Creating read only pdf file using Python

问题:

Is there any python module using that we can create a new pdf file or modify the existing pdf file which have only read permission. I want to disable the "Save as" and "Save as to other formats" for the pdf file.(DRM things.)

I'm not sure this is portable, but you could use os.chmod:

import os
from stat import S_IREAD, S_IRGRP, S_IROTH

filename = "yourfile.pdf"
# Open the file and write your stuff to the file etc...

os.chmod(filename, S_IREAD|S_IRGRP|S_IROTH)
