Permission Denied To Write To My Temporary File

Question

I am attempting to create and write to a temporary file on Windows OS using Python. I have used the Python module tempfile to create a temporary file.

NamedTemporaryFile actually creates and opens the file for you, there's no need for you to open it again for writing. In fact, the Python docs state:

Whether the name can be used to open the file a second time, while the named temporary file is still open, varies across platforms (it can be so used on Unix; it cannot on Windows NT or later).

That's why you're getting your permission error. What you're probably after is:

f = tempfile.NamedTemporaryFile(mode='w') # open file
temp = f.name                             # get name (if needed)
