I was attempting to clarify the language that one "must run it from
cmd.exe". This only needs to be done if you need to keep the window
open after a console program has exited. Also, it doesn't have to be
cmd.exe. You can use powershell.exe, bash.exe, another instance of
python.exe, etc -- any console program that lets you start a child
process and wait for it to exit.

I often come across even experienced Windows programmers on Stack
Overflow who somehow have drawn the conclusion that cmd.exe *is the
console*. I take whatever opportunity I can get to correct this
misunderstanding with a little FYI note.

For a newbie, I would of course suggest IDLE. I may also suggest
changing the shebang to "#!python3 -i" while debugging a script. They
can double-click on the script's icon to run it, and after it's done
executing or if there's an unhandled exception, they can inspect the
result in the REPL.
