  1. To set a WebSocket error code in Python, you can use the websockets library. The close() method allows you to specify a WebSocket close code and an optional reason for closing the connection.

    Example: Setting a WebSocket Error Code

    import asyncio
    import websockets

    async def handler(websocket, path):
    try:
    async for message in websocket:
    print(f"Received: {message}")
    # Simulate an error and close the connection with a specific error code
    await websocket.close(code=1011, reason="Internal server error")
    except websockets.exceptions.ConnectionClosedError as e:
    print(f"Connection closed with error: {e.code} - {e.reason}")

    async def main():
    server = await websockets.serve(handler, "localhost", 8765)
    print("WebSocket server started on ws://localhost:8765")
    await server.wait_closed()

    asyncio.run(main())
