PDF Extract using CSV values

[BashBedlam]

Assuming that your csv file looks something like this:

Set Page, Start Page, End Page
2, 4, 8
2, 10, 14
2, 16, 20 

Then this will do what you're asking:

from PyPDF2 import PdfFileReader, PdfFileWriter
 
pdf_file_path = 'document.pdf'
file_base_name = pdf_file_path.replace('.pdf', '')
 
pdf = PdfFileReader(pdf_file_path)
 
pdfWriter = PdfFileWriter()
 
with open ('page values.csv', 'r') as page_values_file :
	page_values_file.readline () # dump the header

	for line in page_values_file :
		page_values = line.strip ().split (',')
		setpage = int (page_values [0])
		startpage = int (page_values [1])
		endpage = int (page_values [2])

		for page_num in range(startpage,endpage):
			pdfWriter.addPage(pdf.getPage(page_num))
 
		with open("%(n)s_subset_%(b)s.pdf" % {'n': format(file_base_name), 'b': setpage }, 'wb') as f:
			pdfWriter.write(f)
