get method inside class based view

forms.py

from django import forms

from .validators import validate_url, validate_dot_com

class SubmitUrlForm(forms.Form):

    url = forms.CharField(

            label='', 

            validators=[validate_url],

            widget = forms.TextInput(

                    attrs ={

                        "placeholder": "Long URL",

                        "class": "form-control"

                        }

                )

            )

views.py

class HomeView(View):

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

        the_form = SubmitUrlForm()

        bg_image = 'https://upload.wikimedia.org/wikipedia/commons/0/05/20100726_Kalamitsi_Beach_Ionian_Sea_Lefkada_island_Greece.jpg'

        context = {

            "title": "Kirr.co",

            "form": the_form,

            "bg_image": bg_image

        }

        return render(request, "shortener/home.html", context) # Try Django 1.8 & 1.9 http://joincfe.com/youtube

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

        form = SubmitUrlForm(request.POST)

        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?
