python mod_wsgi Hello World application

Hello, I'm having a problem getting even a simple 'hello world' WSGI-based python app to run on Webfaction. Here are the steps that I did: 1. I created a new domain (hydrodata.eu). I checked that the nameservers are pointed to webfaction.com 2. I created a new website (hydrodata) and I linked it to the domain in webfaction's control panel. 3. I created a new application: myapp "WSGI application" and I linked it to the new hydrodata website.

Now when I log in to my account via SSH I have the following file structure: $HOME/webapps/myapp/apache2 $HOME/webapps/myapp/htdocs

Now I create an executable python file $HOME/webapps/myapp/hello.py

In the file I put the following code (I used example from Wikipedia WSGI article):

    def application(environ, start_response):
        start_response('200 OK', [('Content-Type', 'text/plain')])
        yield 'Hello Worldn'

Now when I go in my browser to http://hydrodata.eu/hello.py I get a "404" error message "Not Found".

Any ideas what I'm doing wrong? Do I need to edit anything in the $HOME/webapps/myapp/apache2/conf/httpd.conf file?
