一个简单的CS通信的例子（只实现功能，没有考虑异常处理、断开连接等问题）：

# server.py
import socket, threading
def send(socket):
    while True:
        sendmsg = input()
        socket.send(sendmsg.encode())

def receive(socket, addr):
    while True:
        b = socket.recv(1024)
        msg = b.decode()
        print('来自客户端%s:%d的消息：%s' % (addr[0],addr[1],msg))

try:
    sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sk.bind(('127.0.0.1',9999))
    sk.listen(1)
    print('服务器已启动，最多允许1个连接')
    sk_client, addr = sk.accept()
    print(type(addr))
    print('来自%s:%d的新连接！说点什么吧：' % (addr[0], addr[1]))
    tsend = threading.Thread(target=send, args=(sk_client,))
    trecv = threading.Thread(target=receive, args=(sk_client,addr))
    tsend.start()
    trecv.start()
    tsend.join()
    trecv.join()
except socket.error as e:
    print('与客户端的连接出错：%s ' % e)

# client.py
import socket, threading
def send(socket):
    while True:
        sendmsg = input()
        socket.send(sendmsg.encode())

def receive(socket):
    while True:
        b = socket.recv(1024)
        msg = b.decode()
        print('来自服务器的消息：%s' % msg)

try:
    sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    print('尝试连接服务器...')
    sk.connect(('127.0.0.1',9999))
    print('已连接到服务器。说点什么吧！')
    tsend = threading.Thread(target=send, args=(sk,))
    trecv = threading.Thread(target=receive, args=(sk,))
    tsend.start()
    trecv.start()
    tsend.join()
    trecv.join()
except socket.error as e:
    print('无法连接到服务器：%s' % e)
