python socket programming [WinError 10038] An operation was attempted on something that is not a socket,I’m currently following a tutorial on python socket programming because I wanna learn how to make a small chat application with python.
https://www.youtube.com/watch?v=3QiPPX-KeSc,Looking back at his code and mine, I don’t see anything I’ve done wrong.
I’ve looked at other questions about this error on here, none of them answer what I’m currently having problems with.,
How can I check that a value exists in a dictionary or not in python

Though upon connecting to the server with my client, I get this error on the server:

Exception in thread Thread-1:

OSError: [WinError 10038] An operation was attempted on something that is not a socket

here is the code for my server:

import socket

print("nPlease input the IP address and port.nInput 0 if you want to resort to the default values")
server = input("IP: ")
port = int(input("Port: "))

if(server=="0"):
    server=socket.gethostbyname(socket.gethostname())
if(port==0):
    port=5050

header = 64
addr = (server, port)
format="utf-8"
disconnm = "!disconnect"
state = ["[starting]", "[connection]"]

sserver = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sserver.bind(addr)

def handle_c(conn, addr):
    print(f"{state[1]} connection from {addr}")

    connected = True
    while connected:
        msg_l = conn.recv(header).decode(format)
        if msg_l:
            msg_l = int(msg_l)
            msg = conn.recv(msg_l).decode(format)
            if msg == disconnm:
                connected = False

            print(f"[{addr}] {msg}")

        conn.close()

def start():
    print("{} server is starting..".format(state[0]))
    sserver.listen()
    print(f"{state[0]} server is listening for connections on {server}:{port}")
    while True:
        conn, addr = sserver.accept()
        thread = threading.Thread(target=handle_c, args=(conn, addr))
        thread.start()
        print(f"{state[1]}, {threading.active_count() - 1}")

start()

client:

import socket

print("nPlease input the IP address and port of the server you want to connect to.")
server = input("IP: ")
port = int(input("Port: "))
addr = (server, port)

header = 64
format="utf-8"

client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(addr)

Answer by Santos Drake

sock = socket.socket()
sock.bind((address, port))
sock.listen(5)
client_sock, client_address = self.sock.accept()

while True:
    data = client_socket.recv(1024)
    msg = 'Server got: ' + data.decode()  
    client_socket.sendall(msg.encode())
    client_socket.close()

		sock = socket.socket()
		sock.connect(server_address)

		sock.sendall(request.encode())
		data = sock.recv(1024)

		while data:
			print(data.decode())
			data = sock.recv(1024)

		sock.close()

I am working on this code

from socket import *
HOST = 'localhost'
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST, PORT)
serversock = socket(AF_INET, SOCK_STREAM)
serversock.bind(ADDR)
serversock.listen(2)

while 1:
    print ("waiting on connection")
    clientsock, addr = serversock.accept()
    print ('connected from:', addr)
    while 1:
        data = clientsock.recv(1024).decode()
        if not data: break 
        clientsock.send(data.encode())
        clientsock.close()

serversock.close()

Answer by Cal Townsend

I was reading up on Python Networking using sockets and found the code below at the end. I have the server file which works fine and starts the server on port 9009.,Also, reading on similar questions I have found out that
sys.stdin is not a socket so that could be why I’m
getting this error. Is there anything I can do to fix this?,Also, reading on similar questions I have found out that sys.stdin is not a socket so that could be why I’m getting this error. Is there anything I can do to fix this?,Note that in this example approach, when one began typing in a line, incoming messages will only be displayed after the input line is finished.

I was reading up on Python Networking using sockets and found the code below at the end. I have the server file which works fine and starts the server on port 9009.

# chat_client.py

        sys.exit()

    port = int(sys.argv[2])

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.settimeout(2)

    # connect to remote host
    try :

                else :

                sys.stdout.write('[Me] '); sys.stdout.flush() 

if __name__ == "__main__":

   sys.exit(chat_client())

However, when I try the client part above, I get:

OSError: [WinError 10038] An operation was attempted on something that is not a socket

The lines where the errors are coming from are:

read_sockets, write_sockets, error_sockets = select.select(socket_list , [], [])

and

sys.exit(chat_client())

Answer by Miles Carter

I created a server/client code to create a chat room using socket programming and multi-threading.I encountered an error that i dont seem to understand The server code is working, but i am facing issues with the client code and idk why it is saying its not a socket. i would appreciate any help on this., Save my name, email, and website in this browser for the next time I comment.

Client code

import socket
import select
import sys
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# if len(sys.argv) != 3:
#     print ("missing arguments enter: <IP address> <port number>")
#     exit()
IP_address="127.0.0.1"
Port = 12000
server.connect((IP_address, Port))
while True:
    # create a list to maintain possible input streams
    sockets_list = [sys.stdin, server]
    """ Two possible inputs scenarios. Either the
    user enters text to send to other clients, or the 
    server is sending a message to the client. """

    """ select system call returns from sockets_list, the stream 
    that is reader for input. So for example, if the server sent a message, then the if condition will hold true below. 
    If the user wants to send a message, the else

    print("wait on select call...")
    read_sockets, write_sockets, error_sockets = select.select(sockets_list,[],[])
    print("select call returned")
    print("read_sockets: ", read_sockets)

    for socks in read_sockets:
        if socks == server:

            if(len(message) != 0):
                print(message)
            # server sent empty message, print error and leave
            else:
