Python_服务器与多客户端通信、UDP协议、pycharm打印带颜色输出、时间同步的机制

1、服务器与多客户端通信

import socket
# 创建tcp socket的套接字
sk = socket.socket()
# bind
sk.bind(('127.0.0.1',8080))
# 监听
sk.listen(5)
# 等待连接
while 1:
    conn, addr = sk.accept()
    while 1:
        msg_s = input('>>>')
        conn.send(msg_s.encode('utf-8'))
        if msg_s == 'q':
            break
        msg_r = conn.recv(1024).decode('utf-8')
        if msg_r == 'q':
            break
        print(msg_r)
    conn.close()

sk.close()

import socket

sk = socket.socket()

sk.connect(('127.0.0.1',8080))


while 1:
    msg_r = sk.recv(1024).decode('utf-8')
    if msg_r == 'q':
        break
    print(msg_r)
    msg_s = input('>>>')
    sk.send(msg_s.encode('utf-8'))
    if msg_s == 'q':
        break

sk.close()
