Or, maybe I am reading the documentation incorrectly. My goal is to
be able to write to that temporary file along the lines of "f.write()"
or "with open(f) as writer ...".
NamedTemporaryFile by default opens a file in binary mode ('w+b'). Write
bytes or specify text mode.
>>> f.write(b"Hello World!\n")
13
>>> ft = NamedTemporaryFile('w+', delete=False)
>>> ft.write("Hello World!\n")
13
