我是靠谱客的博主淡淡保温杯，这篇文章主要介绍python网络编程示例(客户端与服务端)，现在分享给大家，希望可以做个参考。

client客户端

复制代码代码如下:

if __name__ == '__main__':
    import socket
    import os
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.connect(('localhost', 8001))
    import time
    time.sleep(2)
    sock.send('1')
    print sock.recv(1024)

    #os.system('pause')
    #raw_input()
    time.sleep(3)
    sock.close()

server服务端

复制代码代码如下:

if __name__ == '__main__':   
    import socket   
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)   
    sock.bind(('localhost', 8001))   
    sock.listen(5)   
    while True:   
        connection,address = sock.accept()   
        try:   
            connection.settimeout(5)   
            buf = connection.recv(1024)   
            if buf == '1':   
                connection.send('welcome to server!')   
            else:   
                connection.send('please go out!')   
        except socket.timeout:   
            print 'time out'   
        connection.close()
