[FIXED] How to stop execution of script, except without exiting interactive session

Issue

I like to paste hunks of code into an ipython window during development and debug. I also have a situation where I want to stop execution if a condition happens:

if condition:
  <stop running>

Solutions like sys.exit() appear to exit all the way out of ipython back to a terminal prompt. Is there another way? At the moment I do this:

if condition:
  fjklsd;

Which gives an error and returns to the ipython prompt, but is pretty ugly too.

Solution

You can raise this exception raise KeyboardInterrupt
