Python网络编程起步(Socket发送消息)

一、服务端(Server.py)
服务端要做的事情是：
1. 创建一个Socket对象

-->import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) 2. 绑定一个端口

-->s.bind(("", 8081)) 3. 接受来自客户端的消息

-->while True:
# Receive up to 1,024 bytes in a datagram
data, addr = s.recvfrom(1024)
print "Received:", data, "from", addr二、客户端(Client.py)
客户端要做的事情是：
1. 创建一个Socket对象。

-->import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) 2. 向某个服务器的指定的端口发送消息。由于使用UDP，如果服务器端未接收到将会丢弃数据包。

-->port = 8081
host = "localhost"
while True:
msg = raw_input()
s.sendto(msg, (host, port))三、运行试试
