#50815 — Need help with network script

Hi everyone. I am starting to learn python and I decided to start with what I though was a simple script but I guess now. All I want to do is return what current network location I am using on my mac. Every time I run it, it gives me back a 0. I don't know what I am doing wrong so here is my code. I really hope some one can help me. This script is unique to MACS btw.

import sys
import subprocess

loc = "scselect"
srn = "scselect SRN"
home = "scselect HOME"

a = subprocess.call(loc, shell=True, stdout=subprocess.PIPE)
b = subprocess.call(srn, shell=True, stdout=subprocess.PIPE)
c = subprocess.call(home, shell=True, stdout=subprocess.PIPE)

print "\n##### NETWORK SELECTION #####"
print "\nYour current location is set to \n%s" (a)

Your last line here looks wrong. Is this really the code you're using?
This code will crash with a TypeError, because you're trying to call a
string.

Copy and paste your actual code, don't re-type it :)

This is as far as I have gotten. THis is all my code and it has been copied and pasted. Thats why I am posting here. I know that the code can be better. Once I learn more it wont look like crap.

My point is that that can't be the code that always outputs "0",
because the code above would not output 0, it would terminate with
TypeError.

By the way, if you're going to use Google Groups, please read this:

In addition to reposting using copy/paste, please specify the Python 
version.  There were differences between 2.6 and 2.7.

Short answer is that subprocess.call() returns an integral returncode. 
So zero tells you that shelling to the subprocess succeeded.

Perhaps you'd like to use  subprocess.check_output() instead of 
subprocess.call().

I will try that. I am using Python 2.7
