Web scraping is the process of extracting data from websites. In this guide, we'll explore how to implement web scraping in a Flask web application. You'll learn how to use popular Python libraries like BeautifulSoup and Requests to scrape data from websites and display it on your Flask application. By following this guide, you'll have the knowledge and tools to gather and display web data in your web application.

Step 1: Setting Up Your Flask Application

Start by setting up your Flask application and creating a directory structure. Here's a sample structure:


Step 2: Installing Flask, Requests, and BeautifulSoup

Install Flask, Requests, and BeautifulSoup using pip:

pip install Flask
pip install requests
pip install beautifulsoup4

Step 3: Creating the Flask Application

Create your Flask application. Here's an example of Python code:

from flask import Flask, render_template
import requests
from bs4 import BeautifulSoup
app = Flask(__name__)
def index():
url = '' # Replace with the URL you want to scrape
page = requests.get(url)
soup = BeautifulSoup(page.content, 'html.parser') # Extract and display data from the website
data = soup.find_all('p') # Example: extracting all paragraph elements
return render_template('index.html', data=data)
if __name__ == '__main__':

Step 4: Creating HTML Templates

Create an HTML template to display the scraped data. Here's an example of an index template:

<!-- templates/index.html -->
<!DOCTYPE html>
<title>Web Scraping App</title>
<h1>Web Scraping App</h1>
{% for item in data %}
<li>{{ item.get_text() }}</li>
{% endfor %}


Implementing web scraping in your Flask application allows you to collect and display data from websites. By following this guide, you've learned how to set up your Flask application, use Python libraries like Requests and BeautifulSoup, and extract data from websites. You can expand on this knowledge to create more advanced web scraping applications with features like data cleaning and transformation.
