In Detail

Flask is a simple and minimalistic framework, which makes it easy to learn and beginner-friendly. It is also well-developed and exceptionally well-documented with an advanced plugin system, consisting of all the features of a top-end framework and is extremely powerful to use. It empowers you to harness the flexibility of the web through the elegance of Python without needing to worry about installations and compatibility.

This book will take you on a journey through learning about web development using Python to building fully-functional web applications. We start off with a simple web application that greets visitors with the time-honored tradition of "Hello, World!" In the first major project, we move on to developing a dynamic and useful "headlines" application that displays the latest news headlines along with up-to-date currency and weather information. In project two, we build a dynamic "crime map" that is backed by a SQL database, allowing users to submit information and the location of crimes in order to plot danger-zones and other crime trends within an area. In the final project, we look at how to use Flask with more modern technologies, including Twitter's Bootstrap and the NoSQL database MongoDB. We combine these to create a "restaurant notification" application that allows restaurant patrons to easily call a waiter to their table.

This pragmatic tutorial will keep you engaged as you learn the nitty-gritty of Flask by working on challenging real-world applications.
