本文详细介绍了单线程阻塞服务器EchoServer和单线程client的实现过程，包括代码解析、运行原理及实际应用。通过实例演示了如何使用Python实现简单高效的网络通信。

1.EchoServer

单线程阻塞Server

# -*- coding: UTF-8 -*-
from SocketServer import BaseRequestHandler, TCPServer

class EchoHandler(BaseRequestHandler):
    def handle(self):
        print "Got connect from", self.client_address
        while True:
            msg = self.request.recv(8192)
            if not msg:
                break
            print self.client_address, msg
            self.request.send(msg)

if __name__ == "__main__":
    serv = TCPServer(('', 2000), EchoHandler)
    serv.serve_forever()

2.Client

单线程client

# -*- coding: UTF-8 -*-
from socket import socket, AF_INET, SOCK_STREAM

s = socket(AF_INET, SOCK_STREAM)
s.connect(('localhost', 2000))
while True:
    data = raw_input()
    if not data or data == 'exit':
        break
    s.send("%s\r\n" % data)
    data = s.recv(8192)
    if not data:
        break
    print data.strip()
print s.send(b"break")
print s.recv(8192)
s.close()
