Sockets[edit]

Python can also communicate via sockets.

Connecting to a server[edit]

This simple Python program will fetch a 4096 byte HTTP response from Google:

import socket, sys
sock = socket.socket ( socket.AF_INET, socket.SOCK_STREAM )
sock.connect ( ( "google.com", 80 ) )
 
sock.send('GET / HTTP/1.1\r\n')
sock.send('User-agent: Mozilla/5.0 (wikibooks test)\r\n\r\n')
print sock.recv(4096)

High-level interfaces[edit]

Most Python developers will prefer to use a high-level interface over using sockets, such as Twisted and urllib2.
