"""This object represents an incoming update.
|
|
|
|
Note:
|
|
At most one of the optional parameters can be present in any given update.
|
|
|
|
Attributes:
|
|

|
|

|
|
edited_message (:class:`telegram.Message`): Optional. New version of a message.
|
|
channel_post (:class:`telegram.Message`): Optional. New incoming channel post.
|
|
edited_channel_post (:class:`telegram.Message`): Optional. New version of a channel post.
|
|
inline_query (:class:`telegram.InlineQuery`): Optional. New incoming inline query.
|
|

certain positive number and increase sequentially. This ID becomes especially handy if

correct update sequence, should they get out of order.

|
|
photo, sticker, etc.
