Code Examples

Getting Started with socket

import socket\n\n# Create a socket object\ns = socket.socket(socket.AF_INET, socket.SOCK_STREAM)\n\n# Define the port on which you want to connect\nport = 12345\n\n# connect to the server on local computer\ns.connect(('127.0.0.1', port))\n\n# receive data from the server\nprint(s.recv(1024))\n\n# close the connection\ns.close()

Advanced socket Example

import socket\n\n# Create a socket object\nserver_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)\n\n# Get local machine name\nhost = socket.gethostname()\n\nport = 9999\n\n# Bind to the port\nserver_socket.bind((host, port))\n\n# Queue up to 5 requests\nserver_socket.listen(5)\n\nwhile True:\n   # Establish a connection\n   client_socket, addr = server_socket.accept()\n   print(f'Got a connection from {addr}')\n   \n   message = 'Thank you for connecting'+ "\r\
"\n   client_socket.send(message.encode('ascii'))\n   client_socket.close()
