class Update(TelegramObject):
    """This object represents an incoming update.

    Objects of this class are comparable in terms of equality. Two objects of this class are
    considered equal, if their :attr:`update_id` is equal.

    Note:
        At most one of the optional parameters can be present in any given update.

    .. seealso:: :wiki:`Your First Bot <Extensions---Your-first-Bot>`

    Args:
        update_id (:obj:`int`): The update's unique identifier. Update identifiers start from a
            certain positive number and increase sequentially. This ID becomes especially handy if
            you're using Webhooks, since it allows you to ignore repeated updates or to restore the
            correct update sequence, should they get out of order. If there are no new updates for
            at least a week, then identifier of the next update will be chosen randomly instead of
            sequentially.
        message (:class:`telegram.Message`, optional): New incoming message of any kind - text,
            photo, sticker, etc.
        edited_message (:class:`telegram.Message`, optional): New version of a message that is
            known to the bot and was edited. This update may at times be triggered by changes to
            message fields that are either unavailable or not actively used by your bot.
        channel_post (:class:`telegram.Message`, optional): New incoming channel post of any kind
            - text, photo, sticker, etc.
        edited_channel_post (:class:`telegram.Message`, optional): New version of a channel post
            that is known to the bot and was edited. This update may at times be triggered by
            changes to message fields that are either unavailable or not actively used by your bot.
        inline_query (:class:`telegram.InlineQuery`, optional): New incoming inline query.
        chosen_inline_result (:class:`telegram.ChosenInlineResult`, optional): The result of an
            inline query that was chosen by a user and sent to their chat partner.
        callback_query (:class:`telegram.CallbackQuery`, optional): New incoming callback query.
        shipping_query (:class:`telegram.ShippingQuery`, optional): New incoming shipping query.
            Only for invoices with flexible price.

            pre-checkout query. Contains full information about checkout.
        poll (:class:`telegram.Poll`, optional): New poll state. Bots receive only updates about

        poll_answer (:class:`telegram.PollAnswer`, optional): A user changed their answer
            in a non-anonymous poll. Bots receive new votes only in polls that were sent
            by the bot itself.
        my_chat_member (:class:`telegram.ChatMemberUpdated`, optional): The bot's chat member
            status was updated in a chat. For private chats, this update is received only when the
            bot is blocked or unblocked by the user.

        chat_member (:class:`telegram.ChatMemberUpdated`, optional): A chat member's status was
            updated in a chat. The bot must be an administrator in the chat and must explicitly

            :paramref:`telegram.ext.Application.run_polling.allowed_updates` to receive these
            updates (see :meth:`telegram.Bot.get_updates`, :meth:`telegram.Bot.set_webhook`,
            :meth:`telegram.ext.Application.run_polling` and
