Quick way to save a python TempFile?

问题:

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?

回答1:

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



回答2:

Use tempfile.mkstemp(). According to the documentation:

Unlike TemporaryFile(), the user of mkstemp() is responsible for deleting the temporary file when done with it.
