How Its Work?

1. PyPDF2 Tutorial :

PyPDF2 is a Python library that allows you to work with PDF files.

pip install PyPDF2

– Reading PDFs: PyPDF2 allows you to open and read PDF files. You can open a PDF file using the `PdfFileReader` class:

import PyPDF2

# Open the PDF file

pdf_file = open(‘example.pdf’, ‘rb’)

# Create a PDF reader object

pdf_reader = PyPDF2.PdfFileReader(pdf_file)

– Extracting Text: You can extract text from PDF files using PyPDF2. Each page of the PDF can be accessed using the `getPage()` method, and then you can extract text from the page using the `extract text()` method:

# Get the first page

first_page = pdf_reader.getPage(0)

# Extract text from the first page

text = first_page.extract text()


– Manipulating PDFs: PyPDF2 also allows you to manipulate PDF files, such as merging multiple PDFs, splitting PDFs, rotating pages, adding watermarks, etc.

– Writing PDFs: You can also create new PDF files or modify existing ones using PyPDF2. You can create a new PDF file using the `PdfFileWriter` class and add pages to it:

 # Create a PDF writer object

pdf_writer = PyPDF2.PdfFileWriter()

# Add a page to the PDF


# Write the PDF content to a new file

with open(‘output.pdf’, ‘wb’) as output_file:


2. Web Scraping in Python:

Web scraping is the process of extracting information from websites. 

– Fetching Web Pages: Python provides several libraries for fetching web pages, such as `requests` or `urllib`. You can use these libraries to send HTTP requests to a URL and retrieve the HTML content of the web page.
– Parsing HTML: Once you have fetched the web page, you need to parse the HTML content to extract the information you need. You can use libraries like `Beautiful Soup` or `lxml` for parsing HTML in Python.
– Extracting Data: After parsing the HTML, you can extract the desired data using various methods such as searching for specific HTML tags, using CSS selectors, or XPath expressions.
– Storing Data: Once you have extracted the data, you can store it in various formats such as CSV, JSON, or a database.
When combining both topics, you can use web scraping to extract text or other content from PDF files available online. For example, you can fetch PDF files from websites using web scraping techniques and then use PyPDF2 to extract text from those PDF files.
