How to exit from a Python code?

Hello,

If your code is written in a GHPython node, is there a way to exit from the code in the middle of the code?
You can exist from a function by “return”.
You can exit from a for loop by “break”
Buf when your code is at the top level, how to exit?

Try
exit()

Or put all your code in a main() function and return to exit : this is good practice in Python

if __name__ == ‘__main__’:
    main()

Thank you both.
Seems like exit() does not work for GHPython node. I’ll try making a main() function.

You can also do it if you use the exit() function in your code. More ideally, you can do sys.exit() . sys.exit() which might terminate Python even if you are running things in parallel through the multiprocessing package.

Note: In order to use the sys.exit() , you must import it: import sys
