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.

The year is 2018 and by now we've probably all heard dozens of stories about companies leaking our sensitive data, including passwords, to hackers. In a lot of these cases, the passwords that were leaked were stored with extremely poor cryptography, meaning that they could be cracked with ease. In some cases, the passwords were even stored in plain text!

Either way, this negligence has led to the leak of millions of users' email and password combinations. This would not be such an issue if we used different passwords for every online account we made... but unfortunately, we are lazy and password reuse is quite common practice. Therefore, the responsibility for mitigating some of the damage done by hackers infiltrating our servers falls to us, the developers.

In October 2016, the popular video sharing platform Dailymotion suffered a data breach in which 85 million accounts were stolen. Of those 85 million accounts, 18 million had passwords attached...
