[mod_python] newbie

Hello!

I want to try mod_python, but something doesn't work fine

I'm using Apache 2.0.47 (Mandrake Linux/1.6.91mdk) mod_python/3.0.1 
Python/2.2.2 in a Mandrake9.1 and my  http2.conf is:

...
LoadModule python_module                 extramodules/mod_python.so
...
<Directory /var/www/html>
  AddHandler python-program .py
  PythonHandler mptest
  PythonDebug On
</Directory>

and, of course there's a mptest.py in /var/www/html

But pointing to my mptest.py, my mozilla opens the dialog for 
downloading the file.

What's wrong?

Thanks
