I am using tempfile.TemporaryFile for some intermediate processing. The program nicely removes the temp file for me when it closes, which is precisely the behaviour that I want the majority of the time. But is there a way to save the file for examination in the event of a (trapped) error or other abnormal circumstance?

Seek to the beginning and use shutil.copyfileobj() to copy the data to a file you create.

Use tempfile.mkstemp(). According to the documentation:
Unlike TemporaryFile(), the user of mkstemp() is responsible for deleting the temporary file when done with it.

Thanks. It looks like this would work, but it seems to add a lot more complexity compared with shutil.copyfileobj() – TimothyAWiseman Apr 12 '12 at 17:47
