Python3.5在Windows 7下連接ORACLE數據庫

1、首先需要安裝好oracle數據庫，本機適用plsql連接數據庫正常，記錄下數據庫名稱

2、安裝cx_oracle模塊

pip install cx_Oracle

3、python中引入模塊

import cx_Oracle as cx

4、測試

conn = cx.connect('sys/password@localhost/orcl')   
cursor = conn.cursor () 
cursor.execute ("select * from dual") 
row = cursor.fetchone () 
print (row)   
cursor.close () 
conn.close ()
