Good point. I am using that seldom the notebook that I did not even
think about it :-) Let me try ... Ok, as I expected, it's not that graceful:
Traceback (click to the left for traceback)
...
AttributeError: 'NoneType' object has no attribute 'to_user_ns'
Is there an easy way to manipulate the global namespace for the
notebook? For IPython, I am using:
import IPython
ip = IPython.ipapi.get()
ip.to_user_ns( dict( ... ) )
Cheers,
Nicolas
