创建socket,socket.AF_INET表示ipv4地址族,socket.SOCK_STREAM表示TCP协议;使用with as语句就可以不用自己再写s.close()了; bind:绑定ip和端口,127.0.0.1是本机ip,端口号范围0~65535,绑定的端口最好大于1024; listen:服务器接收连接请求,成为正在监听的套接字,参数backlog表示最大监听的个数,python3.5之后取默认...

Socket programming involves connecting to remote machines on LAN or over the internet using ip addresses and port number. For example google.com has an ip "173.194.36.3" and runs http server on port 80. So a socket application can connect to that ip address on that particular port number ...
