We covered a lot of ground in Part 1 of our pandas tutorial. We went from the basics of pandas DataFrames to indexing and computations. If you’re still not confident with Pandas, you might want to check out the Dataquest pandas Course.
In this tutorial, we’ll dive into one of the most powerful aspects of pandas – its grouping and aggregation functionality. With this functionality, it’s dead simple to compute group summary statistics, discover patterns, and slice up your data in various ways.
