Python for Network Automation: A Comparative Study of Tools, Architectures, and Industry Use Cases

Abstract

Managing large-scale networks has become increasingly complex in today's technology-driven environment. Traditional manual configurations no longer meet the speed, consistency, or scalability that modern organizations demand. Network automation is no longer optional, but it is essential. Python is a programming language valued for its readability and rich ecosystem, has proven to be a pivotal tool in network management. It enables engineers to automate manual routine network tasks, reduce the risk of human error, and integrate seamlessly with a wide range of devices and protocols. This paper evaluates Python’s role in network automation through a comparative study of tools (Netmiko, NAPALM, Ansible), real-world use cases, and emerging trends like intent-based networking. We also highlight current academic perspectives, outline implementation challenges, and provide best practices based on real-world scenarios. The goal is to present a balanced, human-written overview that can help engineers, IT managers, and researchers understand how Python is reshaping the way networks are designed and managed.
