How to count the numer of pdf pages in python that has blank pdf page also

I have tried to print the count of pdf document which includes some blank white pdf page using pypdf module. But it avoids the blanks page and print the count of rest of pages. Below is the code.

import sys

import pyPdf

from pyPdf import PdfFileReader, PdfFileWriter

pdf_document = PdfFileReader(file(normalpdfpath,"r"))

normal = pdf_document.getNumPages()
print normal

You may try this, which worked for me:

import re
import os

rxcountpages = re.compile(r"/Type\s*/Page([^s]|$)", re.MULTILINE|re.DOTALL)

def count_pages(filename):
    data = file(filename,"rb").read()
    return len(rxcountpages.findall(data))

if __name__=="__main__":
    parent = "/Users/username/"
    os.chdir(parent)
    filename = 'LaTeX20120726.pdf'
    print count_pages(filename)

For Python 3.6+

import re

rxcountpages = re.compile(rb"/Type\s*/Page([^s]|$)", re.MULTILINE|re.DOTALL)

def count_pages(filename: str) -> int:
    with open(filename, "rb") as infile:
        data = infile.read()
    return len(rxcountpages.findall(data))

if __name__=="__main__":
    filename = '/Users/username/LaTeX20120726.pdf'
    print(count_pages(filename))

Just for all your googlers, here is an updated version of this answer and comment that works using built-in packages:

import re

# compile your regex to make it faster
PAGE_COUNT_REGEX = re.compile(
    rb"/Type\s*/Page([^s]|$)", 
    re.MULTILINE|re.DOTALL
)

def get_page_count(floc, regex=PAGE_COUNT_REGEX):
    """Count number of pages in a pdf"""
    with open(floc, "rb") as f:
        return len(regex.findall(f.read()))

get_page_count("path/to/your/file.pdf")

step 1:-

pip install pyPDF2

step 2:- 

import requests, PyPDF2, io
url = 'sample.pdf' 
response = requests.get(url)
with io.BytesIO(response.content) as open_pdf_file:
  read_pdf = PyPDF2.PdfFileReader(open_pdf_file)
  num_pages = read_pdf.getNumPages()
  print(num_pages)
