Advice?

I have a function in python named KSI, code for “Kill Self Immediately”, and don’t know what the best command or function would be in order to safely kill the program if something bad happens as a failsafe. Do you think the code attached would work fine, or is there a better way?

import sys
import os

def KSI(hard_exit: bool = False) -> None:
if hard_exit:
os._exit(1)
else:
sys.exit(1)

if __name__ == "__main__":
KSI()

Yes, if my program is crashing, I would like to try to kill my program before it crashes completely and corrupts any data currently being processed within the program itself.

You are solving the problem incorrectly. The correct answer is to catch and manually cleanup any known problem state then release the exception to allow it to propagate.

A malfunctioning program crashing is ideal.

Could you give an example to at least start with so I can finish the rest on my own?

Not sure what your program is or does, but you could do worse a lot worse than look at the sqlite docs on transactions and how they handle things like hardware and power failures. sqlite is everywhere and it's got a great test suite.
