Receive data from a Simulink's built-in "UDP Send" block in python

 import sys, struct  
 import time  
 from socket import *  
 SIZE = 1024   # packet size  
 hostName = gethostbyname('0.0.0.0')  
 mySocket = socket(AF_INET,SOCK_DGRAM)  
 mySocket.bind((hostName,18726))  
 repeat = True  
 while repeat:  
   (data,addr) = mySocket.recvfrom(SIZE)  
   data = struct.unpack('d',data)  
   print int(data[0])
