有没有哪位大佬帮我看下这段代码有什么问题啊
关于网络编程的服务器端和客户端运行后 客户端输入  hi 提示出错
                      TypeError: a bytes-like object is required, not 'str'
应该需要解码吧，怎么解决啊  求助！！！

没写过原生态的网络程序代码
现在写服务器都用现成的轮子，自己造，太累

tcpCliSock.send(('[%s]%s' % (bytes(ctime(),'utf-8'),data)).encode("utf-8"))    服务器端

tcpCliSock.send(data.encode("utf-8"))    客户端
