# python连接orcale数据库，oracle需要本地的客户端支撑；

from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, Integer, String, DateTime, Boolean,Float


class OracleDB(object):
    Base = declarative_base()
    def __init__(self,user='xxx',password='xxx',dabatase='xxx',serverip='10.10.10.10',port='1000'):
        user = user #'root'  
        password = password 
        database = dabatase  
        serverip = serverip 
        dns = cx_Oracle.makedsn(serverip, port, service_name=dabatase)
        self.engine = create_engine("oracle://"+user+":"+password+"@" + dns, encoding='utf-8', echo=True)
        # Session = sessionmaker(bind=self.engine)
        # self.session = Session()
    def getEngine(self):
        return self.engine

解决：

安装对应的oracle版本的client：

执行SQL查询获取oracle版本信息：

SQL> SELECT * FROM v$version;
BANNER
BANNER_FULL
BANNER_LEGACY CON_ID

Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production Version 19.8.0.0.0

我们就去下载19c对应的client文件：

可以从百度云或者csdn下载；

或者从orcale官网下载，不过注意oracle官网下载需要注册；
