Python UDPSocket

from socket import *
from time import ctime
BUFFSIZE = 1024
HOST = "127.0.0.1"
PORT = 10055
ADDR = (HOST, PORT)
mySocket = socket(AF_INET, SOCK_DGRAM, 0)
mySocket.bind(ADDR)
while True:
    print("waiting for message...\n")
    data, addr = mySocket.recvfrom(BUFFSIZE)
    data = data.decode()
    print("connection from ", data)
    if not data:
        break
    mySocket.sendto(("[%s] %s" % (ctime(), data)).encode(), addr)
mySocket.close()
