For both TemporaryFile and NamedTemporaryFile, the rationale is that "temporary" extends until the object is garbage collected. TemporaryFile is deleted immediately (to prevent other applications from modifying your temporary file). NamedTemporaryFile is inteded for use when you need access to the file by filename during the lifetime of the file. In either case, when the object goes, the file should too.
