_n1_instances = self.client.node_instances.list (deployment_id2, 'node1') 
    dep2_n2_instances = self.client.node_instances.list (deployment_id2, 'node2') 
    self.assertEqual (8, len (all_instances)) 
    def assert_dep(expected_len, dep, instances) : 
        self.assertEqual (expected_len, len (instances)) 
        for instance in instances : 
            self.assertEqual (instance.deployment_id, dep) 
assert_dep (4, deployment_id1, dep1_instances) 
    assert_dep (4, deployment_id2, blueprint_id2) 
    def assert_dep_and_node(expected_len, dep, node_id, instances) : 
        self.assertEqual (expected_len, len (instances)) 
        for instance in instances : 
            self.assertEqual (instance.deployment_id, dep) 
            self.assertEqual (instance.node_id, node_id) 
assert_dep_and_node (2, deployment_id1, 'node1', dep1_n1_instances) 
    assert_dep_and_node (2, deployment_id1, 'node2', dep1_n2_instances) 
    assert_dep_and_node (2, deployment_id2, 'node1', dep2_n1_instances) 
    assert_dep_and_node (2, deployment_id2, 'node2', dep2_n2_instances) 

    
    

    Fix the buggy line: assert_dep (4, deployment_id2, blueprint_id2)
assistant
#Here is Python program to fix the buggy line: assert_dep (4, deployment_id2, blueprint_id2)
.

assert_dep (4, deployment_id2, dep2_instances)
