[docs] [issue27579] Add a tutorial for AsyncIO in the documentation

Terry J. Reedy added the comment: 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. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue27579> _______________________________________
