 All types are defined in types.py. They are all completely in line with the [Telegram API's definition of the types](https://core.telegram.org/bots/api#available-types), except for the Message's `from` field, which is renamed to `from_user` (because `from` is a Python reserved token). Thus, attributes such as `message_id` can be accessed directly with `message.message_id`. Note that `message.chat` can be either an instance of `User` or `GroupChat` (see [How can I distinguish a User and a GroupChat in message.chat?](#how-can-i-distinguish-a-user-and-a-groupchat-in-messagechat)).
 
 The Message object also has a `content_type`attribute, which defines the type of the Message. `content_type` can be one of the following strings:
-`text`, `audio`, `document`, `photo`, `sticker`, `video`, `voice`, `location`, `contact`, `new_chat_member`, `left_chat_member`, `new_chat_title`, `new_chat_photo`, `delete_chat_photo`, `group_chat_created`, `supergroup_chat_created`, `channel_chat_created`, `migrate_to_chat_id`, `migrate_from_chat_id`, `pinned_message`.
