Running a Python Web Server

Python is a versatile programming language that can be used for various tasks, including running a web server. In this tutorial, we will explore different methods to run a Python web server and provide step-by-step instructions along the way.

Method 1: Using the http.server module

The http.server module in Python provides a simple way to run a basic web server. Here’s how you can do it:

  • Open your preferred text editor and create a new file with a .py extension.
  • Start by importing the http.server module:

import http.server
import socketserver

  • Create a class that extends the SimpleHTTPRequestHandler class:

class MyHandler(http.server.SimpleHTTPRequestHandler):

Method 2: Using Flask

Flask is a popular micro web framework for Python. It provides more advanced features and flexibility compared to the basic server provided by the http.server module. To run a Flask web server:

Step 1: Install Flask

If you haven’t installed Flask yet, open your command prompt or terminal and run the following command:

pip install flask

Step 2: Create a Python file

Create a new file with .py extension in your text editor. Let’s call it ``. Start by importing the necessary modules:

from flask import Flask

app = Flask(__name__)

Method 3: Using Django

Django is another powerful web framework for Python that provides extensive features and capabilities for building complex web applications. Running a Django web server involves more steps compared to the previous methods, but it offers greater flexibility.

Step 1: Install Django

If you haven’t installed Django yet, open your command prompt or terminal and run the following command:

pip install django

Step 2: Create a new Django project

In your command prompt or terminal, navigate to the directory where you want to create your project. Then, run the following command:

django-admin startproject myproject


Running a Python web server can be done using various methods, each with its own advantages and use cases. Whether you choose to use the http.server module for basic functionality, Flask for more advanced features, or Django for complex web applications, Python provides excellent options for running a web server.

Remember to consider your specific requirements and choose the method that best suits your needs. Happy coding!
