Client - Server Programs in Python

In this project, you need to replicate the echo client and server program and then you are required to enhance the ECHO client/server program. Choose either TCP or UDP version of the echo server/client, modify it to accomplish the following function: • Server side program should accept a parameter as the port number that it will listen on for incoming request, if no parameter is provided, then 9999 is used by default. • User(e.g. me) runs the client program to connect to server. Client program should accept two parameters that allow user to specify the server address and port number. • The client program reads a sentence typed in by user via keyboard, and user can select a command, then it sends both the command and the sentence to the server. • Upon receipt of the sentence and command, server converts all the letters in the sentence into uppercase letters or lower letters or other format based on the received command, and sends the result back to the client. • Client program displays the replied sentence on the screen. Your server should support at least three commands: all uppercase, all lowercase, and another commands that you designed(something like initial caps, reverse each word, reverse the entire sentence, etc.). Include a README document for instructions on how to run your program. You also need to provide a document describing your protocol, i.e., underlying transport layer service, port numbers, the order and format of message sent and received by client/server, action associated with each message, etc. The document should provide enough information for others to implement client and server program to interact with yours.
