I would like the tutorial to include something like the following.

Adding Tkinter GUI to Asyncio Program
-------------------------------------

Assuming that the tkinter Tk instance is called 'root' and the asyncio loop is called 'loop', add the following callback loop.

def tk_update():
    root.update()
    loop.call_soon(tk_update)

Before each loop.run_forever() or loop.run_until_complete(...) call, add

tk_update()

Do not call root.mainloop() or root.quit().  Loop.stop() or completion of run_until_complete will stop the tk_update loop.
---

This is the result of my experiments in #27546.  One of my tests was running IDLE with an asyncio loop augmented with the above replacing root.mainloop.  I don't yet know how to work with git and github.
