The file you create with TemporaryFile or NamedTemporaryFile is automatically removed when it's closed, which is why you get an error. If you don't want this, you can use mkstemp instead (see the docs for tempfile).

>>> import tempfile, shutil, os
>>> fd, path = tempfile.mkstemp()
>>> os.write(fd, 'foo')
>>> os.close(fd)
>>> shutil.copy(path, 'bar.txt')
>>> os.remove(path)
