Lottery stats

Get stats from the current lottery round.

Code

from datetime import datetime
from pancakeswap_lottery import Lottery


def format_datestr(dt):
    now = datetime.now().astimezone()
    total_seconds = int((dt - now).total_seconds())

    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


def get_lottery_stats():
    lottery = Lottery()

    issue_index = lottery.get_issue_index()
    pool_size = lottery.get_total_amount()

    lottery_date = lottery.get_lottery_date(issue_index)
    drawdate_str = format_datestr(lottery_date)

    allocation = lottery.get_allocation()

    prize_pool_match4 = int(pool_size * allocation.get("1") / 100)
    prize_pool_match3 = int(pool_size * allocation.get("2") / 100)
    prize_pool_match2 = int(pool_size * allocation.get("3") / 100)

    ret_str = "🥞 The CAKE Lottery 🥞"
    ret_str += f"\nRound #{issue_index}"
    ret_str += f"\nDraw in {drawdate_str} ({lottery_date.strftime('%Y-%m-%d %H:%M')})"

    ret_str += "\n\n💰 Pool size"
    ret_str += f"\n{int(pool_size)} CAKE"

    ret_str += "\n\n💵 Prize pool allocation"
    ret_str += f"\nMatch 4: {prize_pool_match4} CAKE"
    ret_str += f"\nMatch 3: {prize_pool_match3} CAKE"
    ret_str += f"\nMatch 2: {prize_pool_match2} CAKE"

    return ret_str


lottery_stats = get_lottery_stats()

        lottery_date_str = lottery_date.strftime("%Y-%m-%d %H:%M")

        total_rewards = int(lottery.get_total_rewards(issue_index))

        row = [lottery_date_str, issue_index, total_rewards]
        rows.append(row)

    ret_str = "🥞 The CAKE Lottery - History 🥞\n\n"
