Question

我正在尝试使用 neo4j python驱动程序访问neo4j。我正在运行以下代码来获取事物A 的属性。我打开驱动程序并进行会话直接从neo4j的GraphDatabase获取并使用 session.run（）来执行图形查询。这些查询返回一个 BoltStatementResult 对象。我的问题是如何将该对象转换为我需要的实际结果（事物A的属性）。

    from neo4j import GraphDatabase

uri = "bolt://abc:7687"
driver = GraphDatabase.driver(uri, auth=("neo4j", "password"))

def matchQuestion(tx, intent,thing):

    result = tx.run("MATCH (e:thing) WHERE e.name = {thing}"
           "RETURN e.description", thing=thing)

    print(result)

with driver.session() as session:
    session.read_transaction(matchQuestion, "define","A")

Answer 1

result = tx.run("MATCH (e:thing) WHERE e.name = {thing}"
           "RETURN e.description AS description", thing=thing)

for line in result:
    print line["description"]

或

print result.single()

您还可以指定项目位置，例如-

print result.single()[0]

从Cypher Bot语句获取结果
