9:12 Is something that is difficult to do in pandas without writing something like a lambda function. “Over” is a nice idea!!

[@martinbel]

I'd guess it's inspired in SQL window functions syntax.

[@stefaandumez2319]

Why do you use .to_pandas() so often ? Can't you do these kind of analysis in Polars? eg histogram, etc...

[@martinbel]

My idea initially was to use polars for data manipulation when data is large enough so pandas doesn't work well. I'm not sure much of this functionality was available when I recorded the videos. But overall, it was a practical decision as I already knew pandas.
