What is web scrapping?

Web scraping is a technique used to extract data from websites. It's like having a digital robot that visits web pages, reads the information displayed on those pages, and collects specific data of interest. This data can be anything from product prices and reviews to news articles or weather forecasts.

What is BeautifulSoup and Requests and how it will help us?

BeautifulSoup and Requests are two helpful tools that make web scrapping easier.

Imagine you want to extract specific information from a web page, such as the title of an article or the price of a product. BeautifulSoup is like a friendly librarian who helps you navigate through the messy web page and find exactly what you're looking for. BeautifulSoup is python library that makes it easy to scrape information from web pages by providing a simple API for parsing HTML and XML documents.

Requests, on the other hand, is like a messenger that delivers your request to the web server and brings back the web page's content. It helps you send a message to the web server, asking for the web page you're interested in. It is a widely-used Python library for making HTTP requests. It allows you to send GET and POST requests to web servers and handle the responses effortlessly. When combined with BeautifulSoup, Requests becomes a powerful tool for web scraping.

Installing the Required Libraries

pip install beautifulsoup4 requests

Sample Web Scrapping Programm

import requests
from bs4 import BeautifulSoup

# Send a GET request to the web page
url = "https://www.example.com"
response = requests.get(url)

# Create a BeautifulSoup object from the HTML content
soup = BeautifulSoup(response.content, "html.parser")

# Find and print all the headlines and summaries of news articles
articles = soup.find_all("article")
for article in articles:
    headline = article.find("h2").text
    summary = article.find("p").text

    print("Headline:", headline)
    print("Summary:", summary)
    print()

# Find and print the total number of images on the web page
images = soup.find_all("img")
total_images = len(images)
print("Total Images:", total_images)

# Find and print the form action URL
form = soup.find("form")
action_url = form.get("action")
print("Form Action URL:", action_url)

Conclusion

In short, web scraping with BeautifulSoup and Requests is a powerful way to extract data from websites. It automates the collection of valuable information like headlines, summaries, images, and form action URLs. Web scraping enables efficient data analysis and informed decision-making.
