We cannot make that promise, because we might not have permission to view the file.

And if the path is an illegal value, it also straight doesn't exist. Like the empty string, like "<" on Windows, like strings with too many path components. -- Steven D'Aprano "Ever since I learned about confirmation bias, I've been seeing it everywhere." -- Jon Ronson -- https://mail.python.org/mailman/listinfo/python-list
