Socket

小型服务器：

#!/usr/bin/env python
import socket
s = socket.socket()
host = socket.gethostname()
port = 1234
s.bind((host,port))
s.listen(5)
while True:
	c,addr = s.accept()
	print 'Got connection from',addr
	c.send('Thank you for connecting')
	c.close()

#!/usr/bin/env python
import socket
s = socket.socket()
host = socket.gethostname()
port = 1234
s.connect((host,port))
print s.recv(1024)

服务器打印：
