Python for Geeks

By: Muhammad Asif

Overview of this book

Python is a multipurpose language that can be used for multiple use cases. Python for Geeks will teach you how to advance in your career with the help of expert tips and tricks. You'll start by exploring the different ways of using Python optimally, both from the design and implementation point of view. Next, you'll understand the life cycle of a large-scale Python project. As you advance, you'll focus on different ways of creating an elegant design by modularizing a Python project and learn best practices and design patterns for using Python. You'll also discover how to scale out Python beyond a single thread and how to implement multiprocessing and multithreading in Python. In addition to this, you'll understand how you can not only use Python to deploy on a single machine but also use clusters in private as well as in public cloud computing environments. You'll then explore data processing techniques, focus on reusable, scalable data pipelines, and learn how to use these advanced techniques for network automation, serverless functions, and machine learning. Finally, you'll focus on strategizing web development design using the techniques and best practices covered in the book. By the end of this Python book, you'll be able to do some serious Python programming for large-scale complex projects.

Interacting with network devices

Python is a popular choice for network automation because it is easy to learn and can be used to integrate with network devices directly, as well as through NMS. In fact, many vendors, such as Nokia and Cisco, support Python runtimes on their network devices. The option of on-device Python runtimes is useful for automating tasks and activities in the context of a single device. In this section, we will focus on the off-device Python runtime option. This option will give us the flexibility to work with multiple devices at a time.

Important note

For all the code examples provided in this section, we will use a virtual network device from Cisco (IOS XR with release 7.1.2). For integration with the NMS we will use the Nokia NSP system.

Before working with Python so that we can interact with network devices, we will discuss the protocols that are available for communicating with network devices.
