Why do several photos in one message appear as different messages? And how to receive and send several photos in one message?

Question

Python

Hello!
Please tell me, I want to get the IDs of all the photos and write them to the database, which are sent in one message, for subsequent sending via sendMediaGroup, but for some reason, photos from one message come as several different messages in which there is one photo.
I do it like this:

if message.content_type == "photo":
        photo_id = message.photo[0].file_id
        photos = []
        for i in photo_id:
            photos.append(InputMediaPhoto(photo_id))
            break
        await bot.send_media_group(message.chat.id, photos)

and when I send n photos to the bot in one message, then I receive n messages with each photo in response.

Answer 1

For each photo sent in an album, the key "media_group_id" is returned in the message dictionary, in one album, all documents have the same key
