Описание: Are you ready to start your journey with PySpark on Databricks but don't know where to begin? You're in the right place! This step-by-step tutorial is designed for absolute beginners and will guide you through your very first project: reading a CSV file and creating a DataFrame using a modern, serverless approach.

In this video, we'll demystify the essential code every data professional needs to know. I'll show you the difference between .show() and the powerful display() command that makes Databricks so incredible for data exploration. We'll break down each line of code so you understand not just what to type, but why you're typing it.
