How to stop a Python script without error messages on the shell?

Question

I want to stop a Python script on seeing an error message.
I dont want any error message on shell like exit().
How to do it ???

Could you please provide some code or at least a better description of what you are trying to achieve? — hyperboreean

Since sys.exit(0) does not produce an error message, I'll assume you're not talking about Python. — S.Lott

@S. Lott I think he means "I don't want any error message on shell, but a clean exit as sys.exit() does". — Gonzalo Quero

When you send CTRL+C to a Python script, it raises the KeyboardInterrupt exception, so you can do something like

try:
    ... Work goes here ...
except KeyboardInterrupt:
    sys.exit(0)

I think he actually meant to ask how to suppress the error message/traceback at ANY error, so the 3rd line would be except: instead of except KeyboardInterrupt:

@Rod: I would certainly hope not, as that would make the program impossible to debug.

@Rod: A bare except should never be used unless the error is raised again, because it hides real errors.
