Questions & Answers

Q: How do you create a WebSocket server with Python?

To create a WebSocket server with Python, you need to set up a virtual environment, install the WebSockets package, and define a WebSocket handler to handle incoming connections and messages.

Q: How can you connect to a WebSocket server from a web browser?

You can connect to a WebSocket server from a web browser using the WebSocket API that is built into every browser. You can establish a connection and send/receive messages to communicate with the server.

Q: What is the purpose of the echo server in the tutorial?

The echo server is a simple example that returns the received message back to the client. It demonstrates the basic functionality of a WebSocket server and how messages can be transmitted between the client and server.

Q: How can clients communicate with each other using the WebSocket server?

Clients can communicate with each other using the WebSocket server by implementing functionality to send messages to all connected clients. By maintaining a connected set of WebSocket connections, the server can iterate through the connections and send messages to all clients.
