I need to modify the below code to send a string from client to server, it needs to ask the server to send back the reverse string to the client. For example 1. Client send "12345" to server 2. Server send "54321" back to client. It needs to be written in Python. Thank you!

editable code:

#import socket module from socket import * import sys # In order to terminate the program serverSocket = socket(AF_INET, SOCK_STREAM) #Prepare a sever socket #Fill in start serverHost = '192.168.0.103' serverPort = 6789 serverSocket.bind((serverHost,serverPort)) serverSocket.listen(5) #Fill in end while True: #Establish the connection print('Ready to serve...') connectionSocket, addr = serverSocket.accept() #Fill in start #Fill in end

try: message = connectionSocket.recv(4096) #Fill in start #Fill in end filename = message.split()[1] f = open(filename[1:]) outputdata = f.readlines() #Fill in start #Fill in end #Send one HTTP header line into socket #Fill in start connectionSocket.Send("HTTP/1.1 200 OK Content-Type: text/html ") connectionSocket.Send(" ") #Fill in end #Send the content of the requested file to the client for i in range(0, len(outputdata)): connectionSocket.send(outputdata[i].encode()) connectionSocket.send(" ".encode())

connectionSocket.close() except IOError: #Send response message for file not found #Fill in start connectionSocket.send("HTTP/ 1.1 404 Not Found ") connectionSocket.send("Content-Type: text/html ") connectionSocket.send(" ") connectionSocket.send("
