Overview of this book

Learning Python has a dynamic and varied nature. It reads easily and lays a good foundation for those who are interested in digging deeper. It has a practical and example-oriented approach through which both the introductory and the advanced topics are explained. Starting with the fundamentals of programming and Python, it ends by exploring very different topics, like GUIs, web apps and data science. The book takes you all the way to creating a fully fledged application. The book begins by exploring the essentials of programming, data structures and teaches you how to manipulate them. It then moves on to controlling the flow of a program and writing reusable and error proof code. You will then explore different programming paradigms that will allow you to find the best approach to any situation, and also learn how to perform performance optimization as well as effective debugging. Throughout, the book steers you through the various types of applications, and it concludes with a complete mini website built upon all the concepts that you learned.

You can set all sorts of properties such as shape, size, color, margins, borders, fonts, and so on. In this project, I have tried my best to achieve a decent result on the pages, but I'm neither a frontend developer nor a designer, so please don't pay too much attention to how things look. Try and focus on how they work.

Setting up Django

On the Django website (https://www.djangoproject.com/), you can follow the tutorial, which gives you a pretty good idea of Django's capabilities. If you want, you can follow that tutorial first and then come back to this example. So, first things first; let's install Django in your virtual environment:

$ pip install django

When this command...
