February 21, 2022 - To exit a Python program early, call sys.exit with 0 for success, 1 for error, or a string (to print an error message while exiting).

If another type of object is passed, None is equivalent to passing zero, and any other object is printed to stderr and results in an exit code of 1. In particular, sys.exit("some error message") is a quick way to exit a program when an error occurs.

Calling sys.exit(0) raises a SystemExit exception and terminates the interpreter without printing a traceback.

October 10, 2021 - More obscurely, we can pass SystemExit any object, in which case Python will print the str() of that object to stderr and return an exit code of 1:

April 21, 2021 - The number passed to sys.exit is the exit code. In Unix, an exit code of 1 means something went wrong. An exit code of 0 means it was successful. On the command line, you can see the exit code of the last command using echo $?. >>> python successful_script.py >>> echo $? 0 >>> python ...

June 5, 2023 - if error_occurred: sys.exit(1) # Terminate the program with status code 1 indicating an error

This function prints numbers from 1 to 20 but exits gracefully when it reaches 10, returning a status code of 0 (indicating successful completion). While sys.exit() ensures proper handling, os._exit() is a lower-level function that forces immediate termination without executing cleanups. Let’s examine it next. When a Python program needs to terminate instantly, bypassing all cleanup routines and exception handling, os._exit() is the go-to command.

July 27, 2023 - 2. Job Terminate with sys.exit(1) - when the job criteria meet some condition, then we do terminate the job with sys.exit(1), which basically terminates the job by marking the job as failed. the above criteria work as expected in any Python environment but not in Databricks.

March 22, 2020 - Should be 141 instead of 1. Convention is that when a program dies because of a signal, the exit code should be 128 + the signal number, in this case 13. So, 128 + 13 = 141 · Here are some examples:

November 11, 2022 - Hi Team, In my project I used try except block , if exception occured I used sys.exit() I saw exit() in someones code , when to use sys.exit and exit() if not Path.exists(source_path): print(f'Source path: {source_path} does not exists'...

August 9, 2023 - We are successfully launching Rhino 7 with command line parameters to run a script. For testing, the script just waits a few seconds and then exits with the sys.exit() command. Except that it always displays a popup window so that a user has to press a button.

A slightly more technical example: You are from a Shell and want to run a Python script, but you need to know if everything went well. One way to know if everything was executed correctly is to see some value that your script returns. Not only can you go out with sys.exit (), you can also go out with a custom value like sys.exit (1) or sys.exit (999) and use that value returned by your program to do one or another action from your shell.

May 22, 2025 - The sys.exit() function stops the entire program. If provided, the argument (e.g., "Goodbye!") is displayed to the console, or passed to the parent process when used in automation pipelines.

In Python, you can check the exit code of a script using the `sys.exit()` function provided by the `sys` module. By default, if your script runs without any issues, it will have an exit code of 0 (zero), which indicates success .

September 22, 2024 - import sys import argparse def main(): parser = argparse.ArgumentParser(description="Sample CLI program") parser.add_argument("--name", help="Your name") args = parser.parse_args() if args.name: print(f"Hello, {args.name}!") else: print("Error: Please provide your name using --name") sys.exit(1) sys.exit(0) if __name__ == "__main__": main() ... import sys import signal def signal_handler(sig, frame): print("\nCtrl+C pressed. Exiting gracefully...") sys.exit(0) signal.signal(signal.SIGINT, signal_handler) print("Running... Press Ctrl+C to exit.") while True: pass # Simulate long-running process · Whether you're developing scripts, command-line tools, or complex applications, mastering the exit() function will enhance your Python programming skills and improve the overall quality of your software.
