I'm implementing a socket-client which opens several sockets at the same time. Any socket may have data at a different time and I want to execute code when any socket has data and is readable.

I'm not sure how to implement this, I was looking at select.select but it seems to wait for all the sockets to be readable.

I'd like to avoid using multiprocessing to handle data on the sockets, I would like it to be serial in reading from each socket but read when there is data available.

How do I wait for any socket to be readable?

# psudo codesockets = [sock1, sock2, sock3]while True:if len(sockets) == 0:breakfor sock in sockets:if sock.has_data():do_stuff(sock)sockets.remove(sock)sleep(0.1)

You can use select.select for your problem:

sockets = [sock1, sock2, sock3]
while sockets:rlist, _, _ = select.select(sockets, [], [])for sock in rlist:do_stuff(sock)sockets.remove(sock)
