（Python）MySQL数据库身份验证问题

我试图运行下面的代码，将symbols变量的组件添加到名为securities_master的数据库中。我之前发布了此问题，并修复了大量错误，但我仍然收到以下错误：

Traceback (most recent call last):

客户端端点身份验证协议似乎没有与服务器内联。 你能试试下面提到的步骤吗？

请看相关问题

我曾尝试过您的建议，即使用OLD_PASSWORD（）函数将我的密码重置为一个兼容的密码，但遇到了一个语法错误，告诉我检查我版本手册中的语法。原来MySQL 8.0的旧密码（）已被删除…。最后，我使用命令：ALTER USER'root'@'localhost'通过'password'标识为mysql\u native\u password您的回答帮助我找到了正确的方法，谢谢。嘿@Mikey Mike您能解释一下您在哪里键入ALTER USER。。。查询来解决您的问题，是在mysql提示符下，我尝试在那里键入它，但所发生的只是箭头提示符->，我仍然有错误
