I just upgraded to Emacs 26.1 on Linux (Ubuntu 18.04, but emacs26 from the kelleyk repo).
python-mode is now bringing up a *Python-Help* window whenever the cursor in on a symbol or keyword. I'm finding this very distracting because it messes with my buffer layout and moves the cursor around.
It's a nice idea, but I don't want it happening automatically.
How can I disable the automatic *Python-Help* window?
