I put together a Python Developer Kit with over 100 pre-built Python scripts covering data structures, Pandas, NumPy, Seaborn, machine learning, file processing, web scraping and a whole lot more - and I want you to have it for free.
= Content on page : 2 = Simple PDF File 2. pdf file - just for use in the Virtual Mechanics tutorials. = Content on page : 1 = A Simple PDF File This is a small demonstration. Here’s an example showing what we’ve covered so far: The object of the PdfFileReader class can then be used to read text from a PDF document. Once you open the file, the file handler returned by the open() method is passed to the constructor of the PdfFileReader class of the PyPDF2 module. Since PDF files contain data in binary format, the permission for the open() method should be set to rb (read binary). Next, you need to open the PDF file you want to read using the default Python open method. Now, let’s move on to extracting information from PDF.
To read a PDF file with Python, you first have to import the PyPDF2 module. pip install pypdf2 The installation process does not take much time as the PyPDF2 package doesn’t have any dependencies. If you open the file, you’ll see that it contains 2 pages with some dummy data.
Download this file and save it as “sample.pdf” to your local file system.
To demonstrate how to read a PDF file from your local drive, we’re going to use the PDF file found here. To install the PyPDF2 library, execute the following pip command on your command terminal. Scanned PDF documents which contain text in the form of images cannot be read by PyPDF2 so you’d need to find a way to OCR (optical character recognition) the images first. It’s important to mention that PyPDF2 can only read PDF documents that contain data in the form of text. PyPDF2 is an awesome Python library capable of reading PDF documents and writing text to a PDF file. We’ll show you how to read PDF documents in a Python application using PyPDF2. That’s what we’re going to talk about today.
In cases like this, you have to find a way to programmatically read PDF files in your applications.
To do that, you’d need to extract text from the PDF documents. Let’s say you want to develop a document classification application based on machine learning models trained on PDF documents. While several PDF readers and writers exist, you might think it’d be hard to extract text from a PDF programmatically. My sample PDF file has a PNG image on the first page and the program saved it with an “image20.png” filename.A PDF is the most commonly used file format for documents since PDFs are extremely light-weight and can be used cross-platform. If xObject = '/FlateDecode':Įlif xObject = '/DCTDecode':Įlif xObject = '/JPXDecode':Įlif xObject = '/CCITTFaxDecode': We can easily extend it further to extract all the images from the PDF file. Here is the simple program to extract images from the first page of the PDF file. We can use PyPDF2 along with Pillow (Python Imaging Library) to extract images from the PDF pages and save them as image files.įirst of all, you will have to install the Pillow module using the following command. The output files are named as Python_Tutorial_0.pdf and Python_Tutorial_1.pdf. With open(output_file_name, 'wb') as output_file: Pdf_reader = PyPDF2.PdfFileReader(pdf_file) With open('Python_Tutorial.pdf', 'rb') as pdf_file: We can also get the information about the PDF author, creator app, and creation dates. We can get the number of pages in the PDF file. PyPDF2 is a pure Python package, so you can install it using pip (assuming pip is in your systems path): python -m pip install pypdf2 As usual, you should install 3rd party Python packages to a Python virtual environment to make sure that it works the way you want it to. Let’s look at some examples to work with PDF files using the PyPDF2 module.
