this example from a Well House Consultants training course
Source code: udp_server.py Module: Y303
# A UDP server
# Set up a UDP server
UDPSock = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
# Listen on port 21567
# (to all IP addresses on this system)
listen_addr = ("",21567)
# Report on all data packets received and
# where they came from in each case (as this is
# UDP, each may be from a different source and it's
# up to the server to sort this out!)
data,addr = UDPSock.recvfrom(1024)
