import time

sk = socket.socket()

sk.bind(('192.168.3.12',30031))
sk.listen()

    msg_byte = conn.recv(1024)
    msg_str = msg_byte.decode("utf-8")
    print("客户端:",addr,msg_str)

    #客户端关闭一个
    if msg_str=='bye':

客户端:

import socket

sk.connect(('192.168.3.12',30031))
#print(k,v)
while True:
    input_str = input("我:")
    sk.send(input_str.encode('utf-8'))
    if input_str == 'bye':
        break
    data = sk.recv(1024)
    print("服务器:",data.decode('utf-8'))

sk.close()
