discord.py 排名系统排行榜

Question

我目前正在尝试为我的 Discord.py 关卡系统制作排行榜，以便您进行！排行榜，然后嵌入位置 1、2、3 等等

Level 和 Exp 存储在一个 Json 中看起来像这样：

{"589898942527963157": {"experience": 25, "level": 2, "LastMessage": 202108011409}, "538477109148909599": {"experience": 0, "level": 0, "LastMessage": 202107312203}}

有没有人知道如何根据最高级别对其进行排序，然后使其进入排名为 1 2 3 等的排行榜。

我的代码现在看起来像这样：

Answer 1

如果你想要一个快速的单行，sorted(x.items(), key=lambda n: n[1]['level'], reverse=True) 就是它，这将返回一个包含元组的列表，按 dict 值的“级别”从高到低排序，调用 dict() 将给出你是排序字典

对代码的一种解释，dict.items() 将返回一个基本上是[(key1, value1), (key2, value2)] 形式的可迭代对象，并且列表的每个元素都被传递给 lambda 函数，该函数接受第二个元素, 外层dict的值，并按它的'level'键排序
