Socket Python read bynary data

I am getting information from a socket via UDP.
I do not know how to read, this type of date below is binary, hexadecimal ???
��=~%01.00 EB200318151C0000003s��Z�t|
This is the result of part:
while True:
data, addr = sock.recvfrom(1024)
print "received message:", data
Can someone help, what kind of information is coming, how should I read it?

import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
while True:
data, addr = s.recv(1024)
print "received message:" + data

Connecting Teltonika device with Python over TCP

I'm trying to connect with Teltonika device (FMB1xx) with this code:
import socket
port = 12050
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('', port))
s.listen(1)
conn, addr = s.accept()
print('Connected by ', addr)
imei = conn.recv(1024)
conn.send('\x01')
while True:
try:
data = conn.recv(1024)
if not data: break
print (data)
except socket.error:
print ("Error Occured.")
break
So far I've figured out that conn.send('\x01') doesn't work as it should, and device don't send the rest of data. There were a few questions like this, but none has a good answer. Here you can find documentation of this device.

It must be encoded and ordered (little-/big-endian) if you sending more then one byte. Use something like this:
conn.send(struct.pack('!L', 1))
About connecting to teltonika gps: https://github.com/Kein1945/GPS_Teltonika_Server/

like #uglymaxweber mentioned you have pack it as integer(four bytes) and on python3 you can use the built in to_bytes.
byteorder is little or big endian and the first parameter is the bytesize.
response = 5
conn.send(response.to_bytes(4, byteorder = 'big'))

Python socket to send rows of data

Greetings and apologies in advance if it looks a real novice question. I am new to python, or programming for that matter. I am writing a code that sends data from client to server. The data I need to send is from an csv file, which has around 10,000 rows. Currently I am sending the data in a large buffer as a whole, but I would prefer to send it row by row and also receive it the same way. I am not sure if I should use the split() function or there are any better ways to do the same thing.
The client...
import socket
HOST = 'server IP'
PORT = 42050
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
f = open('csvfile.csv', 'rb')
l = f.read(409600)
while True:
print l
s.send(l)
break
f.close()
print "Done Sending"
s.close()
The server...
import socket
HOST = 'local IP'
PORT = 42050
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
print "Server running", HOST, PORT
s.listen(5)
conn, addr = s.accept()
print'Connected by', addr
while True:
data = conn.recv(409600)
print repr(data)
if not data: break
print "Done Receiving"
conn.close()
Thanks in advance for the help.

im not sure what your question actually is ... but its pretty easy to send and receive lines
#client.py
for line in open("my.csv"):
s.send(line)
#server.py
def read_line(sock):
return "".join(iter(lambda:sock.recv(1),"\n"))
iter(lambda:sock.recv(1),"\n")
is essentially the same as
result = ""
while not result.endswith("\n"): result += sock.recv(1)

Python: using select with socket

I'm newbie in Python.
I wrote a socket server. It can read and send json-data. But I need to do it with select to extend it.
But I have no idea how to do it. I can't understand examples from the Internet - they have input(), sys.stdin and so on (for what??)
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(('0.0.0.0', 8888,))
server_socket.listen(5)
while True:
client, address = server_socket.accept()
data = client.recv(1024)
print('received:', data.decode('utf-8'))
sending_data = bytes(generate_json(), 'utf-8')
print(sending_data)
client.send(sending_data)
client.close()

Sending data to multiple clients

Im creating a simple Client-Server chat system. Im using TCP and Im aware that TCP is end-end. But Im trying to forward the data that I receive from one client to the next client in array. But in the following code, Im trying to send it to all the clients(and even that fails :D)
Here is my code:
from socket import *
from os import *
from threading import *
def multipleClients():
all_clients = []
conn, addr = s.accept()
all_clients.append(conn)
print "is connected :D :)", addr
while True:
data= conn.recv(1024)
if not data:
break
print "message is :", repr(data)
for c in all_clients:
c.send(data)
host='localhost'
port=12000
s=socket(AF_INET, SOCK_STREAM)
s.bind((host, port))
s.listen(5)
print "Server is Running :D :p "
for i in range (5):
Thread(target=multipleClients).start()

TCP is a streaming protocol. You probably need some kind of message-protocol. recv can receive up to 1024 bytes, which can be one message, part of a message or multiple messages at once.
Every thread has only one client, because you have only one accept. You probably want to work with select to manage multiple connections.
