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.
