Web scraping is a powerful technique used to extract data from websites. Python provides excellent libraries like requests and BeautifulSoup that simplify the process. In this tutorial, we will walk through a complete example of web scraping using Python. By the end, you’ll be equipped with the knowledge to gather data from websites and utilize it in your projects.

Before we begin, ensure you have the following:

  • Python installed on your machine (preferably Python 3.x)
  • Basic understanding of Python programming concepts

Step 1: Installing Required Libraries:
To start, we need to install the necessary libraries. Open your terminal or command prompt and execute the following commands:

pip install requests
pip install beautifulsoup4

Step 2: Importing Libraries:
Create a new Python file and import the required libraries:

import requests
from bs4 import BeautifulSoup

Step 3: Sending a Request:
Choose a webpage you want to scrape. In this example, we’ll extract the title from a Wikipedia page. Send a GET request to the webpage and retrieve its HTML content:

url = ""
response = requests.get(url)

Step 4: Parsing HTML Content:
Create a BeautifulSoup object to parse the HTML content and navigate through its elements:

soup = BeautifulSoup(response.content, "html.parser")

Step 5: Extracting Data:
Using the BeautifulSoup object, find the relevant HTML element(s) containing the data you want to extract. In this case, we’ll extract the page title:

title = soup.find("h1", {"id": "firstHeading"})
print("Title:", title.text)

Step 6: Additional Data Extraction:
You can explore further and extract more data by finding other HTML elements and their attributes. For example, let’s extract all the links on the Wikipedia page:

links = soup.find_all("a")
for link in links:

Step 7: Handling Exceptions:
Web scraping may encounter errors, such as connection issues or missing elements. Implement error handling to ensure a smooth execution:

    # Web scraping code
except Exception as e:
    print("An error occurred:", str(e))

Congratulations! You have successfully learned how to perform web scraping using Python. We covered the installation of necessary libraries, sending HTTP requests, parsing HTML content, extracting data, and handling exceptions. Web scraping opens up a world of possibilities for data extraction and automation. However, remember to be respectful of websites’ terms of service and use web scraping responsibly. Happy scraping!
