的端口扫描工具是在子窗口中运行，但有些问题是如何不工作，当我点击“扫描”我得到“Scanning..None”和它没有做任何事情，任何非常感谢您的帮助，谢谢。与Toplevel小窗口部件和端口扫描工具

学会信任你得到的反馈。在你的情况下，代码打印“扫描...无”。所以，当它（大概）应该是别的东西时，显然有些东西是“无”。找出为什么self.host是None，你可能会解决你的问题
答
这不是真的回答你的问题，但你可能想看看Scapy。 Scapy允许您构建自己的数据包并从网络接口读取原始数据。两者在编写端口扫描器时显然非常有帮助。因此，根据您的需要，您可能希望将您的端口扫描器替换为用Scapy编写的端口扫描器。
