Using PyCharm, I need a function for "client1.py" as well as a function for "server1.py" so that the client can receive and send a message to the servers cipher function following with the server sending back the encrypted message that will then display on the screen of client1.py. Thank you so much in advance, I tried to be as specific as possible!! Will up-vote IMMEDIATELY any correct response!

Please write your own function in the server, which encrypts a message based on Caesar cipher. See the description and implementation of Caesar cipher here: https://www.geeksforgeeks.org/caesar- cipher-in-cryptography. Here is what you need to do: (1) The client receives a message from the user like "Transformers the last knight. Please note that Caesar cipher can only handle letters. (2) The client send the message to the server's Caesar cipher function (3) The server encrypts the message and send it back to the client (4) The client display the encrypted message on the screen
