The chat server should allow multiple chat clients to connect to it simultaneously.

When a new chat client joins the server, they should be asked to enter their user name.

Once they have entered their username, they should then be presented with the options to:

$1)$ Create and join a new chat room; OR

$2)$ Join an existing chat room provided from a list of existing chat rooms

Once the client has joined a chat room, any messages that they send to the chat room are forwarded onto other clients in the chat room, prepended with $"[$USERNAME$]>>".$ For instance, if a client's user name is "NetworksNerd", and they send a chat message that says, "How is everyone today?", then the message that should be sent from the server to the other clients in the chat room is "NetworksNerd $>>$ How is everyone today?"

The client should be able to initiate leaving the server and terminate their connection with a special close sequence "CLOSE".

Write your server and client in Python. Include a README so that the TA is able to easily compile and run your code in an Ubuntu Linux environment.

To demonstrate the correct operation of your code, you will use Tshark $($commandline version of Wireshark$)$ to collect a packet capture of at least $2$ clients connecting to the server and interacting with each other via the server and being able to gracefully terminate their connections with the server.
