What Is a Web Server Python?


Heather Bennett

A web server is a software application that handles HTTP requests sent by clients, such as web browsers, and delivers the requested web pages to those clients. Python, being a versatile programming language, provides several options for creating web servers.

Python’s Built-in Web Servers

Python offers built-in modules that allow developers to quickly create simple web servers. These modules include:

  • http.server: This module provides a basic HTTP server implementation in Python. It is part of the standard library and can be used to serve static files or simple websites.
  • socketserver: This module allows developers to create network servers using various protocols, including HTTP.

    It provides a framework for building custom web servers in Python.

  • SimpleHTTPServer: This module is an old version of http.server and is available in older versions of Python. It serves files from the current directory over HTTP.

Web Frameworks for Python Web Servers

To build more complex and robust web applications, developers often use web frameworks that provide higher-level abstractions and additional functionality. Some popular Python web frameworks include:

  • Django: Django is a high-level Python web framework that follows the model-view-controller (MVC) architectural pattern. It includes features like an ORM (Object-Relational Mapping), authentication, routing, and template engine.
  • Flask: Flask is a lightweight web framework that focuses on simplicity and extensibility.

    It provides tools for handling HTTP requests, routing, sessions, and templating.

  • Bottle: Bottle is another lightweight Python web framework known for its simplicity and minimalistic design. It has a built-in web server and can be used for small projects or APIs.

Deploying Python Web Servers

Once you have developed your Python web server, you need to deploy it on a production environment to make it accessible to users. There are various options for deploying Python web servers:

  • Virtual Private Server (VPS): You can deploy your Python web server on a VPS provider like Amazon EC2, DigitalOcean, or Linode. This gives you full control over the server configuration and allows you to scale your application as needed.
  • Platform as a Service (PaaS): PaaS providers like Heroku, Google App Engine, and PythonAnywhere handle the infrastructure management for you.

    They provide an easy way to deploy and manage your Python web servers without worrying about server administration.

  • Docker Containers: Docker allows you to package your Python web server along with its dependencies into a container. This container can then be deployed on any system that has Docker installed, making it highly portable.


In conclusion, Python offers several options for creating web servers ranging from simple built-in modules to powerful frameworks. Whether you choose to use the built-in modules for simple tasks or leverage the capabilities of frameworks for complex applications, Python provides the flexibility and tools needed to develop and deploy robust web servers.
