python - IPython Notebook - early exit from cell

Question

I'd like to programmatically exit a cell early in IPython Notebook. exit(0), however, kills the kernel.

Whats the proper way to do this? I'd prefer not to split the cell or manually halt execution.

Answer 1

Slightly more "proper" options:

This will get you out of all but the worst try/except blocks.

raise KeyboardInterrupt

A little cleaner version of yours:

assert(False)

or simply:

raise

if you want to save a couple keystrokes.
