Python - Go through only 5 pages at one time in PyMuPdf Fitz

Question

• I want to iterate through the last 5 pages of a PDF in PyMuPdf , and ask the user if he wants to iterate through more 5 pages.
• I came across reversed method of PyMuPdf , but that doesn't take the parameter of limiting it to only 5 pages.
• Example, total 20 pages in a PDF. First process Page no. 16 to 20 in reverse order ie 20-19-18-17-16 and if the user enters Yes to process another 5 pages then process 15-14-13-12-11 and so on.
• doc.pages(start, stop, step) this method can be used for iterating through particular number of pages, but then I have to manually calculate the start and end, and do which is not a good practice.

Answer 1

Look at the Document.pages() iterator. Simply iterate over Document.pages(-5) which will yield the last 5 pages.

Answer 2

Use doc.page_count

1. Create a list of the page numbers, in your case it is the last 5 pages .
2. Use the syntax last_pages=list(range(doc.page_count-5,doc.page_count))
3. Iterate through the list representing the page numbers.
