PDF Extract using CSV values

[atomxkai]

Hello, need help on how to read from CSV file with multiple values instead of manual input?

Thank you.

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()

# this values are manual input

setpage = 21
startpage = 524
endpage = 570

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)
    f.close()
