error rising while connecting oracle 9i

[wittempj@hotmail.com]

Check:
1. Whta is the Python version your running, with
py> import sys
py> print sys.version
2.4.2 (#2, Sep 30 2005, 21:19:01)
[GCC 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu8)]
2. Download the correct version of cx_Oracle
see http://www.cxtools.net/default.aspx?nav=cxorlb
then execute the command again - supposed your user is "myusername",
your assword is "mypassword", and your dsn is "python".

The dns should match an entry in the 'tnsnames.ora' - the location  of
this file depends on running Oracle on a Windows or Unix server.

If you need more help please post more info like:
* Oracle version (including subnumbers)
* Python version
* cx_Oracle version
* OS version
* DNS entry
* exact traceback
