Running Gunicorn

To run Gunicorn, you need to create a Python WSGI application. This can be done in a separate file, for example app.py, as shown below:

def app(environ, start_response):
    status = '200 OK'
    headers = [('Content-type', 'text/plain')]
    response_body = 'Hello, World!'
    start_response(status, headers)
    return [response_body.encode()]

Next, you can start Gunicorn by running the following command:

gunicorn app:app

This will start Gunicorn and listen on the default port 8000. You can access your application by opening a web browser and navigating to http://localhost:8000.
