设计phython用Neo4j 图数据库显示自黑客帝国这部电影的任务关系。 1、在图 1 所示关系中，实现如下查询：谁是 Neo 的朋友？Neo 朋友的朋友？谁在恋爱？

在Python中使用Neo4j图数据库来表示《黑客帝国》电影中的任务关系，首先需要创建节点（Nodes）代表人物角色，如Neo、Morpheus、Trinity等，并创建关系（Relationships）表示他们之间的友谊、爱情或其他关联。假设我们已经有一张`Person`表作为节点，以及一张`Friendship`表和`Lovers`表作为关系。

以下是创建基本数据结构的伪代码：

from neo4j import GraphDatabase

# 创建连接到Neo4j数据库
driver = GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "password"))

def create_movie_data(tx):
    # 添加角色节点
    with tx.session() as session:
        session.run(
            """
            CREATE (:Person {name: 'Neo', role: 'Protagonist'}),
            (:Person {name: 'Morpheus', role: 'Guide'}),
            (:Person {name: 'Trinity', role: 'Warrior'})
            """
        )

    # 添加友谊关系
    with tx.session() as session:
        session.run(
            """
            MATCH (a:Person), (b:Person)
            WHERE a.name IN ['Neo', 'Morpheus'] AND b.name IN ['Morpheus', 'Trinity']
            CREATE (a)-[:FRIEND]->(b)
            """
        )

    # 添加恋爱关系
    with tx.session() as session:
        session.run(
            """
            MATCH (a:Person {name: 'Neo'}), (b:Person {name: 'Trinity'})
            CREATE (a)-[:LOVER]->(b)
            """
        )

# 执行上述操作
with driver.session() as session:
    session.write_transaction(create_movie_data)

# 实现查询
def get_friends_and_lovers(tx, person_name):
    with tx.session() as session:
        # 查询Neo的朋友
        friends_query = """
        MATCH (person:Person {name: $person_name})-[:FRIEND*]-(friend)
        RETURN friend.name AS friend_name
        """
        friends_results = session.run(friends_query, person_name=person_name)

        # 查询Neo的朋友的朋友
        friends_of_friends_query = """
        MATCH (person:Person {name: $person_name})-[:FRIEND*]->(friend_of_friend)
        RETURN friend_of_friend.name AS friend_of_friend_name
        """
        friends_of_friends_results = session.run(friends_of_friends_query, person_name=person_name)

        # 查询恋爱关系
        lovers_query = """
        MATCH (person:Person {name: $person_name})-[:LOVER]->(lover)
        RETURN lover.name AS lover_name
        """
        lovers_results = session.run(lovers_query, person_name=person_name)

        return {
            "friends": [record["friend_name"] for record in friends_results],
            "friends_of_friends": [record["friend_of_friend_name"] for record in friends_of_friends_results],
            "lovers": [record["lover_name"] for record in lovers_results]
        }

# 查询Neo的相关信息
neo_friends_data = get_friends_and_lovers(session, "Neo")
