Python os._exit () sys.exit ()

Os._exit () will terminate the Python program directly, and all subsequent code will not continue to execute.

Sys.exit () throws an exception: Systemexit, if the exception is not captured, the Python interpreter exits. If there is code to catch this exception, the code will still execute. Catching this exception can do some extra cleanup work. 0 for normal exit, other values (1-127) are not normal, can throw abnormal events for capture.
