How to overwrite specific page of PDF with another page of another PDF with Python's PyPDF2

Question:

I want to overwrite the first page of a PDF with another page of another PDF using the PyPDF2 library in Python.

For more detail, I have two separate PDFs (let’s call them overwritten.pdf and other.pdf) and I want to replace the first (it doesn’t have to be the first) page of overwritten.pdf with a specific page of other.pdf so the first page of overwritten.pdf is that specific page of other.pdf.

I don’t know if you can literally "replace a page" with PyPDF2. I would use the merge function. Example from the PyPDF2 web site:

from PyPDF2 import PdfMerger

merger = PdfMerger()

input1 = open("document1.pdf", "rb")
input2 = open("document2.pdf", "rb")
input3 = open("document3.pdf", "rb")

# add the first 3 pages of input1 document to output
merger.append(fileobj=input1, pages=(0, 3))

# insert the first page of input2 into the output beginning after the second page
merger.merge(position=2, fileobj=input2, pages=(0, 1))

# append entire input3 document to the end of the output document
merger.append(input3)

# Write to an output PDF document
output = open("document-output.pdf", "wb")
merger.write(output)

# Close File Descriptors
merger.close()
output.close()

You can try merging the PDFs with the PdfMerger tool from PyPDF2
