Who this book is for

This book is for data analysts, data scientists, and data engineers who want to learn to use Polars in their workflows. You should have working knowledge of the Python programming language. Preferably, you have experience of working with a DataFrame library such as pandas or PySpark. If you’re looking to improve your data pipelines or data science/analysis workflows with Python Polars, this book is ideal to get you started and be the guide in your journey.

Another audience that may be a good fit for this book is those who know Python, but have not used any DataFrame libraries before. The book is structured so that it starts with basics and fundamental concepts that are important across DataFrame libraries. The complexity of the concepts covered then increases as you progress through the later chapters. Throughout the book, you’ll develop practical skills in using Polars as well as gaining a general understanding of the mechanics of a DataFrame library.
