What you'll learn
Messy, inconsistent data makes analysis unreliable and slow. In this course, Clean and Transform Data with Polars, you will learn how to prepare real-world datasets for analysis using Polars' expression-based API.
First, you'll explore profiling data quality issues such as nulls, duplicates, and invalid values, and determining what must be fixed before analysis. Next, you'll discover what it takes to standardize datasets.
Finally, you'll learn about creating transformed datasets using quick checks such as row counts and null counts, and export the final, analysis-ready data to a durable format, with Parquet as the recommended option.
By the end of this course, you will have the skills and confidence to clean, transform, validate, and export data using Polars for real-world data analysis workflows.
