Socket

小型server：

#!/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()

小型客户机：

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

执行server后执行客户机程序：

server打印：

Got connection from (‘127.0.1.1‘, 61625)
Got connection from (‘127.0.1.1‘, 61626)
Got connection from (‘127.0.1.1‘, 61627)
Got connection from (‘127.0.1.1‘, 61628)

Got connection from (‘127.0.1.1‘, 61634)
Got connection from (‘127.0.1.1‘, 61635)
