I've been struggling with reading a text from a PDF in Python.

What I need is PyPDF2 to find a given string and return a reference number placed next to that string.

That's the code I'm trying:

import os
import shutil
import PyPDF2
from PyPDF2 import PdfFileWriter, PdfFileReader

jobpath = r"C:\Scrpts\scr\testPDF"

for files in os.listdir(jobpath):
        if files.endswith('.pdf'):
            filename = os.path.join(jobpath, files)
            with open(filename, 'rb') as pageObj1:

                pdfReader1 = PyPDF2.PdfFileReader(pageObj1)
                pdfReader1._override_encryption = True
                pageObj1 = pdfReader1.getPage(0)

                text1 = pageObj1.extractText()
                refNum = text1.partition("Reference")

                text1 = refNum[2]
                text1 = text1[0:30]
                a = 'Reference'
                b = '\n'
                text1 = text1.split(a)[-1].split(b)[0]
                refNum = text1
                print(filename + ' ' + refNum)

But this is giving a superfluous whitespace error:

C:\Scrpts\scr\testPDF\testPDF.pdf

I have used a similar script in the past without any problems.

I tried to search for similar issues, however, I am unable to find any solution.

  • I have the same issue (and no solution!) if a execute `getPage(0)` on a single pdf. You are iterating, haven't you tried to get the text of a single pdf and see if you get the warning? – cards Sep 19 '21 at 17:19

    I think the issue comes from PdfFileReader() method . add the strict argument to False. Its warning snot a fatal errors. I answered to the same problem in this topic . Check it if you need more explanations. https://stackoverflow.com/questions/70334338/errors-while-using-pyttsx3-pypdf2-for-making-an-audio-book – Wuzardor Feb 15 '22 at 23:59
