information = [("WhatIsCMS",18,45)]
 
for page in range(len(information)):
    pdf_writer = PdfFileWriter()
    start = information[page][1]
    end = information[page][2]
    while start<=end:
        pdf_writer.addPage(pdfReader.getPage(start-1))
        start+=1
    if not os.path.exists("./"):
        os.makedirs(savepath)
    output_filename = '{}_{}_page_{}.pdf'.format(information[page][0],information[page][1], information[page][2])
    with open(output_filename,'wb') as out:
        pdf_writer.write(out)

# pypdf2_ex2.py
import os
from PyPDF2 import PdfFileWriter, PdfFileReader
 
pdfReader = PdfFileReader(open("Beginning-Git-and-GitHub.pdf", "rb"))
information = [("GitAndGithub",17,105),("GitAndGithub",107,194),("GitAndGithub",196,289)]
 
for page in range(len(information)):
    pdf_writer = PdfFileWriter()
    start = information[page][1]
    end = information[page][2]
    while start<=end:
        pdf_writer.addPage(pdfReader.getPage(start-1))
        start+=1
    if not os.path.exists("./"):
        os.makedirs(savepath)
    output_filename = '{}_{}_page_{}.pdf'.format(information[page][0],information[page][1], information[page][2])
    with open(output_filename,'wb') as out:
        pdf_writer.write(out)

# pypdf2_ex3.py
# merge several pdf files
import sys
import PyPDF2
 
pdf_write_object = PyPDF2.PdfFileWriter()
 
#for i in sys.argv[1:]:
for i in ["WhatIsCMS.pdf","InforLifeCycle.pdf","EnterpriseContentManage.pdf"]:
    pdf_read_object = PyPDF2.PdfFileReader(i)
    print('processing file : '+ i + 'number of pages : ' +  str(pdf_read_object.numPages))
    for page in range(pdf_read_object.numPages):
        pdf_write_object.addPage(pdf_read_object.getPage(page))
 
final_file_object = open('2020CMS.pdf', 'wb')
pdf_write_object.write(final_file_object)
final_file_object.close()
