Replace a Specific page in a PDF with a page from another PDF in python 3
Get a word processor or page layout software. Convert PDF to format your software can read. Edit document. Write new PDF.
Anything else sounds nefarious. Nobody should help you do it any other way.
I am using pypdf2 to highlight text in a particular page in Pdf files.Hence,I get only a single page with higlighted text as an output.Now,I want to replace this page in the original pdf file.
I have also tried "search=" parameter from abode to highlight in the same file itself.But,It is not working.
I am new to working  with PDFs.Sorry,If the question sounded a bit naive.
