[Twisted-Python] udp

[Black]

Like Carl suggested, I just eschewed Twisted on the client side when  
I did something similar. Here is a simple client that can be used  
with the server I sent earlier.


import socket

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
data = "Data from client"
s.sendto(data, ('localhost', 8000))
data,address = s.recvfrom(1024)
print "received %r from %r" % (data, address)



If you don't want the server to send anything back, you can skip the  
recvfrom() on the client side and the self.transport.write() on the  
server side. Of course, this doesn't include any error handling for  
when the UDP data doesn't actually make it (which, of course, isn't  
guaranteed) - but this is just to illustrate how simple it is.
