Mastering Forecasting Metrics & Accuracy: For Data Science and BeyondForecasting models are only as good as the metrics used to measure them. Yet many teams still rely on outdated or misleading measures like MAPE. This book is the first comprehensive, practitioner-friendly guide dedicated entirely to forecast evaluation metrics — blending clear theory, Python recipes, and real-world case studies.Learn how to avoid common pitfalls, measure bias, handle intermittent demand, and apply advanced metrics like MASE, RMSSE, CRPS, pinball loss, and calibration scores. Each chapter includes formulas, code, and visuals to make concepts easy to apply.Perfect for data scientists, ML engineers, analysts, researchers, and industry professionals in retail, finance, and energy. No heavy math required.Living book: buy once, get free lifetime updates.Measure what matters.

Step inside the world where code becomes story. Creating Text Adventures in Python is your guide to building interactive fiction from scratch, even if you’re new to programming. You’ll learn how to design rooms, puzzles, and branching choices while mastering Python essentials along the way. With each chapter, your simple prototype grows into a full adventure engine—complete with item interactions, save/load systems, and web deployment so friends can play your game online. Whether you dream of crafting fantasy quests, mystery stories, or sci-fi journeys, this book shows you how to bring those worlds to life line by line. By the final page, you won’t just be reading adventures—you’ll be writing them, playing them, and sharing them with the world.

This second edition is for Python programmers who want to get into networking but don't want to feel overwhelmed. My goal is to make you comfortable with reading code and using it to solve real-world networking problems. A lot of people wrote to me saying that it helped them automate tasks that they had been doing manually for years, while others shared how it gave them the confidence to switch careers or take on more advanced responsibilities in their roles.

Bad data breaks good code. You’ve written Python that works perfectly in testing, only to watch it fail in production because of a malformed API request, a messy CSV, or a missing config value. That’s the hidden cost of Python’s flexibility: without runtime validation, you’re always one bad input away from a crash. Enter Pydantic. This book takes you from the foundations of data validation to real-world applications in APIs, data pipelines, configurations, and machine learning workflows. Along the way, you’ll explore practical techniques, advanced features, and alternatives like Marshmallow, attrs, and dataclasses, so you’ll always know which tool is right for the job. If you’re a Python developer, data engineer, or FastAPI user, this is your roadmap to writing safer, cleaner, and more reliable code.
