python to max udpreceive

hello people...

i try to make python and max msp communicate through simple udpsend and receive objects on max..

this is my python script:
##################################
from socket import *

host = "localhost"
port = 20000
buf = 1024
addr = (host, port)

UDPSock = socket(AF_INET,SOCK_DGRAM)

def_msg = "===Enter message to send to server===";
print "n",def_msg

while (1):
    data = raw_input('>> ')
    if not data:
        break
    else:
        if(UDPSock.sendto(data,addr)):
            print "Sending message '",data,"'....."

# Close socket
UDPSock.close()

###################################################

I use this script to send data to udpreceive object in maxmsp...

the problem is that when i run the script from python, maxmsp prints:

net.recv.udp: OSC packet size (1) not a multiple of bytes: dropping

i tried various types of messages and the only thing that changed was the OSC packet size()

Whats the problem here? And why maxmsp reads osc, while i send simple udp messages?

im not very experienced in scripting so its very difficult for me to understand OSC so i try to use simple udp messages...
