In this video we'll introduce the Polars package for data analytics in Python. This is a modern, rapidly growing alternative to Pandas for data analysis.
We'll look at the core data structures (Series, DataFrames) and will look at how to select rows/columns, add new columns, drop columns, aggregate and sort data, handle null values, plot data to charts, and how to read/write data from/to files.
