我使用的是 python 3.9.1、discord 1.0.1、discord.py 1.6.0、dnspython 2.1.0 和 pymongo 3.11.3 我正在尝试制作一个自定义的 Discord 机器人，这是该机器人的模块之一，我现在被这个错误困住了大约 3 天，所以我真的很想从你们那里得到任何提示：D

Answer 1

我认为答案是 leveling 是您分配了 2 个值的一个变量。这使它成为一个元组。因此，当您尝试在元组上运行 find_one 时，它不能，因为它不是您想要的对象。

旁注：如果你创建一个方法 return value1, value2，也会发生类似的事情。在 python 中，这被认为是一个元组。
