But just can’t quite find my answer. I am trying out a chat script
Server side runs perfectly fine.
# chat_server.py import sys import socket import select HOST = 'localhost' SOCKET_LIST = [] RECV_BUFFER = 4096 PORT = 9009 def chat_server(): server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) server_socket.bind((HOST, PORT)) server_socket.listen(10) # add server socket object to the list of readable connections SOCKET_LIST.append(server_socket) print("Chat server started on port " + str(PORT)) while 1: # get the list sockets which are ready to be read through select # 4th arg, time_out = 0 : poll and never block ready_to_read,ready_to_write,in_error = select.select(SOCKET_LIST,[],[],0) for sock in ready_to_read: # a new connection request recieved if sock == server_socket: sockfd, addr = server_socket.accept() SOCKET_LIST.append(sockfd) print("Client (%s, %s) connected" % addr) broadcast(server_socket, sockfd, "[%s:%s] entered our chatting roomn" % addr) # a message from a client, not a new connection else: # process data recieved from client, try: # receiving data from the socket. data = sock.recv(RECV_BUFFER) if data: # there is something in the socket broadcast(server_socket, sock, "r" + '[' + str(sock.getpeername()) + '] ' + data) else: # remove the socket that's broken if sock in SOCKET_LIST: SOCKET_LIST.remove(sock) # at this stage, no data means probably the connection has been broken broadcast(server_socket, sock, "Client (%s, %s) is offlinen" % addr) # exception except: broadcast(server_socket, sock, "Client (%s, %s) is offlinen" % addr) continue server_socket.close() # broadcast chat messages to all connected clients def broadcast (server_socket, sock, message): for socket in SOCKET_LIST: # send the message only to peer if socket != server_socket and socket != sock : try : socket.send(message) except : # broken socket connection socket.close() # broken socket, remove it if socket in SOCKET_LIST: SOCKET_LIST.remove(socket) if __name__ == "__main__": sys.exit(chat_server())
But client
import sys import socket import select def chat_client(): host = "127.0.0.1" port = 9009 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.settimeout(2) # connect to remote host try : s.connect((host, port)) except : print('Unable to connect') sys.exit() print('Connected to remote host. You can start sending messages') sys.stdout.write('[Me] '); sys.stdout.flush() while 1: socket_list = [sys.stdin, s] potential_errs=[] # Get the list sockets which are readable ready_to_read,ready_to_write, in_error = select.select(socket_list , host, int(1)) for sock in ready_to_read: if sock == s: # incoming message from remote server, s data = sock.recv(4096) if not data : print('nDisconnected from chat server') sys.exit() else : #print data sys.stdout.write(data) sys.stdout.write('[Me] '); sys.stdout.flush() else : # user entered a message msg = sys.stdin.readline() s.send(msg) sys.stdout.write('[Me] '); sys.stdout.flush() if __name__ == "__main__": sys.exit(chat_client())
Has run from cmd, not IDLE because of issues (read something about it relating to my issue)
Traceback
line 50 in module sys.exit(chat_client()) line 28 in chat_client ready_to_read,ready_to_write, in_error = select.select(socket_list , host, int(1)) TypeError: argument must be an int or have a fileno() method

Answer
select
doesn’t work with non-socket objects on Windows. For more information see the documentation about select.select, where it mentions that:
File objects on Windows are not acceptable, but sockets are. On Windows, the underlying
select()
function is provided by the WinSock library, and does not handle file descriptors that don’t originate from WinSock.
