Python, known for its simplicity and versatility, is not only a popular language for web development and data science but also a powerful tool for network programming.

In this article, we will explore the basics of Python network programming, understand how to work with sockets, create client-server applications, and dive into practical examples to help you get started on your networking journey.

Getting Started with Sockets

At the core of network programming in Python are sockets. Sockets allow communication between two nodes on a network. To begin, let’s create a simple TCP server using sockets:

import socket

# Create a socket object
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Bind the socket to a specific address and port
server_socket.bind(('127.0.0.1', 12345))

# Listen for incoming connections
server_socket.listen(5)

print("Server is listening on port 12345")

# Accept incoming connections
client_socket, client_address = server_socket.accept()

print(f"Connection from {client_address}")

# Send data to the client
client_socket.send(b"Hello from the server!")

# Close the…
