Python聊天室IP地址文件处理

Question

请注意，我正在努力构建一个简单的代码，我希望这一行代码本质上是有一个代码，在这个代码中，文件以txt文件的形式处理连接到我的服务器的ip地址

我以前试过这样做，但没有用

#server
import socket
import select
IP = "127.0.0.1"
PORT = 4000
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_socket.bind((IP, PORT))
server_socket.listen()
sockets_list = [server_socket]
HEADER_LENGTH = 7
users = {}
print(f'\nWaiting for Client Connections via {IP}:{PORT}...')



# Handles message receiving
def msg_handling(user_socket):
    try:
        msg_h = user_socket.recv(HEADER_LENGTH)
        if not len(msg_h):
            return False
        msg_l = int(msg_h.decode('utf-8').strip())

        return {'header': msg_h, 'data': user_socket.recv(msg_l)}
    except:
        return False
while True:
    identify_sockets, _, accept_sockets = select.select(sockets_list, [], sockets_list)
    for identified_socket in identify_sockets:
        if identified_socket == server_socket:
            user_socket, user_address = server_socket.accept()
            user = msg_handling(user_socket)
            if user is False:
                continue
            sockets_list.append(user_socket)
            users[user_socket] = user
            print('NEW CONNECTION

                  rom {}:{}, username: {}'.format(*user_address, user['data'].decode('utf-8')))  
        else:
            msg = msg_handling(identified_socket)
            if msg is False:
                print('CLOSED CONNECTION from: {}'.format(users[identified_socket]['data'].decode('utf-8')))
                sockets_list.remove(identified_socket)
                del users[identified_socket]
                continue 
            user = users[identified_socket]
            print(f'Received message from {user["data"].decode("utf-8")}: {msg["data"].decode("utf-8")}')
            for user_socket in users:
                if user_socket != identified_socket:
                    user_socket.send(user['header'] + user['data'] + msg['header'] + msg['data'])
