Instantly Download or Run the code at https://codegive.com
in this tutorial, we'll create a python script that checks a website for changes. this can be useful for monitoring updates on a website or being notified when specific content changes. we'll use the requests library to fetch the web page and hashlib to calculate a hash of the page content for comparison.
make sure you have python installed on your system. if not, you can download and install it from python's official website.
install the required libraries using the following command:
the get_website_content function uses the requests library to fetch the html content of the specified url.
the calculate_hash function takes the content as input and calculates the sha-256 hash of the content. this hash is used to uniquely identify the content.
in the main function, we specify the url of the website to monitor and initially fetch its content.
the script then enters a loop where it periodically fetches the current content of the website and compares its hash with the initial hash. if the hashes differ, it indicates a change in the website content.
adjust the sleep duration (in seconds) based on how frequently you want to check for changes.
run the script by executing python script_name.py in your terminal, and it will continuously monitor the specified website for changes. adjust the website_url variable to monitor a different website.
