Data is the driving force of today’s digital economy, and the ability to wrangle, analyze, and model it effectively has become a vital skill across industries. Python’s powerful ecosystem, led by libraries like NumPy, Pandas, and Scikit-learn, enables professionals to transform raw datasets into meaningful insights and build ML solutions that solve real-world problems.

This book offers a practical, hands-on journey into mastering these libraries step-by-step. You will begin with NumPy and Pandas, learning how to manipulate arrays, DataFrames, time series, and large datasets efficiently. The focus then shifts to Scikit-learn, where you will explore classification, regression, clustering, dimensionality reduction, and time series modeling. Along the way, you will explore the practical case studies, including thyroid disease prediction, customer segmentation, and housing price estimation. You will also explore topics such as hyperparameter tuning, ensemble methods, pipelines, and deep neural networks, followed by guidance on deploying ML models with Flask, FastAPI, Docker, and Swagger.

By the end of this book, you will be confident in applying the core data science libraries of Python to real-world problems. You will be able to clean and transform complex datasets, build and optimize robust ML models, and deploy them into production environments as scalable APIs. This book equips you with the practical skills needed to excel in data-driven roles and deliver impactful ML solutions.
