[issue45351] List all sockets in TCP echo server using streams

[Olaf van der Spek]

Olaf van der Spek  added the comment:

> server = await asyncio.start_server(handle_echo, '127.0.0.1', )

If 127.0.0.1 is replaced by localhost, the server might listen on ::1 and 
127.0.0.1 but only one address will be printed, which is confusing (and wrong 
IMO).

So the output of the example isn't wrong if you don't change it, but the 
example code itself could be better.

I'm not clear why you're suggesting this change. Is this additional 
functionality, or is the current example broken? Is the text wrong, or just the 
code?

New submission from Olaf van der Spek :

Replace:
addr = server.sockets[0].getsockname()
print(f'Serving on {addr}')

By:
for socket in server.sockets: 
  addr = socket.getsockname()
  print(f'Serving on {addr}')
