第一步，最简单的SERVER和CLIENT。感觉和写JAVA,C的最简单的一样一样的，，看来，我只会最简单的？：）

server.py及client.py

#Pserver
import socket

HOST = ‘‘
PORT = 8088

reply = ‘Yes‘

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
print ‘Pserver start listen...‘

s.listen(3)

conn, addr = s.accept()
request = conn.recv(1024)

print ‘request is: ‘, request
print ‘Connect by ‘, addr

conn.sendall(reply)

conn.close()

#Pclient
import socket

HOST = ‘127.0.0.1‘
PORT = 8088

request = ‘cat you hear me?‘

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))

s.sendall(request)

reply = s.recv(1024)
print ‘reply is: ‘, reply
s.close()
