how can we capture exit code of bash script while running the bash script in python

Question

I am executing a bash script using subprocess module.

subprocess.call(['temp.sh'])

As per python if the temp.sh file is present it calls the script and it doesn't worry about the success or failure of temp.sh. I want to capture the exit code of temp.sh in order to proceed further with rest of my python script.

And don't used .sh at end of files names. It is bad practice, consider what would have to change if you re-wrote the script in python. — ctrl-alt-delor, Sep 16 '20 at 13:07

The subprocess.call function returns a returncode object, which is an int. It will be the value of the exit code of the subprocess process.

>>> foo = subprocess.call(['/usr/bin/true'])
>>> foo
0
>>> foo = subprocess.call(['/usr/bin/false'])
>>> foo
1
