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...

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.

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
