Overview of this book

If you want to learn how best to utilize commonly found patterns and learn best practices in developing applications with Django, this is the book for you. This book, like Django itself, is accessible to amateur and professional developers alike and assumes little in the way of prior experience. Although written for Python 3, the majority of the code in this book works in Python 2 or can be easily translated.

The official Django documentation has been organized by versions at https://docs.djangoproject.com. On any page, you can quickly switch to the corresponding page in the previous versions of Django with a selector on the bottom right-hand section of the page:
