Python 3.4: Temporary Files Not Being Deleted Automatically

If you're using the tempfile library, then you might have experienced the scenario where the temporary file is not being automatically deleted even your program has completed. This

Solution 1:

This is Q&A. Hence, here's my solution.

Apparently, the default settings for the tempfile.TemporaryFile does not automatically delete your temporary file, but adding a prefix in your tempfile.NamedTemporaryFile works:

with tempfile.NamedTemporaryFile(prefix="anything_",
                                         dir=os.getcwd()) as tempf:

            '''put something'''
            tempf.seek(0)

Notes:

• The os.getcwd() is to get the current directory of your file.
• Your temporary file would be anything_ + (random values) (i.e anything_23mem)

Hope it helps.
