Permissions issues with zipfile

[loial]

I am getting a permission issue with the following code


            targetdirectory = '/data/upload'

            self.ZIPFileName = targetDirectory + os.sep + "MY.ZIP" 

            zf = zipfile.ZipFile(self.ZIPFileName, mode='w') 


 [Errno 13] Permission denied: '/data/upload/MY.ZIP' 



The target directory is an NFS mounted directory.

I can manually create a file in that directory with no issues using the same user

Any ideas?

Python version is 2.7.10. Platform is Centos 7
