Pivoting

GroupBy pivoting

GroupBy can be pivoted with pivot method. It will produce a PivotGroupBy.

PivotGroupBy is a dataframe-like structure that combines Pivot and GroupBy, representing a matrix table with vertical Pivot groups (as columns) and horizontal GroupBy groups (as rows), where each cell represents a group corresponding to both the GroupBy and Pivot key.

Reversed order of pivot and groupBy (i.e., DataFrame.pivot + Pivot.groupBy or DataFrame.groupBy + GroupBy.pivot) will produce the same result.

PivotGroupBy can be reduced or aggregated into a DataFrame.
