Reading pdf files line by line using python

I used the following code to read the pdf file, but it does not read it. What could possibly be the reason?

>>> import os 

>>> from PyPDF2 import PdfFileReader, PdfFileWriter

>>> path = "/Users/Rahul/Desktop/Dfiles/"

>>> dirs = os.listdir( path )

>>> directory = "/Users/Rahul/Desktop/Dfiles/106_2015_34-76357.pdf"

>>> f = open(directory, 'rb')

>>> reader = PdfFileReader(f)

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

>>> f.close()

>>> print contents

The output is [u''] instead of reading the content.

import re
import PyPDF2

pdfFileObj = open('E://drive-download-20171015T225604Z-001/test_case/test2/try/xyz.pdf', 'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
print("Number of pages:-"+str(pdfReader.numPages))
num = pdfReader.numPages
i =0
while(i<num):
    pageObj = pdfReader.getPage(i)
    text=pageObj.extractText()
    text1 = text.lower()
    for line in text1:
        if(re.search("abc",line)):
            print(line)
    i= i+1

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

How to read the PDF file line by line using Python, import re import PyPDF2 pdfFileObj = open('E://drive-download- 20171015T225604Z-001/test_case/test2/try/xyz.pdf', 'rb') pdfReader = PyPDF2� Is there a way to read line by line from the pdf file (not pages) using Pypdf, Python 2.6, on Windows? Here is the code for reading the pdf pages: import pyPdf def getPDFContent(path): content = "" num_pages = 10 p = file(path, "rb") pdf = pyPdf.PdfFileReader(p) for i in range(0, num_pages): content += pdf.getPage(i).extractText() + " " content = " ".join(content.replace(u"\xa0", " ").strip().split()) return content.

May be this can help you to read PDF.

import pyPdf
def getPDFContent(path):
    content = ""
    pages = 10
    p = file(path, "rb")
    pdf_content = pyPdf.PdfFileReader(p)
    for i in range(0, pages):
        content += pdf_content.getPage(i).extractText() + "\n"
    content = " ".join(content.replace(u"\xa0", " ").strip().split())
    return content

Reading pdf files line by line using python, In this tutorial, we'll be reading a big file line by line in Python with the read, readline and readlines functions - through hands-on examples. 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

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

Read a File Line-by-Line in Python, Reading a File Line by Line. Instead of reading all the contents of the file at once, we can also read the file contents line by line. To do so, we� Now its turn for the actual code, But one Important thing to understand is that there is no direct method in PyPDF library to read PDF file line by line, it always read it as a whole (using ‘extractText ()’ function), but one good thing to knew, that it always returns the ‘String’ as an output.

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

Python for NLP: Working with Text and PDF Files, To install PyPDF2, run following command from command line: class of PyPDF2 module and pass the pdf file object & get a pdf reader object. This final way of reading in a file line-by-line includes iterating over a file object in a for loop. Doing this we are taking advantage of a built-in Python functionality that allows us to iterate over the file object implicitly using a for loop in combination of using the iterable object. This approach takes fewer lines of code, which is always the best practice worthy of following.

Hello Rahul Pipalia,

If not install PyPDF2 in your python so first install PyPDF2 after use this module.

Installation Steps for Ubuntu (Install python-pypdf)
  1. First, open terminal
  2. After type sudo apt-get install python-pypdf
Your Probelm Solution

Try this below code,

# Import Library
import PyPDF2

# Which you want to read file so give file name with ".pdf" extension
pdf_file = open('Your_Pdf_File_Name.pdf')
read_pdf = PyPDF2.PdfFileReader(pdf_file)
number_of_pages = read_pdf.getNumPages()

#Give page number of the pdf file (How many page in pdf file).
# @param Page_Nuber_of_the_PDF_file: Give page number here i.e 1
page = read_pdf.getPage(Page_Nuber_of_the_PDF_file)

page_content = page.extractText()

# Display content of the pdf
print page_content

I hope my answer is helpful. If any query so comments, please.

Working with PDF files in Python, So this works great. But now I need to print the line out of a PDF-File. But I only get the hole text out of it. Here my code:� Readline() to read file line by line. When the file size reaches to MBs or in GB, then the right idea is to get one line at a time. Python readline() method does this job efficiently. It does not load all data in one go. The readline() reads the text until the newline character and returns the line.

  • Does it work for other page numbers than 0? Are you sure there is text in the PDF, and not just images or graphics?
