import socket

print "Creating socket...",
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print "done."

print "Looking up port number...",
port = socket.getservbyname('http', 'tcp')
print "done."

print "Connecting to remote host on port %d..." % port,
print "done."

print "Connected from", s.getsockname()
print "Connected to", s.getpeername()

返回结果如下：

Creating socket... done.
Looking up port number... done.
Connecting to remote host on port 80... done.
Connected from ('127.0.0.1', 51475)
Connected to ('116.255.236.107', 80)
