Logging handler to send python logging to the jupyter log console?

[darikg]

Jupyter has a log console for viewing log messages, but my understanding is that this is just for javascript logging. Is there a way to redirect standard python logging module messages to this console? I think it'd be more convenient than printing to stdout.

Not currently, but sounds like an interesting extension someone could write. It would have to somehow integrate on the kernel side with the logging system.

It might greatly help users who experience problems due to the server-side issues; some users do not instinctively check the terminal messages, while others may not have access to those at all (thinking about end-users in JupyterHub/Google Colab-style deployments, or running as a desktop app started from a desktop shortcut). I think that having an option to redirect the server logs to frontend might be very useful for debugging in such settings. There is however a potential security consideration, so it might be best as an opt-in extension indeed.
