Thanks for raising this. I just ran your example and it worked fine. Your error looks like it's caused by the Python parser failing to parse the source code. Could...

I have been able to reproduce this by running Python 3.7. I believe the issue is with the underlying ipywidgets embedding code. I will investigate this further. Re-opening this for...

For anyone interested in this, I suggest tracking [PR 2278](https://github.com/jupyter-widgets/ipywidgets/pull/2278) on ipywidgets.

I'd recommend using a virtual environment with Python 3.6. I believe IPywidgets has several incompatibilities with Python 3.7 at the moment.

I would recommend asking that directly in [ipywidgets](https://github.com/jupyter-widgets/ipywidgets), where any answer is likely to be more useful and seen by more people.

Thanks very much for submitting a work-around -- it's really valuable!
