Last updated: 19-12-2025

Introduction

The ever-evolving world of networking demands powerful tools for automation and efficiency. Python, a versatile and beginner-friendly programming language, has emerged as a favorite among network engineers for automating repetitive tasks.

Why Python for Network Automation?

Python offers several advantages for network automation:

  • Simple and Readable: Python's syntax is clear and easy to learn, making it accessible to network engineers with limited programming experience.
  • Extensive Libraries: A rich ecosystem of libraries like Paramiko and Netmiko simplifies network interactions, allowing you to connect to devices, send commands, and process outputs.
  • Cross-Platform Compatibility: Python scripts run seamlessly across different operating systems, including Windows, macOS, and Linux, providing flexibility in your network environment.

Ready to Automate? Installing Python 3.9.6 on Windows

This guide walks you through a step-by-step installation of Python 3.9.6 on your Windows machine. While newer versions might be available, 3.9.6 offers stability and compatibility with many network automation libraries as of today (May 5, 2024).

1. Download the Python Installer:

Head over to the official Python downloads page: https://www.python.org/downloads/

Under Windows, locate the version 3.9.6 installer (64-bit or 32-bit depending on your system architecture). Download the appropriate installer file.

2. Run the Installer:

Once the download completed, double click on the setup file for installation.

A Python 3.9.6 (64-bit) Setup pop-up window will appear.

Ensure that both the Install launcher for all users (recommended) and the Add Python 3.9 to PATH checkboxes at the bottom are checked. Select Customize Installation then click on Next.

Set the customize install location “C:\Python39” and click on Install.

When run, a User Account Control pop-up window may appear asking if you want to allow this app to make changes to your device. Click Yes.

A new Python 3.9.6 (64-bit) Setup pop-up window will appear with a setup progress message and a progress bar.

During installation, it will show the various components it is installing and move the progress bar towards completion. Soon, a setup successful message will appear.

3. Verify Installation:

Open a command prompt window and type python --version. If the installation is successful, the Python version information will be displayed.

Conclusion:

You've successfully installed Python on your Windows machine. Now you're ready to explore the vast potential of Python for network automation. In future blog posts, we'll delve deeper into utilizing Python libraries and scripting techniques to automate network tasks and take control of your network.
