socket programming in python code example

Example 1: send data through tcp sockets python

import socket
TCP_IP = '127.0.0.1'
TCP_PORT = 5005
BUFFER_SIZE = 1024
MESSAGE = "Hello, World!"
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))
s.send(MESSAGE)
data = s.recv(BUFFER_SIZE)
s.close()
print "received data:", data

Example 2: socket programming in python

#!/usr/bin/env python3

import socket

HOST = '127.0.0.1'  # Standard loopback interface address (localhost)
PORT = 65432        # Port to listen on (non-privileged ports are > 1023)

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
    s.bind((HOST, PORT))
    s.listen()
    conn, addr = s.accept()
    with conn:
        print('Connected by', addr)
        while True:
            data = conn.recv(1024)
            if not data:
                break
            conn.sendall(data)

Example 3: python socket server

import socket

socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.bind(('', 15555))

while True:
        socket.listen(5)
        client, address = socket.accept()
        print "{} connected".format( address )

        response = client.recv(255)
        if response != "":
                print response

print "Close"
client.close()
stock.close()

Example 4: python network programming

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.
s.bind((host, port))        # Bind to the port

s.listen(5)                 # Now wait for client connection.
while True:
   c, addr = s.accept()     # Establish connection with client.
   print 'Got connection from', addr
   c.send('Thank you for connecting')
   c.close()                # Close the connection

Example 5: tcp client using sockets in python

from socket import *
import sys
import json


serverName = ""
serverPort = 6100


clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.connect((serverName, serverPort))

sample_data = {
	"Aparna" : 1,
	"Pooja" : 2,
	"Shreya" : 3,
	"Tanishq" : 4
}

serialized_data = json.dumps(sample_data) #data serialized

# clientSocket.send(str.encode(sample_data))
clientSocket.send(str.encode(serialized_data))

response_data = clientSocket.recv(1024)
print("Response data from server : ", response_data.decode())

clientSocket.close()

Example 6: socket programming in python

#!/usr/bin/python           # This is server.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.
s.bind((host, port))        # Bind to the port

s.listen(5)                 # Now wait for client connection.
while True:
   c, addr = s.accept()     # Establish connection with client.
   print 'Got connection from', addr
   c.send('Thank you for connecting')
   c.close()                # Close the connection
