Preface
In the last few years, Python has been very popular and has become the first choice of students, teachers as well as company officials. It is used in different fields such as education, software development, website development, and in research. In education, it helps students to learn the programming language in an easy and efficient manner. In the IT field, it can be used as a superb language for developing software as well as websites. It can also be integrated with different platforms like Django. In research, Python programming can be used in simulations or machine learning. It offers several benefits. The primary goal in the development of this book is to create a pedagogical sound and accessible book that emphasizes on the core concepts of Python programming. This book can be used to develop the Python concepts in an easy way. This book contains many examples to show the working of a particular code construct. This book is very helpful to learn the basic and advance concepts of Python programming. This book is divided into 14 chapters and it provides a detailed description of the core concepts of Python programming.
Chapter 1 introduces the concepts of Python. It describes how to solve computational problems using Python. It also explains the importance of using Python.
