PDF and Word documents are binary files, which makes them much more complex than plaintext files. In addition to text, they store lots of font, color, and layout information. If you want your programs to read or write to PDFs or Word documents, youll need to do more than simply pass their filenames to open. Fortunately, there are Python modules that make it easy for you to interact with PDFs and Word documents. TakeE2.png' alt='Python File Encryption Module' title='Python File Encryption Module' />This chapter will cover two such modules Py. PDF2 and Python Docx. PDF stands for Portable Document Format and uses the. Getting Started on Heroku with Python Introduction. This tutorial will have you deploying a Python app a simple Django app in minutes. Hang on for a few more. Although PDFs support many features, this chapter will focus on the two things youll be doing most often with them reading text content from PDFs and crafting new PDFs from existing documents. The module youll use to work with PDFs is Py. PDF2. To install it, run pip install Py. SYDiY.png' alt='Python File Encryption Module' title='Python File Encryption Module' />PDF2 from the command line. This module name is case sensitive, so make sure the y is lowercase and everything else is uppercase. Check out Appendix A for full details about installing third party modules. If the module was installed correctly, running import Py. PDF2 in the interactive shell shouldnt display any errors. Extracting Text from PDFs. Py. PDF2 does not have a way to extract images, charts, or other media from PDF documents, but it can extract text and return it as a Python string. To start learning how Py. PDF2 works, well use it on the example PDF shown in Figure 1. Figure 1. 3 1.  The PDF page that we will be extracting text from. Download this PDF from http nostarch. Py. PDF2. pdf. File.

To extract text from a page, you need to get a Page object, which represents a single page of a PDF, from a Pdf. File. Reader object. You can get a Page object by calling the get.

Frequently Asked Questions. Overview. What is Pushover and how do I use it How much does Pushover cost Can I integrate Pushover into my own iOS. Py. PDF2 uses a zero based index for getting pages The first page is page 0, the second is Introduction, and so on. This is always the case, even if pages are numbered differently within the document. For example, say your PDF is a three page excerpt from a longer report, and its pages are numbered 4. To get the first page of this document, you would want to call pdf. Reader. get. Page0, not get. Page4. 2 or get. Page1. Once you have your Page object, call its extract. Text method to return a string of the pages text. The text extraction isnt perfect The text Charles E. Chas Roemer, President from the PDF is absent from the string returned by extract. Text, and the spacing is sometimes off. Still, this approximation of the PDF text content may be good enough for your program. Some PDF documents have an encryption feature that will keep them from being read until whoever is opening the document provides a password.

Encrypted attribute that is True if the PDF is encrypted and False if it isnt. Any attempt to call a function that reads the file before it has been decrypted with the correct password will result in an error. To read an encrypted PDF, call the decrypt function and pass the password as a string. After you call decrypt with the correct password, youll see that calling get. Page no longer causes an error. If given the wrong password, the decrypt function will return 0 and get. Page will continue to fail. Note that the decrypt method decrypts only the Pdf. File. Reader object, not the actual PDF file. After your program terminates, the file on your hard drive remains encrypted. Your program will have to call decrypt again the next time it is run. Py. PDF2s counterpart to Pdf. File. Reader objects is Pdf. File. Writer objects, which can create new PDF files. But Py. PDF2 cannot write arbitrary text to a PDF like Python can do with plaintext files. Instead, Py. PDF2s PDF writing capabilities are limited to copying pages from other PDFs, rotating pages, overlaying pages, and encrypting files. Py. PDF2 doesnt allow you to directly edit a PDF. Instead, you have to create a new PDF and then copy content over from an existing document. The examples in this section will follow this general approach Open one or more existing PDFs the source PDFs into Pdf. File. Reader objects. Create a new Pdf. File. Writer object. Copy pages from the Pdf. File. Reader objects into the Pdf. File. Writer object. Finally, use the Pdf. File. Writer object to write the output PDF. Creating a Pdf. File.

Writers write method. The write method takes a regular File object that has been opened in write binary mode. You can get such a File object by calling Pythons open function with two arguments the string of what you want the PDFs filename to be and wb to indicate the file should be opened in write binary mode. If this sounds a little confusing, dont worryyoull see how this works in the following code examples. You can use Py. PDF2 to copy pages from one PDF document to another. This allows you to combine multiple PDF files, cut unwanted pages, or reorder pages. Download meetingminutes. PDFs in the current working directory.
