To stop code execution in Python you first need to import the sys object. After this you can then call the exit() method to stop the program from running. It is the most reliable, cross-platform way of stopping code execution.
A process can be killed by calling the Process. kill() function.
terminate() function will terminate foo function. p. join() is used to continue execution of main thread. If you run the above script, it will run for 10 seconds and terminate after that.
Python sys module contains an in-built function to exit the program and come out of the execution process — sys. exit() function. The sys. exit() function can be used at any point of time without having to worry about the corruption in the code.
To exit a script you can use,
import sys
sys.exit()
You can also provide an exit status value, usually an integer.
import sys
sys.exit(0)
Exits with zero, which is generally interpreted as success. Non-zero codes are usually treated as errors. The default is to exit with zero.
import sys
sys.exit("aa! errors!")
Prints "aa! errors!" and exits with a status code of 1.
There is also an _exit() function in the os module. The sys.exit() function raises a SystemExit exception to exit the program, so try statements and cleanup code can execute. The os._exit() version doesn't do this. It just ends the program without doing any cleanup or flushing output buffers, so it shouldn't normally be used.
The Python docs indicate that os._exit() is the normal way to end a child process created with a call to os.fork(), so it does have a use in certain circumstances.
You could put the body of your script into a function and then you could return from that function.
def main():
done = True
if done:
return
# quit/stop/exit
else:
# do other stuff
if __name__ == "__main__":
#Run as main program
main()
import sys
sys.exit()
You can either use:
import sys
sys.exit(...)
or:
raise SystemExit(...)
The optional parameter can be an exit code or an error message. Both methods are identical. I used to prefer sys.exit, but I've lately switched to raising SystemExit, because it seems to stand out better among the rest of the code (due to the raise keyword).
Try
sys.exit("message")
It is like the perl
die("message")
if this is what you are looking for. It terminates the execution of the script even it is called from an imported module / def /function
exit() should do the trick
exit() should do it.
