Addendum, some file objects have a name attribute (which I hadn't
noticed until today):

file.name
If the file object was created using open(), the name of the file.
Otherwise, some string that indicates the source of the file object,
of the form <...>. This is a read-only attribute and may not be
present on all file-like objects.
