Question

我正在进行Python培训。但是，我使用的视频使用Python2进行训练。我正在使用Python3，所以我试图将Python2练习转换为Python3。

我已经解决了不同的错误，但是对于这个错误“需要像对象一样的字节，而不是builtin_function_or_method”我无法找到解决方案

我一直在'connection.send（self.data）'行的server.py上得到错误（见图片）。我相信我需要将self.data转换为字节，因为.send需要字节，但我不知道该怎么做。我尝试过在不同领域进行编码，但没有成功。我相信我需要对“connection.send（self.data）”进行编码，但我不知道如何编码。有谁知道我错过了什么？

Client.py 导入套接字

        self.name = name

        return

        print("Self Data ",self.data)
        connection.send(self.data)

        return

main（）的
