To be pedantic, you can only write *bytes* to files, so you need to
serialize your lists (or other objects) to strings and then encode
those to bytes; or skip the string and encode your list/object
directly to bytes.

Though unfortunately, I now have a tweaked version of that late-night

DIRECTLY TO BYTES! PICKLE: SERIALIZE DIRECTLY TO BYTES!"
