多线程套接字服务器python

服务器：

import socket
import threading
import sys

sock = socket.socket()
sock.bind(('192.168.0.100', 1080))
sock.listen(3)
conn = []

def Reciver():
    while 1:
        for i in range(len(conn)):
            try:
                data = conn[i].recv(1024)
                if data:
                    print(data.decode())
            except socket.error as e:
                if e.errno == 10053:
                    conn.pop(i)
                    print("Подключено пользователй:", len(conn))
                else:
                    raise

def Sender():
    while 1:
        global conn
        message = input()
        if message:
            for i in range(len(conn)):
                conn[i].send(message.encode())

def Accepter():
    while 1:
        global conn
        conn.append(sock.accept()[0])
        print("Подключено пользователй:", len(conn))


# init threads
t1 = threading.Thread(target=Reciver)
t2 = threading.Thread(target=Sender)
t3 = threading.Thread(target=Accepter)

# start threads
t1.start()
t2.start()
t3.start()

客户端代码：

import socket
import threading
import sys

host = "192.168.0.100"
port = 1080
sock = socket.socket()
sock.connect((host, port))

def Reciver():
    while 1:
        data = sock.recv(1024)
        if data:
            print(data.decode())

def Sender():
    while 1:
        message = input()
        if message == "exit":
            sock.close()
            sys.exit()
        else:
            sock.send(message.encode())

# init threads
t1 = threading.Thread(target=Reciver)
t2 = threading.Thread(target=Sender)

# start threads
t1.start()
t2.start()

问题：当连接2个客户端时，发现只有服务端能正常写入，客户端传来bug消息。而当client断开的时候，服务端理解了很久，这就是为什么在断开2的时候，立马出现bug，只断开1，就产生了错误，之后发送消息无论是在服务端还是在服务端都不起作用在客户端..
