#Do install the library if not available in the environment you are working on
#!pip install PyPDF2

from PyPDF2 import PdfFileWriter, PdfFileReader

pages_to_keep = [2, 4] # Remember that the page numbers would starts from 0. So Page number 1 will become 0 here.
infile = PdfFileReader('filename.pdf', 'rb')
output = PdfFileWriter()

for i in pages_to_keep:
    p = infile.getPage(i)
    output.addPage(p)

with open('Output.pdf', 'wb') as f:
    output.write(f)
