I made a website in python using Django. My site allows you to control lights while indicating if the light is on or not. I'm looking for a solution that could make a simple request with data to the server and send data back to the client without updating the entire page but only a part of it.

My ideal would be for the client to make a request to the server with identification data. Then, the server returns the updated data that the user is allowed to have.

Is that possible to make a JavaScript to do that ? And the server, how it can return data to the client ?

You can Use jquery AJAX for send request and get a response and Update an element or part of the page you can read more about it in :

W3schools

or :

jquery.com

AJAX function I use for PHP project:(Just for example)

$.ajax({
        type: "POST",
        url: Url,
        data: InfoData, // data if you want to send for example InfoData={dataName: variable} or you can set this = '' if you don't want to send data
        datatype: "html",
        success: function(result) {
            console.log(result);
        }
    });
