Python Programming Blueprints

By: Daniel Furtado, Marcus Pennington

Overview of this book

Python is a very powerful, high-level, object-oriented programming language. It's known for its simplicity and huge community support. Python Programming Blueprints will help you build useful, real-world applications using Python. In this book, we will cover some of the most common tasks that Python developers face on a daily basis, including performance optimization and making web applications more secure. We will familiarize ourselves with the associated software stack and master asynchronous features in Python. We will build a weather application using command-line parsing. We will then move on to create a Spotify remote control where we'll use OAuth and the Spotify Web API. The next project will cover reactive extensions by teaching you how to cast votes on Twitter the Python way. We will also focus on web development by using the famous Django framework to create an online game store. We will then create a web-based messenger using the new Nameko microservice framework. We will cover topics like authenticating users and, storing messages in Redis. By the end of the book, you will have gained hands-on experience in coding with Python.

Authenticating with Spotify's web API


Now that we have the code to load the configuration file for us, we are going to start coding the authentication part of our framework. Spotify currently supports three kinds of authentication: authorization code, client credentials, and implicitly grant. We are going to implement authorization code and client credentials in this chapter, and we will start by implementing the client credentials flow, which is the easiest to start with.

The client credentials flow has some disadvantages over the authorization code flow because the flow does not include authorization and cannot access the user's private data as well as control playback. We will implement and use this flow for now, but we will change to authorization code when we start implementing the terminal player.

First, we are going to create a file called authorization.py in the musicterminal/pytify/auth directory with the following contents:

from collections import namedtuple


Authorization = namedtuple...
