    days, remainder = divmod(total_seconds, 86400)
    hours, remainder = divmod(remainder, 3600)
    minutes, seconds = divmod(remainder, 60)

    d = {
        "total_seconds": total_seconds,
        "days": int(days),
        "hours": int(hours),
        "minutes": int(minutes),
        "seconds": int(seconds),
    }

    if d["hours"] == 0:
        datestr = f"{d['minutes']} minutes"
    else:
        datestr = f"{d['hours']} hours {d['minutes']} minutes"

    return datestr

    lotteryround = lottery.current_round()
    prize_pool = lottery.prize_pool()

    draw_date = lottery.draw_date(lotteryround).astimezone()
    drawdate_str = format_datestr(draw_date)

    allocation = lottery.prize_pool_allocation()

    prize_pool_match1 = allocation.get("match_1")
    prize_pool_match2 = allocation.get("match_2")
    prize_pool_match3 = allocation.get("match_3")
    prize_pool_match4 = allocation.get("match_4")

        draw_date_str = draw_date.strftime("%Y-%m-%d %H:%M")

        prize_pool = int(lottery.prize_pool(lotteryround))

        row = [draw_date_str, lotteryround, prize_pool]
