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.

Summary

In this chapter, we introduced network automation, along with its benefits and the challenges it provides for telecom service providers. We also discussed the key use cases of network automation. After this introduction, we discussed the transport protocols that are available for network automation to interact with network devices. Network automation can be adopted in many ways. We started by looking at how to directly interact with network devices using the SSH protocol in Python. We used the Paramiko, Netmiko, and NAPALM Python libraries to fetch configuration from a device and we elaborated on how to push this configuration to a network device. Next, we discussed how to use NETCONF with Python to interact with a network device. We provided code examples for working with NETCONF and used the ncclient library to fetch an IP interface configuration. We also used the same library to update an IP interface on a network device.

In the last part of this chapter, we explored...
