Handling exit code returned by python in shell script

Question

I am calling a python script from within a shell script. The python script returns error codes in case of failures.

How do I handle these error codes in shell scrip

Answer 1

Please use logic below to process script execution result:

python myPythonScript.py
# $? =  is the exit status of the most recently-executed command; by convention, 0 means success and anything else indicates failure. 
if [ $? -eq 0 ]
then
  echo "Successfully executed script"
else
  # Redirect stdout from echo command to stderr.
  echo "Script exited with error." >&2
