('je'+'di').upper().<tab>
. . . the only completion I get is "ipynb_checkpoints/", which seems to be some kind of global generic completion.
The reason I'm asking here on Jupyter list is that the completion works correctly if I try it in a console IPython session. So it seems something is misconfigured
between IPython and Jupyter. Do I need to do something special to get this new completion working in Jupyter?
