from django.contrib.auth.models import User
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger

user_list = User.objects.all()
page = request.GET.get('page', 1)

paginator = Paginator(user_list, 10)
try:
    users = paginator.page(page)
except PageNotAnInteger:
    users = paginator.page(1)
except EmptyPage:
    users = paginator.page(paginator.num_pages)

return render(request, 'core/user_list.html', { 'users': users })

this is how to u can use it.
