本文主要是介绍python3.3.5+oracle+windows，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
安装文件windows，安装了有些版本不兼容，就安装了python3.3.5和cx_Oracle-5.1.3-11g.win32-py3.3.exe 以及oracle监听器
把oci.dll ， oraocci11.dll，oraociei11.dll放在安装目录 C:\Python33\Lib\site-packages下 如图
编写代码测试：
'''
连接数据库 oracle
'''
import cx_Oracle as db
#
username = "xx_ss"
passwd = "xx"
host = "192.168.176.122"
port = "1521"
sid = "orcl"
dsn = db.makedsn(host, port, sid);
con=db.connect (username,passwd,dsn)
cursor = con.cursor()
sql='select * from T_USER'
cursor.execute (sql)
result = cursor.fetchall()
print("Total: " + str(cursor.rowcount))for row in result:print (row)
cursor.close()
con.close()
C:\Python33\python.exe C:/Users/xiefg/PycharmProjects/test/test.py
Total: 10
