Build a chat server and client to work with it.

Original Iron Forger assignment is at https://hackpad.com/Week-6-Chat-Server-Client-rIxE6ZfW1sN.

Status: Not yet working satisfactorily.

Programs: server.py, client.py. These programs require at least Python 3.4.

• The server and each client choose the port over which they communicate at random. The same seed must be supplied:

   python server.py oh_a_seed_here
   python client.py oh_a_seed_here
  

  etc. If no seed is supplied, the programs use a default seed. If the seeds used are not the same, then the client will not be able to contact the server.

• Using Python 3.4's asyncio module and asyncio.streams.StreamReader and asyncio.streams.StreamWriter objects.
• Multiple clients can log into the same server.
• Each client logs in with its own log-in, and a dictionary is populated, login: (StreamReader, StreamWrite).

• Although each client can communicate independently with the single server, they cannot communicate with each other. An effort is made in server2.py, client2.py to allow different clients to communicate by way of the server, but it is not working now. There seem to be two problems:

  • checking constantly for input and printing output whenever it arrives need to be separate somehow, so that they can appear to take place simultaneously;
  • in server2.py and client2.py, for some reason messages did not go to the clients I expected them to go to — they went to the client that originally sent the messages.

• Implement message functionality.
• Handle commands from the client to the server:
  • ?h: list of commands
  • ?u: list of logged-in users
  • q: quit
  • >u[, u2, ...]: message: send message to user(s) u, u2, etc.
