Select of connections

[Gupi]

I've tried to change my server socket's code to something like this...

import socket as skt
import select as sel

IP = "127.0.0.1"
PORT = 9876

server_socket = skt.socket(skt.AF_INET, skt.SOCK_STREAM)
server_socket.setsockopt(skt.SOL_SOCKET, skt.SO_REUSEADDR, 1)
server_socket.bind((IP, PORT))
server_socket.listen()

sockets_list = [server_socket]
clients = {}

print("Listening for connections on {}:{}".format(IP, PORT))


def receive_message(client_socket):
    try:
        message = client_socket.recv(1024)

        if not len(message):
            print("FALSE!")
            return False

        #return message.decode("utf-8")
        print(message.decode())
        return message.decode()

    except:
        return False


while True:
    read_sockets, _, exception_sockets = sel.select(sockets_list, {}, sockets_list)

    for notified_socket in read_sockets:
        #print(notified_socket)
        if notified_socket == server_socket:
            client_socket, client_address = server_socket.accept()
            message = receive_message(client_socket)
            print("Pre-Connected!")
            if message is False:
                continue
            sockets_list.append(client_socket)
            print("Connected!")

        else:
            message = receive_message(notified_socket)

            if message is False:
                print('Connection is closed...')
                sockets_list.remove(notified_socket)
                continue

            print(message + "123")

    for notified_socket in exception_sockets:
        sockets_list.remove(notified_socket)

But when server receives the message, it's automatically receives one more empty message, which makes connection shut down. How can I fix that?
