2. Project Description UChat is a chat application that allows one single chat server (called UChatServer.py) serves multiple chat clients (called UChatClient.py)simultaneously. In particular, connected clients can: list the members already logged in, log in with a username, exchange messages with other logged in users, and log out. The chat server can accept and maintain connections to all the clients and relay chat messages between them. 2.1 The Chat Client The chat client application has to do the following tasks: 1. Connect to a chat server. The client obtains the server IP address and the port it is listening on from command❝line arguments. For example: > ./UChatClient.py 128.32.48.187 10000 Then, the client immediately attempts to connect to the server socket using TCP. If it fails, the client application prints an error message to the console and returns. To print the error message, the client must give the name of the socket function that failed in lowercase. If, on the other hand, the connection succeeds, the client continues to step 2. 2. Accept console text commands from the user. The client must be able to handle the following commands. Parameters are enclosed in <>: a. login b. list c. sendto d. logout e. exit Each line must begin with a command. The parameters (if any) are separated by a space. The commands and parameters are described in more detail below. In order to implement these commands correctly, thclient will have to send and receive the following messages to/from the server: a. Send messages to the server. The client must be able to send the following messages to the server. These mes
