Thanks for the tips everyone, although it turns out this is not a python
problem at all. After several tests with mpg123 both direct on the cli, and
wrapped in an os.system() call, I see it is _always_ returning 0 exit status
whether I interrupt it or not. I went to the mpg123 website to see if

That's also kind of what I expected.
However, I quickly tried:
import os
while 1:
y = os.system("sleep 1")
z = (y >> 8) & 0xFF
print z
I never get anything in return but 0, hitting c-C or not.
I have uset the above code to get exit code returns in the past though.
Would there be any

You can tell by the exit code from system() whether the subprocess
exited due to a signal. Consider this code:
import os
while 1:
print os.system("sleep 1")
unless you happen to hit ctrl-c at the right time, you'll see it print
"2" (and "0" when the sleep finishes). The exit code

Hello all.
I have a python script here which is just a wrapper for 2 or more system
commands. I would estimate the program spends at least 95.5% of 'real' time
running the system commands.
I want to trap the [crtl-c] key combo and exit (somewhat) gracefully if the
user decides to abort the pro
