发个帖子纪念一下，欢迎大家一起讨论Python

[gashero]

偶比较喜欢Python ，以前Java也看过很多。希望大家一起讨论。
有空可以去我的博客看看(http://blog.csdn.net/gashero)。偶不习惯于转贴，贴一段自己的程序吧。作Socket服务器的。

代码： 全选

# -*- coding: gbk -*-
from socket import *
import time

localip=gethostbyname(gethostname())

def server():
	s=socket(AF_INET,SOCK_STREAM)
	s.bind((localip,5555))
	s.listen(10)
	print 'Server start'
	while True:
		try:
			print 'waiting connect...'
			c,i=s.accept()
			print 'Client (%s,%d)'%i
			data=c.recv(1000)
			while len(data)!=0:
				print data
				data=c.recv(1000)
			print 'Client closed!'
		except KeyboardInterrupt:
			print 'Keyboard Terminate'
			break
	print 'server ending'
	s.close()
	return

def main():
	server()
	return

if __name__=='__main__':
	main()

python的确不错，我帖一段我写的访问MySQL的类库
