[转] 最简单的使用UDP通信的Python Socket例子
来源：http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/
客户端程序代码：
# Client program
from socket import *
# Set the socket parameters
host = "localhost"
port = 21567
buf = 1024
addr = (host,port)
# Create socket
UDPSock = socket(AF_INET,SOCK_DGRAM)
def_msg = "===Enter message to send to server===";
print "\n",def_msg
# Send messages
while (1):
data = raw_input('>> ')
if not data:
break
else:
if(UDPSock.sendto(data,addr)):
print "Sending message '",data,"'....."
# Close socket
UDPSock.close()
服务器端程序代码：
# Server program
from socket import *
# Set the socket parameters
host = "localhost"
port = 21567
buf = 1024
addr = (host,port)
# Create socket and bind to address
UDPSock = socket(AF_INET,SOCK_DGRAM)
UDPSock.bind(addr)
# Receive messages
while 1:
data,addr = UDPSock.recvfrom(buf)
if not data:
print "Client has exited!"
break
else:
print "\nReceived message '", data,"'"
# Close socket
UDPSock.close()

Python似乎很讨厌修饰符，没有常见的static语法。其静态方法的实现大致有以下两种方法：
第一种方式（staticmethod）：
>>> class Foo:
str = "I'm a static method."
def ba ......

1: os.listdir(path) //path为目录
功能相当于在path目录下执行dir命令，返回为list类型
print os.listdir('..')
输出：
[a,b,c,d]
2: os.path.walk(path,visit,arg)
path ：是将要遍历的目录
visit ：是一个函数指针，函数圆形为：
callback(arg,dir,fileList)
其中arg为� ......
