Running External Commands + Seeing when they are Finished

[Tommy B]

I'm currently working on a script that I will run when I leave my
computer on at night. It runs external commands like Ad-Aware, Spybot,
AVG, Avast, and the like. The problem is, I want to know how to make it
so that one command starts only after the last one finishes. When I run
them, they end up running all at once! Can someone please tell me if
this is possible? Judging from what I've seen in Python's versitility,
I bet it can...

from os import *

for cmd in ['adaware', 'spybot']:
system(cmd)

The problem is with that (which is what I'm doing already) is that one
app is in a window and one app is on the command line. Thus, you end up
with both apps running at the same time. Are there any modules that
have functions for checking when windows are opened or closed?

Hello Tommy,

Use the subprocess module
(http://docs.python.org/lib/module-subprocess.html).

for app in MY_APPLICATION_LIST:
pipe = Popen(app)
pipe.wait()

It works! Gasp!
