TypeError: get_members() takes 2 positional arguments but 3 were given (I actually gave 2)

Question

我正在制作一个机器人，它有一个名为 get_members() 的方法，它需要 2 个参数 self and client。我提供了两个参数，但它仍然说我提供了 3 个参数。

客户端参数也显示警告意外参数

堆栈跟踪

    self.scraped = self.get_members(self, client)

During handling of the above exception, another exception occurred:

Answer 1

self不能被你通过。它由 Python.

隐式传递

self.get_members(client)

Answer 2

你必须删除第一个参数self，因为get_members已经是一个方法，self它已经在你调用它时隐式传递，所以你需要做： self.get_members(client)

Answer 3

你在调用方法时传递了self参数，python已经确认了self参数，你不需要再次传递，所以你的代码应该是：

self.scraped = self.get_members(client)

如果您的客户端在您的 class 中，您需要将 self 参数传递给您的客户端。所以你的代码将是：

self.scraped = self.get_members(self.client)
