Question

What is the way to rename the following tempfile

pdf = render_me_some_pdf() #PDF RENDER
f = tempfile.NamedTemporaryFile()
f.write(pdf)
f.flush()

I read somethings about os.rename but I don’t really now how to apply it

Answer 1

You can access the filename via f.name. However, unless you use delete=False python will (try to) delete the temporary file automatically as soon as it is closed. Disabling auto deletion will keep the tempfile even if you do not save it – so that’s not such a good idea.

The best way is copying the file and letting python delete the temporary one when it’s closed:

import shutil
shutil.copy(f.name, 'new-name')
