This gives a SyntaxError if there's an unescaped quote in the path or file name (such as /home/cheryl's/tests/).
Using triple quotes works:
f"__file__ = r'''{os.path.abspath(filename)}'''\n"

Great catch. Changed.

Set __file__ while running a startup file. Like Python, IDLE optionally
runs one startup file in the Shell window before presenting the first
interactive input prompt. For IDLE, -s runs a file named in
environmental variable :envvar:IDLESTARTUP or :envvar:PYTHONSTARTUP;
-r file runs file. Python sets __file__ to the startup file
name before running the file and unsets it before the first prompt. IDLE now
does the same when run normally, without the -n option.

Thanks. by 'editing', I could see and copy the markup (and maybe learn better). I changed one clause to -r file runs file, which I can preview here ;-).
