Running python script before user login

I am trying to execute this script before login:
date > /home/mahmood/dateatboot.txt
echo "In local file"
/usr/bin/python2.6 /home/mahmood/
echo "python script finished"
after restart, dateatboot.txt was created shows that the script was executed.
In the python file, I have this:
 import smtplib, commands, os, datetime
# find IP address and write to file
print 'I am in python file'
f = open('.ip.txt', 'w')
f.write( commands.getoutput("ifconfig").split("\n")[1].split()[1][5:])
After boot there is no .ip.txt file.

The first step would be to make sure your init script is actually running. Add 
some simple command that you know will not fail, and where you can see easily 
that it worked. Say, you could use


date > /home/[USER]/Desktop/created_during_boot.txt

as an init script. Then you could see that, if the file was created on your 
desktop, that the script is running at all. When you know that, THEN you can 
start to worry about Python

(I think Ubuntu probably doesn't bring up the network before NetworkManager 
does this after login. So you might just not be able to send e-mail before 
login. You can check this by saving the output of /sbin/ifconfig somewhere)
