Answer by Ben Gagnon for socket.recv is empty but the result is showing in Maya

I got it to work by setting up a client socket connection from Maya to PyCharm making a python socket server and setting up maya as the client and using the pickle module to send a list.

Python Server

import socket
import pickle

HOST = 'localhost'
PORT = 50007
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(1)
conn, addr = s.accept()
print 'Connected by', addr
while 1:
    data = conn.recv(4096)
    if not data: break
    conn.send(data)
    data2 = pickle.loads(data)
    print 'servo_1 = %s' % (data2)
conn.close()

Maya Client

import socket, pickle
import maya.cmds as cmds

HOST = 'localhost'
PORT = 50007
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))

max = int(cmds.playbackOptions( q=True, aet=True))
servo_1 = [cmds.getAttr("joint2.rotateY")]

data_string = pickle.dumps(servo_1)
s.send(data_string)

data = s.recv(4096)
data_arr = pickle.loads(data)
s.close()
print 'Received', repr(data_arr)
