Web Scraping and Data Extraction - Website Change Tracker

 

Notes:

• Problem Solved: Monitors a webpage for any HTML/textual changes over time.

• Customization Benefits: Set up alerts or track competitor website updates.

• Further Adoption: Integrate with Slack/email APIs to send alerts.

Python Code:

import hashlib

import requests

import time

def get_page_hash(url):

    response = requests.get(url)

    return hashlib.sha256(response.text.encode()).hexdigest()

def track_changes(url, interval=60):

    old_hash = get_page_hash(url)

    print("Monitoring started...")

    while True:

        time.sleep(interval)

        new_hash = get_page_hash(url)

        if new_hash != old_hash:

            print("Website content changed!")

            break

        else:

            print("No change detected...")

# Example usage

# track_changes("https://example.com", interval=300)
