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

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

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

    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 256 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.

    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 256 characters).
        offset (:obj:`str`): Offset of the results to be returned, can be controlled by the bot.
