Trying to set a cookie within a python script

[Νίκος]

If you just click in my web page to see the script run in action due
to the cgitb module i use it will provide you both the source code
that the error appears and the error as well.

All you have to do is click here: http://www.webville.gr/cgi-bin/koukos.py

As for the encoding why when i print greek characters they dont appear
correctly in chrome in runtime?
