Socket Programming (소켓 프로그래밍) 연습#1

UDPClient.py

from socket import * serverName = '~~~.~~~.123.171' serverPort = 12000 while 1:     clientSocket = socket(AF_INET, SOCK_DGRAM)        # this creates socket and SOCK_DGRAM indicates it is UDP connection     message = raw_input('Input lowercase sentence:')     clientSocket.sendto(message, (serverName, serverPort))     modifiedMessage, serverAddress = clientSocket.recvfrom(2048)     print modifiedMessage     clientSocket.close()

UDPServer.py

from socket import * serverPort = 12000            # arbitrarily chosen port number (that is available for use) serverSocket = socket(AF_INET, SOCK_DGRAM)        # this creates socket and SOCK_DGRAM indicates it is UDP connection serverSocket.bind(('', serverPort))                               print "The sever is ready to receive" while 1:                                                                 message, clientAddress = serverSocket.recvfrom(2048)     modifiedMessage = message.upper()     serverSocket.sendto(modifiedMessage, clientAddress)

Open up Command Prompt -> enter 'IDLE'

or

Go to 'Start' -> enter 'IDLE" in search box

to initiate Python GUI 

File -> New FIle

Run -> Run Module

Note that this can run only when the UDP Server is running on the other host!
