Get exit status code from Python, e.g. 0 or 1

Question

I have a Python script which will do some actions, and depending on the result, will exit with a code 0 (all right) or 1 (not good).

I want to catch this result, store it into a variable and send it over UDP. This cannot be done inside the Python script (requirement).

So let's say my script is something like:

import sys
# Do some stuff
sys.exit(0) # or sys.exit(1)

Which I run with python script.py.

How can I get this exit status code (0 or 1)?

I try to echo $errorlevel, but it only prints a blank line. I also try to use exit(0) instead of sys.exit() (see here) and some other unsuccessful attempts.

Answer 1

Since as per your answer you are using zsh

test.py

import sys
sys.exit(12)

in your console

python test.py
RC=$?
echo "Exit code $RC"
program_to_send $RC

Answer 2

It's a script question, not a Python question, but in the Bash shell you use $? and since any command changes $?, it's usually a good idea to save a copy.

python script.py
RC=$?

echo $RC
[ $RC == 0 ] && echo Success || echo Failed
# Replace above lines by whatever you need to send $RC via UDP ...
