Do all file-like objects in the Python standard library have a `name` attribute?

Question

Basic file objects have a name attribute i.e.

>>> open("/dev/null").name
'/dev/null'

Do all other file-like types (e.g. GzipFile) in the standard library have this attribute?

Answer 1

No, for example a StringIO is a file-like object without name attribute. Most objects that are associated to an actual file have it, but it is not guaranteed.
