Using Python to pull the number of pages in all the pdf documents in a directory

Question

I am trying to use PyPDF2 to grab the number of pages of every pdf in a directory. I can use .getNumPages() to find the number of pages in one pdf file but I need to walk through a directory and get the number of pages for every file. Any ideas?

Here is the code I have so far:

import pandas as pd
import os
from PyPDF2 import PdfFileReader
df = pd.DataFrame(columns=['fileName', 'fileLocation', 'pageNumber'])
pdf=PdfFileReader(open('path/to/file.pdf','rb'))
for root, dirs, files in os.walk(r'Directory path'):
    for file in files:
        if file.endswith(".pdf"):
            df2 = pd.DataFrame([[file, os.path.join(root,file),pdf.getNumPages()]], columns=['fileName', 'fileLocation', 'pageNumber'])
            df = df.append(df2, ignore_index=True)

This code will just add the number of pages from the first PDF file in the directory to the dataframe. If I try to add a directory path to PdfFilereader() I get a

PermissionError:[Errno 13] Permission denied.

Yeah, use

import glob
list_of_pdf_filenames = glob.glob('*pdf')

to return the list of all PDF filenames in a directory.

**Edit: **

By placing the open() statement inside the loop, I was able to get this code to run on my computer:

import pandas as pd
import os
from PyPDF2 import PdfFileReader
df = pd.DataFrame(columns=['fileName', 'fileLocation', 'pageNumber'])
for root, dirs, files in os.walk(r'/home/benjamin/docs/'):
    for f in files:
        if f.endswith(".pdf"):
            pdf=PdfFileReader(open(os.path.join(root, f),'rb'))
            df2 = pd.DataFrame([[f, os.path.join(root,f), pdf.getNumPages()]], columns=['fileName', 'fileLocation', 'pageNumber'])
            df = df.append(df2, ignore_index=True)
print(df.head)

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)

If you want to use newer pypdf version here is the code.

Only thing you need to install is pypdf

pip install pypdf

Than you can run:

from pathlib import Path
from typing import Mapping

from pypdf import PdfReader

directory = Path("C://YourDirToSearch/")

def get_num_pages(pdf_file: Path) -> int:
    reader = PdfReader(pdf_file)
    return len(reader.pages)

def get_pdf_page_numbers(directory: Path) -> Mapping[Path, int]:
    return {file: get_num_pages(file) for file in directory.glob("*.pdf")}

print(get_pdf_page_numbers(directory))

As a result you get something like:

{
 "path1.pdf": 1,
 "path2.pdf": 2,
}
