This code makes no sense to me. What do you expect it to do?

    def get_or_create_node_id(self,node_name,c,cur,nodes):
        if node_name in nodes:
            print ("%s found in dict, has id %s" % ( node_name, nodes[node_name] ))
            return int(nodes[node_name])
        else:
            print("creating new node entry ..")
            sql = "INSERT INTO nodes VALUES (DEFAULT, '%s')" % (node_name)
            cur.execute(sql)
            c.commit()
            return self.get_or_create_node_id(node_name)

it looks in the database of the "node" is already there, if yes it returns the id of the node (db id), if no it creates the node in the db.
