I liked it. I'm not a newbie and knew how to develop Flask apps, so this book most of the time was too basic or just told about the things I know, butI liked it. I'm not a newbie and knew how to develop Flask apps, so this book most of the time was too basic or just told about the things I know, but there were places where I added bookmarks and will come back soon when I will touch the code, places where I can use those tips or new things I read about. Generally it is well written book and if you are looking for a resource to start learning Flask framework (which is really awesome framework to work with) - grab it, run it through and make sure you try out the things while you see them in the book. Later on you will find your own way to develop apps with Flask (as it gives a lot of freedom), but the book gives a great overview not only about Flask itself, but also most common and popular extensions to be used. No regrets that I spent some money on this book....more
