Socket Programming in Python 🎯

Welcome to our comprehensive guide on Socket Programming in Python! This tutorial is designed for both beginners and intermediates, so let's dive in together! 🐠

Understanding Socket Programming 📝

Socket programming is a method of communication between two devices over a network, using sockets as the interface. In Python, sockets are handled by the socket module.

Why is it important? Socket programming allows you to create networked applications, like file transfer, web servers, and client-server applications.

Setting Up the Socket 💡

Before we start coding, let's install the necessary module:

bash

pip install socket

Now, let's create our first server and client.

Creating the Server 📝

python

import socket

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('localhost', 12345))
server.listen(5)

print('Server started on port 12345')

client, addr = server.accept()

data = client.recv(1024)
print('Received:', data)
client.send(data)

client.close()
server.close()

Save this as server.py. Now, let's create the client.

Creating the Client 📝

python

import socket

client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(('localhost', 12345))

message = 'Hello, World!'
client.send(message.encode())

data = client.recv(1024)
print('Received:', data.decode())

client.close()

Save this as client.py.

Now, run the server script (python server.py), then the client script (python client.py). You should see the message 'Hello, World!' printed on both the server and client.
