                            "tagline": "Pain heals, Chicks dig scars... Glory lasts forever",
                            "title": "The Replacements",

                        }
                    }
                }
            ],
            "length": 1
        }
    }
]

In order to export json,I use the code like this:

class JsonExtactor(object):
    def __init__(self):
        super(JsonExtactor,self).__init__()
        self.graph = Graph(
            "http://localhost:7474",
            auth=('neo4j','neo4j'))
    def run(self):
        try:
            return(self.graph.run("MATCH p=()-[r:ACTED_IN]->() RETURN p LIMIT 2", {}).data())
        except Exception as e:
            print(e)
            return None
JsonExtactor().run()

But it only returns a list like this:

[{'p': Path(Node('Person', born=1964, name='Keanu Reeves'), ACTED_IN(Node('Person', born=1964, name='Keanu Reeves'), Node('Movie', released=2003, title="Something's Gotta Give")))}, {'p': Path(Node('Person', born=1964, name='Keanu Reeves'), ACTED_IN(Node('Person', born=1964, name='Keanu Reeves'), Node('Movie', released=2000, tagline='Pain heals, Chicks dig scars... Glory lasts forever', title='The Replacements')))}]

How to response the json format which is like above json structure ?

Please help me

Thanks
