First of all, this book focusses on breaking the mental blocks to make sure the learner, with an open mind, is able to understand all the concepts. The book focuses on making sure the absolute fundamentals of Python which every Python developer needs, are introduced in a semitechnical language to make sure the learner not only finds Python easy but also finds programming as a whole very easy.
The code examples in the book are kept small & simple encouraging the learner to try out the code examples.
The book is spread over 9 chapters. The 9 chapters are as follows:
