如何使用 python 在 discord.py 上制作排行榜命令？

Question

I have been trying to write a Discord bot with my friends and I'm trying to make a leaderboard command. I have been trying to fix the command and refilling the numbers, but nothing has worked.

You don't want to sort dict.items() because then you'll be stuck finding the keys. You can use a class definition.

class LeaderBoardPosition:

    def __init__(self, user, coins):
        self.user = user
        self.coins = coins

and use a simple sorting function (this assuming your data is stored in "coins"):

leaderboards = []
for key, value in coins.items():
    leaderboards.append(LeaderBoardPosition(key, value))

top = sorted(leaderboards, key=lambda x: x.coins, reverse=True)

Now you have a list, named top with the data. Here is a simple leaderboard function.

await message.channel.send(f'**<< 1 >>** <@{top[0].user}> with {top[0].coins} coins')
try:
    await message.channel.send(f'**<< 2 >>** <@{top[1].user}> with {top[1].coins} coins')
    try:
        await message.channel.send(f'**<< 3 >>** <@{top[2].user}> with {top[2].coins} coins')
    except IndexError:
        await message.channel.send('There is no 3rd place yet.')
except IndexError:
    await message.channel.send('There is no 2nd place yet.')
