Note that the filenames that will be returned here are not fully
qualified: you'll just get filename.txt, not
/home/.../shortstories/filename.txt.

fileinput doesn't have the context of the directory that you listed
above, so it's just going to look in the current directory.

Although it's not the problem at hand, I think you'll find that you
need to qualify the filename() and filelineno() function calls with
the fileinput module.

And here you can see that it's failing to find the file because it's
looking in the wrong directory. You can use the os.path.join function
to add the proper directory path to the filenames that you pass to
fileinput.

The trailing ~ is a convention used by Emacs (and possibly other
editors) for files that it creates as backups.
