Python is an extremely popular language, and is an excellent choice for first time programmers, because it is simple to get started with, but extremely powerful once you get to know it. Python in the language of choice for machine learning and web development, but is can also be used for anything from system scripts to games to desktop applications. It is also embedded in many existing applications to provide a scripting mechanism, which can be used to automate many applications such as Paintshop or Blender.

This book will help you learn Python whether you are a complete beginner or you already have experience programming in other languages. It teaches all the core features of the language, step by step, with example code.
