The main objective of the book is to help aspiring data scientists to learn python as fast as possible and as deeply as required for the role. Nevertheless, this can be used by data scientists at any level that are seeking for a great reference or as a visual cheat sheet for Python. I have used two most important tools that I consider are essential for effective learning – 1. Infographics that helps in maximum memory retention, and 2. Examples to help in easy ingestion of concepts.
