How to stop Google Colab runtime without it automaticly restarting

Question

I want to stop a Google Colab Runtime with code when the thing I want to do has ended, so I though of putting a line of at the end that would stop it from running. I have tried these, but none work. They all restart after stopping or then just give and error.

I got them from here:

• Is there a function in google.colab module to close the runtime
• https://newbedev.com/google-colab-how-to-restart-runtime-using-python-code-or-command-line-interface

---

import os
os.kill(os.getpid(), 9)

---

import sys
sys.exit()

---

exit()

---

quit()

---

!kill -9 -1

---

There is a shortcut for ending all runtimes, (It's undefined by default by I added it as Ctrl + Shift + K) and maybe I could write a program that would virtually typed these keys. But it makes a popup before ending the Runtime and I may not be there to accept the popup.

How do I do this? Thanks!
