Accelerated Data Science with Python Polars

Today we will explore Polars - the fastest data science library in Python!! 🐻‍❄️🐻‍❄️🐻‍❄️
The best part is, as of earlier this month, it even got faster with a brand new release of a GPU engine! 🤩
We will learn about Queries, Lazy Frames, Engines, and use them in real life settings, analyzing and visualizing a free dataset with over 260 million rows (and 22GB in size!!! way bigger than what programs like Excel or Sheets can process).
So not only will we learn how to load, compress and process so much data all at once, but we will also plot it with millions of data nodes on the same graph!! 😱
If you think it might be challenging for Polars - prepare to be surprised!!! because that's exactly where it shines, especially when the new GPU engine is involved!
