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.

Querying Spotify's web API


So far, we have only prepared the terrain and now things start to get a bit more interesting. In this section, we are going to create the basic functions to send requests to Spotify's Web API; more specifically, we want to be able to search for an artist, get an artist's list of albums, get a list of tracks in that album, and finally we want to send a request to actually play a given track in Spotify's client that is currently active. It can be the browser, a mobile phone, Spotify's client, or even video game consoles. So, let's dive right into it!

To start off, we are going to create a file called request_type.py in the musicterminal/pytify/core directory with the following contents:

from enum import Enum, auto


class RequestType(Enum):
    GET = auto()
    PUT = auto()

We have gone through enumerations before, so we won't be going into so much detail. It suffices to say that we create an enumeration with GET and PUT properties. This will be used to notify the function...
