Permission Denied To Write To My Temporary File
python, temporary-files
Solution
`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 something like:
f = tempfile.NamedTemporaryFile(mode='w') # open file
temp = f.name # get name (if needed)
Problem
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. But when I go to write that temporary file I get an error `Permission Denied`. Am I not allowed to write to temporary files?! Am I doing something wrong? If I want to create and write to a temporary file how should should I do it in Python? I want to create a temporary file in the temp directory for security purposes and not locally (in the dir the .exe is executing). `IOError: [Errno 13] Permission denied: 'c:\\users\\blah~1\\appdata\\local\\temp\\tmpiwz8qw'` ``` temp = tempfile.NamedTemporaryFile().name f = open(temp, 'w') # error occurs on this line ```
