Summary
6.6. Summary#
In this chapter, we explain what dataframes are, why they’re useful, and
how to work with them using pandas
code.
Subsetting, aggregating, joining, and transforming are
useful in nearly every data analysis.
We’ll rely on these operations often in the rest of the book, especially in
the Wrangling Files, Wrangling Dataframes, and Exploratory Data Analysis chapters.
