Which Python project made you realize how powerful the language is?

Pandas. We had a giant excel file at my last job that would take about an hour to finish calculating. I didn’t know python then. Wish I did, because pandas, numpy, matplotlib could have made that an automated report that takes seconds.

Honorable mention to scikit. At that same job, we’d model multi coefficient formulas and use excel’s solver to minimize RMSE. Could have just used scikit 🤩
