How do I stop Python IDLE (GUI) from immediately exiting when I enter it?

All this looks like a script with an endless loop in it. But in the code
you posted there is no loop at all.

Then I suppose you typed the script again from scratch? Possibly you had
some error in it that didn't show in your posting. But I don't think that
can be cleared up now.

If that happens: try your script in the command window. And if at all
possible, look at it in a hex viewer to find not printable characters that
might corrupt the file. And post again, but be sure to cut and paste your
code.
