pyPDF2 merge 2 pdf pages into one

from PyPDF2 import PdfFileReader, PdfFileWriter

# this defines the output page format (relevant if not the same)

Thank you. I just used your example to complete one exercise from the online Python course I'm on. I didn't want to check the answer before I solve it myself (with googling). I modified it a little, as per my needs. Yet, my mentor's solution was somewhat better. I actually don't need to create a new PageObject, I can just merge what is invoice_page in your example with the other page(s). If I need to work with pdf files in the future, I'll probably just google 'pdf python' and choose the most popular library. But your work helped me for now, thank you for that and your advice too.

As noted by @dreua below, this has been addressed in the code posted here. I'm going to leave an edited version of this note though because others may still find code with from PyPDF2.pdf import PageObject in places and wonder about the difference.

Note that the second import statement of this code was outdated up until last week with regards to current use. Here in the documentation for PyPDF it states: "PyPDF2.pdf no longer exists. You can import from PyPDF2 directly". So the second import line became from PyPDF2 import PageObject. Otherwise, you get the error ModuleNotFoundError: No module named 'PyPDF2.pdf'.

@fomightez Thank you, I just edited this Gist accordingly.
