Good to hear you can run your program. For future reference, when you
talked about setting PYTHONPATH, it would have been helpful to know just
what you did when you tried to set it.

If you plan to use this directory location much of the time, two good
ways to do so are 1) putting that path in a .pth file in the
site-packages directory, or 2) launching Python using a batch file that
sets PYTHONPATH first, then runs Python. On Windows, in a batch file
you should use SETLOCAL before setting PYTHONPATH and ENDLOCAL at the
end of the batch file. That's the easiest way to remove the PYTHONPATH
variable after you are done with it.

You made a little slam against Windows, but you will find it harder to
get things working on Linux. Ubuntu, like many other Linux distros,
does not come with pip and Tk (needed for Idle) installed, and it's not
so obvious how to install them.

For your old computer, I added an external 1TB solid state drive (Note:
not a usb stick) to a decade-old Sony VAIO and installed Linux Mint to
the SSD. It's got pretty decent responsiveness and all the old hardware
is supported out of the box.
