PdfWriter instances have the .append_pages_from_reader() method, which you can use to append pages from a PdfReader instance. To use .append_pages_from_reader(), pass a PdfReader instance to the method’s reader parameter. For example, the following code copies every page from the Pride and Prejudice PDF to a PdfWriter instance:
Within that function, you will need to create a writer object that you can name pdf_writer and a reader object called pdf_reader. Next, you can use .GetPage() to get the desired page. Here you grab page zero, which is the first page. Then you call the page object’s .rotateClockwise() method and pass in 90 degrees.
