How to create a new PDF file and a sheet in it?

Question

Python

You need to create a PDF document and add two images to it.
Using the pdfrw library, I cannot do this, because to create a page, the writer.addpage() method requires the page of an already existing document as an argument.
Here's what he wants to see:

from pdfrw import PdfWriter,PdfReader

def pdf():
    writer = PdfWriter()
    reader = PdfReader('file.pdf')
    writer.addpage(reader.pages[0]) #этот самый метод, создающий страницу в документе pdf
    writer.write('file.pdf')

And you just need to create a document from scratch without opening any other document using PdfReader'a.
Is it possible to create a document from scratch by adding the desired images to it?
