Python3: Socket UDP

Client

UDP_PORT = 5005
MESSAGE = b"Hello, World!\n"

print("UDP target IP: %s" % UDP_IP)
print("UDP target port: %s" % UDP_PORT)
print("message: %s" % MESSAGE)

                      socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))
sock.close()

Server

while True:

   data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
   print("received message: %s" % data)
