How to abort python script from IPython (console)

Question

I'm using embed() from IPython (console), to interact with my script. Whenever I press CTRL+D it exits the interactive mode and proceeds to the next commends following the embed() call.

How do I abort the complete python script avoiding it from going to further commands after embed() from the interactive python?

What I have tried:

CTRL+C : only cancels my current command in the IPython

CTRL+D : leaves the IPython and proceeds to the next commands in my script

Typing exit() : same as CTRL+D

Here is a sample script:

#!/usr/bin/env python

from IPython import embed

print 'hello world'
embed()
print 'I dont want to reach here if I decide to quit from the IPython terminal!'

Are you speaking about iPython notebook? Or just the iPython console ? — User2342342351

@user312016 I simply make my script executable and type ./script.py. I use #!/usr/bin/env python in its header. — rph

One option is to nuke the process ID from the IPython session:

$ python test_embed.py
hello world
Python 2.7.10 |Anaconda 2.3.0 (x86_64)| (default, May 28 2015, 17:04:42)
Type "copyright", "credits" or "license" for more information.

object?   -> Details about 'object', use 'object??' for extra details.

In [1]: import os

In [2]: os.kill(os.getpid(), 9)
Killed: 9

EDIT: Looks like sending SIGQUIT with Ctrl-\ will also terminate the script entirely.

This definitely works, but I wonder if there is any easier shortcut.

`Ctrl-` is what I was looking for! Thanks perfect.
