Willxxx7/MQTT-IoT-Demo ? reverse-engineered prompt

Build me a simple teaching app in Python that walks a student through real time communication in a fun, hands on way.

It should start from one main script, let the user choose between a fancy terminal view or a plain one, then guide them through MQTT, a browser based SSE dashboard, and a WebSocket client and server demo. I want it to feel like a classroom lesson, not just separate scripts, so the app should explain what is happening as it runs and let one demo stay active while the next one starts. Include a small quiz or review section, and a basic security discussion for real time systems.

Make sure the project is easy to run locally with a virtual environment and a single command from the README. If you need current library details, look up the latest docs online. Keep the code clear enough for students to follow, and make the demos feel lively and interactive.
