        except PageNotAnInteger:
            page = 1

        p = Paginator(all_orgs, 2, request=request)

        orgs = p.page(page)  -sharp 
        return render(request, "org_list.html", {
            "all_orgs": orgs,
            "all_citys": all_citys,
            "org_nums": org_nums
        })

what result do you expect? What is the error message actually seen?

according to reason, this mistake should not have occurred. Is it Pycharm"s BUG??
paste the version of Pycharm:
