Try this:

client:
-------
import socket

s = socket.socket()
host = 'localhost'
port = 3030
s.connect( (host, port) )

arr = [1, 2, 3]

for elmt in arr:
    send_str = "%s," % str(elmt)

    while send_str:
       chars_sent = s.send(send_str)
       send_str = send_str[chars_sent:]

s.close()



server:
-------
import socket

s = socket.socket()

host = "localhost"
port = 3030
s.bind((host, port))

s.listen(5)

while("Ctrl-C hasn't been entered"):
    new_sock, addr = s.accept()
    data_list = []

    while True:
        partial_data = new_sock.recv(1012)
        data_list.append(partial_data)
        if not partial_data: #then got all the data
            break

    data_str = ''.join(data_list)[:-1]  #chop off trailing comma
    arr_strs = data_str.split(",")

    arr_ints = [int(elmt) for elmt in arr_strs]
    print arr_ints
