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.

Introducing serverless functions

A serverless function is a model that can be used to develop and execute software components or modules without needing to know or worry about an underlying hosting platform. These software modules or components are known as Lambda functions or Cloud functions in the public cloud providers' product offerings. Amazon was the first vendor that offered such serverless functions on its AWS platform as AWS Lambda. It was followed by Google and Microsoft, which offer Google Cloud Functions and Azure Functions, respectively.

Typically, a serverless function has four components, as follows:

These four components are described next:

  • Functional code: This is a programming unit that performs certain tasks as per the business or functional goal of the function. For example, we can write a serverless function to process an input stream of data or write a scheduled...
