Ah, right. In order to see output, you'll need to set the right javascript
callbacks to handle the resulting display messages. I think if you make
your python handler write to a file, you'll see the output in the file.
Alternatively, you can use an Output ipywidget to capture the output:
from ipywidgets import Output
out = Output()
def handle_comm_message(message):
with out:
print(message)
and then display the output widget in another cell somewhere
Thanks,
