arshadali-coder/classroom-chat ? reverse-engineered prompt

Build me a simple classroom chat app in Python.

I want teachers and students to be able to join a room, see who else is there, and send messages in real time or close to it. It should feel easy to use, with a clean start screen, a way to create or join a classroom room, and a basic room view where messages show up clearly.

If it helps, add a simple room discovery page so people can find available rooms instead of typing everything manually. Keep it lightweight and straightforward, since this is for a classroom setting and should be easy for non technical people to use.

Please wire the pieces together so the app actually runs end to end, and include anything needed to test it quickly. If you need to look up current Python library docs or patterns, go ahead and do that.
