page() missing 1 required positional argument: 'number' in django

So, I am trying to add pagination to my django website. Here is the code for my view function that handles pagination:

def index(request):
    object_list = Post.published.all()
    latest_post = object_list.last()
    paginator = Paginator(object_list, 3)
    page = request.GET.get('page')
    try:
        posts = Paginator.page(page)
    except PageNotAnInteger:
        posts = paginator.page(1)
    except EmptyPage:
        posts = paginator.page(paginator.num_pages)

    return render(request, 'blog/index.html',{
        'posts':posts,
        'latest_post':latest_post,
        'page':page,
        })

I am getting an error on line 11, inside the try block. Where is the error?

request.GET.get('page') returns None and thus it fails in the next line because page number is required. It's better to use Pagination this way:

paginator = Paginator(object_list, 3)
page = request.GET.get('page')
posts = paginator.get_page(page)

get_page() method handles this case and it will return page 1 in case it's None. Here is the line in the source code where this happens.
