Python 3 UDP example, with only very minor modifications needed to this guidance: https://wiki.python.org/moin/UdpCommunication

udp-rcv.py

# Simple example that receives UDP messages using Python 3
# Guidance:  https://wiki.python.org/moin/UdpCommunication
import socket

UDP_IP = '127.0.0.1'
UDP_PORT = 5005

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind((UDP_IP, UDP_PORT))

while True:
  print(sock.recv(10240))

udp-send.py

# Simple example that sends UDP message using Python 3
# Guidance:  https://wiki.python.org/moin/UdpCommunication
import socket

UDP_IP = '127.0.0.1'
UDP_PORT = 5005
MESSAGE = b'Hello, UDP!'

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))
