The most up-to-date book on Flask on the market

Create your own world-class applications and master the art of Flask by unravelling its enigma through this journey

This step-by-step tutorial is packed with examples on blending different technologies with Flask to get you up and running

Description

This book will take you on a journey from learning about web development using Flask to building fully functional web applications. In the first major project, we develop a dynamic Headlines application that displays the latest news headlines along with up-to-date currency and weather information. In project two, we build a Crime Map application that is backed by a MySQL database, allowing users to submit information on and the location of crimes in order to plot danger zones and other crime trends within an area. In the final project, we combine Flask with more modern technologies, such as Twitter's Bootstrap and the NoSQL database MongoDB, to create a Waiter Caller application that allows restaurant patrons to easily call a waiter to their table. This pragmatic tutorial will keep you engaged as you learn the crux of Flask by working on challenging real-world applications.

Who is this book for?

Have you looked at PHP and hated the clunky bloated syntax? Or looked at .Net and wished it was more open and flexible? Maybe you’ve tried your hand at GUI libraries in Python and found them hard to use? If your answer to any one of these questions is a yes, then this is just the book for you. It is also intended for people who know the basics of Python and want to learn how to use it to build powerful solutions with a web front-end.

"While starting to learn a new framework for web development, it is really important to learn basics of the web development, framework chosen and language in which it is written.""Flask by Example" is one such book where you will start as a novice into flask development and learn step by step through live projects mentioned in book. Starting from first chapter, it will give you basic ideas about how web development works, what are web servers, creating backend functionality using python, creating templates using Jinja 2.0, integrating html, jquery and bootstrap into web application, integrating with MySQL database and MongoDB database, etc. and it will take you to the advanced web development like making code live on aws, using git for source code maintenance, making site live on apache server, etc. Everyone who wants to learn web development into python flask framework, whether you are experienced web developer into some other language or framework OR you are a beginner, will find this book useful to learn.NOTE: I have been a part of this book as technical reviewer, and this review is based on my experience about the content of the book and way it is presented to the readers

So far (into chapter 3), this book does a good job getting up and running learning Flask. The book assumes some knowledge of Linux, for example in my Ubuntu box I wasn't in the right context when installing Python, and Flask and it caused my web server not to run properly.

Xiaobo Cao Jul 13, 2017

The book explains Flask and a couple of its extensions. The explanation is detailed and clear, and contents covered in this book are useful for starting with building a web site. I personally felt that I learned a lot from it and have mastered the basics to build a Flask website.I really like the three projects used in the book. They really demonstrate lots of common problems and useful tools/ways to tackle them.The only reason I take one star off is because I saw a few typos in the book, both in the text and code. As a book introducing coding, the typo in the code or the text explaining the code will be misleading and takes lots of time for the readers to figure out the error.

Lawrence Nov 20, 2016

Am only at page 24 of the book and the code there does not work. It only gives list index out of range error around first_article = feed['entries'][0]. How can this be solved?

Kristin Apr 29, 2016

First I would like to say for the most up to date book on the market I expected it to be Python 3. I am almost halfway through and have had to adjust a couple of things so far to work with Python3. But so far it's been simple things like changing imported modules. The book is well written and really does a great job of explaining things simply even at the expense of going back and refactoring code to make it more concise. I recommend this book to anyone wanting to learn flask. Only knock so far is not being in python3.
