Building a Python-based Web Server

In today's digital age, having a strong online presence is crucial for individuals and businesses alike. Whether you want to showcase your portfolio, start an online store, or create a platform for your innovative ideas, a website is your gateway to the online world. To make your website accessible to the vast internet audience, you need a web hosting solution.

In this blog, we will explore the fundamentals of web hosting and guide you through the process of building a Python-based web server. Python is a versatile and powerful programming language, making it an excellent choice for creating web servers. We will cover the following topics:

Understanding Web Hosting

Web hosting is the service that enables individuals and organizations to make their websites accessible over the internet. When you create a website, you essentially create a collection of files (HTML, CSS, JavaScript, images, etc.). These files need to be stored on a server connected to the internet, so that when users enter your website's URL in their browsers, they can access these files and view your website.

Web hosting companies provide server space and other resources to store your website's files and ensure they are available 24/7. There are various types of web hosting, including shared hosting, virtual private servers (VPS), dedicated servers, and cloud hosting. Each type has its own advantages and limitations, and your choice will depend on your website's needs and your budget.

Choosing a Hosting Provider

Selecting the right hosting provider is a critical decision. Factors to consider include

  1. Server Uptime and Reliability: Look for a hosting provider that guarantees high server uptime (99.9% or higher) to ensure your website is accessible round the clock.
  2. Performance and Speed: The hosting provider should offer fast server response times, as slow-loading websites can negatively impact user experience.
  3. Customer Support: Check for responsive and helpful customer support, as you might encounter technical issues that require assistance.
  4. Scalability: Ensure that the hosting plan you choose allows you to scale your resources as your website grows.
  5. Security Features: Look for hosting providers that implement robust security measures to protect your website from cyber threats.
  6. Cost: Consider your budget and compare different hosting packages to find one that suits your needs.

Popular hosting providers include Bluehost, SiteGround, HostGator, and AWS (Amazon Web Services).

Requirements for Our Python Web Server

For building a basic Python web server, we will use the built-in http.server module in Python 3. This module provides simple HTTP server capabilities and is suitable for development and testing purposes. For production-grade applications or high-traffic websites, you would need to explore more sophisticated web server frameworks like Flask, Django, or FastAPI.

To follow along with this tutorial, make sure you have the following prerequisites

Building the Python Web Server

Now let's dive into the process of building a basic Python web server using the http.server module. This server will be capable of handling HTTP requests and serving static files.

Create a Project Folder

Start by creating a new folder for your project. Name it something meaningful, like "PythonWebServer," and navigate to that folder in your terminal or command prompt.

Write Python Code

Inside the project folder, create a new file named server.py. Open this file in your text editor or IDE and add the following code

import http.server
import socketserver

PORT = 8000

Handler = http.server.SimpleHTTPRequestHandler

with socketserver.TCPServer(("", PORT), Handler) as httpd:
    print(f"Server started at localhost:{PORT}")

This code imports the necessary modules, sets the server's port number (you can change it if needed), and uses SimpleHTTPRequestHandler to handle incoming HTTP requests. It creates a server object that listens on localhost ( and the specified port.

Run the Server

To run the server, open your terminal or command prompt, navigate to the project folder, and execute the following command:python server.py

You should see the message "Server started at localhost:8000." This means your Python web server is up and running!

Access Your Website

Open your web browser and enter http://localhost:8000 in the address bar. Voilà! You should see your website served by the Python web server. By default, the server will look for an index.html file in the project folder and display it as the home page.

Deploying Your Web Server

While running the Python web server locally is useful for development and testing, it is not a suitable solution for production deployment. For that, you would need a reliable web hosting provider that supports Python applications. The deployment process might involve

The exact steps for deployment can vary depending on the hosting provider and the server configuration. Many providers offer detailed documentation or support to guide you through the process.


In this blog, we explored the basics of web hosting and learned how to build a simple Python-based web server using the http.server module. While this basic server is suitable for development and testing, remember that production-grade applications would require more robust and feature-rich web server frameworks.

Web hosting is a critical aspect of any online venture, and choosing the right hosting provider can significantly impact your website's performance and user experience. Consider your website's needs, scalability requirements, and budget before selecting a hosting plan.

With Python's versatility and the vast number of web frameworks available, you can build complex and dynamic web applications that cater to your specific needs. So, go ahead and explore the world of web hosting and Python web development to bring your ideas to life on the internet! Happy coding!
