Fetching the port number using asyncio

[gary]

Below is the code for multisocket server interacting with client. Port Numbers are pre-assigned as 1000 to 4000 for clients
In the client thread function, writer.get_extra_Info does not fetch the port number(ie.. 1000 to 4000) but displays the random number.
Please advice as how to modify the code below to fetch the correct port Number

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

import asyncio   async def client_thread(reader, writer):   while True:    data = (await reader.read(1024))    if data:             msg=data.decode()             addr,port=writer.get_extra_info("peername")             print("Message from", addr,port)             writer.write(data)             await writer.drain()              else:             writer.close()             print("Connection Closed with the client",addr,port)             return         async def start_servers(host, port):  server = await asyncio.start_server(client_thread, host, port)  await server.serve_forever()   def enable_sockets():  try:         host = '10.102.3.16'         port = 1000         sockets_number = 4         loop = asyncio.get_event_loop()         for i in range(sockets_number):             loop.create_task(start_servers(host,port*(i+1)))             print("Connected to Ports:",host,port*(i+1))         loop.run_forever()  except Exception as exc:         print(exc)   enable_sockets()
