Could you use tempfile.TemporaryDirectory and then just use a consistent
name within that directory.

It's guaranteed not to exist because the directory was only just created
and only you can write to it? Has the added bonus of still being reasonably
secure, to appease people like Mr PointedEars.

(If you need multiple nonexistent paths in the same dir then perhaps use
tempfile.NamedTemporaryFile with your newly created temp dir and an
arbitrary suffix, and strip the suffix off to get the name you actually
use.)
