Combo-attack!

Transforming DataFrames

In this chapter, you’ll calculate summary statistics on DataFrame columns, and master grouped summary statistics and pivot tables.

Summary statistics

Mean and median

Summarizing dates

Efficient summaries

Cumulative statistics

Counting

Dropping duplicates

Counting categorical variables

Grouped summary statistics

What percent of sales occurred at each store type?

Calculations with .groupby()

Multiple grouped summaries

Pivot tables

Pivoting on one variable

Fill in missing values and sum values with pivot tables

Aggregating DataFrames

Indexes are supercharged row and column names. Learn how they can be combined with slicing for powerful DataFrame subsetting.

Explicit indexes

Setting and removing indexes

Subsetting with .loc[]

Setting multi-level indexes

Sorting by index values

Slicing and subsetting with .loc and .iloc

Slicing index values

Slicing in both directions

Subsetting by row/column number

Working with pivot tables

Pivot temperature by city and year

Subsetting pivot tables

Calculating on a pivot table

Slicing and Indexing DataFrames

Learn to visualize the contents of your DataFrames, handle missing data values, and import data from and export data to CSV files.
