You should run your external programs from Python using an External Method.
However, you want to think about security - you don't want to let a random
client be able to execute just anything. I recommend some configuration
code that checks the request (and maybe the user) and only allows certain
specified programs to be run. Requests for anything else would be
rejected - in fact, they would not even be understood.
You also have to work out how to handle it in case the external program
fails or hangs.
