    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 query identifier.
        from_user (:class:`telegram.User`): User who sent the query.
        currency (:obj:`str`): Three-letter ISO 4217 currency code.
        total_amount (:obj:`int`): Total price in the smallest units of the currency (integer, not
            float/double). For example, for a price of US$ 1.45 pass ``amount = 145``.
            See the :obj:`exp` parameter in
            `currencies.json <https://core.telegram.org/bots/payments/currencies.json>`_,
            it shows the number of digits past the decimal point for each currency
            (2 for the majority of currencies).
        invoice_payload (:obj:`str`): Bot specified invoice payload.
        shipping_option_id (:obj:`str`, optional): Identifier of the shipping option chosen by the
            user.
        order_info (:class:`telegram.OrderInfo`, optional): Order info provided by the user.
        bot (:class:`telegram.Bot`, optional): The Bot to use for instance methods.
        **kwargs (:obj:`dict`): Arbitrary keyword arguments.

        id (:obj:`str`): Unique query identifier.
        from_user (:class:`telegram.User`): User who sent the query.
        currency (:obj:`str`): Three-letter ISO 4217 currency code.
