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.

Setting up the environment


Like all the previous chapters, we are going to start off this chapter by setting up the environment that we need to develop our services on. Let's start by creating our working directory:

mkdir microservices && cd microservices

Then, we create our virtual environment with pipenv:

pipenv --python ~/Install/Python3.6/bin/python3.6

Note

If you don't know how to use pipenv, in the section Setting up the environment in Chapter 4, Exchange Rates and the Currency Conversion Tool, there is a very good introduction about how to get started with pipenv.

With the virtual environment created, we need to install the project dependencies. For this project, we are going to install Django and the Django REST Framework:

pipenv install django djangorestframework requests python-dateutil

The reason that we are using Django and the Django REST Framework instead of a simpler framework like Flask is that the main idea of this project is to provide a separation of concerns, creating...
