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.

Deploying the application with Zappa


Now we have got to a very interesting section of the chapter. We are going to deploy the Flask app that we created using a tool called Zappa (https://github.com/Miserlou/Zappa). Zappa is a tool developed in Python (by Rich Jones, the principal author of Zappa) that makes it very easy to build and deploy serverless Python applications.

The installation is pretty straightforward. Within the virtual environment that we have been using to develop this project, you can just run the pipenv command:

pipenv install zappa

After the installation, you can start the configuration. You just need to make sure that you have a valid AWS account and the AWS credentials file is in place. If you followed this chapter from the beginning and installed and configured the AWS CLI you should be all set.

To configure Zappa for our project you can run:

zappa init

You will see the ASCII Zappa logo (very beautiful BTW), and it will start asking some questions. The first one is:

Your Zappa...
