如创建socket失败,会抛出socket.error异常,可用except进行捕获 socket.gethostbyname(),可以根据名字获取远程主机的IP: 1#!/usr/bin/python2importsocket3importsys4host='www.baidu.com'5port=806#s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)7try:8remote_ip=socket.gethostbyname(host)9exceptsocket....
Let’s build a socket application using Python. Python provides a native socket class (socket module), so developers don’t need to depend on external libraries. Begin by setting up the Python socket programming client and server: Import socket in Python Example of socket import: Create the fi...
Here is my server code: Code: #shell_server.py for python3 import socket import subprocess s= socket.socket(socket.AF_INET,socket.SOCK_STREAM) #s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.bind(("0.0.0.0",444)) s.listen(1) while True: connexion, client_address = s.ac...
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...
#server.pyimport socket import time # create a socket object serversocket = socket.socket( socket.AF_INET, socket.SOCK_STREAM) # get local machine name host = socket.gethostname() port = 9999 # bind to the port serversocket.bind((host, port)) ...

In the next example code, you’ll see the Python TCP client module code to communicate with the TCP server. Python-TCP-Client.py import socket host_ip, server_port = "127.0.0.1", 9999 data = " Hello how are you?\n" # Initialize a TCP client socket using SOCK_STREAM ...

1. What must happen before you can successfully run a client using Python? Start the server Run the UDP methods Close the socket Run gethostname() 2. Which statement connects to the following host and port? s = socket.socket() host = socket.gethostname() port = 80 s.co...
