Python 3.4: Temporary files not being deleted automatically

Question

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 is quite crucial for programs which would be used multiple times as its directory will get messy once the temporary files pile up.

Answer 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.
