i find solution for that error

if i change request to :

if 'nums' in request.POST:
    nums = request.POST['nums']
else:
    nums = False



now i have else error and i think the code in my html form is wrong (inside 
the form i copy paste {% csrf_token %}) and again nothing

Forbidden (403)

CSRF verification failed. Request aborted
Help

Reason given for failure:

    CSRF token missing or incorrect.
    

In general, this can occur when there is a genuine Cross Site Request 
Forgery, or when Django's CSRF mechanism 
<https://docs.djangoproject.com/en/1.8/ref/csrf/> has not been used 
correctly. For POST forms, you need to ensure:

   - Your browser is accepting cookies.
   - The view function passes a request to the template's render 
   
<https://docs.djangoproject.com/en/dev/topics/templates/#django.template.backends.base.Template.render>
 
   method.
   - In the template, there is a {% csrf_token %} template tag inside each 
   POST form that targets an internal URL.
   - If you are not using CsrfViewMiddleware, then you must use csrf_protect 
   on any views that use the csrf_token template tag, as well as those that 
   accept the POST data.

You're seeing the help section of this page because you have DEBUG = True 
in your Django settings file. Change that to False, and only the initial 
error message will be displayed. 

You can customize this page using the CSRF_FAILURE_VIEW setting.
