from import BaseCommand, CommandError
from polls.models import Question as Poll

class Command(BaseCommand):
    help = 'Closes the specified poll for voting'

    def add_arguments(self, parser):
        parser.add_argument('poll_ids', nargs='+', type=int)

    def handle(self, *args, **options):
        for poll_id in options['poll_ids']:
                poll = Poll.objects.get(pk=poll_id)
            except Poll.DoesNotExist:
                raise CommandError('Poll "%s" does not exist' % poll_id)

            poll.opened = False

            self.stdout.write('Successfully closed poll "%s"' % poll_id))

Here is what the above code is Doing:
1. It defines a command, closes the poll, which takes a list of poll IDs as required arguments.
2. It configures the closes the poll command to use the poll_ids argument.
3. It defines a handle() method, which takes the poll IDs and closes the corresponding Poll objects.
4. It outputs a success message to the console for each poll it closes.
