I'm trying to download versions of Python and Pil which are compatible with each other.
I could be wrong, I could be right, but there doesn't seem to be any crossover.
You want Pillow which is effectively the replacement for PIL. You still from PIL import.... I successfully installed it on Python 3.8 to answer your question the other day.
Use conda (either anaconda or miniconda if you're in a hurry). You might have a better chance of getting the versions to match?
Create a new environment (where you can also specify which python version you want to use) and install pillow from conda-forge. All in the docs for conda.
