In this tutorial, you will become familiar with polars basics by writing a simple pipeline: you will read data, transform it to make it ready for use, and you will learn how to do that fast. With dataframely schemas, you will upgrade your code from "it works" to "it's beautiful!", and along the way, dataframely will help you eliminate entire classes of bugs you will never have to think about again. After the tutorial, you will be all set to use these tools in your own work.
