Python 3.6 在 Socket 编程时出现错误如下
Traceback (most recent call last): File "F:/share/IdeaProjects/test/mypython/test/test10_tcpclient.py", line 17, in <module> sock.send(str) TypeError: a bytes-like object is required, not ‘str‘ Process finished with exit code 1
类型错误，解决方案参考 python执行tcp服务器和客户端
将 Client 端代码改为以下
sock.send(bytes(str,‘utf-8‘))
详情请查看 [Python_7] Python Socket 编程
