Looking at .name
on a file handle is indeed one way to see where the file exists. In the case of TemporaryFile
(on *NIX systems), you'll see <fdopen>
, indicating an open file handle, but no corresponding directory entry. You'll need to use NamedTemporaryFile
if you'd like to preserve the link to the underlying file.
If you wish to control where temporary files go, look at the dir
parameter:
TemporaryFile
uses mkstemp
, which allows setting the directory with the dir
parameter:
If
dir
is specified, the file will be created in that directory; otherwise, a default directory is used. The default directory is chosen from a platform-dependent list, but the user of the application can control the directory location by setting theTMPDIR
,TEMP
orTMP
environment variables.
