In this chapter, we covered the working examples of various terminology/techniques that we will use while performing network automation. This chapter also introduced readers to writing a good program, which is a key requirement in a collaborative environment. This chapter also explained the use of Git and GitHub as a code check-in, and why it is important and advantageous to publish the code on a server as compared to a local copy. Readers were also introduced to making a choice between two popular scripting languages, Python and PowerShell, while working on mixed environments or platforms. The short examples given will help the reader to understand the practical usage of Python; they also expose multiple concepts that will be used regularly when writing a program.
Finally, the use cases are a summation of all the previous learning and show how to use that knowledge in a bigger project. Some of the concepts given in the use cases are key to network-automation programs that will be developed further in the next chapter.
The next chapter will go deeper into how to write scripts using Python, with a specific focus on usability for network engineers. There will be samples, tips, and best practices as well.
