python调用oracle

访问 Oracle Instant Client 下载页面：Oracle Instant Client Downloads，下载以下文件：Basic Package: 包含基本的库，解压下载的文件到一个目录oracle-instantclient

在终端中运行以下命令(加入path也可以)：
export DYLD_LIBRARY_PATH=/Users///oracle-instantclient

终端运行pip install cx_Oracle

import cx_Oracle
connection = None
try:
    connection = cx_Oracle.connect(
        user='ISPDC',
        password='CONTI',
        dsn='127.0.0.1:1521/DBSABS06'
    )
    print("Connection successful")
except cx_Oracle.DatabaseError as e:
    print("Database connection error:", e)
finally:
    if connection:
        connection.close()

ORA-24454: client host name is not set
终端输入hostname，获取返回结果，然后编辑hosts文件，输入"127.0.0.1"对应hostname返回的结果，就可以了
