Preventing SIGQUIT from terminating interactive python

Question

The keystroke Ctrl + \ causes python and ipython to core dump and quit immediately. How can I prevent this? I don't want to disable the key or remap the keyboard.

I have recently moved to a UK keyboard and the backslash/pipe key, which I'm used to having above the Enter key, is now located in between the left shift and the Z key. I find I'm bumping the keyboard shortcut for SIGQUIT pretty frequently and losing all my variables from the interactive interpreter.

It seems that you are on a *nix platform. Ctrl\ generates SIGQUIT, so this isn't really as much about Python.

If you want to disable the key combination you could use stty before starting Python:

stty quit undef

Alternatively, use the following to run Python:

stty quit undef; python; stty quit ^\\

which would disable the key mapping before executing python and set it back later.
