Python is the foundational, versatile language driving modern data science, machine learning, and software engineering. Mastering efficient and idiomatic Python coding is, therefore, critical for succeeding in high-stakes technical interviews.

This book is a practical guide designed to help you master Python programming through real interview-level coding challenges. With 100 curated problems, it focuses on strengthening your problem-solving skills and deepening your understanding of core concepts. Each challenge is paired with a detailed, easy-to-follow solution. The problems range from basic string manipulation to advanced topics like recursion, dynamic programming, and object-oriented design. The goal is to help you build confidence and improve your coding style step-by-step.

By the end of the book, you will possess the technical fluency in Python and the robust algorithmic thinking needed to confidently approach any technical interview question, directly preparing you to secure your next role as a competent software engineer.
