Reading pdf files line by line using python

import re
from PyPDF2 import PdfFileReader

reader = PdfFileReader("example.pdf")

for page in reader.pages:
    text = page.extractText()
    text_lower = text.lower()
    for line in text_lower:
        if re.search("abc", line):
            print(line)

I use it to iterate page by page of pdf and search for key terms in it and process further.

I think you need to specify the disc name, it's missing in your directory. For example "D:/Users/Rahul/Desktop/Dfiles/106_2015_34-76357.pdf". I tried and I can read without any problem.

Or if you want to find the file path using the os module which you didn't really associate with your directory, you can try the following:

from PyPDF2 import PdfFileReader
import os

def find(name, path):
    for root, dirs, files in os.walk(path):
        if name in files:
            return os.path.join(root, name)

directory = find('106_2015_34-76357.pdf', 'D:/Users/Rahul/Desktop/Dfiles/')

f = open(directory, 'rb')

reader = PdfFileReader(f)

contents = reader.getPage(0).extractText().split('\n')

f.close()

print(contents)

The find function can be found in Nadia Alramli's answer here Find a file in python

To Read the files from Multiple Folders in a directory, below code can be used- This Example is for reading pdf files:

import os
from tika import parser

path = "/usr/local/" # path directory
directory=os.path.join(path)
for r,d,f in os.walk(directory): #going through subdirectories
    for file in f:
        if ".pdf" in file:  # reading only PDF files
            file_join = os.path.join(r, file)   #getting full path 
            file_data = parser.from_file(file_join)     # parsing the PDF file 
            text = file_data['content']               # read the content 
            print(text)                  #print the content

def getTextPDF(pdfFileName,password=''):
    import PyPDF2
    from PyPDF2 import PdfFileReader, PdfFileWriter
    from nltk import sent_tokenize
    """ Extract Text from pdf  """
    pdf_file=open(pdfFileName,'rb')
    read_pdf=PyPDF2.PdfFileReader(pdf_file)
    if password !='':
        read_pdf.decrypt(password)
    text=[]
    for i in range(0,read_pdf.getNumPages()):
        text.append(read_pdf.getPage(i).extractText())
    text = '\n'.join (text).replace("\n",'')
    text = sent_tokenize(text)
    return text

The issue was one of two things: (1) The text was not on page one - hence a user error. (2) PyPDF2 failed to extract the text - hence a bug in PyPDF2.

Sadly, the second one still happens for some PDFs.
