Useful Python basics

The Python data cleaning examples were easy to follow. I just wish the stats section went a little slower.

I finally got how to use pandas to clean a messy dataset and make a quick chart from it. The step-by-step workflow felt really practical.

Hands-on and clear

The part on building a simple machine learning model stood out, especially how it started with exploring the data first. I would've liked a few more practice exercises, but the real-world examples helped a lot.
