Seems not to be a reliable way of checking if the code is run in a notebook

@sebastianruder when I test this in my notebook cfg['IPKernelApp']['parent_appname'] returns a traitlets.config.loader.LazyConfigValue object. Please see this stackoverflow's thread. Thanks for the added feature!

Thanks for pointing this out! Are you aware of something that works reliably? The SO thread also seems to be somewhat split on what's the best way to do this.

Not really, but maybe using get_ipython().class.name == 'ZMQInteractiveShell' would be better, for the time being.

Created a PR - not sure if this is the solution we would like to go with but if that would be the case the PR is ready 🙂

Be careful in @mcallara 's answer
get_ipython().__class__.__name__
(You didn't escape the underscores...)
