If the output is going to a terminal window, it's not being sent to the right place.  I am not sure what kind of external Python script you are trying to use, but it sounds like it is using "print" and expecting the results to end up on a web page.  Generally speaking, this isn't how dynamic resources in Twisted Web work - you need to write something to the request object for it to end up in the browser.

Hope this helps,
