How Do I Install Python Web Server?


Scott Campbell

Installing a Python web server is a crucial step for anyone looking to develop and deploy web applications using Python. In this tutorial, we will walk you through the process of installing a Python web server on your local machine.

Step 1: Download Python

To get started, you need to have Python installed on your computer. If you don’t have it already, head over to the official Python website at and download the latest version of Python for your operating system.

Step 2: Install Python

Once the download is complete, locate the installer file and run it. Follow the installation wizard and make sure to select the option to add Python to your system’s PATH variable. This will allow you to run Python commands from any directory in your command prompt or terminal.

Step 3: Check Installation

To ensure that Python has been installed correctly, open a command prompt (Windows) or terminal (macOS/Linux) and type python --version. This command will display the installed version of Python.

If you see the version number, congratulations! You have successfully installed Python.

Step 4: Install a Web Server Framework

Python offers several web server frameworks that can be used to develop web applications. One of the most popular frameworks is Flask.

To install Flask, open your command prompt or terminal and type pip install flask. This will download and install Flask along with its dependencies.

Alternative Frameworks:

  • Django – A powerful web framework for building complex applications.
  • Bottle – A lightweight and simple framework that is ideal for small projects.
  • Pyramid – A flexible framework that allows you to choose the components you need.

Step 5: Set Up a Basic Web Server

Now that you have a web server framework installed, it’s time to set up a basic web server. Create a new file with a .py extension, for example, Open the file in your favorite text editor and add the following code:

from flask import Flask
app = Flask(__name__)

def hello_world():
    return 'Hello, World!'

if __name__ == '__main__':

In this example, we are using Flask to create a basic web application that displays “Hello, World!” when accessed at the root URL /. Feel free to modify this code to suit your needs.

Step 6: Run the Web Server

To start the web server, open your command prompt or terminal and navigate to the directory where you saved Type python and hit enter. The web server will start running on http://localhost:5000/.

You can now open your web browser and navigate to http://localhost:5000/. You should see the message “Hello, World!”

displayed in your browser. Congratulations! You have successfully installed and set up a Python web server.

Closing Thoughts

In this tutorial, we covered the process of installing a Python web server on your local machine. We also explored different web server frameworks and learned how to set up a basic web server using Flask. With this knowledge, you are ready to start building your own web applications using Python.

Remember, this is just the beginning. As you dive deeper into web development with Python, you will discover more advanced topics and techniques that will help you build powerful and scalable applications.

Keep coding and happy web developing!
