    This object represents an incoming inline query. When the user sends an empty query, your bot
    could return some default or trending results.

    Note:
        * In Python `from` is a reserved word, use `from_user` instead.

    Attributes:
        id (:obj:`str`): Unique identifier for this query.
        from_user (:class:`telegram.User`): Sender.
        location (:class:`telegram.Location`): Optional. Sender location, only for bots that
            request user location.
        query (:obj:`str`): Text of the query (up to 512 characters).
        offset (:obj:`str`): Offset of the results to be returned, can be controlled by the bot.

    Args:
        id (:obj:`str`): Unique identifier for this query.
        from_user (:class:`telegram.User`): Sender.
        location (:class:`telegram.Location`, optional): Sender location, only for bots that
            request user location.
        query (:obj:`str`): Text of the query (up to 512 characters).
        offset (:obj:`str`): Offset of the results to be returned, can be controlled by the bot.
        bot (:class:`telegram.Bot`, optional): The Bot to use for instance methods.
        **kwargs (:obj:`dict`): Arbitrary keyword arguments.

            cache_time (:obj:`int`, optional): The maximum amount of time in seconds that the
                result of the inline query may be cached on the server. Defaults to 300.
            is_personal (:obj:`bool`, optional): Pass True, if results may be cached on the server
                side only for the user that sent the query. By default, results may be returned to
                any user who sends the same query.
            next_offset (:obj:`str`, optional): Pass the offset that a client should send in the
                next query with the same text to receive more results. Pass an empty string if
                there are no more results or if you don't support pagination. Offset length can't
                exceed 64 bytes.
            switch_pm_text (:obj:`str`, optional): If passed, clients will display a button with
                specified text that switches the user to a private chat with the bot and sends the
                bot a start message with the parameter switch_pm_parameter.
            switch_pm_parameter (:obj:`str`, optional): Deep-linking parameter for the /start
                message sent to the bot when user presses the switch button. 1-64 characters,
                only A-Z, a-z, 0-9, _ and - are allowed.
