About the Author

This eBook, "Python Programming for Beginners - Practical Lessons for Building Real-World Applications", provides a comprehensive introduction to Python through ten structured chapters. It starts by explaining why Python is popular, guiding you through environment setup, and teaching essential syntax and data types. You then learn about more advanced subjects such as control flow, functions, and how to write clean, modular code. The book goes deeper into data structures, including dictionaries, lists, tuples, and sets, illustrating how each one is suited for different tasks.

You also discover the fundamentals of object-oriented programming—classes, inheritance, and encapsulation—making it easier to design maintainable applications. The chapters on error handling show how to manage exceptions and create custom error types, ensuring your code remains robust. You learn how to work with files, directories, and popular libraries such as NumPy, Pandas, and Requests, exploring data manipulation and API integration. Finally, the eBook culminates in a real-world project, walking you through step-by-step project organization, core feature implementation, testing, and deployment strategies.

By blending theory with practical examples, this eBook equips you with the confidence and skills needed to develop functional, scalable Python applications that address everyday coding challenges.
