我目前正在尝试为我的 Discord.py 级别系统制作排行榜，以便您可以做到！排行榜，然后嵌入位置 1、2、3 等
Level 和 Exp 存储在 Json 中，如下所示：
{"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，然后将其放入包含 1 2 3 等位置的排行榜。
我现在的代码是这样的：

答案 0 :(得分：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，按照 dict 值的“级别”从高到低排序，在它上面调用 dict()会给你排序的字典
对代码的一种解释，dict.items() 将返回一个基本上采用 [(key1, value1), (key2, value2)] 形式的可迭代对象，并且列表中的每个元素都被传递到 lambda 函数中，该函数采用第二个元素，外层字典的值，按它的'level'键排序
