我不使用setting.py来标识我的neo4j数据库。我为neo4j调用了一些函数，它们加载或查询数据库。数据库是整个python代码中使用的一个变量，因此可以轻松地对其进行更改并传播到所有下游代码。
以下是几个功能：

from neo4j import GraphDatabase
from pandas import DataFrame

neo4jdriver=GraphDatabase.driver(Neo4Server, auth=(Neo4UserName,Neo4Pswd),database='neo4j')
neo4jsession = neo4jdriver.session(database='neo4j')

def CypherToPandas(Q, database):
    driver=GraphDatabase.driver(Neo4Server, auth=(Neo4UserName,Neo4Pswd),database=database )  #"neo4j"))  #AzureLib.Neo4Pswd))
    with driver.session(database=database) as cyphersession:
        rslt = cyphersession.run(Q)
        df = DataFrame(rslt.data())
        cyphersession.close()
        driver.close()
        return df

def CypherToText(Q, database):
    driver=GraphDatabase.driver(Neo4Server, auth=(Neo4UserName,Neo4Pswd),database=database )  #"neo4j"))  #AzureLib.Neo4Pswd))
    with driver.session(database=database) as cyphersession:
        rslt = cyphersession.run(Q)
        r = rslt.data()
        cyphersession.close()
        driver.close()
        return r
