本文提供了一个Python实现的TCP Socket通信示例，包括服务器端和客户端的代码。服务器监听本地9527端口，客户端发送消息并接收服务器响应。

套接字相关的系统调用：
socket(): 创建一个套接字
bind()：绑定IP和端口
listen()：监听
accept()：接收请求
connect()：请求连接建立
write()：发送
read()：接收
close():关闭连接

socket通信示例：

服务器端tcpserver.py

#/usr/bin/python
import socket
HOST='127.0.0.1'
PORT=9527
BUFFER=4096
sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
sock.bind((HOST,PORT))
sock.listen(3)
print('tcpServer listen at: %s:%s\n\r' %(HOST,PORT))
while True:
client_sock,client_addr=sock.accept()
print('%s:%s connect' %client_addr)
while True:
recv=client_sock.recv(BUFFER)
if not recv:
client_sock.close()
break
print('[Client %s:%s said]:%s' %(client_addr[0],client_addr[1],recv))
client_sock.send('tcpServer has received your message')
sock.close()

客户端tcpclient

#/usr/bin/python
import socket
HOST='127.0.0.1'
PORT=9527
BUFFER=4096
sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
sock.connect((HOST,PORT))
sock.send('hello, tcpServer!')
recv=sock.recv(BUFFER)
print('[tcpServer said]: %s' % recv)
sock.close()

执行下面命令测试
python tcpserver
phthon tcpclient
