Why VK bot replies 2 times?

Question

Python

There is such a code

def write_messages(sender, message):
      authorize.method('messages.send', {'chat_id': sender, 'message': message, 'random_id': get_random_id(), 'attachment': ','.join(attachments)})
def write_messages_us(user_id, message):
      authorize.method('messages.send', {'peer_id': user_id, 'message': message, 'random_id': get_random_id(), 'attachment': ','.join(attachments)})
users = [id пользователя, id второго пользователя]
for id in users:
            user_id=id
            if id == 'id пользователя':
              try:
                write_messages_us(id, (re.sub(r'!Рассылка', " ", reseived_message)))
              except Exception as ex:
                print("Ошибка")
            else:
              write_messages(sender, "А у тебя нет прав на эту команду")

When a person who is allowed to make a mailout (!Mailout) then everything is fine, but when a person who is forbidden to do it writes the command!Mailout, then the bot answers TWO times this: "But you do not have rights to this command." Why does he say this twice and how to fix it?

Answer 1

I managed to fix it like this:

def write_messages(sender, message):
      authorize.method('messages.send', {'chat_id': sender, 'message': message, 'random_id': get_random_id(), 'attachment': ','.join(attachments)})
    def write_messages_us(id, message):
      authorize.method('messages.send', {'peer_id': id, 'message': message, 'random_id': get_random_id(), 'attachment': ','.join(attachments)})

elif re.findall('!Рассылка', reseived_message):
          if event.object.message['from_id'] in admins:
            for id in users:
              try:
                write_messages_us(id, (re.sub(r'!Рассылка', " ", reseived_message)))
              except Exception as ex:
                print("Ошибка")
          else:
            write_messages(sender, "У вас нет прав")

Answer 2

users = [id пользователя, id второго пользователя]
for id in users:

how many times is it performed?

write_messages(sender, "А у тебя нет прав на эту команду")

so many times the sender comes
