GroupBy

The groupby method is used to group data in a DataFrame or Series based on a given column or index level. The grouped data can then be aggregated, transformed, or filtered using various methods.

Bodo supports the following groupby methods:

Function	Description
pd.core.groupby.Groupby.agg	Compute aggregation using one or more operations over the specified axis.
pd.core.groupby.DataFrameGroupby.aggregate	Compute aggregation using one or more operations over the specified axis.
pd.core.groupby.Groupby.apply	Apply a function to each group.
pd.core.groupby.Groupby.count	Count non-NA cells for each column or row.
pd.core.groupby.Groupby.cumsum	Compute the cumulative sum of the values.
pd.core.groupby.Groupby.first	Compute the first value of the group.
pd.core.groupby.Groupby.head	Return the first n rows of each group.
pd.core.groupby.DataFrameGroupby.idxmax	Compute the index of the maximum value.
pd.core.groupby.DataFrameGroupby.idxmin	Compute the index of the minimum value.
