    if request.GET.get('add20'):
        u = u+1
        my_dictionary = {
            "u" : u,
        }
    if request.GET.get('add21'):

    return render(request, 'blog/IInd_std.html', my_dictionary)

Try changing it to:

request.GET['add20']:

and

request.GET['add21']:

Also, you are re-initializing my_dictionary in your if statements.

Change it to:

my_dictionary["u"] = u

and

my_dictionary["v"] = v
