No. The function below is called on an event within a wxpython app.

The following line is what I mean by calling a command line from within the app
using subprocess.

self.espeak = subprocess.Popen(['espeak', word],stdout =
subprocess.PIPE).communicate()[0]

To functions in libraries external to python.

Basically the below.

So it's basically just installing a sandbox version of python?

I was just saying the module I was using for the apps framework

No significance, it was just an example to illustrate my question.
Which ultimately is, if I have a standalone application, that doesn't
come from a command line terminal launching(which I haven't gotten to
yet), is using the command line calls going through subprocess going
to be called without the terminal, or will it open a terminal
automatically to make those calls?

Or will all of my python apps need to have a command line terminal
open to launch them. I haven't went all the way through the distutils
docs, so this might be answered with further reading, but I wanted to
know the answer before I did several basic apps like this. Although
I'll probably still do them for my own personal usage.

I don't exactly ask the most well layed out questions, but I'm working on it.
