    def get(self, request, *args, **kwargs):

        the_form = SubmitUrlForm()

        context = {

            "title": "Kirr.co",

            "form": form

        }

        template = "shortener/home.html"

        if form.is_valid():

            new_url = form.cleaned_data.get("url")

            obj, created = KirrURL.objects.get_or_create(url=new_url)

            context = {

                "object": obj,

                "created": created,

            }

            if created:

                template = "shortener/success.html"

            else:

                template = "shortener/already-exists.html"

        return render(request, template ,context)

The question is, what is the purpose of get method here,when we have post method

is it useless in this case?If not what is function of get method?

Why would it be useless? The get method is for GET requests, the post method is for POST requests.

Assuming this view is for a path like

http://example.com/shortener

If you make a GET request to it (as in navigating to it in a browser)
it displays the form calling the "get" method in the view. When you
submit the form it usually does so to the same URL but with the POST
method.

So in this case, GET => Displays form, POST => Handles form submission
