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.

Case study– Building a web application using the REST API

In this chapter, we learned how to build a simple web application using Flask and how to add a REST API to a business logic layer using a Flask extension. In the real world, web applications are typically three tiers: web layer, business logic layer, and data access layer. With the popularity of mobile apps, the architecture has evolved to have a REST API as a building block for the business layer. This affords the freedom of building web apps and mobile apps using the same business logic layer. Moreover, the same API can be available for B2B interactions with other vendors. This type of architecture is captured in Figure 10.2:

In our case study, we will develop a web application on top of the REST API application that was developed for the Student model object in the previous code example. At a high level, we will have the components in...
