How Create Web Server in Python Explain With Example?


Larry Thompson

In this tutorial, we will learn how to create a web server in Python. Building a web server in Python can be a great way to understand the basic concepts of network programming and how the web works.

We will go through the process step by step, and I’ll provide examples along the way to help you understand better.


  • Basic knowledge of Python programming language
  • Understanding of HTTP protocols

Setting Up the Environment

Before we start building our web server, we need to make sure that we have Python installed on our system. You can download and install Python from the official website if you haven’t done so already.

Once you have Python installed, open your favorite text editor and create a new file called “”. This will be our main script for the web server.

Importing Required Libraries

To create a web server in Python, we need to import the “http.server” module. This module provides classes for implementing HTTP servers that can receive requests and respond accordingly.
Open the “” file and add the following line at the top:

import http.server

Defining Server Class

Next, let’s define a class called “WebServer” that inherits from the base class provided by the “http. This class will handle incoming requests and send back responses.
Add the following code below your import statement:

class WebServer(http.server.BaseHTTPRequestHandler):

Now, let’s override some methods provided by the base class to customize our web server’s behavior. We will override the “do_GET” method to handle GET requests and send a simple response.
Add the following code inside the “WebServer” class:

def do_GET(self):
    self.send_header('Content-type', 'text/html')
    message = "Hello, World!"

In the above code, we first send a response header with a 200 status code and the content type set to “text/html”. Then, we send an empty line to indicate the end of the headers.

Finally, we write our message (in this case, “Hello, World!”) to the response body using the “wfile” object.

Running the Server

To start our web server, we need to create an instance of our “WebServer” class and pass it to the “http.HTTPServer” class. This will create a server object that listens for incoming requests on a specific port.
At the end of your script, add the following lines:

web_server = http.HTTPServer(('localhost', 8000), WebServer)

In this example, our web server will listen on localhost (127.0.1) at port 8000. You can change these values if you prefer a different host or port number.

Save your script and open your terminal or command prompt. Navigate to the directory where you saved your script and run it using the following command:

$ python

Once your server is running, open your web browser and navigate to “http://localhost:8000”. You should see the message “Hello, World!” displayed on the page.

Congratulations! You have successfully created a basic web server in Python.


In this tutorial, we learned how to create a web server in Python using the “http. We covered the basic steps of setting up the environment, importing required libraries, defining a server class, handling incoming requests, and running the server.

It’s important to note that this is just a simple example to get you started. There are many more advanced features and functionalities you can explore as you dive deeper into web development with Python.

I hope you found this tutorial helpful. Happy coding!
