exception - exit failed script run (python) -

After successfully completing a task, I have seen many questions about coming out of a script, but for doing so Is there a way to have a script that has failed? I am writing a test script which only checks that a camera is working correctly if the first test fails, it is possible that the following tests will fail; That's why I have the first time trying to get an exit and to provide the output to the screen, I know there was an error.

I hope this is enough information; Let me know that I need more information to help.

Are you looking for a function?

  Import if 1 & lt; 0: Print & gt; & Gt; Sys.stderr, "Something is seriously wrong." Sys.exit (1)  

exit () is the return code (optional), the script will return to the shell. Usually indicates an error compared to 0.
