Overview of this book

Python is the language of choice for millions of developers worldwide that builds great web services in RESTful architecture. This second edition of Hands-On RESTful Python Web Services will cover the best tools you can use to build engaging web services. This book shows you how to develop RESTful APIs using the most popular Python frameworks and all the necessary stacks with Python, combined with related libraries and tools. You’ll learn to incorporate all new features of Python 3.7, Flask 1.0.2, Django 2.1, Tornado 5.1, and also a new framework, Pyramid. As you advance through the chapters, you will get to grips with each of these frameworks to build various web services, and be shown use cases and best practices covering when to use a particular framework. You’ll then successfully develop RESTful APIs with all frameworks and understand how each framework processes HTTP requests and routes URLs. You’ll also discover best practices for validation, serialization, and deserialization. In the concluding chapters, you will take advantage of specific features available in certain frameworks such as integrated ORMs, built-in authorization and authentication, and work with asynchronous code. At the end of each framework, you will write tests for RESTful APIs and improve code coverage. By the end of the book, you will have gained a deep understanding of the stacks needed to build RESTful web services.

Installing packages with the requirements.txt file to simplify our common tasks


Make sure you quit Flask's development server. You just need to press Ctrl + C in the Terminal or Command Prompt window in which it is running.

Now, we will install a number of additional packages. Make sure you have activated the virtual environment we created in the previous chapter and named Flask01. After you activate the virtual environment, it is time to run numerous commands, which will be the same for either macOS, Linux, or Windows.

Now, we will edit the existing requirements.txt file to specify the additional set of packages that our application requires to be installed in any supported platform. This way, it will be extremely easy to repeat the installation of the specified packages with their versions in any new virtual environment.

Use your favorite editor to edit the existing text file named requirements.txt within the root folder for the virtual environment. Add the following lines after the last...
