This was very helpful!
The pages get added back out of order, it should be:
output.addPage(q)
output.addPage(p)

This is the error I get every time:

Where do I get this function from "file"? What is this "file" referencing to?
Can anyone help me how to do this on linux? I have no idea how to use it. I have installed pdf module and pyPDF module
Hacked up a 2024 update that uses python3 and newer library conventions:

Thanks for the original! Cheers.
Awesome, thanks
