Only root can write in /var/log/ on Mac OS X...:
$ ls -ld /var/log drwxr-xr-x 60 root wheel 2040 Oct 6 17:00 /var/log Maybe consider using the syslog module in the standard library...

@nur,
import syslog of course -- see docs.python.org/library/syslog.html for all the details!

@alex thank u very much. actually what i want to achieve is that, i am writing a launchagent application for osx using python. it writes some meta info in a sqlite db from time to time. these data cannot be seen by user without root privilege. so i need to keep this db file in place where only root has access. how can i achieve that?

@nur, you can achieve that only by running as root (not recommended, but it IS the only way to do exactly what you ask: update a sqlite db which ONLY root can access).
It probably failed because /var/log has user set to root and group set to wheel. Try running your python code as root and it will probably work.

thank u. my application is a launchagent application. it runs during start up and saves some data in file time to time. data saved by the application cannot be viewed without root privilege. how can i achieve that?
You can create the log file as root and then change the owner to the user your script is run as
# touch /var/log/mylogfile # chown myuser /var/log/mylogfile where mylogfile is your logfile and myuser is the user the script will be run as
also look into logrotate
