Parse Python script on Apache virtual host

I have an up and running Apache server working with PHP on a Centos 6 server. Apache was installed using yum -y install httpd mod_ssl. I now wish to add Python.

I installed Python as follows:

wget http://python.org/ftp/python/3.3.5/Python-3.3.5.tar.xztar xf Python-3.3.5.tar.xzcd Python-3.3.5./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"make && make altinstall

I installed mod_python using yum install mod_python.

/etc/httpd/conf/httpd.conf includes the following line Include conf.d/*.conf, so then I know that /etc/httpd/conf.d/python.conf has been included. I made no changes to /etc/httpd/conf.d/python.conf, and the only un-commented directives are:

LoadModule python_module modules/mod_python.so<Directory "/var/www/manual/mod/mod_python"><Files *.html>                SetHandler default-handler</Files></Directory>

I then added the following VirtualHost.

<VirtualHost *:80>    ServerName example.com    DocumentRoot /var/www/python/html<Directory /var/www/python/html/>      Options Indexes FollowSymLinks MultiViews      AllowOverride None      Order allow,deny      allow from all      AddHandler mod_python .py      PythonHandler mod_python.publisher      PythonDebug On</Directory>    AddHandler mod_python .py        #DirectoryIndex index.html index.php index.py</VirtualHost>

If I access http://example.com/testphp.php, it is parsed as PHP, however, if I access http://example.com/testpython.py, it returns a 404 Not Found error. If I comment out PythonHandler mod_python.publisher, it returns the Python script un-parsed.

How do I use Python on a virtual host?

EDIT. If testpython.py consists of script print( 'xxxx' ), I get the 404 error. If it consists of the following, it returns Test successful.

def index(req):  return "Test successful";

Both produce the following notice in /var/log/httpd/error_log:

[Mon Dec 07 07:03:14 2015] [notice] mod_python (pid=16441, interpreter='example.com'): Importing module '/var/www/python/html/testpython.py'
