Learning a programming language requires understanding code and writing it effectively. This book offers quizzes to improve skills in reading and understanding code, while the exercises aim to improve writing code skills.Each chapter starts with an explanation and code examples and is followed by exercises and quizzes, offering an opportunity for self-testing and understanding which level you achieved.This book goes beyond the traditional approach by explaining Python syntaxes with real-world code examples. This approach makes learning exciting and ensures readers can apply their knowledge effectively. The included exercises and quizzes, along with their solutions, provide a guarantee to readers and empower them to create simple yet valuable programs.Learning one computer language facilitates learning other computer languages. This principle arises from rules and logic that connect computer languages. A confirmation of this was when I was asked to teach the C# programming language at the University of Applied Science. Despite having no experience with C#, I dedicated a weekend to diving into the language and realized it wasn't fundamentally different from other object-oriented programming languages.Python is also a language reliant on object-oriented programming principles. Our focus is real-world examples, enabling you to apply these concepts in your programming works. Learning programming is a communication tool with computers, as machines operate using their language defined by specific logical structures and sentences known as statements.Before starting with the chapters, I present some illustrative code examples to provide an overview of the content of this book. The code at the beginning of this book gives you an idea about this book's approach.Why Choose a Text-Based Application?For beginners, it is crucial to start by learning coding in a text-based application. This approach allows you to focus on the fundamentals withoutdealing with the complexities of a graphical user interface. After Learning coding with text-based applications, you can independently explore graphical interfaces through tutorials or any preferred learning method.

The journey of improving coding skills continues even after learning programming. The key question becomes: How can one write code professionally while addressing critical concerns such as code maintainability, code re-usability, security issues, and memory leaks? This book focuses on real-world code examples, aiming to avoid unnecessary, boring, extended theoretical discussions. Instead, it goes straight to the point in coding and offers improvements with clear explanations.Any building is eventually finished, but successful software is never truly finished. New features need to be built, causing the code base to grow over time, and concerns about maintainability grow with it if programmers don't pay serious attention to it.If you asked an expert and a junior programmer to write code for a specific program, you would realize that the expert accomplishes the goal with significantly less code than the junior programmer. Every extra line of code written unnecessarily creates more issues in terms of maintainability, opening the doors to hacking and security vulnerabilities.The problem with coding is not that poorly written code doesn't work; the real problem is that it does. Therefore, it can be challenging for an inexperienced programmer to realize what a better version could be.In this book, I will provide you with common mistakes through different pieces of code that function correctly, but I will also explain why it is crucial to avoid that kind of coding, even though it works.Before diving into the chapters, let's highlight a few code issues to help you determine whether this book will benefit you. The code examples provide a preview of this book's approach to assist you in improving your Java coding. This book systematically addresses issues in the following steps: Presenting common code mistakes through a simple piece of code.Running the code to reveal unexpected outcomes.Explain the case and provide code improvements.This approach ensures you understand how to manage similar code challenges in your programming work.
