[FIXED] sending a list through UDP

Issue

I'm using socket programming for sending a UDP text message and it's working fine. Here is the code:

send:

import socket
UDP_IP = "10.0.0.2"
UDP_PORT = 5005
MESSAGE = "Hello"
print "UDP target IP:", UDP_IP
print "UDP target port:", UDP_PORT
print "message:", MESSAGE
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))

recv:

import socket

UDP_IP = "10.0.0.2"
UDP_PORT = 5005
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))
while True:
  data, addr = sock.recvfrom(1024)
  print "received message:", data

Now I want to change the message I'm sending to a list. I tried to do this by using pickle. Here is the code:

send:

import socket
import pickle

UDP_IP = "10.0.0.2"
UDP_PORT = 5005
a = []
a.append('H')
a.append('G')
MESSAGE = pickle.dumps(a)
print "UDP target IP:", UDP_IP
print "UDP target port:", UDP_PORT
print "message:", MESSAGE
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))

recv:

import socket
import pickle

UDP_IP = "10.0.0.2"
UDP_PORT = 5005

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))
while True:
  data, addr = sock.recvfrom(1024)
  print "received message:", data
  pickle.loads(data)
  print(data)

But I'm not getting the correct form of the list in the receiver side. Here is the output:

(1p0
S'H'
p1
aS'G'
p2
a.

(1p0
S'H'
p1
aS'G'
p2
a.

what's wrong?

Solution

The problem is solved. The code is working fine, there was a problem because I was printing the data itself not the output of pickle.loads(data), So this code is working fine now:

recv:

import socket
import pickle

UDP_IP = "10.0.0.2"
UDP_PORT = 5005

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))
while True:
  data, addr = sock.recvfrom(1024)
  print "received message:", data
  print(pickle.loads(data))
