客户端程序代码：

# Client programfrom socket import *# Set the socket parametershost = "localhost"port = 21567buf = 1024addr = (host,port)# Create socketUDPSock = socket(AF_INET,SOCK_DGRAM)def_msg = "===Enter message to send to server===";print "/n",def_msg# Send messageswhile (1):data = raw_input('>> ')if not data:breakelse:if(UDPSock.sendto(data,addr)):print "Sending message '",data,"'....."# Close socketUDPSock.close()

 

服务器端程序代码：

# Server programfrom socket import *# Set the socket parametershost = "localhost"port = 21567buf = 1024addr = (host,port)# Create socket and bind to addressUDPSock = socket(AF_INET,SOCK_DGRAM)UDPSock.bind(addr)# Receive messageswhile 1:data,addr = UDPSock.recvfrom(buf)if not data:print "Client has exited!"breakelse:print "/nReceived message '", data,"'"# Close socketUDPSock.close()
