Introduction

Welcome to the Python Workshop. This book is for anyone new to the Python programming language. Our objective is to teach you Python so that you can solve real-world problems as a Python developer and data scientist.

This book will combine theory, examples, exercises, questions, and activities for all core concepts; so that you can learn to use Python best practices to solve real-world problems. The exercises and activities have been chosen specifically to help you review the concepts covered and extend your learning. The best way to learn Python is to solve problems on your own.

The material (in this book) is targeted at beginners but will be equally as beneficial to experienced developers who are not yet familiar with Python. We are not teaching computer science per se, but rather Python, the most beautiful and powerful coding language in the world. If you have never studied computer science, you will learn the most important concepts here, and if you have studied computer science, you will discover tools and tricks for Python that you have never seen before.

Python has become the most popular programming language in the world due to its simple syntax, extensive range, and dominance in the field of machine learning. In this book, you will become fluent in Python syntax, and you will take significant steps toward producing Pythonic code. You will gain experience in Python development, data science, and machine learning.

Many introductory Python books provide full introductions to computer science. Learning computer science with Python is an excellent way to start, but it is not the method of this book. Units on software development and data science are rarely covered in such books. They may be touched upon, but here, they represent 40% of our book.

By contrast, many books on software development and data science are not designed for beginners. If they are, the Python fundamentals that they teach are usually summarized in one brief unit. This book devotes considerable space to Python fundamentals and essentials. Beginners are not only welcome; they are guided every step of the way.

In addition to the unique focus on Python fundamentals and essentials, the fact that the content is written by seasoned educators, data scientists, and developers makes this Python book more than just a text or reference.

Python is not the language of tomorrow; Python is the language of today. By learning Python, you will become empowered as a developer, and you will gain a significant edge over the competition. The journey will be fun, compelling, challenging, and ultimately, rewarding.
