Why don’t we use mod_python in a shared (cPanel) environment?

An Apache module for embedding the Python enterpreter within the Apache server, like mod_php which is the most common way of deploying PHP on a web server. Mod_python is more powerful in the way that it gives more access to Apache internals so you can do more advanced stuff. But this is a problem in
a shared environment because it’s possible to do things to Apache that will affect other websites using the same Apache instance.

Apache modules run as the user name “Nobody” which means, if a file was writable, any client on the server using mod_python would be able to overwrite other clients files which is a security risk on a shared
environment.
