When I read something like "Python finally acquired an event loop in

Python perhaps for 2 decades...
As was pointed out to me just a few days ago, that’s Tcl, not Python.
Tk is part of Tcl/Tk. Tk's mainloop() calls level tcl loop functions.
The tkinter and _tkinter modules are Python stdlib modules. For
timer-based callbacks, there is little difference between using tkinter
and async modules. The fact that async uses a Python-coded event loop
while tkinter uses a Tcl-coded loop is nearly invisible. Several other
stdlib modules wrap 'foreign' code too.
