How to get owner_id value in attachments?

Question

Python

Hello, I don't know how to get different owner_id, id, album_id, etc. values. when sending a photo to the bot.
Here is a part of the code from the bot for VK in Python

if event.type == VkBotEventType.MESSAGE_NEW:
            peer_id = event.object.peer_id
            message = event.object.text
            body = event.object.text.lower()
            chat_id = event.chat_id
            user_id = event.object.from_id
            user_attachments = event.object.attachments
            print("Текст сообщения: " + str(message))
            print("Отправлено от: " + str(peer_id))
            print("Вложение: " + user_attachments)
            print("---------------------------------------")

I get this answer
